Environmental Impact Assessment
Overview
The 3-acre site will be located over the Edwards Aquifer. In order to ensure the protection of this vital
natural resource and its inhabitants, PAGGES Engineering will be reviewing and assessing several
factors. This will include TCEQ Edwards Aquifer rules and regulations, 100 year floodplain, TCEQ
Storm Water Program, Endangered Species Act, City of San Antonio Tree Preservation Ordinance,
Clean Water Act, and the Antiquities Code of Texas.
Texas Commission on Environmental Quality (TCEQ) Edwards Aquifer
The counties of Williamson, Travis, Hays, Comal, Bexar, Medina, Uvalde, and Kinney are regulated by
TCEQ for land lying within the Edwards Aquifer. TCEQ has set forth rules to guarantee that polluted
runoff does not negatively impact the quality of water in the Edwards Aquifer. The three primary zones
in the Aquifer are the contributing zone, recharge zone, and the transition/artesian zone (as shown in the
“Edwards Aquifer Contributing Zones” map). According to TCEQ, the recharge zone is defined as the
region “where geologic layers of the aquifer are exposed at the surface and water infiltrates into the
aquifer through cracks, fissures, caves, and other openings throughout these layers.” Generally, any
contaminants present in the groundwater in this zone can easily get into aquifer, so a Water Pollution
Abatement Plan (WPAP) is required. The contributing zone (Texas Hill Country) consists of watersheds
that drain water from rainfall into rivers and streams that flow or infiltrates into the water table aquifer.
Additionally, the transition zone is a narrow strip of land whose geologic features (faults, fractures,
caves, and sinkholes) make it possible for contaminants in the surface water to flow into the aquifer.
This proposed project will be situated in the contributing zone within the transition zone that is one of
several small regions south and southeast of the recharge zone where water flows to streams that cover
the recharge zone (shown in “Edwards Aquifer Zone Map.”). Furthermore, the proposed site location
does not lie within the 100-year floodplain, so Federal Emergency Management Agency (FEMA)
regulations will not come into effect. As a result, a Floodplain Development Permit will not be
necessary before construction begins. However, the TCEQ Storm Water Program does stipulate a
Construction General Permit when more than 1-acre of land is disturbed in the construction phase. This
permit will require PAGGES Engineering to submit Storm Water Pollution Prevention Plans that specify
how erosion control measures will be implemented to avoid sediment transport during construction
stages. The following documents are listed by TCEQ for the purpose of environmental permitting and
they will be reviewed by PAGGES Engineering to determine their applicability to this project:

Application Distribution: Number of Copies Needed
Instructions: Use the table below to determine the number of applications needed for plan review. One original and one copy of the application, plus additional copies (as needed) for each affected incorporated city, groundwater conservation district and county are required. Linear projects or large projects, which cross into multiple jurisdictions, can require additional copies. Refer to the Groundwater Conservation Districts within the EAPP Boundaries Map found on the TCEQ website at: http://www.tceq.state.tx.us/compliance/field_ops/eapp/review.html
