Each provider listed is coded only for the wetland-related services they offer. The codes are assigned based on information furnished by the provider. If difficulties were encountered in determining what services were offered, then no code was assigned. Users of this list should always contact providers directly for a full and complete explanation of services offered. The codes are:

A: Construction/Contractors
B: Environmental Assessment
C: Design and Engineering
D: Mapping
E: Mitigation
F: Regulatory and Permit Coordination
G: Survey

Additions/revisions to the list will be processed upon receipt of a written request and appropriate documentation. Requests should include a summary description, in one page or less, of the wetland related services offered in the areas of: wetland delineations; functional analysis (e.g., WET and HEP); mitigation; and regulatory and permit coordination.
