Steven Catanach, Light & Power Operations Manager
SUBJECT
First Reading of Ordinance No. 027, 2014, Approving Revisions to the Fort Collins Utilities' Electric
Construction Policies, Practices, and Procedures.
EXECUTIVE SUMMARY
The purpose of this item is to adopt the revised Electric Construction Policies, Practices, and Procedures
(ECPPP). The ECPPP provides definition to developers and contractors related to the construction of electrical
facilities.
STAFF RECOMMENDATION
Staff recommends adoption of the Ordinance on First Reading.
BACKGROUND / DISCUSSION
The ECPPP establishes rules for developers and contractors in the construction of electric facilities. The last
revision of these rules was approved in 2002 (Ordinance No. 083, 2002). This version did not include vital
metering requirements and standard construction drawings. The current additions to the rules document
current practices of the Light & Power utility; it is important to have these requirements formally included and
documented in the approved ECPPP document. Out-of-date references to industry codes and standards are
updated in the current revision. Confusing definitions of terms have also been reworded to clarify. These
modifications will help developers/contractors understand the City’s requirements as well as local electric
construction industry and our internal employees.
PUBLIC OUTREACH
Light & Power held a “feedback forum” for external stakeholders (i.e. electric construction contractors and
electricians) on November 18, 2013. Invitations were sent to approximately 266 individuals and businesses.
Additionally, the draft revisions were posted on the City Web site prior to the forum to allow stakeholders to
gain familiarity with the changes. There were no attendees at the forum nor any comments from the website.

City of Fort Collins Utilities
Electric Construction Policies, Practices and Procedures
1. Authority for Regulations
This policy, and the regulations it implements, are authorized by Section 26- 463 of the Code
of the City of Fort Collins, and shall be available for public review at the Fort Collins Utility
Service Center and the Office of the City Clerk of the City of Fort Collins.
2. Application of Policy
This policy applies to all construction, new development, redevelopment or remodeling.
3. Underground Construction Required
All electric utility lines and line extensions shall be underground in accordance with the
requirements of the "Electric Service Rules and Regulations." Permanent buildings or structures
shall not be located directly over underground electric utility facilities unless approved by
Utilities Executive Director.
4. Costs
4.1. New Development and Redevelopment
Cost estimates from preliminary plats will be furnished on request to developers for
planning purposes (based on average electric costs developed by the Fort Collins
Utilities (hereinafter called the Utilities) from previously completed projects).
Developers will receive a firm price for the underground electric system for a
subdivision, mobile home park or project development plan after providing the Utilities
with:
1. one copy of the final approved subdivision plat, and
2. the number, size and location of points-of-service at which electric service is
requested.
When the developer requests the actual construction of the project be started, a payment
of fifty percent of the quoted firm price will be required. This partial payment need only
be paid on the portion of the underground electric system which is to be constructed and
not necessarily on the whole subdivision project, provided that such portion is suitable
for partial electric service. Quoted firm prices will include off-site facilities, primaries
and streetlights. The owner will be charged for electric services not paid for by the
developer.
The underground electrical system will be installed in two phases:
1. Phase one includes the installation of the primary conduit, transformer vaults,
primary conductor and customer service provisions from the transformer vault to
the nearest lot corner or on-site transformer. Upon completion of this phase of
the project, the final payment of the quoted firm price becomes due and payable.
The electrical system will be energized following receipt of payment of all
project fees and charges.
2. Phase two includes the installation of the customer's service to the lot corner or
on-site transformer or meter socket. Service will be installed upon mutual
agreement, as to point of-service and meter location. A separate charge will be
made for the service prior to installation.
4
Modifications to the development plans requiring field changes in the electric system
and unforeseen construction obstacles such as frost and rocky soil conditions will be
charged on a change order basis and will be coordinated with the developer prior to
proceeding with the work.
4.2. Modifications to Capacity
For remodeling or other modifications where the customer's electric panel capacity is
increased and where development charges have not previously been paid, development
charges (off-site facilities, primary and streetlights) are applicable to the increased
capacity on a prorated basis. All charges for on-site costs are applicable per the Line
Extension Policy of the "Electric Service Rules and Regulations".
5. Residential Service Construction
This section of the policy applies to new subdivided areas where curb (except for radius
sections) and grading have been completed but where gas and telephone utilities and paving have
not been installed (see Section 9 - Construction Coordination Sequence).
Unless capacity demand is substantially higher than normal as determined by the Utilities
Executive Director or his or her designee, residential service construction must utilize a single
phase primary system complete with transformer vaults and transformers designed to convert the
primary system voltage to the standard residential voltage of 120/240 volts, three wire single-
phase, including the three wire electric service to the meter location. For detailed metering
equipment and location information, reference Section 8 – Metering. The electric facilities will
generally be installed underground behind the curb or sidewalk with a minimum cover of 30
inches, and will generally be completely at or below grade utilizing front lot line construction.
Streetlighting will be installed in accordance with the City of Fort Collins design criteria and
standards for streets.
.
