Case Summary:
The project is known as the Sweet Valley Pit (Mine) and will be operated by Central Colorado Water
Conservancy District ("CCWCD" or "Miner"). The Mine is an open -cut (truck and hydraulic excavator and/or
front-end loader) industrial sand and gravel mining and processing operation on land used historically for
agriculture. An estimated 650,000 tons of material will be mined per year for over just under twelve (12)
years in two (2) phases and will be reclaimed as two (2) lined water storage reservoirs.
The Mine is being permitted via the Colorado Division of Reclamation, Mining and Safety (DRMS)
Construction Materials Regular (112) Operation Reclamation Permit Application. The Miner has an
approved, but not perfected Colorado Division of Reclamation Mining Safety permit no. M-2024-015 for the
extraction of sand and gravel.
The Miner will employ two (2) aggregate processing plants with dry and wet screens, crushers,
electrical/control trailers with line power and/or generator power, conveyors, and stacking facilities at
various times during the mining activities as shown on the Extraction Plan map. All aggregate will be mined
with an excavator, dozer, and/or loader with the raw product being conveyed to the processing facility via
haul trucks and/or conveyors. A scale and scale operator trailer are located east of the Phase 2 south cell.
Overburden and aggregate stockpiles will be located as shown on the Extraction Plan map. The stockpiles
will have a height of ten (10) to thirty-five (35) feet. The aggregate mine operation will be conducted as a
dry pit with a slurry wall constructed around the mining operation.
There will be a maximum of sixty (60) employees on the site on any given day for the aggregate mining &
processing facilities. There will be approximately five (5) visitors per week on the site.
All traffic to and from the site will originate from HWY 60 and turn west on CR 40 then turn north on to a
leased roadway area on the Meining Cattle Company property until the site is reached along the south side
of the permit boundary. There will be one entrance to the aggregate processing facilities as shown on the
Extraction Plan map.
All commercial traffic exiting the site will travel east on CR 40 then turn south on HWY 60. Commercial
traffic entering the site will originate from HWY 60, travel west on CR 40 then turn north on to a leased
roadway area on the Meining Cattle Company property until the site is reached along the south side of the
permit boundary.
The Mine will normally operate during daylight hours, Monday through Saturday, for mining and processing,
but may need to operate at night for federal highway paving projects. Section 23-4-290.B of the Weld
County Code, allows the Board of County Commissioners to authorize additional hours of operation for
sand and gravel operations when the Board deems appropriate.
DEPARTMENT OF PLANNING SERVICES' STAFF RECOMMENDS THAT THIS REQUEST BE
APPROVED FOR THE FOLLOWING REASONS:
1. The submitted materials are in compliance with the application requirements of Section 23-2-260 of the
Weld County Code.
2. It is the opinion of the Department of Planning Services' staff that the applicant has shown compliance
with Section 23-2-220 of the Weld County Code as follows:
A. Section 23-2-220.A.1 - The proposed use is consistent with Chapter 22 and any other applicable
code provisions or ordinance in effect.
Section 22-2-60.B states, "Support responsible energy and mineral development."
USR25-0002 I Sweet Valley Pit
Page 2 of 13
Sweet Valley Pit (Mine) is a sand and gravel mine with a processing plant on approximately 147
acres. This mine will be operated by Central Colorado Water Conservancy District ("CCWCD" or
"Miner"). Weld County recognizes that mineral resource extraction is an essential industry and
supports the regional economy. The availability and reduced cost of local sand and gravel will
have a positively impact regional development and transportation construction costs and supply.
According to the Weld County Sand and Gravel Resources map dated July 1, 1975, the property
is classified as stream -terrace deposits with unevaluated aggregates. The DRMS application
submitted with the Weld County application shows that this area has been identified to contain
the desired materials (sand and gravel) and supports the orderly development of mineral
resources. Future development of these lands would be precluded until the mineral resource has
been extracted.
Section 22-2-60.B.1. states, `Ensure that surface development reasonably accommodates mineral
extraction.
The mine will not disturb any existing building. The property is crossed by approximately 2.62 acres
of the Western Mutual Ditch, which did not return a referral response. However, both the mining
and reclamation plans include adequate buffers from the ditch. A conveyor will carry aggregate
over the ditch adjacent to the existing bridge.
