7-Day Completeness Review Comments:
The application is not complete, the following items need to be addressed.
DRAINAGE REQUIREMENTS:
The Pre-Application meeting minutes have expired. The minutes are valid for one year after the pre-
application meeting. The drainage requirements have changed since the pre-application meeting. The
following are the current drainage requirements for Weld County. Several exceptions to detention pond
requirements that may or may not be applicable to the site are highlighted below. Please contact
Department of Planning Services/Development Review Engineering for questions or assistance 970-353-
6100.
The drainage code is currently going through changes with the Board of County Commissioners.As of July
13th the draft code is to be used in a pilot program mode until August 17th when finalized.
The draft drainage code is available on the planning-engineering website.
http://www.co.weld.co.us/Departments/Plann ingZon ing/Eng ineering.htm I .
Detention Pond summarized in a Drainage Report may be required if the project does not fall under an
exception to stormwater detention requirements. Requirements for detention pond and requirements if the
detention pond is waived are below:
Detention pond requirements:
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 if project meets exceptions in code reproduced
below in section 23-12-30:
If the site qualifies for an exception to detention requirements listed below, a drainage narrative would be
required and full drainage report and detention pond may be waived.
The drainage narrative must include at the minimum:
1. Description which exception is being applied for and include supporting documentation.
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
DRAINAGE CODE REQUIREMENTS:
Section 23-12-30. Drainage Policy.
F. Exceptions to stormwater detention shall not jeopardize the public health, safety, and
welfare of public and private property.
Exceptions.
1. No stormwater detention will be required for sites that meet any of the following
conditions:
A. Use by right or accessory use in the A(agricultural)Zone District.
B. Zoning permits in the A (agricultural)Zone District.
C. A second dwelling permit in the A (agricultural)Zone District.
D. Towers including, but not limited to, cell, wind, and telecommunication towers.
E. Pipelines or transmission lines.
F. Gravel pits if the stormwater drains into the gravel pit.
G. Residential developments where all the following conditions exist:
1. Nine (9) lots or fewer.
2. The average lot size is equal to, or greater than, three (3)acres per lot.
3. Downstream roadway criteria are not exceeded.
4. The total post-development imperviousness for the rural residential
development does not exceed ten percent (10%), assuming that all internal
roads and driveways are paved, or will eventually be paved.
H. Development of sites where the change of use does not increase the
imperviousness of the site.
I. Urbanizing areas where the total project stormwater runoff of less than, or
equal to, 5 cubic feet per second (cfs)for the 1-hour, 100-year, storm event.
J. Non-urbanizing areas where the total project stormwater runoff of less than, or
equal to, 10 cfs for the 1-hour, 100-year, storm event.
K. Parcels with total area less than, or equal to, a 1.0 gross acre.
L. Individual parcel with an unobstructed flow path and no other parcel(s)
between the Federal Emergency Management Administration (FEMA)
regulatory floodplain channel and the project.
M. A parcel greater than 1 gross acre and less than, or equal to, 5 gross acres in
size is allowed a onetime exception for a 1,000 sq ft building or equivalent
imperviousness.
N. A parcel greater than 5 gross acres in size is allowed a onetime exception for a
2,000 sq ft building or equivalent imperviousness.
O. Approved by a variance (DRAFT Weld County Code Section 23-12-150)
Section 23-12-150. Stormwater Drainage Criteria Variances.
The following variance procedures are intended to allow additional exceptions to the code explicitly
listed in Section 23-12-30 provided certain requirements are met. Subsection A below is intended to
be a lower cost option which allows anyone to apply for a variance with or without stamped
engineering documentation. Subsection B below is intended to be used when more detailed
analysis and engineering support is required.
A. An applicant may request a variance for their site when conditions do not meet the drainage
exemptions described previously and impacts to the site and offsite properties are
insignificant. Requests will be reviewed by the Planning Director or his/her designee. No
variance will be considered if it may jeopardize the public health, safety, welfare and public
and private property. In order to be granted, the variance request must:
1. Demonstrate that granting of the variance will still adequately protect public health,
safety, and general welfare.
2. Demonstrate there are no adverse impacts, from stormwater runoff, to the public
rights of way and/or offsite properties as a result of the project.
Any engineer's supporting documentation or analysis has to be signed and stamped by a
licensed PE in the state of Colorado.
If the applicant's variance request is denied for not satisfying the above criteria and in the
sole discretion of the planning director or his or her designee, the applicant has the option
to follow the variance request in Subsection B below or appeal the denial to the Board of
Adjustment.
B. The applicant's engineer may request a variance. The variance request shall be stamped
and signed by a professional civil engineer licensed to practice in the State of Colorado.
Requests will be reviewed by the Planning Director or his/her designee. In order to be
granted, the variance request must:
1. Describe the design criteria of the Weld County Code of which a variance is being
requested.
2. Describe the proposed alternative with engineering rationale which supports the intent
of the Weld County Code.
3. Meet the design intent of the Weld County Code.
4. Demonstrate that granting of the variance will still adequately protect public health,
safety, and general welfare.
5. Demonstrate there are no adverse impacts, from stormwater runoff, to the public
rights of way and/or offsite properties as a result of the project.
An applicant can appeal to the Board of Adjustments the Director of Planning Services
decision regarding the variance per Article VI of this chapter.
C. Variance requests, if accepted, are not precedent setting and are based upon specific site
constraints.
Historic Flows:
The applicants will be required to maintain the historic drainage flows and run-off amounts that exist from
the property.
SITE MAP REQUIREMENTS
A Site Plan will be required identifying the following:
o Access Points,Turning Radiuses Required (25ft for passenger vehicles/60ft for trucks)or alternate
approved by CDOT.
o Drainage related features, detention pond, ditches, etc... if required above.
The above notes are provided as a courtesy to the applicant. While we strive to help identify as many
potential issues upfront during the pre application meeting we cannot anticipate every issue that may come
up during the formal application process. The information contained herein has been placed on file with the
Department of Planning Services. The pre-application is valid for a period of one (1)year from the date of
pre-application. If a formal application is not received following the time period specified herein the Planning
Department reserves the right to require a new pre-application meeting. Please note that all land use,
building and impact fees are subject to change throughout this time period.
