Adds - Adds should be applied when you only want to add new coverage to your 811 service areas. The mapping file may include individual additions or the entire code’s coverage area. GIS staff will not delete data from your code’s current coverage.
Deletes - Deletes should be applied when you only want to delete coverage from your 811 service areas. The mapping file you submit should include only those areas that you want to remove. If you need to remove an entire service area, please note "full code delete" under the additional information.
Full Replacement - For a Full Replacement, please submit a mapping file representing the entire area for which you want asset protection. Essentially you are swapping out what is currently registered and replacing it with this new file you have provided. A Full Replacement requires you to indicate a reason for deletions on the Member Mapping Submission Form, so if you do NOT intend to delete any coverage areas, please request Adds instead.
