AMENDMENT TO THE SAN DIEGO CREEK/UPPER NEWPORT BAY
WATERSHED COOPERATIVE AGREEMENT AND THE NEWPORT BAY/SAN
DIEGO CREEK WATERSHED SEDIMENT CONTROL MONITORING AND IN-
CHANNEL MAINTENANCE PROGRAM COOPERATIVE AGREEMENT (D98-034)
SIJMMARY
Thc amendment to the "San Diego CreeWUpPer Newport Bay Watershed Cooperative Agreement" proposes to
add the Orange County Flood Control District, the City of Lake Forest, the Santa Aha Regional Water Quality
.
Control Board, and the Irvine Ranch Water District to the existing agreement: Additionally, the amendment
expands the scope of the agreement frOm strictly sediment control to cover additional watershed enhancement
issues such as alleviating nutrient impa/nnents in Newport Bay.
The Newport Bay/San Diego Creek Watershed Cooperative Agreement amends previous cooperative agreements
for the construction of in-channel facilities and sediment monitoring programs by adding the City of Lake Forest
and providing.fUnding for expanded sediment monitoring and maintenance of In-Channel Basin 1.
RECOMMENDATION
That the City Council approve the "Second Amendment to the Cooperative Agreement San Diego Creek/Upper
Newport Bay Watershed" along with the "Cooperative Agreement Newport Bay/San Diego Creek Watershed
Sediment Control Monitoring and In-Channel Maintenance Program" and authorize the Mayor and the City
Clerk to execute said agreements.
FISCAL IMPACT
The City's share for program participation during F.Y. 1998-99 has been estimated at $17,322 and is budgeted in
the Public Works Department's current operating budget. The City's share for the proposed F.Y. 1999-2000
budget is estimated at $17,746 and will be requested during the F.Y. 1999-2000 budget process. The sediment
program is an annual program established to meet the new regulatory requirements of the Santa Ana Regional
Water Quality board and will require an annual appropriation. The agreement will reduce the City's proportionate
fiscal share of the programs.
DISCUSSION
In 1983, the Cities of Irvine and Newport Beach, The Irvine Company, the County of Orange and the California
Department of Fish and Game entered into the "Cooperative Agreement- San Diego Creek/Upper Newport Bay
Watershed". The agreement was entered into for the purpose of providing a forum to evaluate and assess progress
towards implementing the Comprehensive Storm Water Sedimentation Control Plan prepared for SCAG by the
Cities of Lrvine and Newport Beach under the Federal 208 Water Quality Planning Program. The agreement
Amendment to the San Diego Creek/Upper Newport Bay Watershed Cooperative Agreement and the Newport
Bay/San Diego Creek Watershed Sediment Control Monitoring and h-Channel Maintenance Program
Cooperative Agreement
January 5, 1999
Page 2
established an executive committee consisting 'of a representative from each agency and made the committee
responsible for reviewing and reporting the progress being made in implementing the Sediment Control Program.
The agreement recognized that there were other parties within the watershed that also had responsibilities for
controlling sediment and that they may be required to participate in furore project implementing agreements.
Subsequently, this agreement was amended in 1985 to add the City of Tustin.
'In December of 1997, the Upper Newport Bay Executive Committee convened to discuss the implementation of
new Total Maximum Daily Load (TMDL) requirements for the Upper Newport Bay Watershed and the current
watershed planning efforts. As a result, it was unanimously decided that the Committee should expand its role to
other watershed issues beyond sediment impairments and add the Orange County Flood Control District, the City
of Lake Forest, the Regional Water Quality Control Board (Santa Ana Region) and the Irvine Ranch Water
District to the Executive Committee. The attached agreement has been revieWed and approved as to form by each
of the parties respective counsels.
The second agreement entitled "The Newport Bay/San Diego Creek Watershed Sediment Control Monitoring and
In-Channel Maintenance Program Cooperative Agreement (D98-034)" seeks to amend in their entirety the
existing agreements entitled "San Diego Creek Sedimentation Monitoring Program (August 20, 1996)" and
"Agreement Between the County of Orange, the Orange County Flood Control District, the City of Irvine, the
City of Tustin, the City of Newport Beach and The Irvine Company' and construction of additional in-channel
facilities in San Diego Creek in furtherance of the Newport Bay Watershed- San Diego Creek Comprehensive
Stormwater Sedimentation Control Plan (September 25, 1994)." The existing San Diego' Creek Sediment
monitoring program evaluates the transport of sediments to Lower Newport Bay and the effectiveness of retarding
basins, in-channel basins, and channel stabilization projects in the San Diego Creek Watershed. The cost of the
existing program is shared equally among all parties and will not exceed $8,500 plus a percentage equal to the
consumer prices index for each twelve month period through the agreement expiration on June 30, 2000. The
agreement covering the construction on additional in-channel facilities also governs the maintenance of' the in-
channel sedimentation basin. The City's most recent payment was for maintenance that was completed in May
1994 and amounted to $64,000 or 16% of the total cost to remove sediment from the basin.
The proposed new agreement is based on the inclusion of the City of Lake Forest and .new regulatory
requirements initiated by the Regional Water Quality Control Board. The requirements recalculate .the Total
Maximum Daily Load and necessitates additional basin monitoring and more timely maintenance of the in-
channel basins. The original construction agreement involved three in-channel basins, however, Irvine Ranch
Water District has committed to full maintenance of the two of the basins. Therefore, the proposed agreement
involves only the maintenance of In-Channel Basin 1. This agreement has also been reviewed and approved as to
format by each of the parties respective, counsels.

Bay/San Diego Creek Watershed Sediment Control Monitoring and h-Channel Maintenance Program
Cooperative Agreement
January 5, 1999
Page 3
The Executive Committee has reached agreement on a new funding formula for allocating costs for sediment
monitoring in the Newport Bay/San Diego Creek Watershed and maintenance of In-Channel Basin 1 based on a
weighted share of parties land area, sediment source, population and benefit ratio within the watershed. The
benefit ratio has a weighted share of 35% and is a subjective evaluation related to each participant's proximity to
Newport 'Bay, access to recreational uses and public or private benefit from Newport Bay's economic value. The
funding formula provides for sufficient funds to be contributed annually to allow for cleaning of In-Channel Basin
1 within 5 years and vegetation studies in Newport Bay within 3 years. The City of Tustin proportionate share for
participating in these agreements is reduced to 7.07% of the total anticipated expenditure and is estimated to be
$17,322 for Fiscal Year 1998-99 and $17,746 for F.Y. 1999-2000.
