Title

2017 Storm Damage DWR Rehabilitation - Phase 4 and 5 Repair Sites

Description

DWR implemented the 2017 Storm Damage DWR Emergency Rehabilitation Program for emergency repair sites in Phases 1 through 3 in 2017 and 2018. The purpose of the proposed project in this IS/MND is to address additional non-emergency sites (Phases 4 and 5) identified for repair in 2019/2020. The previous emergency repairs under Phases 1 through 3 did not require CEQA because those sites met the Statutory Exemption under the CEQA Guidelines Section 15269 criteria for emergency projects that are necessary to maintain levee structures essential to public health, safety and welfare due to the potential for levee failures without the repairs during the 2017/2018 phases. The proposed project includes a total of 30 repair sites located in Yolo, Sutter, Tehama, Butte, Colusa, Glenn, San Joaquin, and Sacramento counties. The proposed project would repair and rehabilitate levees at the 30 locations using a variety of construction equipment, requiring different design considerations based on levee conditions. The repair and rehabilitation would be scheduled to occur within a permitted time period to avoid impacts on special-status species and wet weather conditions. Construction activities would take place at each site throughout the summer/fall of 20'19 or 2020 (from July 2 through November 1). Each levee sue would require approximately 2 to 4 weeks of active construction. All work would take place during daylight hours, and no nighttime lighting would be required. The maximum length of the work day would be 5 a.m. to 8 p.m. depending on allowable daylight Noise ordinances would be followed for sites located in residential areas. At least three sites would be repaired concurrently, with up to nine sites being repaired at the same time, based on limitations of hauling, air quality permitting, and other potential permit restrictions by responsible agencies. DWR has incorporated environmental commitments into the proposed project that include conservation measures and/or best management practices developed in coordination with the responsible resources agencies to avoid, minimize and/or provide compensation for effects on biological resources. DWR would implement these environmental commitments as part of the proposed project construction activities. These commitments would be satisfied even if not separately imposed by permitting agencies and, if permitting agencies impose additional measures or modifications, those would also be adhered to as part of the permit(s).
