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.

“STONE Environmental was a pleasure to work with. From the planning process to our onsite visit. They knew exactly what we wanted and were able to deliver in a timely fashion.  The on-site field engineer was very resourceful and her attention to the small details was phenomenal. I will be sure to use STONE on all my future environmental surveying projects.”
