Main St. Suite 206 PO Box 1793 Bozeman MT 59771 RE: WEST WINDS SW SUBDIVISION, BOZEMAN MT. SHPO Project #: 2017111305 Dear Mr. McSpadden: I have conducted a cultural resource file search for the above-cited project located in Section 2, T2S R5E. According to our records there have been no previously recorded sites within the designated search locales. However, there have been a few previously conducted cultural resource inventories done in the areas. I’ve attached a list of these reports. If you would like any further information regarding these reports, you may contact me at the number listed below. It is SHPO’s position that any structure over fifty years of age is considered historic and is potentially eligible for listing on the National Register of Historic Places. If any structures are to be altered and are over fifty years old we would recommend that they be recorded and a determination of their eligibility be made. Based on a previous inventory in the area we feel there is a low likelihood that cultural resources will be impacted. We therefore feel that a recommendation for a cultural resource inventory is unwarranted at this time. However, should structures need to be altered or if cultural materials be inadvertently discovered during this project we would ask that our office be contacted and the site investigated. If you have any further questions or comments you may contact me at (406) 444-7767 or by e-mail at dmurdo@mt.gov. I have attached an invoice for the file search. Thank you for consulting with us.

Our Postmaster is on vacation this week, 11/13-11/17/2017. I can give you an unofficial recommendation for placement of Centralize Box Units. I would suggest two locations. One location for the west half of the subdivision would be on the south side of Breeze Lane between lots 1 and 16 of Block 6. 2-16 CBU’s on a concrete pad 3ft deep, 6ft wide and 3 ½ inches thick, flush with the top back edge of the curb. Second location for the east half of the subdivision would be again on the south side of Breeze Lane between lots 1 and 16 of Block 5. 2-16 unit CBU’s and 1-12 unit CBU on a concrete pad 3ft deep, 9ft wide and 3 ½ inches thick, flush with the top back edge of the curb. Centralize Box Units and concrete pads to be furnished by the Developer. In the previous West Wind Condos development the project had be revised without my knowledge. So as for now this is my recommendation unless there are future changes made to the project. Any questions or concerns let me know. Thank you.

Main St. Suite 206 PO Box 1793 Bozeman, MT 59771 Via email: trever@haystackdevelopment.com Subject: West Winds SW Subdivision Dear Mr. McSpadden, Referencing your letter received November 9, 2017 concerning the evaluation of the subject development. Bozeman Public Schools would expect that the proposed 73 total lots could create up to 73 individual dwelling units, which would generate the following students: ♦ Pre-K to 5th 17 Students ♦ 6th to 8th 8 Students ♦ 9th to 12th 11 Students As of this date, the proposed development will be in the Emily Dickinson Elementary School, Chief Joseph Middle School and Bozeman High School attendance areas. Our elementary schools are nearing capacity, and the added enrolment for the proposed development could likely necessitate the need for Elementary #9. This need would be dependent on the successful passage of a future bond initiative for the design and construction for the school. The recent addition and expansion at Sacajawea Middle School will accommodate the proposed enrolment increase at the middle school level, as will the development of the second high school, which is currently underway. Population growth and demographic shifts in the future may necessitate boundary realignments to existing schools, which could modify the designated attending schools. Similarly, if a designated school attendance area’s student population exceeds the school’s capacity, attendance at an alternate school may be required. Infrastructure, such as sidewalks, should be constructed for the entire project irrespective of when actual homes are developed to provide a Safe Route to School pathway for students to safely traverse the developed and existing roadways. Our existing bus system can accommodate the estimated number of additional students. Please let us know if there are any changes to the proposed development as this could modify the above student projections.

As the City of Bozeman is providing all water supply, no water right permitting is required, and no groundwater exemptions are being used. I see the note about the borrow pit on the preliminary plat map, so that clears up the fate of the groundwater pit that is present. I have no other comments. Standard Language: In Clark Fork Coalition, et. al. v. DNRC, et. al., 2016 MT 229, 384 Mont. 503, 380 P.3d 771, the Montana Supreme Court concluded that the definition of “combined appropriation” in Admin. R. Mont. 36.12.101(13) was invalid. The Court reinstated the Department’s 1987 Rule defining “combined appropriation” as: “An appropriation of water from the same source aquifer by means of two or more groundwater developments, the purpose of which, in the department’s judgment, could have been accomplished by a single appropriation. Groundwater developments need not be physically connected nor have a common distribution system to be considered a “combined appropriation.” They can be separate developed springs or wells to separate parts of a project or development. Such wells and springs need not be developed simultaneously. They can be developed gradually or in increments. The amount of water appropriated from the entire project or development from these groundwater developments in the same source aquifer is the “combined appropriation.” Under this Rule, the Department interprets subdivisions that are pending before the Department of Environmental Quality for approval on October 17, 2014 or filed after that date to be a single project that can be accomplished by a single appropriation. Consequently, all wells in such a subdivision will be considered a “combined appropriation” for the purposes of Mont. Code Ann. 85-2-306. The only exception to this interpretation is that a subdivision which has received preliminary plat approval prior to October 17, 2014 will not be considered a project under the “combined appropriation” 1987 Rule; individual lots will still be evaluated under the 1987 Rule at the time of an application to the Department. 2015 Mont. Laws § 1, Ch. 221. This communication does not serve as a pre-approval for a water right.

This project has been broken up into two phases Phase 1 and Phase 2. The sizing of proposed water main Haystack Development October 26, 2017 Project: 16-003 Bozeman Office . 32 Discovery Drive .

Fax: (406) 582-5770 Page 2 extensions and analysis of available capacity of the existing water system for the West Winds Southwest development was completed originally completed on April 15, 2017. Minor revisions to the layout and dwelling units numbers are detailed below. The City of Bozeman Design Standards and Specifications Policy and the Montana Department of Environmental Quality Circular 1 were used for the basis of analysis and design for this report. 2 Overview The subject property is bounded by West Oak Street to the South, Davis Lane to the West, Winter Park Street to the north and Windward Avenue to the east. Figure 1 and 2 show the location of the site, and existing infrastructure around the site. The project is broken up into two major phases. The first phase to the north of Breeze Lane was completed in 2016. The second phase is a future subdivision south of Breeze Lane. Attached Sheet C0.5 shows the overall site layout and phasing for West Winds Southwest. The project site is located within the original West Winds Development and was included within portions of phase 4 and phase 5. The water distribution network was evaluated in the previous design reports by HKM. Previous reports found the distribution system would be able to provide more than enough volume and pressure to accommodate peak hour and fire flow demands. Rather than performing a detailed analysis of the existing and proposed systems, a more general approach was taken in order to demonstrate that adequate capacity will be available. In general, the site has high pressure. The site is bounded on two sides by existing 12 inch water mains and 8 inch mains on the other two sides. A total of 5 connections to the existing system will be made and 8 inch distribution mains will be looped throughout the site. Observed hydrant flow data provided by the City of Bozeman was used to develop a baseline for system pressure and capacity.

The base demand was calculated assuming 2.11 persons per unit and 170 gallons per person per day. The base demand is then 44,120 gallons per day; maximum hour is taken as 3 times the base demand producing a maximum hour demand of 132,360 gallons per day or 92 gpm. All structures within the site will be relatively small individual or duplex residential units. The fire flow requirement listed in Distribution System Requirements for Fire Protection – M31 from American Water Works Association is 1,400 gallons per minute for structures less than 11 feet apart. The needed fire flow is applicable to one and two-family dwellings for structures not exceeding two stories in height. A summary of the domestic and fire demands is shown in Table 3-1. The peak demand is thus calculated to be approximately 1,500 gallons per minute for fire and peak hour domestic demand as shown in the table below. Table 3-1 - Demand Summary Description Flow Rate (gpd) Flow Rate (gpm) Base Domestic Demand 44,120 31 Maximum Hour Demand NA 92 Fire Demand NA 1,400 Peak Demand (Fire Demand plus Max. Hour Demand) NA 1,492 4 Hydraulic Modeling and Analysis As shown on Figure 2.2, the site is currently bounded by 8 inch and 12 inch water lines on all four sides. Data from a flow test was provided by the City of Bozeman. The test was performed on September 28, 2015 at the intersection of Windward Ave. and West Oak Street – the southeast corner of the project site. The proximity of the hydrant tested to the site provides a good baseline for static and hydrant flow conditions. Table 4-1 provides a summary of the flow test. The test was performed on a 2.5 inch outlet using a pitot gauge; the pitot gauge reading was 54-psi at the outlet corresponding to 1,230 gpm. Table 4-1 - Observed Flow Test Pressure Reading Pressure (psi) Flow (gpm) Static Pressure 76 NA Residual Pressure 60 NA Pitot Pressure 54 1,230 Minimum system pressures under normal operating conditions must be greater than 35-psi. Past analyses from the 2005 Water Facility Plan and previous HKM design reports showed static pressures in this area of the pressure zone as high as 90 to 100-psi. While observed static pressures are lower, Haystack Development October 26, 2017 Project: 16-003 Bozeman Office . 32 Discovery Drive . Bozeman, Montana 59718 . Ph: (406) 582-0221 . Fax: (406) 582-5770 Page 6 adequate pressure is still provided for the base domestic demand condition. The lower observed pressures are more ideal for domestic use as 90 to 100-psi is higher than typically desired. The capacity of the system is demonstrated by the flow test showing that 60-psi was maintained with 1,230 gpm of flow. A simplified model of the proposed system was completed using EPANET 2.0 to evaluate head loss through the distribution system within the project site. A few assumptions were made for the distribution system surrounding the site to simplify the hydraulic model. The distribution system feeds the area from three general directions. The first is from the east by a 10-inch main within West Oak Street; the line size increases to 12-inch just west of Hunters Way. A pressure reducing valve (PRV) is located approximately 1,000 feet east of the intersection of Oak and 27th. The second line is a 10-inch that comes in from the west along West Oak Street. That 10-inch line in Oak is fed by a 10-inch line in Ferguson Avenue and through the looped distribution system within the subdivision directly south of Oak (and west of Davis Lane). The third area generally serving the site is from the south (east of Davis Lane) where mains within New Holland and Hunters Way connect to the main within Oak. The main within Durston Road to the south of the site acts as a manifold for areas to the north as many of the PRV’s are located just north of Durston. Several looped distribution lines feed from the south to the north. Figure 4 from the City of Bozeman Capital Planning mapper shows the overall existing distribution system and locations of PRVs. While this study does not consider adjacent domestic demands; the redundancy provided with multiple loops and connections in the area provides a stable network. The observed flow test and assumption of limited impact within the project site from adjacent areas was used to estimate pressures within the site.

Fax: (406) 582-5770 Page 7 The existing conditions model used for calibration is shown in Figure 5. The reservoir to the south of the project site represents the distribution lines serving the site from the PRVs. The system has been simplified with only two 8 inch lines feeding the main in Oak from the reservoir which should provide conservative results. The loss coefficient for the pipes from the reservoir were calibrated to match the observed flow test and residual pressure. A minor loss of 40 was applided to the two lines from the reservior for the calibration. This approach would not provide accurate results for a wide range of flows but provides an adequate model for the project base and fire flows which are relatively close to the observed flow rate during the flow test. An overview of the proposed condition model is shown on Figure 6. The model has been simplified to represent the project site only, not the surrounding system outside of the project site. However, the simplified model should provide a reasonable idea of capacity within the project site due to the complete loop around the site and the proximity of the flow test directly adjacent to the site.

