The intent of the site plan is to create a “pad-ready” site that is more favorable for potential buyers/developers, while still incorporating the wetland impacts as well as the stormwater components. An MDT approach will be constructed provide access to the lot for the future development. The exact use of the proposed building is not yet known, though the approach will be designed to meet the demands of an office-use development and will accommodate a WB-40 intermediate semi-trailer. A 24” CMP culvert will be installed under the approach for stormwater conveyance down the existing roadside ditch. An MDT approach permit has been applied for as well, to coincide with this application, but no official determination from MDT has been received as of the date of this letter. Concept Review Comments: The following are responses to City staff comments dated September 30, 2019 during the Concept Review phase of this project. Planning: 1. See attached site plan application for the property within M-1 zoning. 2. There will be no architectural design submitted with this application. The use of the proposed building is not yet known. The preliminary site design and landscape drawings are attached with this submittal. 3. Crosswalks will be installed when the site is paved. 4. The exact location of the trash enclosure and utility meters are not yet known as those will be developed with the final site plan application. 5. As stated above, the use of the building is unknown and architectural drawings have not been created yet. 6. Parking lot and street frontage landscaping are detailed in the attached landscape drawings. Details are provided in the civil drawings showing the proposed detention pond cross section, as well as the typical cross section for the biofiltration swales. 7. A photometric plan will not be provided at this time, as the parking/building area will only be built up with gravel to provide a potential buyer a “pad-ready” site. 8. A wetland delineation map has been included with this submittal. The map illustrates the entire wetland area and the wetland area that will be impacted with the construction of the pad-ready site. Letter to City of Bozeman Re: East Frontage Road – Site Plan Application Bozeman, MT October 14, 2020 Page 2 of 4 L:\193190\_Site Plan Application\City Cover Letter.doc Engineering: 1. All wetland information/mapping is included with this submittal, see the ‘5.0_Wetland & Watercourse Adherence’ document. 2. The wetland delineation map, report & City municode referenced responses are provided with this application. 3. The median striping on the Frontage Road restricts us from moving the proposed approach any further west. Coordination with MDT is still on-going as to where the final approach location will be, so once more is known on the MDT side of things, final approach approval/deviation with the City will be supplied. 4. The geotechnical report is included, showing the in-situ soils on site as well as the depth to groundwater. We have also been monitoring the groundwater levels on-site using the 6 monitoring wells on site installed with the geotechnical borings, see the also included groundwater monitoring data. No underground stormwater facilities are anticipated. 5. As the building use is not yet known, an accurate sewer demand rate cannot be estimated. Therefore, at this time, a sewer service will not be constructed but will be accounted for with any future site plan submittal. 6. The sewer main on the east side of the lot is within the property boundary. A 20’ utility easement was granted for the construction of the sewer main, see the as-built plans of SID 615. 7. Curb and gutter will be installed around the parking lot perimeter, once a final site plan layout is developed. 8. Estimated peak hour traffic demands are not included with this application, due to a use/land plan not being known at this time. Once a use is determined, those numbers will be submitted with the future site plan application to determine if a TIS is necessary. Project Narrative: 1. General Information 1.1 Project Owner/Developer The existing property is owned by Frontage Road LLC. Owner contact information is below: Frontage Road LLC PO Box 1070 Bozeman, MT 59771 Project Team: Civil Hyalite Engineers 2304 N. 7th Avenue, Suite L Bozeman, MT 59715 Landscape Architect Red Barn Montana 3084 Thorpe Road Belgrade, MT 59714 Letter to City of Bozeman Re: East Frontage Road – Site Plan Application Bozeman, MT October 14, 2020 Page 3 of 4 L:\193190\_Site Plan Application\City Cover Letter.doc 1.2 Project Location The project is located just east of the I-90 interchange on the Frontage Road. There is currently no approach or public access to the vacant lot. A vicinity map of the project site is included on the cover sheet of the Development Review drawings. 1.3 Project Schedule The construction for the “pad-ready” site is anticipated to commence in the spring of 2021, with completion slated for fall of 2021. The timeline for the building construction is not yet known, as the exact use and building footprint has not been decided. 2. General Site Information 2.1 Legal Description: A parcel of land in the SE ¼, SE ¼ of Section 8, Township 2 South, Range 6 East, Principal Meridian Montana, Gallatin County, Montana. 2.2 Site acreage is 4.39 acres. 2.3 The site along with adjoining properties to the east and west are zoned M-1 (Light Manufacturing). 2.4 There are no existing structures on the property. 3. Site Access 3.1 Currently there are no access points to the site. 3.2 An MDT approach application has been submitted and coordination with MDT will commence to construct a single approach onto the site. 3.3 Location and extent of the street vision triangles for the proposed approach are shown on the preliminary Entry Detail design drawing (C5.0). 4. Site Design 4.1 The site will be built up to create a property that is ready for building construction. A portion of the wetlands near the western property boundary will be undisturbed and will remain in its current state. Preserving a continuous area of wetlands will provide the site with a natural aesthetic (see the included Wetland & Watercourse document). 4.2 The site grading is designed such that if the building were to be constructed and parking area paved, the stormwater infrastructure will provide the necessary capacity/conveyance to appropriately control all site runoff. 4.3 A low-impact stormwater design was used to tie the entire site into the wetland area that will be preserved. All runoff from the parking area will be routed toward curb cuts that discharge into biofiltrations swales, with the runoff ultimately ending up in a detention pond that utilizes the existing wetland topography & treatment. Letter to City of Bozeman Re: East Frontage Road – Site Plan Application Bozeman, MT October 14, 2020 Page 4 of 4 L:\193190\_Site Plan Application\City Cover Letter.doc 4.4 Per the landscape plans prepared by Red Barn Montana, the parking lot will be screened from both I-90 to the south and the Frontage Road to the north. Landscaping around the building and within curb islands is subject to change according to the future use of the constructed building and accompanying parking spaces needed.
