City of Santa Ana California Environmental Quality Act Initial Study/Mitigated Negative Declaration f) The Project will not conflict with any adopted conservation plan. The proposed Project will comply with the City's Tree Preservation Ordinance and Urban Forestry Plan. The Project aligns with the City's General Plan Conservation Element Goals CN-2 (enhancing natural and environmental resources while maintaining a balance between recreation, habitat restoration, and scenic resources), and CN-4 (conserving and replenishing existing and future water resources). Mitigation Measures: BI0-1— Prior to ground -disturbing activities in areas that could support sensitive biological resources, a habitat assessment shall be conducted by a qualified biologist to determine the potential for special - status wildlife species to occur within affected areas, including areas directly or indirectly impacted by construction or operation of the Project. If a special -status wildlife species is found, pre -construction surveys of proposed work zones should be conducted 14 days prior to construction. Areas including construction areas, staging areas, and rights -of -way, should be staked, flagged, fenced, or otherwise clearly delineated to restrict the limits of construction to the minimum necessary near areas that may support special -status wildlife species with special -status wildlife species; if avoidance is not possible, the City of Santa Ana should consult with the appropriate regulating agency (USACE/USFWS/CDFW) to determine a strategy for compliance with the Endangered Species Act, California Fish and Wildlife Code, or other regulations supporting special -status species. The City of Santa Ana will work together with those regulating agencies to determine appropriate impact minimization measures and compensation for any permanent impacts due to the Project. If no breeding and nesting birds and/or raptors are found, then construction may proceed as scheduled with no additional monitoring or measured required. BIO-2 — To protect nesting birds that may occur on site or adjacent to the Project boundary, no construction shall occur from February 1 through September 15, as early as January 1 for some raptors, unless a qualified biologist completes a survey for nesting bird activity within a 500-foot radius of the construction site. The nesting bird surveys shall be conducted at appropriate nesting times and concentrate on potential roosting or perch sites. The City of Santa Ana should require surveys be conducted by a qualified biologist no more than 7 days prior to the beginning of any Project -related activity likely to impact raptors and migratory songbirds, for the entire Project site. If Project activities are delayed or suspended for more than 7 days during the breeding season, the surveys shall be repeated. If nesting raptors and migratory songbirds are identified, the following minimum no - disturbance buffers shall be implemented: 300 feet around active passerine (perching birds and songbirds) nests, 500 feet around active non -listed raptor nests and 0.5 mile around active listed bird nests. These buffers shall be maintained until the breeding season has ended or until a qualified biologist has determined that the birds have fledged and are no longer reliant upon the nest or parental care for survival. Any sensitive and special status species data documented by the Project shall be submitted to the California Natural Diversity Database with all applicable data fields filled out. The City of Santa Ana and/or a designee will notify the CDFW once submitted. BI0-3 — The Project shall implement BMPs to prevent erosion and the discharge of sediment and pollutants into drainages during Project activities. BMPs shall be monitored and repaired, if necessary, to ensure maximum erosion, sediment, and pollution control. The Project proponent shall prohibit the use of erosion control materials potentially harmful to fish and wildlife species, such as mono -filament netting (erosion control matting) or similar material. All fiber rolls, straw wattles, and/or hay bales utilized within and adjacent to the Project site shall be free of nonnative plant materials. Fiber rolls or erosion control mesh shall be made of loose -weave mesh that is not fused at the intersections of the weave, such as jute, or coconut (coir) fiber, or other products without welded weaves. -16CWE7 -
