Refine a Boundary with Drawing Tools
Use drawing tools to clip, expand, or reshape a boundary when parcel selection alone isn’t enough.
Open Drawing Tools from the taskbar and create a new Project.
Use Add Polygon (or any shape) to draw the exact area you want to represent.
Return to the Custom Boundaries list, edit the record, and click Update Geometry.
Select Match to Custom Polygon, choose the project you just drew, and confirm.
Save changes and Zoom To your updated site to review the new shape.

Add progress notes (e.g., "mailer sent 5/1") to track outreach efforts.
Toggle Show All to quickly list every boundary and jump between sites.
