REPORT-IN-BRIEF
Following the City of San Luis Obispo's (City) Pavement Management Plan (PMP), staff
recommends advertisement of the 2026 Roadway Sealing Project (“Project”) to provide
maintenance and striping improvements to the streets shown in Attachment A.
Pavement maintenance projects often involve complete removal and replacement of
roadway striping and pavement markings, which provides excellent opportunities to
incorporate planned safety and complete street improvements as part of these larger
Page 255 of 412
Item 7b
roadway maintenance efforts. The 2026 Roadway Sealing Project will implement several
street modifications from the City’s adopted Active Transportation Plan (ATP) to improve
safety and mobility for all road users. These strategies include design elements intended
to improve pedestrian crossing safety, increase separation between bicyclists and motor
vehicle traffic, and measures to calm traffic and reduce speeds on certain streets.
This Project will be funded in Fiscal Year 2026 -27. Allocated funds per the
recommendations of this staff report are anticipated to be sufficient for this project. The
Project will be advertised during the late spring, and construction is planned to begin in
the late summer.
POLICY CONTEXT
On May 17, 2022, Council approved a Purchasing Policy Update to the Financial
Management Manual that required Council approval for Public Projects that cost over
$200,000.
Implementation of the Project aligns directly with several City plans, policies and goals,
including the application of various elements identified in the City’s 2021 Active
Transportation Plan (ATP) aimed at improving walking and bicycling infrastructure, as
well as transportation safety improvements identified in the City’s Draft Vision Zero Action
Plan1. Additionally, the project contributes to the Major City Goal of Infrastructure and
Sustainable Transportation. The project also supports the ongoing maintenance of City
streets as outlined in the Pavement Management Plan.
DISCUSSION
Background
The 2026 Roadway Sealing Project (the “Project”) continues implementation of the City’s
Pavement Management Plan, an ongoing effort to maintain and extend the useful life of
the City’s roadways. The Pavement Management Plan, originally adopted in 1998,
establishes nine zones (“Pavement Management Areas”) within the City. The City’s
annual sealing projects typically alternate between roadway sealing on local and collector
streets within two Pavement Management Areas in one year and then focusing on arterial
street work in the second year, thereby alternating between neighborhood areas and
arterials biennially to maintain the over 140 miles of City-owned roadways in a state of
good repair.
This year’s pavement maintenance project will focus on slurry sealing local streets in
Pavement Management Areas 2 and 3. The Project also includes pavement maintenance
and restriping on other roadways that were either (a) scheduled previously, but deferred
due to construction conflicts, or (b) collector or arterials streets not scheduled for
pavement maintenance, but with road markings that are badly faded and in need of
restriping. The Additive Alternative A of the project includes only the following:
1 The Vision Zero Action Plan is currently in draft form and scheduled for final review and
potential adoption by the City Council on May 19, 2026. Visit the City’s Traffic Safety (Vision
Zero) Website for more information on the Action Plan and traffic safety data.
Page 256 of 412
Item 7b
1. Slurry seal on South Broad Street from Tank Farm Road to Farmhouse Lane
2. New thermoplastic striping with no change to the current striping configuration.
The project plans and special provisions are structured with a Base Bid and one Bid
Additive Alternative A to maximize the scope of work that can be completed within
available funding. The strategy is to award the construction contract with the Base Bid
and Additive Alternative A as funding will all ow, up to the Publicly Disclosed Funding
amount of $3,932,000 in compliance with Public Contract Code Section 20103.8(c). If the
lowest responsive total bid is in excess of the Publicly Disclosed Funding Amount but the
Base Bid is within the funding amount, then the Base Bid will be recommended for award
without the Additive Alternative. Figure 1 below illustrates the streets included in the 2026
Roadway Sealing Project, while a larger-size map is provided as Attachment A.
Figure 1: 2026 Roadway Sealing Project Map
Design Details
While the Project is focused on prioritizing essential maintenance by slurry sealing and
restriping select streets, staff has incorporated additional design elements where feasible
Page 257 of 412
Item 7b
and as funding allows to advance the City’s traffic safety, active transportation, and
neighborhood traffic management goals. These additional design elements are
summarized further below.
All Streets
All streets within the Project limits will incorporate elements such as the addition of high
visibility “ladder style” crosswalk markings at all existing and newly proposed pedestrian
crosswalks. The project will also add red curb paint and/or “NO PARKING” signage to
“daylight” crosswalks, with a focus on priority intersections near schools and parks, along
arterial and collector streets, on designated neighborhood greenways, and in areas with
high pedestrian activity. In addition, all existing traffic calming features that currently exist
within the project limits will be retained.
Mill Street Neighborhood Greenway
Mill Street is identified in the ATP as a Tier 1 (highest priority) project, with a
recommendation to establish a neighborhood greenway from Chorro Street to Grand
Avenue. There will be no impacts to existing parking. This greenway will improve walking
and bicycling access between downtown, the North Chorro Greenway, the Morro (Bill
Roalman) Greenway, the Railroad Safety Trail, and Cal Poly. A portion of this greenway
was implemented on Mill Street between Pepper Street and Grand Avenue as part of the
2024 Sealing Project. The 2026 Roadway Sealing Project will complete the remaining
segment between Chorro and Pepper Streets, and include the following improvements:
Greenway guide signage and pavement markings
Pedestrian crossing warning signage, striped corner bulbouts, and daylighting at
Mill/Morro intersection
Striping refinements at the intersection of Mill Street and Santa Rosa Street to
improve turning maneuverability for SLO Transit buses
Additional on-street ADA parking stalls
Installation of an all-way stop at the intersection of Mill Street and Toro Street,
replacing the existing pilot neighborhood traffic circle (see more discussion below)
Installation of speed cushions to reduce vehicle speeds (see below for further
discussion)
Figure 2: Example Images of Neighborhood Greenway Markings
and Guide Signs
Page 258 of 412
Item 7b
Mill Street and Toro Street Intersection Configuration
A temporary neighborhood traffic circle was installed as a pilot project at the intersection
of Mill Street and Toro Street (see Figure 3 below) using temporary materials in late 2024
to address safety concerns reported by th e community. Prior to installation, there were
two reported crashes at this intersection in the past 10 years. In addition, frequent close
calls had been reported and confirmed via in-person observations by staff, typically
involving drivers on Toro Street (who have a stop sign) failing to yield right-of-way to Mill
Street traffic and pedestrians. Since installation of the circle, there have been no reported
crashes and no significant impacts to transit or emergency vehicle access . Staff have,
however, received feedback from community members expressing the following
concerns:
a) Unattractive aesthetics of the temporary materials
b) Continued pattern of illegal turns and right-of-way violations, despite the traffic
circle.
