2008-023 <br />(f) Haul routes or haul route segments shall be paved if the anticipated project haul <br />truck traffic from the proposed mine and approved mines sharing the same haul <br />route segment(s) exceed an average of 750 truck trip ends per day. (Truck trip ends <br />are one -directional. For example, one truck entering the mine = 1 trip end; the same <br />truck leaving the mine = a 2°d trip end.) Applicants may enter into a developers <br />agreement to equitably share or recoup paving costs. <br />1. Paved haul routes shall meet the following specifications: <br />a. Minimum pavement width shall be 24 feet. <br />b. Pavement thickness base and sub -base depths shall meet county <br />thoroughfare and truck route specifications, including ESAL (equivalent <br />single axle loads) and pavement strength co-efficients. <br />(g) The county's adopted level of service (LOS) for the project haul route and <br />intersections significantly impacted by project truck traffic shall be evaluated using <br />passenger car equivalents (PCE's) for anticipated haul truck traffic based on <br />Institute of Transportation Engineer's GTE) standards for PCEs. (For example,.a <br />PCE of 2.3 passenger cars per haul truck would be used to evaluate the LOS for the <br />project haul route and intersections impacted by the project.) Such evaluation shall <br />use average daily haul truck traffic plus a 15% (fifteen percent) peaking factor. <br />Where a haul route segment(s) is shared by more than one mining operation, haul <br />truck traffic from all the mining operations shall be used in the LOS evaluation. <br />(h) To provide gaps in haul truck traffic on haul routes and prevent significant haul <br />truck back-ups at haul route/major road intersections, the following truck frequency <br />standards shall be satisfied: <br />1. A mining operator shall limit the frequency of haul truck trips to and from his <br />mining operation on two-lane roads to no more than 120 trip ends per hour, <br />with trips ends as defined in Section 4(f) above. This frequency standard may <br />be exceeded for delivery of materials to special or large projects if the operator <br />first obtains approval from the Public Works Director of a maintenance of <br />traffic plan. Such plan shall include a coordinated hauling schedule if a <br />shared haul route is used and method of maintaining acceptable traffic flow to <br />provide "gaps" for non -project traffic along the haul route. Said plan may <br />also require additional improvements to or security for maintaining the haul <br />route, and may require coordination with other mining operators. <br />2. Along a two-lane haul route segment, cumulative haul truck trips shall not <br />exceed 240 trip ends per hour, with trip ends as defined in Section 4(f) above. <br />3. To aid the county in monitoring haul truck trip frequency, applicants shall <br />provide haul truck log information to the Public Works Director or his <br />designee, upon request. <br />Double Underline Text: Non Workshop Changes <br />Bold Underline: Additions to Ordinance <br />Strike through: Deleted "Text from Existing Ordinance <br />1=:ACommunity Development \Users\CurDevAORDINANCE\2008\2008- <br />934 Excavation(aflerl2-19-08).RTf <br />13 <br />
