DESCRIPTION:
This Capital Improvement project consists of two separate contracts. One of
the contracts provided for the construction of a wood soundwall on the west
side of San Ramon Road. The other contract provided for the construction of
a masonry block wall on the east side of San Ramon Road, both sides of
Amador Valley Boulevard east of Village Parkway, and along the west side
Dougherty Road at Arroyo Vista. The San Ramon Road soundwalls were
constructed as noise mitigation for the road widening project. The Amador
Valley Boulevard soundwalls were constructed primarily as a beautification
measure, as these walls replaced the deteriorated wooden fences installed in
the early 1960's by the original subdivider. The Dougherty Road soundwall
provides sound mitigation for Arroyo Vista residents and was financed by the
Housing Authority and Community Development Block Grant funds.
The most significant problem with these projects occurred when the block
wall along San Ramon Road was delayed by a conflict with underground utility
lines that were located too close to the original site for the wall. The
soundwall was originally intended to be built entirely within the public
right-of-way but had to be moved back to the private property line, and
Staff was required to obtain easements from the property owners.
Both projects have now been completed in accordance with the approved plans,
specifications, and modifications, and Staff recommends that the City
Council accept the projects, authorize a budget transfer in the amount of
$28,218 from unallocated reserves, and authorize final payment to B and B
Concrete in the amount of $16,638.16.
