Edwards Aquifer Protection Program

The Edwards Aquifer Protection Program (EAPP)

Green Spaces Allianceworks with willing landowners who voluntarily elect to conserve their land in Bexar, Medina and Uvalde counties. As the goal of the EAPP is to ensure water quality and quantity, a team of experts use scientific criteria including ecological, biological, and hydrological to evaluate the potential of the land under consideration to contribute toward aquifer recharge. Next, an appraisal is conducted to determine the value of the property with its development rights removed. Upon approval by the Conservation Advisory Board and the City of San Antonio, a permanent conservation easement is placed on the property and the owner is compensated for the value of the of the development rights that have been voluntarily relinquished.

What is a Land Trust?

A land trust is a nonprofit organization that works to protect natural areas by negotiating voluntary agreements with private property owners to leave their land undeveloped in perpetuity.

What is a Conservation Easement?

McGown RanchUnder a conservation easement, land remains in private ownership; the land-owner chooses to maintain the property in its current natural condition and not to develop it, thus protecting important conservation values such as wildlife habitat, quality and quantity of drinking water, open space, scenic vistas, air quality, biodiversity, native vegetation, capacity for aquifer recharge, and family heritage. The landowner retains his or her current use of the property and agrees to allow periodic monitoring to ensure that the conservation values described in the easement are upheld. Some conservation easements may provide tax advantages to the landowner.
