CANOPY HOTEL BOZEMAN
ENGINEERING DESIGN REPORT
JULY 2024
Purpose and Introduction
The purpose of this report is to explain how water, sanitary sewer, and storm drainage
improvements will be designed to meet the City of Bozeman requirements and Montana
Public Works Standard Specifications (MPWSS) to provide service to a new hotel
building in downtown Bozeman, Montana.
The project is located on the north side of East Babcock Street between South Rouse
Ave. and South Church Ave. The property is comprised of West 17-feet of Lot 18 and
Lots 19 through 28 in Block A of Rouse’s First Addition to the City of Bozeman. The
property totals 0.91 acres in size and is located within Bozeman’s Downtown Business
District (B-3). The site is currently developed with an existing one-story retail/
administrative structure, site landscaping and site hardscape including asphalt parking
& drive lanes, sidewalks, and plazas. Vehicle access currently exists from the alley to
the north, S. Rouse Avenue to the west, and E. Babcock Street to the south.
The proposed redevelopment includes the demolition of the existing building and
construction of a new multi-story 197-room hotel with a ground floor restaurant and roof-
top lounge. Site improvements will include pedestrian sidewalks, plazas, landscaping
and streetscape features. The hotel building will also include a two-level below-ground
parking garage.
Design Report
Water
The property has an existing live water service connected to the 8-inch water main in E.
Babcock Street. This service is proposed to be abandoned at its connection point with
the water main in conjunction with demolition activities at the site. The estimated
existing domestic water demands being removed with the existing building are
summarized in Table 1 below with supporting assumptions and calculations provided in
Appendix A in accordance with C.O.B. DSSP Section V.A.4 and the 2017 Water Facility
Plan.
Table 1:
Estimated Existing Water Demands (Being Removed)
Average Day Max. Day Peak Hour
Existing Building -(509.8) gpd -(0.81) gpm -(1.06) gpm
The domestic water demand for the new 197-room hotel building is estimated using
actual water meter data from four comparable facilities within the City of Bozeman. The
hotels chosen for comparison are also located in downtown Bozeman and contain
restaurant and bar amenities. The new estimated domestic water demands for this
project are summarized in Table 2 below with supporting assumptions and calculations
provided in Appendix A in accordance with C.O.B. DSSP Section V.A.4.

Table 2:
Estimated New Water Demands
Average Day Max. Day Peak Hour
New Building Demand 15,760 gpd 25.2 gpm 32.8 gpm
Irrigation at the site will also be supplied from the building’s public water supply.
It is assumed that a new 4-inch domestic water service and 6-inch fire service line will be
extended to the new building from the 12-inch ductile iron water main in S. Rouse
Avenue. Final service sizing will be verified by the mechanical engineer in accordance
with the Uniform Plumbing Code, actual fixture unit counts, and fire protection system
requirements. The services will be Class 51 ductile iron and be installed per the City of
Bozeman Design Standards and Modifications to Montana Public Works Standard
Specifications (MPWSS).
The fire flow requirement for the new building is 1,500 gpm based on building size and
construction type as determined following International Fire Code Appendix B criteria
Fire hydrant flow reports were provided by the City Engineering Department for the
nearest existing fire hydrants to confirm available flows in accordance with C.O.B. DSSP
Section V.A.4 (max day + fire flow = 1,525 gpm). The hydrant flow data indicates an
available fire flow of 3,600 to 12,400 gpm before dropping below a residual pressure of
20 psi. A new fire hydrant will also be installed near the fire riser room at the NW corner
of the building which will connect to the 12-inch water main in S. Rouse Avenue. The
project fire flow determination and fire hydrant flow reports are provided in appendix A.
Sewer
The property has an existing live sewer service connected to the 24-inch sewer main in
S. Rouse Avenue. This service is proposed to be abandoned in conjunction with
demolition activities at the site. The estimated sewer demands being removed with the
existing buildings are summarized in Table 3 below with supporting assumptions and
calculations provided in Appendix B in accordance with C.O.B. DSSP Section V.B and
the 2015 Wastewater Facilities Plan.
Table 3:
Estimated Existing Sewer Demands (Being Removed)
Average Day (gpd) Peak Hour (gpm)
Existing Building -(529.4) gpd -(1.30) gpm
The sewer demand for the new 197-room hotel building is also estimated using actual
water meter data from the four comparable facilities within the City of Bozeman. This
may be slightly conservative as some of the facilities’ irrigation demand is also likely
included with the water meter records which is not contributing to their sewer demands.
The new estimated domestic sewer demands for this project are summarized in Table 4
below with supporting assumptions and calculations provided in Appendix B in
accordance with C.O.B. DSSP Section V.B.

