Generally, the proposed site consists of: - The construction of eighteen new residential buildings, a clubhouse and a Gear Garage. - The extension of N 25' Ave. from Tschache Lane to Baxter Lane. - The extension of Turbulence Lane to the "Bozeman West Apartments" development. - The construction of new sewer, water and storm mains. - The construction of a trail along a wetland located east of the property. The purpose of the report and calculations is to demonstrate the following: - Post-development peak runoff does not exceed pre-development (historic) conditions for the 10-year storm event. - The 25-year peak runoff is conveyed by underground storm drain facility with no surface overflow. - Storm water treatment is provided to intercept and contain sediment and floating debris on site, for eventual removal and disposal. 2 Drainage Basins The Voyager Apartments have a drainage area of approximately 14.4 acres (875,510 ft2). Pre-development topography is gradual, about 1 to 3 percent slope from southwest to northeast. Existing groundcover is fallow farmland and grasses. There is a 2.71 Acre existing development in the Northwest corner of the property. An existing stream course and wetland area is located on adjacent property to the east. The proposed property will change the runoff characteristics of the site. The proposed development was divided into sub-basins whose runoff will be directed to storm drain inlets. An existing development has already been constructed and is named "Baxter Apartments". "Baxter Apartment's" stormwater infrastructure is already in place and is self-contained. When the Baxter Apartments Development was built, provisions were made for the development of the subject property. An outlet structure was constructed that is designed to release stormwater at the pre-development rate for the entire 20.1- acre parcel. Refer to SD-1 for pre-development drainage basins and SD-2 for post- development basins. See the site utility plan for more detail on detention and conveyance design. 3 Approach It will be shown that the proposed detention facilities will limit the post-development 10- year peak runoff rate to the pre-development rate. Additionally, the detention facilities will provide effective treatment of storm runoff. All storm drain pipes have been sized to convey the 25-year peak runoff in accordance with the City of Bozeman. Page 3 of 6 Detention ponds shall be sized based on a 10-year, 2-hour storm intensity per the City of Bozeman Design Standards. See Appendix A for rational method detention pond calculations for the 20.1-acre development. A report was written in August 2005 by Allied Engineering for the "Baxter Apartments" development in the northwest corner of the property. The report was written with the entire 20.1-acre parcel in mind. Stormwater runoff from the entire site was to be managed by the stormwater detention pond constructed for the "Baxter Apartments" Development. At the time, the proposed development was scoped as a dense residential development. Now, the proposed development for this 14.33-acre parcel has a higher impervious area than the original development envisioned. Therefore, in the calculations performed for this development, the C value is higher than was originally calculated in the August 2005 report by Allied Engineering. New stormwater infrastructure will be built for the C-Value of the proposed development. The values used in each column of the table are as follows: C (Rational Method runoff coefficient): A weighted runoff coefficient was used in post-development allowable runoff rate and detention pond calculations. The runoff coefficients used below were obtained in the COB Design Manual Table 1-1. The weighted runoff coefficient was calculated as 0.69. • The existing Stormwater Pond was characterized as Open Space in the Gallatin County Parcel Map. A C value of 0.2 was used for this 0.71 acre area. • The existing development was characterized as dense residential in accordance with the Stormwater Report prepared in 2005. A C value of 0.587 was calculated for this 3.15-acre development. • The remainder of the area was divided into subbasins, and individual areas were calculated. These areas are included in the Inlet Calculations in Appendix D. A C value of 0.721 was used for the remaining 16.24 acre area. Area: Areas were calculated in AutoCAD and verified with Gallatin County Parcel Data. Intensity The rainfall intensity value of I = 0.41 in/hr is used per the City of Bozeman design standards for a 10-year, 2-hour storm per City of Bozeman Design Standards page 25 C(5). All other intensities used in calculations were calculated directly from the applicable power curve equations listed in the COB Design Manual Figure 1-2 and 1-3. 3 Detention Ponds As discussed previously, stormwater runoff from the proposed development will be retained by surface storm water detention basins. In accordance with the City of Bozeman Design Standards, the detention facilities have been designed based on the 10-year, 2-hour storm event. A summary of the design parameters and sizing of the reservoirs is provided in Table 1 and the analysis are included in Appendix A.

The Runoff Reduction Volume calculated was less than the volume provided by the detention facilities.

Provisions for overland flow of larger, less frequent storms up to the 100-year storm will be incorporated into the site grading. Calculations are provided to ensure pipe size is adequate for all pipes. Pipe diameter will be sized for expected flow using an SSA model, and will be lain, at a minimum, per DEQ-2 33.41 slopes. A minimum pipe diameter of 12-inches at a minimum slope of 0.15% (per DEQ- 2) was chosen for the storm main conveyance design. The site's northernmost 4 runs of storm main are sized at 24" SDR35 to convey expected flows. Minimum slope for 15" and 18" storm main is 0.15% and 0.12% respectively per DEQ-2. The Culvert below Turbulence lane will be a 18" PVC at a slope of 1.56%. It will be 98' long with: trash racks, wing walls, erosion control and a minimum velocity of 3-fps during the 25-year design storm. See Appendix D for the conveyance calculations for the storm drain culvert. The culvert that connects the wetlands will be a 45" x 29" RCP Elliptical Pipe, and it will be 115.75 ft long. This pipe was chosen because of it's equivalent dimensions to a 36" RCP pipe. The downstream culverts on this watercourse are 36" RCP, a 36" Page 5 of 6 RCP will provide equivalent conveyance to up-stream and down-stream culverts. Swales are designed to be 1' deep with 4:1 side slopes and run at 1.12% and 1.03% respectively for the north and south swales. 5 Groundwater A July 2022 report was produced by Terracon. During their explorations, groundwater was encountered between the depths of 5.5-11' below existing ground. Mottling was not mentioned in the report. Therefore, it is less likely that groundwater rises too far above the 5'-6' depth during most normal years. A 2005 report by Allied Engineering found that groundwater depth rises to 2'-3' within the eastern one-third of the site. According to the Geotechnical report produced by Terracon, "all borings were backfilled with auger cuttings or finished as groundwater monitoring wells upon completion." 6 Maintenance Considerations Storm Water Conveyance Facilities Storm drain inlets, catch basins, and piping should be inspected at least once per year and following large storm events. Any necessary repair or maintenance should be prioritized and scheduled through the spring, summer, and fall. These items may include inspecting for any damage, removing blockages, cleaning and flushing the length of pipes, establishing vegetation on bare slopes at or near inlets, and sediment removal. Storm Water Detention Facility Maintenance of detention basin is also essential. General objectives of maintenance are to prevent clogging, standing water and the growth of weeds and wetland plants. This requires frequent unclogging of the outlets, inlets, and mowing. Cleaning out sediment with earth-moving equipment may also be necessary in 10 to 20 years. A Storm Water Operations and Maintenance Manual has been completed for the project, and it is included in Appendix I. 7 Conclusions The included analyses and calculations show that the storm water management system for the proposed development will adequately handle the design storm events. During the 100-year design storm recurrence interval, ponding may occur at inlets due to their capacities; however, depths are estimated to remain at or below the top-back of curb in the lower areas of the site. If clogging of inlets or larger storm water runoff events occur provisions have been included in the design for overflows without presenting a hazard to the public or adjacent property. Based on the included analyses and calculations, the proposed storm water management system meets the requirements of the City of Bozeman Design Standards and Specifications Policy.

owner shall designate a qualified professional entity or individual to perform all monitoring. The name, address and telephone number of the entity or individual shall be provided to the City of Bozeman Public Works Department. The owner's representative shall be required to keep a log of all required inspections and maintenance required. The log shall be made available to the City of Bozeman Public Works Department for review as requested. Land Use and Site Area: The proposed development is located in Bozeman, Montana on Tract 1 of COS 1256 less Minor Subdivision 404 in Section 2 of Township 2 South, Range 5 East Principal Meridian Montana. Generally, the subject property is bordered by Tscahche Lane to the south, N 27t" Ave to the west and Baxter Lane to the north. The proposed site consists of 3 apartment buildings, 12 rowhomes, a clubhouse and 3 single- family homes on a total site area of 14.4 acres. The drainage area for the proposed development is approximately 15.56 acres including: 4.93 acres of landscape area, 10.7 acres of Impervious area, 0.1 acres of gravel, 3.3 acres of roof and 1.05 acres of wetland. Stormwater Management System: The stormwater management system for the proposed development includes storm drain piping, culverts, and swales. Inlets and manholes have a sump section for sediment collection. All water will be detained in a detention pond and released at the pre-development rate. We create solutions that build better communities AN EMPLOYEE-OWNED COMPANY • AN EQUAL OPPORTUNITY EMPLOYER—MINORITIES/FEMALES/DISABLED/VETERANS Morrison Maierle engineers•surveyors•planners•scientists Inspection and Maintenance: Stormwater facilities and permanent Best Management Practices must be inspected in accordance with this document. All documentation on scheduled inspections, times of inspections, maintenance completed, remedial actions taken to make repairs, and any modifications or reconstruction of the storm system shall be maintained on-site. Disposal of the accumulated sediment must be in accordance with all applicable local, state, and federal guidelines and regulations. If any drainage structure or outfall indicates the presence of petroleum, the petroleum Pavement Sweeping and Vacuuming: All paved areas shall be swept twice a year, scheduled in spring and fall. Inlets and Catch Basins: All inlets and catch basins shall be inspected to ensure they have adequate sump capacity, hoods are in place, frames and grates are not damaged, and internal concrete and grout is intact. ❑ Inspect catch basins four times per year and following large storm events. ❑ Clean sump annually or whenever basin sump becomes filled with sediment to half its depth (1'-0"). ❑ Storm drain curb inlets and inlet grates shall be maintained year-round to remove any trash,vegetation and other debris that may cause flow restrictions and unintended ponding of storm water. If inspection indicates the presence of petroleum, the petroleum material shall be removed and disposed of immediately in accordance with applicable regulations. Piping: All storm drain piping shall be inspected for any damage and/or blockages. ❑ Inspect piping bi-annually and following large storm events. ❑ Length of pipes should be cleaned and flushed as field determined. ❑ Any sediment,trash,vegetation, and other debris shall be removed upon observation. Surface Detention System: Maintenance of the surface retention basin is also essential. General objectives of maintenance are to prevent clogging, standing water and the growth of weeds and wetland plants. This requires Morrison Maierle engineers•surveyors•planners•scientists frequent unclogging of the outlets, inlets, and mowing. Cleaning out sediment with earth-moving equipment may also be necessary in 10 to 20 years. ❑ Inspect surface every three(3) months and following large storm events. ❑ Remove any accumulated trash. ❑ Sediment removal is to be provided as required. More frequent sediment removal via hand tools may reduce or eliminate the need for earth-moving equipment for sediment removal at a later date. ❑ Storm water ponds shall be mowed from May through September a minimum of every six weeks to maintain the function of the pond and minimize reductions in storage volume. In the event excessive sediment deposits are observed, sediment shall be removed immediately to ensure storage is not compromised. ❑ Landscaped areas and side slopes adjacent to ponds shall be inspected annually to determine if erosion and loss of vegetation are occurring. If so, these items shall be repaired and underlying cause corrected. If excessive erosion or loss of vegetation is observed, stabilization and revegetation shall be completed. If inspection indicates the presence of petroleum, the petroleum material shall be removed and disposed of immediately in accordance with applicable regulations. Conveyance Swales: Swales shall be visually inspected every six weeks. Any sediment, trash, erosion, or debris shall be corrected upon inspection. Vegetation height shall be minimum of 2 inches. ❑ Inspect swales in accordance with the Maintence schedule outlined below. Biofiltration Swale Maintenance Schedule (2017 Stormwater BMP Manual, 5.6-10): Activity • Make sure full coverage of turf grass or erosion control fabric has been achieved following construction, both on the channel bed and side slopes Upon • Inspect the swale during and after runoff events to ensure that the swale is operating as establishment designed and inspect for erosion • Remove litter/debris from all components of the biofiltration swale • Manage all vegetation during the growing season and maintain grass heights as specified As needed during the design documents.Remove all clippings. • Ensure that the contributing drainage area is clear of debris ■ Ensure that the contributing drainage area is stabilized and perform spot-reseeding if or where necessary Quarterly • Repair undercut and eroded areas as needed at swale inflow and outflow structures • If applicable, inspect upstream and downstream of check dams for evidence of undercutting or erosion,and remove trash or blockages at weepholes ■ Reseed as needed during fall seeding season to maintain 90%turf grass cover ■ Remove any accumulated sand or sediment deposits behind check dams • Examine channel bottom for evidence of erosion,braiding,excessive ponding or dead grass • Check inflow points for clogging and remove any sediment Annually • Inspect side slopes and filter strips for evidence of erosion ■ Inspect all components of the biofiltration swale in accordance with an approved inspection form according to local jurisdiction requirements.An example inspection form is provided in Appendix F.

26217114 EXECUTIVE SUMMARY This Phase I Environmental Site Assessment (ESA) was performed in accordance with Terracon Proposal No. P26217114, dated September 2, 2021, and was conducted consistent with the procedures included in ASTM E1527-13, Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process. The ESA was conducted under the supervision or responsible charge of Robyn R. Sargent, CHMM, Environmental Professional. Erika N. Sturn performed the site reconnaissance on November 1, 2021. Findings and Opinions A summary of findings is provided below. It should be recognized that details were not included or fully developed in this section, and the report must be read in its entirety for a comprehensive understanding of the items contained herein. Site Description and Use The site consists of two parcels of undeveloped land totaling approximately 15.14-acres located at the northeast corner of North 27th Avenue and Tschache Lane in Bozeman, Montana. Historical Information The site and surrounding properties, with the exception of Baxter Lane, have been largely undeveloped from at least 1947 until sometime between 2006-2009. South of the site, development of Tschache Lane took place between 2006 and 2009 followed by the construction of Rose Park with its associated walking trails and a parking lot by 2013. From 1947 until at least 2002, the northwest adjoining property was developed with two or three residential dwellings, but these were demolished and replaced with an apartment complex by 2006. North 27th Street, located west of the site, was developed by 2006 followed by residential development by 2009. The east adjoining properties consisted of vacant land until around 2009, when developed with a condominium complex. Records Review Select federal and state regulatory databases were reviewed. The site was not listed in any of the reviewed databases. One Leaking Underground Storage Tank (LUST) facility was identified within the specified search radii of within 0.5 miles of the site. The facility listed in the database report does not appear to represent a recognized environmental condition (REC) to the site at this time based upon regulatory status, apparent topographic gradient relative to the site, and/or distance. Local area knowledge and personnel provided information regarding the Bozeman Solvent Site (BSS), which consists of a halogenated solvent groundwater plume impacting shallow groundwater across a large area of Bozeman. The source of this contamination was a historical dry-cleaning facility located in a shopping center at 1625 West Main Street, Bozeman located Responsive ■ Resourceful ■ Reliable i Phase I Environmental Site Assessment Irerracon Approximate 15.14-Acre Site Bozeman, MT November 10, 2021 Terracon Project No. 26217114 over 6,000 feet southeast of the subject site. Review of updated maps of the approximated solvent plume and associated controlled groundwater areas (CGWA) show the site to be located approximately 500 feet west of the BCGWA boundary. Furthermore, the controlled groundwater area extends 1,000 radially from the estimated solvent plume indicating that the site is likely at least 1,500 feet outside of the bounds of the solvent plume. Additionally, Montana Department of Environmental Quality (MDEQ) provided information from a survey of monitoring wells with data as recent as 2020. Concentrations of halogenated solvents from 2020 samples were not detected or were reported below site-specific cleanup levels. Based on the distance from the site and data provided by MDEQ, the Bozeman Solvent Site does not appear to constitute a REC to the site at this time. Site Reconnaissance Two pad-mounted transformers were identified on the southwest corner and south-central margin of the site during the site reconnaissance and are discussed in Section 5.3 of this report. Adjoining Properties The site is abutted to the north by Baxter Lane followed by undeveloped/vacant land (no address identified); abutted to the east by Baxter Springs Condos (2222 Baxter Lane) and vacant land under construction (no address identified); to the south by Tschache Lane followed by Rose Park (2420 Tschache Lane) and vacant land (1660 North 27th Street); and to the west by Baxter Apartments (2565-2635 Trade Wind Lane), North 27th Street followed by West Winds Subdivision (1808-1892 Leeward Court) and Stoneridge Apartments (2715 Tschache Lane). RECS were not observed with the adjoining properties. Additional Services Per the agreed scope of services specified in the proposal, the following additional services (e.g. radon records review, wetlands records review, threatened/endangered species records review, historic properties/archeological resources records review, and ASTM E 2600-15 Vapor Encroachment Screening)were conducted. The site is located within EPA Zone 1 (areas where radon concentration exceeds 4.0 picoCuries per liter. The average residential radon concentration from the study for Gallatin County is 2.844 pCi/L on the 1st floor of structure and 7.971 pCi/L within basement areas. The study included tests in 31 homes in Gallatin County, 11% of which exceeded the EPA action level on the first floor and 84% exceeded the EPA action level in the basement. Based on this information, the site is considered to have a high potential for elevated indoor concentrations of radon gas; however, testing would be required to evaluate site-specific concentrations of radon gas. Terracon's desktop review identified an emergent freshwater wetland area (PEM1A) along the eastern boundary of the site. The desktop review also identified a freshwater pond along the northern boundary of the site; however, this feature was not observed during the site reconnaissance. Vegetation observed in association with this feature does suggest it is a Responsive ■ Resourceful ■ Reliable ii Phase I Environmental Site Assessment Irerracon Approximate 15.14-Acre Site Bozeman, MT November 10, 2021 Terracon Project No. 26217114 wetland, but any formal determination is beyond the scope of this assessment. The Limited Wetland Review does not constitute a formal determination and/or delineation of a potentially jurisdictional wetland, which requires (among other procedures) a formal field investigation including hand-dug soil stations with vegetation and hydrologic indicators identification, as set forth in 1987 Corps of Engineers Wetland Delineation Manual and further amended by the applicable Regional Supplements to the Corps of Engineers Wetland Delineation Manual. Three federally threatened species, Yellow-billed Cuckoo, Canada Lynx and Grizzly Bear, and numerous state species of concern were identified for the site. While the site is undeveloped, it is surrounded by residential developments and is not comprised of sub-alpine boreal forest, conifer forest, or riparian forest preferred by the threatened species. In addition, multiple state species of concern were identified for the site; however, it is not a regulatory or statutory classification. The site may support the identified state species of concern, but this information is intended to help developers and resource managers make proactive and informed decisions regarding development. There is currently not a state requirement for species of concern and, based on the recent development of the surrounding areas, the site is likely not a viable habitat for these species. Cultural resources are comprised of historic properties and archeological artifacts. The review included the National Register of Historic Places and Freedom of Information Act (FOIA) publicly available information from the State Historic Preservation Office (SHPO) database review. Cultural resources or structures of historical significance were not documented on the National Register of Historic Places or State Historic Preservation Office database. Terracon conducted a Tier 1 Vapor Encroachment Screening (VES), in general accordance with the procedures included in ASTM E 2600-10, Standard Guide for Vapor Encroachment Screening on Property Involved in Real Estate Transactions. The purpose of the Tier 1 VES is to evaluate whether a vapor encroachment condition (VEC) may be present at the site. A VEC is defined by ASTM as the "presence or likely presence of chemical(s) of concern (COC) vapors in the subsurface of the target property caused by the release of vapors from contaminated soil or groundwater or both either on or near the target property as identified by the Tier I procedures in the Guide." This purpose was pursued through use of information collected in conjunction with the ESA, including existing/planned use of the site, type of structures located on the site, surrounding property description, user information, historical and physical records review, regulatory database review, manmade or natural conduits, as applicable, and a visual noninvasive reconnaissance of the site and adjoining properties. The review is further discussed in Section 7.5 of this report. VECs were not identified in connection with the site. Significant Data Gaps No significant data gaps were identified. Responsive ■ Resourceful ■ Reliable iii Phase I Environmental Site Assessment 1��rr�cor� Approximate 15.14-Acre Site Bozeman, MT November 10, 2021 Terracon Project No. 26217114 Conclusions We have performed a Phase I ESA consistent with the procedures included in ASTM Practice E 1527-13 at the approximately 15.14-acre site at North 27t" Street and Tschache Lane, Bozeman, Gallatin County, Montana, the site. Recognized environmental conditions (RECs), Historical RECs (HRECs), or Controlled RECs (CRECs) were not identified in connection with the site. Recommendations Based on the scope of services, limitations, and conclusions of this assessment, Terracon did not identify RECs, HRECs, or CRECs. As such, no additional investigation is warranted at this time.

