Understanding the Environment, Accounting for Regulations

Watershed scientists use the latest scientific methods to assess wetlands, streams, wildlife, fish, and trees and provide accurate documentation. We can help design innovative, functional, and attractive mitigation and restoration plans that augment the property and ecological functions, and meet regulatory requirements, from permit submittal through construction.

Watershed also leads the field in non-traditional methods of mitigation, including mitigation banking, in-lieu fee programs, and restoration credits.
