COMMENTS
GENERAL PROJECT INFORMATION/LOCATION
Project description: Salt Water Injection Well Facility
This project is north of and adjacent to CR 132 and is west of and adjacent to CR 71.
Parcel number 020902000002.
Access is from CR 132.
ACCESS
Weld County Public Works has reviewed the application materials related to access. The applicant is
proposing accessing the site off of County Road 132, approximately 660 feet west of County Road 71. This
meets the safety spacing criteria.
Per Chapter 12, Article 5, Section 12-5-30, an Access Permit is required for access to Weld County
maintained roadways. We strongly encourage you to discuss your access with Public Works prior to laying
out your site plan to ensure the approved accesses are compatible with your layout. Per Chapter 12, Article
V, Section 12-5-30. F, when feasible, there shall be no net increase in the number of accesses to a public
road. Minimum access spacing widths are shown in Weld County Code Appendix Table 12A-2. Please refer
to Chapter 12 of the Weld County Code for more information regarding access.
ROADS AND RIGHTS -OF -WAY
County Road 132 is a gravel road and is designated on the Weld County Functional Classification Map
(Code Ordinance 2017-01) as a(n) local road, which requires 60 feet of right-of-way. The applicant shall
delineate on the site map or plat the future and existing right-of-way and the physical location of the road.
If the right-of-way cannot be verified it shall be dedicated. Pursuant to the definition of setback in the Weld
County Code, Chapter 23, Article III, Section 23-3-50, the required setback is measured from the future
right-of-way line. Be aware that physical roadways may not be centered in the right-of-way. This road is
maintained by Weld County.
County Road 71 is a gravel road and is designated on the Weld County Functional Classification Map (Code
Ordinance 2017-01) as a(n) local road, which requires 60 feet of right-of-way. The applicant shall delineate
on the site map or plat the future and existing right-of-way and the physical location of the road. If the right-
of-way cannot be verified it shall be dedicated. Pursuant to the definition of setback in the Weld County
Code, Chapter 23, Article III, Section 23-3-50, the required setback is measured from the future right-of-
way line. Be aware that physical roadways may not be centered in the right-of-way. This road is maintained
by Weld County.
Per Chapter 12, Article 4, Section 12-4-30.B, a Weld County Right -of -Way Use Permit is required for any
project that will be occupying, constructing or excavating facilities within, and/or encroaching upon, any
County rights -of -way or easement. Right -of -Way Use Permit instructions and application can be found at
https://www.weldgov.com/departments/publicworks/permits/.
Weld County will not replace overlapping easements located within existing right-of-way or pay to relocate
existing utilities within the County right-of-way.
TRAFFIC
Latest ADT on CR 132 counted 32 vpd with 42% trucks.
The traffic information submitted with the application materials indicated that there will be approximately 80
daily semi roundtrips and 10 daily passenger vehicle round trips.
TRACKING CONTROL POLICY
Per Chapter 12, Appendix 12A.10.1, traffic volumes to the proposed facility require the installation of a
tracking control device and a minimum of 300 feet of compacted recycled asphalt or aggregate road base.
Tracking control is required to prevent tracking from the site onto public roadways. Temporary Tracking
Control shall be used during construction unless permanent tracking control is installed ahead of
construction activities. Recycled concrete is not allowed in County right-of-way. Tracking control devices
can be double cattle guards or rip rap (6" washed rock). Tracking control for unmaintained public right-of-
way is required just prior to entering publicly maintained roadways. A variance request for alternatives to
the tracking control requirement can be submitted to Public Works for review and consideration.
IMPROVEMENTS AND ROAD MAINTENANCE AGREEMENT
Public Works is requiring an Improvements Agreement with triggers for auxiliary lanes and dust control.
The triggers for auxiliary lanes are:
• 10 VPH turning left into the facility triggers a left turn deceleration lane
• 25 VPH turning right into the facility triggers a right turn deceleration lane
• 50 VPH turning right out of the facility triggers a right turn acceleration lane
• Safety Hazards related to turning left out of the facility triggers a left turn acceleration lane
The triggers for dust control are:
• 200 VPD triggers magnesium chloride dust abatement
• 300 VPD triggers alternative pavement
• 400 VPD triggers pavement
The submitted traffic study indicates that the site will have 80 semi truck round trips per day and 10
passenger vehicle round trips per day. In addition to the existing 32 vehicles per day on County Road 132,
this triggers the requirement for magnesium chloride dust abatement.
An Improvements Agreement is required for sites with required off -site improvements per Chapter 12,
Article 5, Section 12-5-60. Collateral is required to ensure the improvements are completed, and
maintained.
Improvements/Road Maintenance Agreement: An example agreement is available at:
https://www.weldgov.com/UserFiles/Servers/Server 6/File/Departments/Public%20Works/DevelopmentR
eview/sprusr.pdf. It will detail the approved haul route(s), outline when off -site improvements will be
triggered, and include a maintenance agreement for the haul routes. Possible mitigations included in the
road maintenance agreement may include but are not limited to: dust control, specified haul routes, damage
repairs, and future improvement triggers.
DRAINAGE REQUIREMENTS
This area IS within a Non -Urbanizing Drainage Area: Non -Urbanizing Drainage Areas typically require
detention of runoff from the 1 -hour, 100 -year, storm falling on the developed site and release of the detained
water at the historic runoff rate of the 1 -hour, 10 -year storm falling on the undeveloped site for NON -
URBANIZING areas.
Detention Pond summarized in a Drainage Report: The applicant has submitted a preliminary drainage
report. A final drainage report and detention pond design shall be completed by a Colorado Licensed
Professional Engineer and adhere to the drainage related sections of the Weld County Code. The drainage
report must include a certification of compliance stamped and signed by the PE which can be found on the
engineering website. General drainage report checklist is available on the engineering website. More
complete checklists are available upon request.
GRADING PERMIT
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, Public Works 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 Public Works for more information.
