Environmental Assessment/Glacier Town CenterEnvironmental Assessment Glacier Town Center Kalispell, Montana Prepared for: CTA Architects and Engineers, Inc. for Wolford Development Montana, LLC, Inc. Prepared by: Hyalite Environmental, LLP P.O. Box 90 Gallatin Gateway, MT 59730 (406) 763-4228 June 2007 Executive Summary The Glacier Town Center is proposed for development on approximately 485 acres north of Kalispell, located north of West Reserve Drive, and between the Whitefish Stage Road and US Highway 93. The project includes: commercial, mixed use, multi -family residential, single family residential, park and open space areas. It is anticipated that this project will be annexed to the City of Kalispell. Phase I of the project is anticipated to provide 1,005,400 square feet of commercial space on 109 acres, and 28,800 square feet of office/professional space on 3.2 acres, with an additional 17 acres dedicated to open space and parks. Phase I of the project is proposed to begin construction in 2007/2008, with subsequent development of Phases II through V extending to 2020. The full proj ect is anticipated to provide 1,575,943 square feet of retail uses and 246,686 square feet of office space, totaling 1,822,629 square feet of commercial space. The proposed project will require changes or relaxations to zoning ordinances as described in other portions of this project application to the City of Kalispell. With the proposed changes or relaxations to zoning, the proposed proj ect will be otherwise compliant with Kalispell growth policy. There will be No Significant Impacts to: • Historic, Paleontological, Archaeological or Cultural Environment • Natural Environment: Wetlands • Natural Environment: Soils and Geology • Natural Environment: Threatened and Endangered Species, MT Species of Concern • Natural Environment: Air Quality • Public Health and Safety There will be Minor Detrimental Effects to: • Agriculture —Approximately 476 acres will be removed from agricultural use. • Natural Environment: Topography — There will be some cut -and -fill and grading required for effective use of the property. • Natural Environment: Vegetation, Wildlife and Wildlife Habitat — There will be increased anthropomorphic impacts on the parcel, and loss of field habitat (tilled and irrigated hay and grain fields). ii Environmental Assessment Hyalite Environmental, LLP Glacier Town Center, Kalispell, Montana June 2007 There will be Minor Positive Effects to: • Agricultural Water User Facilities The project will not likely use the existing surface water rights that are currently used for agricultural irrigation. • Natural Environment: Vegetation, Wildlife and Wildlife Habitat— Approximately 72.3 acres, 69 of which are currently agricultural land, will be converted to open space / park with native species landscaping. There will be an increase in diversity of habitat type due to incorporation of forbs, shrubs and trees throughout the development. Fifteen hundred linear feet of the Stillwater River streambank and riparian corridor will be preserved and protected. • Natural Environment: Ground and Surface Water Quality —The project is designed to ensure treatment of storm water runoff before infiltration to ground water or conveyance to surface water, which is an improvement over the current agricultural impacts upon ground and surface water. It is anticipated that the Minor Detrimental Effects will be mitigated and / or offset by the Minor Positive Effects. There will be a somewhat neutral impact related to the shift of wildlife habitat from the current vegetation of the irrigated fields to the native species in the mixture of open space, vegetated buffer zones, park, landscaped developed space There will be Significant Impacts to: • Local Services: Education • Local Services: Road maintenance • Local Services: Water, Sewage and Solid Waste Facilities • Local Services: Fire and Police Protection The project is designed to accommodate projected / anticipated growth (Kalispell, City Planning Department, 2003 and 2007). These Significant Impacts will be mitigated through design of the project in a manner compliant with the City of Kalispell and Flathead County growth policies, and Evergreen / Stillwater Zoning District. Significant Impacts will be further mitigated through improvements that will be paid for by the development (such as improvements to the adjacent roadways), fees, and increased tax revenues. The City will gain the economic benefit of jobs created, a new community center with park lands, and the draw of a new retail facilities.

Location of vegetation communities and wildlife habitat on preliminary plat v Environmental Assessment Hyalite Environmental, LLP Glacier Town Center, Kalispell, Montana June 2007 Introduction An Environmental Assessment (EA) has been performed for the proposed Glacier Town Center development, Kalispell, MT. The EA was performed by Hyalite Environmental, LLP (Hyalite), Bozeman, MT, for CTA Architects and Engineers, Kalispell, MT. The development proposal is being made by Wolford Development Montana, LLC. Hyalite personnel performing the work were Chris Thelen, P.E., and Carol Lee -Roark, Ph.D. Field investigations were conducted April 16 through 18, 2007. The objective of the EA was to examine potential environmental impacts of the proposed project, providing the design team with input for design and providing information to the City of Kalispell for review of the proposed project. The EA was conducted following the City of Kalispell Title 24A Subdivision Regulations Ordinance No. 1238, Appendix B: Environmental Assessment (adopted May 6, 1996, and as subsequently amended through May 2007). The proposed project site is approximately 485 acres on the northern outskirts of Kalispell. The site is bound on the south by West Reserve Drive, on the west by US Highway 93, and on the east by Whitefish Stage Road. The northern boundary coincides with the extension of Rose Crossing Lane in the northwestern portion of the site and for the remainder of the site, the northern boundary is one quarter mile north of that road. The site is located in Sections 19 and 30, Township 29 North, Range 21 West, Montana Principal Meridian (Figures 1 and 2) [See also Exhibits A and B]. The proposed Glacier Town Center is a mixed -use development with major components that include commercial, residential, office, and open -space. Figure 3 is a preliminary conceptual design diagram of the proposed project. [The most up-to-date version of the proposed project design is included as Exhibits S, T and U.] The Glacier Town Center will have architectural themes that connect it to and honor the historical and cultural heritage of the Flathead Valley. The Glacier Town Center will be tied to the previously existing surrounding residential and commercial land use areas and historic downtown Kalispell through a network of pedestrian and bike trails, as well as upgraded roads that are designed to accommodate the projected growth of the area, as outlined in the Kalispell Growth Policy 2020 (February 18, 2003, and as subsequently amended through May 2007). The proposed area of development, land use types, and density of proposed development are explained in text and tables in other parts of the document that is being submitted to the City. Distribution of land types and amenities are shown on Figure 3. Aerial photos from 2005 show approximately 140 acres of wheat field, and 330 acres of alfalfa or hay, and 13 acres of fallow and/or un-farmed land. The property in the proposed project site is owned by two entities: 478.02 acres are owned by the Stillwater Corporation, for which Roger Claridge, of Kalispell, MT, is the registered agent; and 4.28 acres are owned by Edwin and Janet Spannuth, of Lakeside, MT. The aerial photograph in Figure 2 shows that there are currently no structures on the land. Table 1 lists the parcels included in the proposed project site by lot, geocode, present tax classification, and area of each parcel. Table 1.

