San Marcos Floodplain Management Plan: A Sustainable Future for Floodplain Management Application for Flood Protection Study Grant 34. A description of how Dood protection needs of the entire watershed will be considered. The watersheds selected for study are in varying levels of development. New development, predominantly in the upper reaches of the watersheds, is managed by the Citfs development ordinances and the floodplain management ordinance. Structural improvements in these new developments will be built with consideration of ultimate watershed conditions and include provision for any of the specific structural solutions identified in the scope of this planning project Coordination with Hays County during the development review process will be critical, particularly in areas within the ETJ, but this planning project will enable both the City and County to plan for and implement the identified solutions based on a common understanding of the entire flood protection needs of the watershed. Older development in the watersheds, which is most affected by the floodplain (pre-FIS), will likely be protected by detention upstream and possible channel improvements. However, the impact of all improvements will be considered with respect to maintaining or lowering BFEs throughout the watershed, such that flood protection is achieved to the maximum extent possible. The floodplain maps to be generated in this project will include the lOO-year and lOO- year ultimate floodplains with base flood elevations. This information will provide the basis for the improvements and possible FEMA floodplain map revision. The City will use this information for floodplain management as part of their admini~tration of the NFIP. The improvements identified and prioritized in the implementation and phasing plan include, by virtue of the process described in this scope, a comprehensive understanding of the environmental resources and constraints, benefits, and costs associated with meeting the flood protection needs of the City. 35. Method of monitoring study progress. The progress of the study will be monitored generally according to the proposed work schedule and interim deliverables and public meetings. A total of 15 progress meetings of the stakeholders/advisory committee will be held to discuss the study and any issues which may be causing delay. These meetings will essentially follow a monthly schedule, with some shifting to be expected. In addition, progress reports itemized by task will be prepared and submitted to the TWDB with each invoice for payment of project-related costs. Further, at each of these monthly meetings, a qualitative assessment of the six goals of the project will be made. This will serve to keep all parties close to the overall mission of the project - the development of a sustainable flood protection plan.. The six goals again, are: · Minimize the exposure of lives and property, · Serve multiple objectives (such as flood mitigation, erosion control, water quality control, and potentially water supply), M:lactivel04POI2 San Marcos M.D.P1Grant Applic..sMa.dc.f!xhililt A, Page 22 December 16, 2004
