12/17/2007 C. Clapper Rail Potential Impact 8-3: Project construction would result in direct long-term loss of intertidal wetland along Redwood Creek sufficient to support incidental foraging by the California clapper rail, a federal- and state-listed endangered species. Noise from project construction and project disturbance of intertidal habitat could interfere with the ability of the clapper rails to detect predators. Impacts on clapper rails from noise associated with pile driving, heavy construction, and earthmoving equipment in particular are potentially significant. These possible effects represent a potentially significant impact. Mitigation 8-3: The applicant shall: (1) coordinate with the USFWS and CDFG on California clapper rail issues; and (2) formulate and implement a Habitat Mitigation and Monitoring Plan (HMMP) for this potentially affected species to the satisfaction of the USFWS and CDFG. The HMMP should stipulate avoidance of construction operations during the California clapper rail breeding season. To determine presence of breeding special-status species in the project vicinity, USFWS-approved clapper rail surveys should be conducted during the breeding season, prior to construction. If breeding surveys detect clapper rail or other special-status bird species' breeding territories in adjacent wetlands, the USFWS and CDFG shall be consulted to determine if the distance of the territory from the construction activity is a suitable buffer requiring no further action. If breeding territories are found to be potentially affected by construction-related noise, all construction activities should be prohibited within the buffer area as specified by the USFWS and/or CDFG. The City of Redwood City shall not issue a grading permit for the project until the California clapper rail issues are resolved to the satisfaction of the USFWS and CDFG. Copies of written correspondence between USFWS and CDFG and the applicant shall be submitted to the City prior to issuance of a grading permit. Findings: Implementation of these measures is feasible and would reduce this potential impact to a less-than-significant level. D. Construction Impacts on Other Species Potential Impact 8-4: Foraging and reproductive activities of wildlife in the adjacent sensitive habitat areas, including habitat of special-status species, could be disrupted by project construction activity and noise. Noise impacts resulting from dredging, pile driving, and other construction activities could disrupt reproductive success if conducted during the breeding and nesting seasons of the following protected species: California clapper rail, California least tern, Western snowy plover, California black rail, northern harrier, short-eared owl, saltmarsh common yellowthroat, and Alameda song sparrow. These possible effects represent a potentially significant impact. Mitigation 8-4: The applicant shall: (1) coordinate with the USFWS and CDFG on noise issues related to special-status species in the adjacent sensitive habitats; and (2) formulate and implement an associated Habitat Mitigation and Monitoring Plan (HMMP) for these potentially affected species to the satisfaction of the USFWS and CDFG. The HMMP shall stipulate avoidance of construction operations during special-status species' breeding season. To determine the presence of breeding special-status species in the project vicinity, USFWS and CDFG approved special-status species surveys shall be conducted during the breeding season, prior to construction. If breeding surveys detect special status species' breeding territories in adjacent wetlands, the USFWS and CDFG shall be consulted to Atty/Reso/Reso.1772 121707 20 14829 Muff# 613