Fax: (406) 582-5770 Page 8 maximum hour demand was divided equally to the 12 project nodes inside the project site (~7.7 gpm per node). These project nodes are numbered 15 through 26. Figure 4 – Project Water System Existing Conditions The fire demand of 1400-gpm was applied to all nodes throughout the proposed development to determine the lowest pressure case; maximum hour demands were maintained throughout the network. Placing the fire demand at node 24 (SW corner) produced the lowest system pressure, of 51.6- psi for the system. System pressures are above the minimum of 20-psi during fire flow and 35-psi during maximum hour demand. Haystack Development October 26, 2017 Project: 16-003 Bozeman Office . 32 Discovery Drive .

The lots shall provide a front porch or false façade, a sidewalk connection to each building, and the covenants shall prohibit the construction of fences unless constructed less than 4 feet tall with a coordinated design for all of the lots backing up to Oak Street, Baxter Lane, 27th Avenue and Davis Lane.” Preliminary Plat submittal shall clearly indicate the provisions to address this condition. This subdivision will be subject to the West Winds Declaration of Covenants, Conditions and Restrictions (West Winds Covenants). As a result, the requirements detailed above will be met through adherence to the provisions of Section 12.16 accordingly. A copy of the West Winds Covenants is provided as Appendix C of this application submittal. b. Lot 18 at Corner of Davis/Oak – show building envelope, appears questionable to be buildable lot with additional easement in place. Building envelopes for the lots within this subdivision are provided as part of the PUD Preliminary Plan application materials. In that application, an envelope for Lot 18 has been identified. Also included in those materials are conceptual building renderings that illustrate the feasibility of the building envelope for Lot 18. 6. Alleys are described as easements. They must be platted and dedicated with final plat. Layout does not show ownership lines corresponding with easements. Alley “A”, Alley “B” and Alley “C” are shown on the Preliminary Plat as dedicated alleyways the area for which is included in the total public right-of-way calculation. Individual lot lines correspond to the dedicated right-of-way boundaries. A copy of the Preliminary Plat is provided in Appendix A. 7. Describe the placement of irrigation equipment for public right of way and water source. A new irrigation well is proposed with this development. The well is located on the Northeast corner of the site between Lot 1 and Lot 2 of Block 4. New irrigation lines will be installed with all of the other subdivision improvements accordingly. 8. Where alleys are present, access to the lot shall be taken from the alley and not the adjacent street. Primary access to the individual lots is by way of the proposed alley rights-of-way where available. WEST WINDS SW SUBDIVISION PRELIMINARY PLAT APPLICATION 4 Planned Unit Development Advisory Comments 1. A planned unit development is required due to the lack of street frontage compliant with Section 38.24.090.B.2 and for the non-standard street/alley configuration. As discussed at the DRC meeting there are several alternatives which may make the PUD unnecessary. As mentioned, a PUD Preliminary Plan application has been submitted along with this subdivision application. The objective of the concurrent review is to provide context to this subdivision and demonstrate compliance with the existing relaxations approved as part of the West Winds Planned Community PUD and justify the additional relaxation noted above. 2. The original West Winds PUD was provided with an open space and park dedication up to a maximum number of dwellings. A revised accounting up to and including the development proposed with this plat must be provided with preliminary application. If additional open space or park land is necessary, staff supports cash or improvement-in- lieu to be used within the bounds of the overall West Winds PUD. A detailed parkland accounting and park improvements-in-lieu plan is provided in the Part II.3 below. Engineering Code Provisions Requiring Plan Corrections 1. BMC Section 32.23.180 states: the transfer of water rights or the payment of cash-in- lieu (CILO) of water rights shall be provided. The applicant must contact the City Engineering Department (Brian Heaston) for an analysis of CIL of water rights and pay any CIL of water rights due prior to site plan approval. Brian Heaston with the City Engineering Department has been contacted regarding the transfer of water rights, his correspondence is provided in Appendix D. In summary, his determination is that based on the amount of cash- in-lieu of water rights (CIL WR) provided with the West Winds Subdivision Phases 4 and 5, no additional CIL WR is necessary to offset the demands of the West Winds SW Subdivision. Advisory Comments 1. Bozeman Municipal Code (BMC) Section 32.24.060.B.4 states: All arterial and collector streets and intersections with arterial and collector streets shall operate at a minimum level of service “C” unless specifically exempted by this subsection. Level of service (LOS) values shall be determined by using the methods defined by the most recent WEST WINDS SW SUBDIVISION PRELIMINARY PLAT APPLICATION 5 edition of the Highway Capacity Manual. A development shall be approved only if the LOS requirements are met in the design year, which hall be a minimum of 15 years following the development application review or construction of mitigation measures if mitigation measures are required to maintain LOS. Intersections shall have a minimum acceptable LOS of “C” for the intersection as a whole. Three intersections within 0.5 miles of the project do not meet the minimum intersection LOS standard. These intersections include Baxter Lane and Davis Lane, Oak Street and Davis Lane, and 27th Avenue and Oak Street. These intersections must be upgraded prior to final plat approval. The City recently updated the relevant BMC section to allow for a waiver of the LOS requirement per specific conditions outlined in 38.24.060.B.4 However, the conditions of the waiver can not be met at this time for two of the intersections. A Traffic Impact Study has been prepared to analyze the potential impacts of this subdivision on the area street network. Generally, the study concluded that while the uses and densities proposed with this subdivision will generate a significant amount of traffic, recent upgrades to the network in this area have neutralized any deficiencies that may have been caused by this development. A copy of the Traffic Impact Study is provided as Appendix E of this application submittal. 2. The applicant must work with the City Engineering Department (Bill Stezner) and City Fire Department to develop a specific plan for addressing lots that do not front a City street. Addressing must be sufficient to clearly direct emergency services to lots that are located on alleys. The applicant must work out the addressing plan prior to preliminary plat approval, and the plan must be approved by the City Fire Department and City Engineering Department prior to preliminary plat approval. The applicant will work with the City Engineering Department and the City Fire Department throughout the preliminary plat application process to develop a specific plan for the lots that front Alley A and Alley B. 3. Drive accesses off alleys that have not yet been constructed must be constructed with a City Standard alley approach. Alternative drive accesses, such as was used in the SW Condos project, will not be allowed in any phasing of this project. Drive accesses off of the alleys have been designed in accordance to the City Standard alley approach. Details of these approaches are provided in the engineering plans located in Appendix B of this application submittal. 4. The extension of New Holland and the alley in Phase II must be constructed with temporary turn-arounds that must remain in place until Phase III in constructed. The temporary turn-around configuration must be approved by the City Fire Department prior to preliminary plat approval. WEST WINDS SW SUBDIVISION PRELIMINARY PLAT APPLICATION 6 Early plans to phase this subdivision have been changed and phasing is not proposed with this subdivision. 5. The applicant must review the proposed emergency access and turnaround at the end of Alley A with the City Fire Department and make any changes to the turnaround configuration to meet City Fire Department Requirements. This must be demonstrated prior to preliminary plat approval. The City Fire Department has reviewed the access and turnaround at the end of Alley A and a copy of the correspondence is provided in Appendix F of this application submittal. The applicant will continue to work with the City Fire Department throughout the preliminary plat application process. 6. BMC Section 32.23.030.A states: The developer shall install complete drainage facilities in accordance with the requirements of the state department of environmental quality and the city, and shall conform to any applicable facilities plan and the terms of any approved site specific stormwater control plan. The city’s requirements are contained in the design standards and specifications policy and the city modifications to state public works standard specifications, and by this reference these standards are incorporated into and made a part of these regulations. It appears that drainage facilities have not been taken into account with the draft pre- application plan. The applicant must demonstrate drainage facilities prior to preliminary plat approval. Storm water facilities have been designed in accordance with the applicable City of Bozeman and Montana Department of Environmental Quality requirements. Details of these facilities are provided in the engineering plans located in Appendix B of this application submittal. 7. BMC Section 32.25.020.M states: Snow removal storage areas shall be provided sufficient to store snow accumulation on site. Such areas shall not cause unsafe ingress/egress to the parking areas, shall not cause snow to be deposited on public rights-of-way, shall not include areas provided for required parking access and spaces, and shall not be placed in such a manner as to damage landscaping. Snow storage on-site is not sufficient in the proposed plan. The applicant must develop a snow storage plan and review that plan with the City Streets Superintendent (John VanDelinder). The applicant must obtain approval of a snow storage plan from the City Streets Superintendent prior to preliminary plat approval. A Snow Storage Plan is included as Appendix G of this application submittal. The applicant will work with the City Streets Superintendent throughout the preliminary plat application process to modify the plan accordingly. WEST WINDS SW SUBDIVISION PRELIMINARY PLAT APPLICATION 7 8. The project is located in the Far West Sewer Payback District. The applicant must contact the City Engineering Department (Katherine Maines) to review the required payment. The applicant must pay the required assessment prior to final plat approval. Katherine Maines of the City Engineering Department has been contacted regarding any required payment for the Far West Sewer Payback District. The applicant will continue to work with the City Engineering Department throughout the preliminary plat application process and will pay any necessary assessments prior to final plat approval. 9. The proposed development falls within a known area of high groundwater. No crawl spaces or basements may be constructed such that sump pumps are required to pump water from these spaces. Sump pumps are not allowed to be connected to the sanitary sewer system. Sump pumps are also not allowed to be connected to the drainage system unless capacity is designed into the drainage system to accept the pumped water. Water from sump pumps may not be discharged onto streets, such as into the curb and gutters where they may create a safety hazard for pedestrians and vehicles. Crawl space and other building construction considerations are included in the Geotechnical Report located in Appendix H of this application submittal. 10. If not already filed for the subject site, the applicant must provide and file with the County Clerk and Recorder’s office executed Waivers of Right to Protest Creation of Special Improvement Districts (SID’s) for the following: a. Street improvements to Davis Lane including paving, curb/gutter, sidewalk and storm drainage. b. Street improvements to Oak Street including paving, curb/gutter, sidewalk and storm drainage. c. Intersection improvements to Davis Lane and Oak Street. d. Intersection improvements to Baxter Lane and Davis Lane. e. Intersection improvements to N. 27th Avenue and Oak Street. f. Intersection improvements to Oak Street and Ferguson Avenue. The document filed must specify that in the event an SID is not utilized for the completion of these improvements, the developer agrees to participate in an alternate financing method for the completion of said improvements on a fair share, proportionate basis as determined by square footage of property, taxable valuation of the property, traffic contributions from the development, or a combination thereof. The applicant must provide a copy of the filed SID waiver prior to final plat approval. If necessary, each of the Waivers outlined above can be included on the face of the final plat, executed and recorded with the Gallatin County Clerk and Recorder accordingly. WEST WINDS SW SUBDIVISION PRELIMINARY PLAT APPLICATION 8 11. The applicant must provide a traffic impact study for the proposed project. A Traffic Impact Study has been completed and a copy is provided as Appendix E of this application submittal. Park 1. Documentation of compliance with the parkland dedication requirements of Section 32.24.020, BMC shall be provided with the final plat, preliminary plat layout (site plan) or individual development site plan. A table showing the parkland requirements for the overall subdivision or individual site and the method of meeting the parkland dedication shall be included on the site plan and conditions of approval sheet. The table shall explicitly state how much parkland credit was allocated for each parcel as approved and allocated in the development. The above referenced table is provided in Part II.3 that follows. The applicant will continue to work with the City Parks Department and the Recreation and Parks Advisory Board (RPAB) throughout the preliminary plat application process. 2. In addition, each PHASE of the development shall have a copy of the table included on the site plan covers sheet for each phase. The table must include the information below (sample table below). Early plans to phase this subdivision have been changed and phasing is not proposed with this subdivision. 3. The “west side” trail network is one of the longest and most heavily used trail systems in the network. There are several gaps in the trail network due to earlier failed developments (see below). We would support an improvements-in-lieu project to complete these gaps and refurbish the existing trails. I think we could assist with permitting for the watercourse crossings if necessary. The Park Plan included as part of this subdivision application includes the construction of a new connection to the Mainstreet to Mountains Trail system referenced above. A copy of the Park Plan is provided in Appendix I of this application submittal. This connection is proposed as an improvements-in-lieu alternative to the amount of parkland dedication that would be required to offset the increase in residential density. As noted above, this alternative could provide a greater benefit to the City of Bozeman Park and Trail network than a small land dedication in this area or cash-in-lieu approach as these improvements will contribute directly to the impacts associated with this subdivision. WEST WINDS SW SUBDIVISION PRELIMINARY PLAT APPLICATION 9 Part II Supplemental Information 1. Groundwater An extensive groundwater monitoring program was completed as part of the preparation of the 2016 Geotechnical Report provided in Appendix H of this application submittal. The findings of that report indicate relatively shallow groundwater depths ranging from approximately 5-feet to 12-feet. Measurements from 33 test pits located throughout the site were documented from February to April 2016. The Geotechnical Report includes high groundwater mitigation methods including a limitation on the depth of crawl spaces and the thoughtful selection of base course materials. Groundwater resources will be unaffected by this subdivision and degradation is unlikely. Beyond the potential for utilization as irrigation on landscaping features within the public right-of-way, groundwater will not be necessary to service the subdivision. Groundwater contamination can be avoided through the use of City of Bozeman services in lieu of on- site wastewater facilities. 2. Geology, Soils & Slopes Overall, the subject property is relatively flat and there are no geologic irregularities or unusual soil characteristics that would make this site less suitable for development than that of the surrounding properties. This site does include a recently reclaimed gravel pit. The reclamation of the pit included the utilization of native and imported fill material as recommended in the Geotechnical Report. Future, site specific, geotechnical investigation will be considered prior to the construction of streets, alleyways and buildings in those areas within the former extents of the pit site. A Geologic Map is provided as Figure 3. Geologic hazards, beyond those which exist throughout the general area in and around the City of Bozeman, are not anticipated. As a result, there are no protective measures proposed as part of this development. Soil conditions were analyzed as part of the site specific Geotechnical Report provided in Appendix H. Test pit measurements and material descriptions of the sites soil conditions are detailed throughout the report. Generalized soil types in the surrounding area are illustrated on Figure 4 based on data gathered from the Natural Resource and Conservation Service soil survey. Due to the unremarkable topography of the site, cuts and fills of more than 3-feet are not anticipated. A generalized slope graphic is provided as Figure 5. WEST WINDS SW SUBDIVISION PRELIMINARY PLAT APPLICATION 10 3. Agriculture There will not be any impact to agricultural lands as a result of this subdivision. The subject property is located within the corporate limits of the City of Bozeman. As part of the annexation of the property, a change in the intended uses of the property would have been considered by the governing body. At the time of annexation, it was determined that the property was a suitable candidate for the expansion of urban land uses and that development that is consistent with that objective was appropriate. 4. Agriculture Water User Facilities Agricultural water user facilities will be un-affected by this subdivision. There are no facilities located within the boundaries of this subdivision and no relocation or immediate impact on any nearby facilities is anticipated or proposed. 5. Water & Sewer Water supply and wastewater disposal facilities have been designed in accordance with the applicable City of Bozeman and Montana Department of Environmental Quality requirements. Details of these facilities are provided in the engineering plans located in Appendix B of this application submittal. 6. Stormwater Management Storm water treatment facilities have been designed in accordance with the applicable City of Bozeman and Montana Department of Environmental Quality requirements. Details of these facilities are provided in the engineering plans located in Appendix B of this application submittal. 7. Streets, Roads & Alleys This proposed subdivision will include a variety of access solutions, the most notable being the installation of New Holland Drive from the recently completed section of Breeze Lane to West Oak Street. Also included as part of this proposal is a series of alternative street sections that provide interior circulation throughout the site shown as Alleys A, B and C. The objective of these Alleys is to accommodate the internal access while addressing some of the unique characteristics of the property. As illustrated on Figure 6, each alley has elements of both traditional City of Bozeman standard alleys and local street sections in an effort to provide the most functional access possible. A Traffic Impact Study has been prepared to analyze the potential impacts of this subdivision on the area street network. Generally, the study concluded that while the uses and densities proposed with this subdivision will generate a significant amount of traffic, recent upgrades to the network in this area have neutralized any WEST WINDS SW SUBDIVISION PRELIMINARY PLAT APPLICATION 11 deficiencies that may have been caused by this development. A copy of the Traffic Impact Study is provided as Appendix E of this application submittal. In addition to vehicular accesses, this project provides for multi-modal transportation methods as well. Each Alley has a width of 32.5-feet and includes a 6.5-foot boulevard and a 5-foot sidewalk where it fronts a residential lot. Coupled with the relatively low volumes of traffic, the alley provides adequate bicycling opportunities and the sidewalks allow for safe pedestrian travel. This multi-modal network provides connections to the larger Mainstreet to Mountains trail system east of subject property including the link proposed with the Park Plan for this subdivision. 8. Utilities The utility providers for this subdivision have been notified of this subdivision request and given an opportunity to review the lot configuration and access layout for the project. The applicant will continue to work in conjunction with these providers to ensure adequate locations for the utility easements necessary for any future utility needs. Copies of the correspondence are provided in Appendix J of this application submittal. 9. Educational Facilities The impact on local educational services will be minimal. Local School Districts have been notified of this proposal and have indicated the district’s ability to accommodate the new students anticipated by this subdivision. A copy of the correspondence is provided in Appendix J of this application submittal. 10. Land Use As noted throughout this narrative, the land uses and densities proposed as part of this application are in accordance with the underlying zoning designation of R- 3 (Figure 7) and Future Land Use designation of Residential (Figure 8). 11. Parks & Recreation Facilities As noted in Part I of this application submittal, the Park Plan included as part of this subdivision application includes the construction of a new connection to the Mainstreet to Mountains Trail system referenced above. A copy of Park Plan is provided in Appendix I of this application submittal. As proposed, this connection would be an improvements-in-lieu alternative to the amount of parkland dedication that would be required to offset the increase in residential density. An accounting of the amount of parkland dedicated with the original platting of the parent parcels associated with this subdivision is provided in Table 1 below. Also included in Table 1 is the estimated increase in density, per WEST WINDS SW SUBDIVISION PRELIMINARY PLAT APPLICATION 12 lot, based on the approximate location of each of the lots to be created with this subdivision. Table 1 LOTS (AS PLATTED) ORIGINAL ALLOCATION LOTS (AS AMENDED) PROPOSED APPROPRIATION BALANCE Lot 1 Block 1 Phase 4 .54 AC. 18 Units Lot 3 .57 AC. 19 Units (.03) (1 Unit) Lot 2 Block 1 Phase 4 .54 AC. 18 Units Lot 2 .45 AC. 15 Units .09 3 Units Lot 1 Block 4 Phase 5 .48 AC. 16 Units Lot 4 1.17 AC. 39 Units (.69) (23 Units) TOTALS 1.56 AC. 52 Units 2.19 AC. 73 Units (.63) 21 Units The unit total in the “Proposed Appropriation” column is based on the 73 lots proposed with this subdivision and each row represents the underlying parent parcel associated, approximately, with each of those lots. Based on this historical context, Table 2 below is intended to provide an example tracking mechanism for the satisfaction of the parkland dedication required with this subdivision. As noted throughout this narrative, an improvements-in-lieu alternative is being proposed with this application. With that, the variables included in the Table 2 footnotes apply. Table 2 12. Lighting Plan This subdivision is located within the Special Lighting District No. 706. Plans and specifications for the lighting fixtures approved as part of that District are provided in Appendix N. Locations for each fixture are illustrated on the engineering plans in Appendix B.