All other parcels are owned by Stillwater Corp. Source: Montana Department of Administration cadastral database, February 2007. The zoning of the proposed project site, which is located in the Stillwater and Evergreen and Vicinity Zoning Districts, is SAG-5 (Suburban Agricultural), SAG-10, AG-20 (Agricultural), R-1 (Residential) and B-2 (General Business) (Flathead County Commissioners Resolution No. 797CN, November 13, 2003) [See Exhibit D]. It is anticipated that the area of the proposed Glacier Town Center will be annexed to the City of Kalispell, and that there will be some changes to zoning [See Exhibit E]. In the Kalispell2020 Growth Policy (Kalispell, 2003 and as subsequently amended), the area of the proposed development is specified as "KN-1", Kalispell North Mixed Use Area. This proposed project site (with the exception of the Spannuth parcel) has been the subject of ongoing public and political discussions since 1999. Legal actions have been taken and compromises reached in order to accommodate the input of many special interest groups, as well as the goals and viewpoints of residents of Kalispell and the surrounding areas. The plan presented here reflects input that Wolford Development and their land planning and design engineering firm, 2 Environmental Assessment Hyalite Environmental, LLP Glacier Town Center, Kalispell, Montana June 2007 CTA Group, have sought from stakeholders and regulatory agencies associated with the proposed project. Most significantly, the proposed project has been accepted by the local landowners, as reported in the article by Spence (2007) in the Daily Interlake on February 14, 2007. Environmental Assessment Hyalite Environmental, LLP Glacier Town Center, Kalispell, Montana June 2007 Part I — Property Description Part I -- Section 1. Surface Water Figure 4 shows surface water features on the proposed project site. Figure 5 shows delineated wetlands and waters of the US on the proposed project site [See also Exhibits S, T, and U]. Natural surface water features at the site include approximately 1,500 feet of the eastern bank of the Stillwater River. 1.33 Acres of the proposed project site fall within the FEMA (1992) 100-year floodplain of the river. There are no irrigation water conveyance ditches on site, and the small area of the parcel that is adjacent to roads is characterized predominantly by gently sloping roadside areas and ditches that do not hold standing water or pond surface water runoff for long periods of time (days). Irrigation water is conveyed on site by underground pipes. No stream bank alterations or modification of any natural surface water body are planned for the proposed project. There will be no impacts to the Stillwater River riparian corridor, nor any other waters of the US. There are 0.32 acres of jurisdictional wetlands associated with the surface water features on the site, as listed in Table 2. All of the jurisdictional wetlands are fringe (riparian) scrub/shrub wetlands associated with the Stillwater River riparian corridor. The Wetland Delineation and Waters of the US Assessment Report for the proposed project site is included as Appendix F of this submittal package of materials. Table 2. Summary of Wetlands / Waters of the US Wetland Design Jurisdictional Areal Designation Type Accomodation or Status Extent (Figure 5) Impacts WL-1 Riverine Jurisdictional 0.32 acres 50-foot setback There will be no actions taken within FEMA 100-year floodplain and no impacts will be made to the identified Jurisdictional Wetlands. There are two areas on the site where mid -winter and early spring snowmelt and/or rain over frozen ground can create intermittent ponding or surface water runoff flows. The area in the northeast in the vicinity of the windbreak trees may have standing water until the ground thaws (personal communication, Robin Street, in Hyalite Environmental, LLP, 2007). A portion of the site drains to Environmental Assessment Hyalite Environmental, LLP Glacier Town Center, Kalispell, Montana June 2007 the southwest to a drainage swale / gully leading to the Stillwater River through the adj acent Glacier Memorial Cemetery (personal communication, Glacier Memorial Cemetery in Hyalite Environmental, LLP, 2007). Neither of these areas of surface water remain during the growing season, and previous farmers who have raised crops on the site (personal communication, Robin Street and Steve Striech, in Hyalite Environmental, LLP, April 2007) have found that the site is dry and well -drained and that there is nowhere that they can not get heavy equipment into the fields due to saturated soils during the growing season. A Hydrology Report with additional information concerning current surface water drainage of the site is included in Appendix G. The only potential environmental permitting anticipated to be required for the proposed project is Montana Point Discharge Elimination System (MPDES) permitting associated with any detention pond discharge of surface water runoff. A Surface Water Pollution Prevention Plan (SWPPP) will need to be filed with the Montana Department of Environmental Quality for any construction activities. There are no planned impacts to the Stillwater River, Stillwater River floodway, or associated wetlands. It is anticipated that the court -mandated development of a watershed plan and Total Maximum Daily Loads being voluntarily implemented by the community and facilitated by the Montana Department of Environmental Quality and US Environmental Protection Agency will be sufficient to achieve compliance with water quality standards and mitigate impacts that are not related to the proposed potential development. Part I -- Section 2. Ground Water Figure 6 shows the location of ground water wells (approximate) and static water elevation data available for the site vicinity from the Ground Water Information Center (GWIC) database of the Montana Bureau of Mines and Geology. Shallowest groundwater is located close to the rivers, with groundwater eight feet below the ground surface in a well near the Whitefish River (July 30,1990) and 10.8 feet below the ground surface in a well near the Stillwater River (October 25, 1998). Deepest static ground water levels have been measured in wells located approximately mid -way between the two rivers. This area mid -way between the two rivers is located near the eastern boundary of the proposed project site, where static water levels have been measured at 127 feet below the ground surface (December 16, 1996, and April 14, 2004). The Montana Bureau of Mines and Geology (MBMG) has carried out regional groundwater investigations in the Flathead Valley (LaFave and others, 2004). These regional studies characterize the area as dominated by a deep, continuous, confined aquifer that is approximately two -hundred feet deep in the vicinity of the site. Recharge to the deep, confined aquifer is from the mountains surrounding the Flathead Valley. 5 Environmental Assessment Hyalite Environmental, LLP Glacier Town Center, Kalispell, Montana June 2007 Additional site ground water data derived from soil borings and monitoring wells, is further discussed in the Hydrology Report (Appendix G) and Preliminary Geotechnical Report (Appendix H) included with this package of submittal materials. The Preliminary Geotechnical Investigation performed for the property in July 2003 measured saturated soils at depths ranging from 4.5 to greater than forty feet below ground surface. Ground water was encountered in only one of the twenty-three test borings included in that report, at 16.8 feet below ground surface. Ground water was below the bottom of the other borings (total boring depths of eleven to 40 feet). Additional shallow monitoring wells that were installed across the northern portion of the property in 2004 recorded 68 wells out of the 75 wells installed as dry (Flathead City/County Health Department, 2007). The remaining 7 wells recorded ground water levels at approximately 10 feet or greater. None of an additional sixteen soil borings drilled to 48 inches below the ground surface in March of 2004 encountered ground water. The Hydrology Report (Appendix G) reports that there is a shallow perched water table in the northeast corner of the property. The area has been delineated with piezometers and is approximately 60 acres, consistent with that previously defined by other authors. The minimum depth to the water table observed during the 2007 monitoring period was approximately 6 feet (70 inches), which occurred on April 30, 2007. Monitoring data are included in the Hydrology Report (Appendix G). It is proposed that the Glacier Town Center be annexed to the City and connected to City water systems, as discussed in the Utility Report (Appendix J) included in this package of submittal materials. There may be short-term dewatering associated with facilities construction. The only long-term consumption of ground water resources from the site will be that related to evapotranspiration from vegetation included in the landscape design. During later phases of development, a ground water well may be installed on the Glacier Town Center site to supply additional water and water pressure to the city water lines. The Glacier Town Center has been specifically and carefully designed and engineered to avoid depletion or degradation of ground water or surface water resources, as discussed / presented in the Hydrology Report that has been included in this package of submittal materials (Appendix G). The site grading and the storm water runoff plan have been developed to ensure that storm water runoff from the site will be appropriately treated (Appendix K). Recharge of the deep ground water aquifer is from the mountains surrounding the Flathead Valley. There will be no impacts, depletion or degradation of ground water in the deep alluvial aquifer. Recharge of the shallow perched water table (found on 60 acres of the northeastern portion of the site) is primarily from snowmelt infiltration. The stormwater drainage design will minimize collection and