Agenda Item
Resolution - Engineering:
Consider a resolution authorizing the Mayor to execute Amendment No. 1 to Contract 16224, and related documents, with the Texas Water Development Board (TWBD), for a grant utilizing TWBD Category 1 Flood Infrastructure Funds (FIF) associated with the Flood Protection Planning of Watersheds Project.
Item Summary
The City of Lubbock proposes completion of flood protection planning activities for restoration of the Canyon Lakes System on the City of Shallowater-Yellow House Draw HUC-10 (1205000113), and the Buffalo Springs Lake-North Fork Double Mountain Fork Brazos River HUC-10 (1205000301).
The watershed study will include the development of comprehensive hydrologic and hydraulic models that will serve as planning tools to define and map flood hazard risks within the designated areas. The models will also provide a platform for developing and evaluating improvement alternatives. The updated models will be compared to the existing Federal Emergency Management Agency (FEMA) floodplain maps and all differences will be noted. Coordination with FEMA will occur throughout the process so that the submitted data complies with the latest FEMA requirements.
The proposed flood protection planning study will include the development of new hydrologic and hydraulic models or update existing models for the study area. The models will utilize the latest estimates of rainfall for the area (Atlas 14), which will develop inundation maps representing existing conditions for the 2-yr, 5-yr, 10-yr, 25-yr, 50-yr, 100-yr, and 500-yr storm events. It will also identify areas at risk for structural and major roadway flooding due to riverine conditions. This study will also assist with community outreach and education of the public about study purpose, findings, and project recommendations.
Amendment No. 1 revises the original grant agreement to include new regulations implemented by the Texas Water Development Board when using grant funds. This amendment will extend the grant to September 16, 2024. No additional funding is required by the City of Lubbock with this proposed amendment.
Fiscal Impact
This amendment does not include any additional funding requirements by the City of Lubbock.
