January 2025 Project No. 05021.28 WATER DESIGN REPORT FOR MEADOW BRIDGE SUBDIVISION BOZEMAN, MONTANA 1.1.1 GENERAL INFORMATION This report describes the existing and proposed water mains which have been proposed to serve the new Meadow Bridge Subdivision in Bozeman, MT. The water and sanitary sewer infrastructure to serve the proposed development is from the City of Bozeman and is located within the right-of-way surrounding the project site. A new water main extension through the proposed Alley A will serve the lots adjacent to Alley A and will connect to the existing water main on either side to create a loop. The other lots will have services extended from existing mains within South 23rd Avenue, Last Loop Drive, and Blackwood Road. 1.1.2 EXTENT OF WATER WORKS SYSTEM The proposed site will utilize existing water mains within South 23rd Avenue, Last Loop Drive, and Blackwood Road. A new 8-inch ductile iron water main is proposed to extend within city right-of-way within an alley to serve the lots adjacent to the alley. The new water main will connect to the existing mains within Kurk Drive and Parkway Avenue. The existing water mains and proposed extensions will serve the proposed subdivision. The water supply will be provided by the City of Bozeman. 1.1.3 ALTERNATE PLANS No alternate plans were considered for this project. 1.1.4 SITE CONDITIONS There are no known or confirmed geologic hazards/unusual features for this site. Recent geotechnical borings indicate that topsoil exists in depths from zero (0) inches to twelve (12) inches throughout the site. The topsoil layer is underlain by poorly graded gravel at an average depth of one (1) foot. Groundwater was encountered during the
Water Report Page 2 of 4 January 2025 geotechnical exploration and subsequent groundwater monitoring at an average depth of 6 feet. The approximate groundwater flow is northerly. 1.1.5 WATER USE DATA The water demand for the proposed site was calculated based on City of Bozeman Design and Construction Standards (Draft 7/1/2024). The water distribution system serving the project will be designed and installed in accordance with the MDEQ Circular 1 and the City of Bozeman Modifications to MPWSS. 1.1.6 FLOW REQUIREMENTS A hydraulic model has been prepared to analyze the proposed and existing water mains. WaterCAD software was utilized to model the existing and proposed water mains. See Appendix A for an image of the WaterCAD model layout. The average daily demand (ADD) is based on the average daily usage of 135 gallons per capita per day (GPCD) at 2.17 people per dwelling unit. Dwelling units (DU) per lot were assumed based on lot sizes and feasibility of construction based on setbacks and allowed lot coverages. Lots greater than 9,000 square feet (SF) were assigned 3 DU, lots between 6,000 SF and 9,000 SF were assigned 2 DU, and lots less than 6,000 SF were assigned 1 DU. Peaking factors of 2.3 and 3.0 were applied to the calculated ADD to calculate the Maximum Day Demand (MDD) and Peak Hour Demand (PHD), respectively. The total water demand for the subdivision is summarized below. See Appendix B for the full water demand calculation details. ADD= 99 DU * 2.17 people/DU * 135 GPCD = 29002 GPD = 20.14 GPM MDD = ADD * 2.3 = 20.14 GPM* 2.3 = 46.32 GPM PHD = ADD * 3.0 = 20.14 GPM * 3.0 = 60.42 GPM Water demand for the system was evaluated by adding the required fire flow of 1,750 GPM to the MDD. Maximum fire flow demands are based on a worst-case scenario of a 4,800 SF Type V-B three-family dwelling without an automatic sprinkler system meeting NFPA 13R requirements. Therefore, the following MDD plus fire flow demand for this project is: Fire Flow = MDD + 1,750 GPM = 46.32 GPM + 1,750 GPM= 1,796.32 GPM The fire flow test data for the hydrants nearest to the proposed subdivision were provided by the City of Bozeman, see Appendix D. The model utilized hydrants #2340 and #2084 to provide hydraulic model flow data and calibrate the model. A “C” factor
Water Report Page 3 of 4 January 2025 of 130 was used for the Hazen Williams pipe roughness as required per the City of Bozeman Design Standards for ductile iron pipe. The results from the WaterCAD model have been provided in Appendix C. The model’s results show the existing and proposed main extensions will adequately supply the required domestic demands for the project during all scenarios (ADD, MDD plus Fire Flow, PHD). The MDD plus Fire Flow scenario included an evaluation of the existing hydrants within the proposed subdivision. Based on this analysis, the minimum fire flow available within the proposed subdivision is 2,949 GPM at hydrant 2341, which is above the minimum fire flow requirement of 1,750 GPM, so the hydrant supply is adequate. 1.1.7 SOURCES OF WATER SUPPLY Water treatment will be provided by the City of Bozeman. 1.1.8 PROPOSED TREATMENT PROCESSES Water treatment will be provided by the City of Bozeman. No additional treatment is proposed. 1.1.9 SEWAGE SYSTEM AVAILABLE The existing and proposed sewage system is a gravity sewage collection system which will collect sewage from the proposed residential buildings and convey the sewage into the City of Bozeman’s sewer collection system. 1.1.10 WASTE DISPOSAL There will not be any waste disposal on-site. Water is to be provided by the City of Bozeman. 1.1.11 AUTOMATION Automation is not proposed, water will be provided by the City of Bozeman. 1.1.12 PROJECT SITES The existing project site is approximately 25.32-acres and is currently undeveloped. The site is located within Gallatin County and is surrounded by existing developments. There are no known sources of pollution that may influence the quality of water supply or interfere with the effective operation of the water works system.
Water Report Page 4 of 4 January 2025 1.1.13 FINANCING The project will be funded through private financing. 1.1.10 FUTURE EXTENSIONS Future extensions are not expected for the project area. The site is surrounded by existing residential subdivisions so there is no room for expansion, so no future stubs are provided. Any future water main extensions will need to be reviewed and approved by the City of Bozeman and DEQ prior to construction. Should you have any questions, I can be reached at 406-922-4308 to further discuss this report. Sincerely, Bobby Egeberg, PE Bozeman Land Development Manager
