Manually Remove Hazards

Manually remove hazards from the buildable area using the composite geometry tool.

Overview of process

  • Navigate to asset page

  • Create additional polygon (copy from layer) or draw using drawing tools

  • Right-click hazard to create buffer if desired

  • Ctrl+Click each hazard and the buildable area polygon

  • Hover over “Design” and select “Composite Geometry”

  • Click buildable area once in the top right menu to “Include” it

  • Click each hazard twice to “exclude it”

  • Click “Build”

  • Click “Update Buildable Area”

Detailed workflow

Go to the parcel asset detail page

  • From the project map, click on the parcel on the map

  • In the parcel pop-up, click 'Select'

A new page will open with the parcel asset detail page info:

Use drawing tools to trace out hazard/copy hazard from layer

Turn on the drawing tools > map toolbar > drawing > user drawing tools

  • Trace out the hazard using one of the drawing tools (e.g. draw a polyline to mark the location of a pipeline).

  • If using a layer, click on the object in the desired layer and choose 'copy' to save the hazard to the map as a drawing

Add hazard setback/buffer (if app.)

  • To add a buffer to the hazard, you''ll need to right-click the hazard drawing on the map.

    • If the buildable area/parcel polygons are in the way, you can temporarily hide them so that you can access the hazard drawing below.

    • To hide objects on top of the drawing, click the buildable area polygon and temporarily hide it by clicking the 'Visibility' button. Repeat with the parcel polygon if necessary.

  • Right-click the hazard drawing on the map and in the pop-up input a desired buffer/setback.

    • Click the Create button to create the buffer

This will create a buffer/setback around the hazard:

Repeat this process to mark out any desired hazards and apply a hazard setback/buffer as needed.

Mulit-select the hazard buffer(s) and buildable area polygon in map sidebar

In order to run the composite geometry tool, select the hazard buffer and the buildable area polygons so that they are listed in the map sidebar:

  • Use a multi-select click to select each of the hazard buffers and buildable area analysis polygons on the map.

    • Hold down CTRL key (Macs: Command key) while clicking each object with cursor to select it in the map sidebar.

    • If the buildable area polygon was previously hidden - turn it back on (drawing > click on the buildable area listing in the drawings menu) - and then continue to hold down CTRL while clicking the buildable area polygon.

If buildable area polygon was previously hidden. Re-display it using the drawings menu.

Once the objects are selected, they will be listed in the map sidebar like this:

Run composite geometry

  • Click design

  • Select build composite geometry from the design dropdown menu

This will display bubbles next to each polygon in the sidebar:

  • Click the bubble by the buildable area polygon 1x to 'include' it

  • Click each hazard (or the hazard buffer if one was applied) 2x to 'exclude' it

  • Click 'Build'

Click 'update buildable area' button in pop up

  • After clicking 'Build' in the previous step, a pop up will appear on the map

  • Click 'Update Buildable Area' to finish updating the buildable area polygon and calculated area

This will finish updating the buildable acreage calculation and the new buildable area will be displayed on the map (white border to indicate manually modified)
