1.0 INTRODUCTION
1.1 PURPOSE OF STUDY
The purpose of this study is to analyze the City of Newport Beach public sanitary sewer
systems for the existing and proposed conditions for the proposed Ritz-Carlton Residences
project. In addition, this report includes recommendations for sewer upgrades, if any, that
would be required to accommodate wastewater flows associated with the proposed project
development.
1.2 SITE DESCRIPTION
The project site is the Marriott Resort Hotel & Spa and it encompasses a total area of
approximately 9.53 acres in the City of Newport Beach. The existing site consists of the
hotel & spa with 532 hotel rooms, along with associated parking. The Ritz-Carlton
Residences project is in the southerly portion of the property and will encompass 3.95
acres of the total area. Adjacent land uses include other commercial development to
the east, a golf course (Newport Beach Country Club) to the west, and residential
property to the north and south.
The site is located westerly of the intersection of Newport Center Drive and Santa
Barbara Drive. A Vicinity Map is shown below.
Project information along with the Vesting Tentative Tract Map are included as Appendix
1 of this report.

1.3 EXISTING SEWER FACILITIES
Wastewater from the site currently discharges to the City’s public sewer system through
two 8” sewer laterals on the east side of the project site. The laterals connect to the
existing 10” sewer main in Newport Center Drive.
The location of this sewer system is shown on the Public Sewer Exhibit, included in this
report as Appendix 2. As-Built Plans of the existing sewer system is included in Appendix
3.
1.4 PROPOSED DEVELOPMENT
The proposed project development will consist of demolition of one of the existing hotel
buildings and construction of a new building. The proposed building will be in the
southerly portion of the project site and will consist of 159 hotel-branded residences
and 5 levels of subterranean parking. Construction of 35,000 square feet of amenity
space is included in the proposed development. A Project Description, prepared by CAA
Planning, and an email correspondence from MVE Architects (Appendix 1) describe the
type and quantity of proposed hotel-branded residences, the number of existing hotel
rooms that will remain, and the square footage of proposed amenity space.
The proposed unit count and type will be as follows:

2.0 METHODOLOGY AND EXISTING SEWER FLOWS
The City of Newport Beach has published design criteria for public sewer systems. A
copy of this criteria, along with City of Los Angeles flow coefficients for commercial
areas, are included in this report as Appendix 4. The design criteria includes the
following parameters:
· Design flow shall not exceed half-full;
· Manning’s roughness coefficient (Manning’s “n”) shall not be less than
0.013;
· Wastewater calculations shall be 265 gpd for development size between 151
to 250 units;
· Peaking factor for development size between 151 and 250 units shall be
3.40 times average flow.
The investigation included obtaining the current wastewater flows in the existing sewer
system that will be accepting the project flows. This was achieved by a flow test of two
weeks, conducted from September 29 – October 15, 2021, by USCubed. The manhole
(#K19_046) location is shown on the Public Sewer Exhibit (Appendix 2). The Sewer
Monitoring Report is included as Appendix 5.
The manhole was monitored using Hach Flo-Dar Flow Meters, and included the
following analyses:
PA2021-296
SEWER ANALYSIS REPORT December 2021
Newport Center Hotel, LLC 4 The Ritz-Carlton Residences, Newport Beach
The Flo-Dar methodology used by USCubed consists of transmission of a digital
Doppler radar beam that interacts with the fluid and reflects signals at a different
frequency than that which was transmitted. The flow-depths were detected by ultrasonic
pulse echo. Flowrate was then calculated based on the continuity equation, as follows:
Table 1 presents the results of the peak wastewater flows that were obtained from the
flow monitoring operations, along with the calculated flow-depths and percent-full for
the 10” sewer main at the location of manhole K19_046. The sewer monitoring report
is included as Appendix 5. The Kutter Flow-Depth calculations are included in Appendix
7. The results in show the sewer main is 29% full for the existing condition.

