At Spirit we have a leading team of consulting professionals with experience in regulatory permitting under Section 404 of the Clean Water Act (CWA) and Section 10 of the Rivers and Harbors Act. We thoroughly understand the objectives of the CWA. We are experts with United States Army Corp of Engineers (USACE) permitting, as well as state specific wetlands and waterbodies regulations. Our team routinely provides our clients with pre-project consulting, wetlands and waters surveys, project permitting, and post-project mitigation and monitoring. We fuse together our excellent working relationships with regulatory agencies and our detailed focus on the specific needs of each client to ensure a smooth transition through the permitting process.
