SUBJECT: USR15-0049 Tri-State transmission line and 3 substations
The Weld County Department of Planning Services-Engineering has reviewed this proposal. Staff
comments made during this phase of the application process may not be all-inclusive, as other issues may
arise during the remaining application process.
COMMENTS:
This project is a power transmission line project with three substations between CR14 north to CR50
between CR31 east to CR51.
Roads:
From the application materials it appears the transmission line crosses the following rights of way.

Traffic:
The application indicates there will be 55 workers during construction accessing the project alignment.
Vehicles vary from pickup trucks to tractor trailers. After construction the project would generate infrequent
trips to the transmission line and substations during operation. The line would be inspected annually and
occasionally for maintenance.
Access:
An Access Permit is required. For new accesses and/or change of use of an existing access, the fee and
photos are required (Access permit instructions and application can be found at
http://www.co.weld.co.us/Departments/PublicWorks/Permits/Applications.html.) Chapter 6, Sections 6.3,
6.4 and 6.5 of the Weld County Engineering and Construction Criteria, offer access design guidance. (This
document can be found at
http://www.co.weld.co.us/Departments/Pu blicW orks/Engi neeringand RightofW ay/EngineeringCriteriaand P
olicies.html) Existing access points with change of use or new access points may or may not be granted.
Questions pertaining to access permits or access design shall be directed to the Public Works Department.
TRACKING CONTROL:
Tracking control is required to prevent tracking from the site onto public roadways. Minimal standards are
listed below. Temporary Tracking Control shall be used during construction unless permanent tracking
control is installed ahead of construction activities.
For the substations it is anticipated there will be minimal traffic once construction is complete with Less
than 20 passenger vehicle round trips/day therefore no permanent tracking control requirements however
a gravel surface is recommended.
During construction a vehicle tracking pad will be required at all crossings to keep from tracking mud or
debris on to publically maintained roads.
A development standard will be included on the recorded site plan. "The site shall be maintained to
mitigate any impacts to the public road including damages and/or offsite tracking."
Improvements and Road Maintenance Agreement:
No improvements agreement will be required as the anticipated traffic is less than 21 round truck trips/day
or 50 round passenger vehicle trips/day. A development standard will be applied to the recorded plan
indicating any impacts to the road must be mitigated by the owner. There shall be no tracking from the site
onto publically maintained roads. The applicant is responsible for mitigation of any damage or offsite
tracking and upgrading and/or maintaining onsite tracking control.
Drainage Requirements:
The application materials indicated the stormwater runoff from the substations will be collected by detention
facilities. A drainage report and certification of compliance was supplied for the Colfer and Milton sites. A
draft drainage report was submitted for the Rattle Snake Ridge site as Public Works and the applicant
finalize this area with regards to CR49 widening.
The transmission line project does not require a detention pond design or water quality
treatment as it falls under an exception to stormwater detention in the new drainage code.
Grading Permit
For the substations, a Weld County Grading Permit will be required if disturbing more than 1 acre. Grading
Permit applications are accepted after the planning process is complete (plan recorded). An Early Release
Request Form may be entertained only after the applicant and Planning Department have reviewed the
referral and surrounding property owner comments.The Early Release Request may or may not be granted
depending on referral comments and surrounding property owner concerns. Contact an Engineering
representative from the Planning Department for more information.
A Construction Stormwater Permit is also required with the State for disturbing more than 1 acre. Contact:
Colorado Department of Public Health and Environment,Water Quality Control Division, Rik Gay, 303-692-
3575.
A grading permit is not required for transmission lines. Unless more than 1 acre is disturbed for construction
of non-transmission line items such as structures, parking lots, laydown yards etc...,a Weld County grading
permit will be required prior to the start of construction. Contact the Planning Department for more
information.
Geologic Hazard Area:
This area IS NOT in a Geologic Hazard Area.
Floodplain:
This project crosses a portion of the Box Elder Creek floodplain. A flood hazard development permit is
required for any development in the floodplain. Contact the floodplain planner Diana Aungst at 970-353-
6100.
Permits:
Contact the Permitting/Inspection agent for Weld County Public Works, at (970) 304-6496, ext. 3764 for a
Right-of-Way permit for any work that may be required in the right-of-way. A special transport permit will be
required for any oversized or overweight vehicles that may access the site and may also be obtained
through the same office.
