This memorandum summarizes the proposed site, its transportation-related impacts, and proposed improvements to accommodate future traffic. Site Description The proposed landfill site is located on the north side of Route 60 in eastern Cumberland County. Access to the landfill will be served by one proposed access on Route 60 (Anderson Highway) approximately 1,620 feet east of Route 606 (Blenheim Road). This site access is located approximately 1,070 feet west of the Powhatan / Cumberland County border. Existing Routes 654 and 685 currently run through the site and provide access to several homes located near the site. These routes will not be used by landfill operations. A section of these routes is proposed to be relocated in order to provide area for the southern cell of the landfill. This is conceptually shown in the site exhibit which follows. Trip Generation Table 1 on the following page summarizes the trip generation potential for this site. The components of site traffic are discussed below: Regional Waste Hauling: The hauling of regional waste by large semi-trailer type trucks will be mostly during the nighttime hours: 80% is expected to occur after 6 pm and before 6 am. The remaining 20% will occur during daytime hours (6 am to 6 pm). The projected daily tonnage to be delivered to the site is 3,000 to 5,000 tons. Based on an approximate truck capacity of 20 tons per truck, this represents a maximum of 250 truckloads. Approximately 80% of truckloads will come from the east on Route 60, and 20% from the west on Route 60. Leachate Hauling: Up to 31 trucks hauling leachate (6,000 to 8,000 gallon tanker trucks) per day may travel to and from the site. Again, 80% are estimated to come from the east on Route 60, and 20% from the west on Route 60. Trucks may arrive during both daytime and nighttime hours. Local residents: Cumberland County residents will be able to drop off trash at a designated station on the site. Currently, there are three other convenience centers in the County (Madison, ---PAGE BREAK--- Home Office Richmond Office: Serving the Southeast since 2002 John Davenport Engineering, Incorporated John Davenport Engineering, Incorporated 119 Brookstown Ave. Suite PH1 16003 Continental Boulevard Winston-Salem, NC 27101 South Chesterfield, VA 23834 Main: [PHONE REDACTED]; Fax: [PHONE REDACTED] Main: [PHONE REDACTED] Randolph, and Hamilton Convenience Centers); however, it is understood that the City will be closing at least one of the existing Convenience Centers. The available information indicates approximately four residents per hour may use the facility on weekdays, and a maximum of 30 vehicles per hour on Saturdays. 10 residents per hour on weekdays was assumed, to give more conservative results. Local garbage trucks: Up to 15 local garbage trucks per day may use the site during daytime hours. Employees, construction workers, and vendors: Approximately 15 employees may be on site during the daytime hours. Also, construction will occur periodically on site in order to prepare new sub-cells. This will occur approximately every other year, with potentially 15 construction workers on site. During the nighttime hours, approximately five employees may be on site. Finally, up to three vendors per day to the site may be expected. The resulting trip generation numbers are shown in Table 1 below. These numbers reflect a conservative estimate of peak hour trips in order to give a worst-case scenario.