ponding of snowmelt in that area, so that the shallow perched water table may be somewhat impacted by the proposed development. Structures in the vicinity of the perched shallow 6 Environmental Assessment Hyalite Environmental, LLP Glacier Town Center, Kalispell, Montana June 2007 aquifer will be designed to accommodate that relatively shallow (six-foot below ground surface) ground water. Part I -- Section 3. Topography, Geology and Soils Figure 7 is a detailed topographic survey (1-foot contour interval) of the current configuration of the proposed project site. The site is located on the upland that divides the lower Stillwater and lower Whitefish river drainages. The Cover Photo from Google Earth shows an oblique aerial photograph of the site with no vertical exaggeration, looking toward the south. The confluence of the two rivers is 1.87 river miles south of the site. The lowest point on the site is approximately 2960 feet above mean sea level, in the southeast corner of the site on the eastern bank of the Stillwater River. The northern boundary of the parcel is close to 3030 feet above mean sea level (average slope of 1V:100H). The central portion of the site is a relatively flat bench at 3020 feet above mean sea level. The slope from the Stillwater River floodplain to the first terrace level is 7V:100H. There are two small conical hills within the parcel (14 and 30 acres) that rise to approximately 45 feet above the main bench, with slopes that range from 7V:100H to as much as 16V:10011. Areas of slopes >15% are identified on the Preliminary Plat (Exhibits T and U). The small conical hills have been interpreted as kame features (Preliminary Geotechnical Report, Appendix H), which are stratified supra -glacial deposits that are left as positive topographic features after glacial ice has retreated. Figure 8 illustrates the simplified regional geology of the vicinity of the proposed project site, as reported on a geologic map by Smith (2004). The majority of the site is located in glacial outwash deposits. Alluvial sediments are deposited across the floodplain of the incised Stillwater River. There are fine-grained glacial lake sediments in the central -northeastern portion of the site. These glacial and alluvial sedimentary deposits provide the parent materials for the soils that have developed at the site, shown in the published soil survey map on Figure 9. There are no areas of shallow bedrock on the proposed project site. There are two small conical hills (kames), which have areas of potentially unstable or excessive slopes. The smaller hill, adjacent to US Highway 93 (toward the northwest) will require cutting and grading for efficient and effective development of the land in the highway corridor. The larger hill, (toward the center of the parcel) will be incorporated into park / open space, relying primarily on vegetation to stabilize the slopes. There is further information concerning the proposed grading plan, and volumes / areas of cut and fill in the site grading and cut -and -fill figures (see Appendices N and O) included in the package of submittal materials. 7 Environmental Assessment Hyalite Environmental, LLP Glacier Town Center, Kalispell, Montana June 2007 There are no areas of shallow bedrock within the proposed development. There are no areas with rock falls, slides or slumps, or rock outcroppings. There is approximately 1000 square feet of a soil unit on the site that is susceptible to shrink -swell (Depew silty clay loam) (MRCS, 2007). This unit is also considered to be prime farmland, and is shown in turqouise on the map in Figure 9a. These soils will be replaced with appropriate soils if design requires structures on that area. The only soil units mapped within the parcel (MRCS, 2007) that may be highly erodible are shown on Figure 9a. The majority of area of erodible soils is on the two small conical hills, the kame desposits. There are two additional minor areas of erodible soils in the northwest and southeast corners of the proposed project area. The grading plan and cut -and -fill -plan included in the Utility Report (Appendix J) show that the same deposit areas will be cut to accommodate development. Additional details of soil and engineering practices that may be required to address these features are discussed in the Preliminary Geotechnical Report and Preliminary Soils Assessment that have been included in this package of submittal materials (Appendix H and Appendix I). Best Management Practices (BMPs), such as appropriate grading and vegetation establishment will preclude erosion problems. and standard good operating procedures during construction will inhibit any nuisance dust problems. The proposed project site is in Seismic Hazard Zone 3 (Kalispell Uniform Building Code, 2007). All buildings will be designed to the appropriate seismic engineering standard for this area. Part I -- Section 4. Vegetation The site is located within the Intermountain Grassland Ecosystem, and has been impacted by agricultural development, including tilling. There are two main vegetation communities on the proposed proj ect site: the riparian corridor of the Stillwater River, and the tilled and irrigated fields. Figure 10 shows the vegetation communities currently present on the proposed project site. The majority of the site is tilled, irrigated fields, and is characterized by agricultural and non-native species. The area of vegetation in the riparian corridor of the Stillwater River is the only area in which some natural community is present, and even that riparian corridor reflects cleared natural communities and establishment of agricultural use on the flat areas; clearing and introduced species in steeper or riverine fringe wetland areas; and invasive weed throughout. There are two windrows of woody vegetation that in the northern portion of the site that were planted in the 1930's. Environmental Assessment Hyalite Environmental, LLP Glacier Town Center, Kalispell, Montana June 2007 The majority of the area of the proposed project site is cultivated fields. Wheat, alfalfa and hay grasses are planted, irrigated and harvested. There are no noxious weed species infestations in the agricultural fields. The riparian corridor is set off from the majority of the site by 25-foot (vertical) slope that rises from the floodplain surrounding the river to the terrace(s) and uplands that make up the majority of the site. Flat and gently sloping areas of the riparian corridor surrounding the Stillwater River have been used for agriculture at some time (cleared of woody and native species, sowed and harvested). The steeper and / or wetter (riverine fringe) areas in which agricultural machinery could not be used retain a more natural riparian scrub -shrub vegetation community. The agricultural portion of the riparian corridor surrounding the Stillwater River, on the relatively flat floodplain areas and more gentle slopes, is characterized by introduced species and grasses typical of the Intermountain Grassland Ecosystem. The distribution of vegetation indicates that at one time, the flat floodplain area was cleared and sown. Field work for this EA was performed in April, so that complete and rigorous identification of herbaceous species was not possible. The grasses appeared to be a mixture of reed canary grass with Idaho and rough fescue, smooth brome, western wheatgrass, and slender wheatgrass. It appears that this area has not been recently sown or harvested, and invasive and noxious weeds have become established throughout the grassy areas. Noxious weeds present in the riparian grassy areas include up to 10% cover, including: Canada thistle (Cirsium arvense), Houndstongue (Cynoglossum officinale), and minor tansy (Tanacetum vulgare). There may be additional noxious weed species present in the riparian corridor that were not obvious during the field investigation. The areas of the riparian corridor that are either too steep or too wet (riverine fringe) to work with agricultural equipment have not been cleared and are characterized by scrub -shrub riparian vegetation. The overstory is primarily comprised of alder (Alnus incana) and willows (Salix spp). The dominant scrub -shrub vegetation stratum is characterized by alder (Alnus incana), sandbar (and other) willow (Salix exigua), red -osier dogwood (Cornus sericea), wood's rose (Rosa woodsii), and serviceberry (Amelanchier canadensis). The herbaceous understory in the scrub -shrub community is extremely sparse, and is dominated by reed canary grass (Phalaris arundinacea) and smooth brome (Bromus inermis). There are wooded areas dominated by Ponderosa pine and Douglas fir on the slopes adjacent to the site, but not on site. At least a 200-foot wide buffer with no construction or structures will be maintained adjacent to the Stillwater River, as requested by MFWP (Mark Deleray, 2007, personal communication with Deb Rosa, CTA). A 75-foot riparian vegetation buffer will remain untouched adjacent to the Stillwater River. Existing wetland communities will be preserved. MFWP