Submitting Your Project Plans Electronically

Learn how to submit your engineering plans electronically with our electronic data transfer process.

Builders and developers are required to submit engineering plans for projects electronically after submitting a request for new natural gas service or line extension.
The data is used to support your individual project in order to help streamline development of construction plans for your gas service installation.

How to Prepare Your Files

Files that use the latest version of digital Computer Aided Design (CAD) with an organized identifiable and isolatable layer structure are required. As an alternative, Geographic Information System (GIS) files are also acceptable.

Please supply an organized identifiable and isolatable layer structure for each of the property maps.  Maps should be identified as recorded, tentative or other. The list of features below is what is needed at a minimum within the submitted files. For a full list of minimum required features see CAD Minimum Requirements.
  • Building footprints with numbers and names
  • Driveways or easements indicating private property
  • Lot lines with lot numbers
  • Public and private streets with names and width
  • Public utility easements
  • Record map boundary (include record map numbers, bearings and distances)
  • Right-of-way limits (flood control, railroad, etc., with names and width)
  • Street centerlines

Acceptable CAD and GIS File Formats (listed in order of preference):

  • CAD
    • MicroStation (.dgn) version J or lower
    • AutoCAD (.dwg) Version 2014 or lower
    • Universal format (.dxf)
  • GIS
    • Shapefile (shp)
    • Database file (dbf)
    • Personal Geodatabase file (PGDB)
    • Projection Format file (prj)

Non-Vector (scan) Submittals

Scanned copies of maps are not encouraged but may be submitted for smaller sized developments where a digital CAD or GIS file was not created and only copies of pre-existing maps are available. The submitted maps must contain the minimum requirements stated above. All necessary Landbase information pertaining to the scope of the project must be legible.

For a full listing of acceptable scanned documents and information needed within non-vector files please see Non-vector Minimum Requirements.