Estimated New Sewer Demands
Average Day (gpd) Peak Hour (gpm)
New Building Demand 15,760 -

Total Sewer Demand 15,897 45.13
It is assumed that a new 8-inch sewer service will extend from the new building to the
existing 24-inch sewer main in S. Rouse Avenue. Final service sizing for this project will
be verified by the mechanical engineer in accordance with the Uniform Plumbing Code
and actual fixture unit counts. The new sewer service line will be SDR-26 PVC and will
be installed per the City of Bozeman Design Standards and Modifications to Montana
Public Works Standard Specifications (MPWSS).
Storm Drainage
Existing Conditions: The existing project site consists of one single-story administrative/
retail building, concrete and asphalt paved areas, and lawn & landscaped spaces. The
site is relatively flat with the building raised in the center and runoff draining toward S.
Rouse Avenue to the west, E. Babcock Street to the south, and the alley to the north.
No existing stormwater management controls are evident at the site. Site runoff
ultimately flows to the city storm drains located in S. Rouse Avenue and S. Church
Avenue.
Stormwater Quantity: The proposed site development includes a new multi-story
building with a footprint and roof that will cover most of the property. Pedestrian
sidewalks, plazas, landscaping and streetscape improvements are proposed around the
west and south sides of the site. A paved alley setback is prosed along the north side of
the building with access to mechanical rooms and covered operations/maintenance/
receiving areas.
All the stormwater from the building roof areas will be collected and conveyed via piping
to an underground chamber designed to retain & infiltrate the 10-yr, 2-hr design storm.
Stormwater runoff from the sidewalk areas fronting S. Rouse Avenue and E. Babcock
Street will continue to drain towards the street and be conveyed via curb and gutter to
the existing storm drains in S. Rouse Avenue and S. Church Avenue. The non-covered
areas in the alley setback will drain towards the alley and will ultimately be conveyed to
the existing storm drains in S. Rouse Avenue and S. Church Avenue. Overflows from
25-yr and larger storm events from the on-site retention system will be conveyed via
sidewalk drainage chase to S. Rouse Avenue.
With the underground retention chamber capturing and infiltrating the design storm
runoff volume from the large roof areas on-site, the post-development runoff volumes
and flow rates from this site are expected to decrease significantly from the existing
condition. Stormwater runoff calculations for the above-mentioned drainage areas are
provided in Appendix C.
B23-017 Canopy Hotel Bozeman Page 4 of 4
Stormwater Quality: As mentioned previously, stormwater runoff from the building roof
areas will be collected and routed to a sub-surface chamber facility designed to capture
and fully retain/infiltrate the flow from the 10-yr, 2-hr storm event. The design retention
volume has also been confirmed to have enough storage capacity to capture the first
half inch of rainfall from the building roof area as shown in the stormwater runoff
calculations provided in Appendix C.
Runoff from the paved alley setback will flow to the alley, which is primarily collected and
conveyed to the east where it connects to the storm drain in S. Church Avenue. It then
flows through a stormwater treatment unit located in S. Church Avenue south of Main
Street. The existing treatment unit is expected to have adequate capacity to handle the
alley setback drainage area since this project is decreasing the runoff volume and flow
rate draining to the alley (see the stormwater runoff calculations provided in Appendix
C).
Infiltration: Geotechnical drilling investigations were conducted at the site in June 2023
and February 2024. Groundwater was observed in 5 bore holes ranging in depths of 15
to 23.5 feet below the ground surface. Two groundwater monitoring pipes were also
installed on opposite sides of the existing building with ongoing monitoring during 2023
and 2024 showing seasonally high groundwater levels reaching levels of 13.5 and 14.6
feet below the ground surface.
The bottom of the proposed infiltration chambers will be approximately 5 to 6 feet below
the ground surface and will be over-excavated to tie into native gravels which were
encountered at depths ranging from 3.8 to 8.7 feet deep. Therefore, it is anticipated that
the underlying soils will be conducive to infiltration and groundwater will be sufficiently
deep to allow for a subsurface retention/infiltration strategy to be successful at this site.
The geotechnical investigation logs and on-site groundwater monitoring results are
provided in Appendix C.

Summary
Notes:
1. Downtown Bozeman Hotels were used as a comparison because they were recently constructed, have high occupancy rates
and exhibit similar uses as the proposed Boutique Hotel Mendenhall.
2. Because irrigation is minimal Downtown, average day sewer demands are assumed to be
approximately equal to average day water demands.