has noted that a pathway maybe made outside of the 75-foot riparian vegetation buffer but within the 200-foot wide structural set- back. There will be no impacts in the riparian corridor of the Stillwater River. Additional Environmental Assessment Hyalite Environmental, LLP Glacier Town Center, Kalispell, Montana June 2007 consideration may be given to a footbridge across the Stillwater River. All appropriate permits will be received prior to potential construction of a footbridge. The two windrows of mature trees and shrubs in the northern portion of the site will be protected and preserved, incorporated into the landscape design for the proposed development. There will be at least 72.3 acres of vegetated buffers, open space and park land. Landscaping will be designed to minimize water use, reduce fire threats, inhibit the establishment of noxious weeds and be conducive to appropriate wildlife -human interactions. For example, species attractive to large mammals (bears, deer, etc) will not be planted near traffic areas or in areas anticipated to be subj ect to frequent human use. The management agreements for both the residential and commercial areas will stipulate that landscaping must be irrigated, that noxious weeds must be controlled/eradicated, and that vegetation species used for landscaping will be those least susceptible to wildfire. The Stillwater River riparian corridor will be preserved, with appropriate vegetation and vegetation buffers, to provide wildlife cover and refuge. These concepts will be incorporated in the original landscape design and maintained through common area management documents and covenants (Appendices D and E). Management documents for the common areas and proposed park / open space will guide the selection of landscape grass, forb, shrub and tree species. Weeds will be managed throughout the development by weed control plans approved by the Flathead/Kalispell Weed Control Board, as stipulated in the management documents and covenants (Appendices D and E). Part I -- Section 5. Wildlife As discussed in Part 1— Section 4, there are two main different habitat (vegetation community) areas on the proposed proj ect site: the riparian corridor of the Stillwater River, and the tilled and irrigated fields. Within the agricultural area, there are two windrows that present refuge and a slightly different habitat in a subset of the agricultural area. Aerial photos from 2005 show approximately 140 acres of wheat field, 335 acres of alfalfa and hay, and 7 acres of floodplain sown grassland and riparian scrub/shrub. Figure 10 describes types of habitat and wildlife that are present upon or currently use the proposed project site, as well as the vegetation communities previously discussed. Figure 12 shows the location of wildlife habitat on the preliminary plat, and Figure 5 shows the location of delineated wetlands and waters of the US on the proposed project site. The wetland vegetation community is the only significant vegetation community and the riparian corridor is the only significant habitat within the proposed project site (Kalispell, 2003; Flathead Lakers 2002, 2004). All buildings will be outside of a 200-foot setback from the Stillwater River, providing protection for the riparian corridor. There will be a 75-foot vegetation buffer preserved at the edge of the river. The only potential land use within the 200-foot set back is for a trail or footpath. 10 Environmental Assessment Hyalite Environmental, LLP Glacier Town Center, Kalispell, Montana June 2007 The cultivated fields support small mammal and bird populations, and draw deer out of the riparian corridor. Because the majority of the fields are tilled, planted, irrigated and cut/harvested, there is episodic extreme disturbance that impacts species using the fields as habitat, so that the majority of wildlife use is by small mammals and birds. When the hay and wheat are high, deer bed down in the fields as well. The edges of the fields (along the windrow and external fence lines, road right of way) experience less extreme disturbance and likely serve as refuges for the small mammals and birds when the cultivated fields are being worked. The Stillwater River riparian corridor is an important wildlife corridor, serving as a migration pathway and refuge for wildlife. The riparian vegetation provides both refuge / cover and browse for a variety of birds, mammals, reptiles and amphibians. It is commonly used by white -tail deer, occasionally used by mule deer, and rarely used by black bear. Small mammals, including raccoons, skunks and foxes likely live in and use the corridor. The trees and shrubs provide habitat for numerous small bird species, and the river attracts water fowl. The Stillwater River is a low gradient water body through the reach adj acent to the parcel of interest, and has been ranked as a "substantial" fisheries resource by the MFWP. The site is approximately 1.87 river miles upstream from the confluence of the Whitefish River with the Stillwater River, and approximately 6.07 river miles upstream from the mouth of the Stillwater River at its confluence with the Flathead River (National Hydrologic Database distances, 2007). The full length of the Stillwater River, from its headwaters to the confluence with the Flathead River, is 19.058 miles (MT Fish, Wildlife and Parks distance, 2007). Species and species populations in the reach of the Stillwater River that is adjacent to the proposed development from the MFWP fisheries database (MFISH, 2007) are listed in Table 3. Table 3.

Montana Species of Concern The Montana Natural Heritage Program (MNHP) was contacted to determine the potential occurrence or use of the parcel by any Montana Species of Concern. The response form the MNHP is included in Appendix N of this package of submittal materials. The Flathead drainage is inhabited by Bull Trout that occupy Flathead Lake as adults and then migrate upstream to spawn in tributaries of the Middle and North Forks of the Flathead River. The headwaters of the Stillwater River and Whitefish River are important spawning waters for Flathead Lake Bull Trout (Salvelinus confluentus), and therefore the reaches of those two rivers in the vicinity of the proposed project are important migration waterways for Bull Trout. Bull Trout is a state S2 species, which is "At risk because of very limited and potentially declining numbers, extent and/or habitat, making it vulnerable to global extinction or extirpation in the state." The Bull Trout are a sensitive species that do not tolerate high sediment levels in their spawning streams. Because the Stillwater River is adjacent to the proposed project, there is potential for impacts to Bull Trout due to the proposed project. There is potential for construction -related activities to increase sedimentation to the stream. There is potential for long-term increase in runoff from an increased area of impervious surfaces. There is potential for increased direct human disturbance to the stream related to recreational use of the riparian corridor by potential residents of the proposed project. The proposed design minimizes or mitigates potential impacts by preserving the riparian corriodor, and using the approximate 7-acre parcel adjacent to the Stillwater River as park / open space. There will be no building or stormwater retention withn the first two -hundred feet from the Ordinary High Water Mark, as requested by MFWP (Mike Deleray, 2007, personal communication with Deb Rosa, CTA). A 75-foot riparian vegetation buffer will remain untouched, and pathways will remain outside this 75-foot buffer. The storm water runoff plan will ensure that no runoff reaches the stream without appropriate treatment. Low impact development alternatives such as bioretnetion cells, bioretnetion swales, and infiltrations basins may be implemented to mitigate surface -water runoff throughout the project area. In view of mitigation measures that are implemented in the proposed project design and property management documents, proj ect-related impacts "may affect, not likely to adversely affect" (USFWS impact category) the bull trout. 