PROJECT BACKGROUND The North 3rd Apartments Project proposes to develop 5.86 acres of two existing vacant lots (Parcel Nos. RGG6409 & RGG6410) zoned as Residential Mixed-Use High-Density District (R-5) into a multi-family apartment housing complex. The project site is located near 701 N 3rd Ave, Bozeman, MT in Gallatin County. The project area is bounded to the north by the Homestead Townhouses Development, to the east by single family residential housing, to the south by high density residential housing, and to the west by Westlake Park. All 5.86 acres of the site will be disturbed. The proposed development includes seven (7) garden style apartment buildings and a clubhouse available for use by all residents. The apartment buildings are 4-story structures with 24-32 units per building, 216 units total. A vicinity map of the project site is provided in Figure 1-1. 1.2. PROJECT PURPOSE The project includes onsite and offsite water infrastructure improvements for the delivery of domestic water and fire flow demand to the development from the existing City of Bozeman (City) drinking water system. The purpose of this Water Design Report is to provide a description of the proposed water infrastructure improvements and to demonstrate that the improvements meet the water distribution design requirements included in the City Design Standards and Specifications Policy (Design Standards) and City Modifications to Montana Public Works Standard Specifications (MPWSS) Sixth Edition.

SITE CONDITIONS 2.1. GENERAL EXISTING SITE CONDITIONS The existing site is undeveloped land comprised primarily of grass and shrubs. There are no significant topography changes on the site. The site generally slopes towards the northeast with a total of 12-feet of elevation change. The surrounding land use is a mix of commercial, single-family residential, and multi- family residential. A geotechnical investigation was performed on the site in June 2022 by C & H Engineering and Surveying Inc. Seven test pits were excavated for investigation. The test pits all generally showed organic silty clay in the upper 1.5 to 2 feet, sandy lean clay to depths of 3.5 to 5 feet and poorly graded gravel with sand and cobbles from 6.5 feet to the bottom of the test pit. The Natural Resources Conservation Service (NRCS) Web Soil Survey (WSS) identifies the soil near the project site as 457A – Turner Loam. The project site is not located within a FEMA Special Flood Hazard Area (SFHA). The site is mapped on FEMA Flood Insurance Rate Map (FIRM) Panel 3000280816E, effective date April 21, 2021. The site lies within an unshaded FEMA Zone X, area of minimal flood hazard. See the FIRM Panel in Appendix A. 2.2. EXISTING WATER INFRASTRUCTURE The project is located in the City’s South Pressure Zone (South Zone). The South Zone is a pressure reduced zone supplied by a water storage reservoir located at the water treatment plant on Sourdough Road. The hydraulic grade line (HGL) of the zone is 5,125 ft. Pressures within the zone range from 6 pounds per square inch (psi) to 160 psi with static pressures in the immediate vicinity of the project approximately 140 psi. There are no water mains located in North 3rd Ave directly adjacent to the project; however, there are two 6-inch diameter stubs located near the northern boundary of Parcel No. RGG6409 in Ivan Dr. and North 3rd Ave and an 8-inch diameter stub located near the southern boundary of Parcel No. RGG6410 in North 3rd Ave. Water main located within a 0.25-mile radius of the project site is generally small diameter 4- or 6-inch water main serving single family residential homes. West of the project there are 8- and 10-inch diameter water mains located in Durston Road and North 7th Ave, respectively. All existing water mains in the area are constructed of ductile iron pipe. 2.3. GENERAL PROPOSED SITE DESIGN The proposed site will consist of seven (7) multifamily residential buildings and one clubhouse with laundry facilities, fitness equipment and offices. Characteristics of each building are identified in Table 2-1. Associated passenger vehicular parking and utility infrastructure will be constructed in conjunction with the buildings.

WATER DEMAND PROJECTIONS Water demand projections for the proposed development were calculated to size onsite and offsite water main improvements. The projections were made in accordance with the Design Standards Section V Subsection A – Water Distribution Lines Design Criteria. 3.1. DOMESTIC WATER DEMANDS Water demands for domestic water use were calculated based on an average day demand (ADD) of 170 gallons per capita per day (gpcd) and an occupancy rate of 2.17 people per dwelling unit in accordance with the Design Standards and the 2017 Water Facility Plan update, respectively. The water demands for the clubhouse were calculated by assuming an equivalent dwelling unit (EDU) demand based on an equivalent square footage and safety factor of 1.5 to account for additional demand from the proposed laundry facilities at the clubhouse. The total square footage of the apartment buildings is approximately 235,000 ft2 with 216 apartments (dwelling units); therefore, each dwelling unit is approximately 1,100 ft2. Based on this approximation and a safety factor of 1.5 the clubhouse is equivalent to 4 EDUs. Maximum day demand (MDD) and peak hour demand (PHD) were calculated using peaking factors of 2.3 and 3.0, respectively, per the Design Standards. The calculated domestic water demands for the development are provided in Table 3-1.

