Temporary culverts were installed under Permit GD-02-03 at Sherwood Way (Impact 42 Exhibit) authorized for Chuck Hinesley of Laurel Glen Subdivision and under Permit GD-052-05 at Oak Street(Impact#4 Exhibit) for John Rosa of Rosa Subdivision. 5. WHAT IS THE PURPOSE of the proposed project? Construction of Phases 1 and 2 of Laurel Glen Subdivision was started in 2002. Phases 3 and 4 of the subdivision encompassing Baxter Creek and an unnamed tributary of Baxter Creek (aka Baxter Ditch) were never developed. Hinesley Development submitted a preliminary plat application to the City of Bozeman for the final development phases.in December 2008. The project was sold to Four Corners Construction, LLC in 2013. Permit GD-81-02 was approved on January 17, 2003, for three 54-inch by 88-inch reinforced concrete pipe (RCP) culverts to be installed across Baxter Creek as part of the subdivision road development. The permanent culverts were never installed. This 310 permit application is for the installation of four arched concrete culverts, three on Baxter Creek and one on the UT of Baxter Creek to provide road access for Westbrook and Boulder Creek Subdivisions both owned by Four Corners Construction. The culvert impacts and specs. are shown on the enclosed Wetland Impact Summary sheets for Westbrook and Boulder Creek Subdivisions and on the Exhibits for Impacts #1 to #4. Impact #5 is associated with filling in the gravel pit lake, which is not within the Conservation District's purview. The US Army Corps has been contacted. PROVIDE A BRIEF DESCRIPTION of the proposed project. nree arched reinforced concrete (RCP) culverts pleasuring 54 inches by 88 inches will be installed in Baxter Creek for the Annie Street, Sherwood Way, and West Oak Street crossings. The culvert lengths are listed on Exhibits for Impacts#1, #2, and #3. A 36 inch by 58 inch RCP culvert will be placed in the UT of BC for the West Oak Street crossing. Exhibit #4 provides the details. The impact locations are summarized on the Wetlands Impact Summary sheets for Westbrook and Boulder Creek Subdivisions. There are existing temporary culverts at the Sherwood Way/Baxter Creek and West Oak/UT of BC crossings that will have to be removed to install the permanent concrete culverts. '7-: WHAT IS THE CURRENT CONDITION of the proposed project site? Describe the existing bank condition, .nk slope,height, nearby structures, and wetlands. The banks have been impacted at the temporary crossings on Sherwood Way and West Oak Street. Baxter Creek has a dirt road crossing without a culvert at West Oak Street. Construction fence was placed at the crossing to prevent vehicles from driving through the stream. The banks at Annie Street are relatively unimpacted and well-vegetated with beaked sedge, Nebraska sedge, and meadow foxtail. The banks range in height from 1 to 2 feet. Baxter Creels has 50-foot watercourse setbacks from the stream. 8. PROJECT DIMENSIONS. How many linear feet of bank will be impacted? How far will the proposed project encroach into and extend away fiom the water body? See Impact Exhibits#1 to#4: Impact 41 —Annie Street: 141 feet of Baxter Creek Impact#2 Sherwood Way: 90 feet of Baxter Creek Impact#3 West Oak Street: 84 feet of Baxter Creek Impact#4 West Oak Street: 84 feet of the UT of Baxter Creek(Baxter Ditch) 9. VEGETATION. Describe the vegetation present on site. How much vegetation will be disturbed or covered with fill material during project installation? (Agencies require that only vegetation necessary to do the work be removed.) Describe the revegetation plan for all disturbed areas of the project site in detail. —ie upland benches are dominated by meadow foxtail (Alopecurus pratensis). Secondary upland species elude smooth brome (Bromus inermis), Kentucky bluegrass (Poa pratensis),musk thistle (Carduus nutans), common dandelion(Taraxacum officinale), and wild mustard (Brassica kaber). The wetland vegetation is dominated by meadow foxtail, beaked sedge (Carex utriculata—OBL), and Nebraska sedge (Carex nebrascensis—OBL). Isolated clusters of Bebb willow(Salix bebbiana—FACW) and thin-leaf alder(Alnus tenuifolia—FACW) line the streambanks of Baxter Creek near the Annie Street crossing. Areas disturbed by the culvert installations will be reseeded with a streambank mix composed of streambank wheatgrass, slender wheatgrass,tufted hairgrass, and fowl bluegrass. 10.MATERIALS. Describe the materials to be used and how much. Cubic yards/Linear feet Size and Type Source See Impact Exhibits 91 to 4. 11. EQUIPMENT. What equipment is proposed to be used for the work? Where and how will the equipment be used on the stream bank and/or the waterbody? The equipment will work outside the top of the streambank. A trackhoe, grader, dump truck, and front-end loader will be used for the culvert installations. 12. DESCRIBE PLANNED EFFORTS TO MINIMIZE PROJECT IMPACTS. Consider the impacts of the -)posed project, even if temporary. What efforts will be taken to: ® Minimize erosion, sedimentation, or turbidity? The culverts will be installed during low flows in late summer. Silt fence will be placed parallel to the stream to prevent sediment from entering the stream. The streambanks will be revegetated with seed as soon as possible after construction. The streamflow will be contained behind a coffer dam and piped to the downgradient reach during construction. ® Minimize stream channel alterations? The Bozeman street grid dictated the ROW for the roads. Alterations to the stream channel were minimized to the extent possible. The culvert inlets and outlets will be flared ends. Rock will be used at the edge of the flared ends to prevent erosion. ® Minimize effects to stream flow or water quality caused by materials used or removal of ground cover? The culverts were designed for the 100-year flow event. Impacts to water quality will be short-term and occur only during the culvert preparation and installation. Disturbed areas will be revegetated as soon as possible following construction. Silt fence will be used to prevent sediment from discharging to the stream. Construction will take place during low flows. ® Minimize effects on fish and aquatic habitat? The streamflow will be contained behind a coffer dam and piped to the downgradient reach during construction to minimize impacts to fish. Construction will take place in late summer during low flows. ® Minimize risks of flooding or erosion problems upstream and downstream? The culverts were designed for the 100-year flow event. There is no increased risk of flooding as a result of the culvert installations. Silt fence will be used to prevent the introduction of sediment to the stream. Disturbed areas will be revegetated with seed as soon as possible following construction. ® Minimize vegetation disturbance,protect existing vegetation, and control weeds? The extent of the construction area will be minimized to the extent possible. The removal of large trees or shrubs will be avoided if possible. Disturbed areas will be reseeded as soon as possible to minimize the introduction of weeds. 13. WHAT ARE THE NATURAL RESOURCE BEN.EFITS of the proposed project? The installation of culverts will prevent vehicles fiom crossing through the streams.. The length of the culverts, except for the Annie Street crossing,will still allow fish access upstream. The culverts will facilitate the street grid system proposed in the Bozeman City master plan. The stream crossing at Glenwood Street was removed to reduce impacts to Baxter Creels. 14. LIST ALTERNATIVES to the proposed project. Why was the proposed alternative selected? The installation of four bridges would be prohibitively expensive particularly on small streams like Baxter Creek and the UT of Baxter Creek. The culverts and roads will prevent vehicles from driving through the creeks and destroying the stream banks. One culvert crossing on Baxter Creek proposed originally at Glenwood Street(now Ethan Way) was removed in the current plat layout for Westbrook Subdivision.