WEST WINDS SW SUBDIVISION PRELIMINARY PLAT APPLICATION 13 13. Affordable Housing One of the fundamental objectives of this project is to provide housing that is accessible to a greater number of potential purchasers. This subdivision serves as a continuation of the West Winds SW Condominium project north of Breeze Lane. The vision has been to provide an array of housing types to better accommodate the needs of the buyer through a mix of ownership types. This project represents the completion of this goal by creating the townhouse lots and the single-family lots that will round out the product types. In addition to the relatively moderate pricing schedule anticipated for this development, this subdivision is subject to the requirements of Section 38.43.050 of the UDC. It is difficult to predict the project horizon at this point and this project, like all others, is at the mercy of the unpredictable housing market. In an effort to address these requirements at the subdivision application stage, a tracking method is being suggested that will allow for changes in each particular variable to be accounted for over the course of the development. The data reflected in Table 3 below is derived from information that is available as of this writing: Table 3 AFFORDABLE HOUSING TRACKING TABLE SUBDIVISION/PROJECT NAME: West Winds SW Subdivision Proposed Condominiums Townhomes Detached Total Projected Unit Total 42 31 73 Total Market Rate Units 29 15 44 Lower-Priced Units 3 4 7 Moderate-Priced Units 13 9 22 Required Condominiums Townhomes Detached Total Proposed Lower-Priced Units 3 4 7 Required Moderate- Priced Units 13 9 22 Fractional Requirement¹ Fractional CIL¹ Unit Types (Lots) Condominiums Townhomes Detached Total Studio/1 BR 2 BR 8 8 3+ BR 32 33 65 Studio 1BR/2 BR 3+ BR Lower-Priced Unit² $143,560.50 $174,388.32 $236,043.95 Moderate-Priced Unit² $197,509.18 $236,043.95 $313,113.48 ¹ If necessary and when approved as an alternative. ² a) Maximum price based on the AMI determined by the most current HUD adjustment. ² b) Assumes 0% down payment. ² c) Utilizes the AHO Administrative Manual for property taxes, homeowners insurance, PMI and HOA dues of $366.00/Month. ² d) Based on a 30-year mortgage and an interest rate of 4.5%. WEST WINDS SW SUBDIVISION PRELIMINARY PLAT APPLICATION 14 Based on this method, of the 73 lots created by this subdivision, 7 of those lots could be utilized for the construction of Lower-Priced homes and 22 would be provided to meet the Moderate-Priced category. What this table does not account for is the likelihood that these prices would within the general range of the remaining 44 Market Rate lots and the housing product constructed on them. As a result, the provision of “Affordable Housing” mandated by the UDC could, ultimately, appear less contrived in this neighborhood. As outlined in the footnotes of Table 3, this pricing assumes that there is no down payment for the home and is derived from several variables that will likely change over time. Those variables include, though are not limited to, HUD’s annual AMI determination for Gallatin County, a total monthly obligation of $366.00 per month for property taxes, home owners insurance, personal mortgage insurance and home owners association dues along with a 30-year mortgage with a 4.5% interest rate. WEST WINDS SW SUBDIVISION PRELIMINARY PLAT APPLICATION 15 Part III Summary In approving, conditionally approving, or denying a subdivision preliminary plat, the Bozeman City Commission shall consider whether the proposed subdivision complies with: a. Chapter 38 of the Bozeman Municipal Code This application is intended to satisfy the submittal requirements of Unified Development Code (Chapter 38, BMC) and those specifically requested as a result of the Pre-Application review process. b. Bozeman Community Plan (Growth Policy) This subdivision proposal meets the intent and standards of the underlying Growth Policy Land Use Designation of Residential. The uses and densities proposed with this application are consistent with those intended for this designation. c. The Montana Subdivision and Platting Act This preliminary plat application has been prepared with adherence to the Montana Subdivision and Platting Act. A Summary of Probable Impacts is provided below. 1. Effects on Agriculture There will not be any impact to agricultural lands as a result of this subdivision. The subject property is located within the corporate limits of the City of Bozeman. As part of the annexation of the property in 1997, a change in the intended uses of the property would have been considered by the governing body. At the time of annexation, it was determined that the property was a suitable candidate for the expansion of urban land uses and that development that is consistent with that objective was appropriate. 2. Effects on Agricultural Water User Facilities Agricultural water user facilities will be unaffected by this subdivision. There are no facilities located within the boundaries of this subdivision and no relocation or immediate impact on any nearby facilities is anticipated or proposed. 3. Effects on Local Services Water supply and wastewater treatment will be through connection to existing City of Bozeman Water and Sewer mains. Law enforcement and fire protection will be provided by the City of Bozeman Police and Fire Departments respectively. Development of this type is consistent with the types of uses anticipated for this WEST WINDS SW SUBDIVISION PRELIMINARY PLAT APPLICATION 16 area and therefore, should have a predictable impact on the area transportation network. The impact on local educational services will be minimal. Local School Districts have been notified of this proposal and have indicated the district’s ability to accommodate the new students anticipated by this subdivision. The utility providers for this subdivision have been provided the opportunity to review the lot configuration and access layout for this project. The applicant will continue to work in conjunction with these providers to ensure adequate locations for the utility easements necessary for any future utility needs. 4. Effects on the Natural Environment The Overall effect on the natural environment will be minimal. Any potential impacts will be mitigated to the greatest extent practical. Neither surface water nor ground water degradation is likely. Groundwater and surface water within this subdivision will be protected through the use of City of Bozeman water supply, wastewater disposal and storm water treatment systems which have been designed in accordance with all local and state requirements and will be reviewed and approved by the State of Montana. There are no threatened or endangered plant species known to exist within the subdivision. A Weed Management Plan has been reviewed and approved by the Gallatin County Weed Department. The plan addresses weed management and re- vegetation issues. A copy of the Weed Management Plan is provided in Appendix Q. Air quality will not be affected nor will riparian areas, floodplains and wetlands. 5. Effects on Wildlife and Wildlife Habitat Impacts beyond those which would be common in an urban residential neighborhood are not anticipated. The subdivision will not have any adverse effect on fisheries. There are no natural watercourses on site. Public access to public lands will not be affected by this subdivision. There are no public lands adjacent to the subject property. The subject property is located within the corporate limits of the City of Bozeman in an area that has been deemed appropriate for future urban growth. The subject property is located within the corporate limits of the City of Bozeman in an area that has been deemed appropriate for future urban growth. The Montana Department of Fish Wildlife and Parks was notified of this subdivision, a copy of the correspondence is provided in Appendix J. WEST WINDS SW SUBDIVISION PRELIMINARY PLAT APPLICATION 17 6. Effects on Public Health and Safety The subdivision site is located in an area that is not particularly susceptible to natural hazards. The subject property is not located within the 100-year floodplain and is not at any higher risk of hazards caused by seismic activity than other properties in the general area. d. Other adopted state and local ordinances including, but not limited to applicable zoning requirements This subdivision proposal meets the intent and standards of the underlying Zoning Designation of R-3. The uses and densities proposed as part of this subdivision are consistent with that zoning district.

