7C Page 41 C. Clapper Rail Potential Impact 8-3: Project construction would result in direct long-term loss of intertidal wetland along Redwood Creek sufficien# to support incidental foraging by the California clapper rail, a federal- and state-iisted endangered species. Noise from project constructian and project disturbance of intertidal habitat could interfere with the abiliijr 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 significarrt. These possible effects represent a pofentially signifrcant impact. Mitigation 8-3: The applicant shall: (1) cvordinate with the USFWS and CDFG on Cafifornia clapper rail issues; and (2)formulate and implement a Habitat MEtigation and Monitoring Plan (HMMP} for this patentialfy affected species to the satisfiaction of the t;SFVVS and CDFG. The HMMP shouid stipulate avoidance of construction operations during the Cafifornia clapper rail breeding seasan. To determine presence of breeding special-s#atus species in the project vicinity, USFWS-approved clapper rail surveys shouid be canducted during the breeding season, priar to construction. If breeding surveys detect clapper rail or other specia!-status bird species' breeding territories in adjacent wetlands, the US�VUS and CDFG sha4{ be consulted to determine if the distance of the terrifiory from fhe construction activiiy 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 C+ty shall not issue a grading permit for the project until the California clapper rail issues are resolved to the satisfactian of the USFWS and CDFG. Copies of written corresp�ndence 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-signi�canf level. D. Construction Impacts on Other Species Potentia[ Impact 8-4: Foraging and reproductive activities af wildfife in the adjacent sensitive habitat areas, including habitat of special-status species, cou[d be disrupted by projecf construction activity and noise. Noise impacts resulting from dredging, pile driving, and other co�struc#ion activities could disrupt reproductive s�ccess if conducted during the breading and nesting seasons of the following protected species: California clapper rai1, Caiifornia least tern, Western snowy plover, California biack raif, northern harrier, sho�t-eared owl, saftmarsh common yeilowthroat, and Aiameda song sparrow. These possible effec#s represent a potentially signrficant 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 Mifigation and Manitoring Plan (HMMP) for these potentially affected species to the satisfaction of the USFWS and CDFG. The HMMP shall stipulate avoidance of construction operatians during special-s#atus species' breeding seasan. To determine the presence of breeding special-status species in the project vicinity, US�WS and CDFG approved special-status species surveys shall be canducted dur�g 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 AttylReso/Reso.1772 20 121307