This count indicated an annual average daily traffic (AADT) volume of 5,657 vehicles. Through volumes were projected at 2% growth per year from the current year 2018, using a ten- year projection for analysis purposes. This growth rate was based on a ten-year review of historical volumes on Route 60 both west and east of the Cumberland / Powhatan County line. The one with the higher growth rate (east of the County line) was selected, yielding a 2% annual growth rate. Left and right turn volumes were computed based on the trip generation numbers shown in Table 1 above and based on expected trip distribution patterns associated with each component of site traffic. The resulting turning movement volumes during AM and PM peak hours are shown in Table 2 below. Table 2 - Projected Volumes: Intersection of Route 60 and Proposed Access AM Peak Hour PM Peak Hour 2018 Existing 2028 Future Build 2018 Existing 2028 Future Build EB Left 0 18 0 25 EB Through 367 447 146 178 WB Through 78 95 334 407 WB Right 0 20 0 45 SB Left 0 9 0 57 SB Right 0 6 0 32 The need for left and right turn lanes at the proposed access on Route 60 was reviewed based on criteria in Appendix F of the VDOT Road Design Manual. Based on these projected volumes, the proposed access will warrant a right turn taper on Route 60. Volumes are below the threshold for the warranting of a left turn lane; however, a left turn lane is warranted based on high truck volumes and safety considerations. The attached turn lane exhibit proposes a full left turn lane with 200 feet of storage and 200 feet of taper, and a full right turn lane with 200 feet of storage and 200 feet of taper. These turn lanes are expected to enhance traffic flow and safety at this access. Access Management According to Appendix F of the VDOT Road Design Manual, for a route such as Route 60, which is a principal arterial with a speed limit of 50 mph or greater, the minimum spacing standard between a full access entrance and other full accesses or unsignalized intersections is 750 feet. The proposed access is located approximately 1,150 feet west from Pine Cove Trail, and approximately 1,620 feet east from Route 606 (Blenheim Road). Therefore, this access satisfies VDOT spacing requirements. Sight Distance The adequacy of sight distance at the proposed access was reviewed based on criteria in the VDOT Road Design Manual Appendix F. For Route 60 with a speed limit of 55 mph and a design speed of 60 mph (speed limit plus 5 mph), the required intersection sight distance is 710 feet looking left and 750 feet looking right (from the stop-controlled approach). Based upon preliminary information that will be field-confirmed for the construction plans submittal, the available sight ---PAGE BREAK--- Home Office Richmond Office: Serving the Southeast since 2002 John Davenport Engineering, Incorporated John Davenport Engineering, Incorporated 119 Brookstown Ave. Suite PH1 16003 Continental Boulevard Winston-Salem, NC 27101 South Chesterfield, VA 23834 Main: [PHONE REDACTED]; Fax: [PHONE REDACTED] Main: [PHONE REDACTED] distance is approximately 2,000 feet looking left and 2,000 feet looking right. Therefore, sight distance requirements are satisfied. Lighting Further review during the development of construction drawings should consider whether streetlights should be installed along Route 60 at this location, given the available sight distances on both the EB and WB approaches (approximately 2,000 feet) and the surrounding roadside environment. Route Relocations The site exhibit shows the approximate proposed relocation of a section of Route 654 (Pinegrove Road) and Route 685 (Miller Lane) internal to the site, in order to provide area for the southern cell of the proposed landfill. According to VDOT traffic counts taken in 2014, Route 654 has a volume of approximately 360 vehicles per day south of Route 685 and 270 vehicles per day north of Route 685. Route 685 has a volume of approximately 140 vehicles per day between Pinegrove Road and its dead end at the north. Note that these relocations are shown only conceptually at this stage. The exact design of these roadways and of the relocated intersection of Route 654 and 685 will be determined at the time of construction drawings review. Additionally, the site access will intersect Route 685 internal to the site. The appropriate configuration for this intersection will be determined at the time of construction drawings review. ---PAGE BREAK--- 0 500' 1000' ENGINEERING EXCELLENCE. ---PAGE BREAK--- DESIGNED BY: DRAWN BY: CHECKED BY: SCALE: DATE: PROJECT NUMBER: REVISIONS P:\2018\1802\0100\18020117\18020117-010303\CAD\18020117-010303_SDI\18020117-010303_Site.dwg July 1, 2019 8:51:01 AM 18020117-010303 MAY 30, 2019 GREEN RIDGE RECYCLING & DISPOSAL FACILITY CUMBERLAND COUNTY, VIRGINIA Engineering Surveying Environmental Services 1030 Wilmer Avenue, Suite 100 Richmond, VA 23227 [PHONE REDACTED] Fax: [PHONE REDACTED] www.daa.com Virginia Beach, VA Raleigh, NC Fayetteville, NC Hampton Roads, VA Charlottesville, VA Blacksburg, VA Northern Virginia SCHEMATIC ROAD & ENTRANCE PLAN & PROFILE 1" = 80' GWC EEH EEH C1.0 1 inch = ft.
