Flood Protection Master Plan
Background Information:
This project will use CDBG-DR funds to develop a flood emergency warning system (FEWS). The FEWS will be used as a tool for emergency management, City staff, and the public prior to and during flooding events for both riverine and local flooding conditions. Ultimately, the FEWS will help identify the impacts of potential flooding based on the amount of rainfall or flow in streams within the City and/or from upstream watersheds.
This project will be conducted in two phases. Phase 1 will consist of conducting a feasibility study and Phase 2 will consist of implementing the FEWS. The development of the FEWS will consider the following:
• To assist emergency management identify areas for evacuation, establishing routes for responders, potential road closures and selection of evacuation centers.
• To provide the public information regarding the potential of flooding conditions
• Utilization of existing rain and stream gauges operated by others
• Identification of new rain and or stream gauges including location, operation procedures, etc.
• A system that can be utilized and accessible any time or day (24 hours).
• An evaluation of areas of previous reported flooding including the date, location and an estimate of rain or flow amounts reported or recorded.
• Along riverine systems (major street crossings) and specific locations within the City (subdivisions, etc.) develop a comparison of peak flows, depth of flooding and associated rainfall amount.
This Resolution in the amount of $57,580 will cover Phase 1 engineering services to develop a flood emergency waning system. Phase 1 Scope of Services includes:
• Project coordination including a kick-off and status meetings.
• Conduct regional planning meetings with various regional FEWS owners including the National Weather Service, US Geological Survey, Texas Water Development Board, Texas Department of Transportation, Hays County, and other similar size cities.
• Conduct an inventory of existing precipitation and stream gauges within the San Marcos areas and Blanco River watershed.
• Evaluate and develop recommendations regarding weaknesses and gaps within the existing gauge network including network enhancements
• Summarize findings in a report including recommendations for Phase 2 services.
