§ 13.56.370. Traffic Control.

A.

When it is necessary to obstruct Traffic by any Work proposed within the traveled way, Traffic Control and a plan developed in accordance with the MUTCD shall be submitted to the County prior to starting Work, and shall include provisions to provide temporary pedestrian accessibility in accordance with Americans with Disabilities Act, any regulations promulgated thereunder, the MUTCD, and any other applicable state or federal law. No Permit will be issued until the plan is accepted by the County. The Permittee shall implement the accepted plan, when necessary, until all Work that impacts Traffic has been completed. If conditions change, the Traffic Control plan shall also reflect the changes. A copy of the accepted Traffic Control plan shall be located on the construction site Traffic Control devices are to be supplied by the Permittee.

B.

The Permittee shall be responsible for the safety and security of the traveling public and the security of each Facility within a Road construction zone.

C.

All Traffic Control personnel shall follow the applicable federal, state and local guidelines for their associated working conditions.

D.

During any Work, barriers and warning signs shall be erected, lighted and maintained as necessary or as directed by the Director for the protection of the traveling public. The MUTCD shall be used as a guide for all maintenance and construction signing. During non-work hours, all construction Work area signs that are not appropriate shall be removed or covered. Any deficiencies noted by the County shall be corrected immediately by the Permittee. If Permittee is not available or cannot be found, the County may make such corrections and the Permittee shall pay the actual costs, plus fifty percent of the amount thereof.

E.

At the site of an emergency or whenever necessary for public safety, the Permittee and/or Owner shall employ flaggers, whose duties shall be to control Traffic around or through the construction site or the site of an emergency. The use of flaggers will be governed by the provisions of the MUTCD and may be required in other cases at the discretion of the Director. The County may hire or use County forces to provide Traffic Control or bring the Traffic Control up to the safety standards set out in the MUTCD and other applicable federal and state law at the Permittee's expense (actual cost plus fifty percent).

F.

Unless approved by the Director, the Permittee shall not impede rush hour traffic on arterial or collector Roads during the morning or evening rush hours. No traffic lane shall be closed during the hours of 7:00 a.m. to 9:00 a.m. or 3:30 p.m. to 6:00 p.m., without the approval of the Director.

G.

When Road closures and detours cannot be avoided, the Permittee shall request approval from the County a minimum of twenty-eight days notice prior to the proposed closure, or longer if special circumstances exist (see Section 2. below). It shall be the responsibility of the Permittee to notify and coordinate all Work in the public rights-of-way with police, fire, ambulance, transit organizations, schools and other entities, as determined in the Director's reasonable discretion. The County requires a detour plan to be prepared, submitted and accepted prior to closing any portion of a County Roadway.

1.

The Road closure plan, at a minimum, shall include a detour route with the location and type of signs to be used, pursuant to the MUTCD. A written statement describing the detour route, length of detour and proposed dates and times of Road closure shall also be submitted.

2.

All Road closures shall be consistent with Chapter 47.48 RCW, as enacted or subsequently amended. Special consideration needs to be given by the Permittee concerning the timing requirements of Road closures as specified in Chapter 47.48 RCW and the timing requirements for the Board to review and approve the closure.

H.

For nighttime Work, area flood lighting shall not be allowed to spill out of the Work area in such a way as to disturb, annoy, or endanger the comfort, health, or peace of others, unless necessary for protection of the workplace. Traffic Control devices must be reflectorized and illuminated or have barricade warning lights.