The properties subject to this subdivision request are generally located at the corner of West Oak Street and Davis Lane as shown on Figure 1 and Figure 2. The properties are legally described as Lots 2, 3 & 4 of the Amended Plat of Lot 1 and Lot 2 of Block 1 and Lot 1 of Block 4 of West Winds Major Subdivision Phase 4 and Lot 1 of Block 3 and Lot 1 of Block 4 of West Winds Major Subdivision Phase 5. A copy of the Preliminary Plat is provided in Appendix A of this application submittal. The land uses and densities proposed as part of this application are in accordance with the underlying City of Bozeman zoning designation of R-3, the Bozeman Community Plan Future Land Use designation of Residential and the West Winds Planned Community PUD. Access to the individual lots will be provided by way of an extension of New Holland Drive, a City of Bozeman standard local street, and an interior network of alternative alleyways. Details regarding the accesses are provided in Part II.4 below and in the appendices referenced therein. Water supply, wastewater disposal and storm water treatment will be provided through the extension of City of Bozeman facilities. Plans and specifications for these extensions are included in the engineering plans provided in Appendix B. Note: Maps and Figures that are referenced throughout this narrative will be located at the back of the Part in which they are referenced. Pre-Application Responses Outlined below is a series of comments received from the City of Bozeman Department of Planning and Community Development, the City of Bozeman Engineering Department, the Development Review Committee and the Recreation and Parks Advisory Board as a result of their Pre-Application review. Also included are the Standard Code Provisions germane to this particular subdivision request as identified during the Pre-Application review. Responses to each comment and code provision are provided in bold print. General 1. The applicant is advised that unmet code provisions, or code provisions that are not specifically listed as conditions of approval, does not, in any way, create a waiver or other relaxation of the lawful requirements of the Bozeman Municipal Code or state law. WEST WINDS SW SUBDIVISION PRELIMINARY PLAT APPLICATION 2 The applicant acknowledges that they are subject to all lawful requirements of the Bozeman Municipal Code and/or state law. 2. Waivers – The DRC finds that the submittal material for groundwater, Geology/Soils/Slopes, parks, transportation, and affordable housing are required. All other supplemental plat materials are waived. Details regarding Groundwater, Geology, Soils and Slopes, Parks and Recreational Facilities, Transportation, and Affordable Housing, along with any relevant supplemental reference materials, are provided in Part II and the Appendices of this application submittal. Planning Subdivision Advisory Comments 1. Phasing – Phase 1 acceptable as proposed, Phase 2 leaves long dead ends – turn- arounds are needed or revise Phase 3 to include balance of New Holland. Applicant may consolidate all phases to a single phase if desired. Early plans to phase this subdivision have been changed and phasing is not proposed with this subdivision. 2. Block numbers must be added to the plat. Block numbers have been added to the preliminary plat. A copy of the preliminary plat is provided as Appendix A of this application submittal. 3. Covenants shall not prohibit use of the larger corner lots for two-household residences or accessory dwellings. Covenants will not prohibit the use of the larger corner lots for two-household residences and/or accessory dwellings. Furthermore, as detailed in the concurrent PUD Preliminary Plan application, those lots are identified as multi- family lots. 4. Compliance with the original PUD as amended and prior subdivision conditions of approval must be demonstrated with the preliminary plat submittal. Compliance with the West Winds Planned Community PUD and applicable conditions of subdivision approval are detailed throughout this application narrative and the supplementary materials provided in the Appendix. WEST WINDS SW SUBDIVISION PRELIMINARY PLAT APPLICATION 3 5. Design related – a. The West Winds PUD contains the following condition: “The Covenants and Design Guidelines must state the means in which building orientation will be mitigated along the arterial and collector streets. The lots shall provide a front porch or false façade, a sidewalk connection to each building, and the covenants shall prohibit the construction of fences unless constructed less than 4 feet tall with a coordinated design for all of the lots backing up to Oak Street, Baxter Lane, 27th Avenue and Davis Lane.” Preliminary Plat submittal shall clearly indicate the provisions to address this condition. This subdivision will be subject to the West Winds Declaration of Covenants, Conditions and Restrictions (West Winds Covenants). As a result, the requirements detailed above will be met through adherence to the provisions of Section 12.16 accordingly. A copy of the West Winds Covenants is provided as Appendix C of this application submittal. b. Lot 18 at Corner of Davis/Oak – show building envelope, appears questionable to be buildable lot with additional easement in place. Lot 18, as included in the Pre-Application Plan, has been removed. 6. Alleys are described as easements. They must be platted and dedicated with final plat. Layout does not show ownership lines corresponding with easements. “Flurry Byway”, “Mistral Byway” and “Zephyr Byway” are shown on the Preliminary Plat as dedicated alleyways the area for which is included in the total public right-of-way calculation. Individual lot lines correspond to the dedicated right-of-way boundaries. A copy of the Preliminary Plat is provided in Appendix A. 7. Describe the placement of irrigation equipment for public right of way and water source. A new irrigation well is proposed with this development. The well is located on the Northeast corner of the site between Lot 1 and Lot 2 of Block 4. New irrigation lines will be installed with all of the other subdivision improvements accordingly. 8. Where alleys are present, access to the lot shall be taken from the alley and not the adjacent street. Primary access to the individual lots is by way of the proposed alley rights-of-way where available. WEST WINDS SW SUBDIVISION PRELIMINARY PLAT APPLICATION 4 Planned Unit Development Advisory Comments 1. A planned unit development is required due to the lack of street frontage compliant with Section 38.24.090.B.2 and for the non-standard street/alley configuration. As discussed at the DRC meeting there are several alternatives which may make the PUD unnecessary. As mentioned, a PUD Preliminary Plan application has been submitted along with this subdivision application. The objective of the concurrent review is to provide context to this subdivision and demonstrate compliance with the existing relaxations approved as part of the West Winds Planned Community PUD and justify the additional relaxation noted above. 2. The original West Winds PUD was provided with an open space and park dedication up to a maximum number of dwellings. A revised accounting up to and including the development proposed with this plat must be provided with preliminary application. If additional open space or park land is necessary, staff supports cash or improvement-in- lieu to be used within the bounds of the overall West Winds PUD. A detailed parkland accounting and park improvements-in-lieu plan is provided in the Part II.3 below. Engineering Code Provisions Requiring Plan Corrections 1. BMC Section 32.23.180 states: the transfer of water rights or the payment of cash-in- lieu (CILO) of water rights shall be provided. The applicant must contact the City Engineering Department (Brian Heaston) for an analysis of CIL of water rights and pay any CIL of water rights due prior to site plan approval. Brian Heaston with the City Engineering Department has been contacted regarding the transfer of water rights, his correspondence is provided in Appendix D. In summary, his determination is that based on the amount of cash- in-lieu of water rights (CIL WR) provided with the West Winds Subdivision Phases 4 and 5, no additional CIL WR is necessary to offset the demands of the West Winds SW Subdivision. Advisory Comments 1. Bozeman Municipal Code (BMC) Section 32.24.060.B.4 states: All arterial and collector streets and intersections with arterial and collector streets shall operate at a minimum level of service “C” unless specifically exempted by this subsection. Level of service (LOS) values shall be determined by using the methods defined by the most recent WEST WINDS SW SUBDIVISION PRELIMINARY PLAT APPLICATION 5 edition of the Highway Capacity Manual. A development shall be approved only if the LOS requirements are met in the design year, which hall be a minimum of 15 years following the development application review or construction of mitigation measures if mitigation measures are required to maintain LOS. Intersections shall have a minimum acceptable LOS of “C” for the intersection as a whole. Three intersections within 0.5 miles of the project do not meet the minimum intersection LOS standard. These intersections include Baxter Lane and Davis Lane, Oak Street and Davis Lane, and 27th Avenue and Oak Street. These intersections must be upgraded prior to final plat approval. The City recently updated the relevant BMC section to allow for a waiver of the LOS requirement per specific conditions outlined in 38.24.060.B.4 However, the conditions of the waiver can not be met at this time for two of the intersections. A Traffic Impact Study has been prepared to analyze the potential impacts of this subdivision on the area street network. Generally, the study concluded that while the uses and densities proposed with this subdivision will generate a significant amount of traffic, recent upgrades to the network in this area have neutralized any deficiencies that may have been caused by this development. A copy of the Traffic Impact Study is provided as Appendix E of this application submittal. 2. The applicant must work with the City Engineering Department (Bill Stezner) and City Fire Department to develop a specific plan for addressing lots that do not front a City street. Addressing must be sufficient to clearly direct emergency services to lots that are located on alleys. The applicant must work out the addressing plan prior to preliminary plat approval, and the plan must be approved by the City Fire Department and City Engineering Department prior to preliminary plat approval. The applicant will work with the City Engineering Department and the City Fire Department throughout the preliminary plat application process to develop a specific plan for the lots that front Flurry Byway and Zephyr Byway. 3. Drive accesses off alleys that have not yet been constructed must be constructed with a City Standard alley approach. Alternative drive accesses, such as was used in the SW Condos project, will not be allowed in any phasing of this project. Drive accesses off of the alleys have been designed in accordance to the City Standard alley approach. Details of these approaches are provided in the engineering plans located in Appendix B of this application submittal. 4. The extension of New Holland and the alley in Phase II must be constructed with temporary turn-arounds that must remain in place until Phase III in constructed. The temporary turn-around configuration must be approved by the City Fire Department prior to preliminary plat approval. WEST WINDS SW SUBDIVISION PRELIMINARY PLAT APPLICATION 6 Early plans to phase this subdivision have been changed and phasing is not proposed with this subdivision. 5. The applicant must review the proposed emergency access and turnaround at the end of Alley A with the City Fire Department and make any changes to the turnaround configuration to meet City Fire Department Requirements. This must be demonstrated prior to preliminary plat approval. The City Fire Department reviewed the access and turnaround at the end of Alley A and a copy of the correspondence is provided in Appendix F of this application submittal. Based on a subsequent review by the Development Review Committee, the turnaround configuration has been removed. The applicant will continue to work with the City Fire Department throughout the preliminary plat application process. 6. BMC Section 32.23.030.A states: The developer shall install complete drainage facilities in accordance with the requirements of the state department of environmental quality and the city and shall conform to any applicable facilities plan and the terms of any approved site specific stormwater control plan. The city’s requirements are contained in the design standards and specifications policy and the city modifications to state public works standard specifications, and by this reference these standards are incorporated into and made a part of these regulations. It appears that drainage facilities have not been taken into account with the draft pre- application plan. The applicant must demonstrate drainage facilities prior to preliminary plat approval. Storm water facilities have been designed in accordance with the applicable City of Bozeman and Montana Department of Environmental Quality requirements. Details of these facilities are provided in the engineering plans located in Appendix B of this application submittal. 7. BMC Section 32.25.020.M states: Snow removal storage areas shall be provided sufficient to store snow accumulation on site. Such areas shall not cause unsafe ingress/egress to the parking areas, shall not cause snow to be deposited on public rights-of-way, shall not include areas provided for required parking access and spaces, and shall not be placed in such a manner as to damage landscaping. Snow storage on-site is not sufficient in the proposed plan. The applicant must develop a snow storage plan and review that plan with the City Streets Superintendent (John VanDelinder). The applicant must obtain approval of a snow storage plan from the City Streets Superintendent prior to preliminary plat approval. A Snow Storage Plan is included as Appendix G of this application submittal. Based on a subsequent review by the Development Review Committee, area has WEST WINDS SW SUBDIVISION PRELIMINARY PLAT APPLICATION 7 been added to Open Space 1 in an effort to accommodate additional snow storage. The applicant will work with the City Streets Superintendent throughout the preliminary plat application process to further modify the plan if necessary. 8. The project is located in the Far West Sewer Payback District. The applicant must contact the City Engineering Department (Katherine Maines) to review the required payment. The applicant must pay the required assessment prior to final plat approval. Katherine Maines of the City Engineering Department has been contacted regarding any required payment for the Far West Sewer Payback District. The applicant will continue to work with the City Engineering Department throughout the preliminary plat application process and will pay any necessary assessments prior to final plat approval. 9. The proposed development falls within a known area of high groundwater. No crawl spaces or basements may be constructed such that sump pumps are required to pump water from these spaces. Sump pumps are not allowed to be connected to the sanitary sewer system. Sump pumps are also not allowed to be connected to the drainage system unless capacity is designed into the drainage system to accept the pumped water. Water from sump pumps may not be discharged onto streets, such as into the curb and gutters where they may create a safety hazard for pedestrians and vehicles. Crawl space and other building construction considerations are included in the Geotechnical Report located in Appendix H of this application submittal. 10. If not already filed for the subject site, the applicant must provide and file with the County Clerk and Recorder’s office executed Waivers of Right to Protest Creation of Special Improvement Districts (SID’s) for the following: a. Street improvements to Davis Lane including paving, curb/gutter, sidewalk and storm drainage. b. Street improvements to Oak Street including paving, curb/gutter, sidewalk and storm drainage. c. Intersection improvements to Davis Lane and Oak Street. d. Intersection improvements to Baxter Lane and Davis Lane. e. Intersection improvements to N. 27th Avenue and Oak Street. f. Intersection improvements to Oak Street and Ferguson Avenue. The document filed must specify that in the event an SID is not utilized for the completion of these improvements, the developer agrees to participate in an alternate financing method for the completion of said improvements on a fair share, proportionate basis as determined by square footage of property, taxable valuation of the property, traffic contributions from the development, or a combination thereof. The applicant must provide a copy of the filed SID waiver prior to final plat approval. WEST WINDS SW SUBDIVISION PRELIMINARY PLAT APPLICATION 8 If necessary, each of the Waivers outlined above can be included on the face of the final plat, executed and recorded with the Gallatin County Clerk and Recorder accordingly. 11. The applicant must provide a traffic impact study for the proposed project. A Traffic Impact Study has been completed and a copy is provided as Appendix E of this application submittal. Park 1. Documentation of compliance with the parkland dedication requirements of Section 32.24.020, BMC shall be provided with the final plat, preliminary plat layout (site plan) or individual development site plan. A table showing the parkland requirements for the overall subdivision or individual site and the method of meeting the parkland dedication shall be included on the site plan and conditions of approval sheet. The table shall explicitly state how much parkland credit was allocated for each parcel as approved and allocated in the development. The above referenced table is provided in Part II.3 that follows. The applicant will continue to work with the City Parks Department and the Recreation and Parks Advisory Board (RPAB) throughout the preliminary plat application process. 2. In addition, each PHASE of the development shall have a copy of the table included on the site plan covers sheet for each phase. The table must include the information below (sample table below). Early plans to phase this subdivision have been changed and phasing is not proposed with this subdivision. 3. The “west side” trail network is one of the longest and most heavily used trail systems in the network. There are several gaps in the trail network due to earlier failed developments (see below). We would support an improvements-in-lieu project to complete these gaps and refurbish the existing trails. I think we could assist with permitting for the watercourse crossings if necessary. The Park Plan included as part of this subdivision application includes the construction of a new connection to the Mainstreet to Mountains Trail system referenced above. A copy of the Park Plan is provided in Appendix I of this application submittal. This connection is proposed as an improvements-in-lieu alternative to the amount of parkland dedication that would be required to offset the increase in residential density. As noted above, this alternative could provide a greater benefit to the City of Bozeman Park and Trail network than a small land WEST WINDS SW SUBDIVISION PRELIMINARY PLAT APPLICATION 9 dedication in this area as these improvements will contribute directly to the impacts associated with this subdivision. As noted in Table 2, additional cash-in- lieu has been requested to offset any discrepancies between the required land donation and the improvements-in-lieu proposed. WEST WINDS SW SUBDIVISION PRELIMINARY PLAT APPLICATION 10 Part II Supplemental Information 1. Groundwater An extensive groundwater monitoring program was completed as part of the preparation of the 2016 Geotechnical Report provided in Appendix H of this application submittal. The findings of that report indicate relatively shallow groundwater depths ranging from approximately 5-feet to 12-feet. Measurements from 33 test pits located throughout the site were documented from February to April 2016. The Geotechnical Report includes high groundwater mitigation methods including a limitation on the depth of crawl spaces and the thoughtful selection of base course materials. Groundwater resources will be unaffected by this subdivision and degradation is unlikely. Beyond the potential for utilization as irrigation on landscaping features within the public right-of-way, groundwater will not be necessary to service the subdivision. Groundwater contamination can be avoided through the use of City of Bozeman services in lieu of on- site wastewater facilities. 2. Geology, Soils & Slopes Overall, the subject property is relatively flat and there are no geologic irregularities or unusual soil characteristics that would make this site less suitable for development than that of the surrounding properties. This site does include a recently reclaimed gravel pit. The reclamation of the pit included the utilization of native and imported fill material as recommended in the Geotechnical Report. Future, site specific, geotechnical investigation will be considered prior to the construction of streets, alleyways and buildings in those areas within the former extents of the pit site. A Geologic Map is provided as Figure 3. Geologic hazards, beyond those which exist throughout the general area in and around the City of Bozeman, are not anticipated. As a result, there are no protective measures proposed as part of this development. Soil conditions were analyzed as part of the site specific Geotechnical Report provided in Appendix H. Test pit measurements and material descriptions of the sites soil conditions are detailed throughout the report. Generalized soil types in the surrounding area are illustrated on Figure 4 based on data gathered from the Natural Resource and Conservation Service soil survey. Due to the unremarkable topography of the site, cuts and fills of more than 3-feet are not anticipated. A generalized slope graphic is provided as Figure 5. WEST WINDS SW SUBDIVISION PRELIMINARY PLAT APPLICATION 11 3. Agriculture There will not be any impact to agricultural lands as a result of this subdivision. The subject property is located within the corporate limits of the City of Bozeman. As part of the annexation of the property, a change in the intended uses of the property would have been considered by the governing body. At the time of annexation, it was determined that the property was a suitable candidate for the expansion of urban land uses and that development that is consistent with that objective was appropriate. 4. Agriculture Water User Facilities Agricultural water user facilities will be un-affected by this subdivision. There are no facilities located within the boundaries of this subdivision and no relocation or immediate impact on any nearby facilities is anticipated or proposed. 5. Water & Sewer Water supply and wastewater disposal facilities have been designed in accordance with the applicable City of Bozeman and Montana Department of Environmental Quality requirements. Details of these facilities are provided in the engineering plans located in Appendix B of this application submittal. 6. Stormwater Management Storm water treatment facilities have been designed in accordance with the applicable City of Bozeman and Montana Department of Environmental Quality requirements. Details of these facilities are provided in the engineering plans located in Appendix B of this application submittal. 7. Streets, Roads & Alleys This proposed subdivision will include a variety of access solutions, the most notable being the installation of New Holland Drive from the recently completed section of Breeze Lane to West Oak Street. Also included as part of this proposal is a series of alternative street sections that provide interior circulation throughout the site shown as Flurry Byway, Mistral Byway and Zephyr Byway. The objective of these alternative byways is to accommodate the internal access while addressing some of the unique characteristics of the property. As illustrated on Figure 6, each byway has elements of both traditional City of Bozeman standard alleys and local street sections in an effort to provide the most functional access possible. A Traffic Impact Study has been prepared to analyze the potential impacts of this subdivision on the area street network. Generally, the study concluded that while the uses and densities proposed with this subdivision will generate a significant amount of traffic, recent upgrades to the network in this area have neutralized any WEST WINDS SW SUBDIVISION PRELIMINARY PLAT APPLICATION 12 deficiencies that may have been caused by this development. A copy of the Traffic Impact Study is provided as Appendix E of this application submittal. In addition to vehicular accesses, this project provides for multi-modal transportation methods as well. Each byway has a width of 32.5-feet and includes a 6.5-foot boulevard and a 5-foot sidewalk where it fronts a residential lot. Coupled with the relatively low volumes of traffic, the byway provides adequate bicycling opportunities and the sidewalks allow for safe pedestrian travel. This multi-modal network provides connections to the larger Mainstreet to Mountains trail system east of subject property including the link proposed with the Park Plan for this subdivision. 8. Utilities The utility providers for this subdivision have been notified of this subdivision request and given an opportunity to review the lot configuration and access layout for the project. The applicant will continue to work in conjunction with these providers to ensure adequate locations for the utility easements necessary for any future utility needs. Copies of the correspondence are provided in Appendix J of this application submittal. 9. Educational Facilities The impact on local educational services will be minimal. Local School Districts have been notified of this proposal and have indicated the district’s ability to accommodate the new students anticipated by this subdivision. A copy of the correspondence is provided in Appendix J of this application submittal. 10. Land Use As noted throughout this narrative, the land uses and densities proposed as part of this application are in accordance with the underlying zoning designation of R- 3 (Figure 7) and Future Land Use designation of Residential (Figure 8). 11. Parks & Recreation Facilities As noted in Part I of this application submittal, the Park Plan included as part of this subdivision application includes the construction of a new connection to the Mainstreet to Mountains Trail system referenced above. A copy of Park Plan is provided in Appendix I of this application submittal. As proposed, this connection would be an improvements-in-lieu alternative to the amount of parkland dedication that would be required to offset the increase in residential density. An accounting of the amount of parkland dedicated with the original platting of the parent parcels associated with this subdivision is provided in Table 1 below. Also included in Table 1 is the estimated increase in density, per WEST WINDS SW SUBDIVISION PRELIMINARY PLAT APPLICATION 13 lot, based on the approximate location of each of the lots to be created with this subdivision. Table 1 LOTS (AS PLATTED) ORIGINAL ALLOCATION LOTS (AS AMENDED) PROPOSED APPROPRIATION BALANCE Lot 1 Block 1 Phase 4 .54 AC. 18 Units Lot 3 .66 AC. 22 Units (.12) (4 Units) Lot 2 Block 1 Phase 4 .54 AC. 18 Units Lot 2 .54 AC. 18 Units .00 0 Units Lot 1 Block 4 Phase 5 .48 AC. 16 Units Lot 4 1.26 AC. 42 Units (.78) (26 Units) TOTALS 1.56 AC. 52 Units 2.46 AC. 82 Units (.90) (30 Units) The unit total in the “Proposed Appropriation” column is based on the 72 lots proposed with the West Winds SW Subdivision and each row represents the underlying parent parcel associated, approximately, with each of those lots. This scenario assumes a maximum density with the utilization of larger corner lots as a series of condominium duplexes. Should these lots be utilized as single-family lots, the increase in density would be limited to .63 acres or 21 Units. Based on this historical context, Table 2 below is intended to provide an example tracking mechanism for the satisfaction of the parkland dedication required with this subdivision. As noted throughout this narrative, an improvements-in-lieu alternative is being proposed with this application. With that, the variables included in the Table 2 footnotes apply. Table 2 PUBLIC PARKLAND DEDICATION TRACKING TABLE SUBDIVISION/PROJECT NAME: West Winds SW Subdivision Number of Residential Units/Lots: 82 Total Parkland Dedicated w/ Subdivision (Acres) Cash-in-Lieu Required¹ Improvements-in- Lieu Required¹ Overall Project Balance (Acres) Parkland Required 2.46 1.56 .90 Cash-in-Lieu Proposed¹ $620.00 $620.00 Improvements-in- Lieu Proposed¹ $33,130.00 $33,750.00 0 ¹ If necessary and when approved as an alternative to land dedication. ² Based on $37,500.00/Acre CIL estimate. WEST WINDS SW SUBDIVISION PRELIMINARY PLAT APPLICATION 14 12. Lighting Plan This subdivision is located within the Special Lighting District No. 706. Plans and specifications for the lighting fixtures approved as part of that District are provided in Appendix N. Locations for each fixture are illustrated on the engineering plans in Appendix B. 13. Affordable Housing One of the fundamental objectives of this project is to provide housing that is accessible to a greater number of potential purchasers. This subdivision serves as a continuation of the West Winds SW Condominium project north of Breeze Lane. The vision has been to provide an array of housing types to better accommodate the needs of the buyer through a mix of ownership types. This project represents the completion of this goal by creating the townhouse lots and the single-family lots that will round out the product types. In addition to the relatively moderate pricing schedule anticipated for this development, this subdivision is subject to the requirements of Section 38.43.050 of the UDC. It is difficult to predict the project horizon at this point and this project, like all others, is at the mercy of the unpredictable housing market. In an effort to address these requirements at the subdivision application stage, a tracking method is being suggested that will allow for changes in each particular variable to be accounted for over the course of the development. The data reflected in Table 3 below is derived from information that is available as of this writing: WEST WINDS SW SUBDIVISION PRELIMINARY PLAT APPLICATION 15 Table 3 AFFORDABLE HOUSING TRACKING TABLE SUBDIVISION/PROJECT NAME: West Winds SW Subdivision Proposed Condominiums Townhomes Detached Total Projected Unit Total 40 36 76 Total Market Rate Units 26 27 53 Lower-Priced Units Moderate-Priced Units 14 9 23 Required Condominiums Townhomes Detached Total Proposed Lower-Priced Units Required Moderate- Priced Units 14 9 23 Fractional Requirement¹ Fractional CIL¹ Unit Types (Lots) Condominiums Townhomes Detached Total Studio/1 BR 2 BR 9 9 3+ BR 14 14 Studio 1BR/2 BR 3+ BR Lower-Priced Unit² $143,560.50 $174,388.32 $236,043.95 Moderate-Priced Unit² $197,509.18 $236,043.95 $313,113.48 ¹ If necessary and when approved as an alternative. ² a) Maximum price based on the AMI determined by the most current HUD adjustment. ² b) Assumes 0% down payment. ² c) Utilizes the AHO Administrative Manual for property taxes, homeowners insurance, PMI and HOA dues of $366.00/Month. ² d) Based on a 30-year mortgage and an interest rate of 4.5%. Based on this method, 23 units, located on and throughout the 72 lots created by this subdivision, would be provided to meet the Moderate-Priced category. What this table does not account for is the likelihood that these prices would be within the general range of the remaining 53 Market Rate units/lots and the housing product constructed on them. As a result, the provision of “Affordable Housing” mandated by the UDC could, ultimately, appear less contrived in this neighborhood. As outlined in the footnotes of Table 3, this pricing assumes that there is no down payment for the home and is derived from several variables that will likely change over time. Those variables include, though are not limited to, HUD’s annual AMI determination for Gallatin County, a total monthly obligation of $366.00 per month for property taxes, home owners insurance, personal mortgage insurance and home owners association dues along with a 30-year mortgage with a 4.5% interest rate. WEST WINDS SW SUBDIVISION PRELIMINARY PLAT APPLICATION 16 Part III Summary In approving, conditionally approving, or denying a subdivision preliminary plat, the Bozeman City Commission shall consider whether the proposed subdivision complies with: a. Chapter 38 of the Bozeman Municipal Code This application is intended to satisfy the submittal requirements of Unified Development Code (Chapter 38, BMC) and those specifically requested as a result of the Pre-Application review process. b. Bozeman Community Plan (Growth Policy) This subdivision proposal meets the intent and standards of the underlying Growth Policy Land Use Designation of Residential. The uses and densities proposed with this application are consistent with those intended for this designation. c. The Montana Subdivision and Platting Act This preliminary plat application has been prepared with adherence to the Montana Subdivision and Platting Act. A Summary of Probable Impacts is provided below. 1. Effects on Agriculture There will not be any impact to agricultural lands as a result of this subdivision. The subject property is located within the corporate limits of the City of Bozeman. As part of the annexation of the property in 1997, a change in the intended uses of the property would have been considered by the governing body. At the time of annexation, it was determined that the property was a suitable candidate for the expansion of urban land uses and that development that is consistent with that objective was appropriate. 2. Effects on Agricultural Water User Facilities Agricultural water user facilities will be unaffected by this subdivision. There are no facilities located within the boundaries of this subdivision and no relocation or immediate impact on any nearby facilities is anticipated or proposed. 3. Effects on Local Services Water supply and wastewater treatment will be through connection to existing City of Bozeman Water and Sewer mains. Law enforcement and fire protection will be provided by the City of Bozeman Police and Fire Departments respectively. Development of this type is consistent with the types of uses anticipated for this WEST WINDS SW SUBDIVISION PRELIMINARY PLAT APPLICATION 17 area and therefore, should have a predictable impact on the area transportation network. The impact on local educational services will be minimal. Local School Districts have been notified of this proposal and have indicated the district’s ability to accommodate the new students anticipated by this subdivision. The utility providers for this subdivision have been provided the opportunity to review the lot configuration and access layout for this project. The applicant will continue to work in conjunction with these providers to ensure adequate locations for the utility easements necessary for any future utility needs. 4. Effects on the Natural Environment The Overall effect on the natural environment will be minimal. Any potential impacts will be mitigated to the greatest extent practical. Neither surface water nor ground water degradation are likely. Groundwater and surface water within this subdivision will be protected through the use of City of Bozeman water supply, wastewater disposal and storm water treatment systems which have been designed in accordance with all local and state requirements and will be reviewed and approved by the State of Montana. There are no threatened or endangered plant species known to exist within the subdivision. A Weed Management Plan has been reviewed and approved by the Gallatin County Weed Department. The plan addresses weed management and re- vegetation issues. A copy of the Weed Management Plan is provided in Appendix Q. Air quality will not be affected nor will riparian areas, floodplains and wetlands. 5. Effects on Wildlife and Wildlife Habitat Impacts beyond those which would be common in an urban residential neighborhood are not anticipated. The subdivision will not have any adverse effect on fisheries. There are no natural watercourses on site. Public access to public lands will not be affected by this subdivision. There are no public lands adjacent to the subject property. The subject property is located within the corporate limits of the City of Bozeman in an area that has been deemed appropriate for future urban growth. The subject property is located within the corporate limits of the City of Bozeman in an area that has been deemed appropriate for future urban growth. The Montana Department of Fish Wildlife and Parks was notified of this subdivision, a copy of the correspondence is provided in Appendix J. WEST WINDS SW SUBDIVISION PRELIMINARY PLAT APPLICATION 18 6. Effects on Public Health and Safety The subdivision site is located in an area that is not particularly susceptible to natural hazards. The subject property is not located within the 100-year floodplain and is not at any higher risk of hazards caused by seismic activity than other properties in the general area. d. Other adopted state and local ordinances including, but not limited to applicable zoning requirements This subdivision proposal meets the intent and standards of the underlying Zoning Designation of R-3. The uses and densities proposed as part of this subdivision are consistent with that zoning district.

