Annual Overlay & Repair Program
of the City's Annual Overlay Program.
BACKGROUND
Tukwila owns, operates, and maintains just over 200 lane miles of paved asphalt roadways.
Public Works must understand and be able to forecast which roads need maintenance before
full repair is needed. Normal pavement maintenance is done in the form of an overlay, which
can be done at a fraction of the cost of a complete overhaul or replacement of failed pavement
and subgrade. One dollar spent for maintenance saves eight dollars from being needed to
reconstruct a road. Staff maintains a database that includes dates when roads have been
overlaid and current pavement conditions. That database allows staff to project when road
sections may need an overlay.
A key piece of data is the Pavement Condition Index (PCI) of the road surface. A PCI study is
conducted using pavement management consultants every 4 or so years. The study is made up
from data collected by a van driving all roads in the City looking for signs of deterioration and
distress such as cracking, rutting, surface wear, humps, bumps, and sags.
DISCUSSION
The most recent PCI Report from 2020 indicates the leading cause of pavement failure comes
from: heavy side -loading garbage and recycling trucks; school buses; and delivery vehicles — a
typical pattern seen across most cities. The attached PCI Report discusses the current
conditions of Tukwila's street network and how the PCI rating was developed and applied. The
Report also shows that Tukwila's overall average pavement condition score is slightly above the
national average but will require more than the current $1.05M annual construction budget to
maintain the strong number.
The executive summary conclusion from the 2020 Report says: "The Tukwila network has an
average PCI of 65.6 and a backlog of 1.3%, with most of the network landing in the Very Good
PCI range. With the City's existing budget, the network conditions will degrade into the high 50s
PCI range and backlog will continue to grow over time. It is worth noting that the City does have
a fair amount of streets approaching the end of their lifespan where overlays can be effective
representing a percentage of the network at the steepest part of their deterioration curves."
FINANCIAL IMPACT
The Annual Overlay Projected funding comes from the Solid Waste Utility Tax. Tukwila is not
eligible for most overlay grants but has been recently awarded federal grants for three roads on
the National Highway System.

4.2 TUKWILA NETWORK CONDITION IMAGERY
The images presented below provide a sampling of the Tukwila streets that fall into the various condition
categories with a discussion of potential rehabilitation strategies.
Very Poor (PCI = 0 to 25) — Complete Reconstruction
62nd Avenue from 151st Street to South 151st Street (GISID 1004, PCI = 25) — Rated as Very Poor, this
street displays spreading base failure as evidenced by the severe alligator cracking and patching. It is
also worth noting that the patching along the left hand side of the street has severely deteriorated as
evident by the alligator cracking surrounding the patched areas. A mill and overlay on this street would
not be suitable as the base has failed and would not meet an extended service life of at least 15 years.
This street requires a full reconstruction and should be carefully monitored.
Deferral of reconstruction of streets rated as Very Poor will not cause a substantial decrease in pavement
quality as the streets have passed the opportunity for overlay -based strategies. Due to the high cost of
reconstruction, Very Poor streets are often deferred until full funding is available in favor of completing
more streets that can be rehabilitated at lower costs, resulting in a greater net benefit to the City. This
strategy however must be sensitive to citizen complaints forcing the street to be selected earlier. In
addition, this type of street can pose a safety hazard for motorists, since severe potholes and distortions
may develop. It is important to consistently monitor these streets and check for potholes or other
structural deficiencies until the street is eventually rebuilt.
IMS Infrastructure Management Services Tukwila_Report Page 15
7
Fair (PCI = 50 to 60) — Thin to Moderate Overlays
Interurban Avenue From Macadam Road to Gateway Drive (GISID 1998, PCI = 53) — Rated in the Fair
category, these streets require thin to moderate overlays for asphalt when they enter their need year
(generally within 2-3 points of the lower PCI in the defined range). Several distresses are present, but
tend to be more localized and moderate in severity, and non -load related (primarily longitudinal and
transverse cracking and raveling). On this segment of road, the signs of deterioration are evident in the
right hand travel lane of the pavement and are moderate in severity indicating the base has not yet failed
along the entire length of roadway. The curb line is straight through the sidewalk could benefit from some
preventative maintenance to prevent damage from weed intrusion.
Asphalt streets rated as Fair tend to receive a lower priority when developing a rehabilitation program. If
deferred, the rehabilitation cost would only increase by about $3 to $5/yd2, again depending on the
functional classification, in about 5 to 10 years. This delay represents a 20% difference over the time
stated. Thus, the cost of deferral is low when compared to deferring a thick overlay to a reconstruction
with a two to threefold increase in cost.

1.0 EXECUTIVE SUMMARY & RECOMMENDATIONS
PROJECT SUMMARY
In 2020 IMS Infrastructure Management Services, LLC (IMS) was contracted by the City of Tukwila to
conduct a pavement condition assessment and analysis update on approximately 80.5 centerline miles of
City maintained asphalt roadways.
IMS mobilized their Laser Road Surface Tester (RST) to conduct an objective assessment using industry
standard pavement distress protocols such as those found in ASTM D6433-11. At that time, the City's
network average Pavement Condition Index was found to be a 66 and the City's backlog (roads below a
PCI of 40) was at only 1%. See section 4 for more information

As seen in Figure 1, Tukwila has just over 80 centerline miles of roadway, encompassing nearly 1.6M
square yards of pavement surfacing, which is predominantly asphalt. At an average replacement cost for
a typical roadway just over $1.8M per mile, not including the value of the land, the City has over $145M
invested in its paved roadway network.

