1.0 INTRODUCTION
Purpose
This Master Plan Utility Report has been developed to achieve the following
objectives: identify utility design and model crite ria, present model results,
and summarize sizing and capacity of on and off-sit e infrastructure.
Proposed Development
University Towne Center (UTC) is a 17.65-acre Comme rcial Development
located near Yellowstone Highway and University Bou levard. The project
has access to public roadways in Yellowstone Highwa y, Tamana Drive, and
Mikan Drive. Utilities are available in some public roadways and through
adjacent development areas. The Draft Final Plat an d Construction Drawings
are underdevelopment and will be submitted shortly (anticipated prior to
March 1, 2026). The Client requests that the City t ake this study under
review and provide any early comments or approvals to help facilitate an
expedited Plat application and Construction Drawing s review. The property
is currently zoned Community Business Center consis tent with the proposed
and intended use.
The final contours of the proposed development are anticipated to range
between 4,854 and 4,856 MSL. Overall, the existing site is flat
(approximately one foot of fall from North to South ) with the change in
elevation to be insignificant in the model results. Elevations used for
culinary water model elements were taken from the p reliminary surface
design.
Existing Utility Services
Potable Water – The City of Rexburg (City) can provide pressuriz ed
potable water to the development area. Hydrant Test s (see Appendix A) were
recently performed to establish boundary conditions for the purpose of
developing a hydraulic model, see below. Hydrants w ere tested individually,
not simultaneously, so there may be additional pres sure drawdown effects
using multiple connection points to service and loo p the development area,
but the effects are anticipated to be negligible.
1. Hydrant Test #1 (Yellowstone Highway). Mainline ava ilable is 12-inch
mainline, static pressure = 87 psi, Flow Condition 1 = 1,900 GPM at 80
psi, Flow Condition 2 = 6,434 GPM at 20 psi. Initia lly it was anticipated
to include a mainline connection with the water mai n in Yellowstone
University Towne Center, Rexburg ID

Highway however the model results do not require th is condition to
satisfy fire flow.
2. Hydrant Test #2 (near Comfort Care Dental). Mainlin e available is 12-
inch, static pressure = 85 psi, Flow Condition 1 = 1,841 GPM at 79 psi,
Flow Condition 2 = 6,665 GPM at 20 psi.
3. Hydrant Test #3 (along Mikan Drive, near proposed d evelopment
access). Mainline available is 12-inch mainline, st atic pressure = 85 psi,
Flow Condition 1 = 1,950 GPM at 81 psi, Flow Condit ion 2 = 8,788 GPM
at 20 psi.
Overall, the City has a very adequate distribution system and can provide a
high level of utility service to the development ar ea without any off-site
improvements. The proposed distribution system as m odeled (junctions, pipe
alignments, pipe sizes, hydrant locations, and cust omer elements) is shown
on Figure 1. The distribution system includes loopi ng from Mikan Drive to
Comfort Care Dental, through the development area. A third connection
from Yellowstone Highway is not warranted in the mo del. Water usage
estimates for Max Day and Peak Hourly demands are c alculated for each
customer element according to type of use, anticipa ted building size, and lot
size
Irrigation – The property does not have access to secondary i rrigation and
proposes to utilized potable water for landscape ir rigation. Approximately
2.0 acres of the original 17.65 acres is currently planned to require
irrigation. The client proposes to utilize xeriscap e, where allowed and
feasible, to further reduce irrigation demand on th e potable water system.
The irrigation requirement is anticipated at 0.25 i nch per acre at an
efficiency of 80% or a total demand of 0.3125 inch per acre. The average
irrigation density for the develop is 11.33% of the gross lot area. A
customer element is also provided for the irrigatio n of commonly held
landscape areas by the development.
Sanitary Sewer – The City has collector main sewer lines at the e dge of the
development. These main sewer lines will be extende d as shown in Figure 2
for the development. The additional load from the d evelopment is estimated
below using the Average Day water demands from each customer element.