Allied Engineering has responded to specific comments that you had requested, as listed below. Our responses are shown in italics. Section 2 – RECOMMENDED CONDITIONS OF APPROVAL Section 2, Item 2: Block 1, Lots 16 and 17 shall be merged to a single lot. Lot 16 and Lot 17 of Block 1 have been merged into a single lot. As a result of the lot merging, the lot lines and dimensions for Block 1, Lots 1-16, have been revised accordingly. Also note the engineering plans have been revised accordingly for the corresponding Preliminary Plat Map revisions. See revised Preliminary Plat Map, dated 02-13-2018. Section 2, Item 3: Alley A shall be shortened and provide snow storage on expanded common open space L1. Alley A was shortened to provide for snow storage on the expanded common open space L1. The lots have been moved north, and the open space area has been increased to 0.119 acres (~5,187 sq ft). The previous area of the open space lot was 0.049 acres (~2,134 sq ft). See revised Preliminary Plat Map, dated 02-13-2018. Section 2, Item 4: Area under the easement included in document number 2595711 shall be dedicated to the public with this plat as right of way. The area under the easement has been dedicated to the public as right-of-way, which is located in the newly constructed round-a-bout area. It should be noted the previous reference to document number 2595711, was provided by others. However, the actual easement document, as recently recorded by the City of Bozeman, is Document number 2605445. We have revised this document reference accordingly. See revised Preliminary Plat Map, dated 02-13-2018. Please also note the addition of the Temporary Construction Easement Note.

