TO: Mayor and Town Council September 12, 2023
SUBJECT: Pavement Management for Arterial Streets
INTRODUCTION
During the review of the draft Capital Improvement Program (CIP) last May, the issue of
ongoing maintenance of the Town’s major arterial streets was raised. The Town’s
Pavement Management Program addresses ongoing pavement maintenance of local
residential streets. Historically, the Town has been successful in securing federal, state
and regional funds toward reinvesting in the roadway network for “major” and “minor”
arterial streets. Changes occurring with respect to ongoing availability of such funds
along with the criteria used for potential allocation, are making Town efforts to qualify
for such funds increasingly difficult.
The purpose of this memorandum is to discuss the current condition of the Town’s major
arterial roadways along with potential options to treat and fund necessary pavement
management costs.
BACKGROUND
The Town is responsible for the maintenance of its major arterial roadways, which play
a vital role in the overall transportation network. Ensuring the safety and functionality of
these roads is a top priority for the Town. To this end, all streets maintained by the Town
are inspected every two years to assess their condition, assign a Pavement Condition
Index (PCI), and prioritize necessary improvements. The Town has five major arterial
roadways as part of its roadway network:

Arterial Paving Discussion 2 September 12, 2023
The Town’s Capital Improvement Program (CIP) includes projects:
•C-600 - San Ramon Valley Boulevard Improvements;
•C-601 - Camino Ramon Improvements;
•C-602 – Danville Boulevard Improvements; and
•C-635 - Sycamore Valley Road Improvements
The roadway network also includes several minor arterial roadways, including:
•Diablo Road from Hartz Avenue to Green Valley Road
•El Cerro Boulevard
•Danville Boulevard
•Hartz Avenue
With the exception of Hartz Avenue from Diablo Road to Hartz Way, all minor arterial
roadways have recently been resurfaced and require no immediate treatment.
DISCUSSION
In general, the following table provides an example of the general treatment strategy
based on the range of pavement conditions.
Condition
Category
Pavement Condition Index (PCI) General Treatments
Strategy Upper Limit Lower Limit
Excellent 100 85 Do Nothing/Corrective
Maintenance
Good/Fair 84 60 Preventative
Maintenance/Resurfacing
Poor 59 40 Rehabilitation
Failed 39 0 Reconstruction
Current Paving Conditions, treatment options, and costs
C-600 - San Ramon Valley Boulevard: San Ramon Valley Road Improvements, CIP C-600 is
scheduled for resurfacing in 2024 with a slurry seal application for the section south of
Sycamore Valley Road, and an overlay for the section north of Sycamore Valley Road.
The PCI will be 100 once complete. The project is currently funded for $2.12 million
through a combination of Measure J and OBAG II funds. Based on the most current cost
estimates, there is an estimated shortfall of approximately $1.0 required to construct this project.
C-601 - Camino Ramon: Camino Ramon Improvements, CIP C-601 is now complete. This
$2.7 million project was funded through a combination of Measure J, OBAG II, SAFETEA-
LU and Pavement Management funds. With a PCI of 100, this roadway is not expected
to receive another treatment for 15-20 years.
Arterial Paving Discussion 3 September 12, 2023
C-635 - Sycamore Valley Road: This includes the roadway segment that runs east of I-680
from the freeway to Camino Tassajqra, a distance of approximately 1.3 miles. Attributable
in part to the extraordinary winter 22/23 storms, the average PCI for this roadway
segment is 56, indicating a notable level of pavement deterioration. Despite its
suboptimal condition, this project is not currently funded in the CIP. Considering the
current roadway condition, the options available for consideration consist of an all or
nothing approach, as described below:
1.Pavement Rehabilitation option (overlay) – This would involve grinding down
existing pavement and replacement with a 3-inch pavement overlay. Total
estimated cost is $3.05 million
2.Status Quo (take no action) – At this point, anything less than the Pavement
Rehabilitation option is infeasible. Under the status quo option, the estimated
remaining life expectancy of this roadway is approximately seven years, after
which time rehabilitation is no longer an option and the roadway will require
reconstruction. The estimated reconstruction cost based upon 2023 dollars is
approximately $5.34 million.
Camino Tassajara: Camino Tassajara runs from Sycamore Valley Road, east to the Town
limits in the vicinity of Lawrence Road, a distance of approximately 4.2 miles. Overall
average PCI is currently 80, placing it within the good condition category. In order to
preserve the pavement condition for as long as possible, the following options are
available. These include additional options that have not previously been employed by
the Town.