The site and adjoining properties are depicted on the Site Diagram, which is included as Exhibit 2 of Appendix A. Acronyms and terms used in this report are described in Appendix F. 1.2 Scope of Services This Phase I ESA was performed in accordance with Terracon Proposal No. P26217114, dated September 2, 2021, and was conducted consistent with the procedures included in ASTM El527-13, Standard Practice for Environmental Site Assessments: Phase 1 Environmental Site Assessment Process. The purpose of this ESA was to assist the client in developing information to identify RECs in connection with the site as reflected by the scope of this report. This purpose was undertaken through user-provided information, a regulatory database review, historical and physical records review, interviews, including local government inquiries, as applicable, and a visual noninvasive reconnaissance of the site and adjoining properties. Limitations, ASTM deviations, and significant data gaps (if identified) are noted in the applicable sections of the report. ASTM E1527-13 contains a definition of "migrate/migration," which refers to "the movement of hazardous substances or petroleum products in any form, including, for example, solid and liquid at the surface or subsurface, and vapor in the subsurface." By including this explicit reference to migration in ASTM E1527-13, the Standard clarifies that the potential for vapor migration should be addressed as part of a Phase I ESA. This Phase I ESA has considered vapor migration in evaluation of RECs associated with the site. As requested by the client, the following additional services were performed: ■ Radon Records Review ■ Wetland Records Review Responsive ■ Resourceful ■ Reliable 1 Phase I Environmental Site Assessment Irerracon Approximate 15.14-Acre Site Bozeman, MT November 10, 2021 Terracon Project No. 26217114 Threatened/Endangered Species Records Review Historic Properties/Archaeological Resources Review ASTM E 2600-15 Vapor Encroachment Screening 1.3 Standard of Care This ESA was performed in accordance with generally accepted practices of this profession, undertaken in similar studies at the same time and in the same geographical area. We have endeavored to meet this standard of care, but may be limited by conditions encountered during performance, a client-driven scope of work, or inability to review information not received by the report date. Where appropriate, these limitations are discussed in the text of the report, and an evaluation of their significance with respect to our findings has been conducted. Phase I ESAs, such as the one performed at this site, are of limited scope, are noninvasive, and cannot eliminate the potential that hazardous, toxic, or petroleum substances are present or have been released at the site beyond what is identified by the limited scope of this ESA. In conducting the limited scope of services described herein, certain sources of information and public records were not reviewed. It should be recognized that environmental concerns may be documented in public records that were not reviewed. No ESA can wholly eliminate uncertainty regarding the potential for RECs in connection with a property. Performance of this practice is intended to reduce, but not eliminate, uncertainty regarding the potential for RECs. No warranties, express or implied, are intended or made. The limitations herein must be considered when the user of this report formulates opinions as to risks associated with the site or otherwise uses the report for any other purpose. These risks may be further evaluated — but not eliminated — through additional research or assessment. We will, upon request, advise you of additional research or assessment options that may be available and associated costs. 1.4 Additional Scope Limitations, ASTM Deviations and Data Gaps Based upon the agreed-on scope of services, this ESA did not include subsurface or other invasive assessments, vapor intrusion assessments or indoor air quality assessments (i.e. evaluation of the presence of vapors within a building structure), business environmental risk evaluations, or other services not particularly identified and discussed herein. Credentials of the company (Statement of Qualifications) have not been included in this report but are available upon request. Pertinent documents are referred to in the text of this report, and a separate reference section has not been included. Reasonable attempts were made to obtain information within the scope and time constraints set forth by the client; however, in some instances, information requested is not, or was not, received by the issuance date of the report. Information obtained for this ESA was received from several sources that we believe to be reliable; nonetheless, the authenticity or reliability of these sources cannot and is not warranted hereunder. This ESA was further limited by the following: Responsive ■ Resourceful ■ Reliable 2 Phase I Environmental Site Assessment Irerracon Approximate 15.14-Acre Site Bozeman, MT November 10, 2021 Terracon Project No. 26217114 Historical information was not provided back to 1940. Uses of the site were described only as far back as 1947; however, based on the undeveloped nature of the site, this does not represent a significant data gap. At the issuance of this report, a response regarding a request for pertinent environmental records had not been received from the Fire Department, which represents a data gap. Based on the undeveloped nature of the site, this data gap is not considered significant. An evaluation of the significance of limitations and missing information with respect to our findings has been conducted, and where appropriate, significant data gaps are identified and discussed in the text of the report. However, it should be recognized that an evaluation of significant data gaps is based on the information available at the time of report issuance, and an evaluation of information received after the report issuance date may result in an alteration of our conclusions, recommendations, or opinions. We have no obligation to provide information obtained or discovered by us after the issuance date of the report, or to perform any additional services, regardless of whether the information would affect any conclusions, recommendations, or opinions in the report. This disclaimer specifically applies to any information that has not been provided by the client. This report represents our service to you as of the report date and constitutes our final document; its text may not be altered after final issuance. Findings in this report are based upon the site's current utilization, information derived from the most recent reconnaissance and from other activities described herein; such information is subject to change. Certain indicators of the presence of hazardous substances or petroleum products may have been latent, inaccessible, unobservable, or not present during the most recent reconnaissance and may subsequently become observable (such as after site renovation or development). Further, these services are not to be construed as legal interpretation or advice. 1.5 Reliance This ESA report is prepared for the exclusive use and reliance of The Voyager Company LLC. Use or reliance by any other party is prohibited without the written authorization of The Voyager Company LLC and Terracon Consultants, Inc. (Terracon). Reliance on the ESA by the client and all authorized parties will be subject to the terms, conditions and limitations stated in the proposal, ESA report, and Terracon's Agreement for Services. The limitation of liability defined in the Agreement for Services is the aggregate limit of Terracon's liability to the client and all relying parties. Continued viability of this report is subject to ASTM E1527-13 Sections 4.6 and 4.8. If the ESA will be used by a different user (third party) than the user for whom the ESA was originally prepared, the third party must also satisfy the user's responsibilities in Section 6 of ASTM E1527-13.

Mr. Gould indicated that he has been familiar with the site since 2004 when Fairview Investments assumed ownership. Mr. Gould stated that there have never been any underground storage tanks or septic systems associated with the site or surrounding properties and was unaware of any environmental concerns associated with the site. Mr. Gould also noted that the site is regularly mowed and weed management practices are conducted in adherence with the City of Bozeman requirements. The northern boundary of the site contains a wetland area that was initially part of a stormwater and runoff management system. The feature has a storm drain that transports overland flow to the city wastewater system. Since 2004, Mr. Gould stated that he has never observed any standing water to indicate this wetland feature is a pond. Mr. Gould was unaware of any pending environmental litigation, threatened environmental litigation, past environmental litigation, notices of possible violation of environmental law, notices of possible liability, or notices of potential environmental concerns associated with the site. 3.7 Prior Report Review Terracon requested the client provide any previous environmental reports they are aware of for the site. Previous reports were not provided by the client to Terracon for review. 4.0 RECORDS REVIEW Regulatory database information was provided by EDR, a contract information services company. The purpose of the records review was to identify RECs in connection with the site. Information in this section is subject to the accuracy of the data provided by the information services company and the date at which the information is updated. The scope herein did not include confirmation of facilities listed as "unmappable" by regulatory databases. In some of the following subsections, the words up-gradient, cross-gradient and down-gradient refer to the topographic gradient in relation to the site. As stated previously, the groundwater flow direction and the depth to shallow groundwater, if present, would likely vary depending upon seasonal variations in rainfall and the depth to the soil/bedrock interface. Without the benefit of on-site groundwater monitoring wells surveyed to a datum, groundwater depth and flow direction beneath the site cannot be directly ascertained. 4.1 Federal and State/Tribal Databases Listed below are the facility listings identified on federal and state/tribal databases within the ASTM-required search distances from the approximate site boundaries.

The report listed one facility in the unmapped section. Determining the location of unmapped facilities is beyond the scope of this assessment; however, none of these facilities were identified as the site or adjacent properties. These facilities are listed in the database report in Appendix D. 4.2 Local Agency Inquiries Agency Contacted/ Contact Method Response Gallatin County Health Department According to Mr. Nicholas Haskell of the Gallatin County Health by e-mail Department, there is no record of the site listed in any database nicholas.haskell@gallatin.mt.gov used by the Department (including, but not limited to septic systems, complaints, spills/contaminations, etc.). Mr. Haskell stated that the site is located within Bozeman city limits and is connected to city water and wastewater services. Mr. Haskell also stated that the site is located approximately 500 feet west of a controlled ground water area (CGWA), which is associated with the Bozeman Solvent Site. Bozeman Fire Department A response had not been received by the Fire Department at the by online form submission issuance of this report. bozeman.net/government/city- clerk/records-request 4.3 Local Area Knowledge The Bozeman Solvent Site (BSS) is a chlorinated solvent plume impacting groundwater across a large area of Bozeman. The chlorinated solvent plume consists primarily of perch loroethylene, a dry-cleaning fluid also called tetrachloroethylene and abbreviated as PCE. Trichloroethene (TCE), cis-1,2-dichloroethene (DCE), and vinyl chloride (which are degradation products of PCE) have also been detected in the BSS chlorinated solvent plume. The source of the contamination is a historical dry-cleaning facility located in a shopping center at 1625 West Main Street in northwest Bozeman. The BSS groundwater contamination plume extends north from the shopping center to the north side of the East Gallatin River, approximately 1.5 miles away from the site. Groundwater contamination has been documented between six and 130 feet (ft) below ground surface (bgs) at the BSS. Terracon reviewed the MDEQ Remediation Division's Record of Decision, Bozeman Solvent Site, August 2011, for the purpose of this report (select figures from the document are included in Appendix C of this report). Based on a review of the Record of Decision (ROD); the subject site is located approximately 500 feet west of the controlled ground water area (CGWA), and is not within the delineated boundaries of the BSS groundwater contamination plume. However, the delineated boundaries determined in the 2011 Report are estimations and are not the actual boundaries of the BSS, therefore the plume actual boundaries may differ. Additionally, the ROD Responsive ■ Resourceful ■ Reliable 10 Phase I Environmental Site Assessment 1��rracon Approximate 15.14-Acre Site Bozeman, MT November 10, 2021 Terracon Project No. 26217114 states that a Controlled Ground Water Area (CGWA) was established in association with the solvent plume and extends approximately 1,000 feet from the plume. Terracon also contacted Ms. Kate Fry of the Montana DEQ for more information pertaining to the BSS in order to determine if more information was available pertaining to the concentrations of PCE near the site and if the site would likely be impacted by soil vapor. According to Ms. Fry a vapor intrusion investigation was conducted on October 26, 2010 by Kleinfelder West Inc. located in the neighborhood north of Bozeman High School. Based on the results and conclusions of the vapor intrusion investigation MDEQ determined that it would not require further action to address subsurface soil vapor or indoor air north of West Beal Street, which is located adjacent north of the shopping center and approximately 1.2 miles southeast of the site. Ms. Fry also provided information that a Groundwater Monitoring Report dated February 15, 2021 was performed by Tasman Geosciences. Based on the results of the monitoring report Monitoring Well (M-5) is the closest upgradient monitoring well to the site, which is approximately 2,500 feet southeast of the site. Ms. Fry further explained that the PCE concentrations for M-5 have been less than the site-specific cleanup level (SSCL) for PCE in groundwater (5 pg/L) and the monitoring well pair (M-7/M-8) upgradient of M-5 shows no PCE detected or PCE decreasing to less than the SSCL over the same time period. While review of available records provided no indications that the BSS chlorinated solvent plume is currently impacting the site, or will impact the site, subsurface materials can be highly variable from one location to another and rate and direction of groundwater flow can be impacted by various factors. Mr. Nick Haskell of the Gallatin County Health Department stated that the site is located at least 500 feet outside the most recent solvent site boundary, as well as the accompanying controlled groundwater area. Given that the CGWA extends approximately 1,000 feet radially from the solvent plume and the site is located at least 500 feet outside the CGWA, it follows that the site is likely 1,500 feet away from the solvent plume and associated environmental impacts. Based on information provided by Ms. Fry regarding recent groundwater concentrations, information provided by Mr. Haskell, and distance of the solvent plume relative to the site, the Bozeman Solvent Site does not constitute a REC to the site at this time. 5.0 SITE RECONNAISSANCE 5.1 General Site Information Information contained in this section is based on a visual reconnaissance conducted while walking through the site.

The pad-mounted transformers appeared to be in good physical condition with no staining, stressed vegetation, or indications of releases of polychlorinated biphenyls (PCBs) identified in the vicinity of the transformers. NorthWestern Energy maintains responsibility for the transformer, and if the transformer is "PCB containing", Northwestern Energy is not required to replace the transformer fluids until a release is identified. However, indications of a current or prior release were not observed in the vicinity of the electrical equipment during the site reconnaissance. Based on the lack of indications of current and prior releases, the pad-mounted transformer does not constitute a REC. Other Notable Site Features During the site reconnaissance, a potential wetland area was identified along the northern boundary of the site. When referring to the map obtained from the National Wetland Inventory (NWI) the feature is depicted as a freshwater pond. At the time of the site reconnaissance, a pond was not observed and the feature appeared dry; however, plant species with high moisture requirements commonly associated with certain wetland habitats (including willow species and typha) were observed, which suggests this feature may be a wetland area. Please note that this observation does not constitute a formal wetland delineation or determination of the wetland classification, which is beyond the scope of this assessment. 6.0 ADJOINING PROPERTY RECONNAISSANCE Visual observations of adjoining properties (from site boundaries) are summarized below.

Responsive ■ Resourceful ■ Reliable 14 Phase I Environmental Site Assessment Irerracon Approximate 15.14-Acre Site Bozeman, MT November 10, 2021 ■ Terracon Project No. 26217114 7.0 ADDITIONAL SERVICES Per the agreed scope of services specified in the proposal, the following additional services (e.g. radon records review, vapor encroachment screen, wetland records review, threatened/endangered species records review, and historic properties/archaeological resources review) were conducted. 7.1 Radon Records Review Radon is a naturally occurring radioactive gas produced through the natural decay of uranium to stable lead. It is odorless, tasteless, and invisible. Elevated concentrations of radon can be found in soils and rocks containing uranium, granite, shale, phosphate, and pitchblende. Locations of these materials are highly unpredictable. Elevated levels of radon may also be found in soils containing certain types of industrial wastes, such as the by-products from uranium or phosphate mining. Radon can accumulate inside structures at concentrations that may pose risks to human health. Indoor radon levels are influenced by building construction and the concentration of radon in the underlying soil. Terracon reviewed the Geocheck — Physical Setting Source Map Findings for Radon prepared by EDR to identify the site location in terms of potential for average indoor radon concentrations. The study indicated the site is located in EPA Zone 1, which has a predicted average indoor screening level of >4 picoCuries (pCi/L). The EPA recommends a guideline action level of 4.0 pCi/L for annual average indoor radon concentrations in residential properties. The action level is based on an exposure of 18 hours per day for 40 years. According to a U.S. Department of Energy environmental assessment, radon is much less of a concern in commercial buildings than in residential buildings as these buildings usually have mechanical ventilation and occupants are typically not in the buildings as many hours a week as they are in their homes. No action level has been established for commercial buildings or occupational exposure. The average residential radon concentration from the study for Gallatin County is 2.844 pCi/L on the 11t floor of structure and 7.971 pCi/L within basement areas. The study included tests in 31 homes in Gallatin County, 11% of which exceeded the EPA action level on the first floor and 84% exceeded the EPA action level in the basement. Based on this information, the site is considered to have a high potential for elevated indoor concentrations of radon gas. However, testing would be required to evaluate site-specific concentrations of radon gas. 7.2 Wetland Records Review The U.S. Army Corps of Engineers (USACE) regulates jurisdictional wetlands and other waters of the U.S. under Section 10 of the Rivers and Harbors Act and Section 404 of the Clean Water Act. Terracon conducted a limited desktop review of the site to identify areas mapped by the resources below as potentially exhibiting characteristics of wetlands and/or other waterbodies Responsive ■ Resourceful ■ Reliable 15 Phase I Environmental Site Assessment Irerracon Approximate 15.14-Acre Site Bozeman, MT November 10, 2021 Terracon Project No. 26217114 that may be subject to regulation under the USACE. This review may not identify state/locally designated wetlands. This desktop review is not a thorough review of wetlands and may not identify all resources present. Terracon reviewed the following resources to identify areas mapped as indicating the potential presence of jurisdictional waters of the U.S., including wetlands, on the site: Topographic Map The United States Geologic Survey (USGS) 7.5-Minute Topographic Map of the subject site was reviewed to identify drainages or other potential waters of the U.S. within the project site. A portion of the Topographic Quadrangle can be seen as Exhibit 1 in Appendix A. Based on the USGS map; water bodies are not depicted to occur on the site. National Wetland Inventory Map National Wetland Inventory (NWI) data for the project site was reviewed to identify potential wetland areas. NWI data for the project site was published by the U.S. Department of the Interior's Fish and Wildlife Service and depicts possible wetland areas based on stereoscopic analysis of high-altitude aerial photographs. The review of the NWI data indicates a freshwater emergent wetland (PEM1A) area located along the eastern site boundary. The NWI map data for the project area is included in Appendix C. Terracon's review of the above resources indicated a mapped wetland on the site. The review of the NWI data indicates a freshwater emergent wetland (PEM1A) area located along the eastern site boundary. Additionally, the NWI map indicated the presence of a freshwater pond located along the northern boundary of the site. The pond was not observed during the site reconnaissance; however there appeared to be a wetland feature at the indicated location on the NWI map. The feature was dry but vegetation (i.e. various willow species and typha (cattail)) suggests that this area receives more moisture than the surrounding areas of the feature and is likely a wetland area. The NWI map data for the project area is included in Appendix A as Exhibit 3. Please note this Limited Wetland Review does not constitute a formal determination and/or delineation of a potentially jurisdictional wetland, which requires (among other procedures)a formal field investigation including hand-dug soil stations with vegetation and hydrologic indicator identification, as set forth in 1987 Corps of Engineers Wetland Delineation Manual and further amended by the applicable Regional Supplements to the Corps of Engineers Wetland Delineation Manual. To obtain a formal determination from the USACE regarding jurisdictional status, a wetland/waters of the U.S. delineation could be conducted by a wetland scientist and submitted to the USACE (or in certain geographies the participating state agency) for a jurisdictional determination. Note that the USACE is not required to respond to determination requests within a particular timeframe unless the submittal also includes a permit application.

