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 Digital Data Files

A Geographic Information System (GIS) data file is preferred. A Digital Computer Aided Design (CAD) file is also acceptable.  Either file format must have an organized identifiable and isolatable layer structure in a single file with all the required layers included.

Plans (property 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 file.
  • 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 (property map)  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 GIS and CAD file
  • 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 GIS and CAD File Formats (listed in order of preference):

  • GIS
    • Shapefile (must include .shp, .dbf, .shx, and .prj)
    • Personal Geodatabase file (PGDB)
    • File Geodatabase (GDB)
  • CAD
    • AutoCAD (.dwg) Version 2018 or lower
    • MicroStation (.dgn) version J or lower
    • Universal format (.dxf)

    Non-Vector (Scanned) Submittals

    Scanned copies of plans (property maps) are not encouraged but may be submitted for smaller-sized developments where a digital GIS or CAD file was not created and only copies of pre-existing plans (property 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.

    Required Plans and Documents for Each Project Type

    The plans and documents listed below are considered a baseline and additional plans and documents may be requested by the planning representative based on the individual requirements of the project.
    Please keep in mind that all project types listed below also require accurately identifying and providing the connected load, in BTUs and by equipment type or end-use. Manufacturer labels can assist with providing the actual connected load to the planning representative. 

    Additionally, a completed authorization form must be provided for third-party agents who will be obtaining confidential customer information and act on the customer/owner’s behalf:

    1Improvement plans include, but are not limited to: street improvement, water, sewer, storm drain, electric, cable, telephone, precise grading plan.
    *City-approved address list can be provided after you receive your contract from SoCalGas; however, it is needed prior to SoCalGas scheduling your project for construction.
