Coastal Information Management System (CIMS)

The CPRA Coastal Information Management System (CIMS) is the central access point for additional information on the CPRA’s protection and restoration projects and ongoing initiatives. CIMS includes a series of interactive GIS-based maps, a tabular database with a variety of project and monitoring data available for download, and a document library containing project reports and associated information. The information on this website  is intended for general informational purposes only and should not be considered authoritative for any other uses. The Coastal Protection and Restoration Authority does not warrant or guarantee its accuracy, nor does the CPRA assume any responsibility or liability for any reliance thereon.

Coastwide Reference Monitoring System (CRMS)

CRMS is a multiple reference approach that uses aspects of hydrogeomorphic functional assessments and probabilistic sampling. This approach includes a suite of sites that encompass the range of ecological conditions for each stratum, with projects placed on a continuum of conditions found for that stratum.
