US 2020 Census’ Participant Statistical Areas Program (PSAP)

Every ten years, the Census reviews its existing boundaries. These boundaries serve as the foundation for tabulating statistics on socioeconomic data. The Census has designated WestCOG as the PSAP Primary Official (PPO) to oversee Census Boundary Updates for Fairfield County. WestCOG will be working with its member communities, neighboring COGs, and CTDOT to perform these updates. WestCOG has identified two tasks to work on during this process. Updating Census Designated Places (CDP), and reviewing existing census block-groups and tract boundaries.

CDP Update: WestCOG has developed a methodology to update and delineate new Census Designated Places (CDP). CDPs are currently used sparingly or not at all within CT. CDPs provide detailed information for a neighborhood, downtown district, or village that may be difficult to capture using census block groups. The methodology can be downloaded here: CDP Methodology

BG and Tract Review: WestCOG will be working with CTDOT and muncipalities to for requested edits to census boundaries. The goal is to develop boundaries most useful for analytics, regional studies,and traffic modeling. WestCOG is working on a methodology to standardize its role in this review/edit process.

Regional GIS Grant

Initial Grant Award

In 2012, WestCOG’s predecessor, SWRPA, received Regional Performance Incentive Program (RPIP) funds to develop a regional GIS program to develop a regional GIS Program which would host extensive data resources such as imagery, lidar, contours, and planimetric data. With consolidation of the State’s planning regions, the project was extended to the entire Western Connecticut Planning Region, and was expanded to cover additional tasks (in the areas of property assessment and records).

GIS Data Acquisition

Flight Data for Southern Towns: The project launched in 2014 when the vendor, Kucera, was selected to generate:

  • High resolution imagery (3”)
  • Oblique Imagery
  • Lidar, Elevation Data
  • Planimetrics

This data collected was known as the 2014 Kucera Flight Data.

Flight Data for Northern Towns: RPIP funds were utilized to develop planimetrics data for the 10 northern towns in the WestCOG Planning Region. This effort was performed in 2016 using data from a state flyover performed in 2016.

Planimetrics Update for Developing Areas: In areas with high development activity (Stamford, Norwalk, and along Route 1), remaining grant funds were used to update planimetrics data to match 2016 state flight data. This work was completed by Sanborn in 2018.

Axiomatic Reports

Axiomatic, in partnership with WestCOG and its members, conducted a study of opportunities for regional cooperation in property assessment and records, including the viability of a regionalized Real Property Computer Assisted Mass Appraisal (CAMA) system.

Regional CAMA Study: The study found that the cost savings of a Regional CAMA Service were negligible due to the diversity in property tax base, software, and schedules within the Region. The report did identify four workflow efficiency projects:

  • Regional GIS Parcel-CAMA web viewer
  • Personal Property E-File
  • Automated Deed Integration
  • E-File for Exemptions

This report is explained in detail in the Existing Conditions & Initial Recommendations Report.

Two follow-up reports were developed to facilitate implementation of these projects:

Regional GIS Parcel-CAMA Study: This service would develop a sustainable approach to collect and standardize parcel and CAMA data across the Region, and to share these data via the web. The report provides a breakdown of cost benefits, best practices, and an implementation strategy.

Following this report, WestCOG has performed a Request for Information (RFI). Following the RFI, WestCOG Foundation Inc. is now in the middle of a Request for Proposals (RFP) to identify vendors to provide this service. This project is expected to commence in 2019.

This project is explained in detail in the Regional GIS Web Application Recommendations Report.

Regional Recommendations Study: This report outlines the cost, benefits, and steps for implementation for three projects:

  • Personal Property E-File (Completed)
  • Automated Deed Integration (In Progress)
  • E-File for Exemptions (Pending)

These projects are explained in detail within the Regional Recommendation Prioritization Report.