SUMMARY METRICS OF HEALTH
Pavement Condition Index (PCI) — The PCI score is a ranking assessment on the overall health of a
pavement segment on a scale of 0 to 100. The network average PCI is a good global indicator of a
network's overall health. (Explained in section 4)
Percent of Excellent Roads — Roads with a condition category of Excellent are those that score
between a PCI of 85 to 100.
Backlog —Backlog is the Very Poor and Poor roads (between a PCI of 0 and 40) that represent a portion
of the network in need of extensive rehabilitation such as full and partial reconstruction. Using sound
pavement management and finance principles, a very healthy network will have a backlog of 10% or less.
Tukwila met two out of three of the metrics for evaluating the quality of its roadway network.
✓ Tukwila's network average pavement condition score is slightly above the national average
currently seen by IMS of 60 to 65, with the City's average scoring a 65.6.
o The number of streets rated Excellent is below the minimum recommended target of 15% at 6%
✓ The backlog amount is below the average value of 12% at 1.3%.
BUDGET SCENARIOS
See section 5 for more information
The current annual budget for Tukwila is $1.05M per year dedicated to pavement preservation and
rehabilitation. This will grow the backlog to 12% while reducing the average PCI to a 59 over 5 years.
Please note this number is an annual budget average across all 5 years of the analysis horizon.
The PCI control budget of $1.22M per year and will maintain the network average PCI at a 60 while
increasing the backlog to 11%.
EXECUTIVE SUMMARY CONCLUSION
The Tukwila network has an average PCI of 65.6 and a backlog of 1.3%, with most of the network landing
in the Very Good PCI range. With the City's existing budget, the network conditions will degrade into the
high 50s PCI range and backlog will continue to grow over time. It is worth noting that the City does have
a fair amount of streets approaching the end of their lifespan where overlays can be effective,
representing a percentage of the network at the steepest part of their deterioration curves.

2.0 PRINCIPLES OF PAVEMENT MANAGEMENT
2.1 PAVEMENT PRESERVATION
Preservation of existing roads and street systems has become a major activity for all levels of
government. Because municipalities must consistently optimize the spending of their budgets, funds that
have been designated for pavement must be used as effectively as possible. The best method to obtain
the maximum value of available funds is through the use of a pavement management system.
Pavement management is the process of planning, budgeting, designing, evaluating, and rehabilitating a
pavement network to provide maximum benefit with available funds.
A pavement management system is a set of tools or methods that assist decision makers in finding
optimal strategies for providing and maintaining pavements in a serviceable condition over a given time
period. The intent is to identify the optimum level of long-term funding to sustain the network at a
predetermined level of service while incorporating local conditions and constraints.

Figure 2 — Pavement Deterioration and Life Cycle Costs
As shown as Figure 2, the streets that are repaired while in good condition will cost less over their lifetime
than those left to deteriorate to a poor condition. Without an adequate routine pavement maintenance
program, streets require more frequent reconstruction, thereby costing millions of extra dollars.
The key to a successful pavement management program is to develop a reasonably accurate
performance model of the roadway, and then identify the optimal timing and rehabilitation strategy. The
resultant benefit of this exercise is realized by the long term cost savings and increase in pavement
quality over time. As illustrated in Figure 2, pavements typically deteriorate rapidly once they hit a specific
threshold. A $1 investment after 40% lifespan is much more effective than deferring maintenance until
heavier overlays or possibly reconstruction are required just a few years later.
IMS Infrastructure Management Services Tukwila_Report Page 3
15
Once implemented, an effective pavement information management system can assist agencies in
developing long-term rehabilitation programs and budgets. The key is to develop policies and practices
that delay the inevitable total reconstruction for as long as practical yet still remain within the target zone
for cost effective rehabilitation. That is, as each roadway approaches the steepest part of its deterioration
curve, apply a remedy that extends the pavement life, at a minimum cost, thereby avoiding costly heavy
overlays and reconstruction. Figure 3 illustrates the concept of extending pavement life through the
application of timely rehabilitations.

Figure 3 — Pavement Life Cycle Curve
Ideally, the lower limit of the target zone shown in Figure 3 would have a minimum PCI value in the 60 to
70 range to keep as many streets as possible requiring a thin overlay or less. The upper limit would tend
to fall close to the higher end of the Very Good category — that is a pavement condition score
approaching 85. Other functions of a pavement management system include assessing the effectiveness
of maintenance activities, new technologies, and storing historical data and images.
For Tukwila, a prioritization methodology based on pavement condition, pavement materials, functional
class, and strength rating was used to analyze the network condition and develop the proposed 5 year
rehabilitation plan.
The analysis methodologies and data collection technologies were based on ASTM D6433 Standard
Practice for Roads and Parking Lots Pavement Condition Index Surveys (hereinafter ASTM D6433) for
assessment of pavement surface condition and the International Roughness Index (IRI) for quantification
of pavement roughness on all City streets. These measurements of pavement quality are combined to
form an overall 0 to 100 Pavement Condition Index (PCI), with 100 being the best.

2.2 ECONOMIC IMPACTS OF MAINTENANCE & REHABILITATION
The role of the street network as a factor in the City's well-being cannot be overstated. In the simplest of
terms, roadways form the economic backbone of a community. They provide the means for goods to be
exchanged, commerce to flourish, and commercial enterprises to generate revenue. As such, they are an
investment to be maintained.
The overall condition of an agency's infrastructure and transportation network is a key indicator of
economic prosperity. Roadway networks, in general, are one of the most important and dynamic sectors
in the global economy. They have a strong influence on not only the economic well-being of a community,
but a strong impact on quality of life. Well -maintained road networks experience multiple socioeconomic
benefits through greater labor market opportunities and decreasing income gap.
As a crucial link between producers and their markets, quality road networks ensure straightforward
access to goods and drive global and local economies. Likewise, higher network quality has a strong
correlation to improvements in household consumption and income. Roads also act as a key element to
social cohesion by acting as a median for integration of bordering regions. This social integration
promotes a decreased gap in income along with diversity and a greater sense of community that can play
a large role in decreasing rates of poverty.
Conversely, deterioration of roads can have adverse effects on a community and may bring about
important and unanticipated welfare effects that the governments should be aware of when cutting
transportation budgets. Poor road conditions increase fuel and tire consumption while shortening intervals
between vehicle repair and maintenance. In turn, these roads result in delayed or more expensive
deliveries for businesses and consumers. Economic effects of poor road networks, such as time
consuming and costly rehabilitation, can be reduced if a proactive maintenance approach is successfully
implemented. To accomplish this, a pavement assessment and analysis should be completed every few
years in an effort update the budget models and rehabilitation plans. As shown below, the IMS Laser
Road Surface Tester (featured in Figure 4) was mobilized to Tukwila to conduct an objective survey.

