SUBJECT: UNIT III UPPER NEWPORT BAY PROJECT (MAINTENANCE AND
ENHANCEMENT OF UNIT I IN -BAY BASIN) BIOASSAY - COOPERATIVE
AGREEMENT WITH COUNTY OF ORANGE/HARBOR, BEACHES AND
PARKS (C -2987)b)
RECOMMENDATION:
Authorize the Mayor and City Clerk to execute the Cooperative
Agreement with the County of Orange to share in the cost of
Bioassays required for the Unit III Upper Newport Bay Project.
DISCUSSION:
In January the Upper Newport Bay Executive Committee requested
the City to take on a lead role similar to the City's role on earlier In -Bay
projects. That role was accepted and City Council approved an Engineering
Services Agreement with John M. Tettemer and Associates to provide project
management and design services necessary to prepare plans, specifications,
contract documents, agreements; and to obtain permits, environmental
clearance, and funding for the project. A copy of the most recent Project
Status report to the Executive Committee is attached for information.
Bioassay studies are required by State and Federal agencies to
test dredge material for toxic contaminants and compatibility with the ocean
disposal site. The U.S. Army Corps of Engineers and the Environmental
Protection Agency have established a procedure for testing sediment samples
for grain size distribution, chemical analysis and impact on living marine
animals. In recent years, the tests have become more involved than the
Bioassay required for Unit II Project in 1986. Currently Bioassays can require
6 to 9 months to perform the required testing and obtain required agency
approvals.
The Executive Committee requested the City and the County to
coordinate work required for the Unit III maintenance project with the U.S.
Army Corps of Engineers Upper Newport Bay Feasibility Study. The scope of
the proposed Bioassay has been coordinated with the County and the Corps
of Engineers to provide for the Corps of Engineers Feasibility Study, the Unit
III Project, dredging anticipated near Dover Shores, and dredging anticipated
by the County at the Newport Dunes. The cost of the proposed Bioassay is

estimated to range from $125,000 to $150,000 depending on the testing
program still to be approved by the EPA. Our consultant is working with EPA
and anticipates approval of the testing program in June. The Corps of
Engineers has agreed to credit the cost for the Bioassay towards the local
share of the cost for the 50% Federal/50% Local cost sharing required for the
Upper Newport Bay Feasibility Study.
This agreement provides for $75,000 from the County of Orange
for the Bioassay. In general, terms of the agreement provide as follows:
1. COUNTY Agrees:
a. To pay City $75,000 within 30 days of receiving
invoice from the City.
b. To assist City in coordinating Bioassay with Corps of
Engineers and resources agency.
2. CITY Agrees:
a. To retain consultant and administer preparation of
Bioassay.
b. To provide copies of approved Bioassay to County
and Corps of Engineers.
C. To provide final accounting of Bioassay to the County.
It is anticipated that The Irvine Company will also participate in
funding a portion of the cost of the Bioassay. Budget amendments to provide
these funds in the current fiscal year have been prepared and will be
forwarded to the Finance Department when this Agreement is approved by
the County Board of Supervisors and The Irvine Company share is approved
by Irvine Company management.