While traffic circles have effectively reduced speeding and conflicts at other intersections
in the city, staff are proposing to replace the pilot traffic circle at this location with all‑way
stop control and high‑visibility crosswalk markings. This recommendation is based on
current observations, analysis of traffic conditions, public input, and consideration of
aesthetics within the Mill Street Historic District. Although the intersection does not meet
all‑way stop warrants based solely on traffic volumes or collision history, the level of
pedestrian and bicycle activity across Mill Street combined with documented close calls
and observed user behavior provides adequate engineering justification consistent with
the California Manual on Uniform Traffic Control Devices . This recommendation reflects
the application of engineering judgment in a context with high multimodal activity and is
not intended to establish a blanket precedent for locations that do not present similar
conditions. This proposal is also aligned with the recommendations of the City’s Active
Transportation Committee and most public comments received on this topic. (See
Figure 3: Existing Neighborhood Traffic Circle at Mill/Toro to be Replaced with All-Way Stop
Control
Page 259 of 412
Item 7b
“Previous Advisory Body Approval” section later in this report for further discussion on
ATC input).
Mill Street Speed Cushions
In addition to the elements described above on Mill Street, staff recommends installation
of speed cushions to address speeding concerns and improve comfort for people driving,
walking, and bicycling. While existing traffic volumes on Mill Street are suitable for a
low‑stress shared street environment, prevailing vehicle speeds range from 25 -30 mph,
exceeding the City’s General Plan and ATP targets for a residential collector serving as
a neighborhood greenway (20-25 mph).
Speed cushions are similar to speed humps or tables but include wheel cutouts that
reduce impacts to fire trucks, ambulances, and buses, making them appropriate for
streets like Mill that serve as primary emergency response and transit routes. Staff
propose installing the cushions using pre‑formed rubber bolt‑down materials, which will
provide consistent control of the cushion shape and configuration while allowing
adjustments based on performance and feedback from emergency services and transit
providers. These speed cushions will be installed under a separate contract after sealing
is complete to allow greater flexibility in scheduling and refinement as needed. Because
these elements are not included in the current bid package, the proposed locations of
these speed cushions are shown on a separate exhibit shown in Attachment D.
Figure 4: Example Image of Speed Cushions
Page 260 of 412
Item 7b
Johnson Avenue
Johnson Avenue between Buchon Street and Bishop Street is identified in the ATP as a
Tier 2 (medium priority) active transportation corridor, with long term plans to implement
protected bike lanes. The ATP notes, however, that achieving this may require roadway
widening or removal of existing auto travel lanes, requiring further feasibility analysis.
During early planning for the 2026 Roadway Sealing Project, staff evaluated whether
protected bike lanes could be incorporated on Johnson Avenue, or whether buffered bike
lanes could be added as an interim step to increase separation from traffic and support
future protected facilities if current project funding cannot accommodate them. While a
few short segments, such as the block between Buchon Street and San Luis Drive , have
adequate width for buffered bike lanes, most of the corridor does not have sufficient right
of way to provide buffered or protected lanes without widening the roadway or removing
one or more existing travel lanes. Staff also note that some residents have advocated for
a road diet on Johnson Avenue for reasons beyond bicycle improvements, including a
desire to accommodate on-street parking, bus loading, commercial deliveries, or to calm
traffic and improve overall roadway safety.
Because widening Johnson Avenue is not feasib le at this time, staff prepared a traffic
operations analysis to evaluate whether lane removal (a “road diet”) could be a viable
option to reallocate roadway width. This preliminary analysis assessed auto Level of
Service (LOS) and projected vehicle queueing to compare the following scenarios:
1. Existing Road Configuration
2. Full Road Diet (Remove one travel lane in both the northbound and southbound
directions)
3. Partial Road Diet (Remove one northbound travel lane only)
4. Partial Road Diet (Remove one southbound travel lane only)
Analysis details and findings are documented in the Johnson Avenue Traffic Operations
Analysis Memo (Attachment B).
Based on current traffic analysis, all road diet scenarios are projected to increase
congestion, with LOS and vehicle queueing that would not meet the City’s adopted
performance standards. Under each scenario, one or more key intersections along
Johnson Avenue are expected to operate below the City’s minimum LOS standard of D,
with some approaches potentially experiencing LOS F conditions, resulting in increased
delays and queueing.
While these findings do not support implementation of a road diet at this time, the concept
could be revisited in the future as part of a more comprehensive corridor study that
evaluates updated traffic conditions, potential intersection improvements, and broader
multimodal design options.
Furthermore, the San Luis Obispo Fire Department has expressed concerns regarding a
road diet on this portion of Johnson Avenue, citing the potential for impacts to emergency
Page 261 of 412
Item 7b
response, particularly for access to French Hospital Medical Center. The corridor’s
function as an evacuation route further limits the feasibility of reducing vehicle capacity.
For all these reasons provided above, staff are not recommending implementation of a
road diet on this segment of Johnson Avenue at this time.
Note that staff’s recommendations differ from those of the Active Transportation
Committee, which is discussed later in this report. This conclusion does not preclude
revisiting bicycle facility improvements on Johnson Avenue in the future as part of a larger
capital project. Potential options may include roadway widening or pairing a road diet with
capacity improvements at intersection bottlenecks, such as converting signals to
roundabouts. Advancing the planned Flora-Fixilini Neighborhood Greenway as a future
capital project may also provide an alternative low-stress route for improving pedestrian
and bicycle access parallel to Johnson Avenue. These potential options would require
significant financial investment and are not currently incorporated into the City’s 10 -year
Capital Improvement Plan; future inclusion as part of the Financial Planning process could
require deferring or modifying planned programs and projects.
While roadway reconfiguration is not recommended currently, staff are proposing
incremental improvements as part of the 2026 Roadway Sealing Project, including:
1. Buffered bike lanes at limited locations where width allows
2. High-visibility crosswalks
3. Green bike lane conflict markings and enhanced warning signage to increase
visibility of pedestrians and cyclists
4. Installation of radar speed feedback signs in both directions to reduce vehicle
speeds.