3.0 THE PAVEMENT MANAGEMENT PROCESS
3.1 FUNCTIONAL CLASS REVIEW
As part of the scope of this assignment, the functional classification designations currently used in the
Tukwila pavement management program were adopted for their use in the pavement analysis.
Although there is no uniform standard for classifying pavement into functional classes, The Federal
Highway Administration (FHWA), American Public Works Association (APWA) and Institute of
Transportation Engineers (ITE) offer some broad guidelines on how to assign classifications that were
followed in this study.
The City's functional classification definitions used in the assessment are as follows:
1. Principal Arterial (PART) — all cross City corridors consisting of 2 to 4 or more lanes, generally
spaced at 1 mile intervals with daily traffic counts generally exceeding 20,000 vehicles per day.
Major cross City corridors with a landscaped median were also assigned to Principal Arterials.
2. Minor Arterial (MnART) — Continuous and discontinuous cross city and inter -district corridors
that are 2 to 4 lanes across and generally have a centerline stripe or a designated bus route. The
ADT generally falls in the 10,000 to 20,000 vehicle per day range. They are typically spaced on
the 1/2 or mile section line and on occasion, may have a short non -landscaped median.
3. Collector (COL) — Continuous and discontinuous cross City and inter -district corridors that are 2
to 4 lanes across and generally have a centerline stripe or a designated bus route. The ADT
generally falls in the 1,000 to 10,000 vehicle per day range. They are typically spaced on the 1/2 or
1/4 mile section line and on occasion, may have a short non -landscaped median. Major collectors
are also assigned to streets segments leading to, or adjacent to, a major traffic generator site
such as a regional shopping complex. Collectors form the entrance to communities and may have
a decorative landscaped median of short duration.
4. Local (LOC) — These are the majority of the street segments consisting of all residential roads
not defined above or as industrial/commercial.
IMS Infrastructure Management Services Tukwila_Report Page 6

The paved roadway network consists of 4 functional classes, covering approximately 80.5 miles of
pavement. The average pavement condition index (PCI) of the roadway network is a 65.6 and the
network's primary pavement type is asphalt. The following table and Figure 5 summarize the functional
classification splits within the system.

As discussed later in this report, the functional classifications also play a critical role in the rehabilitation
candidate selection process as Arterials are generally given preference over other rehab candidates due
to their higher traffic counts and steeper deterioration curves.

3.2 ASSEMBLY OF DATA INTO PROJECTS
Tukwila's Geographic Information System (GIS) was used as the basis for segmenting the roadway
network on a block -by -block basis. Each segment was assigned a unique identifier referred to as a
GISID, establishing a one-to-one relationship between the GIS and the street inventory. The segments
form the basic building block of the pavement management system and are where all attribute and
condition data are stored.
The centerline segments were aggregated together within the pavement management system to form
logical projects that the analysis and rehabilitation program are developed against.
• Arterial projects run from major intersection to major intersection up to 1 mile in length.
• Similar to arterials, collector streets within a neighborhood were aggregated together to form a
single project where practical.
• Local streets along a homogenous route were aggregated together along with adjacent side
streets to form a small neighborhood based approach.
Segments were joined only when the pavement condition and functional classification were
homogeneous in nature such that when joined they have a relatively uniform condition that may be
rehabilitated using a single strategy.
The following figure (Figure 7) highlights the projects, used for the analysis. An electronic version of this
map is appended to this report.