The expiration date for the permit amendment is June 8, 2014. The undeveloped land within the subdivision was sold by Charles Hinesley in 2013 to Four Corners Construction, LLC, represented by John Rosa. A signed Transfer of Ownership form was sent to John Short with the US Army Corps Helena office on.June 3, 2013. The land will be divided into two new subdivisions called Westbrook and Boulder Creek Subdivisions as shown on the respective Wetlands Impact Summary exhibits enclosed with this submittal. The original delineation for the Laurel Glen Subdivision located in Bozeman, Montana, was completed in November 2001. US Army Corps of Engineers (USACE)Permit 2001-90-847 was approved on October 15, 2002., and expired on October 15, 2007. Phases 1 through 4 (Phases 3 and 4 were never developed) of the subdivision encompassed 157 acres located in the East 'h of the SW I/4 and the West 1/2 of the. Southeast 1/4 of Section 4, Township 2 South and Range 5 East,Gallatin County. This letter is a request to authorize Amendment'5 associated with this permit to address changes .in the subdivision ownership and plat layout. The 2013 wetland impact areas for the culvert installations are summarized in Table 1.0. The culvert sizes and road specifications and fill volumes have not changed from 2009 to 2013. Table 1.0. Culvert installation impact summary for 2613 plat layout.

The 2013 plat layout has eliminated the crossing on Baxter Creek at.Glenwood Drive. The extent of proposed impacts to jurisdictional waters of the US totals 0.46 acres for culvert installations associated with road development in Westbrook and Boulder Creek Subdivisions. Wetland impact#5 listed and shown on the Boulder Creek Subdivision Wetlands Impact Summary is associated with filling in a portion of a gravel pit lake that has developed since project construction began in 2002. The gravel pit was originally going to be backfilled. The new owners would like to develop the pond as an amenity. The gravel pit lake was assumed to be jurisdictional based on the proximity to Baxter Creek(within 10 feet in some areas),the presence of a rocky soil substrate, and the establishment of wetland vegetation around the perimeter of the lake. The gravel pit pond encompasses 49,057 square feet (1.13 acres) of open water with a three-foot wide wetland fringe (3851 sf, 0.09 acres) on the pond perimeter. Approximately 12,428 sf(0.29 acres) of the pond will be filled for lot development. The remaining pond will provide 0.84 additional acres of a lacustrine system and 0.09 acres of lacustrine fringe. The total impacts to project wetlands from the culvert installations and pond fill are 0.75 acres (0.46 plus 0.29 acres). Amendment 4 references a total of 2.89 acres for full buildout of the project, 2.11 acres from impacts that occurred before 2008 and 0.78 acres from the culvert installation impacts addressed in Amendment 4. The impact acreage requested for Amendment 5, 0.75 acres, is slightly less than the 0.78 acres referenced in Amendment 4. Infrastructure construction is anticipated in fall.2013 and 2014 dependent on preliminary plat approval,USACE permit approval, and the economy.

US A,nny Corps of Engineers (USACE)Permit 2001-90-847 was approved on October 1.5,2002, and expired on October 15, 2001. Phases 1 through'4 of the subd.ivisioii encompass 1.57 acres :located in the East% of the SW V4 and the'Vilest '/Z of the Southeast'/a of Section 4, Tovmship,2 South-and.Range 5 East, Gallatin County (Figure 1). Durston Road parallels the south property boundary. The east property boundary lies 0.25 miles west,of Cottonwood Road and the west property boundary lies 0.25 miles east of.Gooch Hill Road. Phases 3 and 4 of the subdivision encompassing Baxter Creek and Baxter Ditch were never developed.(Wetlands Impact Summary, Laurel Glen Subdivision, Phases 3 and-4, Sheet 1 of 6). Hinesley Development is submitting a preliminary plat application to the City of Bozeman for the final development phases in December 2008. .Over fire years have elapsed isincethe initial-delineation. The wetland boundaries associated with Baxter Creek and Baxter Ditch were re-delineated on June 24,,2008. Annual field investigations conducted after 2001 indicated that the boundaries of the broad fiverine fringe:associated with Baxter Creek had decreased,as a result of the change in land use from flood irrigated pasture to residential. This was eoaifirmed by the 2.008 4olineatiou results(Sheet 1). 1.2 MITIGATION GOALS.AND OBJECTI`TES Impact Sites Three perennial waterways traverse the, property; Baxter Creek, Baxter Ditch., a»d an unnamed tributary to Aajker Creek. Baxter Creek origipates from the Farmer's Canal south of US 191 and traverses the east half of the project site from the south to north property.boundaries. Baxter Ditch, also known a&an unnamed tributay to Baxter Creek; was originally diverted from the Maynard-Border Ditch located south of the project. The segment of Baxter Ditch from West Babcock Road to Durston Road was-relocated to The west side of Cotton-wood Road in 1998 as part of mitigation project for an adjacent development_ Once it-crosses Durston.Road,the ditch flows north through the adjacent landowner's property until it enters :and exits. through the northeast corner of Laurel 01en. The ,confluence of Baxter Ditch and Baxter Creek is approximately 1.5 miles no!-.th of the project site. .An unnamed tributary to Aajker Creek flows. through the southwest corner of the property, joining Aajker Creek. midway .along, the west boundary. Impacts to the tributary.of Aajker Creek were•addressed ill the 2002 404 permit. Development of Phases 3 anal 4 will require the installation of four culverts across Bader Creek and one culvert across Baxter Ditch. These culvert crossings were included on the original permit. There is -an existing temporary culvert at the Sherwood Way crossing,that will be replaced with a perihanent concrete culvert. The total impact from the installation of the culverts is 0.87 acres (Sheet 1 of 6 — -Wetland lmpaet Summary). Construction details at -each street crossing are included on Sheets 2 through.6. Mifigation Sites Laurel Glen. Subdivision lies within.the growth corridor defined in the 200.1 Bozeman Master Plan. The historical land use was agricultural, primarily crop production and Iivestotk pasture. One of the long-range goals of the project was to restore water quality azrd fish habitat conditions in the unnamed tributary of Aajker Creek.and Baxter Creek. Mitigation for the bl ti'ion Play.