The locate service uses the following color codes to identify underground utilities:
Table 4 Color codes for locating utilities

Color Utility
White Proposed excavation area
Pink Temporary survey markings
Red Electric power lines, cables, conduit, and
lighting cables
Yellow Gas, oil, steam, petroleum, or gaseous
materials
Orange Communication, alarm or signal lines, cables,
or conduit
Blue Potable water
Purple Reclaimed water, irrigation, and slurry lines
Green Sewers and drain lines

NOTE: Use white paint to mark the area within which you want utility locations.
Once all utilities are located:
• Do not dig with machinery within 24 inches of the locate marks.
• Hand dig to expose all utilities to be crossed.

Coordinating utility trenching and construction
New construction typically involves the installation of telephone cables, cable television
cables, and natural gas lines; as well as electric power cables.
It is the responsibility of you and your builder to notify each utility about your intended
electric service installation as well as all other utilities providing service to your new
structure.

Transformer locations

PSE will install padmount transformers using the clearances listed in Table 5 and shown
in Figures 3 through 6.
Clearances between padmount transformers and structures must be measured from
the metal portion of the transformer closest to the building or structure (including any
overhangs).
