Cultural Resources

For over 10 years, IES has worked under contract and in coordination with numerous political subdivisions, federal agencies, and private sector entities to provide assistance in navigating the obstacles surrounding cultural resources requirements under Section 404 of the Clean Water Act (CWA), National Environmental Policy Act (NEPA), Sections 106 and 110 of the National Historic Preservation Act (NHPA), Antiquities Code of Texas (ACT), and Texas Health and Safety Code.

While the cultural resources team specializes in rapidly conducting archeological surveys and report preparation for clients needing to maintain compliance with state and federal cultural resource regulations throughout Texas and Oklahoma; IES is also capable of providing NRHP testing and mitigation services. The team has an expert Geographic Information Systems (GIS) staff capable of compiling and manipulating spatial data to produce detailed cultural resources probability models and professional-grade mapping.

IES believes that by becoming aware of cultural resources, and the potential pitfalls surrounding them, parties can more efficiently navigate the compliance process and complete projects without further delays. For this reason, IES spends a great deal of time and effort coordinating with their clients regarding the process, the compliance requirements, and what the best, most practicable options are moving forward. Through our detailed understanding of cultural resources regulations, and a developed rapport with state and federal agencies, IES has the expertise needed to effectively navigate the regulatory compliance world.
