NAACC Culvert Inventory

The North Atlantic Aquatic Connectivity Collaboration, also known as NAACC, is a northeastern regional program that has created a protocol for inventorying culverts. This protocol takes into account many aspects of each culvert inventoried, and gives them a score. Attributes assessed include condition, height, width, dry passage, barriers, and more. The goal is to create a database for all these culverts that is easy to access and usable to several agencies. With this database, we hope to not only improve wildlife connectivity issues, but also alert town, county, and state highway garages to culverts that may be undersized, in poor condition, or may cause concerns during future storms.
