SMART is building a 70-mile passenger railroad and parallel bicycle-pedestrian
path along the publicly owned Northwestern Pacific Railroad right-of-way through
Sonoma and Marin Counties. The rail line runs from Cloverdale, at the north end
of Sonoma County, to Larkspur, where the Golden Gate Ferry connects Marin County
with San Francisco. Along the way, SMART will have stations at the major population
and job centers of the North Bay: San Rafael, Novato, Petaluma, Cotati, Rohnert Park,
Santa Rosa, Windsor and Healdsburg.
CHS is a subconsultant to PGH Wong Engineering, providing design services
for the southern segment from the Larkspur Ferry Terminal to SR-37.
CHS is responsible for traffic engineering design, including traffic signal preemption,
traffic signal coordination and adaptive control, and railroad-highway grade crossing
safety design. Work activities completed include evaluation and implementation of
quiet zones and evaluation of 23 at-grade crossings along the SMART corridor from
Sir Francis Drake Boulevard to the SR-37 interchange, as well as for 17 signalized
intersections in downtown San Rafael. CHS is also responsible for evaluating the potential
of closure for some private crossings. The project requires coordination with SMART, Marin County,
and the Cities of San Rafael and Novato.
