Edwards Aquifer Protection Program

In November 2010, voters approved the continuation of the 2005 sales tax (up to $90 million) for the Edwards Aquifer Protection Program. This initiative, also called Proposition One, authorizes the City of San Antonio to continue the watershed protection and preservation projects initiated in 2000 and continued in 2005. The City continues to protect the Edwards Aquifer by acquiring and preserving land across strategic areas of the aquifer's recharge and contributing zones. By working with scientists, conservationists, landowners, and concerned citizens, the City of San Antonio looks forward to building on the success of the past aquifer protection initiatives.

Two land trusts (Green Spaces Alliance and Texas Nature Conservancy) work with the City to identify parcels of land that would be appropriate for the Edwards Aquifer Protection Program — most of these parcels are brought into the program by CEs, rather than as fee purchases.

The trusts work with the landowners and manage much of the due diligence leading up to the closing of the CE. The trusts executes an option agreement with the landowner and, just before closing, the CE is assigned to the City.