Following a set of predefined assessment protocols matching the pavement management software
(ASTM D6433), a specialized piece of survey equipment — referred to as a Laser Road Surface Tester
(Laser RST, pictured on page 5) — is used to collect observations on the condition of the pavement
surface, as well as collect high definition digital imagery and spatial coordinate information. The Laser
RST surveys each local street from end to end in a single pass, while all other roadway classifications are
completed in two passes.
Key pavement condition data elements collected by the Laser RST include:
Surface Distress Index — The Laser RST collects surface distress observations based on the extent and
severity of distresses encountered along the length of the roadway following ASTM D6433 protocols for
asphalt and concrete pavements. The surface distress condition (cracking, potholes, raveling, and the
like) is considered by the traveling public to be the most important aspect in assessing the overall
pavement condition.
Presented on a 0 to 100 scale, the Surface Distress Index (SDI) is an aggregation of the observed
pavement defects. Within the SDI, not all distresses are weighted equally. Certain load associated
distresses (caused by traffic loading), such as rutting or alligator cracking on asphalt streets, or divided
slab on concrete streets, have a much higher impact on the surface distress index than non -load
associated distresses such as raveling or patching. Even at low extents and moderate severity — less
than 10% of the total area — load associated distresses can drop the SDI considerably. ASTM D6433 also
has algorithms within it to correct for multiple or overlapping distresses within a segment.
For this project, extent and severity observations were collected, processed, and loaded into the
pavement management software. Within the software, the following distresses, listed in order from
greatest to lowest impact, are presented as a 0 to 10 rating for review and reporting:
• Alligator Cracking — Alligator cracking is quantified by the severity of the failure and number of
square feet. Even at low extents, this can have a large impact on the condition score as this
distress represents a failure of the underlying base materials.
• Wheel Path Rutting — Starting at a minimum depth of '/4 inch, wheel path ruts are quantified by
their depth and the number of square feet encountered. Like alligator cracking, low densities of
rutting can have a large impact on the final condition score.
• Longitudinal, Transverse, Block (Map), and Edge Cracks — These are quantified by their length
and width. Longitudinal cracks that intertwine are the start of alligator cracking.
• Patching — Patching is quantified by the extent and quality of patches. When the majority of a
roadway surface is covered by a patch, such as a large utility replacement, the rating of the patch
is minimized. All potholes are rated as patches.
• Distortions — All uneven pavement surfaces, such as depressions, bumps, sags, swells, heaves,
and corrugations, are included as distortions and are quantified by the severity and extent of the
affected area.
• Raveling — Raveling is the loss of fine aggregate materials on the pavement surface and is
measured by the severity and number of square feet affected.
IMS Infrastructure Management Services Tukwila_Report Page 12
24
• Bleeding — Bleeding is the presence of free asphalt on the roadway surface caused by too much
asphalt in the pavement or insufficient voids in the matrix. The result is a pavement surface with
low skid resistance and is measured by the amount and severity of the area.
• Similar distresses were collected for concrete streets including divided slab, corner breaks, joint
spalling, faulting, polished aggregate, and scaling.
Roughness Index — Roughness is recorded following the industry standard "International Roughness
Index" (IRI), a measure of the change in elevation over a distance expressed as a slope and reported in
millimeters/meter. The IRI value is converted to a 0 to 100 score and reported as the Roughness Index
(RI) as follows:
RI = (11 — 3.5 x In(IRI)) x 10
In(IRI) is the natural logarithm of IRI.
In common terms, a newer street would generally have a Roughness Index above 85, while one due for
an overlay would be in the range 40 to 70. Failed streets typically have roughness values below 40.
Structural Index — The network of streets was not tested for structural adequacy, instead, the
relationship between the final pavement condition score and amount of load associated distresses was
analyzed and each pavement section assigned a Weak, Moderate or Strong strength rating. The
assigned structural index (30, 60 or 80 for weak, moderate and strong respectively) was not used in
determining the overall pavement condition score, but simply to classify the pavement strength and aid in
selecting appropriate rehabilitation strategies.
Pavement Condition Index (PCI) — Following our field surveys, the condition data is assembled to create
a single score representing the overall condition of the pavement. The Pavement Condition Index (PCI) is
calculated as follows:
PCI = 33% Roughness Index + 67% Surface Distress Index
Development of the pavement management plan and budgets were completed using Tukwila - specific
rehabilitation strategies, unit rates, priorities, and pavement performance curves. The process was
iterative in its attempt to obtain the greatest efficiency and cost benefit.