According to the Weld County Department of Oil and Gas Energy, there six (5) plugged and
abandoned wells and three gas pipelines, including LAP22-0011, running throughout the Permit
Area. The last well was plugged and abandoned last November, and only recently discoverable,
so the status wasn't reflected in the OGED referral. All pipelines and easements of record have
been incorporated satisfactorily into the plan.
Section 22-2-60.B.2. states, "Ensure that infrastructure, such as adequate roads and utilities,
exists or can be made available prior to development of energy and mineral resource production
facilities."
The haul route includes a private road (via an easement), County Road 40, Colorado Highway 60,
and U.S. Highway 85.
The Department of Planning Services — Development Review, in their referral dated February
26, 2025, is requiring the construction of a westbound right turn deceleration lane at the site's
access point on County Road 40. An Improvements and Road Maintenance Agreement is required
for the off -site improvements as a condition of approval to be accepted by the Board of County
Commissioners prior to recording the USR map.
The Colorado Department of Transportation has issued an access permit to the applicant. It
includes the requirement for improvements. Adherence to the conditions of the access permit is a
condition of approval.
B. Section 23-2-220.A.2 -- The proposed use is consistent with the intent of the A (Agricultural) Zone
District.
The use is consistent with the intent of the district in which the site is located. The site's property
parcels are zoned (A) Agricultural. The proposed project is a listed as an aggregate mine, permitted
in the (A) Agricultural Zone District as detailed in this Use by Special Review permit application,
and in the Weld County Code.
Weld County Code, Section 23-3-10, states in part "The A (Agricultural) Zone District is intended
to provide areas for the conduct of agricultural activities and activities related to agriculture and
agricultural production, and for areas for natural resource extraction and energy development,
without the interference of other, incompatible land uses." Chapter 23, Article III, Division 1, Section
23-3-40.R allows for open mining (sand, gravel, stone) and processing of minerals, subject to the
USR25-0002 I Sweet Valley Pit
Page 3 of 13
additional requirements of Article IV, Division 4, of the Weld County Code through a use by special
review outside of subdivisions and historic townsites.
C. Section 23-2-220.A.3 -- The uses which will be permitted will be compatible with the existing
surrounding land uses.
The adjacent lands are zoned A (Agricultural) and consist of farmland, rural residences, oil and gas
activity, and a former rural residence that will be turned into the CCWCD offices and associated
outbuildings.
There are eight (8) Use by Special Review (USR) permits within one (1) mile of the property
boundary: USR22-0030 (gravel pit — open mining), USR21-0004 (solar facility), USR14-0024,
USR13-0042 (mineral resource development facility - mining), USR-866 (oil and gas support
facility), MUSR16-0002 (mineral resource development facility - mining), USR13-0039 (automobile
repair), and USR-839 (commercial greenhouse).
The Weld County Department of Planning Services sent notice to twenty-one (21) Surrounding
Property Owners. One letter of objection and no telephone calls of inquiry were received regarding
the application. The letter included a request for limits be placed on the mining activities, such as
limiting hours and days of operation, noise and trucks per hour. A landscape plan is requested to
screen mining activity, manage weeds, and mitigate any negative effect on property values.
Weld County Code Design and Operations Standards attempt to mitigate the impact of mining on
surrounding properties. Sections 23-4-290.C and D address the removal of weeds, the requirement
for preserving a neat appearance, the protection of trees and ground cover along public road
frontages and drainage ways for the depth of the setback to protect against noise, dust, and
erosion. The site plan shows the use of stockpiles and a berm for noise mitigation for the residence
closest to the equipment, which has been placed as far away as possible.
The Weld County Code, Chapter 14, Article IX sets limits for noise levels in Weld County. The
daytime limit (daytime defined as 7:00 a.m. to 9:00 p.m.) for Industrial and Construction Activities
is 80 dBA during daytime hours. The daytime noise level limit from any property transmitted to
Residential, Commercial, and Nonspecified areas is 55 dBA. Noise levels must comply with the
limits set for the industrial zone district, with measurements taken 25 feet from the property line.