Three federally threatened and state threatened species were identified for the site. The species identified are the Grizzly Bear, Canada Lynx, and Yellow-billed Cuckoo; however, the site is situated within a developed area of the city of Bozeman and the preferred habitats of these species (sub-alpine, conifer, and riparian forests) were not observed on site Additionally, multiple state species of concern were identified for the site, but this designation is neither a regulatory or statutory classification. The site may support the identified state species of concern, but this information is intended to help developers and resource managers make proactive and informed decisions regarding development. There is currently not a state requirement for further identification or mitigation of species of concern. While several species of concern were identified for the site, recent development of the surrounding areas suggests that the site is likely not a viable habitat for these species. This review is limited and does not constitute an evaluation of habitat suitability or presence/absence survey for a particular species by a qualified biologist. The absence of listed species or known sightings in the databases does not necessarily indicate the site is clear and no listed species are present, it could be an indication that the site has not been previously surveyed. In addition, this review is not aimed at compliance with the Migratory Bird Treaty Act or the Bald and Golden Eagle Protection Act. 7.4 Historic Properties/Archaeological Resources Review A limited literature and agency file review was conducted to identify publicly available records of known occurrence of cultural resources on the site. Note that records pertaining to location of cultural resources are often restricted and not available to the public. Absence of records does not guarantee absence of cultural resources; it may be that a survey for the site has not previously been completed or that such records are not publicly available. This review is limited and does not constitute a site investigation by an archeologist or historian or concurrence from the State Historic Preservation Office (SHPO). Cultural resources are comprised of historic properties and archaeological artifacts. The review included the National Register of Historic Places and Freedom of Information Act (FOIA) and a Responsive ■ Resourceful ■ Reliable 19 Phase I Environmental Site Assessment Irerracon Approximate 15.14-Acre Site Bozeman, MT November 10, 2021 Terracon Project No. 26217114 review of publicly available information on the SHPO or State public database. Cultural resources or structures of historical significance were not documented on the National Register of Historic Places or in the publicly available information from the SHPO. Regardless of whether resources have or have not been identified on-site or adjacent, consultation with SHPO or the local regulating authority may be necessary to obtain concurrence for the site. Terracon Cultural Resources professionals can advise on applicability and as appropriate, submit a Cultural Resources Assessment Survey (CRAS) letter to SHPO or the local regulating authority. Please note that they may have 30 or more calendar days to review the request and may not respond if the request is not part of a permit request. It should be noted that Section 106 of the National Historic Preservation Act (NHPA) applies to federal undertakings. If federal funding or federal permitting is introduced to the project, the completion of a CRAS may be a requirement for meeting Section 106 obligations. 7.5 ASTM E 2600-10 Vapor Encroachment Screening Terracon conducted a Tier 1 Vapor Encroachment Screening (VES), in general accordance with the procedures included in ASTM E 2600-10, Standard Guide for Vapor Encroachment Screening on Property Involved in Real Estate Transactions. The purpose of the Tier 1 VIES is to evaluate whether a vapor encroachment condition (VEC) may be present at the site. A VEC is defined by ASTM as the "presence or likely presence of chemical(s) of concern (COC) vapors in the subsurface of the target property caused by the release of vapors from contaminated soil or groundwater or both either on or near the target property as identified by the Tier I procedures in the Guide." This purpose was pursued through use of information collected in conjunction with the ESA, including existing/planned use of the site, type of structures located on the site, surrounding property description, user information, historical and physical records review, regulatory database review, manmade or natural conduits, as applicable, and a visual noninvasive reconnaissance of the site and adjoining properties. Limitations, ASTM deviations, and significant gaps (if identified) are evident from reviewing the applicable scope of services and the Phase I report text. The scope of work for the Tier 1 VIES does not include regulatory file reviews (other than those performed as part of the Phase I ESA) or subsurface investigations to evaluate soil, soil gas, or groundwater quality, nor does it evaluate the potential for vapor intrusion into on-site structures or assess indoor air quality. 7.5.1 Existing / Planned Use of the Site/Structures The site is an approximately 15.14-acre property that is currently undeveloped. Future planned use is to construct an apartment building complex. Responsive ■ Resourceful ■ Reliable 20 Phase I Environmental Site Assessment Irerracon Approximate 15.14-Acre Site Bozeman, MT November 10, 2021 Terracon Project No. 26217114 7.5.2 Surrounding Area Description Please refer to Section 6.0. 7.5.3 User Specialized Knowledge Please refer to Section 1.6. 7.5.4 Regulatory Records Terracon reviewed the regulatory database (see Section 4.0) for facilities potentially utilizing petroleum hydrocarbons within one-tenth of a mile of the site and facilities potentially using other volatile chemicals of concern within one-third of a mile of the site. Based on Terracon's review of the regulatory records, Terracon did not identify potential facilities of concern. Although no facilities were identified in the regulatory databases, local area knowledge identified the Bozeman Solvent Site (BSS), associated with a former drycleaner, and is discussed in detail in Section 4.3. VECs were not identified in association with the Bozeman Solvent Site based on distance from the site and analytical data from monitoring wells located closer to the BSS. Based on Terracon's review of the regulatory records, VECs were not identified on the site associated with the identified potential facilities of concern. 7.5.5 Physical Setting Characteristics The site is located within Gallatin Valley and predominantly consists of alluvium of braid plains, characterized by well-rounded, well-sorted bouldery gravel and sand with some thin beds of clayey silt. Soils are identified by the NRCS as silt loam. Soils are well-drained and parent material consists of calcareous loess. The depth to groundwater is estimated to be 10-40 feet, and the direction of ground water flow is estimated to be north, toward the Gallatin River based on the observed topographic gradient. 7.5.6 Natural or Man-made Conduits The site, although itself undeveloped, is located in a developed area of the city containing utilities along the adjacent rights of way. Based on the absence of potential identified vapor sources in the site vicinity it is unlikely that man-made conduits, such as utility corridors, provide a potential path for vapor migration. Additionally, natural conduits, such as karst terrain/features, are not known to exist in the site vicinity.

They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http://www.nres.usda.gov/wps/ portal/nres/main/soils/health/)and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (https://offices.sc.egov.usda.gov/locator/app?agency=nres)or your NRCS State Soil Scientist(http://www.nres.usda.gov/wps/portal/nres/detail/soils/contactus/? cid=nres142p2_053951). Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations. The National Cooperative Soil Survey is a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey. Information about soils is updated periodically. Updated information is available through the NRCS Web Soil Survey, the site for official soil survey information.

They include a description of the soils and miscellaneous areas and their location on the landscape and tables that show soil properties and limitations affecting various uses. Soil scientists observed the steepness, length, and shape of the slopes; the general pattern of drainage; the kinds of crops and native plants; and the kinds of bedrock. They observed and described many soil profiles. A soil profile is the sequence of natural layers, or horizons, in a soil. The profile extends from the surface down into the unconsolidated material in which the soil formed or from the surface down to bedrock. The unconsolidated material is devoid of roots and other living organisms and has not been changed by other biological activity. Currently, soils are mapped according to the boundaries of major land resource areas (MLRAs). MLRAs are geographically associated land resource units that share common characteristics related to physiography, geology, climate, water resources, soils, biological resources, and land uses (USDA, 2006). Soil survey areas typically consist of parts of one or more MLRA. The soils and miscellaneous areas in a survey area occur in an orderly pattern that is related to the geology, landforms, relief, climate, and natural vegetation of the area. Each kind of soil and miscellaneous area is associated with a particular kind of landform or with a segment of the landform. By observing the soils and miscellaneous areas in the survey area and relating their position to specific segments of the landform, a soil scientist develops a concept, or model, of how they were formed. Thus, during mapping, this model enables the soil scientist to predict with a considerable degree of accuracy the kind of soil or miscellaneous area at a specific location on the landscape. Commonly, individual soils on the landscape merge into one another as their characteristics gradually change. To construct an accurate soil map, however, soil scientists must determine the boundaries between the soils. They can observe only a limited number of soil profiles. Nevertheless, these observations, supplemented by an understanding of the soil-vegetation-landscape relationship, are sufficient to verify predictions of the kinds of soil in an area and to determine the boundaries. Soil scientists recorded the characteristics of the soil profiles that they studied. They noted soil color, texture, size and shape of soil aggregates, kind and amount of rock fragments, distribution of plant roots, reaction, and other features that enable them to identify soils. After describing the soils in the survey area and determining their properties, the soil scientists assigned the soils to taxonomic classes (units). Taxonomic classes are concepts. Each taxonomic class has a set of soil characteristics with precisely defined limits. The classes are used as a basis for comparison to classify soils systematically. Soil taxonomy, the system of taxonomic classification used in the United States, is based mainly on the kind and character of soil properties and the arrangement of horizons within the profile. After the soil 5 Custom Soil Resource Report scientists classified and named the soils in the survey area, they compared the individual soils with similar soils in the same taxonomic class in other areas so that they could confirm data and assemble additional data based on experience and research. The objective of soil mapping is not to delineate pure map unit components; the objective is to separate the landscape into landforms or landform segments that have similar use and management requirements. Each map unit is defined by a unique combination of soil components and/or miscellaneous areas in predictable proportions. Some components may be highly contrasting to the other components of the map unit. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The delineation of such landforms and landform segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, onsite investigation is needed to define and locate the soils and miscellaneous areas. Soil scientists make many field observations in the process of producing a soil map. The frequency of observation is dependent upon several factors, including scale of mapping, intensity of mapping, design of map units, complexity of the landscape, and experience of the soil scientist. Observations are made to test and refine the soil-landscape model and predictions and to verify the classification of the soils at specific locations. Once the soil-landscape model is refined, a significantly smaller number of measurements of individual soil properties are made and recorded. These measurements may include field measurements, such as those for color, depth to bedrock, and texture, and laboratory measurements, such as those for content of sand, silt, clay, salt, and other components. Properties of each soil typically vary from one point to another across the landscape. Observations for map unit components are aggregated to develop ranges of characteristics for the components. The aggregated values are presented. Direct measurements do not exist for every property presented for every map unit component. Values for some properties are estimated from combinations of other properties. While a soil survey is in progress, samples of some of the soils in the area generally are collected for laboratory analyses and for engineering tests. Soil scientists interpret the data from these analyses and tests as well as the field-observed characteristics and the soil properties to determine the expected behavior of the soils under different uses. Interpretations for all of the soils are field tested through observation of the soils in different uses and under different levels of management. Some interpretations are modified to fit local conditions, and some new interpretations are developed to meet local needs. Data are assembled from other sources, such as research information, production records, and field experience of specialists. For example, data on crop yields under defined levels of management are assembled from farm records and from field or plot experiments on the same kinds of soil. Predictions about soil behavior are based not only on soil properties but also on such variables as climate and biological activity. Soil conditions are predictable over long periods of time, but they are not predictable from year to year. For example, soil scientists can predict with a fairly high degree of accuracy that a given soil will have a high water table within certain depths in most years, but they cannot predict that a high water table will always be at a specific level in the soil on a specific date. After soil scientists located and identified the significant natural bodies of soil in the survey area, they drew the boundaries of these bodies on aerial photographs and 6 Custom Soil Resource Report identified each as a specific map unit. Aerial photographs show trees, buildings, fields, roads, and rivers, all of which help in locating boundaries accurately. 7 Soil Map The soil map section includes the soil map for the defined area of interest, a list of soil map units on the map and extent of each map unit, and cartographic symbols displayed on the map. Also presented are various metadata about data used to produce the map, and a description of each soil map unit. 8 Custom Soil Resource Report 3 Soil Map N 'a M 494300 494400 494500 494600 494700 494800 45'4Z 7 N 45°42'7"N af�r•� 1. d - - C�C3 h �r 1 45'41'41"N 45'41'41"N 494300 494400 494500 494600 494700 494800 En 3 3 v Map Scale:1:3,890 i printed on A portrait(8.5"x 11")sheet.

The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. 11 Custom Soil Resource Report The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha-Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha-Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example. 12 Custom Soil Resource Report Gallatin County Area, Montana 5013—Blackdog silt loam, 0 to 4 percent slopes Map Unit Setting National map unit symbol: 56vq Elevation: 4,350 to 5,500 feet Mean annual precipitation: 15 to 19 inches Mean annual air temperature: 37 to 43 degrees F Frost-free period: 90 to 110 days Farmland classification: All areas are prime farmland Map Unit Composition Blackdog and similar soils: 90 percent Minor components: 10 percent Estimates are based on observations, descriptions, and transects of the mapunit.