Staff recommends that any future consideration of a road diet on Johnson Avenue include
additional analysis using updated traffic data, evaluation of future year traffic operations,
and more detailed assessment of potential impacts to emergency response and
evacuation. See the Alternatives section at the end of this report for further discussion of
next steps if the Council prefers to support the ATC’s recommendation to continue
exploring a road diet on Johnson Avenue.
Orcutt Road
Orcutt Road between Broad Street and Laurel Lane is identified in the City’s Active
Transportation Plan as a Tier 2 (medium‑priority) corridor with long‑term plans to
implement protected bike lanes. Although Orcutt Road is not scheduled for slurry sealing
as part of the 2026 Roadway Sealing Project, it will be restriped with the following
elements:
1. Add high-visibility crosswalk markings
2. Install striped bike lane buffers, and slight reduction in vehicle traffic lane widths to
reduce illegal speeds
3. Green bike lane markings through conflicts at intersections and driveways
4. Addition of a bicycle left turn box at westbound Orcutt approaching Broad Street
Page 262 of 412
Item 7b
5. Striping improvements near the Orcutt at-grade UPRR rail crossing as requested
by Union Pacific Railroad (UPRR)
6. Installation of rubber median curbs between Sacramento Drive and the existing
raised concrete median near the UPRR tracks (requested by UPRR to reduce
illegal mid-block crossings). A permanent landscaped median extension could be
recommended as a future project.
San Luis Drive
San Luis Drive between Johnson Avenue and California Boulevard is identified in the
City’s Active Transportation Plan as a Tier 3 (lower-priority) corridor with long-term plans
to install protected bike lanes and intersection control improvements. Implementing
protected facilities would require removal of on-street parking on at least one side of the
street, which would necessitate a more comprehensive public outreach process involving
San Luis Obispo High School representatives, students and families, and nearby
residents. The current scope and funding for the 2026 Roadway Sealing Project does not
support installation and maintenance of vertical bikeway elements or other higher -cost
improvements. Proposed improvements include:
1. Install high-visibility crosswalks and additional school crossing warning signage
2. Narrowing of vehicle travel lane widths with the addition of striped bike lane buffers
3. Installation of a few flex posts along the southbound bike lane approaching
Johnson Avenue to discourage illegal parking near the high school entrance
4. Add a southbound bicycle box at Johnson Avenue
5. Green bike lane markings at intersections and driveway conflict areas
6. Modified northbound striping between Johnson Avenue and the high school
driveway to improve visibility and reduce conflicts where the bike lane shifts
position
If the Council and community members would like to explore more substantive
improvements for San Luis Drive, staff would recommend that this be considered as a
potential funding request at a future financial planning cycle and begin with a more
focused corridor study and safe routes to school plan for San Luis High School .
Page 263 of 412
Item 7b
Pavement Area 2
Figure 5: Pavement Management Area 2 Boundary
Pavement Area 2 includes a series of neighborhood streets near Sinsheimer Elementary
School where staff are proposing targeted traffic calming, pedestrian safety, and striping
improvements to address speeding concerns and enhance multimodal comfort.
Improvements include:
1. Safe routes to school enhancements along Augusta Street, including striped
bulbouts at the Augusta Street and Bishop Street intersection, green-colored
sharrow bike route markings, new/refreshed school zone warning and speed limit
signs, high-visibility crosswalk markings.
2. Install two new speed cushions on Augusta between Sinsheimer Elementary and
Laurel Lane, which implemented a planned Neighborhood Traffic Management
(NTM) request. (As with Mill Street, speed cushions will be installed following
completion of sealing project via separate construction contract).
3. Addition of one new speed cushion on Sydney Street between Johnson and
Augusta, as requested via a current NTM application, which will reduce illegal
speeding on priority walking route to Sinsheimer Elementary.
4. Red curb paint installation for “daylighting” at crosswalks near Sinsheimer
Elementary.
5. Add edge stripes and a centerline stripe on Ella Street to the narrow roadway and
encourage lower speeds, which advances a current NTM request for Ella Street.
The City’s Active Transportation Plan (See Attachment A of ATP for project lists) identifies
several Tier 3 (low priority) bikeway improvements within Pavement Area 2, which are not
recommended for advancement with the 2026 Roadway Sealing Project, for the following
reasons:
1. Flora-Fixilini Neighborhood Greenway – This future neighborhood greenway would
designate a priority walking/bicycle route along Fixilini and Flora Streets, providing
Page 264 of 412
Item 7b
a parallel low-stress pedestrian and bicycle route to Johnson Avenue between
Southwood and SLO High School. There is currently a gap in connectivity between
Fixilini and Flora Streets—to provide a proper connection, a shared-use path is
proposed to be constructed through the County’s property adjacent to the newly
constructed County Probation Building; however, this is not feasible at this time.
The environmental approval for the County’s Campus Redevelopment Phase 1
(the Probation Building) establishes a commitment to construct this path with
Phase 2 of the Campus Redevelopment, which does not yet have a confirmed
schedule. Until then, an informal, partially unpaved pedestrian route will be
retained through the County’s property, but this does not preclude the need for a
proper path in the future.
2. Ella-Ruth-Iris Neighborhood Greenway – Requires construction of shared-use
path along Union Pacific Railroad UPRR property between Jennifer Street bridge
and Iris Street to avoid steep grades.
3. Bishop Street Bike Lanes – Requires removal of on-street parking fronting Terrace
Hill and has limited utility without planned extension of Bishop S treet to
Roundhouse Street over UPRR tracks.
These projects would remain in the ATP for future development.
Pavement Area 3
Figure 6: Pavement Management Area 3 Boundary
Pavement Area 3 includes a mixture of neighborhood streets west of Broad Street and
along Tank Farm Road east of Broad Street. Improvements include:
1. Implement the Meadow Park Neighborhood Greenway east of Broad Street,
following the Mutsuhito Avenue, Victoria Avenue, and Woodbridge Street
alignment (Tier 3 ATP project) with installation of greenway pavement markings
and guide signage. (The remaining portion of the Meadow Park Greenway
extending west of Broad Street is anticipated to be implemented through upcoming
Page 265 of 412
Item 7b
capital projects, including the Higuera Complete Streets Project and the South
Street and King Street Crossing).
