Stream Restoration – Delaware, Ohio
STONE completed ecological and engineering/design services for a stream stabilization project at this condominium development. STONE completed a topographic survey, hydraulic modeling of the stream, creation of conceptual design alternatives, a Preliminary Jurisdictional Wetlands/Waters delineation, associated waterway permitting including a Nationwide Permit (NWP) from the United States Army Corps of Engineers (USACE) and a Director’s Authorization (DA) form the Ohio Environmental Protection Agency (Ohio EPA), design and construction plans, and assisted in contractor selection for the project. STONE worked closely with the client on multiple aspects of the project from start to finish. The project was located in an ineligible watershed for automatic 401 Water Quality Certification (WQC) for a NWP, so a Director’s Authorization from the Ohio EPA was necessary to obtain in order to perform the stream stabilization work. STONE provided the client with an on-site restoration riparian planting plan as an alternative to avoid the purchase of more expensive stream mitigation credits.
