Page 4.C-54    BCC-130 [See page 5-189 for the original comment] REVISE Mitigation Measure 4.C-2a to read as follows:

Mitigation Measure 4.C-2a: The applicant shall avoid or minimize adverse effects on sensitive natural communities and restored wetland mitigation areas created to comply with remediation permit requirements or any restored habitat that may have been created as part of site clean-up actions. After Project Site remediation has concluded, measures shall be implemented to avoid impacts to sensitive natural communities or restored habitat areas, including the installation of silt fencing, straw wattles, or other appropriate erosion and sediment control methods or devices to prevent runoff and construction debris from entering these areas. Such measures shall also be employed where pre-construction grading and post- remediation development may require work adjacent to sensitive natural communities, either prior to or after restoration of those areas occurs.

Where construction activities occur in the vicinity of sensitive natural communities onsite, the following shall be implemented to ensure no loss of restored mitigation sites:

• Fencing shall be erected adjacent to the areas where construction is occurring to avoid unintended impacts to sensitive natural area that occur just outside the construction area, and shall be constructed in a manner that will not impede wildlife access to wetland areas. Construction workers will be educated about local resources and instructed to avoid sensitive habitats during construction including limiting any human intrusion into natural areas.

 

• If work in the vicinity of natural communities cannot be avoided, work within these areas shall be conducted during the dry season, typically between May 1 and October 15, and shall occur under permit authority of CDFW, Corps and RWQCB pursuant to the CWA Section 404 requirements for avoidance, mitigation and monitoring. Mitigation Measures 4.2-2b and 4.C-2c shall also apply if work cannot be avoided in or directly adjacent to sensitive natural areas or restored habitats created as part of site cleanup actions.

Page 4.C-51    Master Response 9 - REVISE Mitigation Measure 4.C-2c to read as follows:

Mitigation Measure 4.C-2c: Where disturbance to sensitive natural communities cannot be avoided, compensation shall be provided for temporary impacts and permanent loss to ensure that there is no overall loss of sensitive natural communities as a result of Project Site development.

Onsite, in kind replacement of sensitive natural communities including coastal scrub, willow scrub, tidal marsh, freshwater emergent wetlands, and lined manmade drainages that have developed bed and bank characteristics shall be a condition of development. Compensation shall be detailed on an impact-specific basis and shall include development of an onsite wetland mitigation and monitoring plan, which shall be developed prior to Project Site development or in coordination with permit applications and/or