Fax: (406) 582-5770 Page 2 TEMPORARY CONSTRUCTION EASEMENT NOTE: Per Document number 2605446, a temporary construction easement encumbers the subject property. This temporary easement is proposed to be abandoned prior to final plat approval, therefore, this easement is not shown graphically. Section 3 – REQUIRED CODE CORRECTIONS Section 3, Item 4: No utility easements for power etc are shown on the interior lots. The note is acceptable but the locations need to be depicted on the plat In addition to the easement fronting all the public streets (West Oak Street, Windward Avenue, Breeze Lane, and Davis Lane), we have provided additional 10 ft wide utility easements as depicted on the revised Preliminary Plat Map. This includes easements fronting the west, south, and east side of Block 6, and the west, south, and east side of Block 5. We have also extended and connected a new 12 ft wide utility easement within the interior portion of the new round-a- bout. In summary, these easements have been provided as part of the coordination and planning between the underlying developer/applicant and the utility companies, and easements have been provided for consistency with the utility layout. As a result, we have removed the Easement Not from the old Preliminary Plat Map. EASEMENT NOTE: In addition to the easements shown, all lots are subject to the following Utility Easements: - 10‐ft wide front yard utility easement.    See revised Preliminary Plat Map, dated 02-13-2018. See also proposed utility layout, as provided by NorthWestern Energy, dated 01-15-2018. Section 3 – REQUIRED CODE CORRECTIONS Section 3, Code Corrections, Item 1.b: The applicant must provide blue street signs for each of the alleys prior to final plat approval, similar to private street signs, and name the alleys to provide signage for emergency services. Allied has provided notes and clarification on Sheet C2.15 regarding the requirement for blue street signs for the alleys. The COB has also provided mark-ups for the signage plan, via Sheet C2.15, which included removal of the alley street signs, thus, the plan sheet mark-ups are in conflict with this comment. We understand that the private road names will be required for 911 emergency purposes, therefore, we have maintained the street signs per the revised Sheet C2.15, dated 02-13-2018. The alley names are still pending final approval from the GIS Department. We have maintained the alley nomenclature on the plans (Alley A, Alley B, and Alley C), and have provided a table on Sheet C0.3, regarding the proposed street corresponding alley street name.

