The following is a list of contractors for environmental, archaeological, and engineering services.   This list is not all-inclusive and concentrates on Philadelphia District boundaries covering Eastern Pennsylvania, New Jersey, Maryland, Delaware, and New York.  This list contains only firms who have requested listing.   The Corps of Engineers provides this list as a service to the public and updates it as workload allows.   No recommendation or guarantee of competence or experience is implied by this listing.  The Corps of Engineers neither endorses nor accepts responsibility for work performed by any firm on this list.   We suggest that prospective clients ask for credentials before contracting for professional services.

Note: The Corps is the final authority with respect to the delineation of wetland areas and other waters of the U.S., as well as the determination of activities requiring DA permits.  All wetland delineations must be conducted and documented in accordance with the "1987 Wetland Delineation Manual."   The Corps will review all preliminary jurisdictional determinations to verify their accuracy.