A noise modeling report from Wave Engineering submitted with the application concludes: "As
currently designed, the worst case predicted sound levels meet the Weld County Industrial limit at
the property boundary. The Residential and Commercial limit is not met at some points on the
property boundary but is met at all homes and commercial properties nearby. As the pit is
developed and the mining equipment moves below the surface, the sound levels will reduce further
below the limit." Compliance with the noise control plan is required as part of the development
standards.
CCWCD will provide dust abatement through its mining contractor. A water truck will be used to
treat the on -site areas (haul roads, aggregate processing area, etc.) to suppress dust. A water truck
and/or sprinklers will be used to control dust in circulation areas and material handling/stockpile
areas. Daily, prior to starting up plant operations all haul roads, processing area, circulation areas,
and stockpiles will be inspected to determine if wetting the surfaces are needed. Areas that cannot
be reached with the water truck will be wetted using sprinklers. If at any time during the day the
mining operations begin to generate dust that is leaving the site, CCWCD's contractor will have a
water truck on stand-by such that an area can be wetted immediately. An Air Emission Permit
(APEN) from the State is required to cover dust control for mining operations, haul roads, and all
processing equipment.
There will be a one -thousand -gallon fuel storage tank at the staging area for the processing plants
and it will include secondary containment. Mobile fueling/lubrication will typically be used to fuel
equipment. A Spill Prevention, Control, and Countermeasure Plan will be available on -site.

The applicant is requesting that the Weld County Board of County Commissioners extend the hours
of operation of the in -pit mining, storage, sales, and processing plant facility beyond daylight hours
to 24/7 operations for cities, counties, or CDOT, for night projects. Section 23-4-290.B of the Weld
County Code, allows the Board of County Commissioners to authorize additional hours of operation
for sand and gravel operations when the Board deems appropriate.
D. Section 23-2-220.A.4 - The uses which will be permitted will be compatible with future development
of the surrounding area as permitted by the existing zoning and with the future development as
projected by Chapter 22 of the Weld County Code and any other applicable code provisions or
ordinances in effect, or the adopted Master Plans of affected municipalities.
The site is located within a Weld County Opportunity Zone, according to the Weld County
Comprehensive Plan, which indicates the potential for future industrial or commercial uses, which
are compatible with mining. The site is classified as Urban-NonUrban Mix on the Comprehensive
Plan Map, which indicates urban development is near, but still at least one (1) mile away. In this
case, the urban -scale portion of the town of Gilcrest is exactly one (1) mile away.
The site is located within the three (3) mile referral area and the Coordinated Planning Agreement
Area (CPA) for the Towns of Platteville, Milliken, and Gilcrest. As part of the pre -application
process, the municipalities were sent a Notice of Inquiry (NOI) on November 13, 2023.
All three municipalities returned Notice of Inquiry forms stating no desire to annex, the Town of
Platteville, November 13, 2023, the Town of Milliken, February 21, 2024, and the Town of Gilcrest,
January 17, 2025. The property is located outside the Urban Growth Area of both the Towns of
Milliken and Platteville.
The property is located within the Town of Gilcrest Growth Priority Tier 3, according to the 2017
Gilcrest Comprehensive Plan Update. "Tier 3 contains all remaining lands within the Planning Area
that would require significant capital investments to provide public services. This tier offers
opportunities for additional IGA's with the surrounding municipalities and Weld County to help
ensure the Town has input regarding any potential development applications in this tier." And
according to the 2012 Framework Plan included in the 2017 plat, the property is designated for
"Agriculture / Large Lot" development, contains a regional commercial node on the northwest
corner, outside of the proposed mining extent.
The Towns of Gilcrest and Platteville submitted a joint letter on December 11, 2023, in accordance
with their Platteville-Gilcrest Coordination Agreement (2011). The letter stated concerns regarding
potential negative impacts to the South Platte River Corridor wildlife habitats, the danger if ground
water levels are raised, loss of developable land, and other impacts, such as traffic noise, air quality,
and aesthetics.
The applicant submitted with the application minutes from a December 9, 2024, meeting of the
Board of Trustees in which the Board indicated a desire for an Intergovernmental Agreement with
CCWCD, but decided not to take action.
