Water Mains 3 2/14/2025
1.1.1 Extent of Water Works System
City of Bozeman water mains exist in streets adjacent to the Stockyard.
Water supply to this area is from an existing 18” diameter water main from
Lyman Creek Reservoir which supplies the neighborhood water mains.
This project will provide approximately 1235 linear feet of 8” water main
connecting to existing mains in 3 locations, which will improve system
connectivity. New water mains will be in public street rights-of-way and
easements. Five (5) new fire hydrants are proposed with the
development.
Individual domestic service connections and individuation fire service lines
(where required) are proposed for the existing sale barn building. Two (2)
8” water main stubs are proposed for future extension as needed for
individual site development. The proposed water system improvements
are shown on the Water Plan attached at the end of this report.
The Stockyard water main extensions have been designed in accordance
with Montana Department of Environmental Quality Circular 1, and the
City of Bozeman Design Standards and Specifications Policy.
Construction specifications will be Montana Public Works Standards and
Specifications (MPWSS), and the City of Bozeman Modifications to
MPWSS.
1.1.2 Alternate Plans
Due to the project’s location within the City of Bozeman, extension of
public mains was the only water supply alternative. Distribution
alternatives were explored, and the proposed design was selected to
provide main looping and eliminate dead end segments.
1.1.4. Site Conditions
The Stockyard project is located in the northwest and southwest
quadrants at the intersection of East Griffin Dr and Story Mill Rd. The
property was previously occupied by an auction house, restaurant, several
single-family residences and associated outbuildings. The site is gently
sloping to the west and south.
A geotechnical investigation was conducted, and the report is provided as
an attachment to the infrastructure submittal. In summary the
geotechnical investigation found a variable depth of fine-grained soils
overlying gravel sediments. The depth to gravel varies between 3 and 13
feet.
Water Mains 4 2/14/2025
Groundwater monitoring was conducted throughout the 2022 season and
found seasonal high groundwater depths ranged from 2’ to greater than
13’ below existing grade. Groundwater is flowing to the west and is
assumed to discharge at the East Gallatin River which is the western
boundary of the southern part of this project. The range of groundwater
depth encountered was largely due to the rolling topography of the site
with some wells located at lower or higher relative locations. After site
grading, high groundwater will more consistently be about 10’ below the
surface.
1.1.5. Water Use Data
Domestic and lot irrigation water will be provided by the City of Bozeman
Municipal system. This project is located within the planned service area
of the City’s system.
Water use per square foot of office, retail, and restaurant was estimated
based on DEQ Circular 4 – Table 3.1. Conversion factors and usage rates
used to derive per square foot rates from per unit rates are shown below
in Table 1. These values along with typical design values from City design
standards and facility plans were used to calculate total water usage for
the property as shown in Table 2.

in Table 2.
1.1.6. Flow Requirements
Flow Requirements
As stated above, the peak hour water demand is estimated to be 143
gpm. The proposed water mains will also provide fire protection water
supplies (fire flow). Final fire flow requirements for each site are unknown
at this time.
Fire Analysis Summary
Fire flow analysis was carried out using a combination of observed field
data, as-built drawings, and WaterCAD hydraulic modelling software.
Existing system geometry for the model component was based off survey,
as-built drawings, and aerial photograph data. Hydrant leads were each
assumed to be 6” diameter. A Manning’s roughness coefficient of 130 was
used for all piping. The Lyman Reservoir which supplies the subject
service area was hydraulically modelled based on data in the City’s 2017
Water Facility Plan update. A hydrant flow test was conducted by the

engineer as described on the attached WaterCad Model Exhibit. Data
from this this test was used to calibrate the hydraulic model.
Several flow scenarios were chosen for model analysis. Existing average
day and max day use for the model was based on data obtained from the
City’s 2017 Water Facility Plan update. Average day flows were used for
model calibration and max day flows for fire flow determination. For
determining max day flows, Lyman reservoir peak hour demand, Pear
Street Booster Station Peak pump capacity, and house counting were
used. As described in the Facility Plan, the Pear Street Booster Station
transfers water from the Northeast Pressure Zone, where the Stockyard
Property is located, into the South Pressure Zone. This configuration
informs the existing and future demand allocation used in the hydraulic
model.
These water flow rates were then used to project usage for the Stockyard
as well as existing and obligated future off-site uses. A minimum fire flow
residual pressure of 20 psi, minimum working pressure of 35 psi as well as
a maximum velocity of 15 feet per second in any water main were used as
primary constraints for this analysis.
Due to the proximity of this development to the Lyman Reservoir and the
resulting system pressure, Fire flow capacity for this system is primarily
limited by the maximum velocity constraint. The projected fire flow
available at each proposed hydrant location are listed on the attached
WaterCad Model Exhibit and range from approximately 2,530 gpm to
3,500 gpm.

