City of Santa Ana Chapter 3. Environmental Impact Analysis results of the preconstruction nesting bird survey will be provided to the City of Santa Ana Planning Manager, prior to issuance of grading permits. Mitigation Measure T3T0.4: Prior to issuance of grading and building permits, the project applicant will retain a qualified biologist to prepare a wetland mitigation plan, The mitigation plan will be subject to the approval of the Santa Ana 4` QGB Regional Water Quality Control Board. The mitigation plan will include measures to mitigate the loss of 0;021 acre of wetland, which may include creation of new wetland areas or enhancement of existing wetland or non - wetland jurisdictional waters at minimum 2:1 ratio. Creation or enhancement maybe conducted through an approved in -lieu fee program, such as those provided by the Santa Ana Watershed Association, The applicant will process requests foe applicable permits from the appropriate jurisdictional agencies. All permit requirements and conditions of permit approval will be implemented as part of the project. 3.2.3 Geology and Soils The Met TS /MND found that the previous project would result in less - than - significant impacts after implementation of mitigation related to seismic ground shaking, seismic - related ground failure, unstable soils, and expansive soils. No impacts or less - than - significant Impacts were found to occur related to earthquake fault rupture, landslides, erosion, and septic tanks, The major geologic constraints on the project site Include its location within a seismically active region and fairly close to several major active faults, and its susceptibility to ground failure as a result of liquefaction and unstable and expansive soils. Changes to project features, such as increasing the total number of acres developed and buildings' constructed and decreasing the amount of grading required, would not increase the severity of these impacts. Furthermore, the proposed project would be required to implement all mitigation measures as proposed in The Met IS /MND, which are listed below. No additional or new significant impacts that were not previously addressed in The Met IS /MND have been identified, and the proposed project would not represent a substantial change from the previous conclusions in The Met IS /MND. Applicable Mitigation Measures Mitigation Measure G130 -1: Prior to the issuance of grading or building permits, a design -level geotechnical investigation will be prepared by the project applicant and submitted to the City of Santa Ana Planning and Building Agency for review and confirmation that the proposed development fully complies with the California Building Code. The report will address potential seismic hazards such as groundshaking and liquefaction. The report will identify building techniques appropriate to minimize seismic damage. All design criteria and specifications set forth In the geotechnical report will be implemented as a condition of project approval. At a minimum, the design level geotechnical report will include the following: • Project design capable of withstanding seismic hazards associated with sarong ground motions, liquefaction, seismicaliy induced settlement, and expansive soils. • Earthwork procedures to address subsurface conditions (e.g., high groundwater conditions, soil composition, expansive and corrosive soils) including removal, moisture conditioning, and compaction.
