In 2011, CZM updated the Designated Port Area (DPA) boundary maps and descriptions. The previously effective maps were available in hard-copy format only, and, in some cases, boundaries were ambiguous. CZM went through a thorough process to transform these hard-copy maps into digital format. During this process, slight modifications were made to facilitate boundary identification, primarily to align the boundary with the most recent assessors' parcel maps or National Oceanic and Atmospheric Administration nautical charts. Since 2011, routine updates have been made and publication dates are provided in each boundary map and description.
For a complete listing of the information CZM provides on DPAs, see the Designated Port Area Index Page.