2. Installation of red curb paint for “daylighting” at intersections near Meadow Park,
Islay Park and French Park, and at access points to the off -street trail system in
neighborhoods south of Tank Farm Road.
3. Installation of sharrows to delineate the Poinsettia/Fuller bike route per the ATP.
4. High-visibility crosswalk markings at the Poinsettia Drive and Fuller Road
intersection near French Park.
South Broad Street (Tank Farm to Southern City Limit)
South Broad Street between Tank Farm Road and the southern city limit is identified in
the City’s Active Transportation Plan as a Tier 1, or high‑priority, corridor with long‑term
plans to implement protected bike lanes. The corridor is also identified in the City’s Vision
Zero Plan as part of the High‑Injury Network due to its history of severe injury collisions,
with future recommendations to install raised medians, a future signal or roundabout at
Farmhouse Lane, new sidewalks, lighting, and protected bike lanes.
As part of the 2026 Roadway Sealing Project, South Broad Street is identified for roadway
maintenance, with the base bid including crack sealing, and a bid additive alternative
featuring slurry seal and full corridor restriping. Based on current estimates, staff does not
expect existing funding to be sufficient to fund this additive alternative; however, staff is
including this in the bid package to confirm expected costs and with hopes that bids will
come in at a level that allows advancing this work. Staff has incorporated minor
enhancements in the current plans that could be reasonably advanced with the roadway
restriping work if there is sufficient funding to advance the bid additive alternative scope
at this time, including slight reductions in vehicle lane widths to increase existing bike lane
buffer widths where feasible, and installation of green bike lane markings through
intersection conflict areas. It should also be noted that left‑turn access restrictions are
planned at the intersection of Broad Street and Aerovista to eliminate left turns from
Aerovista onto Broad. These turn restrictions are intended to address a history of severe
broadside collisions and while reflected in the current bid additive alternative plans, these
improvements will be advanced this summer as a stand-alone safety project, separate
from the 2026 Roadway Slurry Project. Left-turn access in to Aerovista from Broad Street
will be retained, while drivers turning left out to northbound Broad Street wil l be required
to re-route to the signal at Aero Drive. Potential impacts to the Aero Drive intersection
have been evaluated and additional left -turn demand from these re-routed trips will not
result in degradation to intersection levels of service or queueing.
While implementation of more substantive improvements identified in the ATP and Draft
Vision Zero Action Plan, such as addition of protected bike lanes, raised medians, new
sidewalks, or new signals/roundabouts are no t feasible currently due to funding
constraints, the corridor remains a priority for future improvements. As the Council is likely
aware, the City is initiating planning efforts this spring to advance a corridor study for the
South Broad Street Corridor, covering limits from High Street south to the southern city
limits (near Farmhouse Lane). This separate planning effort, partially funded by a federal
Safe Streets and Roads for All (SS4A) grant, will guide plans for near - and long-term
engineering recommendations for this corridor to improve safety, and will also direct low-
Page 266 of 412
Item 7b
cost, quick-build safety improvements along the segment of Broad between South Street
and Orcutt Road. A separate item will come before the City Council this spring in late May
or early June with more information on this project.
South Street
South Street is identified in the Active Transportation Plan as a Tier 1, or high‑priority,
corridor with plans to pursue protected bike lanes in the future. Although South Street is
not scheduled for pavement maintenance this year and is proposed for striping only as
part of the 2026 Roadway Sealing Project base bid, staff recommends minor refinements
to the eastbound bike lane striping. These include adding striped bike lane buffers where
width allows. The proposed layout shifts the bike lane to the curbside and adds a striped
buffer between vehicle traffic and the bike lane in areas where on‑street parking is
already prohibited.
Previous Council or Advisory Body Action
The City’s Active Transportation Committee (ATC) reviewed draft Project plans on
January 15, 2026. The committee expressed general support for the draft design
measures, and provided the following specific focused recommendations to staff and the
City Council for consideration:
1. Support for adding speed cushions on Mill Street and converting the Mill Street
and Toro intersection to all-way stop control with enhanced crosswalks.
2. Support for the two speed cushions initially proposed for Augusta Street, and
recommendation to add speed cushion(s) on Sydney St reet between Johnson and
Augusta, as requested by neighbors.
3. Recommend that staff investigate a more robust signalization, or possible
roundabout at San Luis Drive and California Boulevard intersection through future
budget recommendations, and Safe Routes to School efforts.
4. The Committee recommends a road-diet down to one lane for room for a buffered
bike lane along Johnson Avenue, between San Luis Drive and Bishop Street.
The current proposed project plans reflect the ATC’s recommendations, except for
Johnson Avenue. As previously described in this report, the plans for Johnson Avenue
do not include a road diet at this time. The ATC staff report and minutes from this meeting
are available in the City’s website.
Staff also presented draft project plans to the City’s Mass Transportation Committee
(MTC) on March 11, 2026. Although there are no improvements within the scope of this
sealing project that are specifically focused on transit access or operations, the committee
expressed support for feasible pedestrian access enhancements near transit stops.
These include the proposed intersection daylighting locations and the pedestrian
crosswalk markings included in the project. The MTC staff report for this item is available
on the City’s website.
Page 267 of 412
Item 7b
Public Engagement
The January 2026 ATC meeting included advanced notification efforts to encourage input
and attendance from the broader community. Prior to the meeting, news releases were
published inviting interested community members to participate. In addition, mailers were
sent to residents on Mill Street and Augusta Street, where proposed street design
changes included new traffic calming measures and intersection control modifications.
The March 2026 MTC meeting was also open to the public.
Following the ATC and MTC meetings, staff sent follow‑up mailers to property owners
and residents on Mill Street to inform stakeholders of the final recommendations for traffic
calming and the Mill Street and Toro Street intersection configuration. Pre‑paid ballots
were also mailed to properties along Augusta and Sydney Streets to gauge support for
the proposed traffic calming measures. Staff has since received a substantial number of
ballots, with strong support for the proposed treatments: 78 percent (94 ballots returned)
in favor on Augusta Street and 84 percent (19 ballots returned) in favor on Sydney Street.
This project is included in the SLO in Motion campaign, which provides updated
information to the community on current and upcoming construction projects in the public
right‑of‑way. Updated project information has been maintained throughout the planning
and design phase at www.slocity.org/sloinmotion. Project information has also been
shared via social media and direct mailers.
