MICHAEL WALFORD, PUBLIC WORKS DIRECTOR DATE: MAY 7, 1991 SUBJECT: REPORT FROM CHIEF ENGINEER ON WILDCAT - SAN PABLO CREEKS CORPS OF ENGINEERS PROJECT. PROJECT NO. 7567-TX8604-90, NORTH RICHMOND AREA. SPECIFIC REQUEST(S) OR RECOMMENDATION(S) &BACKGROUND AND JUSTIFICATION I. Recommended Action: ACCEPT1his report on financial status of the Wildcat- San Pablo Creeks Project with attached financial sheets for Zone 7 and Drainage Area 73. APPROVE recommendation that$300,000 of Special District Augmentation Funds be allocated to the Wildcat - San Pablo Creeks Project to cover a portion of the funding shortfall. AUTHORIZE the Chief Engineer to indicate to the Corps of Engineers that the District is confident that the necessary local funding will be available for 1992 construction of the San Pablo Creek improvements between the railroad tracks and for 1992 construction on Wildcat Creek between the railroad tracks if the State includes sufficient Federal Flood Control Subvention Program Funds in its Fiscal Year 1991-92 Budget. AUTHORIZE the chair to send letters to the County's State legislators soliciting their support for funding the State's Federal Flood Control Subvention Program in Fiscal Year 1991-92. APPROVE the recommendation of the Design Team and Chief Engineer that the Corps of Engineers originally planned concrete lined channel should be installed as the improvement on San Pablo Creek between the railroad tracks and that said improvements are to be mitigated by extensive landscaping along the south bank of the channel. DIRECT staff to insure that said mitigation landscaping is included in the project.

Financial Impact: The construction of a concrete lining with mitigation planting in lieu of a gabion lined channel will result in a significant decrease in non-federal project costs and will reduce the Districts future maintenance costs. The Public Works Department will make a portion of the North Richmond Corporation Yard available to the Corps contractor to further reduce the non-federal project right-of-way costs. The attached financial status reports for Flood Control Zone 7 and Drainage Area 73 show a shortfall in local funding of $950,000. To date staff has identified the following potential sources of funds: Special District Argumentation Funds $300,000 Reduce R/W Costs Through Donations 90,000 Future Drainage Area 73 Fees 250,000 Sale of Remnant Properties 50,000 $690,000 The cost of the remaining improvements to be constructed is approximately $6,700,000. Our local costs share is approximately $700,000. III. Reasons for Recommendations and Background: On February 12, 1991, staff reported to the Board on the shortfall in funding for the Wildcat - ° San Pablo Creeks Corps of Engineers Project. Since then we have met with the Flood Control Zone 7 Advisory Board and contacted both San Pablo and Richmond indicating our funding problem and soliciting their assistance. On April 15, 1991 staff met with the City Council of San Pablo. We are also working with the City of Richmond to seek dedication of some of the needed rights-of-way along Wildcat Creek. These development dedications could reduce the local cost share by $90,000. The State Department of Water Resources is expected to owe $1,900,000 to Zone 7 and Drainage Area 73 by June 30, 1991. If the State does not fund the subvention program in Fiscal Year 1991-92 the district will have insufficient capital to fund both Wildcat and San Pablo Creeks construction in 1992. Under this scenario we propose that the San Pablo Creek improvements be funded and the Wildcat Creek improvements be deferred until 1993. There is no legal requirement that the State provide funding to the Department of Water Resources Federal Flood Control Subvention Program. The original draft State budget proposes $43 million for the subvention program in FY 1991- 92. The Assembly Way and Means Subcommittee recommends that the amount be reduced to $30 million, and it is very unsure that any funding will be provided in FY 1991-92. The Districts' primary collateral that the State claims will ultimately be paid is our possession of the Pine Creek Detention basin surplus property which can be sold to cover the State's subvention obligation on both the Wildcat-San Pablo Creeks project and the Walnut Creek project. On March 21, 1989, the Board of Supervisors considered the final report from the Wildcat and San Pablo Creeks Project Design Team (Design Team) which recommended a gabion-walled channel alternative on San Pablo Creek between the railroad tracks, the report from the Chief Engineer recommending implementation of the Corps approved plan alternative of a concrete channel lining, and letters stating preferences regarding channel lining type. The Board directed the Chief Engineer to solicit input from the Corps regarding timing, costs and flooding potential impacts due to implementation of each alternative. The Corps responded by letter indicating they had not programmed into their budget for 1990 sufficient funds to construct the channel improvements on San Pablo Creek between the railroad tracks. Consequently, the earliest this reach of channel could be improved is 1991. WILDCAT-SAN PABLO May 7, 1991 Page Three In response the Board on April 25, 1989 requested the Corps to consider the feasibility of a gabion-walled channel in this reach as a part of their hydraulic model study of Reach II (San Pablo Creek upstream of AT&SF.) On September 19, 1990 the Corps presented the results of their cost benefit analysis to the Design Team. Their analysis has concluded that a 100 year flood design for Reach II is not economically feasible and therefore a hydraulic model study is not warranted at this time. The Corps did perform a mathematical study and concluded that a gabion-walled channel between the tracks is hydraulically feasible for a portion of the portion of the reach between the tracks. After the Corps presented both the concrete-lined rectangular and gabion-walled channel alternatives, with their associated impacts, the Design Team accepted the concrete-lined rectangular channel. However, the acceptance was conditioned upon (1) the installation of an acceptable landscape mitigation corridor along the south bank of this reach and (2) the elimination of maintenance access from the top of bank and provision of access to the channel bottom at a location just downstream of the SPRR tracks. IV. Consequences of Negative Action: Completion of the two remaining segments of the Corps of Engineers improvements will not occur and $5,800,000 in State and Federal Government infrastructure funding will be lost.
