Environmental Information
As the largest base organization in the DoD, Joint Base San Antonio comprises multiple military locations including Lackland, Fort Sam Houston and Randolph. As stewards of our environment, we are committed to keeping our community informed of local environmental policies and issues, and of our efforts toward making a greener military.

Operation/Training Noise Concerns

Flying Operations

As the largest DoD base organization, JBSA operates multiple busy airfields across San Antonio. We understand our flying operations sometimes affect our neighbors, and we work hard to minimize any adverse impact without compromising safety. Flight patterns are designed to reduce over-flights of populated areas and therefore reduce the noise disturbance to residents.

JBSA is home to multiple flying units including the 433rd Airlift Wing, also known the Alamo Wing, the 149th Fighter Wing and the 12th Flying Training Wing. These units provide both real-world and training operations that are integral to the support of worldwide defense operations.

For safety reasons, pilots are required to fly within pre-set corridors established by the Federal Aviation Administration. Although flying missions are conducted within these corridors, most flying operations are done over sparsely populated areas. Flying altitudes and flight patterns designed to minimize the effect of noise on surrounding communities.

Military aircraft have high-thrust engines, and several flight paths cross over the local area around San Antonio, which means some area residents will hear noise generated from flying activities. Atmospheric conditions such as temperature, winds and humidity also have a significant impact on the level of noise generated by aircraft operations. Cloudy weather can increase noise levels as sounds reverberate off the clouds, emitting louder than normal levels. Certain weather conditions also require pilots to adjust take-off directions and flight paths. Seasonal changes like daylight savings time also affect departure and arrival times.

While JBSA leaders cannot participate in the local civic decision-making process, we work to identify development proposals that may not be compatible with our military training missions. Base leaders are committed to providing information about our operations to government leaders, community planners, developers and concerned citizens so they can make informed development decisions.

We are aware of the environmental impact our operations may cause and strive to minimize public inconvenience. We do not like to disturb those whom we are sworn to defend, so we continually balance the necessity for realistic training against the desire to be a good neighbor.

Small Arms/Explosive Ordnance Training

Residents near JBSA training areas may periodically hear noise from the small arms training ranges or blasts from explosive ordnance training. If you hear blasts and are unsure whether or not it is associated with training at JBSA, please contact your location's appropriate public affairs office.

JBSA Water Restrictions

Joint Base San Antonio Stage I Water Restrictions in Effect.

Current as of 1 August 2017

The JBSA Base Civil Engineer declared Stage 1 Water Restrictions are in effect.

The biological opinion limits JBSA's water draw from the Edwards Aquifer in order to protect eight endangered species which live in the aquifer and its associated springs. These species can only survive when aquifer levels and spring flows are adequately maintained.

All the normal (non-drought) restrictions are still in place; in addition to Stage 1 water restrictions, such as:

  1. Landscape watering with an irrigation system, sprinkler or soaker hose is allowed only once a week before 1000 or after 2000 on your designated watering day, as determined by your address or facility number as shown in Table 2, JBSA Critical Period Management Plan (http://www.jbsa.mil/Portals/102/Documents/Energy%20Awareness/AFD-130809-013.pdf)  

  2. Reduce water consumption by any means available

  3. New turf/landscaping may be watered until adequate growth is maintained

  4. POV washing is allowed once per week on Saturday or Sunday, using a positive shutoff nozzle to prevent water waste. Water should not be allowed to run into the street

  5. All swimming pools must have a minimum of 25% of the surface area covered with evaporation screens when not in use (inflatable pool toys or floating decorations may be used)

  6. Hand watering with a hand-held hose, soaker hose, drip irrigation, bucket or watering can is permitted any time and any day

  7. Washing impervious cover such as parking lots, driveways, streets or sidewalks is prohibited except in order to correct life, health, or safety concerns

  8. Irrigation of athletic fields is permitted only as required to maintain the turf viability/safety

  9. Landscape on golf courses are required to follow one-day-per-week watering

  10. Use of fountains, waterfalls, or other aesthetic water features outdoors or indoors is prohibited, unless a variance has been granted for 100% non-potable water use

All water restriction measures are listed in the JBSA Critical Period Management Plan available online at http://www.jbsa.mil/Portals/102/Documents/Energy%20Awareness/AFD-130809-013.pdf.

All utilities/well permit holders (including JBSA and SAWS) who withdraw water from the Edwards Aquifer are required to reduce withdrawals as the level of the Aquifer drops. Many water utilities, such as SAWS, have alternate sources of water that is not pumped from the Edwards Aquifer. Information on SAWS Aquifer Storage and Recovery can be viewed at http://saws.org/Your_Water/WaterResources/projects/asr.cfm.

For more information or for reporting of water abusers and will bring potential disciplinary measures to violators, call (210) 652-2392.

JBSA Info for Home Buyers

Consumer Confidence Report

The CCR, or Consumer Confidence Report, is an annual report that summarizes the quality of the drinking water provided to our customers. Each year, Bioenvironmental Engineering (BE) and Civil Engineering (CE) are required to conduct water sample analysis/tests as part of U.S. Environmental Protection Agency (EPA) requirements. These collected samples are analyzed by state certified labs and are validated by Texas Commission of Environmental Quality as well as BE and CE water program managers. These water sampling requirements and the respective analysis results are provided in the CCR.
