Parcel and CAMA Data Improvement
This project helps towns update and align their property records, so parcel maps and assessment data are accurate, complete, and easy to use.
The Connecticut Office of Policy and Management has allocated $2 million in American Rescue Plan Act (ARPA) funding to support Connecticut’s Councils of Governments (WestCOG among them) in addressing parcel and Computer-Assisted Mass Appraisal (CAMA) data issues within their member municipalities. This initiative aims to improve the accuracy, completeness, and recency of parcel and CAMA data to ensure all municipalities have reliable and well-integrated property records.
A prioritization framework was established, focusing on recency, match rates, completeness of CAMA fields, and geometric quality of parcel data. The scope of work and framework are refined in discussions between OPM, COG GIS Coordinators, and municipal parcel / CAMA vendors. The highest priority is to ensure parcel datasets are up to date and that each CAMA entry has a corresponding parcel in the parcel layer. The secondary priorities are to ensure the completeness of CAMA attribute fields and the existence of parcel / CAMA data for every assessable property. The final objective will be to improve the geometric quality of parcels following recommendations from the GIS Office and GIS Advisory Council.
