Noxious weeds must be controlled in all developments as directed by the county weed control district (district) in accordance with the Montana County Noxious Weed Control Act (MCA 7-22-21). The developer must have any noxious weeds identified and their location mapped by a person with experience in weed management and knowledgeable in weed identification. A noxious weed management and revegetation plan approved by the district for control of noxious weeds must be submitted with the preliminary plat application.

Letter to City of Bozeman Re: Park View Crossings- Preliminary Plat Lot 4 of Minor Subdivision 400, Bozeman, MT June 21, 2021 Page 4 of 6 L:\193211\_Preliminary Plat\_Response\_Part II\_Cover Letter CoB- Preliminary Plat.doc Sec. 38.220.060. Additional subdivision preliminary plat supplements A. The following list of preliminary plat application supplements must also be provided for all subdivisions unless waived by the development review committee during the pre-application process. The developer must include documentation of any waivers granted by the city after the pre-application meeting or plan review. Additional relevant and reasonable information may be required to adequately assess whether the propose subdivision complies with this chapter and the Montana Subdivision and Platting Act. The need for additional information is determined during the pre-application process. 1. Surface water A small section of the Spring Ditch is located near the northern property boundary and encroaches into the northern portion of the stormwater easement. The original source of the Spring Ditch was apparently a natural spring located south of what is now the regional park. Currently the water is collected underground (reportedly via a French drain system under Oak Street) and discharged to a pipe located in the bottom of the man-made channel. The channel then flows north and crosses Baxter Lane. An existing irrigation easement (Doc. #2081799) is also located within the regional park. The existing wetlands located along Spring Ditch are shown on the Preliminary Plat. The Spring Ditch or any associated wetlands will not be altered in any way with the construction of this development. 2. Floodplains There does not appear to be any portions of the subdivision in proximity to a watercourse draining an area of twenty-five square miles or more. The portion of the Spring Ditch’s 100-year floodplain is only located within the Common Area lot for the stormwater detention pond. 3. Groundwater Groundwater is known to be high in this area. A geotechnical report was done in 2001 that included borings near the existing Pond 5B location. This boring showed depth to groundwater at 3 feet below ground surface. The Gallatin County Local Water Quality District Monitoring Well in the regional park (directly south of the development) shows the static water level at 6 feet. We have noticed a late peak in some of the groundwater monitoring around town, showing up in or near September. I am confident this suffices for the applicable groundwater elevation and we have provided sufficient storm storage and are not altering the existing pond bottom elevation. 4. Geology; soils; slopes Geology and soils will likely be similar to those encountered during the construction of Phases 4G & 4H of the Crossing 2 at Baxter Meadows. There are no known geologic hazards associated with this property other than the regional designation of Seismic Zone 3. Conformance to relevant building codes can mitigate this degree of potential hazard. No unusual construction techniques are required due to geology, slopes, or soil types other than appropriate seismic design standards common throughout the Gallatin Valley. Significant slopes are not anticipated. The NRCS soils report is included with this submittal. Wetlands near Spring Ditch have been delineated and are shown on the Preliminary Plat. 5. Vegetation The property has been vacant and has not been used agriculturally in the past. The property is adjacent to the Gallatin County Regional Park to the west and residential development on all other sides. No known critical plant communities have been located. After development, the majority of vegetation will be lawn, shrubs, and boulevard trees typical of residential subdivisions.

Wildlife No animals listed under the “Animal Species of Special Concern”, (Montana Natural Heritage Program, Helena, 2003) have been observed or are known to occupy the property. Habitat most suitable for wildlife includes the area around the Spring Ditch that will not be developed. 7. Historical features Damon Murdo, Cultural Records Manager of the Montana Historical Society, has not noted any previously designated cultural properties in the area. 8. Agriculture Due to the development in the area, no agricultural practices have been performed on the property for several years. 9. Agricultural water user facilities The Spring Ditch agricultural facility will continue to flow and the existing irrigation easement located completely within the regional park will not be abandoned or altered with this project. 10. Water and Sewer See Section 4 for the Engineering Report (water, sewer, storm) and Section 5 for the Engineering Plans. Water and wastewater system improvements will be designed to meet City of Bozeman Standards. 11. Stormwater management See Section 4 for the Engineering Report (water, sewer, storm). Stormwater improvements will be designed to meet City of Bozeman Standards. 12. Street, roads and alleys A single “loop” road will be required to serve the subdivision as shown on the Preliminary Plat. The road will consist of a continuation of Tschache Road from the intersection with Vaquero Parkway, as well as an additional T intersection with Vaquero Parkway. Road A has the following characteristics: - 60-foot right-of-way - 33 feet from back of curb to back of curb - Standard City of Bozeman curb and applicable curb returns The privately maintained alley has the following characteristics: - 30-foot public access easement - 16-foot paved width - inverse crown (without curb and gutter) 13. Utilities The subdivision plat has been submitted to Northwestern Energy. A 10-foot utility easement has been provided along all street frontages. 14. Educational facilities. The Bozeman School District indicated its facilities and bus system would be able to handle the additional students created with this development.

Land use The proposed development will consist of: - 44 single family lots - (9) 4-plex units - (2) 3-plex units - (1) 2-plex unit 16. Parks and recreation facilities Parkland requirements are being met with a combination of cash-in-lieu and trail corridor improvements for the regional park. See Section 8.o for the cash-in-lieu of parkland dedication. 17. Neighborhood center plan This development does not contain a neighborhood center, as it is directly adjacent to the Gallatin County Regional Park including the Dinosaur Playground. 18. Lighting plan Please see Section 6 for the lighting plan. A total of three light fixtures are proposed with this development. 19. Miscellaneous This development will not affect any public land access. Access to public lands including the Regional and Dinosaur Park currently exist on Oak Street and at the Bozeman’s Firehouse #3. The developer is proposing to install a 10-foot paved trail on the western side of Vaquero Parkway to provide trail/park connectivity for the community. 20. Affordable housing Affordable housing is no longer a requirement, per House Bill 259 signed into law earlier this year that removed the inclusionary zoning component.
