other waterway unless a bermed and lined refueling area is constructed. o Vehicles shall be washed only at approved areas. No washing of vehicles shall occur at job sites. o To discourage the introduction and establishment of invasive plant species, seed mixtures/straw used within natural vegetation will be either rice straw or weed‐free straw. o Pipes, culverts and similar materials greater than four inches in diameter, will be stored so as to prevent covered wildlife species from using these as temporary refuges, and these materials will be inspected each morning for the presence of animals prior to being moved. o Erosion control measures will be implemented to reduce sedimentation in wetland habitat occupied by covered animal and plant species when activities are the source of potential erosion problems. Plastic mono‐filament netting (erosion control matting) or similar material containing netting shall not be used at the project. Acceptable substitutes include coconut coir matting or tackified hydroseeding compounds. o Stockpiling of material will occur such that direct effects to covered species are avoided. Stockpiling of material in riparian areas will occur outside of the top of bank, and preferably outside of the outer riparian dripline and will not exceed 30 days. o Grading will be restricted to the minimum area necessary. o Prior to ground disturbing activities in sensitive habitats, project construction boundaries and access areas will be flagged and temporarily fenced during construction to reduce the potential for vehicles and equipment to stray into adjacent habitats. o Significant earth moving‐activities will not be conducted in riparian areas within 24 hours of predicted storms or after major storms (defined as 1‐inch of rain or more). o Trenches will be backfilled as soon as possible. Open trenches will be searched each day prior to construction to ensure no covered species are trapped. Earthen escape ramps will be installed at intervals prescribed by a qualified biologist. • Species Specific Avoidance and Minimization Measures – The EACCS also includes species-specific AMMs. The species-specific AMMs for burrowing owls are described below. These measures are taken from Table 3-3 of the EACCS (ICF 2010). BIRD-2: Burrowing Owl o If an active nest is identified near a proposed work area work will be conducted outside of the nesting season (March 15 to September 1). o If an active nest is identified near a proposed work area and work cannot be conducted outside of the nesting season, a no‐activity zone will be established by a qualified biologist. The no‐activity zone will be large enough to avoid nest abandonment and will at a minimum be 250‐feet radius from the nest. This buffer is based on the recommended guidelines described in the “Staff Report on Burrowing Owl Mitigation” by the CDFW (2012). o If burrowing owls are present at the site during the non‐breeding period, a qualified biologist will establish a no‐activity zone of at least 150 feet. o If an effective no‐activity zone cannot be established in either case, an experienced burrowing owl biologist will develop a site‐specific plan (i.e., a plan that considers the type and extent of the proposed activity, the duration and timing of the activity, the sensitivity and habituation of theowls, and the dissimilarity of the proposed activity with background activities) to minimize the potential to affect the reproductive success of the owls.
