` �'� <br /> Under thc No Action altemative, thc Retuge would discontinuc on-going levec <br /> maintcnance and would not repair any Icvec breaks. The Rcfuge would work N�ith thc <br /> San Carlos Airport and the SBSA to protect tl�eir infrastructure on Inner Bair lsland. <br /> The existing levees on Middle and Outer Bair Island would eventually breach causing <br /> unmanaged tidal inundation of the ponds. This would result in several impacts to existing <br /> infrastructure. There would be an increase in the sedimentation rate of the Redwood <br /> Creek Shipping Channel resulting in the need for more frequent dredging by ihe Port of <br /> Redwood City. At least in the short-term, there would be an increase in the velocity rate <br /> of the tidal waters at the junction of Smith Slough and Redwood Creek making use of the <br /> Pete's Harbor Marina more difficult Ponding of water on Inner Bair Island would <br /> increase the bird strike issue for the San Cazlos Airport. Approximately 1,400 acres of <br /> tidal salt marsh would eventually be restored but the No Action Alternative would delay <br /> restoration of the ponds to salt marsh by 20-100 years and, at least in ihe short term, result <br /> in poorer quality endangered species habitat being developed compared to the four action <br /> alternatives. <br /> In the short-term (approximatel}� five years), the No Action altemative would provide <br /> limited public use consistent with protection of wildlife habitat and public safety. In the <br /> long term (approximately five to ten years), as the Inner Bair Island levee became unsafe, <br /> public use of the 3-mile trail would be eliminated and the area would be closed to public <br /> access. No additional public use infrastructure such as wildlife viewin� platforms and <br /> interpretive signage would be installed and the Bair Island parking lot would be closed. <br /> 7 <br />
