1. Wetlands Delineation and Assessment 1.1. Wetlands delineation and assessment shall be completed by a certified soil scientist to delineate and assess the presence of federal and state inland wetland resource areas within 150 feet of the culvert crossing as shown on the above figure noting approximate project area limits. 1.1.1. Federal wetland resources shall be delineated in the field according to the U.S. Army Corps of Engineers (USACE) 1987 Wetland Delineation Manual and the USACE 2012 Interim Regional Supplement to the Corps of Engineers Wetland Delineation Manual: North central and Northeast Region. 1.1.2. Connecticut state inland wetlands, if any, shall be delineated based upon soil type as outlined in Section 22a-38 of Chapter 440 of the General Statutes of Connecticut; defining wetland soils as either: poorly drained, very poorly drained, alluvial, or floodplain soils. 1.1.3. Identification of watercourses, as regulated by Connecticut, shall be based upon the definitions contained in Section 22a-38 of Chapter 440 of the Connecticut General Statutes of Connecticut; including the following hydrological systems under the term “watercourse”: rivers, streams, brooks, waterways, lakes, ponds, marshes, swamps, bogs, and all other bodies of water, natural or artificial, vernal or intermittent, public or private. 1.1.4. Prior to the delineation fieldwork abutters shall be notified prior to accessing all private property necessary to perform the wetland delineation. 1.1.5. Flagging shall be placed in the field to denote federal and state inland wetland and watercourse boundaries within the project area. 1.1.6. Delineated wetlands shall be classified by vegetation type according to the U.S. Fish and Wildlife Service (USFWS) National Wetlands Inventory (NWI) classification system, Classification Method for Wetlands and Deepwater Habitats (Cowardin et. al., 1979).