4.2 TUKWILA NETWORK CONDITION IMAGERY
The images presented below provide a sampling of the Tukwila streets that fall into the various condition
categories with a discussion of potential rehabilitation strategies.
Very Poor (PCI = 0 to 25) — Complete Reconstruction
62nd Avenue from 151st Street to South 151st Street (GISID 1004, PCI = 25) — Rated as Very Poor, this
street displays spreading base failure as evidenced by the severe alligator cracking and patching. It is
also worth noting that the patching along the left hand side of the street has severely deteriorated as
evident by the alligator cracking surrounding the patched areas. A mill and overlay on this street would
not be suitable as the base has failed and would not meet an extended service life of at least 15 years.
This street requires a full reconstruction and should be carefully monitored.
Deferral of reconstruction of streets rated as Very Poor will not cause a substantial decrease in pavement
quality as the streets have passed the opportunity for overlay -based strategies. Due to the high cost of
reconstruction, Very Poor streets are often deferred until full funding is available in favor of completing
more streets that can be rehabilitated at lower costs, resulting in a greater net benefit to the City. This
strategy however must be sensitive to citizen complaints forcing the street to be selected earlier. In
addition, this type of street can pose a safety hazard for motorists, since severe potholes and distortions
may develop. It is important to consistently monitor these streets and check for potholes or other
structural deficiencies until the street is eventually rebuilt.
IMS Infrastructure Management Services Tukwila_Report Page 15
27
Poor (PCI = 25 to 40) — Last Opportunity for Surface Base Rehabilitation
Boeing Access Road from Martin L King Jr Ramp to Martin L King Way (GISID 1975, PCI = 35) —
Rated as Poor, this segment still has some remaining life before it becomes a critical reconstruction need.
As evident in the imagery, most of the cracks have been properly sealed. On this street, the base is
showing signs of failure in areas exhibiting alligator/fatigue cracking. The severely cracked areas are
isolated and do not persist throughout the entire segment length and cross section. These areas should
be dug out and structurally patched to attain the maximum life from any potential rehabilitation efforts. If
left untreated, within a short period of time, a full reconstruction would be required.
On arterial roadways, Poor streets often require partial to full reconstruction — that is removal of the
pavement surface and base down to the subgrade and rebuilding from there. On local roadways, they
require removal of the pavement surface through grinding or excavation, base repairs, restoration of the
curb line and drainage, and then placement of a new surface.
In general, the service life of Poor streets is such that if deferred for too long, it would require a more
costly reconstruction. Streets rated as Poor are typically selected first for rehabilitation as they provide the
greatest cost/benefit to the City — that is the greatest increase in life per rehabilitation dollar spent.
IMS Infrastructure Management Services Tukwila_Report Page 16
28
Marginal (PCI = 40 to 50) — Progressively Thicker Overlays
Fun Center Way from East Interurban Avenue to South West Grady Way (GISID 1364, PCI = 48) —
Rated as marginal with a PCI score at the lower range between Marginal and Poor streets. Marginal
streets have distresses that tend to be localized and moderate in nature — that is they do not extend the
full length of the segment and can be readily dug out and repaired. This street segment highlights this
characteristic as the failed area does not quite extend the full length or width of the roadway and is still
serviceable. However, it also highlights the relationship between base and pavement quality. Placing an
overlay on this street without repairing the base would not achieve a full 15 year life as the failure would
continue to occur over time. Structural patching of the failed areas along localized rehabs would permit a
full width grind and inlay on this street segment and return it to full service. The curb lines are straight
and drainage is functioning well.
Marginal streets that display high amounts of load associated distresses are selected as a priority for
rehabilitation as they provide the greatest cost/benefit to the City. If left untreated, Marginal streets with
high amounts of load associated distresses would deteriorate to become partial reconstruction
candidates. Marginal streets that are failing due to materials issues or non -load associated failures may
become suitable candidates for thick overlays if deferred, without a significant cost increase.
IMS Infrastructure Management Services Tukwila_Report Page 17
29
Fair (PCI = 50 to 60) — Thin to Moderate Overlays
Interurban Avenue From Macadam Road to Gateway Drive (GISID 1998, PCI = 53) — Rated in the Fair
category, these streets require thin to moderate overlays for asphalt when they enter their need year
(generally within 2-3 points of the lower PCI in the defined range). Several distresses are present, but
tend to be more localized and moderate in severity, and non -load related (primarily longitudinal and
transverse cracking and raveling). On this segment of road, the signs of deterioration are evident in the
right hand travel lane of the pavement and are moderate in severity indicating the base has not yet failed
along the entire length of roadway. The curb line is straight through the sidewalk could benefit from some
preventative maintenance to prevent damage from weed intrusion.
Asphalt streets rated as Fair tend to receive a lower priority when developing a rehabilitation program. If
deferred, the rehabilitation cost would only increase by about $3 to $5/yd2, again depending on the
functional classification, in about 5 to 10 years. This delay represents a 20% difference over the time
stated. Thus, the cost of deferral is low when compared to deferring a thick overlay to a reconstruction
with a two to threefold increase in cost.
IMS Infrastructure Management Services Tukwila_Report Page 18
30
Good (PCI = 60 to 70) — Surface Treatments to Thin Overlays
Macadam Road from 149th Lane to 150th Street (GISID 2064, PCI = 62) — Rated as Good with the
primary cause of deterioration the transverse and longitudinal cracking, as well as patching. It also
displays small amounts of load associated distresses that can easily be removed to restore the visual
appearance of the roadway. The existing cracks should be sealed and the pavement surface restored,
with a heavier surface treatment such as microsurfacing or double slurry to fully waterproof the pavement
and cover the crack sealant. The occasional dig out and replacement may be required to correct
localized deficiencies. Alternatively, depending on the extent of the distressed areas, base strength and
drainage, a thin overlay may be applied.
Asphalt streets rated as Good are ideal candidates for thinner surface -based rehabilitations and local
repairs. Depending on the amount of localized failures, a thin edge mill and overlay, or possibly a surface
treatment, would be a suitable rehabilitation strategy for streets rated as Good. Streets that fall in the high
60 - low 70 PCI range provide the greatest opportunity for extending
pavement life at the lowest possible cost, thus applying the principles
of the perpetual life cycle approach to pavement maintenance. The
adjacent photo is a great example of a street segment (not a Tukwila
Road) that displayed low load associated distresses and thus, high
structural characteristics, and once the distressed areas were
replaced, a slurry seal was applied. The patching accounted for less
than 5 to 10% of the total area and resulted in a good looking,
watertight final surface at a much lower cost than an overlay with less
disruption to the neighborhood and curb line. The patches were
paver laid and roller compacted.
IMS Infrastructure Management Services Tukwila_Report Page 19
31
Very Good (PCI = 70 to 85) — Surface Treatments and Localized Rehabilitation
West Valley Highway from Strander Boulevard to 180th Street (GISID 1293, PCI = 73) — Rated as
Very Good, this road displays minor amounts of transverse cracking and patching. The surface is non -
weathered, and the base is still strong. This street is an example of a candidate for preventative
maintenance and light weight surface treatments to extend the life of a roadway.
Asphalt streets rated as Very Good generally need lightweight surface -based treatments such as surface
seals, slurries, chip seals or microsurfacing. Routine maintenance such as crack sealing and localized
repairs often precede surface treatments. The concept is to keep the cracks as waterproof as possible
through crack sealing and the application of a surface treatment. By keeping water out of the base layers,
the pavement life is extended without the need for thicker rehabilitations such as overlays or
reconstruction. Surface treatments also tend to increase surface friction and visual appearance of the
pavement surface but do not add structure or increase smoothness.
Surface treatments may include:
• Double or single application of slurry seals (slurries are a sand and asphalt cement mix).
• Microsurfacing — asphalt cement and up to 3/8 sand aggregate.
• Chip seals and cape seals (Chip seal followed by a slurry).
Additional cost benefits of early intervention include:
• Less use of non-renewable resources through thinner rehabilitation strategies.
• Less intrusive rehabilitation and easier to maintain access during construction.
• Easier to maintain existing drainage patterns.
IMS Infrastructure Management Services Tukwila_Report Page 20
32
Excellent (PCI = 85 to 100)
Southcenter Parkway (GISID 1343, PCI = 93) — Rated as Excellent, displaying little to no surface
distresses. The ride is smooth and the surface is non -weathered and the base is strong. In a couple of
years, this street segment would be an ideal candidate for routine maintenance activities such as crack
sealant rehabilitation.
In terms of pavement management efficiency, a program based on worst -first, that is starting at the lowest
rated street and working up towards the highest, does not achieve optimal expenditure of money.
Generally, under this scenario, agencies can not sufficiently fund pavement rehabilitation and lose ground
despite injecting large amounts of capital into the network.
The preferred basis of rehabilitation candidate selection is to examine the cost of deferral of a street,
against increased life expectancy.
IMS Infrastructure Management Services Tukwila_Report Page 21