-Laicrel�lYvi SKE9G�i1/i$LOYt original permit included -reestablishing 185-0 feet 'of-the .Aaiker Creek tributary, which was completed.in gurumer and fall 2005. The restoration encompassed reconstruction of the floodway 'and.base flow channels and construction of pools,riffles, and meanders. Tbo stream uorridorwas further enhanced with the installation ofnative.1rees and:shrubs, The reach of Baxter Creek north of Durston Road historically encompassed are on-stream reservoir. The weir was removed in 2002 allowing the channel to reestablish itself. The darn and culvert were removed in 2007 and the impacted channel reach restored.. Mitigation for the original permit also included the creation of a '0.9 acre wetland complex .north of Durston Road and a 0.86 acre floodplain wetland southeast of-Annie Street(Sheet 1 of 6). The.mitigation wetlands were constructed and seeded in fall 2007. The south wetland complex was built with,several shallow water pools vegetated with wetland sod mats and oustom native seed mixes: The north wetland was seeded with the custom seed mixes. Fifty Bebb, .Pacific, and peach-leaf containerized willows were planted on the outside curve of Baxter Creek adjacent to the.north mitigation wetland in August,2008. The following information was outlined in an email sent to Jean Ramer,the Army Corps agent for this project, from Barbara Vaughn on November 15,2007. The original permit allowed for 4.08 acres of impact. The extent of impacts completed at the time of the permit expiration was 2.24 acres. The total mitigation credits accrued at the time of the permit expiration was 3.05 acres leaving a mitigation credit of 0.81 acres. The mitigation credit assumes a 1:1 ratio for creation of a viable wetland (floodplain wetlands on Baxter Creek) completed prior to the subdivision construction activities. Jean Ramer was contacted via email on October 17, 2008,to ascertain whether the excess mitigation.credit could be applied to the niew-Permit. She stated that the mitigation credit could be applied to-the new. 404 permit provided that the mitigation wetlands Meet the required success criteria within the three year monitoring period. The remaihing wetland.impacts for the new 404 permit totaling 0.06 acres (0.87 less 0.81) would b.e.rnitigated. for by enhancing the Baxter. Creek and Baxter Ditch corridors with the installation of containerized.native trees and shrubs. Enhancement of 5,4:acres of wetlands associated with the Baxter Creek corridor at a 4:1 ratio would yield 1.35 acres of credit. Enhancement of 0.17 acres of the Baxter Ditch w-etland corridor will provide 0.043:acres of credit at a 4:1 ratio. The City of Bozeman requires a 50-foot setback from the edge of perennial streams and the associated wetland fringe, which will create a water quality buffer. A publictrail constructed with sand and clay will be built within the outer 20 feet of the 50 foot watercourse setback. 1,3 BASELINE 31'ORKATION _Quantity Wetland Resources .The extent of-the Baxter Creek riverine wetlands decreased after 2002 as shown on Sheet l of 6. In 2001, the Baxter Creek riparian corridor encompassed approximately 7.8 acres. In 2008 the riverine wetlands extend, across 5.4 acres, a reduction of:2.4 .acres. The Baxter Ditch channel and riverine al rivfringe encompass 0.17 acres. Baxter Creek and Baxter Dittrh are classified as lower erennierine wetlands with rack bottoms under the Smith Hydrogeonmrphic System.(Smith et 61. 1995).. -The riverine fringe is dominated by emergent vegetation (Cowardin et at. 1979): The watier regime .is permanently. flooded. Baxter Creek flows north, ultimately :discharging to the East Gallatin River approximately 10.5 miles north of the project site. Riverine wetlands occur-in fl.00dplains and riparian corridors in association with stream channels (Hansen.'et al.. 1-995). Water usually,but not always,flows in riverine systems. 'Dominantwater sources are overbank flow. from the channel or subsurface hydraulic connections between the stream channel and wetlands.. " The functional. assessments were completed in 2001 as part of the original delineation.. The Baxter Creek corridor scored highest in functional value of the wetlands on file project site. Mitigation.PIRN - Laurel Ctlew S[•C'LGtC✓GSLGln 3 It was rated-.as a Category III wetland with 5.2.4 percent of the total possible functional ppints. Baxter Creek scored high.for general wildlife habitat, production export and food chain support, and groundwater recharge and discharge._ The ratings were -moderate fair sediment, nutrient, toxicant removal, and sediment and shoreline stabilization. The creek scored low for general lisli and aquatic habitat as a result of the on-stream reservoir. Baxter Ditch was rated as Categoiy1V wetland with 26 percent of the total functional points.. The creek was rated moderate for general wildlife habitat and sediment, nutrient,.and toxicant.removal. The remaining functional ratings were low. Existing Hvdvolog The subdivision site is located on the Bozeman alluvial fan conriplex; an exteitsive Quatemary-aged geologic formation covering nriuch of the southwest corner of the Gallatin Valley. The property is relatively level (1.0 to 1:.59K) ranging in elevation from approxiinately 4,760 feet above mean sea level (ams])-at the south boundary to 4,740 feet amsl at the north boundary (USGS 1957), There are no potential geologic hazards present with respect to slope stability, mass movement, surface subsidence;. or soils bearing capacity... Three perennial. waterways traverse the property; Baxter-Creek, Baxter Ditch, and the tributary to Aajker Creak. An extensive system of waterways originates in the :Gallatin 'Valley, .1low.ing in a northerly direction to the East Gallatin River. The three perennial streams are tributaries of the East Gallatin.River and,therefore,are considered"Waters of the US". This area of the Gallatin Valley exhibits a relatively shallow groundwater table. Groundwater depths typically range front one to six feet below the ground surface; Groundwater depths measured in monitoring wells .located on the south side ,of Durston Road fluctuated : between.0.25 and 2.5 feet.in 200'l. Seasonal high groundwater rises witliio two.to three feet of the ground surface across much.ofthe site. existing Veaetation The upland bench west of Baxter Creels between Glenwood Drive.and Annie Street was dominated .in 2008. by meadow. foxtail (Alopecurus praterasis —'FA.CW). A shift in plant. dominance had occurred since the•2Q0'1 ,delineation resulting in less Baltic-rush(Jwt cus baltiGvs— OBL) and Nebraska sedge (Carox ncbrascensis — OBJ,). Secondary upland species included smooth brume. (Brornus inermis — NL), Kentucky bluegrass (Poa pratensis — FACU+), musk thistle (Car-Aus nutans — NL), .common. dandelion (Taraxacum affrcinale — NL), and wild. mustard.