EVERIST, INC. WHEREAS,the Board of County Commissioners of Weld County, Colorado, pursuant to Colorado statute and the Weld County Home Rule Charter, is vested with the authority of administering the affairs of Weld County, Colorado, and WHEREAS,the Board of County Commissioners held a public hearing on the 26th day of January, 2005, at the hour of 10:00 a.m. in the Chambers of the Board for the purpose of hearing the application of L.G. Everist, Inc.,7321 East 88th Avenue,Suite 200,Henderson,Colorado 80640, for a Site Specific Development Plan and Amended Use by Special Review Permit#1255 for Mineral Resource Development Facilities, including Open Pit Mining and Materials Processing, including a Concrete and Asphalt Batch Plant, in the A(Agricultural)Zone District on the following described real estate, to-wit: Lots 1, 2, 3, and 4, located in the N1/2 NW1/4, and Lot 6 located in the SW1/4 NE1/4 of Section 30, Township 2 North, Range 66;and Lot 3 located in the E1/2 NE1/4 of Section 25,Township 2 North, Range 67 West of the 6th P.M., Weld County, Colorado WHEREAS,said applicant was represented by Maureen Jacoby, Banks and Gesso, LLC, 720 Kipling Street, Suite 117, Lakewood, Colorado 80215, at said hearing, and WHEREAS, Section 23-2-230 of the Weld County Code provides standards for review of said Use by Special Review Permit, and WHEREAS,the Board of County Commissioners heard all of the testimony and statements of those present,studied the request of the applicant and the recommendations of the Weld County Planning Commission and all of the exhibits and evidence presented in this matter and,having been fully informed, finds that this request shall 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 Board of County Commissioners that the applicant has shown compliance with Section 23-2-230.B of the Weld County Code as follows: a. Section 23-2-230.b.1 --The proposed use is consistent with Chapter 22 and any other applicable code provisions or ordinances in effect. Section 22-5-80.A (CM.Goal 1) states, "Conserve lands which provide valuable natural mineral deposits for potential future use in accordance with state law." The amendment area contains a valuable sand and gravel 2005-0277 PL1396 AMENDED SPECIAL REVIEW PERMIT #1255 - L.G. EVERIST, INC. PAGE 2 deposit. Permitting of this site for this use will ensure that material is available to meet future needs. Further, Section 22-5-70.A states, "The County recognizes that mineral resource extraction is an essential industry. The availability and cost of materials, such as sand and gravel, have an economic affect on the general construction and highway construction industry." Further,the applicant states that the"County's annual growth rate over the last ten years averaged 3.6 percent,with total growth from 1993 to 2003 at 42.2 percent. Population estimates for Weld County predict an average of three percent growth for the next ten years." Section 22-5-80.B(CM.Goal 2)states,"Promote the reasonable and orderly development of mineral resources."The amendment proposes to mine the additional lands as existing mineral reserves are depleted. Section 22-5-80.C (CM Goal 3) states, "Minimize the impacts of surface mining activities on surrounding land uses, roads, and highways." The applicant states there will be no change in the permitted truck count or average production rate,and therefore no additional impacts on surrounding lands and roads, other than a change in the access location. The access location change will be accompanied by road improvements equal to the impact of such change between the Applicant and the Weld County Department of Public Works. The referral received from the Department of Public Works,dated October 10,2004,states,"The applicant shall enter into a new road maintenance and improvements agreement with the Weld County Department of Public Works for the additional safety improvements to the designated haul route associated with Weld County Road 18 and U.S. Highway 85." Further,the Department of Public Works states"...additional off-site safety improvements include: roadway alignment at both approaches to Bridge 18/25B,which is the small bridge crossing directly west of U.S. Highway 85, and a right turn lane(free right)onto the acceleration lane at U.S. Highway 85 to accommodate heavy hauling associated with the sand and gravel mining on the haul route." The applicant has submitted a traffic study by LSC Transportation Consultants, Inc.,dated May 2000. The traffic study indicates that the proposed expansion would generate the same amount of traffic, approximately 162 vehicles entering and 162 exiting,including 40 passenger vehicles and pick-up trips. The proposed amendment is to add additional acreage, and the applicant indicated no change in the number of vehicle trips. There will be no increase in truck traffic or average production (500,000 tons per year). Section 22-5-80.D (CM.Goal 4) states, "Minimize the impacts of surface mining activities on surrounding land uses, roads, and highways." The applicant states there will be no change in the number or type of processing equipment, or in the average production rate. The plant and processing 2005-0277 PL1396 AMENDED SPECIAL REVIEW PERMIT#1255 - L.G. EVERIST, INC. PAGE 3 areas will continue to be set back from County roads and will be partially screened through the use of earthen berms and vegetation. Section 22-5-80.F(CM.Goal 6)states,"The extraction of mineral resources should conserve the