3.0 PROPOSED SEWER FLOWS
The proposed project wastewater peak flows were calculated for this project using the
following information, from the Project Information (See Appendix 1):
· 159 Proposed hotel-branded residences
· 373 Existing hotel rooms to remain
· 35,000 Square feet of proposed amenities
The sewer generation calculations and tables are included in Appendix 6 of this report.
The proposed development is anticipated to generate net new flows of 0.161 cfs, which
would result in a proposed condition flow rate of 0.498 cfs in the existing 10” City sewer
system. There are two existing 8” sewer laterals that are available to service the project
site. The project wastewater will discharge through 1 or both existing 8” laterals, which
connect to the existing 10” sewer main in Newport Center Dr.
The Kutter Flow-Depth calculations for the proposed condition are summarized in Table
2. The results show the existing 10” sewer main will be 35.2%-full considering the
proposed conditions. Therefore, the existing sewer main will have capacity to accept the
anticipated flows from the proposed project.

4.0 RESULTS AND CONCLUSIONS
The calculations and results presented in this report demonstrate that the existing sewer
system will not be adversely impacted by the wastewater flows associated with the
proposed project.
The sewer monitoring report shows that the existing 10” sewer main in Newport Center
Drive is currently at 29%-full for the existing peak wastewater flows. The proposed
development will connect to the existing 8” laterals and discharge into the 10” sewer
main. The flow depth of the existing public sewer system with the proposed conditions
will be at 35.2%-full and will be in compliance with City of Newport Beach Design
Criteria. Therefore, no sewer upgrades will be required to accommodate the proposed
project development.

The construction is all going be Type IA.
The mix is still very much being debated however it currently stands as follows:
1BR 26DU
2BR 112 DU
3BR 18 DU
4BR 2
5BR 1
TOTAL 159 DU
There is no commercial program for the project. However the amenity program is substantial and is roughly 35,000 SF.
Still all conceptual but this will include: Club Rooms, Fitness, Spa, Lockers, Private Meeting Rooms, Kitchen Area, Viewing
Terrace, Etc.
I am not sure how many keys are being demolished. Kevin Martin from Lyon should be able to provide that information.
Hope this helps.
Thank you.

FOOTNOTES TO SGFs TABLE
(a) SFC rates for these facilities have historically been published in SFC ordinances.
(b) Bureau of Sanitation will determine the flow based on the information given by
applicants for facilities with industrial discharge. The flow will be redetermined by
Sanitation inspectors annually based on water bills. If the actual flow exceeds the
previous year’s determined flow, the applicants will be charged for the difference.
If this type of facility is exempt from an industrial discharge permit, only the domestic
SFC will be assessed.
(c) The SFC for a bar shall be the sum of SFC's for all areas based on the SGF for each area
(ex. fixed seat area, public table area, dancing area).
(d) The determination of SGF for juice bars and coffee houses previously depended on the
extent of the actual food preparation in house, not by the types of food provided. Food is
assumed to be prepared offsite and as such, the three prior subcategories have been
consolidated.
1) SGF for no pastry baking and no food preparation is 720 gpd/1000 gr.sq.ft.
2) SGF for pastry baking only and no food preparation is 720 gpd/1000 gr.sq.ft.
3) SGF for complete food preparation is 25 gpd/seat, the same as a fast food
restaurant.
Juice bars and coffee houses do not serve any alcoholic drinks.
(e) Building construction includes trailers, field offices, etc.
(f) Cocktail lounge usually does not serve prepared food.
(g) Cold storage facilities are categorized as follow:
1) No Sales - the cold storage facility is used only for temporary storage, no selling
is involved. For example, cold storage facilities at the harbor temporarily store
seafood until it is distributed.
2) Cold storage w/ retail sales - the primary function of this facility is to support the
wholesale/retail operation of a store, such as supermarket freezers, refrigerators,
etc.
(h) Counseling centers include marriage counseling centers, alcohol/drug rehabilitation
/dependency centers, nutrition centers, diet centers, etc.
PA2021-296