(&rassica kaberr--NL). Vegetation within the A-verine fringe was dominated by meadow.foxtail, beaked sedge (Carer utriculata—.OBL),and Nebraska sedge. Isolated cWters of$ebb willow(S-alix bcbbiana — FACW) and thin-leaf alder (fJ:lnus tenuifolia —7:ACW).lined the streambanks. The wetrand vegetation associated with Baxter Ditch was primarily confined to the channel edges.and small, shallow adjacent basins, SpMes along the channel included meadow foxtail, Kentucky bluegrass, and beaked sedge. In inundated areas, beaked sedge-and Nebraska sedge dominated the cover. Upland vegetation included smooth brome, Canada thistle (Qrsium ar ense -- FACU+)and•quackgrass(Agropyron repens,FACU) Ei xisting Soils The Gallatin County Soil Survey-classifies the project laudforms-as stream terraces.and alluvial fans.formed on loamy•alluvium parent material. Tho area receives approximately 15 to 19 inches of precipitation per year based-on the soil survey data. There are:eight.mapped NRCS soil types within the property boundaries. Soil.adjacent to Baxter Creek was identified as poorly Ml&jatian Flan- tdurei.4leri skbdi v!,,49r. � drained Lamoose silt loam (537A), hydric soil classified as Typiic Endoaquo.Ils. The remaining soil types located'in upland areas included the Hyalite-Beaverton Complex(448A), Turner loam (57B),or Amsterdam.-Quagle silt loam.(453B). These soils,are characterized as non-hydric,viell- drained silt loams found on alluvial fans,. stream terraces, and relict stream terraces. Soil near Baxter Ditch was mapped as the well-drained Hyalite-Beaverton Complex, non-hydric soils. classified as Typic Argiustalls. Other snap units identified onsite include the Fairway silt loam (51 IA.),.Enbar loam(509B),and Meadowcreek loam(510B). The geotechnical report concluded that the site is covered'by 0.5 to 1.0 feet of topsoil and vegetation. The underlying soils consist.of a. layer of lean clay-and sandy lean,clay ranging in depth from 1.5 to 3.0 feet below the existing site grades. The fine-.grained soils.are moderately compressible, have a low potential to swell, have.a-medium plasticity and are soft to medium stiff. Gravel with sand and.cobbles was encountered beneath the clay layer up to 14.5 feet below existing site grades. Existing Wildlife Wildlife use based on the observation of scattered wildlife gropps and the common occurrence of wildlife signs consisted-of white-tailed and mule deer,short-tail weasel,voles,fiold mice, common tern, sandhill cranes,blue heron,hawk species(Buteo spp and Accipiter spp.),and falcon species(Falco spp). Historic and Current Land Use Historic land uses include agricultural production(grass hay) and livestock grazing. The surrounding area encompasses relatively flat terrain characterized by irrigated cropland. The subdivision lies on.the west edge of'Bozeman.within the area slated for development by the 2001 City Master Plan. Watershed Context/Surrounding Land Use The south boundary of the project parallels Durston Road. Valley West Subdivision is located south of Durston. Flanders Creek.and Rosa Subdivisions are located east of Laurel Glen. The land,west and, north of the-project is relatively undeveloped, used for crop production and livestock pasture: Baxter Creek, Baader Ditch and the Aajker Creek Tributary are Iocated within the project.boundaries. All three stream systems are classified -as perennial drainages that ultimately discharge to the East Gallatin River north.of Belgrade,Montana. 1.4 MITIGATION SITE SELECTION A•LV1U JUSTIFICATION The permit is conditioned to require compensatory mitigation to.offset wetland impacts. Wetland itripaets were avoided and minimized to the extent possible. Impacts to wetlands -occurring :onsite• associated with the development of the Laurel Glen :Subdivision will be mitigated within the boundaries-of-the proposed subdivision. The extent of proposed impacts to jurisdictional waters of the US totals 0,87.acres for development of Pbases 3.arid 4: Infrastructure construction is anticipated in 2009-or 2010 dependent on the preliminary plat approval, USACE permit approval, and the economy. Mitigation details including the ratios used to calculate mitigation requirements are listed in Table 1.0. Enhancement of.5.4-acres ofthe Baxter Creek corridor and 0.17 acres of the Baxter pitch corridor will entail planting.clusters of containerized native#fees and shrubs along both sides of the,channel. Development of:a woody overstory is expected to increase the structural diversity of the riverine wetlands .and -to improve the general wildlife 'habitat particularly for birds. The structural diversity and evenness of the vegetated classes relate to the-amount of niches available. in an area(MDT Montana `1Vetland.Assessment Method 1999). More potential niches become Mitigation Plan,- L,AurEl clew sfebdGU2siop. S available as more habitat layers. occur. The number of wildlife species increases with .a corresponding increase in structurally complex habitats(Cooperrider et al. 1986). Baxter Creels was rated as a Category III wetland with 52.4 percent of the total possible functional points. Increasing the structural diversity and removing the on-stream reservoir would raise the.General.Fish-and Aquatic Habitat rating from low to high; the Flood Attenuation rating from low to moderate, the Short-and Long Term storage rating from low to moderate; and the rating for Sediment,Nutrient,-and'Toxicant Retention from,moderate to high., The total potential functional lift would be -ari additional 1.4 functional points, -increasing the total possible functional points from 52 A percent to 53.8 percent. Enhancement of 5.4 acres of Baxter Creek will provide 1.35 acres of mitigation credit at a ratio of4:1. Enhancement of 0.17 acres of the Baxter Ditch wetland corridor will provide 0.0425 acres of credit at a 4:1 ratio. .An 8.5-acre, 50-foot wide upland buffer or watercourse setback will be.established on each side of the Baxter Creek.:and Baxter Ditch channels. The slopes in the upland buffer are one to two percent and the vegetation coves- is herbaceous. A trail system-will be constructed at the outside edge of the buffer. The watercourse setback area and the Baxter Creek riparian corridor will be designated as dedicated parkland under the plat approval. The designation prohibits any buildings or physical structures except accessories to the provision of recreation, including but not limited to benches., picnic tables, or interpretive signage (Bozeman Unified Development Ordinance Xnuary 2004). Short-tenn maintenance of the parks will be the responsibility of the homeowners' association. Long-term maintenance will be the city's responsibility once a city- wide parks maintenance district is formed. The city enforces building setbacks.and restrictions through required building permits and review. The homeowners association will:enforce building restrictions through design review. The hydrogeomorphic class of Baxter Creek and Baxter Ditch is Iower,perennial riverine wetland. Dominant water sources are overbank flow from.the channel or subsurface hydraulic connections between the stream channel and wetlands. The following functions are detailed in the Montana Department of Transportation (MDT) form authored by the Montana Inter-Agency Wetland Committee and revised in May 1989. The goad of onsite compensatory mitigation will be to ensure"no net loss" of wetland area within the proiect boundaries and to increase the valite .of the following-functions. 1.

