Prepared by: Pam Kobylarz, Assistant to the Town Manager Recommended Motion: Approve proclamation declaring May 3-9, 2026 as Public Service Recognition Week

PUBLIC SERVICE RECOGNITION WEEK
In honor of the millions of public employees at the federal, state, county, and town levels:

Whereas, Americans are served every single day by public servants at the federal, state, county, and town levels. These unsung heroes do the work that keeps our nation working; and Whereas, public employees take not only jobs, but oaths; and Whereas, many public servants, including military personnel, police officers, firefighters, border patrol officers, embassy employees, health care professionals and others, risk their lives each day in service to the people of the United States and around the world; and
Whereas, public servants include teachers, doctors, scientists, astronauts, nurses, safety inspectors, laborers, computer technicians, social workers, and countless other occupations. Day in and day out they provide the diverse services demanded by the American people of their government with efficiency and integrity; and
Whereas, without these public servants at every level, continuity would be impossible in a democracy that regularly changes its leaders and elected officials; and Whereas, talent is a key differentiator in organizations in today’s world. At the Town of Mammoth Lakes, our talent creates our solutions, our products, and our services. Our talent serves our customers and manages the important work of the organization every day; and Whereas, locally Town staff provides services to this community, including parks and road maintenance, public safety, planning and permitting, community recreation programs, and many other services that contribute to our vibrant community; and
Whereas, the Town has many elected and appointed officials and volunteers, including the Town Council, Planning and Economic Development Commissioners, Recreation Commissioners, and other volunteers, whose service to the Town is invaluable.

Therefore, the Town Council of the Town of Mammoth Lakes does hereby proclaim to all citizens, that May 3-9, 2026, is Public Service Recognition Week. All citizens are encouraged to recognize the accomplishments and contributions of government employees and volunteers at all levels – federal, state, county, and town.

Proclaimed this 6
th day of May, 2026.

1 TOWN COUNCIL STAFF REPORT
Title: Receive a presentation on Defining Middle-Income Housing Meeting Date: May 6, 2026
Prepared by: Marcus Sproll, Housing Manager
RECOMMENDATION:

This is an informational only item. Town Council can discuss and ask questions of staff.

BACKGROUND:

The Town of Mammoth Lakes adopted the Housing Now! initiative in 2019 to provide a range of community housing that is available and affordable to those working in the community. To date, most of the housing created under this initiative has been in the lowincome category due to the requirements of state and federal funding sources. The March 2026 Regional Housing Needs Study (“2026 Housing Study”) identified that the current highest housing need for the Town is in the middle-income category, with a high demand for smaller rental units (1-bedroom units) that are attainable for local middle-income workers. Input from community members, employers, and the Town Council support this conclusion.

Over the next two months, staff will provide several presentations to inform Town Council and the public about middle-income rental housing and a project proposal. This series will culminate with a request for the Town Council to decide whether to proceed with a project of this type and if so, a request to commit existing and future Measure L revenue and other Housing-committed funds to the future project. The schedule of these presentations is below:

2 ANALYSIS:

The following data points are from the 2026 Housing Study and highlight the need for additional housing stock that is targeted to middle-income households.

Population growth in the Town has been negative over the last fifteen years and households are getting smaller. The Town lost approximately 1,200 residents, or 14.5 percent of its total population, from 2010 to 2025; the largest loss of any jurisdiction in the region. This population decline is expected to continue, driven in part by an acute shortage of available long-term housing for the resident workforce. During the same period, the average household size declined by 25 percent, from 2.8 persons in 2010 to 2.1 persons in 2024, with approximately 35 percent of households in the Town being single-person households.

This reduction in household size has resulted in a need for more rental units since multigenerational households are less common and living with roommates is less desirable.

Nearly two-thirds of employers surveyed for this research reported that housing availability hampers recruitment and retention, with businesses estimating they could grow 23 percent more over the next five years on average, if adequate workforce housing options were available. Employers cited a need for all types of housing, with a particular need for rental housing units.

Due to the recent delivery of a significant number of low-income housing units, the largest need cohort in the Town now falls into the middle-income category. The study finds the greatest unmet need to be smaller middle-income households earning up to 120 percent of AMI that are best served by studio and one-bedroom rental units.

