construction on or along traveled County roadways. When roadway or drainage work is <br />to be performed on County roadways that are open to traffic, the contractor will be <br />required to submit a traffic control plan for approval by the County Engineer prior to <br />beginning the work. Traffic control shall follow the guidelines of Section 1-07.23 (Public <br />Convenience and Safety) of the WSDOT Standard Specifications. All barricades, signs <br />and flagging shall conform to the requirements of the MUTCD. Signs must be legible <br />and visible and should be removed at the end of each workday if not applicable after <br />construction hours. <br />B. Temporary Road Closures and Detours: <br />When temporary road closures cannot be avoided the contractor shall post "To Be <br />Closed" signs and place a legal notice in the newspaper a minimum of five working days <br />prior to the closing. The types and locations of the signs shall be shown on a detour <br />plan. A detour plan must be prepared and submitted to the Department of Public Works <br />at least 10 working days in advance of the proposed closure, and approved prior to <br />closing any County roadway. In addition, the contractor must notify, in writing, local fire, <br />school, law enforcement authorities, postal service and any other affected persons as <br />directed by the County Engineer at least five working days prior to the closing. <br />C. Haul Routes: <br />The County Engineer may require the contractor to submit a pavement analysis of the <br />proposed haul route, prior to and immediately after construction ends. The pavement <br />analysis shall be performed by an engineer licensed in the State of Washington. If the <br />final pavement analysis determines that the roadway has been damaged, the contractor <br />shall be responsible for restoration of the roadway. <br />If the construction of a proposed development is determined by the County Engineer to <br />require special routing of large trucks or heavy construction equipment to prevent <br />impacts to surrounding roads, residences or business, the contractor shall be required to <br />develop and use an approved haul route. <br />When required, the haul route plan must be prepared and submitted to the County <br />Engineer and approved prior to beginning or continuing construction. The haul route <br />plan shall address routing, hours of operation, signing, flagging and daily maintenance. <br />If the contractor's equipment or suppliers fail to use the designated haul route, the <br />County Engineer may prohibit or limit further work on the development until such time <br />as the requirements of the haul route are complied with. <br />D. Haul Route Agreement: <br />When identified as a need by the SEPA review process or by the County Engineer, a haul <br />route agreement shall be obtained by the franchised utility, developer or property <br />owner establishing restoration procedures to be performed upon completion of the <br />haul operation. <br />(Ord.2015-010 2015) <br />12.09.O60 County Forces and County Contract Road Inspection. <br />Road construction performed by County forces or by contract for the County will be inspected under <br />supervision of the County Engineer. <br />
