10.40.010 Maximum Speed Limit of Twenty-Five Miles Per Hour Unless Otherwise Posted.

The maximum speed limit for all County roads is established as 25 miles per hour except where a lower or greater maximum lawful speed is established by County ordinance or by State statute. (Ord. 85-144 § 1 (part), 1985)

10.40.020 County Engineer to Maintain List of Certain County Roads With Designated Speed Limits.

The County Engineer shall maintain a list of certain County roads with a designation of the maximum speed limits thereon as established by ordinance of the Pierce County Council. The list shall be kept on file in the offices of the County Engineer. Said list shall be made available to the public during all normal business hours. The maximum speed limit on all County roads not included in the listing is 25 miles per hour as specified in PCC 10.40.010. (Ord. 89-150 § 1 (part), 1989; Ord 87-79 § 1, 1987; Ord. 85-144 § 1 (part), 1985)

10.40.030 Traffic-Control Devices.

The County Engineer is directed to post County roads with the proper traffic-control devices to regulate the maximum speed limits as adopted by ordinance and said speed limits shall become effective when posted. The maximum legal speed limit on any county road or portion thereof which is not posted with a regulatory speed limit sign is 25 miles per hour. (Ord. 89-150 § 1 (part), 1989; Ord. 85-144 § 1 (part), 1985)

10.40.040 School Zones.

The County Engineer is directed to mark school zone speed limits as established by RCW 46.61.440 and as established below.

The County Engineer is authorized to evaluate County roadways within a designated school zone and, when deemed appropriate by a traffic engineering review, may establish by written authorization with a 14-day notification to the Council prior to implementation, a school speed zone along a County roadway. This authority does not preclude the Council from establishing other school speed zones that it may deem appropriate or otherwise altering or revoking any such zones which may have been established by the County Engineer.

Active warning devices (such as flashing lights) are encouraged to be installed at all new school speed zone locations on County arterial roadways. It is the responsibility of the school district to provide, install, and maintain the active warning devices and signs per County standards and requirements, and to obtain written approval from the County Engineer for all such installations that are within the County right of way. The devices may only be in operation for the periods when children are in the process of transiting to/from school, generally not to exceed 45 minutes in duration for each activation, or as otherwise approved by the County Engineer. The County Engineer may periodically coordinate with the school district to ensure the warning devices are properly maintained and operated. School speed zones may be revoked by the County Engineer if any of these requirements are not satisfied or maintained.

The speed limit in a posted school speed zone is 20 miles per hour when school speed zone flashing warning lights are in operation or when other designated signing shall indicate (such as “When Children are Present”), as defined by WAC 468-95-330 and 468-95-335. (Ord. 2018-58 § 1, 2018; Ord. 85-144 § 1 (part), 1985)

10.40.050 Infractions and Penalties.

Any person traveling on any County road at a speed in excess of the maximum speed limit shall have committed a traffic infraction and shall be liable for monetary penalties as set forth in RCW Chapter 46.63. (Ord. 85-144 § 1 (part), 1985)

10.40.060 Temporary Decreases During Construction.

The County Engineer is delegated limited authority to implement a temporary speed limit reduction for County arterial roadways during active construction or repair when it is deemed appropriate to enhance safety to the public. Such reduction shall require a traffic engineering study and the County Engineer shall then issue a written authorization for such reduction, and shall provide a copy of the authorization to the Council at least 14 days in advance of the implementation of the reduction. The Construction Zone Speed Limit shall:

A.    not be less than 25 miles per hour;

B.    not exceed a 10-mile-per-hour reduction from the normal posted regulatory speed limit;

C.    not extend outside the signed construction project traffic control limits;

D.    not occur outside the active construction or repair activity limits; and

E.    be removed when the road project is completed to the point where normal traffic flow can reasonably be accommodated.