12 Environmental Assessment Hyalite Environmental, LLP Glacier Town Center, Kalispell, Montana June 2007 The parcel is within the potential range of the Long -billed Curlew (Numenious americanus), which is a state S213 species. The S213 ranking indicates that the breeding population (B modifier) of a species is "At risk because of very limited and potentially declining numbers, extent and/or habitat, making it vulnerable to global extinction or extirpation in the state." The Long -billed Curlew nests on relatively dry grasslands and winters in marshes and fields, lawns and beaches (Sibley, 2003). The Long -billed Curlew breeds widely throughout the state, although it is more common east of the Rocky Mountains. Long -billed Curlews prefer short grass habitat, commonly native prairies, but occasionally use grazed mixed -grass communities (MF", 2005; MT Steering Committee Intermountain West Joint Venture, 2005; Jones and others, 2003). Although there is potential for Long -billed Curlews to use the proposed project site, it is unlikely to be used for breeding habitat because of the extreme disturbance related to crop cultivation and grazing on the agricultural fields within the proposed project site. Therefore, the proposed project will not impact Long -billed Curlew. Federally Listed Threatened and Endangered Species The MDT evaluation of the Highway 93 corridor and recent re-evaluation of potential environmental impacts of the proposed Kalispell Bypass (MDT, 1994 and 2005) found the potential occurrence for two federally listed threatened and endangered species in the vicinity of the proposed project: the American Bald Eagle (Haliaeetus leucocephalus) and Bull Trout (Salvelinus confluentus). Additional lists for Flathead County and literature reviews found that there is potential for Canada lynx (Lynx canadensis), gray wolf (Canis lupus), and grizzly bear (Ursos arctos horribilis) to potentially occur in the vicinity of the proposed project site as well. The greater Kalispell area supports the highest density of nesting Bald Eagles in Montana. There are no Bald Eagle nests within or in the near vicinty of the proposed project (2.5- to 3.5-mile MNHP search radius). The proposed project does not lie within the primary use areas for any known Bald Eagles. Bald Eagles are known to winter in the Kalispell vicinity, feeding primarily on fish, waterfowl and carrion. Migrating Bald Eagles are also likely to use the Kalispell vicinity during travel between summer and winter ranges. Due to the distance of the proposed project site from any nest site, the proposed project is not expected to substantively disturb any Bald Eagle activity. Abundant undisturbed, significantly better alternative habitat exists in the vicinity of Kalispell. Vegetation in the riparian corridor will be preserved. There will be no impacts to Bald Eagles due to the proposed project. The Bull Trout was previously discussed as a Montana Species of Concern. US Fish and Wildlife Service (USFWS) will be consulted in order to assure that potential impacts to Bull Trout are avoided or minimized. 13 Environmental Assessment Hyalite Environmental, LLP Glacier Town Center, Kalispell, Montana June 2007 Canada lynx, gray wolf, and grizzly bear are threatened species that also occur in northwestern Montana. However, due to the location of this proj ect within an urbanized area and the general lack of suitable habitat for these species, it is unlikely that any of these species would occur near the proposed project. For these reasons, any potential effects to these species would be negligible. The proposed project would have no effect to Canada lynx, gray wolf, or grizzly bear. Part I -- Section 6. History of the Site and Land Use The historic center of the City of Kalispell, the intersection of the railroad with Main Street, is approximately 2.8 miles south of the Glacier Town Center site. However, the City has grown considerably, and the outermost city boundaries now extend 4.9 miles south and 2.0 miles north of the proposed project site. The proposed project site is not currently annexed into the City of Kalispell. Development in Kalispell has occurred around the highway corridor with recent commercial expansion of business that require larger undeveloped parcels" (Kalispell, 2003; 2007). Highway 93 North is the major transportation corridor between Kalispell and Whitefish. The proposed project site has been in agricultural use since early settlement of the region. Both published and oral resources indicate that it is unlikely that there has ever been any use of the Glacier Town Center parcels except for farming and ranching since displacement of Native Americans (Elwood, 1980; Van West, 1986; Spritzer, 1999; McKay, 2000). Deed and Chain of Title research was performed by reviewing the chain of title for each of the Glacier Town Center parcels in the plat book of the Flathead County Clerk and Recorder (Hyalite Environmental, LLP, 2007). The land records for the parcels of interest were tracked and reviewed to the point at which the deed trail could no longer be tracked without extensive research, due to record -keeping methods that are not conducive to investigation (non -indexed deeds) or due to record complexity such as parcels sold at sheriff's sale following a foreclosure. Where possible, the chain of title was taken back to original patent. There is no evidence in the recorded documents for the subject site of historic use for any purpose other than agricultural. There are no known or recorded archeological, paleontological, historical or cultural sites on or in the near vicinity of the proposed project. A cultural resource file search was conducted by the MT State Historic Preservation Office (SHPO). SHPO records showed that there are no previously recorded sites eligible National Register of Historic Places listing nor have there been any cultural resources inventories performed in the immediate vicinity of the proposed project site. Correspondence from SHPO is included in Appendix N. 14 Environmental Assessment Hyalite Environmental, LLP Glacier Town Center, Kalispell, Montana June 2007 The proposed project site is currently in agricultural use (wheat, alfalfa), and is considered to be "prime farmland if irrigated." Conversion of the land to commercial and residential, open space / park and other mixed uses will remove the area from agricultural production. The vicinity of the proposed project is included in the Kalispell Growth Policy (2003, as amended through May 2007). On the current growth policy map for the vicinity of the proposed project, the parcels of the proposed project site have been planned as "Mixed Use." It is anticipated that the project will be annexed to the city. Adjacent land uses are widely mixed. The Stillwater River riparian corridor, high -voltage power line easement, and the cemetery lands adjacent to the proposed project site are intended as "greenbelt." Areas west, northwest and northeast of the site are designated as suburban residential, whereas the lands to the southwest is commercial (Loew's, Target, Costco), to the southeast is industrial (Semi -Tool), and to the east and direct south is urban residential. A traffic study has been carried out to determine the likely needs and impacts of the proposed development, and is included in this package of submittal materials as Appendix L. Four full - movement access drives will be built for the build -out of the Glacier Town Center. Additional proposed access to the development will include a full -movement access on Whitefish Stage Road, and additional access drives along Rose Crossing Road between US Highway 93 and Whitefish Stage Road. The traffic impact study includes counts of current traffic, projections of traffic without the proposed development, projections of traffic with the proposed development, and recommendations for mitigation / accommodation of increased traffic. According to the "Kalispell 2006 Construction, Subdivision and Annexation Report" (Kalispell, 2007), there were 349 new housing starts in 2006, down by 7.7 percent from 2005 and 27.3 percent from 2004. City planners interpret this trend to indicate that "demand for single family housing continues strong" and that there is "an increasing market for townhouses and multi -family units." The majority of the new housing construction is occurring in recent subdivisions, located north and northwest of the city. In 2004 through 2006, major commercial construction activity occurred in the northern city along Highway 93, southwest of the proposed project site. Commercial projects in the vicinity of the new project have included Home Depot, Target, Borders Books, Pier One Imports, Petco, Lowe's, Costco, and IHOP, Starbucks, Wells Fargo Bank, and hotel(s). A new fire station has been built n the vicinity of the proposed project, and the new Glacier High School is being built just a little over one mile west of the proposed project site. The growth plan, census documents and commercial trends for the area north of Kalispell indicate the ongoing need for new housing of different types, new office and professional space and new 15 Environmental Assessment Hyalite Environmental, LLP Glacier Town Center, Kalispell, Montana June 2007 commercial retail space. However, while the surrounding development is evidence of need for these services, the diverse mix of uses in thoughtful coordination as presented in this proposed project is unique. The residential community would be anchored by a Community Center and parklands. The adjacent retail services will have a stable core in the Lifestyle Center, which benefits from Wolford Development's experience in creating successful retail centers and the preliminary commitments of several prime retail tenants. The juxtaposition of different professional and commercial spaces with the residential areas and Lifestyle Center offer a potential for reduced car travel and pedestrian life styles. The Glacier Lifestyle Center is an outdoor and pedestrian -friendly shopping district with anchor stores that provide an impetus for continued adjacent development by others. Currently, residents of the Flathead Valley must travel to Spokane for comparable retail exposure. There is currently an easement for high -voltage power lines across the proposed project site. The existing high -voltage power lines will remain, and will be the only anticipated health or safety hazard on the site. There is no anticipation of the future mixed -uses at the site creating a nuisance. 