The current housing inventory in the Town is approximately 9,650 residential units. Two thirds (6,331 units) of this inventory is comprised of vacant second homes, meaning they are not primary residences. The remaining third (3,318 units) of the inventory is occupied by local residents as their primary dwelling. Approximately 18 percent (624) of the occupied units are deed-restricted as affordable housing by various state, federal, and local programs, with almost all being restricted to low-income households.

Of the 3,318 occupied housing units, 1,845 are owner-occupied, and 1,473 are rentals. The rental housing inventory of 1,473 units can be divided into three segments: 1) 46 percent are market-rate multifamily apartment housing with 2 or more units; 2) 17 precent are market-rate single-unit rentals – condominium units or single-family homes; and 3) 37 percent are deed-restricted affordable units. The single-unit rentals in particular are the most unstable, as they are primarily second homes that are subject to frequent entry and exit from the rental market and volatile rental pricing.

The ideal rental housing landscape in Mammoth Lakes would be comprised of Market-rate Housing, Employee Housing, Low-Income Affordable Housing, and Middle-Income Workforce Housing.
 Market-rate housing has the benefit of being unrestricted and most flexible, but rents are highest and there is a significant lack of inventory. Market rents in the

3 Town are generally about 15 percent higher than major California cities, and 10 percent higher than peer resort towns in Colorado and Utah. Mammoth rents are most similar to rents in Vail and Breckenridge, both in Colorado.  Employee housing has the benefit of directly meeting an employer’s housing needs, but design and rules may not support long-term tenancy.  Low-income housing serves an important segment of the community, and the Town has made significant progress in providing these types of units.  Middle-income workforce rental housing represents the current highest need but is the most challenging to finance since most State and Federal programs don’t support units at these incomes and is instead dependent on local funding sources.

The benefit to this funding source is that the local entity can decide what the requirements (AMI, rents, etc.) for the units are. Middle-income rents are tailored to those earning between 81 percent and 120 percent of AMI. Workers in this income category include small business owners, nurses, teachers, retail managers, firefighters, and town or county administrative staff. Hourly wages in this category are about $26 - $40 with individual annual salaries between $62k and $83k.

Affordable rents for a one-bedroom unit in this category are between $2,000 to $2,800 per month, compared to average market rent of approximately $2,700.

In summary, the current Mammoth Lakes housing inventory has a majority of vacant second homes, with approximately 3,318 units occupied by local resident households. Of these occupied units, 1,473 are rentals, with 37 percent of these being deed-restricted rentals; mostly low-income units. The unrestricted market rentals cannot meet the housing demand from the middle-income workers, and there is a need for large-scale development of new middle-income rental housing inventory, with a focus on one-bedroom units in the 90 percent to 110 percent of AMI range. This type of new housing would add stability to the rental market, provide a modern high quality living environment, and reduce utility bills with energy-efficient design and building systems.

NEXT STEPS
Staff will be coming to Town Council over the next two months with a series of informational presentations on middle-income rental housing. The next presentation will be on the challenges of financing middle-income housing.

Facility Update

What is the Dave and Roma
McCoy Arts & Cultural
Center?
• The Dave and Roma McCoy Arts and Cultural Center is a performing arts venue developed through a partnership between the Town of Mammoth Lakes and the Mammoth Lakes Foundation.
• Honoring the legacy of Dave and Roma McCoy, the facility reflects their enduring vision for a culturally rich and connected community. • This venue will serve as a regional hub for arts, culture, and education with supporting performances, films, lectures, and community programming that advance artistic excellence and civic engagement. • The project consists of a single-story theater addition of approximately 7,482 sq. ft. built as an expansion of the existing Edison Hall. • Funding for the project was provided by various partners including the Kern Community College District (Measure C), Mammoth Lakes Foundation, Tambour Foundation, and the Town's General Fund & Measure U. • The Town's Parks and Recreation Department will manage the facility and coordinate programming with the Chamber Music Unbound, Sierra Classic Theatre, Mammoth Lakes Repertory Theatre, Mammoth Lakes Film Festival, and the Eastern Sierra Community Chorus to name a few.

