HomeMy WebLinkAbout001 Response to Conceptual Review BCity of Bozeman Planning Dept Re: Site Plan Review April 28,2023 Responses to Concept Review by Ref # 2. BMC 38.410.130. Water Adequacy: The development will need to satisfy the water adequacy code requirement prior to a future site plan approval. If sufficient water rights cant be provided to offsets the development's annual demand then a cash-in-lieu of water rights (CILWR) payment will be required. The City assesses the CILWR fee at a rate of $6,000 per acre-foot. The fee determination will take place during the site plan review, however if there are any questions or if a preliminary review is desired please contact Griffin Nielsen with the Engineering/Utilities Department directly at gnielsen@bozeman.net or (406) 582-2279. The City encourages the use of groundwater wells to supply irrigation demands, which in turn will reduce the CILWR fee. Applicant must obtain a pre-determination from the DNRC demonstrating that a well groundwater well may be permitted under Montanas exempt appropriation or that provide the water right documentation if existing prior to finalization of the CILWR fee determination. Finally, the City would like to make the owner aware of an available CILWR rebate of approximately 20% for residential units if high-efficiency fixtures (toilets, washers, and shower heads) meeting the City Water Conservation Division standards are installed. The rebate would be released at occupancy and requires an agreement defining the terms and amount rebate be finalized and executed prior to final plan approval. If the owner is interested or has any questions please reach out to Griffin Nielsen. Cash-in-lieu of water rights were provided with the original Baxter Meadows Subdivision. The water demands anticipated from the development of this lots have been provided to Griffin Nelson for cash-in-lieu determination. 3. DSSP Section V.A. - A water design report must be prepared by a professional engineer for the proposed project with the site plan submittal. The water distribution system must be designed to meet the maximum day demand plus fire flow and the peak hour demand. A water design report is included within the provided “Sewer, Water & Stormwater Design Report”. Average daily, maximum day and peak hour demands are computed within the report. Water fixture sizing charts are included in Appendix A of the report. 4.DSSP Section V. B. - Sanitary Sewer System Design Criteria: The applicant must provide an estimate of the peak-hour sanitary sewer demand certified by a professional engineer for the proposed project prior to site plan approval. DSSP V.B.3 - New sewer lines shall be sized to flow at no more than 75-percent of full capacity at peak hour 1 conditions upon the full build-out of the development. The effects of the proposed development's sewer loading on existing downstream sewer lines shall be analyzed. The proposed project is located within the Baxter Meadows lift station service area. Currently, the Baxter Meadows lift station is fully dedicated. The proposed project cannot exceed the lift station capacity reserved for the subject property without an upgrade to the lift station and associated force main. The applicant must demonstrate the design capacity reserved for the parcel relative to the proposed peak-hour wastewater flow for the proposed project. A sewer design report is included within the provided “Sewer, Water & Stormwater Design Report”. Average daily and maximum daily flow rates are computed within the report. In addition, a separate letter has been prepared and submitted that demonstrates that the proposed development does not exceed the capacity reserved in the Baxter Meadows lift station for the development of this lot. 5. BMC 38.220.080 A. 2.g. - The applicant must submit a peak hour trip generation value to the City to determine whether a traffic impact study is required. Included within the site plan submittal is a peak hour trip generation estimate and request for the waiver of the requirement for the completion of a traffic impact study. 6.DSSP Section II A. 4. - The applicant must include a storm drainage plan, with the site plan submittal, with post-construction storm water management controls that are designed to infiltrate, evapotranspire, and/or capture for reuse the post-construction runoff generated from the first 0.5 inches of rainfall from a 24-hour storm preceded by 48 hours of no measurable precipitation. A stormwater design report is included within the provided “Sewer, Water & Stormwater Design Report”. The original subdivision design accounted for runoff from the development of this lot. Unfortunately the original estimate of impervious surface was underestimated and a portion of the overall stormwater will have to be retained on site. Two retention areas are proposed on site to capture the difference in post-construction runoff. 