The San Antonio River Authority owns, maintains and/or operates assets in the San Antonio River Watershed which covers Bexar, Wilson, Karnes and Goliad counties including dams, parks, and wastewater treatment plants. The parks include the San Pedro Creek Culture Park as well as the Museum and Mission Reach segments of the River Walk. It also includes several nature based parks located throughout all four counties. If you are looking to develop in the Museum or Mission Reach segments or adjacent to the San Pedro Creek Culture Park, the City of San Antonio Unified Development Code requires a formal coordination with the San Antonio River Authority as part of plats and building permits. Please contact us at email@example.com or at 210-302-3666 for more information on the items below.
If you are considering development adjacent to the River Walk or San Pedro Creek, you will be required to coordinate with the San Antonio River Authority per the City of San Antonio’s Unified Development Code 35-673.
As part of the coordination, SARA requests that the developers provide information on their development in the preliminary phases. For most projects, SARA will want a full set of plans and specifications. Earlier coordination is better.
The contact information for development is: firstname.lastname@example.org or 210-302-3666.
Below is a list of typical items that SARA will want information on regarding your development. This is not an all-inclusive list.

If you are proposing to perform work on the Museum Reach, Mission Reach or San Pedro Creek that will impact the trail system, you will need to comply with the City of San Antonio’s Unified Development Code 35-673 (c) (8) a. iv which requires coordination with the San Antonio River Authority (SARA). SARA recognizes that these trail systems are heavily used and strives to minimize public inconvenience while working with developments adjacent to Museum Reach, Mission Reach and San Pedro Creek.
You will need to obtain a permit or license from SARA. Submission of a completed application and payment of associated costs does not guarantee that a permit or license will be issued. If work is completed earlier than anticipated a refund will be issued for the days that were not used for the trail closure. Please allow 10 business days for review of your application. Trail closures are granted on a first come, first serve basis and are limited to six months.
Send Permit Applications to: SARA Developer Resources, email@example.com, 210-302-3666
Permit for Intermittent Closure– Impacted with maintenance or equipment and will have flaggers at all times to temporarily (less than 2 minutes) hold traffic or guide traffic around the equipment.
Permit for Partial Trail Closure – Minimum width 5 feet must be open. Must only impact a 20 foot long area or less.
License for Full Trail Closure – A License Agreement will be required for a full trail closure. SARA will provide site specific license agreements once the work is defined.
- Intermittent Closure
- Signage may be required, at SARA’s discretion.
- Provide a narrative of the closure, how the construction will safely take place and how the public will be protected.
- Partial Trail Closure

- Map should include an ADA access alternate route
- Map should have both the alternate route written out and mapped out
- Map should clearly explain the Trail closure from access point A to access point B. It is recommended that the trail closure be highlighted in red as seen on the example
- Signage should clearly explain the alternate route be highlighted in yellow
- Map needs to have a name and contact phone of individual responsible for the project should the public have questions.
- Map must have SARA’s logo at the bottom

Payment is currently accepted by check. Please make your check payable to the San Antonio River Authority. Payments are accepted at the SARA Environmental Center, 600 E. Euclid, San Antonio, TX 78212. To confirm fees please e-mail firstname.lastname@example.org or call 210-302-3666.
The San Antonio River Authority, in conjunction with the City of San Antonio, sought inclusion of the new, voluntary LID/NCDP use pattern into the Unified Development Code (UDC)
- To eliminate the need for variances to utilize LID practices
- To add incentives to encourage use of LID practices, and
- To establish performance standards required to earn the incentives
The City of San Antonio also requested the River Authority to include amending the Conservation Subdivision use pattern in the project, again to provide greater incentives to make use of the code more attractive.
- Under the amendment to Section 35-210, developers using LID/NCDP practices can qualify for two types of incentives: credit/offset-based and fee-based.
- For new development, the first 1.5” of rainfall falling on the developed area during the 24-hour rain event shall be managed. For a redeveloped site, the first 1.18” of runoff in a 24-hour event shall be managed.
- If a minimum of 60% water quality volume (WQV) from increased impervious cover, then the applicant is eligible for the credit offset incentives in table 210-1 below.
- Applicants using LID/NCDP practices and managing less than 60% of the WQV shall be eligible for credit/offsets 1 through 4 in the table below.
- If less than 100 percent of the WQV is managed, first priority is to be given to managing runoff from parking and street areas within the development limits.
|1. Stream Buffer or Stream Restoration to Parkland Acre||1.5|
|2. Stream Restoration to Tree Canopy||1.25|
|3. Linear Park to Parkland Acre||1.5|
|4. LID BMP to Tree Canopy||1.5|
|5. LID BMP to Streetscape Tree||1|
|6. LID BMP Landscape Elective Credit||Up to 25 points|
|7. LID BMP Drainage Area to Parkland Acre||1.5|
|8. Density Bonus||10%|
- Applicant managing a minimum of 60% of the WQV shall receive credit and offset incentives for LID/NCDP according to Table 210-2.
- Stormwater Fee Discount: Specified in Section 34-7.07.
- Stormwater Fee in Lieu of Discount: See Table 210-2.
|Percent of WQV Managed (volume resulting from first 1.5” in 24 hours on developed site)|
|FILO Fee Discount|
|Meets LID Performance Standard||5%||10%||20%||25%||30%|
|Meets Detention Requirements or Increases Channel Storage through NCDP|
- Permeable pavement shall not be counted as impervious cover if designed to store the 2-year, 24-hour storm event.
The San Antonio River Authority maintains and operates 28 dams in Bexar County and 13 dams in Karnes County. The structures are vital flood retarding structures that are designed to detain storm water for current existing conditions. If you are looking to develop near these dams, please contact us to at email@example.com or 210-302-3666 to discuss your development’s impact on the dam.