E. Section 23-2-220.A.5 - The application complies with Chapter 23, Articles V and XI, of the Weld
County Code.
The property is not located within any overlay district officially adopted by the County, including A-
P (Airport) Overlay District, 1-25 Overlay District, Geologic Hazard Overlay District, MS4 - Municipal
Separate Storm Sewer System area, Special Flood Hazard Area, Historic Townsites Overlay
District, or Agricultural Heritage Overlay District.
Building Permits issued on the lot will be required to adhere to the fee structure of the County -Wide
Road Impact Fee Program, County Facility Fee and Drainage Impact Fee Programs.
F. Section 23-2-220.A.6 - If the use is proposed to be located in the A (Agricultural) Zone District, the
applicant has demonstrated a diligent effort has been made to conserve Prime Farmland in the
locational decision for the proposed use.
USR25-0002 I Sweet Valley Pit
Page 5 of 13
According to the U.S. Department of Agriculture Natural Resources Conservation Service Soil Map
submitted with the application, the soils, Olney fine sandy loam, Ascalon loam, and a small area of
Altvan loam, are considered "Prime Farmland, if irrigated," with much of the Mine on soils
designated as "prime" if both irrigated and reclaimed of excess salts and sodium. The subject
property is not irrigated at this time.
The Weld County Comprehensive Plan also protects these lands from uses interfering with
extraction of sand and gravel. Mineral extraction will provide economic revenues for Weld County
from the land and will not interfere with the agricultural productivity of surrounding properties.
Colorado Revised Statutes provides for the extraction of mineable resources prior to and surface
development.
G. Section 23-2-220.A.7 - There is adequate provisions for the protection of the health, safety, and
welfare of the inhabitants of the neighborhood and County.
The Design Standards (Section 23-2-240, Weld County Code), Operation Standards (Section 23-
2-250, and 23-4-290, Weld County Code), Conditions of Approval and Development Standards,
when combined with the provisions of the approved Division of Reclamation, Mining and Safety
permit can ensure that there are adequate provisions for the protection of health, safety, and
welfare of the inhabitants of the neighborhood and County.
This proposal has been reviewed by the appropriate referral agencies and it has been determined
that the attached conditions of approval and development standards ensure that there are
adequate provisions for the protection of the health, safety and welfare of the inhabitants of the
neighborhood and county and will address and mitigate impacts on the surrounding area with the
operation of open mining (sand, gravel, stone, and overburden) and processing of minerals.
This recommendation is based, in part, upon a review of the application materials submitted by the
applicant, other relevant information regarding the request, and responses from referral entities.
The Department of Planning Services' staff recommendation for approval is conditional upon the following:

On parcel(s) of land described as:
LOT A REC EXEMPT RE -3144; and part of the NE4, both in Section 30, T4N, R66W of the 6th P.M.,
Weld County, Colorado.
Dear Applicants:
I have scheduled a meeting with the Weld County Planning Commission on May 6, 2025 at 1:30 p.m.
A subsequent hearing with the Board of County Commissioners will be held on May 21, 2025 at 10:00
a.m. Both hearings will be held in the Hearing Room, Weld County Administration Building, 1150 O
Street, Greeley, Colorado. The property owner and/or authorized agent must be in attendance to
answer any questions the Planning Commission members or Board of County Commissioners may
have.
Colorado Revised Statute, C.R.S.24-65.5-103 (adopted as part of H.B.01-1088) requires notification of
all mineral estate owners 30 days prior to any public hearing. The applicant needs to provide the
Weld County Planning Department with written certification indicating the above requirement has
been met.
A representative from the Department of Planning Services will be out to the property a minimum of
ten days prior to the hearing to post a sign, adjacent to and visible from a publicly maintained road
right-of-way which identifies the hearing time, date, and location. In the event the property is not
adjacent to a publicly maintained road right-of-way, one sign will be posted in the most prominent
place on the property and a second sign posted at the point at which the driveway (access drive)
intersects a publicly maintained road right-of-way.
The Department of Planning Services' staff will make a recommendation concerning this application
to the Weld County Planning Commission and will be included in the staff report one week prior to
the scheduled Planning Commission hearing. You may view the staff report at https://aca-
