and from the evaluation of the new model result data within each participating community. The alternatives will include both structural and non - structural improvements. The flood damage reduction alternatives will include economic analysis and justify alternatives, if any, for specific storm frequencies within each participating community. The effects of each alternative scenario and resulting level of flood protection with respect each alternative will be analyzed and incorporated into the overall effect on the watershed by the USACE, GBRA, and their contractors, relative to its derived benefit to the participating. A detailed report that summarizes the findings of the study and modeling results will be prepared and presented to the Project Management Committee. Reports will include presentation of the methods of analysis, summary of results, exhibits, model output, and benefit to each member of the Committee. 8) Benefit /Cost Analysis — The benefit of each alternative in terms of level of protection /reduction of flood damages, impacts, right -of -way requirements, environmental impacts, etc. will be made in comparison to the associated cost of each improvement. From this benefit /cost analysis, a set of solutions will be presented in a report, which will document the benefit criteria, cost information and other considerations. The purpose of this report will be to communicate the results of the Project to a broad audience that may include technical and non - technical people. The results of the Benefit -Cost Analysis will be presented at a public meeting. The USACE, GBRA, and their contractors will provide preliminary cost estimates for each alternative developed to reduce flood damages within each participating community. The economic analysis necessary for the analysis of alternatives in each community, or alternatives benefiting multiple participating parties as agreed will be presented in a public meeting. The contractors will prepare any exhibits necessary for the report and public meeting for alternatives. 9) Implementation and Phasing — Following the public input pertaining to Benefit/Cost for the flood protection scenarios, the project will also include initial recommendations for the implementation and phasing of the identified improvements, both structural and non - structural. An implementation plan will identify potential funding sources for the improvements, such as drainage utility fees, impact fees, public /private partnerships, special utility districts, etc., as appropriate. Consideration of current Capital Improvements Plans will be important to ensure that the recommended flood protection strategies are coordinated and consistent with planned projects. 10) Final Deliverables — At the conclusion of the study, the USACE, GBRA, and its contractors will prepare a final report be presented to the TWDB and will likely include maps, technical analysis, supporting documentation, and the implementation and phasing plan.
