The Massachusetts Coastal Infrastructure Inventory and Assessment data was developed for Massachusetts Department of Conservation and Recreation (DCR) by Bourne Consulting Engineering. The data is in ESRI personal geodatabase format and includes coastal structures along the coast of Massachusetts represented by line features with attributes containing details of their condition. The attributes include location, photos and historical permits and drawings. See http://www.mass.gov/eea/agencies/czm/program-areas/stormsmart-coasts/seawall-inventory/ for further information.