CONCURRENCE
This project has been reviewed and has concurrence from the Public Works Department
and Fire Department. Project plans were also reviewed with SLO Transit operators and
design refinements have been incorporated to retain/improve transit vehicle operations ,
where feasible.
ENVIRONMENTAL REVIEW
The Project qualifies for an Exemption to the California Environmental Quality Act
pursuant to State CEQA Guidelines Sections 15301 (Existing Facilities) because the
Project consists of the repair and maintenance of existing roadways, and minimally
disruptive surface improvements within an existing built urban environment (pavement
markings, sign posts, etc.). A Notice of Exemption will be filed through the Community
Development Department upon Council approval of the project.

Item 7b
The 2026 Roadway Sealing Project bid plans and specifications are structured with a
Base Bid and one Additive Alternatives, with Additive Alternative A representing work on
Broad Street south of Tank Farm. The strategy is to award the construction contract with
the Base Bid and Additive Alternative A up to the Publicly Disclosed amount of $3,932,000
in compliance with Public Contract Code Section 20103.8(c).
The total project cost is estimated at $4,851,400, including direct construction costs and
contingencies, as well as related soft costs (construction engineering support, materials
testing, etc.). Excluding the Bid Additive Alternatives, the total Base Bid project cost is
$4,286,394 (construction, contingency and soft costs).
The 2026 Roadway Sealing Project is recommended for award prior to the start of the
new fiscal year, with construction beginning after July 1, 2026, when FY 2026 ‑27 funds
become available. If full funding is not available, only the portion of work that can be
supported within the approved budget will be awarded.
Staff recommends advertising the project now rather than waiting for the start of FY
2026‑27 to enable construction to begin during the late summer to help minimize impacts
on the traveling public. Starting construction earlier than fall will allow school areas to be
prioritized before they’re in session. Any school areas noted in the project specials that
are in session during construction will require work time restriction s.
Construction will not begin until sufficient funding is confirmed to support total project
costs. Actual costs will be known once bids are received.
ALTERNATIVES
1. Deny the approval to advertise the project. City Council could choose to deny
authorization to advertise this project at this time. This action would delay scheduled
road maintenance, which could result in increased future costs due to construction
cost escalation and further deterioration of pavement and road markings.
2. Pursue further analysis, outreach, and design for a potential road concept on
Johnson Avenue. The City Council may choose to direct staff to further evaluate the
potential for a road diet between San Luis Drive and Bishop Street, as recommended
by the Active Transportation Committee (ATC). Should the Council wish to pursue this
alternative, staff would need additional time to conduct expanded public outreach,
coordinate with local emergency services, refine technical analyses (such as a Traffic
Operations Analysis and a Project‑Specific Evacuation Study), prepare more detailed
design concepts for a road diet, and return to both the ATC and the City Council for
final design and policy guidance before moving forward with construction.
Given current limited staffing resources available support new initiatives, these
additional tasks would be expected to require approximately 12-18 months and may
necessitate supplemental funding for consultant support to advance technical studies
and design work.

Item 7b
If the Council selects this alternative, staff recommends authorizing release of the
2026 Roadway Sealing Project for construction advertisement with the Johnson
Avenue plans removed from the scope of work, delegating authority to the City
Engineer to approve amended plans and specifications. Staff would then return to
the Council with updated recommendations and refined design options for a
potential road diet on Johnson Avenue, most likely for inclusion in the 2027 Paving
Project.
Staff also invites any specific policy direction the Council would like prioritized in a road
diet concept, such as dedicating available width to increase on‑street parking, enhancing
bicycle facilities, or other desired design outcomes.

Luke Schwartz, P.E., Transportation Manager
SUBJECT: PRELIMINARY TRAFFIC OPERATIONS ANALYSIS FOR JOHNSON AVENUE
ROAD DIET (SAN LUIS DRIVE TO BISHOP STREET)
INTRODUCTION
The purpose of this memorandum is to document the operational analysis and design
considerations associated with potential traffic lane reductions (“road diet”) on Johnson Avenue
from San Luis Drive to Bishop Street. This analysis was prepared to evaluate the potential impacts
to traffic operations associated with removing one or multiple motor vehicle lanes on Johnson
Avenue to provide width for other features, such as buffered/protected bike lanes, a wider center
turn lane, on-street parking, or simply to encourage slower speeds and fewer conflicts points. This
is a high-level evaluation that includes analysis of operations at the four (4) signalized
intersections on this segment (San Luis Drive, Lizzie Street, Ella Street, and Bishop Street) and
analysis of road segment travel times and speeds. Traffic volumes used in this analysis are based
on counts collected in 2022, which are the most current data available in this corridor.
EXISTING CONDITIONS
Johnson Avenue between Bishop Street and San Luis Drive currently operates as a four-lane
undivided arterial, consisting of two travel lanes in each direction, striped Class II bicycle lanes in
each direction, a continuous two-way left-turn lane between Fixlini and San Luis Drive, and
dedicated left turn lanes at each intersection. The total curb-to-curb width within this segment is
approximately 60 feet. The posted speed limit is 35 mph (prevailing speeds are 38 mph) and
existing weekday traffic volumes range from apx. 15,000 to 16,000 vehicles per day. Peak period
volumes are typically higher in the northbound direction in the AM and higher in the southbound
direction in the PM, with slightly higher total daily volume and highest peak hourly volume in the
southbound direction.
The corridor serves as a key north-south connection within the City network, providing access to
residential neighborhoods, commercial businesses, San Luis Obispo High School, and French
Hospital Medical Center. Over the most recent 5-year period where crash data is available (2020-
2024), there have been 26 total crashes reported on the segment of Johnson Avenue from San
Luis Drive to Bishop Street, including 0 severe injury crashes, 2 crashes involving bicyclists and
Page 275 of 412

0 crashes involving pedestrians. As presented in the Draft Vision Zero Action Plan, this segment
of Johnson Avenue is not designated as part of the City’s High-Injury Network, nor do any
intersections or road segments along this stretch rank among the top “hot spot” locations for
higher-than-average crash rates.
A representative cross section of the existing lane configuration is shown below in Figure 1.