(i) Part-time basis schools or dance studios should be charged as retail area - 50 gpd /1000
gr.sq.ft. Full-time basis schools should be charged by the number of students.
(j) Domestic waste is estimated at 50 gpd/1,000 square feet in addition to total process flow.
(k) Bureau of Sanitation will determine if an industrial permit is needed for health spas. The
first year flow is based on 650 gpd/1000 gr.sq.ft., and the Sanitation inspectors will
redetermine the flow annually based on water bill from the previous year. The applicants
are responsible for paying the difference of SFC.
Health club/spa includes lobby area, workout floors, aerobic rooms, swimming pools,
Jacuzzi, sauna, locker rooms, showers, and restrooms. If a health club/spa has a
gymnasium type of facility, this portion should be charged separately at the gymnasium
SFC rate.
Gymnasiums include basketball court, volleyball court, and any other large open space
with low occupancy density.
(l) Lobby of retail includes lounges, holding rooms, or waiting area, etc.
(m) Full service post offices include U.S. Postal Service, UPS, Federal Express, DHL, and
etc.
(n) The SGF for a college dormitory based on student capacity also includes the SGF for the
dormitory cafeterias.
(o) A bedroom is defined as an enclosed subdivision with 50 sq.ft. or more floor area in a
residential building commonly used for sleeping purpose, and is partitioned off to form a
habitable room.
(p) The SGF for schools based on the student capacity, covers the following facilities:
1) classrooms and lecture halls
2) professors' offices
3) administration offices
4) laboratories for classes or research
5) libraries
6) bookstores
7) student/professor lounges
8) school cafeterias
9) warehouses and storage areas
10) auditoriums
11) gymnasiums
12) restrooms
PA2021-296

It does not include water used by schools for swimming pools. When a school files an
application for addition of any of the foregoing facilities, the student population will be
reassessed and the total gpd for the new facility will be based on the number of students
increased since the last SFC was paid or when the City implemented the SFC for the first
time. The SFC for any school facility (ex. stadium, dormitory, etc.) not listed above, will
be based on the designated SGF for that category.
(q) The SFC for a TV or motion picture studio shall be the sum of SFC's for different
facilities in the studio, based on the SGF for each facility. A studio may include one or
more of the following facilities: audience viewing room, filming room, film processing,
storage area, etc.
(r) No independent tanning salons with shower were encountered during 1996 survey.
(s) Alternative basis of charge for City’s consideration. The prior square footage basis is
also presented should the City decide to continue charging on that basis.

Methods and Procedures
Utility Systems Science & Software provided Fuscoe with an off the shelf, non-proprietary
flow monitoring solution that included one state of the art Hach Flo-Dar® AV Sensor system.
The project course of action is listed below. The US3 team:
Assessed permitting and traffic control at the site on Newport Center Dr in Newport
Beach, CA.
Obtained a City Encroachment Permit, which required a formal traffic control plan.
Installed and removed traffic control in accord with approved traffic control plan per
site-specific California Temporary Traffic Control Handbook (CATTCH) requirements
for both the installation and removal of equipment.
Validated the site for suitability for sewer flow monitoring for the Newport Marriott
Residences Project.
o MHK 19_046 had flows entering the manhole from the east and the north.
o The site had moderate open channel hydraulics with minor turbulence from inflow
from the eastern line.
Installed and calibrated the flow monitoring equipment at the site per manufacturer
recommendations on 9/29/2021.
o Follow-up on the installation confirmed equipment was reading properly.
o Collected 15-minute interval depth and velocity data points over the entire
monitoring period.
Removed the equipment on 10/15/2021 and validated the data.
o All of the equipment went through diagnostic testing before and after the study
with less than a 1% deviation between manual and meter level readings and less
than a 5% deviation between manual and meter velocity readings.
o Equipment calibration was verified in accordance with manufacturer
specifications.
Prepared the data reports.
o The table below contains a summary of the average (Avg) and maximum (Max)
velocities (Vel) and levels (Lev) collected during this study as well as the
calculated flow rates (Flow) and depth versus diameter ratios (d/D).

How It Works
Flo-Dar® transmits a digital Doppler radar beam that interacts with the fluid and reflects back
signals at a different frequency than that which was transmitted. These reflected signals are
compared with the transmitted frequency. The resulting frequency shift provides an accurate
measure of the velocity and the direction of the flow. Level is detected by ultrasonic pulse
echo. Flow is then calculated based on the Continuity Equation:
Q = V x A, Where Q = Flow, V = Average Velocity and A = Area
Accurate Flow Measurements
Flo-Dar® provides the user with highly accurate flow measurements under a wide range of
flows and site conditions. By measuring the velocity of the fluid from above, Flo-Dar®
eliminates accuracy problems inherent with submerged sensors including sensor
disturbances, high solids content and distribution of reflectors.
