4. 65% Design
4.2 Roadwav Desiqn
Dokken Engineering will perform additional roadway design for the traffic calming measures, sidewalk
curb ramp replacements and a complete drainage system replacement on Sixth Street from Railroad
Street to Rogers Lane. This level of improvements was not anticipated with the original scope of
services. As the Traffic Management Plan (TMP) evolved, it was determined that curb extensions would
be added to nearly the entire corridor, not simply a few select locations. Furthermore, the City desired
that there be no leaf and debris traps between the curb extensions and the existing curb/gutter.
Therefore, a complete replacement of the existing drainage system must be designed to relocate the
drop inlet locations. Other additional elements of the'TMP to be designed include structural gateway
features at each end of the neighborhood.
4.7 Street Liqhtinq Desiqn
Dokken Engineering will design a new street lighting system for Sixth Street from Railroad Street to
Rogers Lane. The new system will be enhanced aesthetic lighting similar to Monterey Street with
luminaires on both sides of the street for a better distribution of light.
The street lighting design will include design of two lighted crosswalks. The Sixth Street lighted
crosswalks will be push button activated and located at the Railroad Street and Rogers Lane crosswalks.
4.9 City Trail Desiqn and Waterline Relocation
During the development of the project, it was determined that the City Trail along the Ronan Channel
through the US 101 interchange should be designed and constructed with the Camino Arroyo Bridge
Project. The original scope of services included planning concepts and support of the trail planners, but
not design.
Dokken Engineering will perform the following design services for the City Trail. First, design an
appropriate structural section for the trail on the native material and for the Sixth Street Overcrossing
embankments. Second, expand the roadway grading to include the necessary earthwork for the City
Trail. Third, make revisions to the striping along Sixth Street and Gilman Avenue to accommodate the
trail. And lastly, design and obtain approval from Caltrans for revisions to the Sixth Street
Overcrossing sidewalks, lanes and barriers to accommodate the trail. This is anticipated to require a
Caltrans Encroachment Permit for construction.
Dokken Engineering will design the relocation of the City waterline at the base of the Sixth Street
Overcrossing embankment. This relocation is necessary to facilitate the widening of the approach
embankment for the City Trail