Re: Soil Corrosivity Sampling and Testing
Stockyard Properties, Bozeman, MT
Dear Ms. Huyser:
Allied Engineering Services, Inc. (AESI) was retained to perform soil corrosivity sampling and testing
across the Stockyard Properties site to determine if the on-site soils are corrosive to ductile iron pipe
(DIP) (for water main infrastructure). The test pit locations were selected by Stahly Engineering to
provide coverage of the site. This letter summarizes the site conditions, soil sampling, laboratory testing
results and analysis, and the corresponding corrosion protection recommendations. Please see
attachments for test pit location maps, laboratory testing data, and the corrosion design decision model
that used (from the Ductile Iron Pipe Research Association and Corrpro Companies, DIPRA-Corrpro).
We completed the following as per our scope of work:
• Reviewed AESI’s geotechnical report for the Stockyards Properties dated July 29, 2021.
• Reviewed the DIPRA-Corrpro Design Decision Model document (attached).
• Reviewed groundwater monitoring data collected June 15, 2021 through the present.
• Logged nine test pits on June 15, 2021, located as requested by Stahly Engineering to provide
coverage of the property area.
• Collected five composite samples of soils across the site within the typical water main depth
range of 4.0 to 8.0 feet.
• Completed analytical testing for moisture content, resistivity, chlorides, pH, sulfide ions, and
redox potential. This testing was conducted by Energy Labs in Helena.
• Analyzed site conditions and lab data according to the DIPRA-Corrpro Design Decision Model.

SUBSURFACE CONDITIONS
On June 15, 2021, AESI conducted a geotechnical investigation of the subject property. The work
included the excavation of nine test pits (TP-1 through TP-9), the installation of 4 PVC groundwater
monitoring wells (in four of the test pits), and the preparation of a final geotechnical report. According
to the AESI geotechnical report, the project site is underlain by intermixed fluvial and floodplain deposit
soil conditions that are typical for the northeast side of Bozeman, including about 1.0 to 6.0 feet of
topsoil and/or mixed fill, an intermediate layer of fine grained native silty sand and sandy clay with
varying thickness to depths of about 6.5 to 13.0 feet, and native clean sandy gravel beginning below the
fine-grained soils. Note that in some locations (TP-3 and TP-7), the random fill extended deeper in
trenches and/or potential borrow pits, up to a depth of 14.5 feet. In the other test pits, the clean sandy
gravel deposits extended to the bottom of the 10.0 to 11.5-foot-deep test pits.
Groundwater was encountered in most test pits at a depth of 11.0 to 13.5 feet (the shallowest was at
4.5 feet in TP-6). AESI performed groundwater monitoring of the wells installed in the test pits from June
2021 to August 2021. Groundwater monitoring in TP-6 indicated levels ranged from 4.5 to 5.5 feet. All
remaining wells were dry during monitoring.
Table 1 provides a summary of the soil and groundwater monitoring conditions observed in the test pits.
For additional discussion, please see our geotechnical report dated July 29, 2021.

DIPRA ANALYSIS AND RECOMMENDATIONS
The site condition and lab testing data were evaluated using DIPRA-Corrpro’s Table 2 and Table 3 to
obtain corrosion likelihood and corrosion consequence scores. These scores were then plotted in the
DIRPRA Design Decision Model Two-Dimensional Matrix to obtain the DIPRA corrosion protection
recommendation. Table 6 provides the DIPRA scores and recommendations for each of the soil samples.
Please see the attached sheets to see plots of each sample.

Notes: 2) For likelihood scores of 1 to 20, the DIPRA recommendation is “as manufactured with shop coat.”
3) For likelihood scores of 21 to 40, the DIPRA recommendation is “V-Bio Enhanced Polyethylene Encasement.”
4) For likelihood scores of 41 to 50, the DIPRA recommendation is “V-Bio Poly Encsmnt w/ Zinc Coated Pipe.”
SUMMARY AND RECOMMENDATIONS
Based on the typical depth of the water mains (5.0 to 8.0 feet), the pipe will primarily run through a
variety of different soil types across the site. The soils will consist of silts, clays, sand, and gravels.
Trench backfill during water main installation will consist of a mix of these soils as the layers varied
across the site. Five composite samples were collected from across the site at a depth of 4.0 to 8.0 feet
for corrosivity potential for ductile iron pipe. Based on laboratory testing results, Samples 1 through 4
consisting of sandy lean clay, sandy silt, and sandy gravel were non-corrosive soil. Sample 5 consisting of
silty sand/sandy clay measured a resistivity of 2,000 ohm/cm which can be considered a corrosive soil.
According to the DIPRA Decision Model, the likelihood score is the deciding factor for most projects
regarding whether a soil is corrosive and to what extent corrosion protection is recommended.
Consequence scores (the second input to the decision matrix) must reach a medium to high threshold
value before they affect the corrosivity and protections assessment. Since consequence scores are
typically low, they are usually of no effect, as in this case. For this project, all five samples scored a
consequence score of 8. Based on the DIPRA document, the use of V-Bio Enhanced Polyethylene

Lab measurement of analytes considered field parameters that require analysis within 15 minutes of sampling such as
pH, Dissolved Oxygen and Residual Chlorine, are qualified as being analyzed outside of recommended holding time.
Solid/soil samples are reported on a wet weight basis (as received) unless specifically indicated. If moisture corrected,
data units are typically noted as –dry. For agricultural and mining soil parameters/characteristics, all samples are dried
and ground prior to sample analysis.
Radiochemical precision results represent a 2-sigma Total Measurement Uncertainty.
