GENERAL PROJECT INFORMATION/LOCATION
Project description: A Site Specific Development Plan and Use by Special Review Permit for an accessory
buildings with gross floor area larger than four percent(4%)of the total lot area, as stated in Section 23-3-
30, per building on lots in an approved or recorded subdivision plat or lots part of a map or plan field prior
to adoption of any regulations controlling subdivisions in the A(Agricultural)Zone District
This project is south of CR 126 and is west of CR 19.
Parcel number 020127241005.
Access is from CR 19.
ACCESS
An Access Permit application was not submitted with the application materials. Public Works has reviewed
the submitted materials and provides a recommendation for access locations based on County code and
safety criteria in accordance with the Weld County Engineering and Construction Criteria. Shared use of
non-maintained public County ROW meets the code and spacing requirements. Questions concerning
access requirements can be directed to Public Works access permit division.
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 19 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.
TRACKING CONTROL POLICY
Per Chapter 12, Appendix 12A.10.1, traffic volumes to the proposed facility may require the installation of
a tracking control device and/or a minimum of four inches 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.
Less than 20 passenger vehicle round trips/day, no upfront tracking control requirements.
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:
A 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.
Detention pond waived and a simple drainage narrative:
A drainage narrative is required and full drainage report and detention pond waived if the site qualifies for
an exception to detention requirements listed below.
The drainage narrative must include at the minimum:
1. Description which exception is being applied for and supporting rationale
2. Where the water originates if it flows onto the property from an offsite source
3. Where it flows to as it leaves the property
4. The direction of flow across the property
5. If there have been previous drainage problems with the property
Exceptions.
1. Exceptions to stormwater detention shall not jeopardize the public health, safety, and
welfare of public and private property. Exceptions shall be supported with a drainage
narrative.
a. No stormwater detention will be required for sites that meet any of the following
conditions. Requirements of the Municipal Separate Storm Sewer System (MS4)
areas remain applicable.
1) Use by Right or Accessory Use in the A(Agricultural)Zone District.
MS4
This site is not in a defined Municipal Separate Storm Sewer System (MS4)area which is a more urbanized
area with state mandated, higher water quality requirements
CONDITIONS OF APPROVAL
A. The plan shall be amended to delineate the following:
1. County Road 19 is a gravel road and is designated on the Weld County Functional Classification
Map as a local road which requires 60 feet of right-of-way at full buildout. The applicant shall
delineate on the site plan the existing right-of-way. All setbacks shall be measured from the edge
of right-of-way. This road is maintained by Weld County. (Department of Public Works)
2. Show and label the approved access locations, approved access width and the appropriate turning
radii (25')on the site plan. The applicant must obtain an access permit in the approved location(s)
prior to construction. (Department of Public Works)
3. The applicant shall show the drainage flow arrows. (Department of Public Works)
DEVELOPMENT STANDARDS (NOTES ON THE SITE PLAN)
1. The property owner shall control noxious weeds on the site. (Department of Public Works)
2. The access on the site shall be maintained to mitigate any impacts to the public road including damages
and/or off-site tracking. (Department of Public Works)
3. Any work that may occupy and or encroach upon any County rights-of-way or easement shall acquire
an approved Right-of-Way Use Permit prior to commencement. (Department of Public Works)
4. Access will be along unmaintained County right-of-way and maintenance of the right-of-way will not be
the responsibility of Weld County. (Department of Public Works)
5. The historical flow patterns and runoff amounts on the site will be maintained. (Department of Public
Works)

map or plan field prior to adoption of any regulations controlling subdivisions in the A
(Agricultural) Zone District.
The application is requesting to allow 3 storage sheds that exceed the 4% lot coverage
requirement. The existing residence is served by an individual well (254064) and a
septic system permitted for three bedrooms (SP-0300476).
We recommend that the following requirements be incorporated into the permit as
development standards:
1. Any septic system located on the property must comply with all
provisions of the Weld County Code, pertaining to On-site Wastewater
Treatment Systems.
2. A permanent, adequate water supply shall be provided for drinking and
