Adding or editing counties

Last updated: 2026-04-01

Designers must enter information about the county(s) in which the work is to be performed. Complete the required fields, using the field tool tips or the Project summary data fields table for guidance. Select the Counties tab to add, edit, or delete counties within the project limits.

Tips:
  • Click on the thumbnail images below to expand and view the content.
  • County information appears in FIIPS under the General tab.
  • For statewide or region wide projects, use a code from the list below.

Requirements: The sum of the county percentages on a project should always equal 100%; therefore, if counties are added or deleted, adjust the values in the county percentage fields so that the sum is 100%. Validation takes place during project level validation and not when the component is saved.

  1. From the Project Summary Counties tab, click <New> to add an additional county.
  2. In the County ID field, begin typing the county name or the 4 digit county code (e.g. Manitowoc or C036) and the county will appear. The county selected must match what appears in FIIPS.
  3. In the Pct field, enter the percentage of project length for the selected county.