16 Environmental Assessment Hyalite Environmental, LLP Glacier Town Center, Kalispell, Montana June 2007 Part II — Summary of Probable Impacts The proposed use and number of lots or spaced of each type of residential and commercial unit are listed on Table 1 and shown on Figure 3. Part II -- Section 1. Effects on Agriculture There are 2.65 acres of"Farmland of State -Wide Importance" (MRCS, 2007) within the 485 acres of the proposed Glacier Town Center site (0.5%). That area is shown on Figure 10. However, 337 acres of the site are "Prime Farmland If Irrigated" (MRCS, 2007). 471 Acres of the 485-acre site (97.5%) of the land has been in agriculture recently (hay and wheat). All of this land would be removed from agricultural production. Agricultural land south, west and north of the Glacier Town Center site has already been considered or is currently being considered for development. However, it is likely that portions of the land surrounding the Semitool facility will remain as an agricultural buffer between Semitool and adjacent properties, so that the southeastern portion of the site may remain adjacent to agricultural land. The land is owned by the Chief Executive Officer of the Semitool, and the farm manager for the land does not know of any plans that the owner has except to keep the land in hay production in the near future (Hyalite Environmental, LLP, 2007). There are advisements and stipulations in the management documents to limit any nuisance problems that may arise from the adjacency of the Glacier Town Center and these hay fields. It is likely that in the long term, the value of the lands for development will strongly outpace the value of the adjacent lands if they were to remain in agricultural use. The Kalispell Growth Policy 2020 (2003) projects that most of the land north of Kalispell along Highway 93 in the vicinity of the Glacier Town Center will be developed. Part II -- Section 2. Effects on Agricultural Water User Facilities Discussions with adjacent landowners have shown that the only land adjacent to the proposed proj ect that will remain in agricultural use (for at least the near future) are the hayfields surrounding the Semitool facility on the southestern boundary of the site. As mentioned above, there are stiuplations, advisements and mechanisms for complaint set up in the management documents to avoid and mitigate any potential conflicts with agricultural use. 17 Environmental Assessment Hyalite Environmental, LLP Glacier Town Center, Kalispell, Montana June 2007 The Semitool fields that are in agricultural use do not have any agricultural water user facilities that cross the proposed project site. Currently, surface water rights for the Glacier Town Center parcels are taken from the Stillwater River, pumped to the site via underground pipelines and distributed on the fields via a wheel -line irrigation system. These water rights will most likely no longer be used for irrigation. No agricultural water user facilities will remain on the Glacier Town Center site. There will be no increase of vandalism to agricultural water user facilities and no possible nuisance problems with regard to agricultural wateruser facilities associated with this proposed development. Part II -- Section 3. Effects on Local Services Table 1, Anticipated Distribution of Development Types, indicates the proposed use and number of lots or spaces for each type of development. The exact development of the later phases is not definite at this point. Details will be finalized and described on materials submitted for permitting of those phases. It is anticipated that the project will spur an additional cost for services such as roads, bridges law enforcement, parks and recreation, fire protection etc. Historically and nationwide studies from organizations such as the Brookings Institution and American Farmland Trust have shown that residential construction below a certain amount of household price and density is a burden for a community. However, commercial and industrial development generally have an immediate net gain for a community and even -out over a 30-50 year period. The combination of commercial and residential facilities in a multi -use development such as that proposed for the Glacier Town Center mitigates the community impact of needed residential development with associated commercial development. Agriculture and open space have long term net gains for communities because the services required are much less. The project will design and incorporate safe intersections, pedestrian walkways and roadways. The developer will install and pay all costs for installation of roads within the commercial area and the residential neighborhoods. The commercial center will retain ownership and maintenance responsibility for the roads in that area. The roads in the residential areas will be owned and maintained by the City of Kalispell. The developer is working with the Montana Department of Transportation (MDT) to determine what upgrades will be needed to the roads adjacent to the proposed project. The proposed project has been designed to support a pedestrian or bike lifestyle, reducing automobile use of the community. This project attempts to have a mixture of land use types. The significant open spaces within the project area net benefit to the community. The developer is gifting a sizeable amount of land to the parks and recreation department as well as capitol improvements for the park system. It is anticipated that these gifts would include a 25-acre park and 5 acres to be used for a community 18 Environmental Assessment Hyalite Environmental, LLP Glacier Town Center, Kalispell, Montana June 2007 center. Ongoing maintenance costs could be applied to property taxes or even impact fees currently under review by the City. The impacts to the sewer system are anticipated to be born completely by the users of the sewer system and is a pay-as-you-go cost as users hook up to the system. It should be noted that another developer is extending water and sanitary sewer along Highway 93 that the Town Center is anticipated to use. This Glacier Town Center intends to drill at least one well for the project within the later (third or fourth) construction phase. This will be used to provide pressure to the entire system. It is anticipated that the cost will born by the developer. A new fire station is contemplated within 3 years located in the Silverbrook subdivision north of the project. The tax revenue of this commercial project will help pay for this new station's capitol and manpower costs projected for this new station. This project will ultimately impact the school system at full build -out. Because there is such a large commercial component the impacts are significantly less than other developments in the area. Typically there are 0.5 to 0.75 children per household in Flathead County. If there are approximately 550 residential units planned over the course of the ten-year build -out, it is likely that the project will cause an increase of 275 to 412 children to the school district in the next ten years. It is anticipated that the city may need to hire additional police to patrol this 485 acre development at full build -out. Recent projects in the northern Kalispell Highway 93 area have cited that 1.8 officers are needed for every 1,000 residents. Using the current anticipated development unit types shown on Table 1, and the average household size of 2.5 people per household, the proposed project will include 1,655 new residents through buildout, potentially requiring three new officers. Based upon 2006 salary for a police office with one year of experience, three officers would cost approximately $161,000 per year (2006 dollars). It is anticipated that the proposed project will generate tax revenues that will pay for the support of needed services, and will financially support the extension of services that are currently needed . The proposed project is anticipated to create j obs and bring revenues into Kalispell from throughout Flathead County and northwestern Montana. The proposed proj ect will significantly increase value - related property taxes for the parcels within the Glacier Town Center, and likely some adjacent areas as well. This project is not expected to negatively impact any current mill levies or bond ratings. The valuation of the property values due the commercial nature of this project could have a positive impact on the