DESCRIPTION: The annual overlay program consists of placing at least a
1 1/2" asphalt overlay on streets that are in a deteriorated
condition. A special pavement fabric will also be placed over the travelway
prior to the asphalt overlay. This fabric helps bridge the existing minor
pavement cracks and prevent the reflection of cracks through the new asphalt.
Before installing the overlay, the pavement failures are dug out to the base
rock and replaced with a new section of asphalt.
In order to stay within the existing Overlay and Street Repair Budget, and
still receive the maximum amount of funds from the State-Local Transportation
Partnership Program, Staff is proposing to integrate this year's funds for the
Slurry Seal Program into the Overlay Program. This procedure, which increases
the total amount of funds available for the overlay project, will enable the
City to utilize the maximum State SB 140 Program of $104,125. The result will
be a Two-Year Overlay Program this fiscal year and no Slurry Seal Program,
with the ability to capture an additional $38,245 in SB 140 monies over the
budgeted $65,880.
The streets to be overlaid are:
Peppertree Road (Shannon Avenue to West Vomac Road)
Shannon Avenue (Vomac Road to Peppertree Road)
Vomac Road (Cavalier Lane to San Ramon Road)
Bellina Street (Galtndo Drive to San Ramon Road)
Deervale Road (Bellina Street to Vomac Road)
Starward Drive (Amador Valley Blvd. to Vomac Road)
Sierra Lane (Sierra Court to Dougherty Road)
Donohue Drive (Hillrose Avenue to Amador Valley Blvd.)
Amarillo Road (Hansen Drive to Silvergate Drive)
Betlen Drive (Hansen Drive to End)
Silvergate Drive (Hansen Drive to Dublin Blvd.)
The second phase of the Dougherty Road Bike Path is being included with this
year's overlay program in an attempt to save money from the economy of scale
of combining two asphalt related projects. This phase continues construction
of the bike path on the east side of Dougherty Road between Amador Valley
Boulevard and Willow Creek Drive. The bike path is funded by a $75,000 grant
from the Transportation Development Act (TDA).
Due to a sight distance problem at Wildwood Road and Dougherty Road, Staff is
proposing to extend the bike path (approximately 600 feet) to Willow Creek
Road this year to make the crossing to Alamo Creek Park. This could possibly
cause the project to increase in cost by approximately $10,000. However, the
City has been able to reduce the amount of General Fund monies originally
budgeted for the overlay project and slurry seal as a result of obtaining
additional SB140 funding. This difference could be used to cover the
additional bike path cost.
In addition to the striping on the streets to be overlaid, the following
streets will also receive thermoplastic striping.
Davona Drive (Alcosta to Village Parkway)
Stagecoach Road (Turquoise to City Limit)
West Vomac/Southwick (San Ramon Road to Alcosta)
Clark Avenue (Dublin Blvd. to Maple)
The initial cost of thermoplastic striping is significantly higher than the
cost of paint; however, a cost savings is realized over a period of time as
the thermoplastic has approximately 10 times the life of today's water-based
traffic paint.
Notices are sent out prior to the beginning of work in order to advise the
residents that construction will take place on their street.
