Central Texas Greenprint for Growth

Central Texas Greenprint for Growth

"The Central Texas Greenprint for Growth is a tool for balancing sustainable conservation goals with the infrastructure needs of our rapidly urbanizing region. The process combines community stakeholder input about conservation goals and priorities with Geographic Information Systems mapping and modeling technology to produce graphic illustrations highlighting opportunity areas for conservation that meet multiple goals. For the complete Central Texas Greenprint for Growth Report please visit our Publications page."

Texas Ecological Assessment Protocol (TEAP) Report

Texas Ecological Assessment Protocol (TEAP) Report (EPA 906-C-05-001)


findings:  some of the areas that have high or moderately high ecologically important areas are the Edwards Plateau

The Texas Ecological Assessment Protocol (TEAP) relies on a previously developed methodology and consists of collecting and analyzing existing electronic data available statewide, which was used to evaluate the following three ecological criteria:
1. Diversity
2. Rarity
3. Sustainability
What areas have the most diverse land cover? What areas have the highest number of rare species and land cover types? What areas can sustain ecosystems now and in the future?

2.2.1 GIS Level Screening
2.2.1.1 Compilation of GIS Information
At this stage, the evaluation involves gathering the relevant watershed data using
local knowledge as well as relevant GIS themes to assist with site-specific evaluation. Collect and compile any of the following information, as available:

• Soils type data (or alternatively, zones of poor infiltration)
• Topographic contours and/or slope map data (used to identify areas of
  prohibitively steep slopes)
• Digital elevation models or other topographic data (used to verify/identify
  drainage areas)
• Groundwater elevations/depths (used to identify areas of high groundwater elevation)
• Floodplain (e.g., FEMA) map data (used to identify areas where flood control isrequired)
• Landslide and/or liquefaction zones (used to identify areas at risk for landslides or liquefaction)
• Biologically or Environmentally Sensitive Areas (BSA/ESA) and/or wetlands mapping data (used to identify significant habitat/wetland areas)
• Aerial photographs at the highest resolution available (used to visually assess parcel/catchment and adjacent land characteristics)
• Impervious surfaces (used to identify impervious and pervious areas for BMP implementation)
• Parcel ownership (used to identify whether parcels are publicly or privately owned)
• Storm drain as-built drawings (including flow direction, slopes, invert elevations, pipe sizes)