7.DSSP Section II C. - The applicant must provide on-site detention with release rates limited to predevelopment runoff rates with the site plan submittal. Retention ponds must be sized based on a 10-year, 2-hour storm intensity. On-site storm water retention is proposed for this site to handle the difference between the original design calculations and the proposed site development. The storm water retention ponds are sized based on a 10-year, 2-hour storm intensity. 8.Montana Post Construction Storm Water BMP Design Manual - The proposed project is located in an area that is known to have seasonally high groundwater. The applicant must demonstrate, with the site plan submittal, that seasonal high groundwater will not impact the function or maintenance of the proposed facilities. Industry guidance recommends a three-foot minimum separation from the bottom of the proposed facility to the underlying groundwater table. The applicant must provide local seasonal high groundwater elevations to support the proposed design. Included within the site plan submittal is a “groundwater contour map” interpolating groundwater elevation across the site and analyzing the separation of groundwater with the proposed bottom of pond elevations. Groundwater is estimated to be 3.21’ and 3.71’ below the bottom of each of the proposed retention ponds. 2 9.BMC 38.270.020 - Construction Routes: A construction route map must be provided showing how materials and heavy equipment will travel to and from the site. A “Construction Route Map” is included on Sheet C1.3 showing the route of construction materials and heavy equipment to and from the site. 15.The striping for the parking has become worn and faded. The applicant must re-stripe the parking area as necessary. The applicant acknowledges that the striping in the parking areas has become worn and faded and is agreeable to re-striping the parking areas. 16.The applicant must provide and file with the County Clerk and Recorder's office executed Waivers of Right to Protest Creation of Special Improvement Districts (SIDs) on City standard record form. The improvement are listed below. A draft City standard template has been uploaded to the City Documents folder. a. Street improvements to Davis Lane between Baxter Lane and Cattail Street including lighting, signalization, paving, curb/gutter, sidewalk, and storm drainage. b. Street improvements to Cattail Street between Davis Lane and Ferguson Avenue including lighting, signalization, paving, curb/gutter, sidewalk, and storm drainage. c. Street improvements to Equestrian Lane between Caballo Avenue and Davis Lane including lighting, signalization, paving, curb/gutter, sidewalk, and storm drainage. d. Street improvements to Equestrian Lane between Vaquero Parkway and Harper Puckett Road including lighting, signalization, paving, curb/gutter, sidewalk, and storm drainage. e. Intersection improvements at Cattail Street and Davis Lane including lighting, signalization/channelization, paving, curb/gutter, sidewalk, and storm drainage. f. Intersection improvements at Cattail Street and Ferguson Avenue including lighting, signalization/channelization, paving, curb/gutter, sidewalk, and storm drainage. g.

Intersection improvements at Equestrian Lane and Ferguson Avenue including lighting, signalization/channelization, paving, curb/gutter, sidewalk, and storm drainage. i. Intersection improvements at Equestrian Lane and Harper Puckett Road including lighting, signalization/channelization, paving, curb/gutter, sidewalk, and storm drainage. A draft Waiver of Right to Protest Creation of Special Improvement Districts on the City standard form has been included in the site plan submittal for review. The document will be executed and recorded upon notice of acceptability from the City. 17. Fire requires a minimum of 20 feet clear in the alleys and the alley adjacent to lot 3 is a 30 foot right-of- way. The parking is located outside of the right-of-way so the alley parking layout would be allowed by engineering. Acknowledged, thank you! 18.As proposed acceptable. 19.Per 38.570 BMC, lighting is subject to standards include illuminance at building entrances or property lines, and fixture design. Please include information on proposed lighting and refer to cited code for standards. An electrical site plan has been included. There is only building lighting and no parking lot 3 lighting. 20. Per 38.550.050.B, 75% or greater of the proposed trees and shrubs must be drought tolerant species as identified in code. Please include quantities and calculations in the table. Quantities and % have been shown along with irrigation amounts and other typical details 21.Per 38.530.070.C BMC, untreated blank walls visible from a public street, pedestrian-oriented space, common usable open space, or pedestrian pathway are prohibited. See cited code for additional information. Dimensions have been placed on elevations and no blank walls occur at streetscape and open spaces. 22. Per 38.530.060.B BMC, impact resistant materials must be used for the first 18 inches above the walking surface when facades are adjacent to city sidewalks. Please demonstrate that the proposed materials for the described area are impact resistant.Brick wainscot is from 30” -36” around entire perimeter of building therefore impact resistant at all walking surfaces 23.
