Data

Data has been broken into smaller files for ease in editing. In “data/RPC” all the zoning files are split out into the Regional Planning Commissions (RPC). This geojson can be explored in the abbreviated viewer on the homepage of this site or downloaded for further analysis.

There is also a state-wide single file, “data/State of Vermont”, this is not the preferred way to update the files but rather for analysis.

Collection Timeline and Data Error Warning

This effort is a collection of teams which includes volunteers, interns, and students. This was done over a year period from 2023-2024 and during this time updates to the zoning codes have already made some of this data inaccurate. It is likely that this data will only be updated once a year at most so this data can be out of date. It is also possible that the regulation from the State of Vermont may not be reflected in town zoning just due to the time it takes to update and comply with legislation and the very limited capacity many of these towns have to complete that work.

Fields

There is a large number of fields, the naming and in some cases the implementation will differ from the National Zoning Atlas. We will also only be maintaining a subset of these dataset over time and markers will be added to the list below when that has been determined.