FIRE FLOW DEMANDS The fire flow demand or needed fire flow (NFF) for the proposed development was calculated using the International Fire Code (IFC) Appendix B as recommended in Section 5.2.2 of the 2017 Water Facility Plan Update. National Fire Protection Association (NFPA) 13R automatic sprinkler systems will be installed in all seven apartment buildings; therefore, a 25 percent reduction of NFF was applied in accordance with IFC Table B105.2. Additionally, a safety factor of 1.10 was applied to the IFC calculated NFF, per Section 5.5.4 of the 2017 Water Facility Plan Update. IFC Table B105.1(2) was used to calculate the fire flow and fire duration prior to automatic sprinkler credit and safety factors being applied. All buildings, including the clubhouse are construction type V-A. To determine the “fire-flow calculation area” for each building it was assumed that building floors had the same Water Design Report │ DEVCO North 3rd Apartments November 2022 6 area as the building footprint identified in Table 2-1. The calculated NFF for the proposed development is identified in Table 3-2.

PROPOSED WATER INFRASTRUCTURE IMPROVEMENTS 4.1. BASIS OF DESIGN The proposed water system was sized in accordance with the Design Standards based on the water and fire flow demand projections identified in Section 3. The design demand for the project is the combined MDD, 138 gpm, and NFF for the highest demand building, 2,900 gpm for 3-hours. See Table 4-1 for a summary of the water infrastructure improvements basis of design. Table 4-1: Basis of Design - Water Improvements Design Parameter1 Value Minimum Water Main Diameter 8-inch Water Main Pipe Material Ductile Iron Maximum Pipe Velocity 15 fps Minimum Fire Flow System Pressure 20 psi Minimum Fire Hydrant Spacing 350-feet Note: 1. Per City of Bozeman Design Standards 4.2. PROPOSED WATER MAIN IMPROVEMENTS The proposed water system is depicted schematically in Figure 4-1. The system is designed to create additionally water main looping along North 3rd Ave in the South Pressure Zone. There are four connection points to the existing system to create a loop around the proposed development and connect existing water mains in West Tamarack Street and West Peach Street. In total, the proposed improvements include 1,800- lineal feet of 8-inch diameter ductile iron water main, water services for each building, fire suppression connection for each building, fire hydrants, isolation valves and other necessary appurtenances to meet the Design Standards. The 8-inch main installed on the east side of the project will serve buildings A, C, E, and F while the 8-inch main installed in North 3rd Ave. will serve the clubhouse and Buildings B, D, and G. The proposed 8-inch ductile iron water main will meet American Water Works Association (AWWA) C151- 09 Ductile Iron Pipe Standards and be rated for an operating pressure of 250 psi. The water main will have an approximate inside diameter of 8.51-inches, per AWWA C151, and thickness of 0.27-inches. Under normal operating conditions (no fire flow demand), pipe velocities range from 0.2 to 0.6 fps for ADD and PHD, respectively. Pipe velocities under fire flow conditions are discussed in Section 4.3. G!. G!. G!. G!. G!. G!. G!.

FIRE FLOW ANALYSIS A fire flow analysis was completed using Bentley Systems WaterCAD water system modeling software to evaluate pipe velocities and system pressures during design flow conditions. Assumptions included in the model are identified in Table 4-2. Table 4-2: WaterCAD Fire Flow Analysis Model Assumptions Parameter Value Source Hazen-Williams Pipe Roughness "C" 130 Design Standards 8-inch Pipe Inside Diameter 8.51-inches American Cast Iron Pipe Company Available Fire Flow Flow = 3,000 gpm Duration = 3 hr 2017 Water Facility Plan Update (Figure 5-2) City engineering staff provided hydrant curves for existing hydrants located near the four proposed connection points to the existing water system. The hydrant curves were created based on the City’s hydraulic model and provide the available fire flow and residual pressure in the system at each hydrant. See Appendix B for the hydrant curves and other fire flow information provided by the City. The elevations of the four existing hydrants were approximated such that the hydraulic gradeline (HGL) at all four hydrants was constant under static conditions. Elevations of all junctions within the project site were assigned based on the finished grade surface elevations. The design demand condition (MDD of 138 gpm combined with NFF of 2,900 gpm for a 3-hour duration) was modeled at all junctions. The model was set up to allocate MDD evenly between all junctions on the two proposed water mains. The NFF demand was applied to each junction individually to evaluate fire flow conditions throughout the proposed water system. Modelling results are provided in Appendix C. At the design demand condition, each junction provided a residual pressure greater than 20 psi and a maximum pipe velocity less than 15 fps; therefore, the water mains are sized appropriately to meet the Design Standards at the design demand condition. See Table 4-3 for a summary of fire flow analysis results. Table 4-3: Fire Flow Analysis Results Summary Parameter Units Value NFF gpm 2,900 MDD1 gpm 138 Minimum Residual Pressure psi 105 Maximum Pipe Velocity fps 11.13 Notes: 1. MDD is allocated between the two proposed water mains (75 gpm demand on east main, 63 gpm demand on west main). Water Design Report │ DEVCO North 3rd Apartments November 2022 10 5. SUMMARY The proposed development is anticipated to demand a total of 63, 138, and 173 gpm for ADD, MDD, and PHD, respectively. The calculated NFF is 2,900 gpm for a fire duration of 3-hours. Proposed water infrastructure improvements include approximately 1,800-lineal feet of 8-inch diameter water main, fire hydrants, building water service connections, building fire suppression connections, and isolations valves designed in accordance with the City Design Standards. Hydraulic modeling was conducted to analyze pipe velocities and residual system pressure during the design demand condition of MDD combined with NFF. Model results demonstrate that the maximum pipe velocity is less than 15 fps and the minimum residual pressure is greater than 20 psi; therefore, the water infrastructure improvements are sized appropriately per City Design Standards.
