RECOMMENDATION(S):

ADOPT Traffic Resolution No. 2017/4455 to prohibit vehicles over 40 feet in length on Pinehurst Road (Road No. 2631A), as recommended by the Public Works Director, Canyon area.

FISCAL IMPACT:

No fiscal impact.

FISCAL IMPACT: (CONT'D)

BACKGROUND:

Pinehurst Road is a narrow canyon road with numerous vertical and horizontal curves, including two sharp hairpin turns nearer to the northern end. There have been 26 traffic collisions on this roadway since 2009, including four collisions involving bicyclists. We have been informed of larger trucks having been "stuck" on the hairpin turns, causing a nuisance and safety hazard. State-standard truck (WB-40) turning templates show that vehicles over 40 feet in length cannot negotiate the hairpin turns without encroaching into the opposing lane. Prohibiting such vehicles from Pinehurst Road will enhance traffic safety for drivers of these larger vehicles as well as other road users, including motorists and bicyclists. Pinehurst Road terminates at its southern end at Redwood Road, in Alameda County. The Alameda County Public Works Department has been contacted regarding this vehicular restriction. Coordination efforts to inform the public of vehicular restrictions with signage on the roadway will continue on the roadway.

CONSEQUENCE OF NEGATIVE ACTION:

Vehicles over 40 feet in length will not be prohibited from using Pinehurst Road.
