SUBJECT: USR18-0040 Alden Solar
The Weld County Department of Public Works 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
GENERAL PROJECT INFORMATION/LOCATION
Project description: A Site Specific Development Plan and Use by Special Review Permit for a Small Scale
Solar Facility (2MW) in the A (Agricultural) Zone District.
This project is south of CR 66 and is east of and adjacent to CR 51.
Parcel number 080129000046.
Access is from CR 51.
ACCESS
An Access Permit application was submitted with the application materials. Public Works has reviewed the
application and provides a recommendation for access locations based on County code and safety criteria
in accordance with the Weld County Engineering and Construction Criteria. The proposed new access point
does not meet the spacing criteria. Shared use of an existing access point to the north is recommended.
Questions concerning access requirements can be directed to Public Works access permit division.
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.
For new accesses and/or change of use of an existing access, the fee and photos are required (photo
looking left and right along roadway from the access point and looking in to and out of the access point).
These photos are used to evaluate the safety of the access location. Access permit instructions and
application can be found at https://www.weldgov.com/departments/public works/permits/. Chapter 6,
Sections 6.3, 6.4 and 6.5 of the Weld County Engineering and Construction Criteria offer access design
guidance, which can be accessed at: https://www.weldgov.com/departments/public works/engineering/.
Per Chapter 12, Appendix 12A.4.1 of the Weld County Code, an access approach that is gated shall be
designed so that the longest vehicle (including trailers) using the access can completely clear the traveled
way when the gate is closed. In no event, shall the distance from the gate to the edge of the traveled surface
be less than 35 feet.
For shared accesses, Public Works strongly recommends the property owner establish an access road
maintenance agreement so future owners of the properties will be aware of their requirements for shared
maintenance of the access road. This is not a requirement, but is recommended to avoid property owner
conflicts in the future.
ROADS AND RIGHTS -OF -WAY
County Road 51 is a paved road and is designated on the Weld County Functional Classification Map (Code
Ordinance 2017-01) as a(n) collector road, which requires 80 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.
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 51 counted 1039 vpd with 34% trucks.
The traffic information submitted with the application materials indicated that during site preparation,
equipment delivery, and construction, there will be a maximum of 24 daily roundtrips, including both
passenger vehicles and trucks. After construction is complete, there will be approximately 1 vehicle trip per
month.
TRACKING CONTROL POLICY
Tracking control will be required during construction of the site.
IMPROVEMENTS AND ROAD MAINTENANCE AGREEMENT
Public Works is requireing an Improvements Agreement during construction one or all the following
reasons:
• Off -Site Public Improvements
• Road Maintenance Agreement
• Construction Maintenance Agreement
• Access Improvements Agreement
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 waived and a simple drainage narrative:
The applicant has submitted a drainage narrative indicating that the site meets exception 23-12-30-F.1.a.14
for sites greater than 5 gross acres being allowed a one time exception for the addition of a 2000 square
foot building or equivalent imperviousness. The applicant is proposing the addition of the equivalent
imperviousness of a 1540 square foot building.
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.
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, 303-692-3575.

Re: USR18-0040 Alden Solar CSG LLC
Environmental Health Services has reviewed this proposal for a Site -Specific
Development Plan and Use by Special Review Permit for a small scale solar facility
(2MW) in the A (Agricultural) Zone District.
As no employees will be located at the site, permanent water and sewer is not required.
Portable toilets, hand washing units and bottled water can be utilized during
construction.
Environmental Health Services recommends that the following requirements are
incorporated into the permit as development standards:
1. All liquid and solid wastes (as defined in the Solid Wastes Disposal Sites and
Facilities Act, 30-20-100.5, C.R.S.) shall be stored and removed for final
disposal in a manner that protects against surface and groundwater
contamination.
2. No permanent disposal of wastes shall be permitted at this site. This is not
meant to include those wastes specifically excluded from the definition of a solid
waste in the Solid Wastes Disposal Sites and Facilities Act, 30-20-100.5, C.R.S.
3. Waste materials shall be handled, stored, and disposed in a manner that
controls fugitive dust, fugitive particulate emissions, blowing debris, and other
potential nuisance conditions. The facility shall operate in accordance with
Chapter 14, Article 1 of the Weld County Code.
4. Fugitive dust should attempt to be confined on the property. Uses on the
property should comply with the Colorado Air Quality Commission's air quality
regulations.
5. The operation shall comply with all applicable rules and regulations of State and
Federal agencies and the Weld County Code.
