Big Dry Creek Pilot Project Wetland Permitting

Over the past six months, Andrew Earles and Natalie Phares have been working with adjunct scientist Blair Leisure of IRIS Mitigation on wetland and floodplain permitting for the Big Dry Creek Pilot Project in Thornton, Colorado. The pilot project involves stream restoration and improvements including a pedestrian bridge, trails, drop structures and other ecological and recreational amenities.

The project will help to address erosion and channel migration using naturalized channel design techniques. Andrew and Natalie have been working on a no-rise certification for floodplain permitting, and Blair has been handling permitting for wetlands with the United States Army Corps of Engineers (USACE). The project team received notification from the USACE in late May that the project can be covered under a Nationwide Permit No. 27 (Aquatic Habitat Restoration, Establishment and Enhancement Activities). This is a significant milestone for permitting of this project.

On floodplain permitting, Andrew and Natalie have been working with Drake Ludwig of Matrix Design Group and Brandon Parsons of THK Associates. WWE thanks Kevin Shanks and Brandon Parsons of THK and Paula Schulte, Jim Kaiser and their colleagues at the City of Thornton for the opportunity to assist on this project.
