LEVEL OF SIGNIFICANCE AFTER MITIGATION. This impact remains significant after application of all feasible mitigation.
LEVEL OF SIGNIFICANCE AFTER MITIGATION. With the mitigation described above, this impact is reduced to a less than significant level. Impact: Finding(s): (1) Changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the significant environmental effect as identified in the PEIR. of silt curtains, operational controls, and water quality monitoring. The measures also require the inclusion and implementation of a Dredging Management Plan (DMP) for the Project, which will assist in preventing accidental spills and providing the necessary guidelines to follow in case of an oil or fuel spill, and is expected reduce the potential for a significant long-term impact to special-status fish species. Refer to Mitigation Measures 4.2.1, 4.2.2, 4.2.3, 4.2.4, 4.2.5, 4.2.6, and 4.2.9 under CEQA Finding No. WQ 4.2.6.
LEVEL OF SIGNIFICANCE AFTER MITIGATION. If any mitigation measures are required and implemented, the potentially significant impacts will be mitigated to a level of insignificance.
LEVEL OF SIGNIFICANCE AFTER MITIGATION. With the mitigation described above, this impact is reduced to a less than significant level. Impact: Finding(s): (1) Changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the significant environmental effect as identified in the EIR. Petroleum-fueled construction equipment will be used to complete the proposed activities. The potential exists for leakage/spills from in-water dredging or from improper fueling or hazardous materials storage practices. A petroleum spill could result in potentially significantly impacts to water quality and to the marine biota within the project site and region. The following mitigation measure, which requires implementation of measures pursuant to a National Pollutant Discharge Elimination System (NPDES) issued by the Central Coast RWQCB, which has jurisdiction over water quality issues in the Project area, will be implemented to reduce the impacts to less than significant. Mitigation Measure WQ‐2. Acquire and comply with the project‐specific NPDES permit for the discharge of dredge‐generated and other authorized discharges.

Impact: Finding(s): (1) Changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the significant environmental effect as identified in the EIR/EIS. FACTS SUPPORTING THE FINDING(S) Dredging of the Connector Channel and construction of the breaches could result in elevated turbidity in the vicinity of the dredging operations. This impact will be mitigated by Mitigation Measure WQ-MM-3, which requires compliance with applicable water quality permits. Implementation of WQ-MM-3 has been incorporated into the Project to reduce this impact to a less-than-significant level. SLT and its contractors shall ensure to the extent practicable that the turbidity (as measured in Nephelometric Turbidity Units [NTUs]) shall not exceed background levels by more than the 10 percent outside the Project Boundary when background levels are greater than or equal to 50 NTU, to the extent practicable. The Project Boundary for the dredged areas is to be defined by a silt curtain to be required by SLT of its contractors. In the event a silt curtain is not used to control turbidity, the Project Boundary shall be defined as the daily limit of dredging or excavation of breaches and connections in any area where such work occurs. If turbidity does increase above the exceedance level, SLT shall follow remedial measures required by RWQCB. LEVEL OF SIGNIFICANCE AFTER MITIGATION.

LEVEL OF SIGNIFICANCE AFTER MITIGATION. With the mitigation described above, this impact is reduced to a less than significant level. Impact: Finding(s): (1) Changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the significant environmental effect as identified in the EIR/EIS. FACTS SUPPORTING THE FINDING(S) California xxxxxxx rails and California black rails could be harmed or suffer disturbance as a result of construction activities in tidal xxxxx habitat. This impact will be mitigated through the implementation of Mitigation Measure BIO-MM-5 that requires that disturbance to California xxxxxxx rail and Black rail habitat be avoided during their breeding period or by complying with USFWS protocols to identify the location of rails and maintain setbacks from breeding xxxxxxx rails. Implementation of BIO-MM-5 has been incorporated into the Project to reduce this impact to a less-than-significant level. • To minimize or avoid the loss of individual rails, activities within or adjacent to tidal xxxxx areas will be avoided during the rail breeding season from February 1 through August 31 each year unless surveys are conducted to determine if rail locations and rail territories can be avoided, or the xxxxx is determined to be unsuitable rail breeding habitat by a qualified biologist. • If breeding rails are determined to be present, activities will not occur within 700 feet, or greater, if a biologist determines potential impacts. If the intervening distance across a major slough channel or across a substantial barrier between the xxxxxxx rail calling center and any activity area is greater than 200 feet, then it may proceed at that location within the breeding season if a biologist determines the distance is sufficient and there are no impacts on rail behavior. • If rails are located, Sonoma Land Trust shall consult with USFWS and the California Department of Fish and Wildlife to determine what, if any, additional mitigation measures may be required to allow construction to proceed.

LEVEL OF SIGNIFICANCE AFTER MITIGATION. With the mitigation described above, this impact is reduced to a less than significant level. Impact: Finding(s): (1) Changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the significant environmental effect as identified in the EIR/EIS. FACTS SUPPORTING THE FINDING(S) The process of dredging material from the Connector Channel may disturb and redistribute contaminants that have been previously buried or otherwise sequestered in sediments. Once disturbed, these contaminants may become biologically available in sediments and the water column and could exert toxic effects on organisms that come in contact with them. Materials that are reused on-site could also come into contact with the water column or biota once the site is breached. This impact will be mitigated by Mitigation Measure HAZ-MM-4, which requires dredged material sampling and reuse/disposal in accordance with requirements set forth by the Dredged Materials Management Office. Implementation of HAZ-MM-4 has been incorporated into the Project to reduce this impact to a less-than-significant level. • Sonoma Land Trust shall sample and test sediments proposed to be dredged for chemical constituents of concern and for toxicity using protocols acceptable to the San Francisco Dredged Material Management Office (DMMO). • The DMMO will evaluate the adequacy of the sampling and testing and the acceptability of the dredged material for reuse at proposed sites in the restoration area for beneficial reuse as either wetland foundation or surface material.
