Constraint maps/hazard drawings

View hazards and see which areas of a parcel are buildable by viewing the constraint maps created through the Buildable Area Analysis.

View the buildable area constraint maps

Running the Buildable Area Analysis task on a project will create constraint maps for each parcel.

As the analysis runs, the constraint maps will load into the map automatically.

  • Turn the constraint maps on and off via the map toolbar "drawing" menu > Load/hide all drawings

Don't see the constraint maps/hazard drawings displaying on a project? Toggle them on via the map toolbar > Drawings> Load all hazard drawings.

Hide/show different constraint map layers

The Constraint Map legend can actually be used to show/hide different constraint map layers.

  • Hide a constraint map layer by clicking on the layer name in the constraint map legend.

  • To hide all layers at once, click the 'Constraint Map' text at the top of the legend to auto-hide all the layers. From there, you can re-display individual layers, like the Buildable Area Layer

Reviewing the hazards/buildable area

Each hazard is represented by a different color shading on the map.

  • Click on a hazard on the map to read more information about the hazard and that specific parcel

Clicking on a color within the constraint map will pull up more details

Review buildable area analysis settings/setbacks

Need to see what settings/inputs were used to generate the constraint maps on a project? The metadata is stored in the buildable area constraint map.

  • Make sure the constraint maps are turned on/visible on the map

  • Click any of the buildable area analysis polygons on the map

  • In the pop up about the Buildable Area, scroll down to the bottom of the pop up to see list of settings and values from the form that were used for this run.

    • Note: units are listed in meters