4.3 EVALUATING THE PAVEMENT QUALITY AND BACKLOG
The concept of the Pavement Condition Index (PCI) score, backlog percentage and number of streets
rated as Excellent must be fully understood in order to understand and develop an effective pavement
management program. These three metrics should fall into certain ranges in order to measure the quality
and long term viability of a network.
The PCI score indicates the overall pavement condition and represents the amount of equity in the
system; it is the value most commonly considered when gauging the overall quality of a roadway network.
It may also be used to define a desired level of service: that is, an agency may wish to develop a
pavement management program such that in five years the overall network score meets a set minimum
value. Obviously, the higher the PCI score the better off the overall network condition is. Agencies with
an average PCI score above 80 (when considering surface distress, roughness and possibly strength) are
rare and found only in a few select communities. Less than 1 in 20 communities surveyed by IMS have
that high of a condition average. Averages between 65 and 80 are indicative of either newer networks, or
ones that have an ongoing pavement rehabilitation program and tend to be fully funded. Scores between
60 and 65 are common and represent a reasonable average providing a satisfactory balance between
levels of service and funding, and when taken with the other two metrics may represent a well -managed
and funded network. A minimum score of 60 means that overall the network falls at the lower end of the
range where light weight surface treatments and thin overlays are the standard rehabilitation practice.
Below a 60 means an agency has to rely on more costly rehabilitations and reconstructions to address
condition issues.
At the upper end of the condition scale, a minimum of 15% of the network should be rated as Excellent.
Generally, at or above 15%, means that a noticeable percentage of the roadway network is in like new
condition, requiring only routine maintenance. While higher percentages of streets rated as Excellent are
certainly desirable, the annual cost to maintain rates at higher multiples is often cost prohibitive. Below
15% means the agency is struggling to effectively rehabilitate their network on an annual basis. The 15%
marker represents a cost effective balance between annual investment and satisfactory level of service.
Backlog roadways are those that have dropped sufficiently in quality to the point where surface based
rehabilitation efforts would no longer prove to be cost effective. These roadways are rated Poor or Very
Poor and will require either partial or total reconstruction. Backlog is expressed as the percentage of
roads requiring reconstruction as compared to the network totals.
It is the backlog, however, that defines the amount of legacy work an agency is facing and is willing to
accept in the future. It is the combination of the three metrics that presents the true picture of the
condition of a roadway network, and conversely defines improvement goals.
Generally, a backlog of 10% to 15% of the overall network is considered manageable from a funding point
of view with 12% being a realistic target. Fifteen percent (15%) is used as a control limit to indicate the
maximum amount of backlog that can be readily managed. Backlog rates below 10%, again are certainly
desirable, but financially unachievable for a large percentage of agencies. Backlogs approaching 20% or
more tend to become unmanageable, unless aggressively checked through larger rehabilitation
programs, and will grow at an alarming rate. At 20% a tipping point has been met and the backlog tends
to increase faster than an agency's ability to reconstruct their streets.

4.4 TUKWILA NETWORK CONDITION DISTRIBUTION
Figure 9 presented below shows the distribution of pavement condition for the roadway network in
Tukwila. The average PCI for the network is 65.6. While direct comparisons to other agencies are difficult
due to variances in ratings systems, Tukwila is slightly above average when compared to other agencies
recently surveyed by IMS, which typically fall in the 60 to 65 range.

• This is reflective of a moderately aged network that has had some roadway renewal effort.
• Simultaneously, the City has a moderate sample of streets that are approaching the end of their
life where surface based rehabilitations, such as overlays, can be effective.
• Traditionally we expect to see a bell curve that is skewed to the right and centered between a PCI
of 60 and 70. The Tukwila network curve illustrated above follows this norm and shows the
positive impact of recent roadway renewal effort over the last several years.

untreated, they will decline rapidly into reconstruction candidates.

roadways have failed or are past their optimal due point for overlay or surface -based
rehabilitation and may require progressively heavier or thicker forms of rehabilitation (such as

reconstruction.

4.6 STRUCTURAL AND LOAD ASSOCIATED DISTRESS ANALYSIS
Structural testing and analysis was not performed for the City of Tukwila. Instead, analysis of the cause
of pavement failure for these street segments was completed by examining the types of distresses that
have caused the PCI score to drop.
Surface distresses may be categorized into two classifications — load associated distresses (LADD) and
non -load associated distresses (NLAD). Load associated distresses are those that are directly related to
traffic loading and structural capacity. Non -load associated distresses are those that result from materials
or environmental issues including shrinkage (transverse) cracking, bleeding and raveling. Generally, load
associated distresses affect the overall condition score more than non -load associated distresses — as is
the case in Tukwila. For asphalt streets, roadways were classified as Weak, Moderate, or Strong.
The purpose of the structural analysis is twofold:
• The structural analysis provides input into which performance curve each segment is to use —
performance curves are used to predict pavement deterioration over time.
• Structural analysis assists in rehabilitation selection by constraining inadequate pavement
sections from receiving too light of a rehabilitation and conversely, identifying segments suitable
for lighter weight treatment.
Figure 14 plots the relationship of the load associated distresses (shown in red) against pavement
condition. As can be seen from the plot, at higher PCI scores, most pavements fall into the moderate
strength classification as the distresses have not yet begun to manifest themselves into severe failures.
As the PCI score drops, the load associated distresses typically affect the PCI score to a higher degree
with more segments being classified as weak. Conversely, segments that have a declining PCI score
and low LADD, are classified as strong as they display few load associated failures. High PCI score
(above 60) rehab selections should focus on pavement preservation activities such as surface treatments
or thin overlays, possibly with some localized pavement repairs and crack sealing.
The sum of the Load -Associated Distress deducts (LADD) is also used to qualify the appropriate
rehabilitation strategy selection in addition to the overall pavement condition score. For example, a street
that has a good PCI score (that is between 60 and 70) and is displaying relatively low load associated
distress deducts would be a suitable candidate for a surface treatment in place of a thin overlay in that the
PCI score is more influenced by materials issues such as transverse cracking or raveling.
Overall, the low amounts of streets exhibiting weak performance can generally be attributed to poor
subgrade conditions, insufficient pavement thickness and increased traffic loading — in particular heavy,
side -loading garbage and recycling trucks (an unintended consequence of green initiatives) along with
school buses and delivery vehicles. The average weight of these vehicles coupled with tire pressure and
configuration today compared to those from a few decades ago has increased drastically.

