History of Underground Program
1948 - Pilot program to install underground system in 78-home subdivision
1948-1967 - Underground construction at developer option
1968 - Council mandates that all new installations be underground
1969 - Fiberglass vault successfully tested

Current Status
Program completed in 2006
$1-2 million per year – roughly 2.9% of
total budget
Have converted 7,200 services at a cost
of $25, 425,161 (avg. $3,531 each)
Common Obstacles
Conflicts with other utilities Conflicts with other City Departments Phone lines still aerial Installation delays after design
complete
Lessons Learned
Conduit backbones no longer used Flowfill used with discretion No longer converted services “on
demand” Shorter time between design and
construction Dedicate staff member to design Coordination with other dept/utilities
What Worked?
Council Support Customer Support Funds Available Increased value to customers Increased reliability – no storm
related outages since 2007