1.Perform preventative maintenance – Perform crack sealing and digout repairs as
necessary for the next 5-7 years until reaching the lower limit of the “good”
condition category at which point a slurry seal would be applied. Estimated
annual cost of $50,000 for seven years.
2.Resurfacing (slurry seal) – Resurface the roadway with slurry seal. This would
extend the life of the pavement seven to ten years. The estimated cost in 2023
dollars is approximately $4.2 million.
3.Status Quo (take no action)
o Based on projections, Camino Tassajara would require rehabilitation (3 inch
overlay) in approximately 10-12 years. The estimated cost in 2023 dollars is
approximately $12.1 million.
o Based on projections, Camino Tassajara would require reconstruction in
approximately 18 years. The estimated cost in 2023 dollars is approximately
$21.2 million.
Crow Canyon Road: Crow Canyon runs from Blackhawk Road to just east of Tassajara
Ranch Drive, a distance of approximately 0.5 miles. This roadway segment has an
average PCI of 75. This arterial is also considered in the “good” condition category and
has similar options as Camino Tassajara:
Arterial Paving Discussion 4 September 12, 2023
1.Perform preventative maintenance – Perform crack sealing and digout repairs as
necessary for the next 5-7 years until reaching the lower limit of the “good”
condition category at which point a slurry seal would be applied. Estimated
annual cost of $15,000 for seven years.
2.Resurfacing (slurry seal) – Resurface the roadway with slurry seal. This would
extend the life of the pavement seven to ten years. The estimated cost in 2023
dollars is approximately $471,000.
3.Status Quo (take no action)
o Based on projections, Crow Canyon Road would require rehabilitation (3 inch
overlay) in approximately 8-10 years. The estimated cost in 2023 dollars is
approximately $1.2 million.
o Based on projections, Crow Canyon Road would require reconstruction in
approximately 18 years. The estimated cost in 2023 dollars is approximately
$2.1 million.
Crack Sealing Treatment
The Town’s ongoing efforts to maintain and preserve its roadways, has not previously
included performing standalone crack sealing treatment, largely owing to aesthetic
concerns. However, crack sealing offers several advantages, including preventing
moisture infiltration, which can lead to further deterioration, preventing the growth of
vegetation within cracks, reducing the likelihood of further damage, and extending the
lifespan of the pavement, reducing the need for more costly repairs in the future.
Funding Availability
As previously described, arterial roadway maintenance has relied upon the Town’s
ability to qualify for and secure various grants. However, recent trends have seen a
decrease in grant availability for standard roadway projects, with a focus on active
transportation projects and those benefiting disadvantaged communities.
An application was submitted for Sycamore Valley Road Improvements for the latest One
Bay Area Grant Cycle 3 (OBAG 3). Unfortunately, it ranked 22nd out of 29 projects
evaluated, with only the top 10 projects being nominated for funding. The OBAG 3 cycle
allocated a total funding of $26.5 million, while $111 million in total funding requests
were made by various jurisdictions in Contra Costa County.
Special Revenue Funds
Southern Contra Costa (SCC) Subregional is a restricted funding source that lists
Sycamore Valley Road and Camino Tassajara pavement rehabilitation as part of the
limited scope. There is currently an available balance of approximately $1.03 million in
SCC Subregional funds.

Pavement Management CIP C-610
Pavement management funds have traditionally been allocated to resurface residential
streets using general funds and gas taxes. As mentioned above, grants have been
typically obtained for arterials based on their functional classification due to their higher
traffic significance. This distinction arises because residential streets often don’t meet the
criteria for grant eligibility, given their lower traffic volume and localized nature. The
Pavement Management Program currently holds available funds totaling $9.5 million,
which have been partially committed as follows:
•$1.5 million for 2023/24 Slurry Seal – currently out to bid
•$3 million for 2023/24 Pavement Overlay – scheduled for spring 2024
Funding Options Summary
The following describes potential funding that could be used towards the current
shortfall of funding for arterial paving:
•SCC Subregional Funds (Sycamore Valley Road): $1.03M
•Remaining Pavement Management Funds: Up to $5M.
•Other uncommitted CIP General Purpose funds
Future Funding Considerations
Considering the evolving grant landscape and the diminishing availability of grants for
standard roadway projects, staff will continue to explore alternative funding strategies
for future arterial pavement preservation. This may involve recommending allocating
additional general funds to a dedicated arterial paving CIP for this purpose or utilizing
the Pavement Management Program funds strategically.
RECOMMENDATION
Receive the report and provide direction to Town staff on arterial road paving.
