Attachment A <br />Scope of Services <br />Key Project Deliverables <br />- 20 -year Capital Improvement Project Program for years 2020, 2025 and 2035 <br />• Flood protection projects for creek and localized (storm drain) problem areas <br />• Creek/river stabilization projects, coordinate opportunities with the HCP/WQPP <br />• Prioritizes projects based on severity of problem, emphasis on public safety <br />• Includes water quality opportunities when possible /available <br />• Operations and maintenance guidance <br />- Identification of potential project partners and funding sources <br />- Floodplain mapping consistent with the ongoing GBRA /USACE Interim Feasibility Study <br />for FEMA, adoption in 2015 (Cottonwood and Sessom Creeks outside of GBRA/USACE <br />scope) <br />- Summary of regulatory options for flood, erosion, and water quality protection <br />- Summary and recommended coordination of ongoing water resource efforts and <br />opportunities <br />Study Area <br />- Planning for the watersheds of the San Marcos and Blanco Rivers and Cottonwood, <br />Purgatory, Sessom, Sink, and Willow Springs Creeks and their tributaries <br />- Includes floodplain mapping and solutions project directed by GBRA (Guadalupe - <br />Blanco River Interim Feasibility Study) and San Marcos airport in the study area <br />- Will develop CIP project list to the City limit boundary <br />Task Summary <br />1. Data collection <br />a. Storm drains, land use plans, complaints, GBRA flood study data <br />2. Field reconnaissance, surveying, and mapping <br />3. Hydrologic study (watershed scale) <br />a. Incorporate GBRA flood study work <br />b. Develop model for Cottonwood Creek <br />c. Investigate regional detention opportunities <br />4. Hydraulic modeling (watershed scale) <br />a. Incorporate GBRA flood study work <br />b. Delineate floodplains, identify flood -prone areas <br />c. Evaluate and develop floodplain management solutions <br />5. Storm drain system analysis <br />a. Analyze drainage complaint areas and develop solutions <br />6. Creek erosion assessment <br />a. Identify erosion hazard areas and potential future cost implications if un- <br />managed <br />b. Prepare conceptual solutions and opportunities with HCP/WQPP /Corps projects <br />7. Capital Improvement Plan <br />a. Develop prioritization system to rank and compare projects <br />b. Identify multi- objective opportunities <br />c. Prepare recommended capital improvement plan <br />