2.0 UTILITY DESIGN AND MODEL CRITERIA
Potable Water Criteria
Table 1 and Appendix B contain a summary of the pot able water design and
model criteria for the proposed development area. T he potable water model
uses demand data that includes both irrigation and potable water.
A graphical representation of the distribution syst em network and model
elements are shown on Figure 1. Information for the model elements
including inputs and analysis data is included in A ppendix B. The following
four scenarios were completed.
1. Model Calibration
a. Compare results from Hydrant Test #2 with similar d emand
near system connection.
b. Compare results from Hydrant Test #3 with similar d emand
near system connection.
2. Peak Hour Demand to demonstrate the network can pro vide the new
demands and maintain a pressure greater than 40 psi .
3. Maximum Day Demand plus Fire Flow to demonstrate th e network
can provide the new demands and maintain a minimum of 25 psi at
the hydrant and 40 psi at any other junction.
Model configuration and setup data are as follows.
Model Software is Bentley WaterCAD, version 24.00.0 3.22
12-inch thru 8-inch mainlines are Ductile Iron (DI) pipe with a Hazen
Williams coefficient of 130.
Fire Hydrants are connected to mainlines with 6-inc h ductile iron
(DI) pipe with a Hazen Williams coefficient of 130.
Pipe lengths are drawn graphically according to imp orted base maps
in the model’s coordinate system except near the bo undary
conditions.
Inputs junctions are modeled as a Reservoir-Pump bo undary
conditions using a three-point pump definition. Sta tic and Flow
Condition data was developed by a third-party contr act with 3D Fire,
see Appendix A. Pipe lengths in connection with the boundary
condition were overridden to allow for improved gra phics display.
Junction elevations were estimated from a prelimina ry grading plan.
Overall, the site is flat and the effects negligibl e.

Demand data was input using the “Costumer Meter” ju nction type.
All demands were modeled as “Fixed”. Demands were associated
with the nearest junction or pipeline.
Model output tables are labeled to provide addition al context and included
in Appendix B.
The pipe network as shown on Figure 1 meets the des ign input and
performance criteria on Table 1. A minimum fire flo w of 4,250 GPM was
modeled for most hydrants, with the exception of th e Hydrant 1 and 2 that
only needs to achieve 2,500 GPM to meet the coverag e for Lot 8, Pad 11.
These two proposed hydrants along with the existing hydrant near Custom
Care Dental provide the required building coverage. The model confirms
that minimum residual pressures are achieved even w hen modeled at fire
flows of 5,000 GPM.
Automatic sprinkler demands have been estimated for proposed buildings
according to building type, occupancy, and hazard c lassification. The
demands are listed on Table 1 and are equal to or l ess then the modeled
minimum fire flow demand of 4,250 GPM. The fire flo w demands could be
satisfied in the model with 8-inch mainlines howeve r design guidance from
the National Fire Protection Association (NFPA) rec ommends a connection
size that limits pipe velocities to less than 20 fe et per second. To satisfy this
guidance and increase residual pressures in the dis tribution system during a
fire event, the mainline servicing the fire line co nnection to Lot 3 - Pad 7
was modeled as a 10-inch. The 10-inch mainline prov ides about 18 psi
greater pressure (59 psi vs 41 psi) at Junction 30 (fire line connection to Pad
7) over 8-inch mainlines, during a fire event. Addi tionally, dual 10-inch
connection are modeled for Lot 4 and a 12-inch conn ection and looped 8-
inch connection is modeled for Lot 5 to provide gre ater flexibility in future
planning.
Sanitary Sewer Criteria
Table 2 contains a summary of the design and model criteria. The collection
system is divided into two contributing areas, West Collection Area and East
Collection Area (see Figure F-2). Using Average Day Demand (ADD) data
developed for the potable water demands, including estimates for
infiltration, the West Collection Area estimates to collect 13,730 GPD while
the East Collection Area estimates to collect 29,92 7 GPD. Using a Peak
Hour Factor of 4.0 yields a maximum flow rate of 38 .1 GPM and 83.1 GPM
from the West Collection Area and East Collection A rea, respectively. An 8-
inch mainline at a minimum design grade of 0.4% has a capacity of 172
GPM flowing at 50% full and can be used on all main lines.
