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.
Dam Stabilization in Sensitive Aquatic habitat
Zara provided protected species relocation, biological monitoring, and adaptive management during emergency repairs to Spring Lake Dam, translating federal conservation requirements into practical construction controls.
Karst Resource Management along US 281
Zara provided karst, conservation, and regulatory expertise throughout the US 281 project lifecycle, helping TxDOT navigate sensitive karst resources from environmental review through construction.
US 190 Bridge Replacement: Mussel Relocation and ESA Consultation
Zara helped TxDOT keep the US 190 bridge replacement moving with mussel surveys, construction-phase relocation of more than 1,300 mussels, and consultation documentation that led to a USFWS conference opinion.
Bridging Infrastructure & Sensitive Resources at Redbud Trail
Zara Environmental LLC conducted multidisciplinary biological and geologic investigations to identify sensitive resources, inform bridge design, and support regulatory compliance within the Edwards Aquifer Recharge Zone.
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.”
