Water Demand Memorandum
215 RIVERSIDE AVENUE
Newport Beach, CA March 27, 2019
Purpose
The purpose of this report is to present the results of the evaluation of the water demand
analysis for the 215 Riverside Avenue project.
Project Site Location
The existing site is located in the City of Newport Beach, CA. The site is to the northwest of
the intersection of Riverside Avenue and Avon Street.
Existing Conditions
The site area is 0.4 acre. Based on our review, the existing two-story building currently
serves as office space, along with a restaurant. Sheet G7-W of the City of Newport Beach
water atlas map shows that there is an existing 8” waterline in Avon Street along with a
12” waterline in Riverside Avenue, fronting the property. A fire hydrant flow test was
performed for a nearby project, located on WCH approximately 2,000 feet easterly from
the 215 Riverside Avenue project. A copy of the G7-W water atlas map is included as
Attachment 1. The fire hydrant location (address) and test results are presented on the
following page.

square feet. The area calculations for the proposed project are as follows:
Main Level: 2nd Level:
Water Demand Calculations
The water demand for the proposed site is based on Irvine Ranch Water District (IRWD)
demand coefficient for commercial development. The IRWD value of 220 gallons/ksf/day
was used, along with the total area calculation of 3,106 square feet. The water demand
calculations are as follows:
· (3,106 square feet /1000) x 220 = 685 gallons per day for the proposed
development;
· 685 gallons/day = 0.8 ac-ft per year.

Conclusion
The water demand calculations show that the proposed project will require approximately
0.8 ac-ft of water per year.
