EAS is dedicated to providing services in a professional, timely, cost-effective manner. Our experience in the mentioned industries has led to special insight into the needs, requirements, and standard protocols associated with the environmental evaluation process

Natural Resources Management

Whether it is surveying for protected species, monitoring construction, or restoring habitat, EAS has a diverse and experienced group of natural resources management specialists to complete the task. Our comprehensive in-house biological staff can prepare the simplest habitat assessments and endangered species surveys to the most complex endangered species permits. Our expertise with Habitat Conservation Plans and Section 7 Consultation has helped Federal, State, Indian, municipal agencies, and private development clients meet their planning objectives. We have also provided project planning and permit facilitation to residential and commercial developers, resort and golf course sponsors, energy power suppliers, public agencies, and the military.

Our Natural resource services include:
  • Biological Assessments
  • Construction Mitigation
  • Endangered Species Surveys

  • Resource Management Plans
  • Sensitive Species Investigations
  • Special-Status Species Surveys
  • Wetlands Delineation Permitting

Cultural Resources Management

We assist clients in preserving the prehistoric and historic cultural heritages of regions undergoing development. We achieve this by conducting preconstruction site assessments, literature and archival record searches, field surveys, and, if necessary, subsequent testing and recovery programs. We can also conduct paleontological assessments of properties to determine the potential for significant fossil remains. First we determine the types of sediments, their potential for containing fossils, and the approximate depth of the deposits. We can then make recommendations for further work ranging from field surveys for surface finds, paleontological monitoring programs, and fossil salvage plans. Mitigation monitoring of earth-moving construction activities ensures significant fossils and artifacts encountered will be appropriately recorded, collected, curated, and documented in accordance with Federal and State regulations, professional guidelines, and Local Government requirements and recommendations.

Services in this discipline include:
  • Archaeological Surveys, Testing, and Salvage
  • Architectural Historic Resources
  • Construction Monitoring
  • Cultural Resources Evaluations (Section106)
  • Curation and Documentation
  • Field Surveys
  • Literature and Record Searches
  • Paleontological Surveys and Salvage
  • Native American consultation
  • Salvage of Fossils, Artifacts, and Eco-facts
  • Site Assessment Prior to Construction