Fax: (406) 582-5770 Page 3 Section 3, Code Corrections, Item 3 (first bullet point): The applicant must adjust the lot configuration to indicate right-of-way dedication for the intersection of Davis Lane and Oak Street. Although an easement currently exists to accommodate the intersection, the proposed lot configuration is confusing to potential purchasers of the lots near the intersection. The applicant must dedicate the right-of-way for Davis Lane, Oak Street, and the intersection of Davis and Oak and show the corrected lot dimensions prior to preliminary plat approval. The area under the easement has been dedicated to the public as right-of-way, which is located in the newly constructed round-a-bout area at the corner of Davis Lane and Oak Street. As a result of the right-of-way dedication, per this plat, the corresponding adjoining lots have been adjusted accordingly. See revised Preliminary Plat Map, dated 02-13-2018. See also response to Section 2, Item 4 (above): Section 3, Code Corrections, Item 3 (second bullet point): The applicant must use City standard alley approaches for access from public streets to the alleys per City Standard Drawing 02529-7A except where the alley approaches have already been constructed on Breeze Lane. The applicant must demonstrate the correct approaches prior to approval of infrastructure plans and specifications. The COB Standard Drawing 02529-7A Alley Approach detail assumes an inverted alley intersecting a street. We have a crowned (Alley A, and Alley B) and super elevated (Alley C) the alleys for drainage reasons. Instead a hybrid of both a residential and non-residential (COB Standard Drawing 02529-11 & 02529-12) driveway approach was utilized in the design for the three non-existing alley intersections with Windward Avenue and New Holland. The standard detail used for the new alley approaches is shown as Detail 2 on Sheet C5.4. The main design element of these alley approaches is to maintain sidewalk grade of the main street intersecting with the alley. Drivers will have to turn up onto the alleys thus discouraging public traffic from entering them. Also, the sidewalk will be connected to a concrete apron that will extend to the main street. Creating a different look than traditional residential streets. Section 3, Code Corrections, Item 5 (dead-end alley configuration comment): The dead-end alley configuration at the end of Alley “A” will not be accepted as proposed. The proposed configuration will result in snow plowed directly into the shared use path at the intersection of Oak Street and Davis Lane. Additionally, BMC Section 38.23.070 states requirements for water main construction. The proposed dead-end alley unnecessarily creates a dead-end water main at the end of the alley. The applicant must adjust the dead-end alley to eliminate the snow storage issue and eliminate the dead-end water main. Lot 16 and Lot 17 of Block 1 have been merged into a single lot, and the lot lines and dimensions for Block 1, Lots 1-16, have been revised accordingly. Alley A was shortened to provide for additional snow storage on the expanded common open space L1. The lots have been moved north, and the open space area has been increased. The dead-end water main has been eliminated, and water services extend southwesterly from the water main, to service Lot 15 and Lot 16 of Block 1, with water curb stop in the standard location. Note the sewer main does extend south of the intersection of Alley A and Alley B, for service to Lot 15 and Lot 16 of Block 1, and also sewer service to Lot 1 of Block 2.

Fax: (406) 582-5770 Page 4 Section 3, Code Corrections, Item 6 (road signage comment): The applicant must adjust the Raod Signage Plan on Sheet C2.15 to meet the requirements. The applicant must adjust the signage plan per the attached City markups to the plan prior to approval of infrastructure plans. The applicant must also indicate no parking signs and panted curbs were no parking will be allowed. As required in Section 3, Code Corrections, Item 1.b, Allied has provided notes and clarification on Sheet C2.15 regarding the requirement for blue street signs for the alleys. The COB has also provided mark-ups for the signage plan, via Sheet C2.15, which included removal of the alley street signs, thus, the plan sheet mark-ups are in conflict with comment 1.b (above). We understand that the private road names will be required for 911 emergency purposes, therefore, we have maintained the street signs per the revised Sheet C2.15, dated 02-13-2018. The alley names are still pending final approval from the GIS Department. We have maintained the alley nomenclature on the plans (Alley A, Alley B, and Alley C), and have provided a table on Sheet C0.3, regarding the proposed street corresponding alley street name. As part of the COB redlines to Sheet C2.15, there were some suggested removal of stop signs onto several City Streets. Stop signs from the Alleys were maintained for the approaches to Breeze Lane, but were suggested to be removed for the alley approaches to Windard Avenue, and New Holland Drive. We have removed the stop signs internal to the Alleys, but suggest keeping the stop signs access all city streets (ie. Breeze Lane, Windward Avenue, and New Holland Drive). No parking signs and painted curbs have been denoted, with reference to individual detail sheets that are not so cluttered. In summary, we have incorporated the suggested revisions to the signage plan, along with some of the above reference conflicts, in hopes that the signage plan is adequate for your approval. Section 3, Code Corrections, Item 7 (sidewalk comment): The applicant must locate the sidewalks proposed in the alleys 1-foot off the property line. The applicant must indicate the corrected sidewalk locations on all drawings prior to final plat approval. To accommodate the requirement for sidewalks being 1 ft off property line, all alley right-of-ways have been widened from 44 ft wide, to 45 ft wide. The alley right-of way was widened only on the side of the proposed sidewalk, allowing for the 1 ft separation. For Alley A, the alley right-of- way was widened 1 ft east. For Alley B, the alley right-of-way was widened 1 ft west. For Alley C, the alley right-of way was widened 1 ft north. This modification allowed for maintaining the same road, water, and sewer alignments, and corresponding intersection grading. The Preliminary Plat Drawing has also been adjusted per the 45 ft wide alley right-of-way. This resulted in slightly smaller lots on Block 5 and Block 6. The affected water and sewer services were extended an additional 1 ft, such that they extend into the revised lots, consistent with the original plans. The corresponding water and sewer service tables have also been adjusted accordingly, as well as the right-of-way section details. See revised Preliminary Plat Map, dated 02-13-2018.

