6. CR-600 (Piedra Road) is asphalt-paved, 2-lane, 26+feet wide with unpaved shoulders varying from 40 to 50 feet total width, with 12 feet S of the intersection and 10 feet N for the segment from MP 0.0 (SH-160) to MP 6.237 (beginning of FSR-630) 7. FSR-650 is 30-feet wide at the ROW line, with 35-foot radii on the N and at least 40-foot radii on the S, and the paved apron onto CR-600 is approximately 13 feet deep measured from the fog line, and with at least 190 feet clear sight distance at a grade of less than 1.5% (3 feet in 250 feet). Note that about 3-6 feet on both sides of the road have grass growing on the gravel surface, making the road appear narrower on aerial photos and to drivers, due to lack of traffic in the last 20+ years 8. Other than routine ranching operations and emergencies, the access road (FSR-650) will not be used to access other parcels of land from CR-600 9. Internal roads on the parcel may be realigned and rebuilt during mining operations 10. Coordination with Tim Hatch and his inspection indicate that the existing entrance of FSR- 650 onto CR-600 meets County Standards. 11. Recent improvements to the intersection of FSR-650 and CR-600: a. Realignment of the pre-existing 40-foot-wide gate to (1) be parallel to CR-600 and (2) 80 feet from the ROW. b. Removal of lower branches of the trees located on the SE corner of the intersection to at least 15 feet above the level of FSR-600 at 20 feet outside the fog line (through lane) of CR-600 to improve sight distance and establish a larger sight-triangle for exiting Discussion and Analysis: 1. ADT will be significantly less than 700, peak or average 2. There will be no interior access roads to subdivided lots 3. Secondary emergency access and muster areas for emergency shelter may be required by first responder agencies 4. No roads will be dedicated to public use on the parcel 5. Parking will be provided near the plant and stockpile area for up to 10 small vehicles and 20 multi-unit/single-unit trucks. 6. Scale and scalehouse will be located at the entrance to the plant and stockpile area from the access road. 7. Turn around points for emergency response equipment will be provided (minimum 108-foot diameter) at the plant and stockpile area and at the extreme limits of the mining area (on the pit floor) as mining progresses. 8. Drainage will be constructed to prevent channel flow along sides of access road and to retain stormwater on the plant and stockpile area while ensuring that roads are crowned and adequately drain to the shoulders to prevent problems with mud. See surface water management plan for additional information. 9. Access road will be maintained with minimum 4-inch Class 6 roadbase (3/4-minus) and less than 2%fines (for dust control).
