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.

I am writing to thank you (Hank) and STONE for the services you performed for the site civil design (CC-plans and Site Compliance Plan), preparation of construction documents and specifications, and obtaining approvals through the City of Columbus for our new V&S Columbus Galvanizing LLC facility. Your ability to meet our tight schedule, stay within engineering construction budgets, and provide a quality end product was critical to the completion of the site work for this project.
