c. A DFG Streambed Alteration Agreement and 401 Water Quality Certification may also be required for fill of the irrigation canals and the ephemeral (College)drainage. DFG shall be consulted to determine if a Streambed Alteration Agreement is required. If USACE does not take jurisdiction over the irrigation canals or drainages, the RWQCB shall be consulted to determine if a 401 Water Quality Certification is required. d. The acreage of waters of the United States that would be removed shall be replaced or restored/enhanced by the developers on a "no-net-loss" basis in accordance with USACE and DFG regulations. Habitat restoration, enhancement, or replacement shall be at a location and by methods agreeable to USACE and DFG, as determined during the CWA Section 404 and California Fish and Game Code Section 1602 permitting processes. [MM4.10-10] Timing: The applicant shall submit an approved report of pre-construction surveys to the San Joaquin County Community Development Department(CDD)prior to the issuance of grading permits for the project. 42. Biological Resources Efects from Offsite Infrastructure Improvements: San Joaquin Countv For those off-site improvements proposed in San Joaquin County, the College Park developers shall implement Mitigation Measures 4.10-5, 4.10-6,4.10-7, 4.10-9, and 4.10-10. Alameda County For those off-site improvements proposed in Alameda County, the College Park developers shall implement the measures identified below: Special-Status Plants a. Before any ground-disturbing or vegetation-clearing activities, a qualified botanist shall conduct surveys for the special-status plant species identified in Table 4.10-1 of the College Park Final EIR. Surveys shall be conducted at the appropriate time,when the target species would be in flower and therefore clearly identifiable(i.e., blooming period) and in all areas of suitable habitat that would potentially be disturbed. If no special-status plants are found, no further mitigation shall be required. b. If special-status plants are found and the populations can be avoided during project implementation, they shall be clearly marked in the field by a qualified botanist for avoidance during construction activities c. If special-status plant populations cannot be avoided, consultations with DFG and/or USFWS may be required, depending on the listing status of the species present. These consultations shall determine appropriate mitigation measures for any populations that would be affected by the implementation of the proposed project.Appropriate measures may include the creation of off-site populations through seed collection or transplanting, preservation and enhancement of existing populations, or restoration or creation of suitable habitat in sufficient quantities to compensate for the impact. California Red-Legged Frog a. Before project activity, USFWS shall be consulted to determine whether widening of Grant Line Road has potential to adversely affect California red-legged frog. It may be necessary to conduct a formal habitat assessment and surveys to make such a determination. If it is determined that adverse effects are unlikely to occur, no further mitigation shall be required. b. If it is determined that adverse effects to California red-legged frog could occur, consultation with USFWS shall be conducted, and authorization for incidental take could be required. Speck mitigation measures would be developed during the consultation process. Measures designed to avoid and minimize take to the greatest extent feasible shall be developed and implemented. These may include limiting activities to certain seasons, minimizing vegetation removal and in-water construction activities, conducting pre-construction surveys, and conducting daily surveys and monitoring of construction areas. If necessary, appropriate compensation for loss of habitat and other adverse 12