The south wetland encompasses-.0.9 acres of shallow open water pools and tloodplain vegetated with wetland sod mats and-a native .seed mix. The north wetland encompasses 0.86 acres.of floodplain"that was revegetawd with a native seed mix. The-outside bend adjacent tothe north wetland was planted with.50 native willows in summer 2008. Clusters of trees and shrubs will.be planted within the wetland.as part-of the enhancement of Baxter Creek. The enhancement of Baxter.Creek will be completed in 2009 or 2010 depending on the,economy and approval of the preliminary plat acid 404 permit. Trees and shrubs will be planted in early spring or early fall when the plants are dormant.(Section 3.0—Revegetation Implementation), The primary goal of the enhancement project is to increase the structural diversity of the Baxter Creek corridor by planting native trees and shrubs. The stream channel is permanently flooded. The wetland plant materials list (Table 1 — Appendix A) :identifies species that torlerate:fluctuating levels of soil saturation and inundation, aid in soil stabilization, add species diversity, and provide food and cover for wildlife particularly birds. An upland buffer will be established at the edge of the riverine fringe associated with Baxter Creek and Baxter Bitch. 'The water quality buffer will be a 50-foot wide strip vegetated with herbaceous species and clusters of woody trees and shrubs. Baxter Creek and the upland buffer will be dedicated"as parkland for the City of Bozeman. '2.1 REVEGETA.TI®N DF-SIGN Existing groundwater levels will dictate the.location,and selection of woody species and plant materials. The plant selection was based on existing native vegetation and existing topographical, hydrological, and soil .conditions. The design uses species identified during the wetland inventory. Additional native wetland plants indigenous to the ,area wefe selected to increase diversity and to fill anticipated hydrological niches within the constructed wetland areas. Table LO of Appendix A includes a comprehensive species last that summarizes common names of the selected species and the anticipated hydrological planting zones,.plant=sources,and spacing requirernents for the -treees and shrubs. Tables 2.0 and 3.0 provide seed mixes for disturbed wetland and upland areas, respectively. Planting Guidelines addressing site preparation,planting holes,and seeding methods are included in Appendix A. Live Plant Materials Woody plant species will be planted from containerized 1-to 15-.gallon.or ball and blarlap (B&B) nursery stock .depending ait availability and cost. Base flow groundwater levels will dictate the location of individual species. Approximately 24 clusters of containerized plants will be.installed along the Baxter. Creek corridor to simulate natural plant communities. Plant clusters will contain nine to.fourteen plants., Vetland clusters in.the transition areas will consist of black cottonwood (,Populus tfichocarpa), quaking aspen (Populous tresnuloides), -red-osier dogwood (Cornus stalenffera), and/or golden currant (R bes aureum). The spacing on the black cottonwood,quaking aspen,red-osier dogwood,and.golden.currant is 20 to 30 feet, 15 feet,6.to 8 feet, and 3 to 44 feet, .respectively. Clusters near the stream channol will consist of black cottonwood, Booth, -Bebb, and/or Pacific willows (Salix boothi, bebbiana, lasiwdra, respectively.),-and red-osier dogwoods. The spacing on the Booth,Bebb,and Pacific willows is 6 to 10 feet; 10 to 15 feet, and. 6 to-20 feet, respectively. Upland clusters will Contain common chokecherry (Prunus virginiana)., 'Western serviceberry(Amelanchier. .alriffolfix—UPL), Wood's rose (R`osa woodsli), common snowb.erry (Symphoricarpos albus), and/or American silvecberry m4di a-tlnw Plgvb- t_aurel eilen 6ubd vL_ akt & i '(Elaeagnus comnmtata),. The 5p4cing of the plants is 8 to 10 feet, 10 to 15 feet,3 to 4 feet,3 to 5 feet, and 3 to 5 feet respectively. Seed Mixes The seed mix for disturbed.areas within the riverine fringe focuses on species that tolerate periodic inundation and drought and.thrive in loamy soils (Table 2.0): The selected herbaceous species also aid in soil stabilization as a result of.quick establishment alid rhiz6matous root structures. Disturbed wetland areas will be seeded with tufted hairgrass (Deschampsia cespitosa — FACW), slender wheatgrass (Agropyron trachycaulurn — .FAC), tall mannagrass -(Glycerid grandis-OBL),fowl.bluegrass(Poa palustris—FAC),and slender rush(Juncus tenuis-FAC), Disturbed.or bare areas within the buffer will be planted with a native upland seed mix comprised of slender wheatgrass, Canada wildzye .(Elynzus Canadensis — FAC), sheep fescue (Festuca ovina - NL), Western wheatgrass (Agropyro smithii— FACU), Canada bluegra$s(Poa compressa— FACU), and streambank wheatgrass (Agropyron ripariunz—NL) (Table 3.0). The upland trees and shrubs listed-on Table 1.0 will be planted in clusters within the buffer bone.No buildings or development except a trail will be allowed in the buffer zone. /�'1LCL�'P.E'LOY r�lah.- Laurel c,�ewsubdivisiovc 3.0 RE,VEGETATION IMPLEMENTATION l� Native trees- nd shrubs will be planted along Baxter Creek in spring or fall 2009 or 2010. The timing of the planting sequence will depend on the weather and soil conditions. The following:section describes the revegetation schedules and implementation techniques including site preparation, seeding/planting methods,planting locations and.planting density. 3.1 SCHEDULE. The revegetation schedule is based upon the assumption that planting of the trees and shrubs and seedbed preparation will be completed prior to seeding. As a general rule, seeding will take place immediately prior to the period of maximum precipitation from. October IS to May 15. Woody species will be planted while dormant prior to bud break,which is generally late April or early May. ,Alternatively, woody plant materials can be transplanted in late fall after the species.have hardened off(dormant) for the winter. The planting time-line is included in Table 2..0.

Seed disturbed Band broadcast Last task to be Do not disturb areas di di sturbed'areas P drill seed any com leted seeded areas. 3.2 SITE PREPARATION AND PLANTING MEVIODS Site Preparation The objective of site preparation. is to -facilitate vegetation success by ensuring that conditions are appropriate for seeding. Some roughness of the growth medium is;desirable for providing microsites for plant germination and growth. Excessive roughness can be-unattractive and impede plant establishment. Seedi"Is4etheds Seeding is most successful when the seed is incorporated into the soil. 'Seed germination rates increas,.e�ilotably if the seed is coveted with a thin layer of soil(/to '/z inch). Covering the seed -also protects the seed from birds and rodents. Broadcast seeding will be used in areas that are small and have limited access. Incorporate the seed into the soil after broadcast seeding by mi,agadon Nam.-Laurel vew -uhdiv,,sioPL to dragging a pasture harrow, rakes, chains, or outer implements over the soil surface. Recommended. seed rates assume that the disturbed areas requiring seeding will be small and, therefore,broadoast seeded. Broadcast rates will be red0ced by 50 percent if drill.seeding°is used. First Ga owinLr-Seasoin Results The first growing season is a critical period for seeded species. First year cover is often comprised of patches of dense growth interspersed with bare areas. Total cover typically increases notably by the second. year. Persistently bare -areas may require piling t0 reduce compaction or additional topsoil and seeding. Annual weeds are typically problematic only during the first growing season. Seedlings of desirable species rare more robust with a#'ally developed root system in the second year,which limits the encroachment of annual weeds pecies. On-site Planting A combination of 1-,.5 , and 10-gallon and ball and burlap containerized nurssry stock will be used to provide a.range of size classes. An on-site vegetation specialist will flag the location of each woody species prior to planting. Planting specifications are included in Appendix A. 1Planting;Location and Density The planting plan will not be developed:until the preliminary plat is approved. The actual location of the trees and shrubs-may vary in the field depending on the presence of excessively saturated or rocky soils. Minimizing Post Seeding Disturbances Seeding of disturbed areas will be completed following the installation of the trees and shrubs.Foot paths.will be•established to minimize traffic. 3.3 IRRIGATION Woody species may require irrigation daring the summer .months of the -first year fallowing transplanting,. The landscape contractor will irrigate the woody-species manually as needed throughout the first growing season(from June through early•ueptember). 3.4 WE, CONTROL Weed control is critical before and during the first year when the:-water levels vary leaving. the ground surface exposed, The contractor will be, responsible for the control aand eradication of nakious weeds before they seed axed before the seeding and planting period. Only aquatic-labeled herbicides will be used-within the wetland site. A Gallatin County Weed Control District Noxious Weed Management.and Revegetation Plan were submitted to the Gallatin County'Weed Control District. Morgan Hinesley receiveei a license to spray-weeds in 2007. He sprayed Curtail in.2007 and 2009 to target then Canada,musk,. and bull thistle. The weed control program is ongoing. It has been especially effeetive'on the Aajker Creek tributary after three years of chemical control. Mitiygti©n 1�lRv�-- Lqui 2l c�leia Subduriow. 