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 an application for a new natural gas line and being notified which SoCalGas® Planning Representative has been assigned to the project.
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 Electronic Files

Digital Computer Aided Design (CAD) files 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 in CAD or GIS format.  Maps should be identified as recorded, tentative or other, and be designed in coordinates using feet as horizontal and vertical units. The list of features below is what is needed at a minimum within the submitted files.
  • Building footprints with numbers and names
  • Driveways or easements indicating private property (if applicable)
  • Lot lines with lot numbers (if applicable)
  • Property line (public property and private property)
  • 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
  • Tie-points (minimum of 2 with bearings and distances to section corners/1/4 corners/etc. or to street intersection centerlines)
  • Title/Cover sheet
  • Vicinity map

A PDF export also needs to be provided for each plan and must contain the following in order to support the development of gas facility construction plans:
  • Bridge and bridge number (if applicable)
  • Highways (if applicable)
  • Land indicators (section lines, section corner, township/range lines, township/range indicators)
  • Minimum requirements listed above for CAD and GIS files
  • Parking lot (if applicable)
  • Sidewalk features (curbs, gutter, edge of pavement)
  • Substructures (electric, gas, oil, steam/air, telephone, TV/cable, water, reclaimed water, sewer, storm drain, catch basins)
  • Utility features (power poles, light poles, fire hydrants)
  • Walls/Fences (retaining, landscape, etc.)

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 (must include .shp, .dbf, .shx, and .prj)
    • Personal Geodatabase file (PGDB)

Non-Vector (Scanned) 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 scanned maps must contain the minimum requirements stated above, as well as a legend, symbology, and scale (English/metric). All necessary Landbase information pertaining to the scope of the project must be legible, must include all pages, and cannot be hand-drawn.
