Pavement Preservation
Workshop

What is a Pavement Management Program
(PMP)
PMP = A tool to help make cost-effective decisions
• Answers 3 main questions:
– What is the current condition of our pavement
network?
– What repairs are needed and when?
– How much is required to maintain or improve our
streets cost-effectively?
• Planning Tools:
- MTC Pavement Technical Assistance Program (P-TAP)
- StreetSaver® Software
- City’s Graphic Information System (GIS)
Vallejo’s Roadway Network
• 736 lane miles of streets
– 158 miles of Arterial Streets
– 117 miles of Collectors
– 460 miles of local/residential
• Approx. 7M square yards of asphalt
pavement
• Replacement Value of $1.13B (P-TAP
2022)
• Deferred Maintenance is ~$300M
(P-TAP 2022)
How is Pavement Condition
Measured?
Vallejo’s Overall
PCI = 48
Types of Pavement Distresses
Distresses that affect the PCI of a
street, inspected and documented
in the City’s P-TAP
Alligator cracking
Block cracking
Distortions
Weathering & Raveling Rutting
Longitudinal or
transverse cracking

Incremental Excise Tax: Highway Users
Tax Account (HUTA)
• Streets and Highways Code (SHC) prioritizes the
use of per gallon “gasoline tax”, “diesel fuel tax”,
and “use fuel tax” for designated engineering,
administration and for construction of road and
transportation facilities.
• After a portion is set aside for State Active
Transportation Programs, the remaining balance
is split between local jurisdictions.
• Pursuant to SHC 2103 the balance is distributed
in equal halves as such:
– Counties – Based on ratios of registered vehicles
and miles of maintained county road
– Cities – Based on population size

FY 2022/23
$3,114,827
Senate Bill (SB) 1 Fuel Excise Taxes & Fees
• Pursuant to SB 1 the Road Maintenance and
Rehabilitation Account (RMRA) receives revenue
from the SB 1 portion of gasoline and diesel
excise tax, the Transportation Improvement Fee,
and the entirety of the Road Improvement Fee.
• After set-asides for priority programs
(approximately $750 million annually) the
remaining balance of monthly revenue is split
evenly between the Local Streets and Roads
Program and the State.
– Similar to the incremental excise tax, distributed in equal halves to counties and to cities pursuant to
SHC 2103
– SB 1 funds include oversight by the California
Transportation Commission

Capital Improvement Projects and
Utility Coordination
• In combination with grant
funds, staff utilize pavement
budget as local match
• Staff coordinate pavement
improvements with fellow
agency projects (VFWD, Solano
County Public Works)
• Staff coordinate
interdepartmentally to improve
pavement after utility work

pothole repairs
• City entered into a multi-year
contract
• Over 1,000 potholes repaired
since February 2022
Pavements Deteriorate Over Time
Pavement Preservation
• Other Cities around us have
successfully incorporated new
strategies and techniques
– Pavement Improvement and
Rehabilitation Projects
– Pavement Preservation Projects
– Pavement Preservation
Maintenance
• Approach:
– Applying the right treatment at the right time
– Selecting cost-effective treatments to provide the best pavement for the lowest long-term costs to Vallejo

ASSUMPTION:
• You own 300 lane miles of road &
• Have a budget of $1.5M for:
• pavement reconstruction
• rehab
• maintenance
• Typical Breakdown
• $1M for reconstruction and rehab =“worst first”
scenario &
• $500K for maintenance
2 0
What You Get for $1.5M
•Reconstruction ~ $25 per yd2
• (3”mill and fill with HMA @ $120/ton)
• $1M÷$25/yd2 = 45K yd2 or 5.7 LM
•Cost of maintenance ~ $4 per yd2
• $500K÷$4/yd2 = 125K yd2 or 17.8 LN
Total LN Mi repaired is 23.5
For 300 lane miles, road cycle will be ~13 years
2 1
What If You Flop the Budget Around:
$1M for Maintenance and
$500K for Reconstruct and Rehab
•Costs of reconstruction ~ $25.00 per yd2
• $500K÷$25/yd2 = 20K yd2 = 2.8 LN Mi
•Cost of maintenance ~ $4.00 per yd2
• $1M÷$4/yd2 = 250K yd2 = 35.5 LN Mi
•Total LN Mi repaired ~ 38
•For 300 lane miles, road cycle will be ~ 8 years

Program needs
To reverse Vallejo’s downward Pavement conditions
will require:
1. Increased basic maintenance of crack sealing,
pothole repairs, and patch paving.
2. ADA Curb Ramp program – most treatments for
streets with low PCI trigger ADA compliance (curb
ramps and signal upgrades)
3. Significant increase in roadway resurfacing so that
all streets receive treatment every 8-10 years
Financing Options
• Combined Project needs of $120 million
• Lease Revenue Bonds for up-front cash flow
• 20- or 30-year Terms
• 2-Tranche Strategy (2023 & 2026)
Potential Bonding Scenarios
2 Tranche
Scenarios Pros Cons/Risks
$60M in 2023
$60M in 2026
- Consistent staffing for
6-year period
- Cadence of delivery
- Balances risk and award
- Max ability to deliver
pavement projects is
uncertain
- Ability to spend it all (staff
vacancies/turnover)
$45M in 2023
$75M in 2026
- Slurry & Chip Seal up
front
- Focus on design for
rehab & reconstruct
- Increase staff later
- Heavier construction and
rehab in 2
nd Tranche
- Interest rate levels in 3
years is uncertain
- Ability to spend it all (staff
vacancies/turnover)
$70M in 2023
$50M in 2026
- Costs will be higher
later, so do more now
- More visible to
residents and users
- Requires heavy staffing
levels up front
- Ability to spend it all (staff
vacancies/turnover)

City Council Goals Discussion
4 About Staff Capacity
5 About 90% of the City of Vallejo’s
work plan is established by existing
services and regulatory requirements
Remaining 10% of staff capacity is
available to dedicate toward other
activities (such as goals)
Simply put:Focusing in one direction
often means turning away from
another
For instance: Our team has received around 350 council inquiries or questions, which have required significant attention and diverted staff to address.
Council’s Focused 2022 Goal:
Building Code compliance and plan to
resolve trash, illegal signs and unpermitted
activities
Identify development alternatives for
surplus lands (phase I)
