WHAT WE DO
Bexar County’s Storm Water Pollution Prevention Program was created in 2008 and established the guidelines for the Bexar County Stormwater Quality Program, as well as the Post Construction permit. The purpose of this program is to address the sources of storm water discharges which adversely affect the quality of our County’s waters. The program utilizes permitting and inspections of construction sites, post construction maintenance, public education and outreach, and illegal discharge detection to keep our rivers, lakes, and streams healthy.
There are five (5) areas the program focuses on:
- Post Construction Site Evaluations and Inspections
- Public Complaints
- Illicit Discharges
- Unknown and/or Hazardous Spills
- Post Construction Maintenance
Funding & Costs
In order to fund the Post Construction program, the County collects a Federal Storm Water Quality Fee. This fee is dedicated for the sole purpose of preventing pollution and improving our storm water quality. The fee will be identified on the property tax bill and only applies to property owners with improved land located in the unincorporated area of Bexar County. The rate will vary by lot size and property use, but the average homeowner will only pay $10‐$14 annually.

Storm Water Quality has two different permits:
- Storm Water Quality Site Development Permit (for use during construction only)
- Post Construction Storm Water Control Measure Permit (remains with the property for life)
Sites Over The Edwards Aquifer
If a Water Pollution Abatement Plan (WPAP) or Contributing Zone Plan (CZP) is required for the site, a permit is required, but no additional mitigation is required. The storm water control measures to be implemented for the WPAP/CZP will be the measures permitted. All permitting submittal requirements will stay the same (see below). Since the BMPs to be permitted have already been reviewed by TCEQ for the WPAP/CZP only the $50 application fee will be assessed. The $200 review fee will not be assessed.
Post Construction Storm Water Control Measure Permit
A Bexar County Post Construction Permit is required whenever one (1) acre or more will be disturbed in the unincorporated area of Bexar County for construction or reconstruction. Post Construction permits are also required if the disturbed area is under one (1) acre, but part of a Larger Common Plan of Development (such as a housing subdivision or business park).

The review process for the Pre-Construction section will be triggered when all of the above submittals are received by our office. The review time is 30 days.
The Post Construction requires an annual renewal beginning one (1) year after the completion of the site at a cost of $50. The owner of the site will be required to conduct routine maintenance inspections during the year to ensure that any mitigation on site is working in accordance to the permit submitted.
Post Construction Permit Inspection Process
The owner of the permit is expected to conduct annual or quarterly inspections of any permitted mitigation on site. Based on complaints and a lack of maintenance reporting by the owner, inspections of the mitigation will be made to assess compliance. If an owner is found to be in noncompliance, a violation letter will be sent to notify the owner of the noncompliance. If the owner continues to stay in noncompliance, other enforcement can be taken such as the issuing of a citation or fine.
Post Construction Review
The review process for the Post-Construction section will be triggered when the above submittals are received by our office. Once received, an inspector will go out to the site to visually confirm the locations of the BMPs and collect photographs of the BMPs for our records.
After final approval of the permit, the owner is expected to begin routine maintenance and inspection of the BMPs permitted. Quarterly maintenance reports are to be emailed to Bexar County Post Construction. If maintenance lapses for over a year or if quarterly reports are not received, a violation letter will be sent and a renewal permit with an engineer certification will be required to bring the site back into compliance.
Maintenance Provider Certification
Those who will be providing maintenance for the permitted BMPs will be required to have a certification. The current certification that is approved by Bexar County is being provided by the San Antonio River Authority (SARA).
Bexar County Storm Water Quality Program follows the rules laid out in the Commissioners’ approved Court Order. The court specifically refers to the TCEQ Edwards Aquifer Manual, General Construction Permit, and Phase II MS4 Permit. Below is a list of the various regulations that are enforced by the Storm water Quality Program.
- Bexar County Stormwater Court Order
- Edwards Aquifer Manual RG‐348
A violation occurs when a pollutant is introduced into the municipal separate storm sewer system (MS4) or into a body of water. The MS4 is anything that can convey water. This includes, but is not limited to:
- Drainage channels
- Storm sewers
Examples of violations are:
- Vehicles leaking oil or other fluids into the street
- Filling in floodplain
- Illegally dumping near or in the MS4 or waterway
Notice of Violation Process
- One of the first things that should be done when a notice of violation is received, especially if the violation (or how to remediate it) is not understood by the property owner, is to contact our office. A Post Construction inspector will be able to answer your questions and guide you back into compliance. The goal is always to assist with compliance. The constituent should be sure to have a copy of their Notice of Violation with them. This will have important information on it that will help the inspector identify the work order and be better able to assist them.
- A follow up inspection is set for the specified time after the notice of violation is received. This time is determined by law, the seriousness of the violation, and the expected/reasonable time it will take to correct the problem. If the certified letter is returned unclaimed, the inspector will post the Notice of Violation Letter onsite, and that will be considered legally received by the owner.
- If after the follow up inspection, the violation has come into compliance, no further action is taken – the notice of violation will be closed.
- If after the follow up inspection, the violation has NOT come into compliance, additional legal action may be taken, but all efforts will be made to work with the owner to come into compliance.