City's bond rating. As mentioned above, the project relies on the private extension of water and sewer along Highway 19 Environmental Assessment Hyalite Environmental, LLP Glacier Town Center, Kalispell, Montana June 2007 93. These costs will be initially born by another, separate developer. However, the Glacier Town Center developer anticipates providing added payments for the right to tap onto the system. It is anticipated that the development will need to use separate sewer alignment for later phases of the project (fourth and subsequent phases). These would follow Whitefish Stage Road and would likely be born by private development similar to the Highway 93 corridor plan. The assessed value of the parcels included in the Glacier Town Center project is currently $561,482 (2003 full reappraisal value, MT DOA, 2007). The anticipated value of the proj ect at build -out (full, not assessed tax value) is $750 to $800 million. The 2006 tax revenues generated from the parcels included in the proposed proj ect was: $83 5 county, $2,445 education, and $74 other (Soil and Water Conservation and West Valley Fire), or $3,354 in property taxes. In 2006 dollars, tax rates and approximated taxable values, the amount of taxes that the proposed proj ect would have paid in 2006 would have been (approximately): $33,800 county, $98,900 education, $3,000 other, for a total of $135,700 in property taxes. [Note: amounts are a rough estimate based upon rates from the Flathead County Tax Department.] The parcels, developed as proposed, will provide approximately forty times the tax revenues of the current land use of the parcels. Currently, impact fees for transportation, fire, police and parks are being contemplated in Kalispell. Over the long haul, a conservative estimate of construction is about 1.5 million square feet of commercial, 250,000 square feet of office space and 500 residential lots of varying sizes and costs. If you apply a $225/square foot cost for the land and building cost for commercial and office, one gets $350 million in construction costs and improvements. Assuming a residential valuation to the project at $350,000 average price of a home, the total construction improvement is $150 million for the residential components at final build -out. It is proj ected that new real estate taxes would cover the costs of improvements to the system. There are no special improvement districts contemplated as a part of the project. Part II -- Section 4. Effects on the Historic or Natural Environment As discussed in Part I -- Section 6, there are no cultural resources on the proposed project site or adjacent properties that will be impacted by the proposed project. As discussed in Part I -- Section 1, there will be no impacts to any natural stream bank. The development will be served by public water and sewage, so that there will be no private septic systems potentially impacting 20 Environmental Assessment Hyalite Environmental, LLP Glacier Town Center, Kalispell, Montana June 2007 surface water or ground water. There will be no depletion of groundwater in the deep alluvial aquifer on site since the development will be hooked up to City of Kalispell public water supplies. There would be some use of ground water from the deep alluvial aquifer during later phases of the development, when it is likely that a ground water well will be used as an additional source of water and water pressure to the city water lines. As discussed in Part I -- Section 2, there will be minor depletion of the discontinuous, shallow ground water aquifer located in sixty acres of the northwest portion of the site, since this aquifer is recharged primarily by ponded snowmelt, which would be limited by development. However, as noted previously, this is a small, discontinuous and seasonally fluctuating shallow ground water source that is not appropriate for domestic or irrigation water supply because of low yield and poor water quality. There is additional information concerning ground water in Appendix G, the Hydrology Report. The project will be designed and built in compliance with Montana Department of Environmental Quality and City of Kalispell requirements for minimization and mitigation of storm water runoff from hardscapes, so that the runoff volume from the development site will be no greater than the runoff from the site pre -development for a 10-year, 6-hour storm event. Storm water runoff will be captured and treated in low impact development alternatives such as bioretention cells, bioretention swales and infiltration basins in conjunction with acceptable traditional storm water treatemetn and disposal methodsc. Catch basins will include baffles to collect debris and provide oil/water separation to improve the efficiency of the infiltration system. Additional information concerning surface water runoff drainage and storm water controls are included in Appendix K, the Storm Water Report. Culverts and stormwater conveyances will be sized to accommodate the flows that will result from the design storm /rain events. Grading required for development and the construction of roads will not create any increased potential for erosion. There will be no contamination of soils by sewage treatment systems since the development will be hooked up to City of Kalispell sewage treatment system. Although unvegetated soils may be exposed during construction, there will be appropriate construction standard operating procedures, dust control and Best Management Practices to minimize any potential erosion from the unvegetated soils. After construction and the installation of landscaping, there is likely to be much less potential for soil erosion on the developed project site than in the agricultural fields that were previously harvested, tilled and sowed annually. Part II -- Section 5. Effects on Wildlife and Wildlife Habitat As described in Part I -- Section 5, 471 of the 485 acres of the Glacier Town Center site are currently very limited wildlife habitat due to the episodic extreme disturbance of tilling, sowing, cultivating and harvesting hay and wheat. Although the development will significantly increase 21 Environmental Assessment Hyalite Environmental, LLP Glacier Town Center, Kalispell, Montana June 2007 human activity on the site, it will simultaneously significantly expand and improve available wildlife habitat. As shown on Figure 3, approximately 72.3 acres, 69 of which are currently agricultural land, will be converted to open space / park with native species landscaping. There will be an increase in diversity of habitat type due to incorporation of forbs, shrubs and trees throughout the development. Fifteen hundred linear feet of the Stillwater River streambank and riparian corridor will be preserved and protected. It is anticipated that the property management documents will promulgate regulations and restrictions for residential property owners' and tenants' pets. Dogs will be required to be leashed or under control at all times. Cats are likely to have an impact on the small mammal and small bird populations that will colonize the new habitat that will be created by the project landscaping in vegetated buffers and open space. It is probable that there will be an overall balance of negative and positive impacts on wildlife and wildlife habitat at the site, with the net change primarily a shift in habitat type and the species using the site. Part II -- Section 6. Effects on Public Health and Safety The Glacier Town Center development will have a positive impact on public health and safety by creating a development which uses City of Kalispell water and sewer, has a well designed, low impact surface water and storm water drainage system.. There are two primary health and safety hazards adjacent to / on the proposed project site. These include the high -capacity power line corridor/easement and the natural hazards presented by the Stillwater River. The high -capacity powerline hazard will be mitigated by strict regulation of land uses and actions in the adjacent areas. Analogously, the hazard presented by the Stillwater River will be mitigated by preservation of a 200-foot set back from the river to any buildings or structures. Any trails or parks within the proposed project will be designed, constructed, and maintained to comply with all applicable regulations, which will further mitigate any potential risk to human health or the environment. Land use adjacent to the proposed project development includes agricultural, residential, industrial and commercial areas. It is likely that the increased value of the property in the vicinity of the Glacier Town Center will make the residential and commercial uses of adjacent lands more prevalent. Adjacent agricultural lands are likely to be developed, and the industrial sites (such as Sonju Industries, Hyalite Environmental, LLP, 2007) will be more likely to move to more compatible locations rather than expand their facilities at their present sites. 