• The upper black diagonal line identifies segments that have a high ratio of load associated
distresses compared to their PCI score. These segments are classified as weak.
• The lower black diagonal line identifies segments that have a low ratio of load associated
distresses compared to their PCI score and are classified as strong.
• Segments that fall between the two lines are assigned a moderate pavement strength.
The sum of the Load -Associated Distress deducts (LADD) is also used to qualify the appropriate
rehabilitation strategy selection in addition to the overall pavement condition score.

5.0 REHABILITATION PLAN AND BUDGET DEVELOPMENT
5.1 KEY ANALYSIS SET POINTS AND PAVEMENT PERFORMANCE CURVES
Pavement management analysis requires user inputs in order to complete its condition forecasting and
prioritization. A series of operating parameters were developed in order to create an efficient program
that is tailored to the City's needs.
Some of the highlights include:
• The pavement performance curves that are used to predict future pavement condition. Asphalt
streets are classified as weak, moderate, or strong, and then assigned the appropriate pavement
performance curve based on their functional classification to use in the analysis. The concept of
load associated distresses does not apply to concrete streets.
• The shape of performance curves reflect the concept of deferred maintenance and salvage life.
Instead of dropping to an absolute PCI value of 0 after 40 years of service, the curves are
designed to become asymptotic to the age axis and have a whole life of approximately 50 to 60
years depending on pavement type. This indicates the notion that once a street deteriorates past
a specific threshold — about a PCI of 20, age becomes less important in rehab selection.
• Priority ranking analysis uses prioritization for rehabilitation candidate selection. It is designed to
capture as many segments in their need year based on the incremental cost of deferral. The
higher the functional classification of a street, the higher priority a segment is given.
Rehabilitation Strategies and Unit Rates
The rehab strategies and unit rates used in the pavement analysis can be found on the following page.
Some important parameters include:
• Rehab Code and Activity — The assigned identifier and name to each rehabilitation strategy.
The term "RR" refers to "Remove and Replace", otherwise known as Structural Patching. When
this term is present, additional funds have been assigned to the strategy to allow for an increased
amount of preparation work and patching. The relative terms of thin, moderate and thick are
used to describe the overlay thickness. This is to facilitate consistency in the naming convention,
but does not imply the same material thickness has to be used for each functional classification.
The recommended rehab activities for any given PCI range may vary due to pavement strength
and functional classification. For example, an arterial between a PCI of 50 to 60 may receive a
thin to moderate overlay, while a local access road may only receive a chip seal or thin overlay.
• Unit Rates — The rehab costs are presented on a per square yard basis for each pavement type,
functional class, and rehabilitation activity combination. The rates were developed using typical
national averages for similar activities and adjusted for Tukwila's location and unique conditions.
An additional burden to all costs was also added to cover City overheads, design and engineering
and inspection. Costs for peripheral concrete rehab (valley gutters, inlets, approaches, etc.) have
not been included in the analysis.

The unit rates are reflected in the network value, final budgets, and average cost/mile for doing
work in Tukwila.

Figure 15 - Rehab rates by Functional Class
*Unit rates vary slightly between functional classes
Min PCI, Critical PCI, and Max PCI - These define the Pavement Condition Index (PCI) range
applicable to the rehab selection. The Critical PCI defines when a segment is in its need year and is
deemed to be critical, otherwise if deferred, the street declines in PCI past the point which the
rehabilitation is no longer appropriate. Generally the Critical PCI falls 2 to 4 points higher than the
minimum PCI applicable for each rehab activity.

Figure 16 graphically presents the application of pavement rehabilitations for asphalt streets by PCI. The
Rehab numbers are simply placeholders that separate each rehabilitation project identified on the chart
above. For example, Rehab 56 is a Thick Overlay + Structural Patch.
Unit rates increase slightly between functional classes to reflect increase costs in pavement thickness,

Figure 16 — Asphalt (ACP) Rehabilitation Strategies
Selection and Prioritization of Rehab Candidates
80 90 100
The City's pavement management program incorporates a series of user defined values to prioritize and
select the street segments for rehabilitation. The rehab selection order is not worst first, but rather
designed to capture as many segments in their need year based on the incremental cost of rehab
deferral. A Street is considered to be in its need year when it has reached its maximum service life and
any further deferral would require a heavier and more costly rehabilitation. The rehab program has been
designed to maximize the increased service life for each rehabilitation dollar spent on a segment.
Other factors included in the prioritization process focus on:
• Need Year — streets are only selected when they have expended their service life and are optimal
for rehab selection.
IMS Infrastructure Management Services Tukwila_Report Page 32
44
• Functional Classification — generally priority is given to higher functional classifications as they
provide greater benefits to a larger group of users
• Pavement Strength — weaker streets are prioritized higher than stronger ones as they
deteriorate faster.
• Area — a very slight increase in priority is given to larger projects over smaller ones.
The net result is a program that favors thick overlays, followed by partial reconstruction projects then full
reconstruction projects (more for safety reasons than cost -benefit). These are then followed by surface
treatments and lastly by moderate to thin overlays.
The programmed deterioration curves illustrated in Figure 17 are designed to integrate the pavement
condition distribution performance curves for the network, with the applied rehabilitation strategies and
their expected life cycle. Different color performance curves are meant to represent the full suite of curves
assigned to segments based upon their functional class, pavement type, and strength.
It is important to recognize that even though all streets fall into specific rating categories and their
respective rehabilitation strategies, it is not until a street falls to within a few points of the lower end of the
range that it will become a critical need selected for rehabilitation.