ABC soil A soil having an A, a B, and a C horizon. Ablation till Loose, relatively permeable earthy material deposited during the downwasting of nearly static glacial ice, either contained within or accumulated on the surface of the glacier. AC soil A soil having only an A and a C horizon. Commonly, such soil formed in recent alluvium or on steep, rocky slopes. Aeration, soil The exchange of air in soil with air from the atmosphere. The air in a well aerated soil is similar to that in the atmosphere; the air in a poorly aerated soil is considerably higher in carbon dioxide and lower in oxygen. Aggregate, soil Many fine particles held in a single mass or cluster. Natural soil aggregates, such as granules, blocks, or prisms, are called peds. Clods are aggregates produced by tillage or logging. Alkali (sodic) soil A soil having so high a degree of alkalinity(pH 8.5 or higher)or so high a percentage of exchangeable sodium (15 percent or more of the total exchangeable bases), or both, that plant growth is restricted. Alluvial cone A semiconical type of alluvial fan having very steep slopes. It is higher, narrower, and steeper than a fan and is composed of coarser and thicker layers of material deposited by a combination of alluvial episodes and (to a much lesser degree) landslides (debris flow). The coarsest materials tend to be concentrated at the apex of the cone. 21 Custom Soil Resource Report Alluvial fan A low, outspread mass of loose materials and/or rock material, commonly with gentle slopes. It is shaped like an open fan or a segment of a cone. The material was deposited by a stream at the place where it issues from a narrow mountain valley or upland valley or where a tributary stream is near or at its junction with the main stream. The fan is steepest near its apex, which points upstream, and slopes gently and convexly outward (downstream)with a gradual decrease in gradient. Alluvium Unconsolidated material, such as gravel, sand, silt, clay, and various mixtures of these, deposited on land by running water. Alpha,alpha-dipyridyl A compound that when dissolved in ammonium acetate is used to detect the presence of reduced iron (Fe II) in the soil. A positive reaction implies reducing conditions and the likely presence of redoximorphic features. Animal unit month (AUM) The amount of forage required by one mature cow of approximately 1,000 pounds weight, with or without a calf, for 1 month. Aquic conditions Current soil wetness characterized by saturation, reduction, and redoximorphic features. Argillic horizon A subsoil horizon characterized by an accumulation of illuvial clay. Arroyo The flat-floored channel of an ephemeral stream, commonly with very steep to vertical banks cut in unconsolidated material. It is usually dry but can be transformed into a temporary watercourse or short-lived torrent after heavy rain within the watershed. Aspect The direction toward which a slope faces. Also called slope aspect. Association, soil A group of soils or miscellaneous areas geographically associated in a characteristic repeating pattern and defined and delineated as a single map unit. Available water capacity (available moisture capacity) The capacity of soils to hold water available for use by most plants. It is commonly defined as the difference between the amount of soil water at field moisture capacity and the amount at wilting point. It is commonly expressed as inches of water per inch of soil. The capacity, in inches, in a 60-inch profile or to a limiting layer is expressed as: 22 Custom Soil Resource Report Very low:0 to 3 Low:3 to 6 Moderate:6 to 9 High:9 to 12 Very high: More than 12 Backslope The position that forms the steepest and generally linear, middle portion of a hillslope. In profile, backslopes are commonly bounded by a convex shoulder above and a concave footslope below. Backswamp A flood-plain Iandform. Extensive, marshy or swampy, depressed areas of flood plains between natural levees and valley sides or terraces. Badland A landscape that is intricately dissected and characterized by a very fine drainage network with high drainage densities and short, steep slopes and narrow interfluves. Badlands develop on surfaces that have little or no vegetative cover overlying unconsolidated or poorly cemented materials (clays, silts, or sandstones)with, in some cases, soluble minerals, such as gypsum or halite. Bajada A broad, gently inclined alluvial piedmont slope extending from the base of a mountain range out into a basin and formed by the lateral coalescence of a series of alluvial fans. Typically, it has a broadly undulating transverse profile, parallel to the mountain front, resulting from the convexities of component fans. The term is generally restricted to constructional slopes of intermontane basins. Basal area The area of a cross section of a tree, generally referring to the section at breast height and measured outside the bark. It is a measure of stand density, commonly expressed in square feet. Base saturation The degree to which material having cation-exchange properties is saturated with exchangeable bases (sum of Ca, Mg, Na, and K), expressed as a percentage of the total cation-exchange capacity. Base slope (geomorphology) A geomorphic component of hills consisting of the concave to linear (perpendicular to the contour)slope that, regardless of the lateral shape, forms an apron or wedge at the bottom of a hillside dominated by colluvium and slope-wash sediments (for example, slope alluvium). Bedding plane A planar or nearly planar bedding surface that visibly separates each successive layer of stratified sediment or rock(of the same or different Iithology) 23 Custom Soil Resource Report from the preceding or following layer; a plane of deposition. It commonly marks a change in the circumstances of deposition and may show a parting, a color difference, a change in particle size, or various combinations of these. The term is commonly applied to any bedding surface, even one that is conspicuously bent or deformed by folding. Bedding system A drainage system made by plowing, grading, or otherwise shaping the surface of a flat field. It consists of a series of low ridges separated by shallow, parallel dead furrows. Bedrock The solid rock that underlies the soil and other unconsolidated material or that is exposed at the surface. Bedrock-controlled topography A landscape where the configuration and relief of the landforms are determined or strongly influenced by the underlying bedrock. Bench terrace A raised, level or nearly level strip of earth constructed on or nearly on a contour, supported by a barrier of rocks or similar material, and designed to make the soil suitable for tillage and to prevent accelerated erosion. Bisequum Two sequences of soil horizons, each of which consists of an illuvial horizon and the overlying eluvial horizons. Blowout (map symbol) A saucer-, cup-, or trough-shaped depression formed by wind erosion on a preexisting dune or other sand deposit, especially in an area of shifting sand or loose soil or where protective vegetation is disturbed or destroyed. The adjoining accumulation of sand derived from the depression, where recognizable, is commonly included. Blowouts are commonly small. Borrow pit (map symbol) An open excavation from which soil and underlying material have been removed, usually for construction purposes. Bottom land An informal term loosely applied to various portions of a flood plain. Boulders Rock fragments larger than 2 feet (60 centimeters) in diameter. Breaks A landscape or tract of steep, rough or broken land dissected by ravines and gullies and marking a sudden change in topography. 24 Custom Soil Resource Report Breast height An average height of 4.5 feet above the ground surface; the point on a tree where diameter measurements are ordinarily taken. Brush management Use of mechanical, chemical, or biological methods to make conditions favorable for reseeding or to reduce or eliminate competition from woody vegetation and thus allow understory grasses and forbs to recover. Brush management increases forage production and thus reduces the hazard of erosion. It can improve the habitat for some species of wildlife. Butte An isolated, generally flat-topped hill or mountain with relatively steep slopes and talus or precipitous cliffs and characterized by summit width that is less than the height of bounding escarpments; commonly topped by a caprock of resistant material and representing an erosion remnant carved from flat-lying rocks. Cable yarding A method of moving felled trees to a nearby central area for transport to a processing facility. Most cable yarding systems involve use of a drum, a pole, and wire cables in an arrangement similar to that of a rod and reel used for fishing. To reduce friction and soil disturbance, felled trees generally are reeled in while one end is lifted or the entire log is suspended. Calcareous soil A soil containing enough calcium carbonate (commonly combined with magnesium carbonate)to effervesce visibly when treated with cold, dilute hydrochloric acid. Caliche A general term for a prominent zone of secondary carbonate accumulation in surficial materials in warm, subhumid to and areas. Caliche is formed by both geologic and pedologic processes. Finely crystalline calcium carbonate forms a nearly continuous surface-coating and void-filling medium in geologic (parent) materials. Cementation ranges from weak in nonindurated forms to very strong in indurated forms. Other minerals (e.g., carbonates, silicate, and sulfate) may occur as accessory cements. Most petrocalcic horizons and some calcic horizons are caliche. California bearing ratio (CBR) The load-supporting capacity of a soil as compared to that of standard crushed limestone, expressed as a ratio. First standardized in California. A soil having a CBR of 16 supports 16 percent of the load that would be supported by standard crushed limestone, per unit area, with the same degree of distortion. Canopy The leafy crown of trees or shrubs. (See Crown.) 25 Custom Soil Resource Report Canyon A long, deep, narrow valley with high, precipitous walls in an area of high local relief. Capillary water Water held as a film around soil particles and in tiny spaces between particles. Surface tension is the adhesive force that holds capillary water in the soil. Catena A sequence, or"chain," of soils on a landscape that formed in similar kinds of parent material and under similar climatic conditions but that have different characteristics as a result of differences in relief and drainage. Cation An ion carrying a positive charge of electricity. The common soil cations are calcium, potassium, magnesium, sodium, and hydrogen. Cation-exchange capacity The total amount of exchangeable cations that can be held by the soil, expressed in terms of milliequivalents per 100 grams of soil at neutrality(pH 7.0)or at some other stated pH value. The term, as applied to soils, is synonymous with base-exchange capacity but is more precise in meaning. Catsteps See Terracettes. Cement rock Shaly limestone used in the manufacture of cement. Channery soil material Soil material that has, by volume, 15 to 35 percent thin, flat fragments of sandstone, shale, slate, limestone, or schist as much as 6 inches (15 centimeters) along the longest axis. A single piece is called a channer. Chemical treatment Control of unwanted vegetation through the use of chemicals. Chiseling Tillage with an implement having one or more soil-penetrating points that shatter or loosen hard, compacted layers to a depth below normal plow depth. Cirque A steep-walled, semicircular or crescent-shaped, half-bowl-like recess or hollow, commonly situated at the head of a glaciated mountain valley or high on the side of a mountain. It was produced by the erosive activity of a mountain glacier. It commonly contains a small round lake (tarn). 26 Custom Soil Resource Report Clay As a soil separate, the mineral soil particles less than 0.002 millimeter in diameter. As a soil textural class, soil material that is 40 percent or more clay, less than 45 percent sand, and less than 40 percent silt. Clay depletions See Redoximorphic features. Clay film A thin coating of oriented clay on the surface of a soil aggregate or lining pores or root channels. Synonyms: clay coating, clay skin. Clay spot(map symbol) A spot where the surface texture is silty clay or clay in areas where the surface layer of the soils in the surrounding map unit is sandy loam, loam, silt loam, or coarser. Claypan A dense, compact subsoil layer that contains much more clay than the overlying materials, from which it is separated by a sharply defined boundary. The layer restricts the downward movement of water through the soil. A claypan is commonly hard when dry and plastic and sticky when wet. Climax plant community The stabilized plant community on a particular site. The plant cover reproduces itself and does not change so long as the environment remains the same. Coarse textured soil Sand or loamy sand. Cobble (or cobblestone) A rounded or partly rounded fragment of rock 3 to 10 inches (7.6 to 25 centimeters) in diameter. Cobbly soil material Material that has 15 to 35 percent, by volume, rounded or partially rounded rock fragments 3 to 10 inches (7.6 to 25 centimeters) in diameter. Very cobbly soil material has 35 to 60 percent of these rock fragments, and extremely cobbly soil material has more than 60 percent. COLE (coefficient of linear extensibility) See Linear extensibility. Colluvium Unconsolidated, unsorted earth material being transported or deposited on side slopes and/or at the base of slopes by mass movement (e.g., direct gravitational action) and by local, unconcentrated runoff. 27 Custom Soil Resource Report Complex slope Irregular or variable slope. Planning or establishing terraces, diversions, and other water-control structures on a complex slope is difficult. Complex, soil A map unit of two or more kinds of soil or miscellaneous areas in such an intricate pattern or so small in area that it is not practical to map them separately at the selected scale of mapping. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Concretions See Redoximorphic features. Conglomerate A coarse grained, clastic sedimentary rock composed of rounded or subangular rock fragments more than 2 millimeters in diameter. It commonly has a matrix of sand and finer textured material. Conglomerate is the consolidated equivalent of gravel. Conservation cropping system Growing crops in combination with needed cultural and management practices. In a good conservation cropping system, the soil-improving crops and practices more than offset the effects of the soil-depleting crops and practices. Cropping systems are needed on all tilled soils. Soil-improving practices in a conservation cropping system include the use of rotations that contain grasses and legumes and the return of crop residue to the soil. Other practices include the use of green manure crops of grasses and legumes, proper tillage, adequate fertilization, and weed and pest control. Conservation tillage A tillage system that does not invert the soil and that leaves a protective amount of crop residue on the surface throughout the year. Consistence, soil Refers to the degree of cohesion and adhesion of soil material and its resistance to deformation when ruptured. Consistence includes resistance of soil material to rupture and to penetration; plasticity, toughness, and stickiness of puddled soil material; and the manner in which the soil material behaves when subject to compression. Terms describing consistence are defined in the "Soil Survey Manual." Contour striperopping Growing crops in strips that follow the contour. Strips of grass or close-growing crops are alternated with strips of clean-tilled crops or summer fallow. Control section The part of the soil on which classification is based. The thickness varies among different kinds of soil, but for many it is that part of the soil profile between depths of 10 inches and 40 or 80 inches. 28 Custom Soil Resource Report Coprogenous earth (sedimentary peat) A type of limnic layer composed predominantly of fecal material derived from aquatic animals. Corrosion (geomorphology) A process of erosion whereby rocks and soil are removed or worn away by natural chemical processes, especially by the solvent action of running water, but also by other reactions, such as hydrolysis, hydration, carbonation, and oxidation. Corrosion (soil survey interpretations) Soil-induced electrochemical or chemical action that dissolves or weakens concrete or uncoated steel. Cover crop A close-growing crop grown primarily to improve and protect the soil between periods of regular crop production, or a crop grown between trees and vines in orchards and vineyards. Crop residue management Returning crop residue to the soil, which helps to maintain soil structure, organic matter content, and fertility and helps to control erosion. Cropping system Growing crops according to a planned system of rotation and management practices. Cross-slope farming Deliberately conducting farming operations on sloping farmland in such a way that tillage is across the general slope. Crown The upper part of a tree or shrub, including the living branches and their foliage. Cryoturbate A mass of soil or other unconsolidated earthy material moved or disturbed by frost action. It is typically coarser than the underlying material. Cuesta An asymmetric ridge capped by resistant rock layers of slight or moderate dip (commonly less than 15 percent slopes); a type of homocline produced by differential erosion of interbedded resistant and weak rocks. A cuesta has a long, gentle slope on one side (dip slope)that roughly parallels the inclined beds; on the other side, it has a relatively short and steep or clifflike slope (scarp)that cuts through the tilted rocks. 29 Custom Soil Resource Report Culmination of the mean annual increment(CMAI) The average annual increase per acre in the volume of a stand. Computed by dividing the total volume of the stand by its age. As the stand increases in age, the mean annual increment continues to increase until mortality begins to reduce the rate of increase. The point where the stand reaches its maximum annual rate of growth is called the culmination of the mean annual increment. Cutbanks cave The walls of excavations tend to cave in or slough. Decreasers The most heavily grazed climax range plants. Because they are the most palatable, they are the first to be destroyed by overgrazing. Deferred grazing Postponing grazing or resting grazing land for a prescribed period. Delta A body of alluvium having a surface that is fan shaped and nearly flat; deposited at or near the mouth of a river or stream where it enters a body of relatively quiet water, generally a sea or lake. Dense layer A very firm, massive layer that has a bulk density of more than 1.8 grams per cubic centimeter. Such a layer affects the ease of digging and can affect filling and compacting. Depression, closed (map symbol) A shallow, saucer-shaped area that is slightly lower on the landscape than the surrounding area and that does not have a natural outlet for surface drainage. Depth, soil Generally, the thickness of the soil over bedrock. Very deep soils are more than 60 inches deep over bedrock; deep soils, 40 to 60 inches; moderately deep, 20 to 40 inches; shallow, 10 to 20 inches; and very shallow, less than 10 inches. Desert pavement A natural, residual concentration or layer of wind-polished, closely packed gravel, boulders, and other rock fragments mantling a desert surface. It forms where wind action and sheetwash have removed all smaller particles or where rock fragments have migrated upward through sediments to the surface. It typically protects the finer grained underlying material from further erosion. Diatomaceous earth A geologic deposit of fine, grayish siliceous material composed chiefly or entirely of the remains of diatoms. 30 Custom Soil Resource Report Dip slope A slope of the land surface, roughly determined by and approximately conforming to the dip of the underlying bedrock. Diversion (or diversion terrace) A ridge of earth, generally a terrace, built to protect downslope areas by diverting runoff from its natural course. Divided-slope farming A form of field striperopping in which crops are grown in a systematic arrangement of two strips, or bands, across the slope to reduce the hazard of water erosion. One strip is in a close-growing crop that provides protection from erosion, and the other strip is in a crop that provides less protection from erosion. This practice is used where slopes are not long enough to permit a full striperopping pattern to be used. Drainage class (natural) Refers to the frequency and duration of wet periods under conditions similar to those under which the soil formed. Alterations of the water regime by human activities, either through drainage or irrigation, are not a consideration unless they have significantly changed the morphology of the soil. Seven classes of natural soil drainage are recognized—excessively drained, somewhat excessively drained, well drained, moderately well drained, somewhat poorly drained, poorly drained, and very poorly drained. These classes are defined in the "Soil Survey Manual." Drainage, surface Runoff, or surface flow of water, from an area. Drainageway A general term for a course or channel along which water moves in draining an area. A term restricted to relatively small, linear depressions that at some time move concentrated water and either do not have a defined channel or have only a small defined channel. Draw A small stream valley that generally is shallower and more open than a ravine or gulch and that has a broader bottom. The present stream channel may appear inadequate to have cut the drainageway that it occupies. Drift A general term applied to all mineral material (clay, silt, sand, gravel, and boulders)transported by a glacier and deposited directly by or from the ice or transported by running water emanating from a glacier. Drift includes unstratified material (till)that forms moraines and stratified deposits that form outwash plains, eskers, kames, varves, and glaciofluvial sediments. The term is generally applied to Pleistocene glacial deposits in areas that no longer contain glaciers. 31 Custom Soil Resource Report Drumlin A low, smooth, elongated oval hill, mound, or ridge of compact till that has a core of bedrock or drift. It commonly has a blunt nose facing the direction from which the ice approached and a gentler slope tapering in the other direction. The longer axis is parallel to the general direction of glacier flow. Drumlins are products of streamline (laminar)flow of glaciers, which molded the subglacial floor through a combination of erosion and deposition. Duff A generally firm organic layer on the surface of mineral soils. It consists of fallen plant material that is in the process of decomposition and includes everything from the litter on the surface to underlying pure humus. Dune A low mound, ridge, bank, or hill of loose, windblown granular material (generally sand), either barren and capable of movement from place to place or covered and stabilized with vegetation but retaining its characteristic shape. Earthy fill See Mine spoil. Ecological site An area where climate, soil, and relief are sufficiently uniform to produce a distinct natural plant community. An ecological site is the product of all the environmental factors responsible for its development. It is typified by an association of species that differ from those on other ecological sites in kind and/or proportion of species or in total production. Eluviation The movement of material in true solution or colloidal suspension from one place to another within the soil. Soil horizons that have lost material through eluviation are eluvial; those that have received material are illuvial. Endosaturation A type of saturation of the soil in which all horizons between the upper boundary of saturation and a depth of 2 meters are saturated. Eolian deposit Sand-, silt-, or clay-sized clastic material transported and deposited primarily by wind, commonly in the form of a dune or a sheet of sand or loess. Ephemeral stream A stream, or reach of a stream, that flows only in direct response to precipitation. It receives no long-continued supply from melting snow or other source, and its channel is above the water table at all times. 32 Custom Soil Resource Report Episaturation A type of saturation indicating a perched water table in a soil in which saturated layers are underlain by one or more unsaturated layers within 2 meters of the surface. Erosion The wearing away of the land surface by water, wind, ice, or other geologic agents and by such processes as gravitational creep. Erosion (accelerated) Erosion much more rapid than geologic erosion, mainly as a result of human or animal activities or of a catastrophe in nature, such as a fire, that exposes the surface. Erosion (geologic) Erosion caused by geologic processes acting over long geologic periods and resulting in the wearing away of mountains and the building up of such landscape features as flood plains and coastal plains. Synonym: natural erosion. Erosion pavement A surficial lag concentration or layer of gravel and other rock fragments that remains on the soil surface after sheet or rill erosion or wind has removed the finer soil particles and that tends to protect the underlying soil from further erosion. Erosion surface A land surface shaped by the action of erosion, especially by running water. Escarpment A relatively continuous and steep slope or cliff breaking the general continuity of more gently sloping land surfaces and resulting from erosion or faulting. Most commonly applied to cliffs produced by differential erosion. Synonym: scarp. Escarpment, bedrock (map symbol) A relatively continuous and steep slope or cliff, produced by erosion or faulting, that breaks the general continuity of more gently sloping land surfaces. Exposed material is hard or soft bedrock. Escarpment, nonbedrock (map symbol) A relatively continuous and steep slope or cliff, generally produced by erosion but in some places produced by faulting, that breaks the continuity of more gently sloping land surfaces. Exposed earthy material is nonsoil or very shallow soil. Esker A long, narrow, sinuous, steep-sided ridge of stratified sand and gravel deposited as the bed of a stream flowing in an ice tunnel within or below the ice (subglacial) or between ice walls on top of the ice of a wasting glacier and left 33 Custom Soil Resource Report behind as high ground when the ice melted. Eskers range in length from less than a kilometer to more than 160 kilometers and in height from 3 to 30 meters. Extrusive rock Igneous rock derived from deep-seated molten matter(magma)deposited and cooled on the earth's surface. Fallow Cropland left idle in order to restore productivity through accumulation of moisture. Summer fallow is common in regions of limited rainfall where cereal grain is grown. The soil is tilled for at least one growing season for weed control and decomposition of plant residue. Fan remnant A general term for landforms that are the remaining parts of older fan landforms, such as alluvial fans, that have been either dissected or partially buried. Fertility, soil The quality that enables a soil to provide plant nutrients, in adequate amounts and in proper balance, for the growth of specified plants when light, moisture, temperature, tilth, and other growth factors are favorable. Fibric soil material (peat) The least decomposed of all organic soil material. Peat contains a large amount of well preserved fiber that is readily identifiable according to botanical origin. Peat has the lowest bulk density and the highest water content at saturation of all organic soil material.

Forest type A stand of trees similar in composition and development because of given physical and biological factors by which it may be differentiated from other stands. Fragipan A loamy, brittle subsurface horizon low in porosity and content of organic matter and low or moderate in clay but high in silt or very fine sand. A fragipan appears cemented and restricts roots. When dry, it is hard or very hard and has a higher bulk density than the horizon or horizons above. When moist, it tends to rupture suddenly under pressure rather than to deform slowly. Genesis, soil The mode of origin of the soil. Refers especially to the processes or soil-forming factors responsible for the formation of the solum, or true soil, from the unconsolidated parent material. Gilgai Commonly, a succession of microbasins and microknolls in nearly level areas or of microvalleys and microridges parallel with the slope. Typically, the microrelief of clayey soils that shrink and swell considerably with changes in moisture content.

Hill A generic term for an elevated area of the land surface, rising as much as 1,000 feet above surrounding lowlands, commonly of limited summit area and having a well defined outline. Slopes are generally more than 15 percent. The distinction between a hill and a mountain is arbitrary and may depend on local usage. Hillslope A generic term for the steeper part of a hill between its summit and the drainage line, valley flat, or depression floor at the base of a hill. Horizon, soil A layer of soil, approximately parallel to the surface, having distinct characteristics produced by soil-forming processes. In the identification of soil horizons, an uppercase letter represents the major horizons. Numbers or lowercase letters that follow represent subdivisions of the major horizons. An explanation of the subdivisions is given in the"Soil Survey Manual." The major horizons of mineral soil are as follows: 38 Custom Soil Resource Report O horizon:An organic layer of fresh and decaying plant residue. L horizon:A layer of organic and mineral limnic materials, including coprogenous earth (sedimentary peat), diatomaceous earth, and marl. A horizon:The mineral horizon at or near the surface in which an accumulation of humified organic matter is mixed with the mineral material. Also, a plowed surface horizon, most of which was originally part of a B horizon. E horizon:The mineral horizon in which the main feature is loss of silicate clay, iron, aluminum, or some combination of these. 8 horizon:The mineral horizon below an A horizon. The B horizon is in part a layer of transition from the overlying A to the underlying C horizon. The B horizon also has distinctive characteristics, such as (1) accumulation of clay, sesquioxides, humus, or a combination of these; (2) prismatic or blocky structure; (3) redder or browner colors than those in the A horizon; or(4)a combination of these. C horizon:The mineral horizon or layer, excluding indurated bedrock, that is little affected by soil-forming processes and does not have the properties typical of the overlying soil material. The material of a C horizon may be either like or unlike that in which the solum formed. If the material is known to differ from that in the solum, an Arabic numeral, commonly a 2, precedes the letter C. Cr horizon:Soft, consolidated bedrock beneath the soil. R layer: Consolidated bedrock beneath the soil. The bedrock commonly underlies a C horizon, but it can be directly below an A or a B horizon. M layer:A root-limiting subsoil layer consisting of nearly continuous, horizontally oriented, human-manufactured materials. IN layer. A layer of water within or beneath the soil. Humus The well decomposed, more or less stable part of the organic matter in mineral soils. Hydrologic soil groups Refers to soils grouped according to their runoff potential. The soil properties that influence this potential are those that affect the minimum rate of water infiltration on a bare soil during periods after prolonged wetting when the soil is not frozen. These properties include depth to a seasonal high water table, the infiltration rate, and depth to a layer that significantly restricts the downward movement of water. The slope and the kind of plant cover are not considered but are separate factors in predicting runoff. Igneous rock Rock that was formed by cooling and solidification of magma and that has not been changed appreciably by weathering since its formation. Major varieties include plutonic and volcanic rock (e.g., andesite, basalt, and granite). Illuviation The movement of soil material from one horizon to another in the soil profile. Generally, material is removed from an upper horizon and deposited in a lower horizon. 39 Custom Soil Resource Report Impervious soil A soil through which water, air, or roots penetrate slowly or not at all. No soil is absolutely impervious to air and water all the time. Increasers Species in the climax vegetation that increase in amount as the more desirable plants are reduced by close grazing. Increasers commonly are the shorter plants and the less palatable to livestock. Infiltration The downward entry of water into the immediate surface of soil or other material, as contrasted with percolation, which is movement of water through soil layers or material. Infiltration capacity The maximum rate at which water can infiltrate into a soil under a given set of conditions. Infiltration rate The rate at which water penetrates the surface of the soil at any given instant, usually expressed in inches per hour. The rate can be limited by the infiltration capacity of the soil or the rate at which water is applied at the surface. Intake rate The average rate of water entering the soil under irrigation. Most soils have a fast initial rate; the rate decreases with application time. Therefore, intake rate for design purposes is not a constant but is a variable depending on the net irrigation application. The rate of water intake, in inches per hour, is expressed as follows: Very low: Less than 0.2 Low:0.2 to 0.4 Moderately low:0.4 to 0.75 Moderate:0.75 to 1.25 Moderately high: 1.25 to 1.75 High: 1.75 to 2.5 Very high: More than 2.5 Interfluve A landform composed of the relatively undissected upland or ridge between two adjacent valleys containing streams flowing in the same general direction. An elevated area between two drainageways that sheds water to those drainageways. Interfluve (geomorphology) A geomorphic component of hills consisting of the uppermost, comparatively level or gently sloping area of a hill; shoulders of backwearing hillslopes can narrow the upland or can merge, resulting in a strongly convex shape. 40 Custom Soil Resource Report Intermittent stream A stream, or reach of a stream, that does not flow year-round but that is commonly dry for 3 or more months out of 12 and whose channel is generally below the local water table. It flows only during wet periods or when it receives ground-water discharge or long, continued contributions from melting snow or other surface and shallow subsurface sources. Invaders On range, plants that encroach into an area and grow after the climax vegetation has been reduced by grazing. Generally, plants invade following disturbance of the surface. Iron depletions See Redoximorphic features. Irrigation Application of water to soils to assist in production of crops. Methods of irrigation are: Basin:Water is applied rapidly to nearly level plains surrounded by levees or dikes. Border:Water is applied at the upper end of a strip in which the lateral flow of water is controlled by small earth ridges called border dikes, or borders. Controlled flooding:Water is released at intervals from closely spaced field ditches and distributed uniformly over the field. Corrugation:Water is applied to small, closely spaced furrows or ditches in fields of close-growing crops or in orchards so that it flows in only one direction. Drip (or trickle):Water is applied slowly and under low pressure to the surface of the soil or into the soil through such applicators as emitters, porous tubing, or perforated pipe. Furrow:Water is applied in small ditches made by cultivation implements. Furrows are used for tree and row crops. Sprinkler:Water is sprayed over the soil surface through pipes or nozzles from a pressure system. Subirrigation:Water is applied in open ditches or tile lines until the water table is raised enough to wet the soil. Wild flooding:Water, released at high points, is allowed to flow onto an area without controlled distribution. Kame A low mound, knob, hummock, or short irregular ridge composed of stratified sand and gravel deposited by a subglacial stream as a fan or delta at the margin of a melting glacier; by a supraglacial stream in a low place or hole on the surface of the glacier; or as a ponded deposit on the surface or at the margin of stagnant ice. 41 Custom Soil Resource Report Karst (topography) A kind of topography that formed in limestone, gypsum, or other soluble rocks by dissolution and that is characterized by closed depressions, sinkholes, caves, and underground drainage.

Linear extensibility Refers to the change in length of an unconfined clod as moisture content is decreased from a moist to a dry state. Linear extensibility is used to determine the shrink-swell potential of soils. It is an expression of the volume change between the water content of the clod at 1/3-or 1/10-bar tension (33kPa or 10kPa tension) and oven dryness. Volume change is influenced by the amount and type of clay minerals in the soil. The volume change is the percent change for the whole soil.