Phone: (406) 582-0221 . Fax: (406) 582-5770 Page 5 Section 3, Code Corrections, Item 8 (first bullet-point): Where existing water main and sanitary sewer main stubs will not be used, abandon the stubs per City Water and Sewer Division requirements. The applicant must demonstrate proper abandonment prior to approval of infrastructure plans and specifications. We have added notes on Sheet C0.4 for proper abandonment of existing water main and sanitary sewer mains that will not be used. See revised Plans, dated 02-13-2018. Section 3, Code Corrections, Item 8 (second bullet-point): The profile view of the water main on Sheet C4.3 indicates “C900” pipe. The applicant must replace this note with ductile iron CL 51 water main pipe to meet City standards and to be consistent with other notes on the drawings that are correct. The reference to “C-900” pipe on Sheet C4.3has been removed, and corrected with Class 51 DI Water Main, consistent with the entire plan set. See revised Plans, dated 02-13-2018. Section 3, Code Corrections, Item 8 (third bullet-point): Drawing C4.4 indicates a high point in the water main in Alley “C”. The applicant must adjust the design to allow air to release from the system. The high point at the gate valve in Alley C (Sta: 12+48) was lowered to be level with the Tee (Sta: 12+47) in New Holland and eliminated the local high point in the water main. See revised Plans, dated 02-13-2018 Section 3, Code Corrections, Item 8 (fourth bullet-point): The pipe insulation Detail 1/C5.4 describes use of insulation as “alternate.” Insulation will only be allowed where it is not feasible to meet the cover requirements (6.5-feet cover for water mains and 5-feet cover for sanitary sewer mains). Use of insulation was not intended as alternate, nor to encourage insulation use, but the way the insulation is installed can be done two different ways. To clarify the insulation detail on Sheet C5.4, it has been changed to say TYPICAL CONFIGURATION and NARROW TRENCH CONFIGURATION for use of insulation, if required. Section 3, Code Corrections, Item 10 (stormwater comments): The applicant must provide an analysis of the subdivision stormwater detention volume. A flow rate analysis was provided, but the applicant must also review the original subdivision detention volume analysis and demonstrate sufficient volume exists in the existing detention system to accommodate the proposed project. Refer to the new Storm Drainage Design Report for Phase 2 (dated 02-13-2018) that specifically addresses drainage for the Phase 2 subdivision. No additional inlets or piping is proposed for storm conveyance for Phase 2. Run-off will surface drain to existing inlets in Breeze Lane and ultimately to the master detention ponds for the overall West Winds PUD. The peak flow and volume from West Winds SW is equal to or less than the original design flow as set in the original design by Dowl HKM. This is justified in that the weighted run-off coefficient for West Winds SW is less than the what was used in the original design. To clarify a lower run-off coefficient means less excess rainfall (storm run-off) as more is infiltrated or retained in these areas.

Fax: (406) 582-5770 Page 6 Conditions of Approval, Item 3: The applicant must revise the groundwater note on the preliminary plat to indicate that no crawl spaces or basements will be allowed due to high groundwater conditions at the site. The dates of the groundwater measurements in the preliminary plat application indicate the applicant did not capture the seasonal high groundwater level (SHGWL), and the measurements were taken on a low water year. The City has aerial imagery indicating groundwater at the surface of the site. There is insufficient depth to the SHGWL to allow crawl spaces or basements. Allied agrees that basements should not be allowed for this development. However, we feel that crawl spaces should be allowed, with limitations on foundation depth. We are confident in the groundwater note that was originally stated on the preliminary plat. This note is the same groundwater note that was provided for the previous condo development on the north side of Breeze Lane, which called for 3.0 ft below existing grade, and the south side of Breeze Lane called for 4.0 ft below existing grade. To accommodate for concerns from the City of Bozeman, we have since revised the text on the preliminary plat to represent just the south half of the overall property, which is specific to this project, and we reduced the foundation depth to a maximum of 3 ft (in lieu of 4 ft). This depth would match the same conditions as the north half (condo lot). Please also note that the crawl space will be required to be filled in to the top of the footer, which is typically about 8 inch thickness. This would result in the crawl space finished grade less than 2.5 feet from ground surface. Please find attached our Groundwater Memo (dated 02-12-2018) and Groundwater Contour Map, in support of the proposed maximum foundation depths. See below regarding the groundwater note that was included on the revised preliminary plat map. GROUNDWATER NOTE: The proposed development lies in a known high groundwater area. To minimize the chances for high groundwater to enter the crawl space, the depth of the crawl space should be limited to about 3.0 feet below existing grade. As an added precaution, the floor of the crawl space should be infilled with clean crushed rock up to the top of footings to further raise the bottom of the crawl space to shallower depths. See the geotechnical report for 2016 groundwater monitoring data and some additional moisture protection recommendations for crawl spaces. According to current City of Bozeman policy, no crawl spaces or basements may be constructed such that sump pumps are required to pump water from these spaces. Sump pumps are not allowed to be connected to the sanitary sewer system. Sump pumps are also not allowed to be connected to the drainage system unless capacity is designed into the drainage system to accept the pumped water. Water from sump pumps shall not be discharged onto streets, such as into the curb and gutters where they may create a safety hazard for pedestrians and vehicles.                                                                                                                                                                                              Page:  __1__  of  __1__    MEMO 32 Discovery Drive                Bozeman, MT  59718                (406) 582‐0221                 Fax (406) 582‐5770  Project Name: West Winds SW –Phase 2 Project Number: 16-003 Date and Time: February 12, 2018 Re: Groundwater Conditions To: City of Bozeman From: Mark Fasting, PE - Allied Engineering Services, Inc. MEMO DETAILS: Groundwater monitoring was performed in the spring of 2016 in order to develop a groundwater surface. Monitor wells were installed February 2, 2016 and depths were recorded roughly every 2 weeks starting March and continuing through May. The peak groundwater elevations for all 8 monitoring wells were observed on April 8. A groundwater surface based on the highest observed groundwater elevations was generated and can be seen with finished grading on attached Exhibit 1. It should be noted that monitoring was ended in May due to the start of construction and construction dewatering; as a result a groundwater peak outside the duration of monitoring would not have been observed. Also, monitoring performed in 2016 may not represent the highest typical groundwater condition when compared to other years. A finished grade surface has been developed for the entire site to ensure drainage is provided from the lots to adjacent roads. In general, the depth to groundwater compared to the finished grade surface ranges from 6 to 8 feet within the lots. The top of foundation wall for the proposed structures will be at least 0.5 feet to 1.0 foot above the adjacent finished grade to maintain positive drainage away from the structure. Crawl spaces are anticipated to be 4 to 5 feet below top of foundation wall. Based on the assumptions above, groundwater is expected to be a minimum of 2-ft below crawl spaces during seasonally high groundwater.

Fax: (406) 582-5770 Page 2 1 Introduction and Overview The following report addresses storm water management for the West Winds SW – Subdivision (Phase 2). The West Winds SW project consists of two phases: Phase 1 an existing Condo Development, and Phase 2 a proposed subdivision. This project area is part of the larger West Winds Planned Unit Development (PUD). Design for the West Winds PUD was completed in a total of eight phases with this proposed project falling within phases 4 and 5. Each phase was designed by Dowl HKM. The original PUD storm water run- off design done by Dowl HKM planned for development in this area of similar density. This report will reference the City of Bozeman (COB) approved storm drainage reports from Dowl HKM and Allied Engineering, Inc. The most significant and up-to-date report for the PUD is the West Winds Planned Unit Development: Stormwater Investigation Phase 6 Subdivision by Dowl HKM. The storm drainage report by Allied Engineering for the project (West Winds SW Storm Drainage Report, West Winds Southwest) covered both Phase 1 and 2 but only Phase 1 has been constructed. The original storm water infrastructure outlined in this report has not changed for Phase 2. The purpose of this report is to demonstrate that the proposed conditions for Phase 2 produce the same or less run-off than the original design by Dowl HKM. Specifically, that the rational coefficients used for West Winds SW design are the same or lower than the original Phase 4 and 5 of the PUD. 2 Description of Site/Background Data The overall West Winds SW site is bounded by Davis Lane to the west, West Oak to the south, Windward Avenue to the east, and Winter Park Street to the north. The existing Phase 1 consists of Condos from Breeze Lane to Winter Park Street. South of Breeze lane to Oak Street is Phase 2. Phase 2 will consist of 73 residential lots. Run-off from Phase 2 will utilize the existing storm water inlets from Phase 1 to convey run-off into the off-site storm infrastructure. Design the underground conveyance was completed with the Phase 1 submittal and approved by the COB. The existing underground conveyance from West Winds SW to the larger PUD flow to the existing East and West Master Ponds. These master ponds are hydraulically connected and serve the entire west portion of the West Winds PUD. These master ponds have a design storage volume of 68,657-cu.ft. and overall storage volume of 140,813-cu.ft. The required storage for this pond is 67,494-cu.ft. for the 10-yr storm event based on the 2013 Phase 6 report. This required storage was calculated using the rational coefficients for the contributing area to the ponds shown in Table 1.

Refer to Figure 3 from the Phase 6 Report for views of the master ponds and drainage structures to reach them. As can be seen from these figures the previous areas are similar enough to our project boundaries to be used to justify hydraulic sizing and design. 3 West Winds SW - Phase 1 & 2 The delineated drainage basins of the West Winds SW project are shown Appendix A. For individual and overall weighted rational coefficients C refer to Table 2. The total area of the project is 18 acres which is slightly less than the total area of Phase 4 and 5 of the PUD’s original design. This is because only the area of West Winds SW was delineated unlike the original design which covers all area within the PUD. The area for development within West Winds SW was assumed to be Commercial/Retirement/Assisted Living areas with a higher C value of 0.6. These dense developments are similar to both the existing high-density condos and proposed subdivision. The weighted C for the overall Phase 4 and 5 area is 0.62. The overall weighted run-off coefficient for the proposed West Winds SW project is approximated 0.59. This lower C value comes from having more open space in the subdivision area. Given the simple nature of the Rational Method the proposed development will produce less run-off volume and a lower peak flow. The rational method is simply the run-off coefficient times the rainfall intensity times the area. Both area and rainfall intensity are held constant while substituting the lower C value will produce lower run-off. It would be conservative to utilize the existing underground conveyance, structures, and detention ponds to treat storm water run-off from both Phase 1 and 2 of West Winds SW without any design changes.

In general, infrastructure located within the right-of-way or public utility easement will be maintained by the City, the remaining infrastructure will be maintained by the HOA. Inlet and junction structures will have a minimum sump depth of 9-inches. The sumps will collect large debris requiring removal. Inlets are located within public right-of-ways and public utility easements and will be maintained by the COB. 5 Conclusion/Summary of Results West Winds Southwest is located within the original West Winds Development PUD. The engineering was completed by HKM and design reports provided for each phase of development (on file at the City of Bozeman Engineering Department). The project site is specifically located within portions of phase 4 and 5 of the original development and was included with planning and design of conveyance and storage infrastructure for the overall development. Existing storm mains were connected in Phase 1 to convey drainage to the existing detention ponds for the PUD. These ponds Master West and Master East located Haystack Development February 13, 2018 Project: 16-003 Bozeman Office . 32 Discovery Drive . Bozeman, Montana 59718 . Ph: (406) 582-0221 .

The conveyance infrastructure for both the West Winds SW and overall PUD are both designed to handle the 25-yr event as shown in the previously mentioned reports. In conclusion the design events for the West Winds SW project will produce smaller peak flow and less run-off volume than originally designed due to a lower run-off coefficient of 0.59 compared to the original Phase 4 and 5 value of 0.61.