Figure 1: Existing Typical Cross-Section
ROAD DIET ALTERNATIVES CONSIDERED
Three road diet alternatives were evaluated for the purpose of this analysis:
1. Road Diet (Both Directions) – Remove one motor vehicle lane in northbound and
southbound directions
2. Road Diet (Northbound Only) – Remove one motor vehicle lane in the northbound
direction only
3. Road Diet (Southbound Only) – Remove one motor vehicle lane in the southbound
direction only
The roadway width gained from removing one through lane in each direction could allow for
installation of buffered or protected bike lanes and/or potential to add on-street parking—if on-
street parking were to be proposed, buffered bike lanes stripes could be provided, but there would
be insufficient width for vertical bikeway protection.
The northbound-only road diet alternative would remove one of the two northbound through lanes,
while maintaining two through lanes in the southbound direction and a continuous center turn
lane.
The southbound-only road diet alternative would remove one of the two southbound through
lanes, while maintaining two through lanes in the northbound direction and a continuous center
turn lane. With either of these two partial road diet alternatives alternatives, the roadway width
could be repurposed to provide buffered or protected bicycle lanes in each direction. Conceptual
cross sections showing potential configurations for these alternatives are shown Figures 2A-4
below—note that specific design details and cross section widths are shown for reference
purposes only and could be subject to further design refinement.

addition of bikeway vertical elements may not be feasible within current funding limits and would
require further evaluation with City emergency services and maintenance staff.
ANALYSIS METHODOLOGY
Traffic operations were evaluated consistent with City’s Traffic Impact Analysis Guidelines using
the methodologies of the latest edition of the Highway Capacity Manual (HCM). Existing AM and
PM peak hour volumes were analyzed and compared to projected operations under the potential
road diet scenarios using HCM methods using Synchro 11 analysis software. Detailed output
tables are provided as attachments to this report. Intersection vehicle delay and Level of Service
(LOS) were evaluated for each scenario and compared to the adopted performance thresholds
established in the City’s General Plan Circulation Element. In addition, intersection 95th percentile
vehicle queues1 were compared to available storage lengths and roadway link distances, and
roadway segment travel times and speeds were estimated.
Level of Service is a qualitative metric used in transportation engineering to measure and describe
performance of transportation facilities. Level of Service grades range from “A” to “F” and
represent the quality of traffic flow based on congestion when evaluating motor vehicle
performance. LOS “A” reflects free-flow conditions, while LOS “F” represents severe congestion
and excessive delay, with demand exceeding roadway capacity. The Circulation Element of the
City’s General Plan establishes a minimum LOS standard of “D” or better for all routes outside of
the downtown area.
For the purposes of this analysis, delays were evaluated at each signalized intersection along the
Johnson Avenue corridor between San Luis Drive and Bishop for each approach and for the
overall intersection average under existing conditions and under each of the road diet scenarios.
A level of service deficiency would be triggered where intersection delays increase at a location
already operating at LOS E or worse, where design changes cause intersections Levels of Service
1 The 95th percentile queue is the queue length (measured in feet or number of vehicles) that has only a
5% probability of being exceeded during a given analysis period. It is a traffic engineering metric used to
design turn pockets, design traffic signal timing, and evaluate impacts of roadway design changes or land
use projects.

to deteriorate from acceptable (LOS D or better) to unacceptable (LOS E or F), or where
intersection 95th percentile queues would extend beyond available left-turn pocket storage or spill
back into the nearest upstream intersection.
Attachment 1 summarizes intersection delays and level of service, while Attachment 2
summarizes intersection queuing results. Attachment 3 summarizes the arterial road segment
analysis.
OPERATIONS ANALYSIS FINDINGS
Under existing conditions, all intersections operate at with an overall grade of LOS “C” or better
during both peak periods, with the exception of Johnson and Ella during the AM peak, which
currently operates at LOS “E.” It is worth noting that at both the Lizzie Street and Ella Street
intersections, some individual side street approaches currently operate below LOS “D” during
existing peak hour conditions. The deficient movement varies by peak period and does not
necessarily occur in the same direction during both the AM and PM peaks.
Under all road diet scenarios evaluated, study intersections experience increased delay during
both the AM and PM peak hours. Based on the analysis results, one or more intersections would
operate below the City’s minimum LOS “D” standard on an overall basis, and several individual
approaches would decrease operations significantly, with the worst operating at LOS “F” and
experiencing substantial delay. In practical terms, this would result in some side-street
movements experiencing delays approaching or exceeding five minutes to clear the intersection.
Queue lengths during the AM and PM peak hours were also evaluated. Under existing conditions,
queues are generally contained within available turn lane storage, and through movements do
not spill back into upstream intersections. Under the road diet configurations, 95th percentile
queues increase significantly due to reduced directional capacity. As a result, queues would
exceed available turn bay storage and would spill back into upstream intersections. At some
locations, actual queues could be longer than predicted using this software analysis model. For
example, in certain scenarios, queues on Johnson Avenue would spill back into multiple upstream
signalized intersections—the this queue spillback would increase delays and queues at the
adjacent upstream intersection further, but would not be fully captured in this software modeling.
in these instances, actual queue lengths may extend further than predicted by the software
modeling. In addition, during AM and PM bell times at SLO High School, queues from the school
often spill back to Johnson Avenue, which could further increase queues and delays upstream.
A few specific examples of what drivers may experience during peak commute periods with
implementation of a road diet:
Johnson & Lizzie Intersection – During AM peak, increase in overall intersection delay of
45 seconds/vehicle and eastbound approach delay exceeding 200 seconds/vehicle. Peak
northbound queues increase by 400 feet, nearly spilling back to the upstream Ella Street
intersection.
Johnson & Ella Intersection – During AM peak, increase in overall intersection delay of
over 2 minutes (125 seconds) per vehicle and the northbound approach delay exceeds
300 seconds/vehicle (5+ minute delay). During AM peak, northbound approach peak
Page 279 of 412

queues increase to >1,000 feet, nearly spilling back to the upstream Bishop Street
intersection. During the PM peak, southbound approach peak queues increase to >1,000
feet, through the upstream Lizzie Street intersection.
