Environmental Engineering




Environmental Engineering Services


RDA is an expert in providing NEPA documents and state environmental impact reviews, wetland permitting, stream and wetland mitigation and restoration planning, and the coordination with cultural and natural resources agencies needed to support these processes. We regularly use risk communication techniques to support public participation and outreach, and are dedicated to caring for our clients. With many of our designers LEED-certified, and all designers fully knowledgeable in local, state, and federal environmental regulatory requirements, we assist our clients to plan and develop environmentally sound and sustainable projects.

RDA Environmental Engineering Services

  • National Environmental Policy Act / state-equivalent documentation
  • State / federal wetland & waters delineation and permitting
  • Stream & wetland restoration
  • Archaeological surveys
  • Stormwater management & permitting
  • Public & agency participation/outreach

RDA’s multidisciplinary staff works closely to understand the engineering versus environmental constraints of any undertaking, and achieve balance between negative environmental effects and the project’s purpose. We work with all stakeholders to find practicable solutions to conflicts between environmental resources and project viability. While primarily a Virginia firm, our environmental projects have taken us well beyond Virginia’s borders.

Additional Environmental Engineering Services

  • Wetland delineation and permit documents for numerous projects ranging in size from small site developments to over nine miles of new roadbed
  • Environmental impact documents for military and non-military construction, utility privatization, roadway improvement projects, multi-purpose trails, and security operations training
  • Stream and wetland assessments, restoration designs, and construction oversight using natural channel design and Rosgen principles

We have provided these services for private developers, utility companies, local jurisdictions (the cities of Manassas and Fairfax, and Prince William, Stafford, Fairfax and Loudoun Counties), GSA, Army, Navy, Marine Corps, Customs Border Protection, the Eastern Band of Cherokee Indians, National Park Service, and the Virginia DOT / FHWA.
