1.0 PURPOSE/PROJECT DESCRIPTION
This water system analysis was conducted to check the capacities of the proposed onsite private
underground fire distribution system and potable water supply lines that will serve the
proposed Palomar Forum Parcel "A" - Amazon. The on-site system will be looped with two
connection points, one at an existing 12" lateral Polyvinyl chloride (PVC) service off of Eagle
Drive and the other at an existing 12" PCV service off of Greyhawk Court. Both fire line
connection will utilize an 8" double detector check valve (DDCV). The connection services an
onsite looped fire system consisting of an 8" PVC line that will serve the site.
2.0 CRITERIA AND METHODOLOGY
The modeling of the onsite fire service lines was completed using the EPANET 2.0 program
(EPANET). Usage of the water and sewer plans provided the scaled distances for the project.
The schematic used in EPANET can be found on Attachment A.
2.1 Head Loss Across Fittings
Minor losses encountered in the Ductile Iron Pipe (DIP) fittings along the pipelines were
neglected in the model (i.e. elbows, tees, etc.). The headloss (HL) across the backflow apparatus
was addressed and modeled using the method described below.
The Watts 8" double detector check valve (DDCV) was modeled as a general purpose valve
(GPV) in series with a check valve. The HL curve can be found on the specification sheet for the
Watts DDCV on Attachment B. This information was used to develop Figure 1 below, which
displays the HL curve created for usage in EPANET to model the flow within the system.
Additional information for the proposed backflow device can be found on Attachment B.

2.2 Roughness Coefficients
A Hazen-Williams roughness coefficient value of 120 was used for the PVC pipes in the system.
2.3 Modeled Demand Flows
The current site improvements do not propose a building, however this analysis took into
account the possibility of future development.
We followed the 2013 California Fire Code (CFC) Appendix B to obtain fire-flow requirements for
a future building (see Attachment D). Using Table B105.1, it was determined that the worst-case
required fire-flow would be 8,000 gpm. By assuming the future building will have fire sprinklers,
the required flow can be reduced by 75 percent, resulting in a required flow of 2,000 gpm. For
the purpose of this analysis, the flow was only reduced by 50 percent. The calculated fire-flow
system criteria enabled the following scenario to be tested.
Scenario 1 - Based off of the current site requirements, a demand of 1,333 gpm was
supplied to the system and distributed between the three hydrants.
2.4 Tie-In Pressures Available
Existing flow and pressure data from the public system in Eagle Drive and Greyhawk Court was
taken from a flow analysis performed by the City of Carlsbad Fire Department (CCFD) on
06/15/2021. To model this scenario in EPANET the pressure available was modeled as a
reservoir with a total head equivalent to the Total Head Available given in the analysis provided
IN
by the City. This pressure test data can be found on Attachment C to this report, and is
summarized in the table below.
Table 1: CCFD Flow Test Results
Hydrant NO Static Static Elevation (ft) Total Head Reservoir
Pressure (psi) Pressure Available Number
(ft of head) (ft)
unk 124 287 413 700 1
3.0 CALCULATONS AND CONCLUSIONS
This performed analysis confirms that the underground fire distribution system will be adequate
to provide 4,000 gpm to the site for Scenario 1. Providing each hydrant a minimum residual
pressure of 20 pounds per square inch (psi) during fire flow demand.
Please see Attachment E.1 and E.2 for the pipe velocities and pressures.

Atpeakdemand, this water system is capable of providing a fire flow discharge at 20 psi in excess of 8,000 gpm.
However, this exceeds the City's 10 fps maximum velocity criteria. The requested fire flow of 4,000 gpm meets the
City's minimum pressure and maximum velocity criteria.
Note that the City estimates static pressure based on the LWL of the tank in that zone. Therefore, the residual pressure
can potentially be higher than static, even during a fire flow event.

B104.1 General. The fire-flow calculation area shall be the
total floor area of all floor levels within the exterior walls,
and under the horizontal projections of the roof of a building,
except as modified in Section B 104.3.
