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: A Site Specific Development Plan and Use by Special Review Permit for a mineral resource development including open pit mining (sands, gravels and stones), and materials processing including stockpiling, crushing and screening, recycling operations, and importing of raw and recycled materials as well as two mobile trailers in the A (Agricultural) Zone District. The applicant is proposing to mine a new gravel pit on parcel 047308000004. This project is NW of the intersection of CR 139 and CR 104.5. Access is from CR the corner of CR 139 and CR 104.5. Roads: County Road 139 and CR 104.5 are designated on the Weld County Road Classification Plan as a local road, which requires 60 feet of right-of-way at full build out. This project is not adjacent to either of these roadways; therefore, no additional requirements are necessary. There are no known traffic counts on the roads in this area. Discussions with PW Road Supervisor indicated that these roadways are graded only once a month, have very little traffic, sharp curves, and low water crossings that may be difficult to navigate at times. Additional truck traffic will likely impact these roadways and require additional maintenance. Traffic: The traffic information provided with the submittal states that the site will operate from dusk till dawn seven days per week with 6-8 employees on site. They anticipate mining the site in 2 phases with completion of both phases expected in approximately 2 yrs. Truck traffic will consist of 25-30 trucks per day. Traffic Narrative with Triggers: A Traffic Impact Study can be waived and a detailed Traffic Narrative submitted if the applicant agrees to traffic triggers. Any triggers based upon the traffic narrative or the traffic study will be included within the improvements and road maintenance agreement. The Traffic Narrative must include at the minimum: 1. The type (i.e. trucks/passenger vehicles etc...) and number of vehicles per day 2. Peak hour traffic numbers 3. Expected routes 4. Trip distribution along the routes (i.e. 50% of traffic will come from the north, 20% from the south, 30%from the east) 5. Specifically agree in writing to the below improvements triggers. A. 200 vpd or significant dust as identified by County-Mag-Chloride dust abatement B. 300 vpd alternative pavement C. 400 vpd pavement Access: An Access Permit is required for new accesses and/or change of use of an existing access, the fee and photos are required (Access permit instructions and application can be found at http://www.co.weld.co.us/Departments/PublicWorks/Permits/Applications.html.) Chapter 6, Sections 6.3, 6.4 and 6.5 of the Weld County Engineering and Construction Criteria, offer access design guidance. (This document can be found at http://www.co.weld.co.us/Departments/PublicWorks/EngineeringandRig htofW ay/Eng ineeringCriteriaand P olicies.html) Existing access points with change of use or new access points may or may not be granted. Questions pertaining to access permits or access design shall be directed to the Public Works Department. An access application has been submitted and is under review by PW. The application does not state how the applicant will get access to the parcel from the County road system. It appears the project will be accessing across the parcel to the east which is held by the same owners and will also be accessing across parcel (047315000008)owned by Two Mile Ranch. This would require an access easement from Two Mile Ranch in order to get access to the County Roads. Should at any time the applicant chooses to use the section line right of way for access, a non-exclusive license agreement would be required for this use. The applicant shall contact this department for further information on section line right of way use. The gate (if used) must be set back a minimum of 75 feet from future right-of-way to allow a truck to pull completely off of the roadway and open the gate after the future road widening. Tracking control is required to prevent tracking from the site onto the County Roadway. o Temporary Tracking Control shall be used during construction unless permanent tracking control is installed ahead of construction activities. o Standard tracking control for accesses onto gravel roads includes double cattle guards at the access point. Other PW Permits: A Right-of-Way Use Permit is required for any work in the Weld County Right-of-Way. Contact Weld County Public Works at 970-304-6496 ext. 3764. A Transport Permit is required for any oversize and/or over weight vehicles. Contact Weld County Public Works at 970-304-6496 ext. 3764.
