PROJECT DETAILS
- Project Name Advancing Stream Assessment: A Unified Methodology for Perennial Stream Condition Evaluation
- Category Wetland Delineations
- Location Newport News, Virginia
Stokes Environmental Associates, Ltd. (SEA) provided environmental research, studies, documentation, interagency coordination, and monitoring services for projects requiring perennial stream assessments for RPA determinations, Unified Stream Methodology (USM) assessments for stream mitigation requirements, and has the ability to assess stream health based on the quantity and range of macrobenthic species present in a stream reach.
The client needed to obtain a wetland permit for construction of two roads across a stream to enable a residential development which contained non-tidal stream wetlands.
Specific tasks included:
- Conducting a wetland delineation to identify wetlands on-site and their classification.
- Conducting a perennial assessment of the streams to determine the break between perennial flow and intermittent flow regimes.
- Evaluate the proposed streams to be crossed using USM to determine mitigation requirements that would be required by the DEQ permit.
- Coordinate with the US Army Corps of Engineers (COE) to verify the extent of wetlands and streams on-site.
- Prepare a joint permit application (JPA) for the project, and coordinate with the COE and DEQ to obtain the required permit.
Stokes Environmental provided key environmental expertise throughout the project life from initial site feasibility evaluation through completion of environmental reviews and permit issuance.
SEA evaluated streams for impacts from watershed pollution based on the macrobenthic organisms found and their known tolerance of pollution.
This work resulted in a permit to construct roads across a jurisdictional stream, and enabled multi-family residential development.