land and minimize the impact on surrounding land." The applicant states that final reclamation will begin within one year of completion of mining activities in any given phase,with seeding and planting completed during the appropriate time of year. The proposed reclaimed landform creates five lined water storage reservoirs,that will be of benefit to County citizens. Section 34-1-305,C.R.S.,addresses the preservation of commercial mineral deposits for extraction. The statute provides, in summary, that the Board shall not, by zoning, rezoning,granting a variance,or other official action or inaction, permit the use of any area known to contain a commercial mineral deposit in a manner which would interfere with the present or future extraction of such deposit by an extractor. This does not prohibit a board of county commissioners, a governing body of any city and county, city, or town, or any other governmental authority which has control over zoning from zoning or rezoning land to permit a certain use, if said use does not permit erection of permanent structures upon, or otherwise permanently preclude the extraction of commercial mineral deposits by an extractor from, land subject to said use. b. Section 23-2-230.6.2--The proposed use is consistent with the intent of the A (Agricultural) Zone District. Sections 23-3-40.A and 23-3-40.A.4 of the Weld County Code provide for Mineral Resource Development facilities; including open pit mining and materials processing;including a Concrete and Asphalt Batch Plant,as a Use by Special Review in the A(Agricultural)Zone District. c. Section 23-2-230.6.3--The uses which will be permitted will be compatible with the existing surrounding land uses. Surrounding land uses are residential and agricultural. There are existing buildings on the parcel, including several single family residences and outbuildings. Additionally, there are oil and gas wells, tanks, and appurtenances that will not be impacted by the mining activities. Existing single family dwellings that may be impacted by the proposed mining activities are to be relocated to other parcels of land outside of this mining application. d. Section 23-2-230.6.4--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. 2005-0277 PL1396 AMENDED SPECIAL REVIEW PERMIT#1255 - L.G. EVERIST, INC. PAGE 4 Existing land uses surrounding the property are typically agricultural and rural residential in use. Additionally, there are four County-permitted sand and gravel mines, in addition to the applicant's Fort Lupton Sand and Gravel facility located within two miles of the amendment area. Weld County has two facility's located to the north—Koenig and Bearson mines; and the Heit Mine and NCCI's Zadel Mine are located to the south. The proposed mining and reclamation plans for water storage have been designed to be compatible with the existing surrounding and approved future land uses. State Highway 85 is approximately 0.5 mile to the east. Little Dry Creek traverses the western edge of the amendment site,the Lupton Bottom Ditch bisects the amendment and existing mine site, and the South Platte River serves as the eastern property extent. The City of Fort Lupton is within the three-mile referral area and is approximately 0.5 miles to the south of the permit area. The amendment and existing site are outside of the Intergovernmental Agreement Area as evidenced by the Notice of Inquiry form submitted with this application. The City of Fort Lupton,in a letter dated October 6,2004,stated that the Fort Lupton Planning Commission was to review this case on October 12,2004, at 7:00 p.m. Staff received the October 12, 2004, Meeting Minutes which state "... we have reviewed the request and find no conflicts with our interest..." The Department of Planning Services believes that,with the endorsement of the Conditions of Approval contained in this recommendation,the approval of this use will not jeopardize the health,safety,or welfare of the surrounding property owners. e. Section 23-2-230.6.5--The application complies with Section 23-5-200 of the Weld County Code. The proposal is located within the Flood Hazard Overlay District area, as delineated on FIRM Community Panel Map #080266-0868C,dated September 28, 1982. The applicant will be required to amend its existing Flood Hazard Development Permit#355 to address the proposed uses associated with this amendment. f. Section 23-2-230.6.6--The applicant has demonstrated a diligent effort to conserve prime agricultural land in the locational decision for the proposed use. The parcel is designated as"Other"and "Irrigated Land (Not Prime)". No lands associated with this amendment are identified as "Prime" agricultural land. Much of the property is located within the 100 year floodplain,thus limiting the agricultural productiveness of the site. The area has historically been utilized as pastureland. g. Section 23-2-230.6.7 -- The Design Standards (Section 23-2-240, Weld County Code),Operation Standards(Section 23-2-250,Weld County Code), Conditions of Approval, and Development Standards ensure that there are 2005-0277 PL1396 AMENDED SPECIAL REVIEW PERMIT#1255 - L.G. EVERIST, INC. PAGE 5 adequate provisions for the protection of the health,safety,and welfare of the inhabitants of the neighborhood and County. h. Section 23-4-250 -- Additional requirements for Open-mining have been addressed through this application and the Development Standards will ensure compliance with Section 23-4-250 Weld County Code.
