. JULY 2011 THE BELMONT CREEK CHANNEL MAINTENANCE PROJECT— <br /> � HABITAT MITIGATION AND MONITORING PLAN <br /> D. Location of Project and Associated Mitigation Site <br /> The proposed Maintenance Project site is located parallel to Old County Road just southeast of <br /> Harbor Boulevazd, in unincorporated San Mateo County. The associated Mitigation Site is <br /> located on the southwest bank of Belmont Creek adjacent to the City of Belmont's <br /> Corporation Yazd located at 110 Sem Lane, Belmont, California, 94002. The Mitigation Site <br /> is approximately 0.4 stream miles downstream of the Highway 101 crossing and is located <br /> adjacent to and opposite of recreational bay trails. The Mitigation Site is located within the <br /> City of Redwood City, San Mateo County, California (See Figures 1 through 3). <br /> E. Brief Summary of Overall Project <br /> The Maintenance Project consists of an approxunately 240-foot long segment of Belmont <br /> Creek within the County maintained road right-of-way. The purpose of the Maintenance <br /> Project is to improve flood flow capacity through vegetation and sediment management by <br /> removing approxunately 47 cubic yards of accumulated sediment and aquatic vegetation <br /> from the channel bottom, bank repair, as well as trimming the willows overhanging the <br /> creek. <br /> Belmont Creek originates in rural residential hills within the City of Belmont, and flows <br /> through low- to medium-density residential azeas, often through an underground culvert <br /> system, and daylights just upstream of the Harbor/Industrial unincorporated area of San <br /> Mateo County (see Figure 2). Belmont Creek enters San Francisco Bay approximately 3.7 <br /> miles downstream from the Maintenance Project site. <br /> To satisfy requirements set forth by the Regional Board, the Maintenance Project impacts will be <br /> mitigated through the planting of ten coast live oak trees (Quercus agrifolia) and the removal of <br /> invasive nonnative vegetation, primarily sweet fennel (Foenicu[um vulgare), as detailed in this <br /> fIIvfMP. <br /> II. GOAL OF MITIGATION <br /> The goal of this HMMP is to enhance upland creekside habitat as mitigation for the 1600 squaze-feet <br /> (0.036 acres) of aquatic vegetation temporarily unpacted by maintenance activities. Impacted <br /> vegetation includes common horsetail (Equisetum arvense), watercress (Nasturtium o�cinale), <br /> F:\users\u[ility\warershed�rorection�PERM[TS\WPS2010-009 Belmont Creek Channel <br /> Maintenance\Sediment Removal�Regional Board\Mitigation�Belmont_HMMP.docx - 2 - <br />