In addition to individual intersection analysis for delay and queueing, an arterial segment analysis
was conducted to evaluate potential changes to segment travel times and speeds along Johnson
Avenue between Bishop Street and San Luis Drive with a potential road diet. Results indicate that
under a full road diet scenario, northbound travel times in the AM peak increase by over 60%,
while southbound travel times in the PM peak increase by over 100%. Average speeds in both
directions are reduced to under 10 mph during peak periods. Similar trends are observed under
the directional road diet scenarios. Under the northbound-only configuration, northbound AM peak
travel times increase by over 40%, while under the southbound-only configuration, southbound
PM peak travel times increase by over 100%.
While no traffic operations models can perfectly predict traffic operations changes from street
redesign projects, staff has observed real-word instances of significant traffic congestion, delays,
and queuing on this portion of Johnson Avenue during peak commute periods when construction
work has required temporarily closing traffic lanes. These observations would support the general
results from the modeling analysis predicting significant traffic congestion with a road diet.
EMERGENCY RESPONSE CONSIDERATIONS
In addition to the above operational analysis, City Transportation Engineering staff discussed the
potential for a road diet on Johnson Avenue with the San Luis Obispo Fire Department (SLO Fire).
SLO Fire expressed concerns that the added congestion resulting from a road die could impact
emergency response along this segment of Johnson Avenue, which is identified as a primary
cross-town emergency response route, with particular sensitivity to increasing delays accessing
the French Hospital Medical Center. Increased congestion and queue spillback under the road
diet configurations could increase emergency response times, especially during peak travel
periods. While emergency vehicle preemption (EVP) equipment could help minimize some
disruption to emergency vehicle response (all intersections within this study area have existing
EVP equipment, except Johnson/Bishop), this remains a concern for City emergency response
representatives.
Furthermore, the neighborhoods surrounding the Johnson Avenue corridor, including the
neighborhoods to the north near SLO High School, are designated by Cal Fire as “high” and “very
high” fire hazard severity zones, which highlights the importance of Johnson Avenue to serve as
a likely emergency evacuation route in the case of a large wildfire. Significant reductions in vehicle
throughput capacity may affect the corridor’s ability to accommodate peak demand during a
potential evacuation. Further evaluation would be necessary to fully assess potential impacts to
emergency response operations and evacuation performance prior to implementation of any
roadway reconfiguration.
CONCLUSIONS
Based on the operational analysis conducted for Johnson Avenue between Bishop Street and
San Luis Drive, none of the road diet alternatives evaluated are recommended at this time. While
the proposed configurations could allow for enhanced bicycle facilities, addition of on-street
Page 280 of 412

parking, or potential for reduced speeds and intersection conflicts, or other multimodal
improvements, all scenarios result in increased delays, degraded Level of Service, and extended
queue lengths during peak hour conditions that would exceed the City’s adopted policy
thresholds. Under the road diet alternatives, one or more intersections would operate below the
City’s adopted LOS “D” standard on an overall basis, and multiple individual approaches would
experience extensive delay, including LOS “F” conditions in certain cases. In addition, 95th
percentile queues would exceed available storage lengths and spill back into upstream
intersections, disrupting corridor progression and reducing operational reliability.
This evaluation was conducted at a preliminary level of detail using traffic counts collected in
2022, which represent the most recent data available for this corridor. The analysis reflects current
traffic volumes only and does not incorporate projected future growth. Given the operational
deficiencies identified under current conditions, it is reasonable to expect that future increases in
traffic volumes would further exacerbate delay and queue impacts under any of the road diet
configurations. Emergency access and evacuation considerations further reinforce these findings.
Increased congestion and queue spillback may impede emergency vehicle response to French
Hospital Medical Center and could affect the corridor’s function as an evacuation route serving
adjacent high fire risk areas. For these reasons, implementation of a full road diet, northbound-
only road diet, or southbound-only road diet on this segment of Johnson Avenue is not
recommended by staff at this time without further study. If further consideration for a road diet
configuration is desired, it is recommended that additional traffic operations analysis be conducted
using new traffic count data and including future year scenarios and an early afternoon peak hour
during the SLO High School afternoon bell time. Future analysis should also consider multimodal
level of service, preparation of a detailed emergency evacuation study to evaluate potential
impacts on evacuation clearance times.

NOTES:
1) All road diet scenarios assume signal timings have been optimized with a maximum of 120 second cycle length.
2) Queuing results reflect 95th percentile queues. The 95th percentile queue is a standard metric used in traffic engineering for street design and traffic impact analyses. This
represents the estimated peak queue length (measured in feet) that has a 5% probability of being exceeded during a peak hour analysis period. In the results above, traffic
volumes exceed capacity at several locations and traffic analysis models may not accurately estimate peak queue lenghts -- actual queue lengths may exceed these values at
times during peak periods.
3) Locations highlighed red where 95th percentile queues exceed existing turn lane storage or where through lane queues would spill back and block the nearest upstream
intersection.
4) 25' was used as the minimum queue length due to engineering best practice considering 25 feet the equivalent of one car length.
5) The letter "m" is used to denote intersection movements that are metered by the upstream signal.
Results are based on high-level modeling approach, actual results are likely to be worse.

Add green bike lane markings through intersection conflict areas
Left turn restrictions on Aerovista: High crash rate (2 fatal broadside crashes in
last 5 years) -- planned summer 2026 with/without sealing project)
Johnson Avenue (Bishop to Buchon)
Planning Context:
ATP Tier 2 Project – calls for protected bike lanes, may require lane reductions or road widening
Safety History
26 crashes in 5 years, 0 severe/fatal, 2 bicycle crash, 0 ped crashes
Not part of VZ High-Injury Network, crash concentrations at Johnson/San Luis Drive and Johnson/Lizzie
Speeds
Posted = 35 mph
Prevailing Speed = 38 mph
Johnson Avenue
(Bishop to Buchon)
Key commute corridor, route to SLO High,
many driveways, varying topography
Existing: 5 traffic lanes, paint-only bike
lanes, all min widths per City Stds
Too narrow to add buffered/protected bike
lanes without removing traffic lanes
Pavement in poor quality beyond slurry
seal – 2026 Project includes striping only
Staff evaluated feasibility of potential road
diet – has been successful elsewhere on

Existing
Full Road Diet
NB or SB Only Road Diet
Traffic Operations Analysis
General Plan Threshold = Auto LOS D or better. LOS E or F shown in red
Traffic Operations Study Results
What do these results mean?
