Flood Protection Plan: Phase 2

Flood Protection Plan: Phase 2

Date: August 2011
Creator: Ambiotec Civil Engineering Group
Description: "The purpose of this study was to expand on the Phase I City of Brownsville Flood Study that was developed in 2006 to expand the study area to include two additional Brownsville watersheds in the Northwest quadrant of the City and to create a linked watershed model to allow for the investigation of inter watershed transfers of storm-water flow between the watershed studied in 2006. This study analyzes several of the gaps identified in the 2006 Flood Study by 1) developing baseline models to assess existing flooding risks in the Resaca del Rancho Viejo (RRV) and Cameron County Drainage District No.1 Ditch No.3 (CCDD#) watersheds; 2) examining the impact of storm surge on each watershed; and 30 linking the hydraulic models for those watershed that are hydraulically linked. This study, like the 2006 study, is meant for planning use only and should not be used for engineering design purposes" (p. ii).
