CITY COUNCIL AGENDA
ITEM NO. 12
TO: Mayor and Members of the City Council
FROM: Public Works Department
SUBJECT: REQUEST TO ALLOW IRVINE RANCH WATER DISTRICT TO SERVE
RECLAIMED WATER TO HARBOR RIDGE
RECOMMENDATION:
Direct staff to work with the Harbor Ridge Association and Irvine Ranch Water District
(IRWD) to come up with a proposal that will allow Harbor Ridge to be served with
reclaimed water.
DISCUSSION:
The Harbor Ridge Association requested the City of Newport Beach to allow them to
connect to the IRWD's reclaimed water system (see attached February 18, 2000 letter).
Harbor Ridge is located outside the IRWD boundaries and in the City's service area.
The State Government Code does not permit a water district to serve water within
another agency's boundaries without that agency's permission. If the City wishes to
allow this request, it will be necessary for the City Council to authorize this service by
adopting a resolution spelling out the conditions under which the service would be
allowed.
The Harbor Ridge Association has had informal discussions with both IRWD and the
City staff over the past few years concerning the use of reclaimed water to irrigate their
greenbelt areas. They are very interested in proceeding with this proposal if it is
determined to be economically feasible to purchase reclaimed water from IRWD at a
favorable rate, and the conversion costs are not too great.
The Harbor Ridge area's elevation and distance away from the City's Green Acres
Project (GAP) reclaimed water system in Jamboree Road prevents the City from
providing water from this source. IRWD has two possible locations in their reclaimed
water main system where a service point for Harbor Ridge could be provided. City staff
is working with IRWD to complete a hydraulic study evaluating the feasibility of both
possible points of service. Exhibit A is a colored sketch showing the IRWD reclaimed
system and possible connection points. A service connection at Point 1 would require
construction of approximately 3000 feet of water line to the entrance of Harbor Ridge at
Crestwood Drive. A service connection at Point 2 would require the construction of
approximately 2400 feet of water line to the same entrance point. Both proposed
service connection water lines would be in the public street right -of -way. In addition to

the construction of a new IRWD service connection water line, new water lines must be
constructed from the connection point to all of the water meter locations (approximately
40) within Harbor Ridge to provide the new reclaimed water service to the various green
belt areas. The construction costs for these facilities are estimated to be in excess of
$400,000 and will be borne by the Harbor Ridge Association. The separation of the
potable and reclaimed water systems must meet State Health Department standards as
well as being certified by the City's cross - connection crew at least once a year.
The range of options being explored by staff, IRWD and the Harbor Ridge Association
are between:
Direct service to Harbor Ridge by IRWD, with a IRWD water main in the
public streets and water lines in the Harbor Ridge streets constructed and
maintained by the Association, and;
IRWD selling the reclaimed water to the City through a master meter and the
City - providing service to Harbor Ridge through water lines constructed by the
City at Harbor Ridge expense.
The City will be required to regularly inspect our system to make sure the proper
separations are maintained, regardless of who constructs and owns the water service.
The goal of the Harbor Ridge Association to conserve potable water by using reclaimed
water for irrigation is commendable. The City intends to work closely with the
Association and IRWD to determine if an economical program can be put in place to
accomplish their goal. If it is the City Council's desire, staff will work with IRWD and the
Harbor Ridge Association to put together a formal program that will serve the needs of
Harbor Ridge and provide an example for the processing of similar requests.
Respectfully submitted,

The Honorable Mayor and
Members of the City Couni
3300 Newport Blvd.
Newport Beach, CA 92660
Dear Mayor Noyes and Council Members,
The Harbor Ridge Homeowners Association hereby requests permission to connect to Irvine
Ranch Water District's reclaimed water line for the purpose of watering our common greenbelt
areas. The IRWD line is adjacent to our Association boundary and can therefore, be easily
connected to our lines providing water to our common areas.
Permission to do this would provide great benefits to the City and the Homeowners Association.
Currently we are using approximately 39,782,380 gallons of potable water each year to water
our common greenbelt areas. This water could be saved for use as drinking water and as you
know all forecasts predict a shortage of potable water in future years in Southern California. It is
our plan to convert approximately one - fourth (114) of our irrigation pipes each year and if
allowed to do this the savings in potable water will be very impressive. For instance:
1" year potable water saved 9,945,595 gallons
2nd
year
19,891,190 "
3`d
year
29,836,785 "
4d'
year
39,782,380 "
51°
year
99,455,950
Each successive year, approximately 39,782,380 gallons of potable water can be added to the
four year total savings. To grant permission of this letter would give a strong statement of
Newport Beach's commitment for environmental matters. Additional use of this reclaimed water
would diminish excessive water the IRWD may want to discharge in San Diego Creek and the
Upper Bay in the future.
It seems like both parties could benefit from this proposal since the reclaimed water is currently
at our border and connection can be made. We have worked with your staff and they are
familiar with this proposal. At this stage it is believed that a resolution or motion approving use
of IRWD reclaimed water is all that is needed, but your staff can best advise you on the actions
that need to be taken by the City Council. Both your staff and the staff of IRWD have been very
cooperative in working with us to explore this proposal.
Thank you for your consideration of this proposal which would save potable water for the City
and permit the Association to use less expensive water for irrigation purposes. If you need
additional information, please feel free to contact me.

Hoose, Ha or Ridge Board President
