Land Values 1997 - 2007

Information compiled by the "Land Trends" project and based on tax information collected by the state comptrollers office regarding the value of land per acre in each school district. The three maps include: 1) value per acre in 1997, 2) value per acre in 2007, and 3) percentage change in value from 1997 to 2007. The maps show substantial gains in land values with the higher values reaching further into the interior of the Hill Country. Many land valued doubled and tripled in value and some areas even quadrupled in value.


Regional Growth 2010 - 2100

Data taken from Texas State Assessment of Forest Resources Draft 26 Sept 2008. Data layer uses available data to project likely development patterns into the future. Data used for the evaluation included projected population growth and current land use patterns. The study covered the entire Southearstern United States and looked at per decade growth from 2010 to 2100.