1� : .... " 3.5 SITE PROTECTION AND T'd[AMNANCE The Baxter .Greek and Baxter Ditch coxridors will be protected fi-om development by a. 50-foot upland buffer fi-om both sides of the channel. The corridor and buffer zone will be designated by the City of Bozeman as parkland. Short-term maintenance will be the responsibility of the homeowners' association. Long-term maintenance will. be the city's. responsibility once a city-wide parks rnaitttenatice district is-formed. The city enforces building setbacks and restrictions through required building permits and review. The homeowners association will enforce building restrictions through design review. . Potential problems related to weed and pest control.,predation, disease,plant mortality,etc.will be identified during qualitative monitoring(see Section 4:1)conducted annually. , MI6gation.Plan- t_acrrel clen..subdivistan. 4.0 MONITORING PLAN Planting trees and shrubs for enhancement is scheduled for 2009 or 201.0 depending on the infrastructure construction. Qualitative monitoring would commence the same year to identify any site .management problems, Quantitative monitoring will be' conducted during the growing season for three consecutive years after planting to assess the 'survival acid health of the- woody species. The monitoring parameters described below provide a means of qualitatively and quantitatively evaluating mitigation wetland performance. Monitoring wiil also yield itiforrnation, in support of post-construction contingency measures such as reseeding,replanting,weed.eontrol, and animal(pest)control. The final quantitative monitoring report for the Aajker Creek Tribulary will be submitted in 2008. ' The first year of quantitative monitoring was completed on the constructed floodplain wetlands on September 8,2008. The report will be submitted.in 2008 avith the Aajker Creek Tributary data., 4.1. QUA LITATWE MONITORING Qualitative vegetation monitoring will be used to evaluate general 'site conditions,the success of the reproductive effort,the presence of bare or eroded.zones, and the development of hydrological conditions. The information will be used to design appropriate management or contingency in. The initial qualitative monitoring.event will be completed the same year as the containerized plants are installed. Qualitative monitoring parameters will be based on field observations recorded during quantitative moriitorirtg events and will include: ® identifying the location, extent,and type of weed infestations; o noting plant damage from wildlife o noting wildlife use;and Q completing photo documentation. Photomonitoring will -be used to evaluate successional trends ..in plant growth. It will consist of phgr otoaphing the random clusters of trees and shrubs. Photographs will be taken at approximately the same time each year. 4.2 QUANTITATIVE E MONITORING Quantitative analyses-will be used to describe planting success within the specified time fi•ame., The.monitoring plan assumes that vegetation:transects will not be necessary based on the limited extent-,of seeded areas. Survival.rates and plant health for individual woody specio will be recorded.annually within the mitigation wetland and upland buffer.. Evidence.of"disease w wildlife browsing will be recorded and.addressed if accessary. 4.3 WEED MANAGEMENT A noxious weed management plan has. been developed and submitted to the Gallatin County Weed'Contro.l Board for the proposed subdivisionl The weed management plan requires an annual assessment of weed conditions and implementation of control measures. Control methods will depend on the type,'location,and.extent of'the infestations. 4.4 MONITORING NG AND REPORTING FREQUENCy Quantitative and qualitative monitoring will be conducted annually .beginning with the first growing season following the installation of the plants. Monitoring results will be summarized in a yearly report that will be submitted:to the USACE for three .years following M4tiyRtr✓.n Plan- Laurel Olen s"Wvfslon cs construction or plant installation. At the end of the three-year-monitoring period, the monitoring results will be evaluated to determine whether site conditions meet the performance standards outlined'in Section 4.5.. .4.5 SUCCESS CRI TERII:A Criteria were established to measure the success of the proposed mitigation project based .on the goals presented in Section 1.4. Performance standards.will be measured at the end of the third growing season. 1. Mortality of the.containerized trees and shrubs cannot exceed 20%. 4.6 CONTINGENCY PLANT Should the initigation areas not meet the success criteria, mferenced above, Hinesley Development will be responsible for identifying the cause of failure and developing contingency measures to remedy the problem. Potential options addressing lack of vegetation success may include replanting and weed control. The contingency plan would be developed based on specific information-and circumstances on an as-needed'basis in-consultation between the perrnittee and the USACE.

The proposed development is a 15.6.96-acre site located on the north side of Durston Road approximately 1300 feet west of the intersection of Durston Road and Cottonwood Road. The proposed.-residential and commercial-subdivision will be constructed in four phases. The proposed development will consist of a variety.of buildable lots for single and multi-faaxzily use. The commercial .area is proposed for Neighborhood Service area B1 zoning. The proposed subdivision will also incorporate open spaces and park areas. Please refer to the Figure One zone neap for lot locations and area breakdown per zoning elassif cation. Field Work Allied Engineering Services, Inc. surveyed cross-sections of the creeks in September, October -and November of 20Q1 using survey grade Global Positioning Systern (GPS) equipment. Figure Two shows 'the location of these sections. Additionally, -the culvert conveying Baxter Creek- across Huffine Lane was surveyed. City ofB:azeman BM#717,the northwest bon liolton fire hydrant, (elevation 4793.1'8) located northeast of the intersection of West Babcock and North Ferguson is the-elevation benchmark for the project. Hydrology The historical .drainage basin for Baxter Creek is shown overlaid. upon -a United States Geological Survey (USGS) topographic map in Figure Three. The:hlistorical_drainage area for Baxter Creek -is approximately 2.0 in? upstream of the project site.

Through slide gates located.on the cana], the Farmers-Canal Company .can discharge water to the Baxter Creek drainage. Furthermore, ponds, culvert crossings, ditches, roads,. and other obstructions have significantly altered the historical drainage network for the basins. Refer to Figure Four for an annotated aerial photo showing.-some of the features of the basins. Three different hydrologic m.ethads were used to estimate historical runoff. The methods used are. Rational, SCS TIC,755, and the USES regressions equations given in WWater-Resources lnvestigations Report 92-4048 (Omang,. 1992). The applicability of. .each of these methods depends upon drainage area and other factors. For example, the TJSGS regression equations do not consider average slope.of the basin, and therefore would tend to overestimate peals flows for relatively'flat basins (which these.are). The standard errors.of prediction of the USES regression equations range from 22 to 12-8 percent. Both the Rational method and SCS method require time of concentration (tc) as an input. The 'time of .concentration, to was estimated using Manning}s kinematic solution along with Manning's equation for open channel flow. Development in the basins both increases and decreases the time of concentration as compared to the pre-development condition; Tc is decreased by clearing brush, paving, drainage ditches, etc., and increased by detention from roads, ponds and other obstructions. A detailed analysis accounting for detention.and ditches is beyond the scope of this project. The Rational method requires the rainfall intensity to correspond to a duration equal to to. The required intensity value was estimated from the Jntensity-Duration-Frequency (IDF) equations given -on Figure 23 of the Bozeman Stormwater Master Flan (1982). Characteristics of the drainagebasin are provided,in Table I. Area Curve Rational Te Ib (acres) Number C (Hours) Baxter Creek Basin 1263 74 0.3 3.2 Baxter Creek Basin South of 700 74 0.3 2.3 Huffine Table 1. Drainage Basin Characteristics. For analyzing historical flows, the SCS method is selected as it best takes into account the various local variables that effect runoff. The .default SCS rainfall distribution for Montana.is . Type II. Based on the criteria in section 7:20.3 of the MDT Hydraulics manual', an SCS Type I distribution was determined to be more appropriate for use in Bozeman. Allied Engineering Services, Inc. Page 5 Bob Murray Februw y 4,2002 Project:00-185 This is based on the ratio of the local six and twenty-four hour precipitation values given in the NOAA atlas. The peak flows predicted by the, Rational Method are significantly higher, particularly for frequent storm events. One reason is that the Rational method does not account for infiltration in a way that would differentiate the increased percentage of infiltration that occurs for smaller (more frequent) storm events. For example, for a given basin, there is some threshold storm event for which smaller storms will`yield practically no runoff. This is modeled by an initial abstraction in the SCS method but is not predicted by the rational method. In summary, it is our opinion that the SCS method is the most applicable for estimating historical "run on"flows from the upstream basin. Results of the hydrologic modeling are provided in Table Two. Appendix A contains design notes and information used for the hydrologic analysis. Note that the computer program Culvert Master was used to calculate the SCS and Rational method given the following inputs: 1)SCS - basin area, SCS rainfall type I, time of concentration, curve number = 74, and the 100-year 24- hour precipitation depth (from NOAA) =2.8 inches;2) Rational—basin area, C coefficient, IDF data from the City of Bozeman Storm Water Master Plan, time of concentration, and a 100-year return.period. In determining the curve number for the SCS method,we assumed a pasture cover type in good hydrologic condition and a hydrologic soil group C (see Appendix C for soils information).