Redoximorphic concentrations See Redoximorphic features. Redoximorphic depletions See Redoximorphic features. Redoximorphic features Redoximorphic features are associated with wetness and result from alternating periods of reduction and oxidation of iron and manganese compounds in the soil. Reduction occurs during saturation with water, and oxidation occurs when the soil is not saturated. Characteristic color patterns are created by these processes. The reduced iron and manganese ions may be removed from a soil if vertical or lateral fluxes of water occur, in which case there is no iron or manganese precipitation in that soil. Wherever the iron and manganese are oxidized and precipitated, they form either soft masses or hard concretions or nodules. Movement of iron and manganese as a result of redoximorphic processes in a soil may result in redoximorphic features that are defined as follows: 50 Custom Soil Resource Report 1. Redoximorphic concentrations.—These are zones of apparent accumulation of iron-manganese oxides, including: A. Nodules and concretions, which are cemented bodies that can be removed from the soil intact. Concretions are distinguished from nodules on the basis of internal organization. A concretion typically has concentric layers that are visible to the naked eye. Nodules do not have visible organized internal structure; and B. Masses, which are noncemented concentrations of substances within the soil matrix; and C. Pore linings, i.e., zones of accumulation along pores that may be either coatings on pore surfaces or impregnations from the matrix adjacent to the pores. 2. Redoximorphic depletions.—These are zones of low chroma (chromas less than those in the matrix)where either iron-manganese oxides alone or both iron-manganese oxides and clay have been stripped out, including: A. Iron depletions, i.e., zones that contain low amounts of iron and manganese oxides but have a clay content similar to that of the adjacent matrix; and B. Clay depletions, i.e., zones that contain low amounts of iron, manganese, and clay(often referred to as silt coatings or skeletans). 3.

Terms describing saturated hydraulic conductivity are: Very high: 100 or more micrometers per second (14.17 or more inches per hour) High: 10 to 100 micrometers per second (1.417 to 14.17 inches per hour) Moderately high: 1 to 10 micrometers per second (0.1417 inch to 1.417 inches per hour) Moderately low:0.1 to 1 micrometer per second (0.01417 to 0.1417 inch per hour) Low:0.01 to 0.1 micrometer per second (0.001417 to 0.01417 inch per hour) Very low: Less than 0.01 micrometer per second (less than 0.001417 inch per hour). To convert inches per hour to micrometers per second, multiply inches per hour by 7.0572. To convert micrometers per second to inches per hour, multiply micrometers per second by 0.1417. Saturation Wetness characterized by zero or positive pressure of the soil water. Under conditions of saturation, the water will flow from the soil matrix into an unlined auger hole. Scarification The act of abrading, scratching, loosening, crushing, or modifying the surface to increase water absorption or to provide a more tillable soil. Sedimentary rock A consolidated deposit of clastic particles, chemical precipitates, or organic remains accumulated at or near the surface of the earth under normal low temperature and pressure conditions. Sedimentary rocks include consolidated equivalents of alluvium, colluvium, drift, and eolian, lacustrine, and marine deposits. Examples are sandstone, siltstone, mudstone, claystone, shale, conglomerate, limestone, dolomite, and coal. 53 Custom Soil Resource Report Sequum A sequence consisting of an illuvial horizon and the overlying eluvial horizon. (See Eluviation.) Series, soil A group of soils that have profiles that are almost alike, except for differences in texture of the surface layer. All the soils of a series have horizons that are similar in composition, thickness, and arrangement. Severely eroded spot (map symbol) An area where, on the average, 75 percent or more of the original surface layer has been lost because of accelerated erosion. Not used in map units in which "severely eroded," "very severely eroded," or"gullied" is part of the map unit name. Shale Sedimentary rock that formed by the hardening of a deposit of clay, silty clay, or silty clay loam and that has a tendency to split into thin layers. Sheet erosion The removal of a fairly uniform layer of soil material from the land surface by the action of rainfall and surface runoff. Short, steep slope (map symbol) A narrow area of soil having slopes that are at least two slope classes steeper than the slope class of the surrounding map unit. Shoulder The convex, erosional surface near the top of a hillslope. A shoulder is a transition from summit to backslope. Shrink-swell The shrinking of soil when dry and the swelling when wet. Shrinking and swelling can damage roads, dams, building foundations, and other structures. It can also damage plant roots. Shrub-coppice dune A small, streamlined dune that forms around brush and clump vegetation. Side slope (geomorphology) A geomorphic component of hills consisting of a laterally planar area of a hillside. The overland waterflow is predominantly parallel. Side slopes are dominantly colluvium and slope-wash sediments. Silica A combination of silicon and oxygen. The mineral form is called quartz. 54 Custom Soil Resource Report Silica-sesquioxide ratio The ratio of the number of molecules of silica to the number of molecules of alumina and iron oxide. The more highly weathered soils or their clay fractions in warm-temperate, humid regions, and especially those in the tropics, generally have a low ratio. Silt As a soil separate, individual mineral particles that range in diameter from the upper limit of clay (0.002 millimeter)to the lower limit of very fine sand (0.05 millimeter). As a soil textural class, soil that is 80 percent or more silt and less than 12 percent clay. Siltstone An indurated silt having the texture and composition of shale but lacking its fine lamination or fissility; a massive mudstone in which silt predominates over clay. Similar soils Soils that share limits of diagnostic criteria, behave and perform in a similar manner, and have similar conservation needs or management requirements for the major land uses in the survey area. Sinkhole (map symbol) A closed, circular or elliptical depression, commonly funnel shaped, characterized by subsurface drainage and formed either by dissolution of the surface of underlying bedrock (e.g., limestone, gypsum, or salt)or by collapse of underlying caves within bedrock. Complexes of sinkholes in carbonate-rock terrain are the main components of karst topography. Site index A designation of the quality of a forest site based on the height of the dominant stand at an arbitrarily chosen age. For example, if the average height attained by dominant and codominant trees in a fully stocked stand at the age of 50 years is 75 feet, the site index is 75. Slickensides (pedogenic) Grooved, striated, and/or glossy(shiny) slip faces on structural peds, such as wedges; produced by shrink-swell processes, most commonly in soils that have a high content of expansive clays. Slide or slip (map symbol) A prominent landform scar or ridge caused by fairly recent mass movement or descent of earthy material resulting from failure of earth or rock under shear stress along one or several surfaces. Slope The inclination of the land surface from the horizontal. Percentage of slope is the vertical distance divided by horizontal distance, then multiplied by 100. Thus, a slope of 20 percent is a drop of 20 feet in 100 feet of horizontal distance. 55 Custom Soil Resource Report Slope alluvium Sediment gradually transported down the slopes of mountains or hills primarily by nonchannel alluvial processes (i.e., slope-wash processes)and characterized by particle sorting. Lateral particle sorting is evident on long slopes. In a profile sequence, sediments may be distinguished by differences in size and/or specific gravity of rock fragments and may be separated by stone lines. Burnished peds and sorting of rounded or subrounded pebbles or cobbles distinguish these materials from unsorted colluvial deposits. Slow refill The slow filling of ponds, resulting from restricted water transmission in the soil. Slow water movement Restricted downward movement of water through the soil. See Saturated hydraulic conductivity. Sodic (alkali) soil A soil having so high a degree of alkalinity (pH 8.5 or higher)or so high a percentage of exchangeable sodium (15 percent or more of the total exchangeable bases), or both, that plant growth is restricted. Sodic spot(map symbol) An area where the surface layer has a sodium adsorption ratio that is at least 10 more than that of the surface layer of the named soils in the surrounding map unit. The surface layer of the surrounding soils has a sodium adsorption ratio of 5 or less. Sodicity The degree to which a soil is affected by exchangeable sodium. Sodicity is expressed as a sodium adsorption ratio (SAR) of a saturation extract, or the ratio of Na+to Ca++ + Mg++. The degrees of sodicity and their respective ratios are: Slight: Less than 13:1 Moderate: 13-30:1 Strong: More than 30:1 Sodium adsorption ratio (SAR) A measure of the amount of sodium (Na) relative to calcium (Ca) and magnesium (Mg) in the water extract from saturated soil paste. It is the ratio of the Na concentration divided by the square root of one-half of the Ca + Mg concentration. Soft bedrock Bedrock that can be excavated with trenching machines, backhoes, small rippers, and other equipment commonly used in construction. 56 Custom Soil Resource Report Soil A natural, three-dimensional body at the earth's surface. It is capable of supporting plants and has properties resulting from the integrated effect of climate and living matter acting on earthy parent material, as conditioned by relief and by the passage of time. Soil separates Mineral particles less than 2 millimeters in equivalent diameter and ranging between specified size limits. The names and sizes, in millimeters, of separates recognized in the United States are as follows: Very coarse sand:2.0 to 1.0 Coarse sand: 1.0 to 0.5 Medium sand:0.5 to 0.25 Fine sand:0.25 to 0.10 Very fine sand:0.10 to 0.05 Silt:0.05 to 0.002 Clay: Less than 0.002 Solum The upper part of a soil profile, above the C horizon, in which the processes of soil formation are active. The solum in soil consists of the A, E, and B horizons. Generally, the characteristics of the material in these horizons are unlike those of the material below the solum. The living roots and plant and animal activities are largely confined to the solum. Spoil area (map symbol) A pile of earthy materials, either smoothed or uneven, resulting from human activity. Stone line In a vertical cross section, a line formed by scattered fragments or a discrete layer of angular and subangular rock fragments (commonly a gravel- or cobble- sized lag concentration)that formerly was draped across a topographic surface and was later buried by additional sediments. A stone line generally caps material that was subject to weathering, soil formation, and erosion before burial. Many stone lines seem to be buried erosion pavements, originally formed by sheet and rill erosion across the land surface. Stones Rock fragments 10 to 24 inches (25 to 60 centimeters) in diameter if rounded or 15 to 24 inches (38 to 60 centimeters) in length if flat. Stony Refers to a soil containing stones in numbers that interfere with or prevent tillage. 57 Custom Soil Resource Report Stony spot (map symbol) A spot where 0.01 to 0.1 percent of the soil surface is covered by rock fragments that are more than 10 inches in diameter in areas where the surrounding soil has no surface stones. Strath terrace A type of stream terrace; formed as an erosional surface cut on bedrock and thinly mantled with stream deposits (alluvium). Stream terrace One of a series of platforms in a stream valley, flanking and more or less parallel to the stream channel, originally formed near the level of the stream; represents the remnants of an abandoned flood plain, stream bed, or valley floor produced during a former state of fluvial erosion or deposition. Striperopping Growing crops in a systematic arrangement of strips or bands that provide vegetative barriers to wind erosion and water erosion. Structure, soil The arrangement of primary soil particles into compound particles or aggregates. The principal forms of soil structure are: Platy: Flat and laminated Prismatic:Vertically elongated and having flat tops Columnar:Vertically elongated and having rounded tops Angular blocky: Having faces that intersect at sharp angles (planes) Subangular blocky: Having subrounded and planar faces (no sharp angles) Granular:Small structural units with curved or very irregular faces Structureless soil horizons are defined as follows: Single grained: Entirely noncoherent(each grain by itself), as in loose sand Massive: Occurring as a coherent mass Stubble mulch Stubble or other crop residue left on the soil or partly worked into the soil. It protects the soil from wind erosion and water erosion after harvest, during preparation of a seedbed for the next crop, and during the early growing period of the new crop. Subsoil Technically, the B horizon; roughly, the part of the solum below plow depth. Subsoiling Tilling a soil below normal plow depth, ordinarily to shatter a hardpan or claypan. 58 Custom Soil Resource Report Substratum The part of the soil below the solum. Subsurface layer Any surface soil horizon (A, E, AB, or EB) below the surface layer. Summer fallow The tillage of uncropped land during the summer to control weeds and allow storage of moisture in the soil for the growth of a later crop. A practice common in semiarid regions, where annual precipitation is not enough to produce a crop every year. Summer fallow is frequently practiced before planting winter grain. Summit The topographically highest position of a hillslope. It has a nearly level (planar or only slightly convex)surface. Surface layer The soil ordinarily moved in tillage, or its equivalent in uncultivated soil, ranging in depth from 4 to 10 inches (10 to 25 centimeters). Frequently designated as the "plow layer," or the "Ap horizon." Surface soil The A, E, AB, and EB horizons, considered collectively. It includes all subdivisions of these horizons. Talus Rock fragments of any size or shape (commonly coarse and angular)derived from and lying at the base of a cliff or very steep rock slope. The accumulated mass of such loose broken rock formed chiefly by falling, rolling, or sliding. Taxadjuncts Soils that cannot be classified in a series recognized in the classification system. Such soils are named for a series they strongly resemble and are designated as taxadjuncts to that series because they differ in ways too small to be of consequence in interpreting their use and behavior. Soils are recognized as taxadjuncts only when one or more of their characteristics are slightly outside the range defined for the family of the series for which the soils are named. Terminal moraine An end moraine that marks the farthest advance of a glacier. It typically has the form of a massive arcuate or concentric ridge, or complex of ridges, and is underlain by till and other types of drift. Terrace (conservation) An embankment, or ridge, constructed across sloping soils on the contour or at a slight angle to the contour. The terrace intercepts surface runoff so that water soaks into the soil or flows slowly to a prepared outlet. A terrace in a field 59 Custom Soil Resource Report generally is built so that the field can be farmed. A terrace intended mainly for drainage has a deep channel that is maintained in permanent sod. Terrace (geomorphology) A steplike surface, bordering a valley floor or shoreline, that represents the former position of a flood plain, lake, or seashore. The term is usually applied both to the relatively flat summit surface (tread)that was cut or built by stream or wave action and to the steeper descending slope (scarp or riser)that has graded to a lower base level of erosion. Terracettes Small, irregular steplike forms on steep hillslopes, especially in pasture, formed by creep or erosion of surficial materials that may be induced or enhanced by trampling of livestock, such as sheep or cattle. Texture, soil The relative proportions of sand, silt, and clay particles in a mass of soil. The basic textural classes, in order of increasing proportion of fine particles, are sand, loamy sand, sandy loam, loam, silt loam, silt, sandy clay loam, clay loam, silty clay loam, sandy clay, silty clay, and clay. The sand, loamy sand, and sandy loam classes may be further divided by specifying "coarse," "fine,"or "very fine." Thin layer Otherwise suitable soil material that is too thin for the specified use. Till Dominantly unsorted and nonstratified drift, generally unconsolidated and deposited directly by a glacier without subsequent reworking by meltwater, and consisting of a heterogeneous mixture of clay, silt, sand, gravel, stones, and boulders; rock fragments of various lithologies are embedded within a finer matrix that can range from clay to sandy loam. Till plain An extensive area of level to gently undulating soils underlain predominantly by till and bounded at the distal end by subordinate recessional or end moraines. Tilth, soil The physical condition of the soil as related to tillage, seedbed preparation, seedling emergence, and root penetration. Toeslope The gently inclined surface at the base of a hillslope. Toeslopes in profile are commonly gentle and linear and are constructional surfaces forming the lower part of a hillslope continuum that grades to valley or closed-depression floors. 60 Custom Soil Resource Report Topsoil The upper part of the soil, which is the most favorable material for plant growth. It is ordinarily rich in organic matter and is used to topdress roadbanks, lawns, and land affected by mining. Trace elements Chemical elements, for example, zinc, cobalt, manganese, copper, and iron, in soils in extremely small amounts. They are essential to plant growth. Tread The flat to gently sloping, topmost, laterally extensive slope of terraces, flood- plain steps, or other stepped landforms; commonly a recurring part of a series of natural steplike Iandforms, such as successive stream terraces. Tuff A generic term for any consolidated or cemented deposit that is 50 percent or more volcanic ash. Upland An informal, general term for the higher ground of a region, in contrast with a low-lying adjacent area, such as a valley or plain, or for land at a higher elevation than the flood plain or low stream terrace; land above the footslope zone of the hillslope continuum. Valley fill The unconsolidated sediment deposited by any agent(water, wind, ice, or mass wasting) so as to fill or partly fill a valley. Variegation Refers to patterns of contrasting colors assumed to be inherited from the parent material rather than to be the result of poor drainage. Varve A sedimentary layer or a lamina or sequence of laminae deposited in a body of still water within a year. Specifically, a thin pair of graded glaciolacustrine layers seasonally deposited, usually by meltwater streams, in a glacial lake or other body of still water in front of a glacier. Very stony spot (map symbol) A spot where 0.1 to 3.0 percent of the soil surface is covered by rock fragments that are more than 10 inches in diameter in areas where the surface of the surrounding soil is covered by less than 0.01 percent stones. Water bars Smooth, shallow ditches or depressional areas that are excavated at an angle across a sloping road. They are used to reduce the downward velocity of water and divert it off and away from the road surface. Water bars can easily be driven over if constructed properly. 61 Custom Soil Resource Report Weathering All physical disintegration, chemical decomposition, and biologically induced changes in rocks or other deposits at or near the earth's surface by atmospheric or biologic agents or by circulating surface waters but involving essentially no transport of the altered material. Well graded Refers to soil material consisting of coarse grained particles that are well distributed over a wide range in size or diameter. Such soil normally can be easily increased in density and bearing properties by compaction. Contrasts with poorly graded soil. Wet spot (map symbol) A somewhat poorly drained to very poorly drained area that is at least two drainage classes wetter than the named soils in the surrounding map unit. Wilting point(or permanent wilting point) The moisture content of soil, on an ovendry basis, at which a plant(specifically a sunflower)wilts so much that it does not recover when placed in a humid, dark chamber. Windthrow The uprooting and tipping over of trees by the wind. 62 Wtional Wetlands InventoryProject #26217114 �, fit.-lt• c-� • ' y' �, 41" t - P,41 y r r- � •I w 1:7,218 0 0.05 0.1 0.2 mi (' � 'Sburce:Esri,Maxar,GeoEye,Earthstar Geographi4s,CN Aer the October 27,2021 This map is for general reference only.The US Fish and Wildlife Service is not responsible for the accuracy or currentness of the Wetlands base data shown on this map.All wetlands related data should Freshwater Emergent Wetland Lake be used in accordance with the layer metadata found on the Estuarine and Marine Dee water Wetlands Mapper web site.

