FINANCIAL STATEMENT:

DESCRIPTION: Several months ago, the City Council reviewed a
Caltrans design for a soundwall along the west side of 1-680 from a point just south
of Amador Valley Boulevard, north about 2,900 feet to the Valley Christian School
(formerly Dublin School) playground. The soundwall was to be a concrete block wall
to match the one on the east side of 1-680 near Alcosta Boulevard. The colors were
tan with a cream band near the top and a red column and band accent. At that
meeting, the City Council reviewed and approved the proposed design but requested
that the westerly face of the retaining wall be colored and textured to complement
the soundwallo
In response to the City's request, Caltrans is proposing to color the retaining wall
concrete tan to match the majority of the soundwall and to place rubber form liners
against the wall forms to give a simulated split-face block wall pattern, similar to
the soundwall face. The finished structure would consist of the tan simulated block
retaining wall to a height of 12 feet, atthree-foot gray concrete vehicle barrier,
and a patterned, colored soundwall up to 11 feet on top of the vehicle barrier.
This treatment has been used by Caltrans along 1-680 in Alamo.
The wall face will be the permanent freeway view from the backs of houses on
Ironwood Drive, Honey Court, and Ironwood Court, and from the Lutheran Church of the
Resurrection.
Staff recommends that the City Council review the aesthetics of the wall, receive
comments from the public, and approve the design aesthetics as presented.
