How to submit service territory data (GIS) updates:
Please use the form linked below and attach your data files to the form for processing.
Important Notice to all members who send in GIS updates:
If you send in territory data that is not in a typically accepted format (KML or KMZ) or if you send in additions to coverage (versus complete replacements) this requires additional manual work by our GIS team to produce a file that is compatible with our system and you will be billed for any time required to accomplish this. GIS billing rates are currently $220/hr.
To keep costs at a minimum for members, we suggest sending in complete replacement files in KML/KMZ format instead of additions. Members also have the ability to self-upload files by using AuthorityViewer in our Utility Portal. Please contact the call center if you would like more information on that.