Additionally, there is a report available from The Montana Natural Heritage Program (MTNHP)regarding the new wetland mapping titled"Wetlands of the Gallatin Valley: Change and Ecological Functions". http://mtnhp.org/Reports/Gallatin_Chanize_Revised.pdf Classification(Cowardin wetlands, riparian, uplands, hydrogeomorphic, etc.): Cowardin wetlands classification(Cowardin et al. 1979) FGDC Wetlands Mapping Standard(FGDC Wetlands Subcommittee, 2009) USFWS System for Mapping Riparian Areas in the Western US (USFWS 2009) Hydrogeomorphic (HGM) coding modified from Tiner(2003) No uplands classification. Data Limitations: Regional convention limits attribution of wetlands polygons to the class level and restricts the use of modifiers to one water regime and one special modifier. Mono-interpretation of imagery may have resulted in the misinterpretation of land cover types. General description of the Project Area: • Geography: The study area includes portions of Broadwater, Jefferson, Madison, and Gallatin Counties and is in the Middle Rockies Level III Ecoregion(Omernik 1987). Elevation ranges from 4,000 feet(1,219 meters) in the valley bottom near Logan to 9,012 feet(2,747 meters) in the Tobacco Root Mountains. The area is characterized by wide intermontane valleys and several mountain ranges. Geology of the project area is complex. The majority of the project area is comprised of large river valleys that are primarily formed in Tertiary sediments and Quaternary alluvial deposits (Nesser et al. 1997). Mountain ranges in the area were largely formed in mixed sedimentary or metasedimentary bedrock, with the exception of the Gallatin Mountains in the southeastern portion of the project area, which were formed in Tertiary volcanic flows and associated pyroclastic deposits consisting of rhyolite,basalt, and andesite. • Climate: Regional climate is influenced by continental air masses with cold, sunny, and dry winters and warm, dry summers. In the valley bottoms around Bozeman, average yearly maximum temperature is 55.2°F (12.9°C) and average yearly minimum temperature is 31.2 °F (44 °C). The warmest months are July and August. Average annual precipitation is 18.4 inches (467 mm). A third of the yearly precipitation occurs during April, May, and June. Average total snowfall is 85 inches (2,159 mm; Western Regional Climate Center 2009). • Vegetation, soils, and land use: Montane portions of the project area are dominated by coniferous forests. Higher elevation forests are comprised of whitebark pine (Pinus albicaulis), subalpine fir(Abies lasiocarpa), Engelmann spruce (Picea engelmannii), and lodgepole pine (Pinus contorta). Middle and lower elevation forests are dominated by Douglas-fir(Pseudotsuga menziesii) and lodgepole pine. Limber pine (Pinus flexilis) and Rocky Mountain juniper(Juniperus scopulorum) are locally common on calcareous substrates. Quaking aspen(Populus tremuloides) occurs in stands throughout the project area in sites where adequate soil moisture is available. Foothills and valleys are largely grassland and shrubland. Mountain big sagebrush (Artemisia tridentata ssp. vaseyana) is the dominant shrub, although stands of threetip sagebrush(A. tripartita) and basin big sagebrush (A. t. ssp. tridentata) are locally common. Alkaline or saline sites may support stands of greasewood(Sarcobatus vermiculatus). Bunchgrasses dominate the herbaceous layer, including bluebunch wheatgrass (Pseudoroegneria spicata), Idaho fescue (Festuca idahoensis), needle and thread(Hesperostipa comata), Sandberg's bluegrass (Poa secunda), and blue grama (Bouteloua gracilis). Soils are largely composed of borolls, orthents, and fluvents in the foothills and valley bottoms; soils within major floodplains are comprised of aquolls and aquents (McNab and Avers 1994). These soils are typically moderately deep to deep with loamy to clayey textures. Mountains are mostly ochrepts,boralfs, and borolls. Soils are shallow to moderately deep with loamy to sandy textures. Land uses include livestock and crop agriculture in the valleys and timber harvest in the mountains (McNab and Avers 1994). • Natural history or important cultural features: The Gallatin Valley and surrounding area was used by several Native American tribes as prime hunting grounds (Smith 1996). Lewis and Clark explored the area in 1805 (Smith 1996). The Jefferson, Madison, and Beaverhead Rivers converge near Three Forks, Montana to form the Missouri River. Description of wetland habitats: • Wetland classification codes and corresponding community type(s): From Jones 2004 unless otherwise noted. PFO: Palustrine forested wetlands are dominated by black cottonwood(Populus balsamifera). Cottonwood stands vary from open woodlands to closed canopy forests. Some areas along the lower reaches of the Jefferson, Madison, and Gallatin Rivers still have cottonwood recruitment, although the shrub layer has been lost in many areas. For those floodplains with a well- developed shrub layer, yellow willow (Salix lutea), redosier dogwood(Cornus sericea), and common chokecherry(Prunus virginiana) are found. PSS: Palustrine scrub-shrub wetlands occur on terraces along the floodplains of both low and high gradient streams and rivers. They can also be found around beaver ponds and on the fringes of fens and lakes. Common willow species at higher elevations include planeleaf willow(Salix planifolia) and Wolf s willow (S. wolfii). At middle elevations, Drummond's willow (S. drummondiana), Geyer willow (S. geyeriana), and Booth's willow (S. boothii) are common. At lower elevations, yellow willow and sandbar willow (S. exigua) occur along floodplains and on active gravel bars. Other common shrub species include gray alder(Alnus incana) and common chokecherry. PEM: Palustrine emergent wetlands are found in a variety of settings with several sedge species dominant, including woollyfruit sedge (Carex lasiocarpa),Northwest Territory sedge (C. utriculata), inflated sedge (C. vesicaria), and mud sedge (C. limosa) occurring on the wettest sites and native grasses such as tufted hairgrass (Deschampsia cespitosa) and bluejoint reedgrass (Calamagrostis canadensis) common on wet meadow sites. These wet meadow communities have been greatly impacted by livestock and other agricultural practices and are largely dominated by non-native grasses, particularly Kentucky bluegrass (Poa pratensis), smooth brome(Bromus inermis), common timothy(Phleum pratense), redtop (Agrostis gigantea), and reed canarygrass (Phalaris arundinacea). PAB, L2AB, R2AB: Aquatic bed wetlands occur in littoral (<2 meters in depth) and limnetic (> 2 meters in depth) zones of ponds and lakes or on the beds of slow-moving perennial streams. Common aquatic plant species include the floating-leaved yellow pond lily(Nuphar polysepalum), submerged or partially submerged species such as water milfoil (Myriophyllum spp.), common mare's-tail (Hippuris vulgaris), and pondweeds (Potamogeton spp.). Description of other habitats: • Riparian: Riparian forests are comprised largely of black cottonwood. Riparian scrub-shrub areas on high gradient streams are dominated by redosier dogwood, common chokecherry, western snowberry(Symphoricarpos occidentalis), and Wood's rose (Rosa woodsii). On low gradient streams, willows are common. The herbaceous layer is largely dominated by non- native pasture grasses,particularly Kentucky bluegrass (Poa pratensis), smooth brome (Bromus inermis), and common timothy(Phleum pretense). Higher elevation streams are dominated by Engelmann spruce, subalpine fir, and quaking aspen. • Uplands: Montane portions of the project area are dominated by coniferous forests with whitebark pine, subalpine fir, Engelmann spruce, and lodgepole pine at higher elevation and Douglas-fir and lodgepole pine common at middle and lower elevations. Quaking aspen occurs in stands throughout the project area on sites where adequate soil moisture is available. Foothills and valleys are largely grassland and shrubland. Shrublands are largely comprised of sagebrush species. Alkaline or saline sites may support stands of greasewood. Bunchgrasses dominate the herbaceous layer, including bluebunch wheatgrass, Idaho fescue, needle and thread, Sandberg's bluegrass, and blue grama.

The list may also include trust resources that occur outside of the project area, but that could potentially be directly or indirectly affected by activities in the project area. However, determining the likelihood and extent of effects a project may have on trust resources typically requires gathering additional site-specific (e.g., vegetation/species surveys) and project-specific (e.g., magnitude and timing of proposed activities) information. Below is a summary of the project information you provided and contact information for the USFWS office(s)with jurisdiction in the defined project area. Please read the introduction to each section that follows (Endangered Species, Migratory Birds, USFWS Facilities, and NWI Wetlands)for additional information applicable to the trust resources addressed in that section.

The primary information used to generate this list is the known or expected range of each species. Additional areas of influence (AOI)for species are also considered. An AOI includes areas outside of the species range if the species could be indirectly affected by activities in that area (e.g., placing a dam upstream of a fish population even if that fish does not occur at the dam site, may indirectly impact the species by reducing or eliminating water flow downstream). Because species can move, and site conditions can change, the species on this list are not guaranteed to be found on or near the project area. To fully determine any potential effects to species, additional site-specific and project-specific information is often required. Section 7 of the Endangered Species Act requires Federal agencies to "request of the Secretary information whether any species which is listed or proposed to be listed may be present in the area of such proposed action" for any project that is conducted, permitted, funded, or licensed by any Federal agency. A letter from the local office and a species list which fulfills this requirement can only be obtained by requesting an official species list from either the Regulatory Review section in IPaC (see directions below) or from the local field office directly. For project evaluations that require USFWS concurrence/review, please return to the IPaC website and request an official species list by doing the following: 1. Draw the project location and click CONTINUE. 2. Click DEFINE PROJECT. 3. Log in (if directed to do so). 4. Provide a name and description for your project. 5. Click REQUEST SPECIES LIST.

Probability of Presence Summary The graphs below provide our best understanding of when birds of concern are most likely to be present in your project area. This information can be used to tailor and schedule your project activities to avoid or minimize impacts to birds. Please make sure you read and understand the FAQ "Proper Interpretation and Use of Your Migratory Bird Report" before using or attempting to interpret this report. Probability of Presence ( ) Each green bar represents the bird's relative probability of presence in the 10km grid cell(s)your project overlaps during a particular week of the year. (A year is represented as 12 4-week months.) A taller bar indicates a higher probability of species presence. The survey effort (see below) can be used to establish a level of confidence in the presence score. One can have higher confidence in the presence score if the corresponding survey effort is also high. How is the probability of presence score calculated?The calculation is done in three steps: 1. The probability of presence for each week is calculated as the number of survey events in the week where the species was detected divided by the total number of survey events for that week. For example, if in week 12 there were 20 survey events and the Spotted Towhee was found in 5 of them, the probability of presence of the Spotted Towhee in week 12 is 0.25. 2. To properly present the pattern of presence across the year, the relative probability of presence is calculated. This is the probability of presence divided by the maximum probability of presence across all weeks. For example, imagine the probability of presence in week 20 for the Spotted Towhee is 0.05, and that the probability of presence at week 12 (0.25) is the maximum of any week of the year. The relative probability of presence on week 12 is 0.25/0.25 = 1; at week 20 it is 0.05/0.25 = 0.2. 3. The relative probability of presence calculated in the previous step undergoes a statistical conversion so that all possible values fall between 0 and 10, inclusive. This is the probability of presence score. To see a bar's probability of presence score, simply hover your mouse cursor over the bar. Breeding Season ( ) Yellow bars denote a very liberal estimate of the time-frame inside which the bird breeds across its entire range. If there are no yellow bars shown for a bird, it does not breed in your project area. Survey Effort (1) Vertical black lines superimposed on probability of presence bars indicate the number of surveys performed for that species in the 10km grid cell(s)your project area overlaps. The number of surveys is expressed as a range, for example, 33 to 64 surveys. To see a bar's survey effort range, simply hover your mouse cursor over the bar. No Data (—) A week is marked as having no data if there were no survey events for that week. https://ecos.fws.gov/ipac/location/MINQVMCUIFFE5EKXUFRWVBV7FI/resources 7/15 10/27/21,3:02 PM IPaC: Explore Location resources Survey Timeframe Surveys from only the last 10 years are used in order to ensure delivery of currently relevant information.

Tell me more about conservation measures I can implement to avoid or minimize impacts to migratory birds. Nationwide Conservation Measures describes measures that can help avoid and minimize impacts to all birds at any location year round. Implementation of these measures is particularly important when birds are most likely to occur in the project area.When birds may be breeding in the area, identifying the locations of any active nests and avoiding their destruction is a very helpful impact minimization measure.To see when birds are most likely to occur and be breeding in your project area,view the Probability of Presence Summary.Additional measures or permits may be advisable depending on the type of activity you are conducting and the type of infrastructure or bird species present on your project site. What does IPaC use to generate the migratory birds potentially occurring in my specified location? The Migratory Bird Resource List is comprised of USFWS Birds of Conservation Concern (BCC)and other species that may warrant special attention in your project location. The migratory bird list generated for your project is derived from data provided by the Avian Knowledge Network ,(AKN).The AKN data is based on a growing collection of survey., banding, and citizen science datasets and is queried and filtered to return a list of those birds reported as occurring in the 10km grid cell(s)which your project intersects, and that have been identified as warranting special attention because they are a BCC species in that area, an eagle(Eagle Act requirements may apply), or a species that has a particular vulnerability to offshore activities or development. Again, the Migratory Bird Resource list includes only a subset of birds that may occur in your project area. It is not representative of all birds that may occur in your project area.To get a list of all birds potentially present in your project area, please visit the AKN Phenology Tool. https://ecos.fws.gov/ipac/location/MINQVMCUIFFE5EKXUFRWVBV7FI/resources 11/15 10/27/21,3:02 PM IPaC: Explore Location resources What does IPaC use to generate the probability of presence graphs for the migratory birds potentially occurring in my specified location? The probability of presence graphs associated with your migratory bird list are based on data provided by the Avian Knowledge Network(AKN).This data is derived from a growing collection of survey., banding, and citizen science datasets . Probability of presence data is continuously being updated as new and better information becomes available.To learn more about how the probability of presence graphs are produced and how to interpret them,go the Probability of Presence Summary and then click on the "Tell me about these graphs" link. How do I know if a bird is breeding,wintering, migrating or present year-round in my project area? To see what part of a particular bird's range your project area falls within (i.e. breeding,wintering, migrating or year-round),you may refer to the following resources:The Cornell Lab of Ornithology All About Birds Bird Guide, or (if you are unsuccessful in locating the bird of interest there),the Cornell Lab of Ornithology Neotropical Birds guide. If a bird on your migratory bird species list has a breeding season associated with it, if that bird does occur in your project area,there may be nests present at some point within the timeframe specified. If"Breeds elsewhere" is indicated,then the bird likely does not breed in your project area. What are the levels of concern for migratory birds? Migratory birds delivered through IPaC fall into the following distinct categories of concern: 1. "BCC Rangewide" birds are Birds of Conservation Concern (BCC)that are of concern throughout their range anywhere within the USA(including Hawaii,the Pacific Islands, Puerto Rico, and the Virgin Islands); 2. "BCC- BCR" birds are BCCs that are of concern only in particular Bird Conservation Regions(BCRs) in the continental USA; and 3. "Non-BCC-Vulnerable" birds are not BCC species in your project area, but appear on your list either because of the Eagle Act requirements(for eagles)or(for non-eagles) potential susceptibilities in offshore areas from certain types of development or activities(e.g. offshore energy development or longline fishing). Although it is important to try to avoid and minimize impacts to all birds, efforts should be made, in particular,to avoid and minimize impacts to the birds on this list, especially eagles and BCC species of rangewide concern. For more information on conservation measures you can implement to help avoid and minimize migratory bird impacts and requirements for eagles, please see the FAQs for these topics. Details about birds that are potentially affected by offshore projects For additional details about the relative occurrence and abundance of both individual bird species and groups of bird species within your project area off the Atlantic Coast, please visit the Northeast Ocean Data Portal.The Portal also offers data and information about other taxa besides birds that may be helpful to you in your project review. Alternately,you may download the bird model results files underlying the portal maps through the NOAA NCCOS Integrative Statistical Modeling and Predictive Mapping of Marine Bird Distributions and Abundance on the Atlantic Outer Continental Shelf project webpage. Bird tracking data can also provide additional details about occurrence and habitat use throughout the year, including migration. Models relying on survey data may not include this information. For additional information on marine bird tracking data, see the Diving Bird Study and the nanotag studies or contact Caleb Spiegel or Pam Loring. What if I have eagles on my list? If your project has the potential to disturb or kill eagles,you may need to obtain a permit to avoid violating the Eagle Act should such impacts occur. https://ecos.fws.gov/ipac/location/MINQVMCUIFFE5EKXUFRWVBV7FI/resources 12/15 10/27/21,3:02 PM IPaC: Explore Location resources Proper Interpretation and Use of Your Migratory Bird Report The migratory bird list generated is not a list of all birds in your project area, only a subset of birds of priority concern.To learn more about how your list is generated, and see options for identifying what other birds may be in your project area, please see the FAQ "What does IPaC use to generate the migratory birds potentially occurring in my specified location". Please be aware this report provides the "probability of presence" of birds within the 10 km grid cell(s)that overlap your project; not your exact project footprint. On the graphs provided, please also look carefully at the survey effort(indicated by the black vertical bar)and for the existence of the "no data" indicator(a red horizontal bar).A high survey effort is the key component. If the survey effort is high,then the probability of presence score can be viewed as more dependable. In contrast, a low survey effort bar or no data bar means a lack of data and,therefore, a lack of certainty about presence of the species.This list is not perfect; it is simply a starting point for identifying what birds of concern have the potential to be in your project area, when they might be there, and if they might be breeding(which means nests might be present).The list helps you know what to look for to confirm presence, and helps guide you in knowing when to implement conservation measures to avoid or minimize potential impacts from your project activities, should presence be confirmed.To learn more about conservation measures,visit the FAQ "Tell me about conservation measures I can implement to avoid or minimize impacts to migratory birds" at the bottom of your migratory bird trust resources page.

The accuracy of image interpretation depends on the quality of the imagery, the experience of the image analysts, the amount and quality of the collateral data and the amount of ground truth verification work conducted. Metadata should be consulted to determine the date of the source imagery used and any mapping problems. Wetlands or other mapped features may have changed since the date of the imagery or field work.There may be occasional differences in polygon boundaries or classifications between the information depicted on the map and the actual conditions on site. Data exclusions Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands.These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and nearshore coastal waters. Some deepwater reef communities(coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their depth, go undetected by aerial imagery. https://ecos.fws.gov/ipac/location/MINQVMCUIFFE5EKXUFRWVBV7FI/resources 14/15 10/27/21,3:02 PM IPaC: Explore Location resources Data precautions Federal, state, and local regulatory agencies with jurisdiction over wetlands may define and describe wetlands in a different manner than that used in this inventory.There is no attempt, in either the design or products of this inventory,to define the limits of proprietary jurisdiction of any Federal, state, or local government or to establish the geographical scope of the regulatory programs of government agencies.

