extenders, transformers, capacitor banks, aerial storage loops, splice enclosures, etc. All new facilities must be
placed underground. See section 9.2 of Chapter 46
and section 4 of Chapter 47 of Chandler City Code.
Aerial overhead in City ROW or PUE must be shown and called out on plans. If a riser is to be placed, identify
new connection or existing aerial plant being tied into and method of connection. Existing aerial fiber storage
and splice enclosures are considered embargoed and must be converted to underground. A one-time installation
of a riser stub cable may be permitted at the discretion of the City Engineer and should be sized appropriately
and spliced accordingly so that future access to aerial splice enclosures is not required. New risers are not
allowed on poles when high-voltage power lines (above twelve (12)kv) are present as required by
section 4 of
Chapter 47 of Chandler City Code.
Convert to first existing pole beyond property limits.
• Place underground all overhead utility lines, either within a proposed development or redevelopment project
within public ROW or easements adjacent to the project. Utility poles and lines are defined herein as the
poles, structures, wire, aerial cables and related facilities used in the distribution of electricity or in the
transmission of telecommunications, telegraph, data, radio or video communications. This requirement
includes both new and existing utility lines on and adjacent to the project, including lines which extend across
public streets, alleys or easements adjacent to the property being developed or redeveloped. Existing utility
lines adjacent to a project must be under-grounded up to the first existing pole beyond the limits of the
property. This requirement includes the undergrounding of all existing overhead service lines attached to the
lines to be removed along with necessary conduit, supports, restoration, etc., necessary to convert the service
line from overhead to underground. The requirement must apply regardless of the existence of easements
for overhead lines. When high-voltage lines (above twelve (12) KV or similar) are present, all lines other than
the high-voltage lines must be placed underground. See section 4 of Chapter 47 of Chandler City Code

associated utilities decline joint trench opportunities, submit written documentation to Utility Coordination via
