WSSI emerged from The Michael Rolband Company, a real estate development firm which specialized in environmentally-challenged sites. In 1991, the organization incorporated under the new name of Wetland Studies and Solutions, Inc. to reflect our shift in focus to Clean Water Act permitting and the regulatory requirements of state and local water protection efforts, including Virginia’s Chesapeake Bay Preservation Act. WSSI became a Wholly Owned Subsidiary of The Davey Tree Expert Company in 2014.