Expand All I Collapse All Introduction Introduction The Montana Natural Heritage Program(MTNHP)serves as the state's information source for animals,plants,and plant communities with a focus on species and communities that are rare,threatened, and as a result are at risk or potentially at risk of extirpation in Montana. This report on Montana Animal Species of Concern is produced jointly by the Montana Natural Heritage Program(MTNHP)and Montana Department of Fish,Wildlife,and Parks(MFWP). Montana Al native Montana animals that are considered to be"at risk"due to declining population trends,threats to their habitats,and/or restricted distribution. Also included in this report are Potential Animal Species of Concern--animals for which current,often limited,information suggests potential vulnerability or for which additional data are needed befor assessment can be made. We also include Special Status Species which are species that have some legal protections in place,but are otherwise not Montana Species of Concern. Bald Eagle is a Special Status Species becau: protected under the Endangered Species Act and is also no longer a Montana Species of Concern,it is still protected under the Bald and Golden Eagle Protection Act of 1940(16 U.S.C.668-668c). I Species of Concern,having a state rank of SNA because of a lack of information on its migratory stopover use of Montana's wetlands. However it is a Special Status Species because it is listed as Thre Endangered Species Act(16 U.S.C.1531-1544). Over the last 200 years,5 species with historic breeding ranges in Montana have been extirpated from the state;Woodland Caribou(Rangifer tarandus),Greater Prairie-Chicken(Tympanuchus cupido), (Ectopistes migratodus),Pilose Crayfish(Pacifastacus gambelii),and Rocky Mountain Locust(Melanoplus spretus). Designation as a Montana Animal Species of Concern or Potential Animal Species o' regulatory classification. Instead,these designations provide a basis for resource managers and decision-makers to make proactive decisions regarding species conservation and data collection prioritie extirpations. Status determinations are made by MTNHP and MFWP biologists in consultation with representatives of the Montana Chapter of the Wildlife Society,the Montana Chapter of the American Fisheries Soo process for evaluating and assigning status designations uses the Natural Heritage Program ranking system,described below,which forms the basis for identifying Montana Species of Concern. How to Read the Lists What Species are Included in this Report Montana Species of Concern are defined as vertebrate animals with a state rank of S1,S2,or S3. Vertebrate species with a rank indicating uncertainty(SU),a"range rank"extending below the S3 cutol ranked S4 for which there is limited baseline information on status are considered Potential Species of Concern. Because documentation for invertebrates is typically less complete than for vertebrates, are included as SOC. Invertebrates with a range rank extending below S2(e.g.,S2S3)are included as SOC only if their global ranks are G2G3 or G3,or if experts agree their occurrence in Montana ha: documented. Other invertebrates of concern with global ranks other than G1,G2,or G3 and with state ranks below S2 or range ranks extending below S2(e.g.,S3S4)are treated as Potential Species c Organization of List Both-the list of Species of Concern and the list of Potential Species of Concern are grouped taxonomically in the following order:mammals,birds,reptiles,amphibians,fish,and various invertebrates. W you can sort species by common name or scientific name. County Distribution This column lists the documented county distribution for each species,including extant and historical occurrences.Any occurrences that cross county boundaries are counted for each county.Many olde specimen collections are only known from vague location information and the area mapped as the potential area of observation may be quite large,leading to more than one county being counted. Additions and Deletions Species that have been added to or deleted from the SOC list due to changes in their state rank are reported in separate sections below;changes in global ranks are not tracked in this report. https://mtnhp.org/SpeciesOfConcern/?AorP=a 1/21 11/3/21, 11:42 AM MTNHRorg-SOC Report Montana Species Ranking Codes (GRank, SRank) Montana employs a standardized ranking system to denote global(range-wide)and state status(NatureServe 2006). Species are assigned numeric ranks ranging from 1(highest risk,greatest concerr reflecting the relative degree of risk to the species'viability,based upon available information. A number of factors are considered in assigning ranks—the number,size and quality of known occurrences or populations,distribution,trends(if known),intrinsic vulnerability,habitat specificity,and de' of assigning state ranks for each taxon relies heavily on the number of occurrences and Species Occurrence(OE)ranks,which is a ranking system of the quality(usually A through D)of each known ocr such as size(#of individuals)and habitat quality. The remaining factors noted above are also incorporated into the ranking process when they are known. The"State Rank Reason"field in the Montam additional information on the reasons for a particular species'rank. Rank Definition G1 S1 At high risk because of extremely limited and/or rapidly declining population numbers,range and/or habitat,making it highly vulnerable to global extinction or extirpation in the state. G2 S2 At risk because of very limited and/or potentially declining population numbers,range and/or habitat,making it vulnerable to global extinction or extirpation in the state. G3 S3 Potentially at risk because of limited and/or declining numbers,range and/or habitat,even though it may be abundant in some areas. G4 S4 Apparently secure,though it may be quite rare in parts of its range,and/or suspected to be declining. G5 SS Common,widespread,and abundant(although it may be rare in parts of its range).Not vulnerable in most of its range. GX SX Presumed Extinct or Extirpated-Species is believed to be extinct throughout its range or extirpated in Montana. Not located despite intensive searches of historical sites and other appropria likelihood that it will ever be rediscovered. GH SH Historical,known only from records usually 40 or more years old;may be rediscovered. GNR SNR Not Ranked as of yet. GU SU Unrankable-Species currently unrankable due to lack of information or due to substantially conflicting information about status or trends. GNA SNA A conservation status rank is not applicable because the species or ecosystem is not a suitable target for conservation activities as a result of being: 1)not confidently present in the state; 2 3)a long distance migrant with accidental or irregular stopovers;or 4)a hybrid without conservation value. Combination or Range Ranks G#G# Indicates a range of uncertainty about the status of the species(e.g.,G1G3=Global Rank ranges between G1 and G3). or S#S# S#,S# Indicates that populations in different geographic portions of the species'range in Montana have a different conservation status(e.g.,S1 west of the Continental Divide and S4 east of the Contin Sub-rank T# Rank of a subspecies or variety.Appended to the global rank of the full species,e.g.G4T3 Qualifiers Q Questionable taxonomy that may reduce conservation priority-Distinctiveness of this entity as a taxon at the current level is questionable;resolution of this uncertainty may result in change from e hybrid,or inclusion of this taxon in another taxon,with the resulting taxon having a lower-priority(numerically higher)conservation status rank. Appended to the global rank,e.g.G3Q ? Inexact Numeric Rank-Denotes uncertainty;inexactness. HYB Hybrid-Entity not ranked because it represents an interspeciflc hybrid and not a species. C Captive or Cultivated Only-Species at present exists only in captivity or cultivation,or as a reintroduced population not yet established. A Accidental-Species is accidental or casual in Montana,in other words,infrequent and outside usual range. Includes species(usually birds or butterflies)recorded once or only a few times at a h species may have bred on the few occasions they were recorded. SYN Synonym-Species reported as occurring in Montana,but the Montana Natural Heritage Program does not recognize the taxon;therefore the species is not assigned a rank. B Breeding-Rank refers to the breeding population of the species in Montana. Appended to the state rank,e.g.S2B,S5N=At risk during breeding season,but common in the winter N Nonbreeding-Rank refers to the non-breeding population of the species in Montana. Appended to the state rank,e.g.S58,S2N=Common during breeding season,but at risk in the winter M Migratory-Species occurs in Montana only during migration. https://mtnhp.org/SpeciesOfConcern/?AorP=a 2/21 11/3/21, 11:42 AM MTNHRorg-SOC Report Federal Status Designations in this column reflect the status of a species under the U.S.Endangered Species Act(ESA),or as"sensitive"by the U.S.Forest Service(USFS)or Bureau of Land Management(BLM). U.S. Fish and Wildlife Service (Endangered Species Act) Status of a taxon under the federal Endangered Species Act of 197 (16 U.S.C.A.§1531-1543(Supp.1996)) Designation Descriptions LE Listed endangered:Any species in danger of extinction throughout all or a significant portion of its range(16 U.S.C.1532(6)). LT Listed threatened:Any species likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range(16 U.S.C.1532(20)). C Candidate:Those taxa for which sufficient information on biological status and threats exists to propose to list them as threatened or endangered. We encourage their consideration in environ partnerships;however,none of the substantive or procedural provisions of the Act apply to candidate species. P Proposed threatened:Any species that is proposed in the Federal Register to be listed under section 4 of the Act. DM Recovered,delisted,and being monitored-Any previously listed species that is now recovered,has been delisted,and is being monitored. NL Not listed-No designation. XE Experimental-Essential population-An experimental population whose loss would be likely to appreciably reduce the likelihood of the survival of the species in the wild. XN Experimental-Nonessential population-An experimental population of a listed species reintroduced into a specific area that receives more flexible management under the Act. CH Critical Habitat-The specific areas(i)within the geographic area occupied by a species,at the time it is listed,on which are found those physical or biological features(1)essential to conservf may require special management considerations or protection;and(ii)specific areas outside the geographic area occupied by the species at the time it is listed upon determination that such ar conserve the species. PS Partial status-status in only a portion of the species'range. Typically indicated in a"full"species record where an infraspecific taxon or population,that has a record in the database has USE species does not. For example,Yellow-billed Cuckoo(Coccyzus americans)is ranked PS:LT. Partial Status-Listed Threatened. Designated as Threatened in the Western U.S.Distinct Pop (subspecies occidentalis) BGEPA The Bald and Golden Eagle Protection Act of 1940(BGEPA)-(16 U.S.C.668-668c)prohibits anyone,without a permit issued by the Secretary of the Interior,from taking bald or golden eag nests,or eggs. The BGEPA provides criminal and civil penalties for persons who take,possess,sell,purchase,barter,offer to sell,purchase or barter,transport,export or import,at any time of ...[or any golden eagle],alive or dead,or any part,nest,or egg thereof. The BGEPA defines take as pursue,shoot,shoot at,poison,wound,kill,capture,trap,collect,molest or disturb. "Distu bother a bald or golden eagle to a degree that causes,or is likely to cause,based on the best scientific information available,1)injury to an eagle,2)a decrease in its productivity,by substantie breeding,feeding,or sheltering behavior,or 3)nest abandonment,by substantially interfering with normal breeding,feeding,or sheltering behavior.

MBTA The Migratory Bird Treaty Act(MBTA)-(16 U.S.C.§§703-712,July 3,1918,as amended 1936,1960,1968,1969,1974,1978,1986 and 1989)implements four treaties that provide for inter migratory birds. The statute's language is clear that actions resulting in a"taking"or possession(permanent or temporary)of a protected species,in the absence of a U.S.Fish and Wildlife Sei regulatory authorization,are a violation of the MBTA. The MBTA states,"Unless and except as permitted by regulations...it shall be unlawful at any time,by any means,or in any manner to pr ...possess,offer for sale,sell...purchase...ship,export,import...transport or cause to be transported...any migratory bird,any part,nest,or eggs of any such bird....[The Act]prohibits the 1 transportation,import and export of migratory birds,their eggs,parts,and nests,except when specifically authorized by the Department of the Interior." The word"take"is defined by regulation wound,kill,trap,capture,or collect,or attempt to pursue,hunt,shoot,wound,kill,trap,capture,or collect." The USFWS maintains a list of species protected by the MBTA at 50 CFR 10.13. thousand species of migratory birds,including eagles and other raptors,waterfowl,shorebirds,seabirds,wading birds,and passerines. The USFWS also maintains a list of species not prote does not protect species that are not native to the United States or species groups not explicitly covered under the MBTA;these include species such as the house(English)sparrow,European Eurasian collared-dove,and non-migratory upland game birds. BCC The 1988 amendment to the Fish and Wildlife Conservation Act mandates the U.S.Fish and Wildlife Service to identify species,subspecies,and populations of all migratory nongame birds the conservation actions,are likely to become candidates for listing under the Endangered Species Act. Birds of Conservation Concern 2008(BCC 2008)is the most recent effort to carry out thi of this report is to accurately identify the migratory and non-migratory bird species(beyond those already designated as federally threatened or endangered)that represent the Service's highes BCC10,BCC11,and BCC17 designations represent inclusion on the Birds of Conservation Concern list for Bird Conservation Region 10,11,and 17 in Montana,respectively. Bureau of Land Management (BLM) BLM Sensitive Species are defined by a BLM 6840 Manual as native species found on BLM-administered lands for which the BLM has the capability to significantly affect the conservation status of the management,and either:(1)there is information that a species has recently undergone,is undergoing,or is predicted to undergo a downward trend such that the viability of the species or a distinct popu is at risk across all or a significant portion of the species range,or;(2)the species depends on ecological refugia or specialized or unique habitats on BLM-administered lands,and there is evidence that with alteration such that the continued viability of the species in that area would be at risk. Designation Descriptions Endangered Denotes species that are listed as Endangered under the Endangered Species Act Threatened Denotes species that are listed as Threatened under the Endangered Species Act Sensitive Denotes species listed as Sensitive on BLM lands U.S. Forest Service (USFS) Designation Descriptions Endangered Listed as Endangered(LE)under the U.S.Endangered Species Act. Threatened Listed as Threatened(LT)under the U.S.Endangered Species Act. Proposed Any species that is proposed in the Federal Register to be listed under section 4 of the Act. Candidate Those taxa for which sufficient information on biological status and threats exists to propose to list them as threatened or endangered. We encourage their consideration in environment< however,none of the substantive or procedural provisions of the Act apply to candidate species. Sensitive U.S.Forest Service Manual(2670.22)defines Sensitive Species on Forest Service lands as those for which population viability is a concern as evidenced by a significant downward trem significant downward trend in habitat capacity. These designations were last updated in 2011 and they apply only on USFS-administered lands with land management plans finalized prit Species designations are being replaced by Species of Conservation Concern designations on individual National Forest as revised land management plans are finalized under the 2012 Species of A species,other than federally recognized Threatened,Endangered,Proposed,or Candidate species,that is known to occur in the plan area and for which the regional forester has date Conservation available scientific information indicates substantial concern about the species'capability to persist over the long-term in the plan area(36 CFR 219.9).

Expand All I Collapse All Introduction Introduction The Montana Natural Heritage Program(MTNHP)serves as the state's information source for Species of Concern(SOC)--plants and animals that are rare,threatened,and/or have declining population potentially at risk of extirpation in Montana. This report is based on information gathered from field inventories,publications,reports,herbaria specimens,and the knowledge of botanists and other taxon SOC category generally include all vascular plant taxa ranked S1,S2,S3 or SH. Nonvascular taxa(bryophytes and lichens)which are not as well documented or studied as vascular plant taxa in the sta similar criteria as vascular taxa but are more strictly limited to those taxa which are believed to be the rarest or most vulnerable to extirpation based on current information. Designation as a Species of Concern is not a statutory or regulatory classification. Instead,these designations provide a basis for resource managers and decision-makers to make proactive decisions r conservation and data collection priorities in order to maintain viable populations and avoid extirpation of species from the state. MTNHP may designate additional taxa as Potential Species of Concern( designation include species or subspecies which may be rare,have a restricted range in the state or are otherwise vulnerable to extirpation in at least part of their range but otherwise do not meet the cri An additional designation of Status Under Review is used for those taxa for which additional information is needed to accurately assign a status rank or far which conflicting information exists. Taxa desk Review are not included in this document but can be found in the on-line Fielciguide(fieldguide.mt.gov). This web-based report,which replaces the 2006 Plant Species of Concern publication,identifies vascular plant Species of Concern(SOC),bryophyte SOC and lichen SOC in Montana. The MTNHP con updates status ranks as new information and data become available through field surveys,research,and submitted observations. Status ranks and information supporting them are reviewed by botanist you wish to comment or contribute information to this process please contact the MTNHP Botanist. The information we receive from botanists and others throughout the state is essential in this process, accurate assessments of species'status. We continue to ask that all observations for SOC,PSOC and Review Status plants be reported to the Heritage Program. A copy of the field survey form specify should be submitted is available on our website(mtnhp.org). Information concerning plant species contained on the SOC,PSOC or Review lists may be viewed on the MTNHP's on-line Montana Plant Field Guide. The Field Guide provides information for vascular including species'characteristics,identification,habitat,distribution,state rank reasons and references,as well as technical illustrations and photographs of the plants and their habitats. For each specie website(natureserve.org)provides access to information on the status of the species throughout North America,assembled from state and provincial Natural Heritage databases. Information in the M( continuously updated and expanded,so please check it often for current species'information. If you have questions concerning the field guide or find errors or omissions please contact the MTNHP. Status lists of SOC plants may be queried on-line by county and/or township;taxonomic group or one of several rank/statuS criteria. More detailed information or additional assistance can be requested Information Request function on our website,or by phone,e-mail or mail. How to Read the Lists The SOC list is organized alphabetically by scientific name(Genus and specific epithet followed by subspecific epithet if any)within the major groups of Vascular Plants,Bryophytes(Mosses and Liverwc plants are further sorted by the subgroups:Ferns and Fern Allies,Gymnosperms(if any),Flowering Plants-Dicots and Flowering Plants-Monocots. The list can also be sorted alphabetically by the comrr scientific names as well as the Family name are included in adjacent columns for each species. The nomenclature and taxonomy for many groups of plants continues to change as new research is cond a result no one nomenclatural reference is followed. Publications and web resources which are most relevant to Montana plants include Vascular Plants of Montana(Dorn 1984),NatureServe Explorer,. database,Flora of North America(1993-),Grasses of Montana(Lavin and Seibert 2011)and Flora of the Pacific Northwest(Hitchcock and Cronquist 1973). Additionally,an abundance of scientific litera plants is available and indispensable in the process of determining the nomenclature and taxonomic concepts used in this report. Species that have been added to or deleted from the SOC list due to changes in their global or state rank are reported in separate sections below. These changes are also reflected in the date displayec shows when an addition or deletion to the list last occurred. County Distribution Montana counties of record are listed alphabetically with each species. County records of occurrence are determined directly from mapped species occurrences(SO's)in MTNHP databases. A record c county may be based on a historical observation which may no longer be extant. Additionally,some plant observations with vague locality information are not mapped in MTNHP databases and as resull county distribution for that particular species. https://mtnhp.org/SpeciesOfConcern/?AorP=p 1/18 11/3/21, 11:44 AM MTNHRorg-SOC Report Montana Species Ranking Codes (GRank, SRank) Montana employs a standardized ranking system to denote global(range-wide)and state status(NatureServe 2006). Species are assigned numeric ranks ranging from 1(highest risk,greatest concerr reflecting the relative degree of risk to the species'viability,based upon available information. A number of factors are considered in assigning ranks—the number,size and quality of known occurrences or populations,distribution,trends(if known),intrinsic vulnerability,habitat specificity,and de' of assigning state ranks for each taxon relies heavily on the number of occurrences and Species Occurrence(OE)ranks,which is a ranking system of the quality(usually A through D)of each known occ such as size(#of individuals)and habitat quality. The remaining factors noted above are also incorporated into the ranking process when they are known. The"State Rank Reason"field in the Montan; additional information on the reasons for a particular species'rank. Rank Definition G1 S1 At high risk because of extremely limited and/or rapidly declining population numbers,range and/or habitat,making it highly vulnerable to global extinction or extirpation in the state. G2 S2 At risk because of very limited and/or potentially declining population numbers,range and/or habitat,making it vulnerable to global extinction or extirpation in the state. G3 S3 Potentially at risk because of limited and/or declining numbers,range and/or habitat,even though it may be abundant in some areas. G4 S4 Apparently secure,though it may be quite rare in parts of its range,and/or suspected to be declining. G5 SS Common,widespread,and abundant(although it may be rare in parts of its range).Not vulnerable in most of its range. GX SX Presumed Extinct or Extirpated-Species is believed to be extinct throughout its range or extirpated in Montana. Not located despite intensive searches of historical sites and other appropria likelihood that it will ever be rediscovered. GH SH Historical,known only from records usually 40 or more years old;may be rediscovered. GNR SNR Not Ranked as of yet. GU SU Unrankable-Species currently unrankable due to lack of information or due to substantially conflicting information about status or trends. GNA SNA A conservation status rank is not applicable because the species or ecosystem is not a suitable target for conservation activities as a result of being: 1)not confidently present in the state; 2 3)a long distance migrant with accidental or irregular stopovers;or 4)a hybrid without conservation value. Combination or Range Ranks G#G# Indicates a range of uncertainty about the status of the species(e.g.,GI G3=Global Rank ranges between G1 and G3). or S#S# S#,S# Indicates that populations in different geographic portions of the species'range in Montana have a different conservation status(e.g.,S1 west of the Continental Divide and S4 east of the Conlin Sub-rank T# Rank of a subspecies or variety.Appended to the global rank of the full species,e.g.G4T3 Qualifiers Q Questionable taxonomy that may reduce conservation priority-Distinctiveness of this entity as a taxon at the current level is questionable;resolution of this uncertainty may result in change from e hybrid,or inclusion of this taxon in another taxon,with the resulting taxon having a lower-priority(numerically higher)conservation status rank. Appended to the global rank,e.g.G3Q ? Inexact Numeric Rank-Denotes uncertainty;inexactness. HYB Hybrid-Entity not ranked because it represents an interspecific hybrid and not a species. C Captive or Cultivated Only-Species at present exists only in captivity or cultivation,or as a reintroduced population not yet established. A Accidental-Species is accidental or casual in Montana,in other words,infrequent and outside usual range. Includes species(usually birds or butterflies)recorded once or only a few times at a h species may have bred on the few occasions they were recorded. SYN Synonym-Species reported as occurring in Montana,but the Montana Natural Heritage Program does not recognize the taxon;therefore the species is not assigned a rank. B Breeding-Rank refers to the breeding population of the species in Montana. Appended to the state rank,e.g.S2B,S5N=At risk during breeding season,but common in the winter N Nonbreeding-Rank refers to the non-breeding population of the species in Montana. Appended to the state rank,e.g.S5B S2N=Common during breeding season,but at risk in the winter M Migratory-Species occurs in Montana only during migration. https://mtnhp.org/SpeciesOfConcern/?AorP=p 2/18 11/3/21, 11:44 AM MTNHRorg-SOC Report Federal Status Designations in this column reflect the status of a species under the U.S.Endangered Species Act(ESA),or as"sensitive"by the U.S.Forest Service(USFS)or Bureau of Land Management(BLM). U.S. Fish and Wildlife Service (Endangered Species Act) Status of a taxon under the federal Endangered Species Act of 197 (16 U.S.C.A.§1531-1543(Supp.1996)) Designation Descriptions LE Listed endangered:Any species in danger of extinction throughout all or a significant portion of its range(16 U.S.C.1532(6)). LT Listed threatened:Any species likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range(16 U.S.C.1532(20)). C Candidate:Those taxa for which sufficient information on biological status and threats exists to propose to list them as threatened or endangered. We encourage their consideration in environ partnerships;however,none of the substantive or procedural provisions of the Act apply to candidate species. P Proposed threatened:Any species that is proposed in the Federal Register to be listed under section 4 of the Act. DM Recovered,delisted,and being monitored-Any previously listed species that is now recovered,has been delisted,and is being monitored. NL Not listed-No designation. XE Experimental-Essential population-An experimental population whose loss would be likely to appreciably reduce the likelihood of the survival of the species in the wild. XN Experimental-Nonessential population-An experimental population of a listed species reintroduced into a specific area that receives more flexible management under the Act. CH Critical Habitat-The specific areas(i)within the geographic area occupied by a species,at the time it is listed,on which are found those physical or biological features(1)essential to conservf may require special management considerations or protection;and(ii)specific areas outside the geographic area occupied by the species at the time it is listed upon determination that such ar conserve the species. PS Partial status-status in only a portion of the species'range. Typically indicated in a"full"species record where an infraspecific taxon or population,that has a record in the database has USE species does not. For example,Yellow-billed Cuckoo(Coccyzus americans)is ranked PS:LT. Partial Status-Listed Threatened. Designated as Threatened in the Western U.S.Distinct Pop (subspecies occidentalis) BGEPA The Bald and Golden Eagle Protection Act of 1940(BGEPA)-(16 U.S.C.668-668c)prohibits anyone,without a permit issued by the Secretary of the Interior,from taking bald or golden eag nests,or eggs. The BGEPA provides criminal and civil penalties for persons who take,possess,sell,purchase,barter,offer to sell,purchase or barter,transport,export or import,at any time of ...[or any golden eagle],alive or dead,or any part,nest,or egg thereof.