5.2 FIX ALL AND ANNUAL ESTIMATES
Three different approaches may be taken to identify and confirm the amount of funds the City needs to
set aside each year to maintain the roadway network at its current condition. All three are completed
externally to the pavement management system and are simply used to validate the final results.
Option 1 — Estimated Life Cycle Cost Based on Network Value
An approximate value for the annual street maintenance budget may be quickly determined by taking the
total value of Tukwila's roadway network, estimated at $145M, and dividing that by the ultimate life of a
roadway — approximated to be 50 years. By this method, the annual budget is estimated at $2,900,000.
Please note, the 50 year lifespan of the roadway is the theoretical life of the roadway surface from
construction, until the point at which there not usable surface remaining, it is not simply the lifespan of the
pavement surface until the next overlay.
Rehabilitation Estimate Based on Network Valuation

Asphalt Network 145,009,000 50 2,900,000
City of Tukwila, WA Network Totals:
145,009,000 2,900,000
Option 2 — Estimated Life Cycle Cost Based on Current Condition
A second method to validate the annual budget is to identify the average network PCI and associated
rehabilitation requirements, and then estimate the number of miles required to be rehabilitated each year
based on a typical life cycle for that rehabilitation activity. For Tukwila, the average PCI for asphalt roads
is 66, which places the Tukwila asphalt network in the Edge Mill + Thin Overlay, at an average cost of
$23.55/yd2. Based on this estimate the City needs to spend approximately $2,107,337/year to maintain
the current condition average.

Option 3 - Estimated Life Cycle Cost Based on Network Deficiency
The third methodology to confirm the required amount of annual funding is to identify the current network
deficiency, that is the amount required to rehabilitate all streets in the network assuming unlimited
funding, and then divide by the typical life cycle of each rehabilitation activity. This is referred to as the
Fix All Estimate and Life Cycle Cost. The rehab strategies listed in the table are generic in nature and not
necessarily the final set that was applied to Tukwila. For Tukwila, the Fix All Estimate for the network
deficiency is approximately $34M and the Life Cycle Cost is $1.97M/year, broken down as follows:

5.3 NETWORK BUDGET ANALYSIS MODELS
An analysis containing a total of 10 profile budget runs plus a Do Nothing options was prepared for
Tukwila.
The analysis results are summarized below:
• Do Nothing (illustrated in Figure 20) — This option identifies the effect of spending no capital for 5
years. After 5 years, this scenario results in a network average PCI drop from a 66 to a 54 and a
dramatic increase in backlog to 17%
• Client Budget (Green Line) — this represents the City's current annual budget of $1.05M annually
dedicated to pavement preservation and rehabilitation. This level of funding will result in a
network average PCI score of 59 and a backlog increase to 12%.
• Steady State PCI — this is simply the funds required to maintain the current network average PCI
at a 66. The annual budget required to do so is on the order of $2.42M annually, however
backlog (Very Poor & Poor roadways) continues to climb to 6%.
• Backlog Control Budget — A budget designed to maintain the City's current backlog at 5%.
The results of the analysis are summarized in Figure 18 below. The X-axis highlights the annual budget,
while the Y-axis plots the 5 Year Post Rehab Network Average PCI value. The diagonal blue line is the
results of the pavement analysis (the Tukwila model profile).

5.5 TRUE COST OF UNDERFUNDING OF A ROADWAY NETWORK
Funding of roadway rehabilitation is an exercise in identifying the balance between available funding and
the desired level of service that is right for each agency. There are no hard rules for what is the definitive
level of funding as this is a decision for local elected officials, based on their priorities and practices.
However, the true costs of over and underfunding must be presented in order to provide decision makers
with all the information available to base the decisions upon. Tukwila has a considerable investment in
their paved roadway network with a combined replacement value (just for the streets, not right of way)
exceeding $36M. Spreading this cost over a 50 year period (the expected ultimate life of a roadway)
means that an annual investment on the order of $2.42M per year would be required — not including the
cost of maintenance, deterioration ,repair curbing, drainage, tree roots, sidewalks or ADA ramps.
Government Accounting Standards Board Statement 34 requires that agencies who collect taxes (local,
business, property or gas taxes) for the purpose of maintaining long term infrastructure assets (such as
roads) be good stewards of those assets by either accounting for them financially on the City's balance
sheet, or implement a methodology to manage and fund them to a locally defined level of service.
The condition of a roadway network may be equated to equity in a depreciating asset. Regular payments
to that asset must be made in order to maintain the equity at a constant level. Should those payments fall
short, the equity must eventually be replaced through a large influx of capital in order to make the
investment whole again. Roadway networks are no different. Long term underfunding of rehabilitation
and maintenance is the direct equivalent of removing equity from an asset — eventually it must be repaid
through total reconstruction. The following table compares the real cost of the various budgets against
the Do Nothing and Steady State options.

5.6 NETWORK RECOMMENDATIONS AND COMMENTS
The following recommendations are presented to Tukwila as an output from the pavement analysis, and
must be read in conjunction with the attached reports.
1. Tukwila should adopt a policy statement to maintain PCI at or above a 60 while keeping backlog
below 15%.
An annual budget of $1.05M (dedicated to pavement rehabilitation) will achieve a network
average PCI of 59 and backlog of 12%.
An annual budget of $2.42M (dedicated to pavement rehabilitation) will achieve a network
average PCI of 66 and backlog of 6%.
2. The full suite of proposed rehabilitation strategies and unit rates should be reviewed annually as
these can have considerable effects on the final program.
3. No allowance has been made for network growth. As the City expands or increases the amount of
paved roads, increased budgets will be required.
4. No allowance has been made for routine maintenance activities such as asphalt crack sealing,
pothole filling, sweeping, striping or patching within the budget runs and analysis. These costs are
assumed to be outside the pavement management costs.
5. The City should resurvey their streets every few years to update the condition data and
rehabilitation program.
