The date(s) and description(s) of the most recent flood protection planning the proposed planning area. The following are the most recent flood protection planning efforts undertaken in the City of San Marcos: Camp, Dresser & McKee. Drainage Master Plan: City of San Marcos. August 11, 1994.

Federal Emergency Management Agency. Flood Insurance Study. Hays County Texas and Incorporated Areas. DRAFf, October 2004. This is the draft DFIRM product and study prepared under Map Modernization. This study does not reflect the most current conditions, despite its current date. 27. A description of how the proposed planning will coordinate with other flood protection plans or facilities in the planning area, surrounding regions, and the State. Other entities which have an interest in flood protection in the planning area have been invited to participate in the effort. The City is fortunate to have the participation and support of Hays County, the GBRA, and the BAA in the study. In order to avoid duplication of efforts and resources, the City will continue its coordination with FEMA, the Anny Corps of Engineers, NRCS, TCEQ, TxDoT and the Union Pacific Railroad at the onset of the project, to identify any additional ongoing or proposed projects. As the scope of work proposed will involve an analysis of potential upstream and downstream impacts, any overlapping scopes of work will be coordinated with the respective Federal, State, Local or non-governmental entity, to avoid duplication and cross-purpose undertakings. The adopted Region "L" Water Plan provides the guidance for coordinated water supply strategies in the south central Texas planning region, which includes the City of San Marcos, Hays County, GBRA and BAA. Table ES-3 lists the recommended strategies for these entities in seeming future water supplies. One of the strategies listed for the City of San Marcos is additional storage, which could take the form of a dual-purpose flood protection and water supply reservoir, or an aquifer storage and recovery (ASR), project. Recharge enhancement projects have also been evaluated by the BAA. Diversifying and increasing the supply of water for the City of San Marcos has potential benefits for both the City and the Edwards Aquifer Authority.
