Accept the following recommendation from the San Ramon Valley Regional Planning Commission: Deny the General Plan Amendment request (GP 96-0012) , the Rezoning request (RZ 96-3037) and the Preliminary and Final Development Plan (DP 96-3004) . Alternatively, the Board may wish to continue these matters to be considered with the appeal of the Planning Commission conditional approval of Subdivision #968002 on November 19, 1996. FISCAL IMPACT None BACKGROUND/REASONS FOR RECOMMENDATIONS Commission Recommendations : The County Planning Commission and the San Ramon Valley Regional Planning Commission held joint hearings on this project. The County Planning Commission recommends the approval of the project with conditions as modified. The attached conditions include the modifications of the County Planning Commission in an annotated format. The San Ramon Valley Regional Planning Commission unanimously voted to recommend that the Board deny the General Plan Amendment and the related project entitlements . The San Ramon Valley Regional Planning Commission felt that the approval of the project' was premature in that the property is not contiguous to lands either developed or planned for development and that the subdivision improvements proposed were inappropriate for the site. Water Quality Issues : During the public hearings on the project, several issues were raised regarding water quality and the mitigation of water quality impacts. The County Public Works Department has provided additional information regarding these issues . The developer has proposed to incorporate a basin for mitigating water quality and water quantity impacts. The incorporation of wetlands or a biofilter can be part of a greater water quantity or peak reduction basin. However, there is a nexus between the time the storage volume is retained and the percent suspended solids remaining in the runoff. Typical standards for detention basins require that the basin drain in 24 hours in preparation for the next storm. A water quality basin requires greater storage time of between 48 and 96 hours to effectively reduce or eliminate the increased turbidity due to the suspension of solids like soil and vegetative debris . This additional storage period requires a larger basin and therefore requires significantly more land area. The high value of developable land in Contra Costa County measured against the diminishing returns of Board Order November 12, 1996 Page 3 retaining the water more than 24 hours have to be weighed against each other. There may be additional, less expensive measures that would also provide some redundancy in protection that could be incorporated at a significantly lower capital cost. This redundancy provides several benefits in reducing the impacts of urbanization on storm water quality. A single measure has no protection against failure. The measure either works or doesn' t, and when it doesn' t there is no other protection against the impacts on storm water quality. A single measure is often very costly, and in the case of the aforementioned basin, may not provide the same possibilities for education and recreation several measures would afford. One of the concerns raised regarding the introduction of wetlands into a detention basin, is that due to current regulatory restrictions, the basin would become unmaintainable. Once wetlands establish themselves in a detention basin, the regulatory process necessary to remove the vegetation during desilting of the basin becomes very arduous . The sediments settling within the basin would degrade the flood protection historically provided. In answer to this concern, the California Regional Water Quality Control Board (RWQCB) has adopted an understanding with other regulatory agencies that wetlands introduced for water quality benefit would not need the usual regulatory permits . There has been no test of this policy to date, and the risk still exists that the introduction of wetland vegetation could also foster the growth of endangered species . Then truly, the basin would no longer be maintainable. Consequently, a tiered basin that separates detention/storage from water quality areas clearly makes more sense, so that the detention portion of the basin can be consistently maintained without the fear of heightened regulatory interest. By incorporating several mitigation measures, the measures can be small, integral features of the development that in and of themselves provide a natural amenity to the looks of the subdivision. Staff would advocate that the developer provide a more complete plan to mitigate storm water pollution which provides a well-rounded approach and includes certain redundancies . Another issue considered as part of the storm water pollution program is that of performance standards. To date, local municipalities have tried to keep the RWQCB from developing the same standards in the hope that the work necessary would not be beyond the resource and expertise of the local municipality. Requirements could be as simple as street sweeping or as onerous as treatment of storm water much like our current sewer system. Therefore, local governments have advocated measures that reduce storm water pollution to the maximum extent practicable. This more "reasonable" standard interjects a common sense approach into the decision making on individual measure (s) . However, it is important to note that only by very gross standards is money a reasonable excuse for rejecting an individual measure. The measure is more likely to be rejected because of the return on investment. If a measure is very expensive for the effectiveness standard it meets, several other measures may be advocated in its place with significantly better results. Several concerns regarding the Siu Family pond have been raised and all of the issues should be addressed in further study. The dam should be analyzed for its integrity for Board Order November 12, 1996 Page 4 longer saturation periods as the peak is extended. In addition, the development of a passive means of insuring that the Siu pond has some protection against the first storm • carrying most of the pollutants and the possible failure of the sewage pumping plant should be incorporated into the design of the project. It is anticipated that the potential impacts to the Siu pond can be mitigated. The Public Works Department recommends that all of the issues alliterated here be resolved prior to the filing of the first final map or by July 1, 1997 whichever comes first.
