Zara Projects

Texas-Sized Case Studies in ESA, TCEQ, and Natural Resource Management.

From initial planning to project completion, early collaboration with our experts can save both time and money. By anticipating environmental requirements, whether it’s assessing macroinvertebrate communities for critical water supply infrastructure, monitoring bat colonies during major bridge replacements, relocating freshwater mussels in deep urban rivers, or guiding complex karst permitting for highway expansions, we provide the foresight needed to keep projects efficient, compliant, and cost-effective. These case studies show how early involvement can turn potential challenges into opportunities for smoother, more effective project delivery.

What people are saying about us

“During construction of a project in San Antonio, we uncovered a unknown karst feature near the mapped limits of the Robber Baron Cave. After one call to Zara, we had specialists in the feature who were able to evaluate, monitor, sample for endangered species and provide a closure plan. We were very pleased with Zara’s quick response and expertise which allowed construction to proceed according to schedule.”