We also looked at the possibility of increased peak flows during a 100-year stoma event higher than those calculated using standard hydrologic methods (SCS) due to the altered characteristics of the basin. Specifically, we investigated the possibility of higher peak flows occurring due to Farmers Canal discharging water into the basin; say by an overtopping or breaching of the canal bank. While we are unsure of how much flow Farmers Canal could discharge into the basin,we decided to look at the capacity of the culvert which conveys Baxter Creek under Huffine Lane. We obtained the hydrologic analysis (see Appendix B) done by the Montana Department of Transportation (MDT)in 1994 for the Huffine Lane rebuild project. In their hydrologic analysis for the culvert design,MDT calculated the following: a Base Flood (100-year) at culvert= 90 efs Overtopping Flood (overtops basin divide located approximately 320 feet to the west) _ 122 cfs with a frequency of< 0.21/o (greater than 500 years) Allied Engineering Services,Inc. Page 7 Bob Murray Project:00-185 February 4,2002 O Headwater at Overtopping=5.3 feet s Channel capacity= 65 cfs ® Design Culvert: 54" CMP We field verified a 54" CMP culvert in place with the following characteristics: ® Length= 13 9 feet a Invert Elevation In=4846.02 feet ® Invert Elevation Out=4843.72 feet Using the computer program. Culvert Master by Haestad Methods, we calculated a headwater depth of 5.4 feet at a flow of 122 cfs which closely matches the overtopping analysis done by MDT. Using the SCS method we also calculated a 100-year base flood of 82 cfs at the culvert which is reasonably close to the base flood flow of 90 cfs calculated by MDT. This number (82 cfs) was used to estimate the proportion of the flow generated by the basin upstream of Huffine and downstream of Huffine. Considering the possibility of additional flow fxom Farmers Canal, a base flood of 169 cfs at the project site was used for our hydraulic analysis. We arrived at this by adding the overtopping flow of 122 cfs conveyed under Huffine Lane to the flow contribution north of Huffine Lane, 47 cfs (129 cfs for entire basin— 82 cfs at Huffine culvert=47 cfs). Hydraulics Water surface profiles for the proposed development were estimated using the U.S. Army Colp of Engineers' HEC-RAS River Analysis System computer Program, Version 3.0.1 (March, 2001). The geometry used in the model assumes post-development conditions which incla:de.the following: Five roads crossing Baxter Creels as shown in Figure One. ® Culverts extend 15 feet beyond the road right of way. The following right of way widths were assumed: o Oak Street: 120 feet o Glen Ellen Drive: 60 feet o Annie Street: 74 feet o GIenwood Drive: 60 feet o Durston Road: 120 feet ® Removal of the existing pond and outlet structure located on the south end of the project and construction/restoration of the stream channel in this area. Allied Engineering Services,Inc. Page 8 Bob Murray February 4,2002 Project;00-185 The channel portion of the cross sections at the upstream and downstream end of the culverts were interpolated from the field surveyed sections while the overbank portion of the sections was taken from the topographic surface generated from the field survey. Cross sections 40,420, 540, 1110, 1330, and 1340 were interpolated entirely from surveyed field data. The selection of Marnring's n values was based on Table 5-6 on page 112 of Chow's text OpL'12-ChQ)171EI Hydraulics (Chow, 1959). The following ii values were used: Channel= 0.04 • Overbanle(high grass) = 0.045 Overbank (brush) =0.09 Overbank (intermittent brush) 0.06 Concrete Pipe= 0.013 The model was run in the mixed flow regime with starting conditions at the downstream and upstream end of the model set at normal depth with slopes of 0.0075 and 0.02 ft/ft,respectively. A mixed flow regime was used because both supercritical (in and downstream of the culverts) and suberi.tical flow occur in the model. As discussed in the hydrology section of this report, a base flood of 169 cfs was used in the model. To account for possible future development outside of the stream corridor, encroaclunent method number one was run in HEC-RAS with encroachments set at the stream corridor boundary (i.e. at the property boundary between the stream corridor and adjacent private/park lands). As shown in Figure Five, the un-encroached base flood only goes outside the stream corridor significantly in the backwater areas upstream of culverts. There was no significant difference between the wafter surface elevation of the encroached and un-encroached models. The data for the encroached and un-encroached runs is provided in Appendix D. Reinforced concrete pipe (RCP) culverts were used in the model as they are required by the City of Bozeman (page 47 of City of Bozeman Design Standards and Specifications Policy,2001), To evaluate backwater upstream of road crossings, we modeled three culvert configurations for the road crossings: 1. Two 48-inch RCP culverts 2. Two 58.5 x 36 inch reinforced concrete pipe arch (RCP.A.) culverts 3_ One 88 x 54 inch RCPA culvert In determining the floodplain elevations for our study, we checked the above three options for each crossings and used the option that resulted in the highest water surface upstream of each crossing. We chose not to consider more than two culvert barrels to avoid the need to widen the stream bed (generally 8 to 18 feet from bottom of bank to bottom of bank). Of course larger culverts would also be acceptable but would cost more. i Allied Engineering Services,Inc. Page 9 Bob Murray February 4, 2002 Project:00-185 The existing culvert at Durston Road is a 48-inch corrugated metal pipe (CMP). We also evaluated the culvert crossings in HEC-RAS using one 48-inch RCP culvert to match the size of the existing culvert at Durston Road. Using one 48-inch RCP culvert at the road crossings increased the backwater approximately one to two feet compared to the culvert configurations listed above. Figure Five shows .a plan view of the site with the un-encroached base flood boundary and un- encroached base flood contours. Note that the flood elevations in Figure Five are the maximum of the three water surface elevations calculated for the three above listed culvert configurations. Appendix D contains summary printouts from the HEC-RAS program.. In the HEC-RAS output, profile one refers to the un-encroached geometry and profile two refers to the encroached geometry. Unfortunately, there is no historical data (flows and flood elevations) to calibrate the mode] for high flow. If data existed to calibrate the model, the Manning's n values could possibly change. Increasing Manning's n values would increase the base flood elevation. We believe the Manning's n values used in our model are reasonable. Recommeiadations We recommend installing one of the following culvert configurations at the five roadway crossings: 1. Two 48-inch RCP culverts 2. Two 58.5 x 36 inch reinforced concrete pipe arch(RCPA) culverts 3. One 88 x 54 inch RCPA culvert With the exception of road. crossings, we also recommend keeping the stream corridor in a natural condition free from obstruction (e.g. buildings and constructed fill other than road crossings). Although no floodplain is officially designated for Baxter Creels within the subdivision area, all floodplain_regulations contained in the City of Bozeman Zoning Ordinance should be followed. For residential structures within the floodplain, section 18,44.270.0 of the City of Bozeman Zoning Ordinance states that "The New construction, alterations, and substantial improvements of residential structures including manufactured homes must be constructed on suitable fill such that the lowest floor elevation (including basement) is N10 feet or more above the base flood elevation. The suitable fill shall be at an elevation no lower than the base flood elevation and shall extend for at least fifteen feet, at that elevation, beyond the structure(s) in all directions." Section 18.44.270.D goes on to say, "The new construction, alteration; and substantial improvement of commercial and industrial structures can be constructed on suitable fill as i Allied Engineering Services,Inc. Page 11 Bob Murray February 1,2002 Project: 00-185 specified in subsection C of this section. If not constructed on fill, commercial and industrial structures must be adequately flood proofed to an elevation no lower than two. feet above the base flood elevation." At a minimum, we recommend,that structures adjacent to the stream corridor regardless of whether they are in the base flood area (see Figure 4)be constructed as outlined above and in.the zoning ordinance.

