WSSI has provided a full range of natural and cultural resources services along 60 miles of interstate to relieve traffic pressure in northern Virginia: 36 miles along I-95 & I-395; 11 miles of I-495; and 13 miles of I-95 in Fredericksburg. WSSI has studied and survey-located Waters of the U.S.; evaluated repercussions for threatened and endangered species; documented cultural resources; procured impact authorizations; secured compensation for stream and wetland impacts through off-site stream restoration and mitigation bank credits; and provided Clean Water Act compliance services for these Virginia Public-Private Transportation Act projects.
The Challenge
These high-profile projects required reliable natural and cultural resource studies; experienced guidance in reducing impacts and creative compensation solutions to facilitate impact permitting; and committed project compliance guidance and inspections. Foresight and experience are critical for effective and efficient work in these tightly constrained corridors along active and heavily traveled highways.
As designs changed during the project, WSSI had to be able to mobilize quickly for additional field work and permit modifications to keep the projects moving forward.
