Flood hazard zones in the vicinity of Alamo Ranch

The map below shows the currently mapped flood hazard zones in the vicinity of the Alamo Ranch area of far northwest San Antonio.  The effective date for these maps is September 2010.  There has been significant construction of homes, commercial buildings, and drainage infrastructure since that time.

The definition of the "100-year" flooding event that is the basis for the construction of the 1.0% Annual Chance Flood Hazard Zone is very likely to change based on increased frequency of major rainfall events in recent years. However, no information was found regarding plans for updates to these maps.

These maps and others for any area of interest around San Antonio are available via the interactive map viewer at the address below:

Culebra Crossing

Maps of interest to Western Bexar County Alliance Group

Map 1:  City of San Antonio Proposed Annexation based on Lackland AFB perimeter


The large '2017' area was subsequently reduced to a perimeter based on a certain distance from Lackland Air Force Base.  The modified area was put to the vote in November 2018 and was overwhelmingly defeated.

Two Options were on the ballot:

Option 1: Approve annexation of the area by the City. This Option received 16.02% of the vote.

Option 2: No annexation, but the City reserves the right to impose land use regulations in the area to "protect the military missions".  This Option received 83.93% of the vote.


Map 2:  City of San Antonio Master Development Plan land use summary


This map has been compiled by the City from various sources.  Outside of the city limits it does not represent any official City zoning or future plan.  

Of particular interest to Alamo Ranch area residents is the plan for the corridor along Wiseman Boulevard between Loop 1604 and Talley Road.  The map shows the entire zone as "Commercial/Multifamily".  The inclusion of the 100% Residential Fronterra at Westpointe.and other nearby neighborhoods in this zone shows the map to be outdated.
