The scope of work is to complete a detailed structure file within the 500 year floodplain along the mainstem of the Lower Guadalupe River from the confluence with Bear Creek south to just downstream of Sequin. This is limit matches the downstream extent of the current H&H model. Work already competed includes creating a point shape file of structure locations in the study area and assigning ground elevations to those structure points. Remaining work includes assigning more accurate stationing to structures (with support from H&H), conducing a windshield survey to collect detailed information on structures including finished floor elevations, construction characteristics to determine depreciated replacement value, and occupancy types (single family, number of stories, multi -family, and commercial/industrial use). Following collection of field data, information will need to be reviewed and cleaned up, depreciated replacement values estimated, and data recorded into the structure file. Complete the socia -economic analysis writeup for the study area. Alternatives Analvsis Coordinate with H&H for developing with project HEC -FDA models for the New Bruenfels/Sequin, Wimberley and San Marcos damage centers. Once models are developed, HEC -FDA runs would be made and results summarized and compared to without project results to estimated benefits. Additionally, HEC -FDA runs will be made to identify any potential non-structural opportunities, especially in areas with residual damages. Coordination with real estate and cost estimating to develop alternative first costs and OMRR&R costs in order to estimate annual costs for comparisons to annual benefits for identification of the NED plan. Following TSP meeting, work with relevant PDT members for any refinements to modeling or costs and prepare revised economic analysis as necessary. Environmental and Cultural: This task involves assessing and documenting the existing project conditions, the Future Without Project Condition and the environmental impacts of identified alternatives in an Environmental Impact Statement (EIS) or other NEPA document. The Environmental Studies team would conduct necessary site visits to gather existing conditions and evaluate potential alternatives. The team would also conduct field work necessary to inventory, describe, and evaluate environmental elements identified as significant or important and warranting protection. The documentation will be coordinated with state and Federal environmental agencies and the public. All tasks would be completed by the Regional Planning and Environmental Center (RPEC) in the Fort Worth District, or its contractor. Public Involvement A minimum of two scoping meetings (one will be held to identify the publics' issues and concerns relating to the project. Resource agencies will be invited to join as a cooperating agency, during which time several meetings will be held to identify existing resources, impacts of alternatives, and attempt to resolve issues. A formal record will be made of discussions with the public and resource agencies. Letters, meeting records, or other forms of documentation will be prepared that document the correspondence and dialogue between agencies regarding the proposed project. Draft PMP — XX October 2016 13
