Geographic Information Systems (GIS)

Addison County Regional Planning Commission provides mapping services to its member municipalities and in support of its regional planning responsibilities. Geographic Information System (GIS) software is used to develop maps and undertake spatial analysis.

A geographic information system integrates hardware, software, and data for capturing, managing, analyzing, and displaying all forms of spatially referenced information. A GIS allows users to view, understand, question, interpret, and visualize data in many ways that help to reveal relationships, patterns, and trends. A GIS helps you answer questions and inform decision-making by looking at your data in a way that is quickly understood and easily shared.

We provide GIS services to state and regional partners, municipalities, private consultants and individuals on projects that involve transportation, land use and natural resources planning, emergency planning, and community and economic development.

For any questions about our GIS services, data, prices or general GIS information, please contact Kevin Behm, Assistant Director/GIS Manager.

Community Build-Out Analysis Software

The Community Build-Out Analysis program is designed to help communities project the future consequences of their zoning.

The program is implemeneted as an ArcViewproject (Version 3.1 and above – it will not work in ArcGIS).

It functions as a simple acreage based build-out – that is, zoning district acreage is tabulated by parcel to determine development density. House point locations are used to determine existing development.

Potential development is calculated from parcel acreage that meets the minimum lot size for the respective zoning district.

The build-out density can be modified by changing the minimum lot size or incorporating natural resource layers such as wetlands or slope.

A tabular report is provided by zone listing existing and potential development as well as associated acreage.

The Community Build-Out Analysis program is part of the larger Community Planning Tools Demonstration Project funded from Vermont Senator Patrick Leahy’s office through the State USDA Office. The funds were administered by the Center For Rural Studies at the University of Vermont.

The Addison County Regional Planning Commission proposed the development of a build-out program in response the need of the Lewis Creek Association to project development scenarios in the Lewis Creek watershed.

Software design and development was undertaken by C. L. Davis Consulting Associates, Ltd of Weybridge, Vermont.

The Lewis Creek watershed comprises parts of several communities south of the Burlington, Vermont, metropolitan area that are subject to development pressures. The Lewis Creek Association intends to assist these communities in formulating planning and zoning policies that consider the natural habitats and water quality aspects of development within the watershed.

For any questions about the Community Build-Out Analysis software, please contact Kevin Behm, Assistant Director/GIS Manager.

GIS data sources

Statewide data sets are available through the website, www.vcgi.org, which is run by the Vermont Center for Geographic Information (VCGI). The data warehouse at the VCGI has a set of categories of available GIS data. The site’s “how-to page” has great information on how to download data. Popular datasets include roads, e911 address locations, public conserved lands, etc. Digital aerial photography is also available.
