DESCRIPTION:
The City Council approved combining two soundwall projects for Fiscal
Year 1987-88's Capital Improvement Program. These are (1) the replacement of
the deteriorated wooden fences along Amador Valley Blvd. between Village
Parkway and Stagecoach Road for those properties which back onto Amador
Valley, and (2) the addition of soundwalls along the east side of San Kamon
Road as a mitigation for noise impacts from the improvement of San Ramon Road
between Silvergate Drive and Alcosta Blvd.
This proposed project does not include the improvement to the wood
fences on the west side of San Ramon Road nor the~short sound barrier at the
proposed east shoul_der of the improved San Ramon Road, both of which will be
handled separately.
The action being requested at this time is establishment of the type of
masonry wa11 and the exterior face design, not precise determination of the
height or location elements.
The next step in the process for the Amador Valley Blvd. wall wi11 be to
solicit easements from those properties which~back onto Amador Valley between
Village Parkway and Stagecoach Road. Once the Federal Highway Administration
approves the San Ramon Road,improvement environmental document, Staff will
request approval from the City Council regarding the location and size of the
walls, and then for authorization to advertise for bids for the combined
projects. ~
Staff has met with representatives from three prefabricated masonry wall
manufacturers and obtained cost estimates and taken pictures of a number of
wa11s. The manufacturers are Printex, Sierra Precast, and Best Block/Tomax.

Two firms construct 4-inch thick concrete precast walls, while the third
builds their wall of hollow concrete blocks and fills the voids with
reinforcing bars and mortar.
Staff will show slides of the various wal_ls by manufacturer, in order of
ascending estimated cost, and request that the City Council provide direction
regarding the type and facia treatment desired.

Dear Residents and Property Owners:
The Dublin City Council recently approved the 1986-91 Capital
Improvement Program budget, which included construction of concrete or
masonry walls as a noise mitigation measure along the east side of San
Ramon Road and also as a replacement for the deteriorated wooden fences
along Amador Valley Blvd. between Village Parkway and Stagecoach Road as
part of the City's proposed improvements for Fiscal Year 1987-88.
City Engineering Staff will make a presentation to the City
Council at the regular meeting of August 24th regarding the various
fascia treatments and types of soundwalls that may be appropriate for
these locations and ask for the Council's direction toward selecting the
type of wall to be constructed. (The wooden walls proposed for the west
side of San Ramon Road will not be discussed at this meeting.)
This letter is being sent to those residents and property
owners whose rear or side property line adjoins the east side of San
Ramon Road or whose rear property line adjoins Amador Valley Blvd.
between Village Parkway and Stagecoach Road. You are invited to attend
this City Council meeting to view the presentation and provide input
toward the selection of the wall design.
The meeting will be held at 7:30 p.m. at the Dublin Library
Meeting Room, 7606 Amador Valley Blvd. Please feel free to call the
City Engineering Department at 829-4927 if you have an questions.
Sincerely yours,
Lee S. Thompson
