JULY 20ll THE BELMONT CREEK CHANNEL MAINTENANCE PROJECT— <br /> � HABITAT MITIGATION AND MONITORING PLAN <br /> and cattails (Typha sp.) within the Belmont Creek channel, and is expected to grow back by <br /> spring 2012. <br /> III. FINAL SUCCESS CRITERIA <br /> To mitigate for the temporary loss of vegetation, ten coast live oak trees will be planted along a <br /> section of Belmont Creek above ordinary high water. Success of the Mitigation Plan will be <br /> based on 100% coast live oak survival� rate. Coast live oak is an evergreen tree, native to <br /> California, with a typical lifespan of 40 to 110 yeazs. Coast live oak matures at 20 years with a <br /> typical crown diameter of 20 feet. At maturity, the vegetation coverage is expected Yo reach <br /> approximately 3,200 square-feet (0.073 acres), fulfilling the 2:1 vegetation replacement ratio as <br /> required by the Regional Board. The trees will provide nesting and foraging habitat for <br /> migratory birds and small maminals and will improve aesthetic quality along adjacent <br /> recreational trails (USDA, 2009). <br /> IV. MITIGATION SITE <br /> A. Size and Existing Conditions of Mitigation Site <br /> The planned Mitigation Site is approximately 35-feet wide and 200-feet long (0.16 acres), <br /> and is located on an upland levee adjacent to Belmont Creek (See Figure 3). Current site <br /> conditions consist of upland invasive weeds such as sweet fennel (Foeniculum vulgare) and <br /> unidentified non-native grasses. Patches of sea fig (Carpobrotus sp.) aze present along the <br /> bank. The creek channel is tidal at this point and is dominated by pickleweed (Salicornia <br /> virginica) and invasive cordgrass (Spartina spp.) <br /> B. Ownership Status <br /> The City of Redwood City is.the owner of the Mitigation Site. <br /> V. IMPLEMENTATION PLAN <br /> A. Planting Plan <br /> 1.
