Bexar County Safety & Flood Control

Nothing is more important than the safety and well-being of the citizens of Bexar County. Over the past ten years, we have increased the number of Budget Law Enforcement Personnel by 40% and have more than doubled the Law Enforcement Budget.

Additionally, Bexar County implemented the High Water Alert Lifesaving Technology (HALT) Program by installing 52 new low-water crossing alert systems throughout the county to prevent drowning of motorists during local floods.


Bexar County, the City of San Antonio and the San Antonio River Authority formed the Bexar Regional Watershed Management (BRWM) partnership 10 years ago in an effort to provide more flood control, stormwater management and surface water quality throughout Bexar County. Twenty suburban cities in Bexar County also joined BRWM. The County contributes to this partnership through its $500 million regional flood control program. The program has completed 18 projects and has 52 more in various stages of design or construction. Additionally, Bexar County has implemented the High Water Alert Lifesaving Technology (HALT) Program for installations of a high-water detection system at various locations throughout the County. Phase I & II completed 52 locations to alert drivers to dangerous high water with either flashing lights or a combination of flashing lights and gates. Phase III will add  220 locations to the system.

Precinct 1

  • Bexar County has invested over $138million in Precinct 1 Flood Control projects.
  • Completed Shane Road – Project improved the low-water crossing and creates un-flooded access to Shane Road to remediate flooding. The project also included the installation of a bridge reconstruction and utility relocation. The project budget was $2.2 million, and we expensed $2.1 million.
  • Benton City Road Low Water Crossing – Replacement of a 3-barrel corrugated metal pipe drainage structure. Current configuration is both in poor repair and unable to safely pass stormwater runoff from significant rainfall events. The drainage structure is located within the existing 100-year floodplain. The structure replacement will provide for improved conveyance of storm water runoff while safely passing the 100-year runoff. Total estimated cost is $775,000.
  • VFW Boulevard – This project provides for the construction of a new storm drain system to reduce flooding near the intersection of Roosevelt Avenue and VFW Blvd. The storm drain will accept the water at the intersection and drain into the San Antonio River. The project will redirect runoff and prevent Mission County Park from flooding. The total estimated cost of this project is $9,981,045.

Precinct 2

  • Bexar County has invested over $103 million in Precinct 2 Flood Control Projects.
  • Completed Ingram Road – This completed project built a bridge along Ingram Road across Leon Creek and Huebner Creek between Northwestern and Potranco providing unflooded access during a 100-year flood event
  • Laddie Place Phase III – This project is located between Fredericksburg Road and Gardina St. The purpose of this project is to remediate flooding at and downstream of the Northwest Center by constructing a regional storm water detention pond. It will remove over 30 structures from the 100-year floodplain. The total estimated cost of this project is $30,391,524.
  • Woodlawn at 36th Street Drainage – This project consists of the construction of two barrels of culverts at Woodlawn and 36th Street. These two culverts will take the flood waters that currently flood the adjacent subdivision west of the two streets into the existing St. Mary’s University drainage channel. There are currently 134 homes in the floodplain adjacent to this project. The total estimated cost of this project is $13,975,000.

Precinct 3

  • Bexar County has invested over $83.1 million in Precinct 3 Flood Control Projects.
  • Olmos Dam – This completed project repaired Olmos Dam, which is important for the protection of downtown San Antonio. The total cost for this project was $5.9million.
  • Prue Road Low Water Crossing at French Creek – This project provides for the construction of a bridge at French Creek over Prue Road. The existing multi-barrel box culvert is undersized and must be replaced with a bridge. This also includes improvements east and west of the bridge. The total estimated cost of this project is $6,780,900.
  • Evans Road – Substantially completed, this project is located at Evans Road and Elm Creek. Construction includes a span bridge structure, roadway widening with taper-downs, channel grading, drainage easement acquisition, and utility relocation. The total estimated cost is $4 million.

Precinct 4

  • Bexar County has invested over $83.1 million in Precinct 4 Flood Control Projects.
  • Schaefer Road Drainage Phase I – Currently under reconstruction, the purpose of this project is to improve the existing water conveyance of a roadway section of Schaefer Road located in northeast Bexar County. This section of roadway is located approximately 0.5 mile east of the intersection of Schaefer Road and FM 1518. Schaefer Road crosses a low lying area that drains upland across the road and currently sheet flows across existing property to the south, ultimately entering Cibolo Creek. This project also includes land acquisition. The total estimated cost of this project is $8,824,733.
  • New Braunfels Low Water Crossing – This project increases the channel size and capacity at the upstream of Hot Wells Road and downstream of S. New Braunfels to contain the 100-yr water surface. Additional structures will require reconstruction of S. New Braunfels and Hot Wells Road. Right of Way acquisition and utility relocations are associated with the roadway reconstruction. The total estimated cost of this project is $10,640,236.
  • Calaveras Dam – This project raised the top of the dam, constructed an additional principle spillway, and modified existing auxiliary spillways. The total estimated cost for the dam improvements is $3.1 million. The United States Department of Agricultural-Natural Resources Conservation Service has funded $2.3 million, and Bexar County has contributed $1 million towards improvements.
