M A S T E R P L A N F O R L W D P <br /> CREEK AND DRAINAGE SWALE <br /> Both parks include reaches of Kottinger Creek, each with very different character, <br /> which receive different treatment recommendations by this Master Plan. Both reaches <br /> are classified as Waters of the U.S. by the Army Corps of Engineers, and are <br /> under jurisdictional oversight and regulation by numerous agencies, including Army <br /> Corps of Engineers, California Department of Fish and Wildlife, the United States <br /> Fish and Wildlife Service, and the Bay Area Regional Water Quality Control Board <br /> (see Appendix A). Any changes proposed within the creek itself or within its <br /> regulation-defined zone require approvals and permits from these agencies. The <br /> process to obtain official permissions has been initiated by the City with a Preliminary <br /> Jurisdictional Determination (PJD), a report filed with the Army Corps of Engineers, <br /> as well as initiating correspondence with other agencies. At this time, it is expected <br /> that any mitigation requirements will be implemented of site. <br /> Currently, on both sides of Neal Street, visibility into the channel is severely <br /> limited by the depth of each channel. Where no water is present, this presents <br /> significant safety concerns, and where water is present, it creates a clear and objective <br /> safety hazard. The drainage swale within Lions Wayside Park is dry most of the year, <br /> and contains few or no wetland plants or soils. The creek within Delucchi Park has <br /> water present all year-round, as well as wetland plants and soil-types. <br /> In Lions Wayside Park, between the Chan Henderson Bandstand and the <br /> Firehouse Arts Center, the drainage swale bisects the park. In Delucchi Park, the creek <br /> forms the western edge of the usable park, and separates the park area from its <br /> parking lot and the adjacent downtown commercial development. <br /> In 2002, the DPTS recommended: "... the Master Plan recommends covering the <br /> drainage swale in and adjacent to Lions Wayside Park. (It bisects the proposed park <br /> area, is difficult to see into and to maintain, and no longer carries water from nearby <br /> storm sewers.)" Although most water has been controlled by upstream development <br /> and impoundments, occasional flows occur in the park during extended or intense <br /> rain events. <br /> RECOMMENDATIONS <br /> 18 <br />
