Local conditions
Environmental conditions in San Antonio
San Antonio's growth corridor stretches across the Balcones Escarpment and into the Edwards Plateau, putting new development on ground that has supported ranching, light industry, military installations, and petroleum distribution for well over a century. That history matters at closing and during construction: undisclosed releases, recognized environmental conditions, and unexpected subsurface contamination can halt a transaction, trigger regulatory involvement, or add unbudgeted cost to a project schedule. Our environmental services team gives contractors, developers, and engineers the documentation and field support needed to move through those risks with clarity. We conduct Phase I and Phase II Environmental Site Assessments following ASTM E1527-21 and ASTM E1903-19 protocols, and we provide construction-phase environmental monitoring and compliance support so that project teams stay ahead of issues rather than reacting to them. Coverage in San Antonio is dispatched through our Austin regional hub.
Much of the San Antonio metro sits on or near the Edwards Aquifer recharge and contributing zones, making subsurface investigations and spill-risk documentation a particular concern for regulators and lenders alike. The region's expansive clay soils and alternating wet-dry cycles also influence the behavior of residual contaminants and the planning of soil-sampling programs.
FAQ · San Antonio
Our San Antonio site is near an Edwards Aquifer recharge zone. Does that change the scope of a Phase II investigation?
Proximity to the Edwards Aquifer recharge or contributing zone typically draws closer scrutiny from the Texas Commission on Environmental Quality and can influence lender requirements. While ASTM E1903-19 governs the Phase II scope, your environmental professional will likely recommend tighter sampling intervals, additional analytes, and coordination with applicable TCEQ guidance to address the heightened sensitivity of the receiving environment.
San Antonio has a significant concentration of former military and defense-related properties. What should we watch for during due diligence on those sites?
Former military and defense-adjacent properties in the region can carry recognized environmental conditions associated with fuels, solvents, munitions-related compounds, and industrial coatings. Under ASTM E1527-21, a thorough records review and site reconnaissance must evaluate historical aerials, Sanborn maps, and regulatory databases. Where RECs are identified, a Phase II under ASTM E1903-19 targeting site-specific contaminant classes is the appropriate next step.
What environmental monitoring support do you provide during the construction phase once grading and earthwork begin?
Construction-phase support can include soil screening during grading using photoionization detection, documentation of suspect material encountered during excavation, coordination with the project environmental professional of record, and field logging to support regulatory reporting. If previously unidentified impacted material is uncovered—a common occurrence on infill sites—having a qualified technician on-site allows the project team to respond with documentation rather than delays.
