2. Project Description <br /> <br />San Leandro Treatment Wetland <br />IS/MND <br />2-15 February 2024 <br /> <br />2.4. Project Construction <br />Schedule and Workforce <br />The active construction phase of the Project is estimated to occur over four to five months during two dry <br />seasons of 2024 and 2025, as outlined in Table 2-1. Construction operations are anticipated to be <br />predominantly scheduled on weekdays, from Monday through Friday, with operational hours from 7:00 a.m. to <br />5:00 p.m. Occasional work outside of these standard hours may be necessary, particularly for tasks such as <br />integrating new facilities with existing processes. Construction crews would be comprised of ten to fifteen <br />personnel. Parking would be available in the staging areas described below. <br />Table 2-1. Approximate Construction Schedule <br />CONSTRUCTION PHASE AND ACTIVITY EXPECTED DURATION ESTIMATED SCHEDULE <br />1) Pond dewatering, soil relocation/placement, import soil <br />placement, and compaction <br />Four to six weeks August 2024 <br />2) Nitrification system installation Six to eight weeks June 2025 <br />3) Liner installation, hydraulic distribution installation, slopes & <br />dikes <br />Four weeks, concurrent <br />with Phase 2 <br />June-July 2025 <br />4) Outfall Retrofit Two weeks (concurrent with <br />Phase 3) <br />Sep 2025 <br />5) Site Restoration and planting Two weeks Oct 2025 <br />Construction Equipment <br />The following construction equipment would be used during Project construction: <br />• Loader <br />• Trucks/Trailers <br />• Skid steer <br />• Welding and Cutting Equipment <br /> <br />• Water Truck <br />• Dozer <br />• Roller <br />• Concrete mixers/pumps/vibrators <br />Staging and Access <br />Temporary designated staging would be established within the WPCP fence line, at the southeast corner of the <br />basin and surrounding the existing WPCP drying beds to accommodate materials delivery, storage, assembly, <br />pipe laydown, and electrical configuration. Primary ingress and egress for construction vehicles would be from <br />Davis Street through the WPCP. <br />Project-Wide Rules <br />The Proposed Project would include the following best management practices (BMPs) to avoid or minimize <br />environmental impacts, which would be defined in the construction contract documents: <br />• Temporary erosion control measures would be implemented as specified in the Project-specific Storm <br />Water Pollution Prevention Plan (SWPPP), as applicable. The contractor will be required to comply with <br />NPDES/No. 2022-0057-DWQ NPDES No. CAS000002 (General Construction Permit). <br />• Equipment staging, material storage, and stockpile areas would be in upland areas so as not to affect <br />jurisdictional wetlands, or any other sensitive habitat.
