MEMORANDUM OF UNDERSTANDING
BETWEEN IRVINE RANCH WATER DISTRICT O~
AND CITY OF NEWPORT BEACH, CITY OF SANTA ANA
AND MESA CONSOLIDATED WATER DISTRICT
REGARDING THE FOUR AGENCY INTERCONNECTION STUDY
Background:
Irvine Ranch Water District (IRWD), City of Santa Ana, Mesa Consolidated Water District and City
of Newport Beach, collectively the "Agencies" and each an "Agency," have initiated a project to
study the adequacy of emergency interconnections between the potable water systems of these
agencies for the purpose of improving reliability. Currently the Agencies have a number of
emergency interconnections between them. In addition, each of the Agencies has both groundwater_
and imported water supply sources sufficient to meet their normal operating needs.
The Four Aeency Interconnection Studv Project:
The Agencies have expressed an interest in a joint investigation to study the adequacy of existing
interconnections in various emergency outages or extreme drought conditions. The project will
inventory and analyze the adequacy of the existing interconnections, define operational requirements
for each interconnection, and quantify the availability of water supply from each agency in various
scenazios. A request for proposals was issued to complete the Four Agency Interconnection Study
(the "Study"). The scope of work for the Study includes the following:
• Identify and chazacterize demand requirements and supply sources for each Agency
• Identify and chazacterize existing interconnections for each Agency
• Create a hydraulic model
• Identify and model potential emergency and supply outage scenazio for each Agency
• Recommend interconnection improvements for each Agency
• Cost Estimate and potential grant funding opportunities
Requests for Proposal for engineering services were sent to five firms: AECOM, Brown and
Caldwell, DCSE, RBF Consulting, and Stantec Consulting. Each of the four Agencies reviewed and
ranked the four proposals. The Agencies' evaluation of the proposals resulted in a recommendation
of RBF to complete the Study. Representatives from the Agencies met with RBF and negotiated a
final scope and cost of $127,000.
The cost of the Study shall be shared among the Agencies. Each of the four Agencies will pay a
proportional share of the cost based on a combination of the total number of existing interconnections
and miles of pipes in the study area for each agency. The cost to be allocated to each Agency shall be
as follows:
1
Percent
Agency Participation Agency Cost
City of Newport Beach 17.5% $22,367
Mesa Consolidated Water District 19.3% $24,629
City of Santa Ana 17.5% $22,368
Irvine Ranch Water District 45.7% $58,336
Total $127,700
IRWD will provide staff time as the Project Manager of the Study. Each of the Agencies will provide
staff time to collect necessary information and participate in project meetings as necessary to
complete the Study.
The Agencies agree to contribute the $127,700 as set forth above. Any additional amount approved by
the Agencies for the Study, at their proportional share of the percentages set forth in this MOU, shall
require written approval of each party agency. The Agencies may collectively elect to terminate this
MOU at any time with each Agency being responsible for its percentage share of the cost incurred up
to the date of the termination. Each Agency may separately elect to terminate their participation in
this MOU at any time, but will be responsible for its percentage share of the cost approved by the
Agencies up to the date of the termination.
Participation in the Study does not obligate any Agency to proceed with any interconnection project.
The Agencies contemplate that they may, at each Agency's option, proceed with interconnection
projects under a further agreement(s) to be developed following the Study.
This MOU may be executed in one or more counterparts, each of which shall be deemed to be an
original and all of which together shall be considered one and the same MOU.