MBTA The Migratory Bird Treaty Act(MBTA)-(16 U.S.C.§§703-712,July 3,1918,as amended 1936,1960,1968,1969,1974,1978,1986 and 1989)implements four treaties that provide for inter migratory birds. The statute's language is clear that actions resulting in a"taking"or possession(permanent or temporary)of a protected species,in the absence of a U.S.Fish and Wildlife Sei regulatory authorization,are a violation of the MBTA. The MBTA states,"Unless and except as permitted by regulations...it shall be unlawful at any time,by any means,or in any manner to pr ...possess,offer for sale,sell...purchase...ship,export,import...transport or cause to be transported...any migratory bird,any part,nest,or eggs of any such bird....[The Act]prohibits the 1 transportation,import and export of migratory birds,their eggs,parts,and nests,except when specifically authorized by the Department of the Interior." The word"take"is defined by regulation wound,kill,trap,capture,or collect,or attempt to pursue,hunt,shoot,wound,kill,trap,capture,or collect." The USFWS maintains a list of species protected by the MBTA at 50 CFR 10.13. thousand species of migratory birds,including eagles and other raptors,waterfowl,shorebirds,seabirds,wading birds,and passerines. The USFWS also maintains a list of species not prote does not protect species that are not native to the United States or species groups not explicitly covered under the MBTA;these include species such as the house(English)sparrow,European Eurasian collared-dove,and non-migratory upland game birds. BCC The 1988 amendment to the Fish and Wildlife Conservation Act mandates the U.S.Fish and Wildlife Service to identify species,subspecies,and populations of all migratory nongame birds the conservation actions,are likely to become candidates for listing under the Endangered Species Act. Birds of Conservation Concern 2008(BCC 2008)is the most recent effort to carry out thi of this report is to accurately identify the migratory and non-migratory bird species(beyond those already designated as federally threatened or endangered)that represent the Service's highes BCC10,BCC11,and BCC17 designations represent inclusion on the Birds of Conservation Concern list for Bird Conservation Region 10,11,and 17 in Montana,respectively. Bureau of Land Management (BLM) BLM Sensitive Species are defined by a BLM 6840 Manual as native species found on BLM-administered lands for which the BLM has the capability to significantly affect the conservation status of the management,and either:(1)there is information that a species has recently undergone,is undergoing,or is predicted to undergo a downward trend such that the viability of the species or a distinct popu is at risk across all or a significant portion of the species range,or;(2)the species depends on ecological refugia or specialized or unique habitats on BLM-administered lands,and there is evidence that with alteration such that the continued viability of the species in that area would be at risk. Designation Descriptions Endangered Denotes species that are listed as Endangered under the Endangered Species Act Threatened Denotes species that are listed as Threatened under the Endangered Species Act Sensitive Denotes species listed as Sensitive on BLM lands U.S. Forest Service (USFS) Designation Descriptions Endangered Listed as Endangered(LE)under the U.S.Endangered Species Act. Threatened Listed as Threatened(LT)under the U.S.Endangered Species Act. Proposed Any species that is proposed in the Federal Register to be listed under section 4 of the Act. Candidate Those taxa for which sufficient information on biological status and threats exists to propose to list them as threatened or endangered. We encourage their consideration in environment< however,none of the substantive or procedural provisions of the Act apply to candidate species. Sensitive U.S.Forest Service Manual(2670.22)defines Sensitive Species on Forest Service lands as those for which population viability is a concern as evidenced by a significant downward trem significant downward trend in habitat capacity. These designations were last updated in 2011 and they apply only on USFS-administered lands with land management plans finalized prit Species designations are being replaced by Species of Conservation Concern designations on individual National Forest as revised land management plans are finalized under the 2012 Species of A species,other than federally recognized Threatened,Endangered,Proposed,or Candidate species,that is known to occur in the plan area and for which the regional forester has date Conservation available scientific information indicates substantial concern about the species'capability to persist over the long-term in the plan area(36 CFR 219.9).

Assessment of the impact of contaminant migration generally has two principle investigative components: 1. Groundwater flow direction, and 2. Groundwater flow velocity. Groundwater flow direction may be impacted by surface topography, hydrology, hydrogeology, characteristics of the soil, and nearby wells. Groundwater flow velocity is generally impacted by the nature of the geologic strata. TC6711564.2s Page A-1 GEOCHECe - PHYSICAL SETTING SOURCE SUMMARY GROUNDWATER FLOW DIRECTION INFORMATION Groundwater flow direction for a particular site is best determined by a qualified environmental professional using site-specific well data. If such data is not reasonably ascertainable, it may be necessary to rely on other sources of information, such as surface topographic information, hydrologic information, hydrogeologic data collected on nearby properties, and regional groundwater flow information (from deep aquifers). TOPOGRAPHIC INFORMATION Surface topography may be indicative of the direction of surficial groundwater flow. This information can be used to assist the environmental professional in forming an opinion about the impact of nearby contaminated properties or, should contamination exist on the target property,what downgradient sites might be impacted.

Such hydrogeologic information can be used to assist the environmental professional in forming an opinion about the impact of nearby contaminated properties or, should contamination exist on the target property,what downgradient sites might be impacted. AQUIFLOWO Search Radius: 1.000 Mile. EDR has developed the AQUIFLOW Information System to provide data on the general direction of groundwater flow at specific points. EDR has reviewed reports submitted by environmental professionals to regulatory authorities at select sites and has extracted the date of the report, groundwater flow direction as determined hydrogeologically, and the depth to water table. LOCATION GENERAL DIRECTION MAP ID FROM TP GROUNDWATER FLOW Not Reported TC6711564.2s Page A-3 GEOCHECe - PHYSICAL SETTING SOURCE SUMMARY GROUNDWATER FLOW VELOCITY INFORMATION Groundwater flow velocity information for a particular site is best determined by a qualified environmental professional using site specific geologic and soil strata data. If such data are not reasonably ascertainable, it may be necessary to rely on other sources of information, including geologic age identification, rock stratigraphic unit and soil characteristics data collected on nearby properties and regional soil information. In general, contaminant plumes move more quickly through sandy-gravelly types of soils than silty-clayey types of soils. GEOLOGIC INFORMATION IN GENERAL AREA OF TARGET PROPERTY Geologic information can be used by the environmental professional in forming an opinion about the relative speed at which contaminant migration may be occurring.

Asbestos is a naturally occurring mineral, three varieties of which (chrysotile, amosite, crocidolite) have been commonly used as fireproofing or binding agents in construction materials. Exposure to asbestos, as well as ACM, has been documented to cause lung diseases including asbestosis(scarring of the lung),lung cancer and mesothelioma(a cancer of the lung lining). Regulatory agencies have generally defined ACM as a material containing greater that one(1)percent asbestos, however some states(e.g. California) define ACM as materials having 0.1% asbestos. In order to define a homogenous material as non-ACM, a minimum number of samples must be collected from the material dependent upon its type and quantity. Homogenous materials defined as non-ACM must either have 1) no asbestos identified in all of its samples or 2) an identified asbestos concentration below the appropriate regulatory threshold. Asbestos concentrations are generally determined using polarized light microscopy or transmission electron microscopy. Point counting is an ACM analytical method to statistically quantify the percentage of asbestos in a sample.The asbestos component of ACM may either be friable or non-friable. Friable materials,when dry,can be crumbled,pulverized,or reduced to powder by hand pressure and have a higher potential for a fiber release than non-friable ACM. Non-friable ACM are materials that are firmly bound in a matrix by plastic, cement, etc. and, if handled carefully,will not become friable. Federal and state regulations require that either all suspect building materials be presumed ACM or that an asbestos survey be performed prior to renovation, dismantling, demolition, or other activities that may disturb potential ACM. Notifications are required prior to demolition and/or renovation activities that may impact the condition of ACM in a building.ACM removal may be required if the ACM is likely to be disturbed or damaged during the demolition or renovation. Abatement of friable or potentially friable ACM must be performed by a licensed abatement contractor in accordance with state rules and NESHAP. Additionally, OSHA regulations for work classification, worker training and worker protection will apply. AHERA Asbestos Hazard Emergency Response Act Aboveground Storage Tanks.ASTs are generally described as storage tanks less than 10%of which are below ground (i.e., buried).Tanks AST located in a basement, but not buried,are also considered ASTs.Whether, and the extent to which, an AST is regulated, is determined on a case-by-case basis and depends upon tank size,its contents and the jurisdiction of its location. BGS Below Ground Surface Brownfields State and/or tribal listing of Brownfield properties addressed by Cooperative Agreement Recipients or Targeted Brownfields Assessments. BTEX Benzene,Toluene, Ethylbenzene,and Xylenes.BTEX are VOC components found in gasoline and commonly used as analytical indicators of a petroleum hydrocarbon release. Comprehensive Environmental Response, Compensation and Liability Act (a.k.a. Superfund). CERCLA is the federal act that regulates CERCLA abandoned or uncontrolled hazardous waste sites. Under this Act,joint and several liability may be imposed on potentially responsible parties for cleanup-related costs.

INTRODCTION The Baxter Apartments are located on 20.11 acres located south of Baxter Lane, west of North 191h Avenue and north of Tschache Lane, along the future N 271h Ave. The legal description of the site is Tract 1 of COS No 1256 located in the NE '/4 of Section 2 T2S, R5E, P.M.M. in Gallatin County, Montana. The proposed development at the Baxter Apartments is comprised of infrastructure improvements including: roads, water system, sewer system and storm water facilities to serve the proposed 2.67 acre apartment development and the future development of additional R-4 lots on the 20 acre tract. The Baxter Apartments will be serviced by public water and sewer from the City of Bozeman. II. WATER DISTRIBUTION SYSTEM DESIGN The proposed water distribution system for the Baxter Apartments serves two purposes. The new water main will provide domestic water to the proposed 2.67 acre apartment complex and will provide tie in points for future development of the 20 acre site. The mains serving the apartment complex will utilize approximately 795 lineal feet of fl- inch Ductile Iron Class 51 water main forming a loop around the proposed 2.67 acre apartment development. This 8-inch main will tie to the existing City of Bozeman, 12- inch water main in Baxter Lane to the north and an existing 10" water main in the future N 271h Ave. to the west. Stub locations will be provided for future connections at the east end of West Winds Lane and at a future drive access on the south side of West Winds Lane. Each apartment building will be serviced by a 1 ''/z" Type "K", copper water service. Two existing hydrants along Baxter Lane will be extended to accommodate the proposed road widening. An additional hydrant is being proposed at the east end of West Winds Lane to meet the maximum spacing requirements. R-12005105-052 Dabney-Gould property iDesign Report FileslDesign Report.doc j Baxter Apartments August 31, 2005 Domestic water requirements for the apartment complex were determined using the fixture count method per the 2000 Uniform Plumbing Code. The total fixture count for the five buildings of the proposed development is 557 fixture units. This corresponds to a peak demand flow of 140 gpm. The services for the buildings were sized based on the peak demand flow for each building's fixture count. The fixture counts and peak flows are summarized in Appendix B. The fire flow is based on Appendix III-A of the 1994 Uniform Fire Code. The largest of the proposed buildings has a roof area of 148 feet by 55 feet or 8140 sq. ft. The building construction is Type V-N. From Table A-III-A-1 this corresponds to a fire flow of 2500 gpm. The design of the water mains which serve the apartment complex was accomplished using WaterCAD from Haestad Methods. The 8" DI loop was modeled using inputs that included the existing city water mains, the proposed 8" DI mains, and the available pressures that were received from the city water department. These pressures are detailed in a memo included in Appendix B. A diagram of the WaterCAD model is also included in Appendix B. The proposed pipe lengths and elevations were used for the modeling. Based on the model, the residual pressure at the south east corner of the site at the peak design flow of 2640 gpm is 71.3 psi. The available fire flow at a residual pressure of 20 psi is 3708 gpm with a total available flow at 20 psi residual of 3848 gpm. The maximum velocity in the proposed eight-inch main at the available fire flow of 3708 gpm is 12.6 feet per second. In addition to the mains serving the proposed apartments, approximately 640 feet of 12" DI water main will be installed in Tschache Lane. This main will serve future development on the remainder of the 20 acre tract as well as development to the east and development on the south side of Tschache Lane. This main will eventually tie to the existing 12" main in Tschache Lane near N 19`h Ave. There will be an additional stub location in the future Turbulence Lane to serve the future development on the remainder of the 20 acre tract. This 8" DI stub will tie into the existing 10" water main in N 27`h P:12005105-052 Dabney- Gould propertyiDesign Report FileslDesign Report.doc 2 Baxter Apartments August 31, 2005 Ave. These additional segments of water main will allow for future looping of the water mains for the remainder of the Baxter Apartments site. The addition of these loops in the future will improve the available flow to the site and provide adequate flows and pressures to meet the future water demand. Additional hydrant locations are proposed which meet the City of Bozeman spacing and location standards. One additional existing hydrant will need to be extended to accommodate the design of N 27'h Ave. A minimum ground cover of 6.5 feet will be maintained above all water mains and services. Concrete thrust blocks, Megalug joint restraints, or approved equivalent methods of joint restraint will be used during the installation of the water main and fittings per the City of Bozeman Design Standards, the Montana Public Works Standard Specifications, Fifth Edition (MPWSS), and the City of Bozeman Modifications to the MPWSS (City of Bozeman Mods). III. SEWER SYSTEM DESIGN The Baxter Apartments development will be served by an extension of the City of Bozeman sewer system. The extension will consist of approximately 1590 lineal feet of gravity flow 8 and 10-inch SDR 35 PVC sewer main and 8 manholes. All manholes on the project site will be the 48-inch diameter eccentric precast concrete style as per the City of Bozeman Modifications to the Montana Public Works Standard Specifications. The sewer main from the Baxter Apartments site will connect to the City of Bozeman 241nch asbestos concrete sewer main in Baxter Lane at a new 60"manhole. Each apartment building will be served by a 4-inch diameter SDR 35 PVC sewer service line. This sewer service line will be installed at a minimum slope of two percent. The Baxter Apartments site is approximately 20 acres. The City of Bozeman design standards were used to estimate a future wastewater flow. The design standard indicates a flow rate of 72 gallons per capita per day, an infiltration rate of 150 gallons per acre per P.12005105-052 Dabney-Gould property lDesign Report FilesOesign Report.doc 3 Baxter Apartments August 31, 2005 day and that the sewer pipe shall flow at no more than seventy-five percent full. Assuming an R-4 zoning, which corresponds to a population density of 12.19 capita per acre, the peak wastewater flow for the Baxter Apartments site was estimated to be 53 gpm. The calculation for this is included in Appendix C. As a conservative check, we assumed that the peak domestic water demand would all leave the site via the sewer main. We extrapolated the fixture counts for the proposed buildings over the 20 acre development. This yields a total design flow of approximately 360 gpm. The sewer main pipes were analyzed using FlowMaster by Haestad Methods. The analysis for the 8-inch sewer main assumed the following inputs: slope of 0.40% and a pipe material coefficient of 0.013 (PVC), a flow of 53 gpm and a pipe diameter of 8- inches. This analysis indicates that the 8-inch main will flow 27% full. Using the conservative flow of 360 gpm, a 10-inch pipe, a slope of 0.26% and a pipe material coefficient of 0.013 (PVC) indicates that the 10-inch main will flow 63% full. Based on this analysis, 10-inch PVC will be used for the portions of sewer that will eventually collect flow from the entire site and 8-inch main will be used on the stub to serve the portion of the future development between West Winds Lane and Turbulence Way. The sewer services were sized based on the assumption that the wastewater flow rate will equal the peak domestic water demand for the building. A hydraulic analysis was performed using FlowMaster on the service for the largest of the buildings. A flow rate of 60 gpm, a slope of 2.0%, a pipe material coefficient of 0.013 for PVC, and a pipe diameter of 4 inches were input. The 4 inch pipe will flow 50% full under these assumptions. IV. STORM WATER MASTER PLAN & FACILITIES DESIGN REPORT FOR FIRST PHASE OF DEVELOPMENT Existing Conditions The existing topography of the Baxter Apartments site is comprised of undeveloped farmland and native grasses. The drainage of the site flows generally northeast and into P:• 2005W5-052 Dabney-Gould propertylDesign Report FileslDesign Report.doc 4 Baxter Apartments August 31, 2005 an existing stream course and area of wetlands on the adjacent property to the east. The proposed development will change the runoff characteristics of the site. This report is based on the master plan as shown in Figure 1 in Appendix A and addresses the mitigation measures associated with these changes. This report also provides detailed hydrologic and hydraulic design and calculations for the storm sewer infrastructure associated with the first phase of development. Future development of Baxter Apartments site will need to address the specifics of storm water drainage associated with the individual sites and any additional changes made to the drainage patterns and storm water flows. Pre-development Calculations Pre-development run-off rates were calculated using the methodologies outlined in City of Bozeman Design Standards. The analysis was conducted for the 10-year storm. The entire site drains to the northeast corner and the time of concentration for the pre- development condition was calculated using Manning's Kinematic Solution based on an overall flow length of 1350 feet. The total overland time of concentration for the predevelopment condition is 45 minutes. This corresponds to a rainfall intensity of 0.77 in/hr. A pre-development runoff coefficient of 0.20 was used and a pre-development peak runoff of 3.10 cfs was calculated. The predevelopment contours are shown in Figure 2 in Appendix D. Post-development Drainage and Storm Water Facilities Design General The general drainage patterns for the post-developed site will remain generally the same with all site drainage flowing to the northeast corner of the site 20-acre site. Post- development runoff will be routed, using overland flow, curb and gutter as well as storm mains, to an on-site detention pond. The outlet for the pond will drain to the existing stream channel and wetland to the east in the ROW for Baxter Lane. Detailed P:12005105-052 Dabney- Gould propertylDesign Report FilesOesign Report.doc 5 Baxter Apartments August 31, 2005 calculations and supporting information for the design of the storm water facilities are provided in Appendix D. Storm Drainage Flow Patterns Post-development drainage patterns will differ from pre-development conditions due to the addition of impervious areas such as roads, sidewalks, and building roof areas. The drainage basins are shown on Figure 2 in Appendix D and are briefly described below. Drainage Area 1 — Drainage Area 1 encompasses the west portion of the site and has an area of 5.51 acres. This area includes the proposed N 27`h Ave. Drainage will flow as surface flow to curb and gutter at the roads. The gutter flow will enter the storm sewer main via an inlet in the low point of N 27`h Ave. Drainage Area 2 — Drainage Area 2 encompasses the eastern portion of the site and has an area of 11.88 acres. Under the pre-development conditions this area drains into the stream channel to the east. The drainage from the eastern portion of West Winds Lane will be collected via curb and gutter and directed via a swale into the detention pond. Under future development of the full 20 acre site, the remainder of this drainage area will drain via surface flow, curb and gutter, or storm sewer mains to a swale along the eastern portion of the site and into the detention pond. Drainage Area 3 — The proposed apartment development drains, via surface flow, to an inlet in the northwest corner of the parking area. This inlet drains via the storm sewer main into the proposed detention pond. For the design of the storm sewer mains, this area was taken as 2.70 acres. Hydrology The post-development run-off rates were calculated using the methodologies outlined in City of Bozeman Design Standards. A runoff coefficient ("C" value) of 0.5 for dense residential was assumed for the entire site for the post-development calculations. A time P:12005105-052 Dabney-Gould propertylDesign Report FilesOesign Report.doc Baxter Apartments August 31, 2005 of concentration was calculated based on the drainage pattern for Drainage Area#1. The flow path was taken as overland for 450 feet in the southwest comer of the site, followed by 880 feet of gutter flow along N 271h Ave, and finally 465 feet of pipe flow in the stone sewer main along Baxter Lane ending in the detention pond. A time of concentration of 28 minutes was calculated for this flow path. Rainfall intensity values corresponding to this time of concentration for the 10-year and 25-year storm are 1.05 in/hr and 1.27 in/hr respectively. Total flow values and storage requirements were calculated using these rainfall intensities, the C value, and the drainage basin area. Storm Sewer Main A new storm sewer system will be constructed along Baxter Lane. The system will consist of approximately 465 lineal feet of 15-inch and 18-inch RCP. The main will collect storm water from an inlet in N 27th Ave, an inlet in Baxter Lane and an inlet on the apartment development project. The storm sewer main will discharge to the detention pond. The storm sewer main has been designed to convey the calculated 25-year storm flows. Storm Sewer Inlets Three storm sewer inlets will be constructed as part of this project. They are located in N 271h Ave., in Baxter Lane, and on the apartment site. Each of these inlets has been designed to accept flow based on the 25-year storm. They have been spaced to limit flow in the gutter to 0.15 feet below the top back of curb. Detention Pond An on site detention pond will be used to limit flow from the site to the pre-development levels. The detention pond is located in the northeast corner of the 20-acre site. Discharge from the detention pond will drain via a 18"x 28.5" concrete arch pipe into the existing ditch in the ROW for Baxter Lane. The detention pond was designed to detain the 10-year storm, with provisions to handle the 25-year storm and allowance for the P:12005105-052 Dabney-Gould property0esign Report FileslDesign Report.doc 7 Baxter Apartments August 31, 2005 passage of the 100-yr flow. A spreadsheet detailing the calculations of the storage requirements and the provided storage is included in Appendix D. IV.
