Hi @MelanieNeedle ,
Happy New Year, and thanks for your question.
Advanced overlay settings
The advanced overlay settings let you configure how the zoning parameters configured on an overlay boundary interact with zoning parameters of the underlying zoning boundaries.
By default, a zoning parameter configured on an overlay boundary replaces the zoning parameter of the underlying zone.
The remaining 4 options have the following effect:
- Maximum: the zoning parameter on the underlying zone is only replaced if the corresponding zoning parameter on the overlay boundary is higher than the one on the zone.
- Minimum: the zoning parameter on the underlying zone is only replaced if the corresponding zoning parameter on the overlay boundary is lower than the one on the zone.
- Add: the zoning parameter value on the underlying zone is added to the corresponding value on the overlay boundary.
- Subtract: The zoning parameter value on the overlay boundary is subtracted from the corresponding value on the underlying zone.
Number of dwelling units as reported in the building regulation panel
The number of dwelling units as reported in the building regulation panel is driven by two factors:
- The parcel area
- The applicable "Dwelling units density" value for the given parcel. This value can either be configured on the zoning, overlay or parcel level. See Zoning regulation management in our docs to learn more about where you can configure zoning regulations.
Generally, a zoning parameter configured on an overlay replaces the corresponding value of the underlying zone. Any zoning parameter configured on the parcel level, replaces the corresponding value of the underlying zone and overlay.
Effect of overlays on metrics
Would you mind providing an example of what you mean by "what effect the overlays have on metrics"?
In case of further questions, please don't hesitate to reach out.
Thanks,
