Member Mapping

Member Mapping is a requirement under PA Act 287 of 1974, as amended by Act 50 of 2017. 

All underground facility owners in Pennsylvania must participate in the Pennsylvania One Call System's Member Mapping Solutions.

Member Mapping is an online tool developed by Pennsylvania One Call System to refine member facility owner's notification areas by using map objects instead of municipal boundaries. Member Mapping is available to all member facility owner at no charge.

Member Mapping is designed specifically for member facility owners who do not have the resources for an internal GIS or CAD system.  The online tool allows for you to import your center line files for your notification areas, bypassing and streamlining the effort to draw notification areas on a municipality by municipality basis.

How Member Mapping Works

Pennsylvania One Call System notification requests have defined excavation sites drawn on maps 99.9% of the time, called the ticket notification area. A facility owner uses Member Mapping to identify where they wish to be notified for locating their underground facilities, referred to as the member notification area

The Pennsylvania One Call System software compares the ticket notification area against the member notification area to identify which notifications should be transmitted to a facility owner who uses Member Mapping to define their areas.
