31 TAC § 361.39. Recommended Flood Management Evaluations, Flood Mitigation Projects, and Flood Management Strategies

(a) RFPGs shall recommend FMPs and FMSs to reduce the potential impacts of flood based on the evaluations under §361.38 of this title (related to Identification and Assessment of Potential Flood Management Evaluations and Potentially Feasible Flood Management Strategies and Projects) and RFPG goals and that must, at a minimum, mitigate for flood events associated with a 1% annual chance (100-yr flood), where feasible. In instances where mitigating for 100-year events are not feasible, FMPs and FMSs to mitigate more frequent events may be recommended based on guidance to be provided by the EA. Recommendations shall be based upon the identification, analysis, and comparison of alternatives that the RFPG determines will provide measurable reductions in flood impacts in support of the RFPG's specific flood mitigation and/or floodplain management goals.

(b) RFPGs shall provide additional information in conformance with guidance provided by the EA which may be used to rank recommended FMEs, FMPs, and FMSs with non-recurring, non-capital costs in the state flood plan.

(c) RFPGs shall provide the benefit-cost ratio for recommended FMPs in accordance with guidance provided by the EA.

(d) RFPGs shall recommend FMEs that the RFPG determines are most likely to result in identification of potentially feasible FMPs and FMSs that would, at a minimum, identify and investigate one solution to mitigate for flood events associated with a 1% annual chance flood event and that support specific RFPG flood mitigation and/or floodplain management goals.

(e) Recommended FMSs or FMPs may not negatively affect a neighboring area or an entity's water supply.

(f) Recommended FMSs or FMPs that will contribute to water supply may not result in an overallocation of a water source based on the water availability allocations in the most recently adopted State Water Plan.

(g) Specific types of FMEs, FMPs, or FMSs that should be included and that should not be included in RFPs must be in accordance with guidance provided by the EA.
