CENTRAL LOCATION TO COLLECTION ROUTES Consideration; To maximize waste collection efficiency, transfer stations should be located centrally to waste collection routes, As a rule of thumb in urban and suburban areas, Transfer stations should be no more than 10 miles away from the end of all collection routes. Beyond that distance, collection routes might need to be altered to enable refuse to be collected and deposited at the transfer station within one operating shift. Definition; Road mile distance measured from proposed site to waste generation centroid - 2025 Mean Center (weighted by population and employment), 2. ACCESS TO MAJOR TRANSPORTATION ROUTES Consideration; The transfer station should have direct and convenient access to truck routes, major arterials, and highways. Access to rail would also afford additional Transfer and disposal flexibility in the future, It is preferable to avoid routing collection and transfer vehicle traffic through residential subdivision areas because traffic generated by transfer stations contributes to congestion; increased risk to pedestrians; increasetl'air emissions, noise, and wear on roads; and might contribute to litter problems, Definition: Direct or convenient access fo truck routes, major arterials, highways, and/or potential rail or infermotlel access. Major truck routes, arterials, and highways will be defined as 15-501, NC 54, NC 86 (excluding NC 86 north of Hillsborough), US 70, I-40, or I-85. Attachment 1 B Site with shortest road mile distance from Location of waste cenfroid and distance the cenfroitl will be ranked highest. are critical factors in site selection. Distance will be measured using most direct route to proposed site, Route maybe comprised of interstates,highways, major arterials, and street or roadway connectors, Site with most direct or convenient access to truck routes, major arterials, and highways will be ranked highest, Street or roadway connectors must accommodate through traffic with the following functional requirements; Parking-restricted (no parking on road); Major Intersections - trafficsignals & crass street stops; Posted Speed Limit- 35.45 MPH; and Truck Traffic -unrestricted, Potential rail access will be used to further differentiate site rankings (e.g., sites with a lower truck access ranking that have rail access will be reevaluated in terms of final technical ranking.

Definition: ' The minimum site size to be initially considered will be 25 acresas established under the Exclusionary Criteria. Co-location sites with other municipal facilities or operations of less than 25 acres will be considered provided fhaf transporfation,access, buffers, and preliminary transfer station layout and roadway configurations demonstrate the adequacy of a smaller site, e eno~IriG~IT CDnrG cnp nAl CITC Dnnnu~nva nl IGniAlr nAln DnDttlAlr t C...:nn! ..rnv.:ni nnminn n a nnfnninn ~roffin frnm FnnLinn nn4n nntilin rn~rle_ 4. SUFFICIENT SPACE FOR ON•SITE ROADWAYS, QUEUING, AND PARKING Consideration Transfer stations typically have on-site roadways to move vehicles around various. parts of the The site thak lends itself to the most efficient transfer site. Waste collection trucks can be up to 40 feet lohg. Transfer trailers that move waste ' desigh in terms of roadway geometry and to a disposal facility are typically 50 to 70' feet long, These vehicles need wide roadways with' layout will be ranked highest. 'Roadway gradual slopes and curves to maneuver efficiently and safely. Also, the site will need space for widths, maidmum slopes, number of lanes, parking transfervehicles and to allow incoming ahd outgoing traffic to form lines without backing up turning radius, and traffic flow pattern will be onto public roads, considered. Definition: On-site roadways and maneuvering areas will meet the following minimum requirements: down slope vehicle ramps must be less than 10%; upward sloped ramps must be less than 6%; roadway widths for collection vehicle and transfer vehicle traffic must be 24 feet; inbound and outbound collection vehicle queuing (in front of scale) must accommodate 4 vehicles with provisions for a Bauble stack using bypass or outbound lanes (i.e., stage 8 inbound collection vehicles); queuing for 4 transfer vehicles including trailers positioned under load-out hoppers; .staff parking for 5 vehicles plus 2 visitors; and trailer storage for 4 to 6 units.

TRUCKANDTRAFFIGCOMPATIBILITY Consideration: Transfer stations often receive surges of traffic when collection vehicles have fniShetl their routes. Transfer station traffic varies locally'but tends to peak twice a day. The first peak'is often near the middle of the day or shift, and the second at the end of the day or shift, Th"erefore the$est sites for transfer stations are located away from areas that have midday traffic peaks and/or school bus and pedestrian traffic. Definition:- . Compatibility of projected transfer station Traffic volume and, vehicle types with existing traffic mix and flow patterns in the immediate area of the site, Site's with street or roadway connector access that do not currently or are'not projected inthe futureto exhibitsignificant midday traffic peaks and school biis or pedestrian traffic shall be ~ahked highest Land use and development within one half mile radius of proposed site will be used to assess potential compatibility issues related to connector streets and roads, Truck and traffic compafibility -critical consideration -particularly with respect to the Eubanks Road area. OUTBoard requests that the transfer station not be sited on a priority bicycle route. Additionally, the route to the transfer station should minimize proximity to any bicycle route and avoid travel over a priority bicycle route, 6.

BUFFER SPACE Considerafiom To mifigate the impact on the surrounding community, a transfer station should be located in an area that provides separator from sensitive adjoining land uses andlor residences: Buffers can be natural or cohstructed and cari take many forms; including open spaces, fences, sound ir/alls; trees,'berms, and landscaping. Defniton: Presence of natural areas, trees, topographic relief,. or other features that provide separation from adjoining land use or residences A site with the largest available undeveloped footprint (acres)not including a minimum 100-foot bufferarountl the perimeterof the site and dedicated transferstation area (station, roadways, parking areas, scale facilities, and other required site improvements for transfer operations) will be ranked the highest. A site that provides the most buffer width in terms of wooded area or other natural screening feature(s){i.e., streamshills, eta) around the perimeter of the property will be ranked the highest, Page 4 Size for Transfer funcfion only. Provide minimum 100•foot buffer width. Buffer width and what is being buffered should be considered in combination in terms of establishing final buffer requirements. Maintain integrity of existing wooded areas and hardwood trees in maintenance of perimeter buffers, Attachment 1 B Attachment 16 BOCC Work Session - 06/16/08 Attachment 1 B f 9: GENTLY SLOPING TOPOGRAPHY Consideration: Transfer stations often are multi-level buildings that need to have vehicle access at several levels.