All road diet scenarios result in deficient LOS, queues – significant congestion
during peak commute periods
Delays of 5 minutes or more at some intersection approaches during peak
periods
Queues spill back to upstream intersections during peak periods
Travel Times double for some scenarios/directions
Results may be optimistic –more robust analysis needed for more confidence
Real world observations during construction supports congestion levels
forecasted in model.
Emergency Response & Evacuation Considerations
Concerns with added congestion & delays along
primary response route, particularly to French Hospital
Johnson Ave key evacuation route, particularly SB
away from San Luis Drive neighborhood and hillside to
east (limited alternate routes, flood risk)
Egress to SB Johnson challenging during recent fire
above SLO High
What is proposed in 2026 Sealing Project?
Bike lane buffer stripe where width allows
Under rail bridge (Buchon to SLD)
SB uphill between Fixilini and Bishop
Green bike lane markings in conflict zones
2 Radar Speed Feedback Signs & more speed
limit signs
“35 MPH” speed limit markings
Johnson Avenue Questions:
What would the Johnson/San Luis Dr intersection look like with a road
diet?
Do the current plans advance recommendations for Johnson per the
Draft Vision Zero Action Plan?
Can you provide more details on recent crash history, and what is the
confidence level on the data used?
What is the cost savings if the Council decides not to move forward with
work on Johnson with 2026 Roadway Sealing Project?
How does the publicly disclosed funding amount of $3,932,000 relate to
the construction cost figures shown in the Fiscal Impact section of staff
report?
Johnson Avenue Questions:
What would the Johnson/San
Luis Dr intersection look like
with a road diet?
Johnson Avenue Questions:
Do the current plans advance recommendations for Johnson per the Draft
Vision Zero Action Plan?
Johnson (SLD to Bishop) not on High-Injury Network or “Hot Spot” location
Increase awareness of speed limits with more signs, markings, radar signs
Green bike lane markings at conflict points
Bike box and sign/striping refinements at Johnson/San Luis Drive intersection
Can you provide more details on recent crash history, and what is the
confidence level on the data used?
Variety of crash types, concentrations at SLD, Lizzie, many speed related
2 bike crashes at Johnson/Lizzie
1 NB right hook vs. NB thru cyclist (bike brake malfunction a factor)
1 NB scooter traving wrong way in SB bike lane vs. EB right vehicle
Johnson Avenue Questions:
What is the cost savings if the Council decides not to move forward with
work on Johnson with 2026 Roadway Sealing Project?
Apx. $300,000 in cost reduction if Johnson pulled from project scope
Pavement on Johnson in bad shape, beyond slurry seal
Striping condition ok, could last 1-2 more years before full refresh
Public Engagement
Project website, news release, coordination with SLO Fire
and SLO Transit, SLO High School, SLCUSD
Direct mailers to Mill Street and neighborhoods where traffic
calming is proposed
Neighborhood ballots to Augusta and Sydney show 78%-84%
support for speed cushions
Mill Street neighborhood majority support removal of pilot
traffic circle, replace with all-way stop at Mill/Toro
Sydney Street traffic calming added at request of community
to advance NTM project already in queue
Advisory Body Input
ATC
Generally supportive of design proposals, including traffic calming
and all-way stop at Mill/Toro
Recommended pursuing road diet on Johnson Avenue to reduce
speeds and prioritize comfort and safety for ped/bike users
Supportive of more robust safe routes to school planning and
improvements on San Luis Drive for SLO High School access
MTC
Supportive of plans, requests continued focus on pedestrian
access and crossing safety improvements near transit stops
Fiscal Impact
Costs:
Total Funding = $4.85 million
*Total Cost = $4.85 million
o Base Bid Cost = $4.29 million
o Bid Add Alt Cost (including contingency, etc.) = $565k
*Includes direct costs, construction management and contingencies
Publicly Disclosed Funding ($3,932,000) – most we can award to
construction contract, while retaining sufficient funds for contingency,
construction management, materials testing, etc.
Next Steps
1.Spring 2026 – Advertise for construction
2.Early Fall 2026 – Start construction
3.Early 2027 – Construction Complete
Questions?
Recommendations:
1.Approve the project plans and special provisions for the 2026 Roadway
Sealing Project, Specification Number 2000617; and
2.Authorize staff to advertise for bids for the 2026 Roadway Sealing Project;
and
3.Authorize the City Manager to award the construction contract for the
2026 Roadway Sealing Project pursuant to Section 3.24.190 of the
Municipal Code for the bid total, if the lowest responsible bid is within the
publicly disclosed funding amount of $3,932,000; and
3.Appropriate $236,542 from the unreserved SB1 Fund balance to the
project; and,
Recommendations (cont.):
5.Adopt a Resolution (Attachment C) entitled, “A Resolution of the City
Council of the City of San Luis Obispo, California, Authorizing
Appropriation of $236,542 from unreserved SB1 Fund Balance to support
the 2026 Roadway Sealing Project, Specification Number 2000617; and,
6.Authorize the Finance Director to make the following transfers to the 2026
Roadway Sealing Project Account (2000617):
a)Transfer $62,000 of Capital Outlay LRM from Bridge Maintenance
(2000029); and,
b)Transfer $100,000 of Capital Outlay LRM from the Traffic Maintenance
and Replacement Project Account (No. 2001003); and,
c)Transfer $150,000 from Completed Projects; and,
7.Authorize the City Engineer to approve Contract Change Orders up to the
available project budget, including any amendments authorized by the City
Manager.
Alternatives
1.Deny the approval to advertise the project. City Council could choose to deny authorization to
advertise this project at this time. This action would delay scheduled road maintenance, which could
result in increased future costs due to construction cost escalation and further deterioration of
pavement and road markings.
2.Pursue further analysis, outreach, and design for a potential road concept on Johnson
Avenue. The City Council may choose to direct staff to further evaluate the potential for a road diet
between San Luis Drive and Bishop Street, as recommended by the Active Transportation
Committee (ATC). Should the Council wish to pursue this alternative, staff would need additional
time to conduct expanded public outreach, coordinate with local emergency services, refine
technical analyses (such as a Traffic Operations Analysis and a Project-Specific Evacuation Study),
prepare more detailed design concepts for a road diet, and return to both the ATC and the City
Council for final design and policy guidance before moving forward with construction.
Given current limited staffing resources available support new initiatives, these additional tasks
would be expected to require approximately 12-18 months and may necessitate supplemental
funding for consultant support to advance technical studies and design work.