22 Environmental Assessment Hyalite Environmental, LLP Glacier Town Center, Kalispell, Montana June 2007 Part III -- Community Impact Part III -- Section 1. Education and Busing Students living in the Glacier Town Center development would attend Edgerton Elementary School, Kalispell Junior High School and Flathead High School. Parents may apply for their children to attend an elementary school other than Edgerton, the neighborhood Elementary School, but acceptance of transfer is dependent upon available space. The residential plan for the Glacier Town Center development includes 662 residential units. The average household in Kalispell is 2.21 people, and 30.6% of the households in Kalispell (2000 Census) have children under eighteen. This suggests that the residential portions of the Glacier Town Center will be homes to approximately 203 students. Alternatively, if the demographic data for the county is used, the average number of children per household for Flathead County is 0.5 to 0.75. The Flathead County demographics would suggest that the Glacier Town Center will be homes to as many as 497 students. If the ages of these students is distributed evenly, this would be 62 to 153 students in grades 9-12 (Flathead High School District No. 5), and 141 to 344 students in grades K-8 (Kalispell Elementary School District No. 5). This would be a 2.4% to 6.0% increase in the high school student body and a 5.7% to 14.0% increase in the elementary school student body. Using the 2006-2007 budget for the school district, this would increase costs from $982,000 to $1,026,000 in entitlements, and $70,000 to $170,000 in transportation (busing) costs (School District No. 5 and Flathead High School District, 2006). The new high school facility has been designed to accommodate projected growth. Edgerton Elementary School, on the other hand, is currently at or above design capacity. The impact of the Glacier Town Center development to the elementary school is likely to require expansion of elementary facilities. Part III -- Section 2. Roads and Maintenance The Glacier Town Center is anticipated to create more traffic along US Highway 93, West Reserve Drive, and Whitefish Stage Road. The development team is currently working with MDT to coordinate the project with improvements to the roads, intersections, signals, and signage on roadways bounding the project site. 23 Environmental Assessment Hyalite Environmental, LLP Glacier Town Center, Kalispell, Montana June 2007 It is anticipated that all internal project roads will be constructed by the developer. Following construction, the roads within the Glacier Lifestyle Center will be owned and maintained by the Glacier Lifestyle Center. All roads outside of the Glacier Lifestyle Center are to be owned and maintained by the City of Kalispell. All roads will be constructed to comply with City of Kalispell standards, and the relaxations requested within this application, should they be approved. It is anticipated that the project developer would mitigate impacts to the adjacent roads. The Traffic Impact Report (Appendix L) provides further information concerning likely roadway needs. Part III -- Section 3. Water, Sewage and Solid Waste Facilities The site will be supplied with drinking water and wastewater treatment by the City of Kalispell. City utilities are being extended along Highway 93 beyond the Glacier Town Center site in the summer of 2007. The specific needs and plans for water and sewage lines, and facilities within the proposed development are presented in the Utility Report (Appendix J). The development team is working with Kalispell Public Works personnel who have assured the developer that the City has adequate capacity to service the project. All utility facilities will be designed and constructed to meet or exceed the requirements of the City of Kalispell Standards for Design and Construction and Montana Department of Environmental Quality Circulars 1 and 2. The Utility Report (Appendix J) concludes that utility demand for Phase 1 can be met with the infrastructure that will be in place at the time of development. Phase 2 can also be supported by this infrastructure; however, the system would function better if another supply source was added. Phases 3 through 5 will require additional infrastructure, however, they are not scheduled to be developed until 2014-2020. Each phase will need to be reanalyzed prior to development The Flathead County Solid Waste Landfill is managed by the Flathead County Solid Waste District (SWD). The landfill has recently expanded its capacity and capabilities. The facility is a licensed Type 11, III and IV facility and is projected to be sufficient for county needs for thirty to sixty years, based upon Flathead County's projected growth rate (Flathead County SWD, 2006). The Glacier Town Center design team has contacted Dave Prunty, the Director of the Flathead County SWD, and a copy of correspondence dated May 21, 2007, is included in Appendix N. Additional guidelines and restrictions concerning trash are included in the property management documents. For example, all commercial buildings will provide at least one enclosed, screened trash duinpster per building. All trash dumpsters shall be screened from view by durable enclosures, and shall be animal proof. Trash will be emptied on a regular basis to insure sufficient room to store trash at the end of each working day. Residential trash containers will be those approved by the contracted trash collector and will be stored in a garage or shed. 24 Environmental Assessment Hyalite Environmental, LLP Glacier Town Center, Kalispell, Montana June 2007 Part III -- Section 4. Fire and Police Protection The Glacier Town Center development will be under the jurisdiction of the Kalispell Fire Department. All structures within the development will be built to meet or exceed the protectiveness of the Fire Protection Requirements of the Kalispell Fire Department, as enumerated in a letter from DC Haas, Assistant Fire Chief/Prevention, to CTA Architects Engineers, dated May 24, 2007. This letter is included in Appendix N of these submittal materials. Previous discussions with the Fire Department have pointed out that new development will primarily impact personnel, requiring that additional staff be hired. There will be some need for new facilities and equipment to expand the capabilities of the fire department to cover the proposed development. It is anticipated that tax revenues generated by the proposed development will cover these costs. City water supplies will be available for fire fighting at the Glacier Town Center. Fire hydrants connected to city water will be available throughout the development. It is anticipated that an additional well will be needed to provide additional pressure to the system in later phases of development. The developer is currently working with the Kalispell Police Department to discuss law enforcement concerns. As discussed previously in Section II Part 3, it is anticipated that at full buildout, the proposed proj ect may require 3 additional police officers. The costs of the additional police officers are anticipated to be paid through the increase in tax revenues that will be provided by the development. Ambulance service will be provided by the City of Kalispell Fire Department. Emergency medical services will be provided by the Kalispell Regional Medical Center, which is located 3 miles from the project site. Part III -- Section 5. Parks and Recreation Facilities An Open Space map is included as Exhibit K, and Parks Plan is included as Exhibit L. The prof ect will have a main central park of approximately 25 acres. Amenities are anticipated to include a pond, tennis courts playground, walking trails etc. The capital improvements will be phased in and it is anticipated that the costs born by the developer. Perimeter linear parks that include trails, benches and trash receptacles will be constructed and dedicated by the developer. It is anticipated that parks will be dedicated to the City of Kalispell and maintained by the City through taxpayer funds. It should be noted that the developer has agreed to donate a five -acre parcel 25 Environmental Assessment Hyalite Environmental, LLP Glacier Town Center, Kalispell, Montana June 2007 of land for a new community center. Part III -- Section 6. Payment for Extension of Capital Facilities It is anticipated that the developer will pay for water and sanitary sewer on Hwy 93. In addition, the first phase preliminary plat includes the construction of Rose Crossing to provide an ease - west connection between Hwy 93 and Whitefish Stage Road. 26 Environmental Assessment Hyalite Environmental, LLP Glacier Town Center, Kalispell, Montana June 2007 Signatures Date Wolford Development, LLC 26 West 6th Ave. Helena, MT 59624 Date CTA Architects Engineers #2 Main Street, Suite 205 Kalispell, MT 59901 Date Hyalite Environmental, LLP PO BOX 90 Gallatin Gateway, MT 59730 27 Environmental Assessment Hyalite Environmental, LLP Glacier Town Center, Kalispell, Montana June 2007 References Cited CARES, 2006.
