the detailed design phase of the project is mandatory. (see Page 61, Section 4.5.4.1 for a full list of source control measures included in this mitigation measure) Finding: Implementation of Mitigation BIO-3.1 would reduce the project-related impact of increased sedimentation and stormwater pollutants impacting special status fish species to a less than significant level. Facts in Support of Finding: This mitigation measure is consistent with best management practice to reduce pollution generation, discharge, and runoff. The standards are sanctioned at the national and regional level. Impact: BIO-4: Due to the rarity of salt marsh harvest mice and salt marsh wandering shrews, any loss of use of suitable habitat or increase in predation of these species as a result of an increase in lighting would be a significant impact. Mitigation: BIO4-1: Prior to initiation of any construction activities, a qualified biologist shall teach a training session for all construction personnel. At a minimum, the training shall include descriptions of the salt marsh harvest mouse and salt marsh wandering shrew, their habitats, the laws protecting them, the general measures that are being implemented to conserve these species as they relate to the project, and the boundaries within which the project may be accomplished. BIO-4.2: Prior to the start of project activities below the top of levee, herbaceous vegetation shall be removed from impact areas to eliminate cover for salt marsh harvest mice and salt marsh wandering shrews. Vegetation removal shall start where the transitional habitat intersects the Bay Trail and shall continue northwards towards the open marsh habitat. Vegetation shall not be removed during a high tide or king tide event that temporarily inundates Belmont Slough. A qualified biologist shall complete a pre-construction survey prior to vegetation removal and shall monitor the vegetation removal process. Vegetation shall be removed using hand-held equipment (e.g., weed-whackers). All herbaceous vegetation that could potentially conceal a salt marsh harvest mouse or salt marsh wandering shrew within the project impact area shall be removed. All vegetation that is removed shall be hauled off-site the day it is removed and shall not be left on the site to provide potential cover for small mammal species. The area of vegetation removal shall extend a short distance beyond the boundary of the work area in Belmont Slough to create an open area that shall discourage salt marsh harvest mice and salt marsh wandering shrews from approaching the exclusion barrier(addressed in MM BIO-4.3). BIO-4.3: After removal of the vegetation and prior to the start of construction activities within Belmont Slough, a barrier shall be installed at the outer limits of the work area within and along Belmont Slough to stop salt marsh harvest mice and salt marsh wandering shrews from entering the project site. The barrier, which shall be shown on the project plans and shall be constructed under the guidance of a qualified biologist, shall consist of a three-foot tall, tight cloth, smooth plastic, or sheet-metal (or similar material approved by the USFWS) fence toed into the soil at least three inches deep and supported with stakes placed on the inside of the barrier. A qualified biologist shall complete a pre- construction survey of the area where vegetation was removed prior to ATTY/RES0.0036/PC RESO CERTIFYING EIR—ORACLE DESIGN TECH HIGH SCHOOL REV:04-29-16 VR Page 7 of 31