Allied Engineering Services, Inc. 32 Discovery Drive Bozeman, MT 59718 Re: Laurel Glen Subdivision Flood Hazard Evaluation Dear Paul; As we recently discussed on the telephone, Baxter Creek's historical drainage basin up gradient of the subject property is indeed less than the 25 square mile threshold referenced in our subdivision'code, However, the Farmers Canal collects drainage from a very large portion of the up gradient Gallatin Valley between Bozeman and it's Gallatin River in take. Baxter Creek is routinely used by the Farmers Canal Company during flood events as a "blow-off" drainage for significant runoff flows it recieves. Thus, the effective drainage for Baxter Creek can be significant and it is therefore important that the hydraulic and topographical characteristics of the subject site be assessed and addressed in the development of the subject site. As such, please expect that City Staff will ask that the hydraulic profile and limits of impact of a 100 year equivalent event be provided with the subdivision submittal, Pursuarft to the City's Subdivision Code and in that the lay-out of lots and other improvements may be impacted by the flood limits of impact, the assessment needs to be completed and provided with the preliminary plat submittal.

The estimates are used in land use planning that involves lineering considerations. lrologic soil groups are used to estimate runoff from precipitation. Soils not protected by vegetation are :ignpd to one of four groups. They are grouped according to the infiltration of water when the soils are thoroughly and receive precipitation from long-duration storms. The four hydrologic soil groups are: Group " All. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group "B". Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately Eine texture to moderately coarse texture. These soils have a moderate rate of water transmission. cup "C". Soils having a slow infiltration rate when roughly wet. 'These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine .texture or fine texture. These soils have a slow rate of water transmission. Group "D". Soils having a very slow infiltration rate (high runoEE potential) when thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential, soils that have a permanent high water table, soils that have a claypan or clay layer at or near the surface, and soils .that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. a soil is assigned to two hydrologic groups in this report, the first letter is for drained areas and the second for undrained areas. Flooding, the temporary inundation of an area, is caused by overflowing streams, by runoff From jacent slopes, or by tides. Water standing Ear short periods after rainfall or snowmelt is not considered coding, nor is water in swamps and marshes. This report gives the frequency and duration of flooding and time of year when flooding is most likely. Frequency, duration, .and probable dates of occurrence are estimated. _quency is expressed as "None", "Rare", "Occasional", and "Frequent". "None" means that flooding is not probable; are" that it is unlikely but possible under unusual weather conditions; "Occasional" that it occurs, on the arage, once or less in 2 years; and ('Frequent" that it occurs, on the average, more than once in i years. ration is expressed as "Very briefII if less than 2 days, "Brief" if 2 to 7 days, "Long" if 7 to 30 days, and "Very a7•" ore than 30 days. The information is based on evidence in the soil proEile, namely thin strata of gravel, 41 i or clay deposited by floodwater; irregular decrease in organic matter content with increasing depth; of distinctive horizons that form in soils that are not subject to Elooding. . Also considered are local Eornation about, the extent and levels of flooding and the relation of each soil on the landscape to historic Eloods. U.S. DEPARTMENT OF AGRICULTURE PAGE. 3 OF 3 URAL RESOURCES CONSERVATION SERVICE 11/8/O1 WATER FEATURES Endnote -- wATER FEATURES•-Continued Information on the extent of flooding based an nail data is less specific than that provided by detailed engineering surveys that delineate flood-prone areas at specific flood frequency levels. High water table (seasonal) is the highest level of a saturated zone in the soil in most years. The depth to a seasonal high water table applies to undrained soils. The estimates are based mainly on the evidence of a saturated zone, namely grayish colors or mottles in the soil. Indicated in this report are the depth to' the seasonal high water table; the kind of water table, that is, "Apparent", "Artesian", or "Perched"; and the months of the year that the water table commonly is high. A water table that is seasonally high for less than i month is not indicated in this report. An -Apparent" water table is a thick zone of free water in the soil. It is indicated by the level at which water stands in an uncased borehole after adequate time is allowed for adjustment in the surrounding soil. An "Artesian" water table exists under a hydrostatic beneath an impermeable layer. When the impermeable layer has been penetrated by a cased borehole, the water rises. The final level of the water in the cased borehole is characterized as an artesian water table. "Perched" water table is water standing above an unsaturated zone. In places an upper, or "Perched", water is separated from a lower one by a'dry zone. Only saturated zones within a depth of about 6 feet are CJ :ted. Ponding is standing water in a closed depression. The water is removed only by deep percolation, transpiration, evaporation, or a combination of these processes: This report gives the depth and duration of ponding and the time of year when ponding is most likely. Depth, duration, and probable dates of occurrence are estimated. Depth is expressed as the depth of ponded water in feet above the soil surface. Duration is expressed as "Very brief" if less than 2 days, "grief" if 2 to 7 days, "Long" if 7 to 30 days, and "Very long" if more than 30 days. The information is based on the relation of each soil an the landscape to historic ponding and on local information about the extent and levels of ponding. �jm,�1,4, Fga vr Ufl! 14'Ali WN pt V. ok 4 q VIP I TO t�W.
