with lane closure and detouring elements. Comments from the meeting will be addressed and incorporated as applicable. A second constructability review meeting will be held, if needed, to obtain approval on this key element. Task 4.4-Storm Water Data Report A Storm Water Data Report (SWDR) is required on all Caltrans projects and focuses on the storm water quality issues to construct the project and implementation of appropriate temporary and permanent Best Management Practices (BMPs). CONSULTANT will prepare a PA/ED level SWDR summarizing project impacts to water quality, general mitigation measures, and recommend best management practices. The study will address only the impacts from roadway improvements and CONSULTANT will utilize Caltrans standard checklists. CONSULTANT will address the needs for erosion control measures and recommend BMP's for the project. Within the current project limits, the current R/W may not be sufficient to provide room for potential permanent treatment BMPs. CONSULTANT will consider various types of BMP measures utilizing Caltrans' Storm Water Manuals and Checklists. CONSULTANT will recommend appropriate BMP measures, such as grassy swales, detention basins, or infiltration basins, to minimize or mitigate the water quality impacts. CONSULTANT will assess the R/W needs to address the required BMP applications. Task 4.5—Drainage Impact Study Report and HydroModification Memo CONSULTANT will coordinate with Caltrans, C�TY staff, and adjacent projects; review as-built plans, previous studies, and proposed improvements to determine existing drainage patterns; and assess potential impacts to, or deficiencies of, existing storm drain systems in the project area. CONSULTANT will assess needed drainage improvements to serve the new facility including requirements for future development along the corridor. CONSULTANT will assess opportunities for storm water management and water quality solutions to minimize environmental impacts by the project. CONSULTANT will perform necessary hydrologic and hydraulic analyses, conceptual drainage design and cost estimate for proposed drainage improvements. CONSULTANT will summarize the findings in a Drainage Impact Study Report. Due to tidal action at the site, it is assumed that a HydroModification Report will not be required. A HydroModification Memo will be prepared to document this. Task 4.6-Location Hydraulic Study Federal Emergency Management Agency (FEMA)-designated 100-year flood zones cover large areas to the east of US 101 in the vicinity of Seaport Boulevard, Woodside Road, and Maple Street. Federal review of transportation projects within the 100-year floodplain is subject to Executive Order 11990, which requires consideration of alternatives and assessment of the project's impacts to the beneficial values of the floodplain. CONSULTANT will prepare a Location Hydraulic Study Report in accordance with Caltrans guidelines and requirements. CONSULTANT will identify the significance of the project impacts to the floodplains and make general recommendations on the possible mitigation measures.