Construction Update
• Construction began in August 2025 – slight delay due to SCE power-off work • Underground utilities, foundations, concrete slab, and partial-height concrete columns were completed prior to the winter season
• During winter, progress was made towards completing interior renovations of the Edison Theater
• We are investigating other potential improvements to both interior and exterior – entrance columns, exterior rock, siding, and windows for WUI compliance, existing lobby enhancements, air conditioning
• Current work – exterior CMU block walls, full-height concrete columns, steel roof structure, and site work later this summer.
• Expected completion spring/summer 2027 (many variables in play)

The Vision

Focusing the Vision
In service of the original MLF vision, AMS has kept these key questions in mind to guide our work:
• What are the current needs of the community and collective goals and vision for a new performing arts venue? How have they changed over time? What remains the same? • How does the project need to be positioned to achieve success and long-term sustainability?
• With the facility now under construction, how can it be best optimized for highest/best use for the benefit of the community?
• What is the most efficient way for the Town to operate the building? • What resources are required to achieve success?

relationship between a performing arts center
and its content providers
Landlords Rent to providers that come to them
• Booking is not proactive, typically no at-risk performances Hosts Provide a home to resident companies
• Residents/regular renters provide the majority of programming, other dates are proactively booked, risk is shared
Presenters Take responsibility for procuring content
• Proactive booking of the calendar, majority at-risk activity Operators

1 TOWN COUNCIL STAFF REPORT
Title: Resolution to approve the FY2026-27 project list to be submitted to the California Transportation Commission (CTC) for funding from the Road Maintenance and Rehabilitation Account (RMRA) funds under Streets and Highways Code Section 2034.

Meeting Date: May 6, 2026
Prepared by: Haislip Hayes, PE Public Works Director
RECOMMENDATION:

Adopt a resolution approving the 2026-27 project list to be submitted to the California Transportation Commission (CTC) for funding from the Road Maintenance and Rehabilitation Account (RMRA) funds under Streets and Highways Code Section 2034.

BACKGROUND:

On April 28, 2017 the Governor signed into law SB1. SB1 invests $5.4 billion annually over a decade to fix California’s transportation system. In November of 2017 the State Controller began depositing funding into the newly created Road Maintenance and Rehabilitation Account (RMRA). A percentage of this new RMRA funding will be apportioned by formula to eligible cities and counties. The funding provides a balance of new revenues and reasonable reforms to ensure efficiency, accountability, and performance from each dollar invested in the transportation system.

In order to be eligible for funding the Town is required to sustain a Maintenance of Effort (MOE) and may not supplant current efforts. Annually, prior to receiving funds, a proposed project list which contains the description and location, schedule for completion, and estimated useful life of the improvement must be adopted by resolution. Upon completion of the FY, a project expenditure report must be submitted to the State. RMRA funding may be used for road maintenance and rehabilitation, safety projects, traffic control devices, complete streets components, and to match State and Federal grants.

In September of 2026, Staff provided an update on CIP projects to Council. Staff recommendations for SB1 funding support and complement these projects. Previous SB1 resolutions have resulted in the completion of two curb and gutter rehabilitation projects along Meridian Blvd. In 2020 Staff utilized SB1 funding to support the construction of the Lake Mary Sidewalk project located adjacent to the brewery. In 2022 Staff recommended using Town and County SB1 funds to support road and sidewalk projects. Recently, SB1 funds were used to complete the Chaparral Road extension in the Parcel.

2 ANALYSIS:

The Town’s projected RMRA revenue for FY 26-27 is approximately $195,542. In 2026 Staff identified priority projects that address many of the Town’s current needs. These projects are ongoing, and it is recommended that 26-27 SB1 funds be used to supplement construction of these existing projects:

1. 2026 Slurry and Fog Seal Project
a. Location: The “Slopes” Neighborhood in Mammoth Lakes, CA. b. Scope: slurry seal, fog seal, painted traffic striping and pavement marking at a variety of roads throughout the Town of Mammoth Lakes. c. Useful life: This project is expected to have a useful life of 20 years d. Schedule: The project would be awarded in May or June, and construction will commence in summer 2026.

FINANCIAL CONSIDERATIONS:

Approval of the project list above permits the State Controller’s Office to disperse funding to the Town monthly. Staff will use these funds to fully fund SB1 approved projects. Staff will return to Council with any scope changes that would require additional resources or funding.

ENVIRONMENTAL CONSIDERATIONS:

Generally, road and sidewalk maintenance projects are categorically exempt from CEQA.

Each project will be evaluated independently to determine if there is an impact to the environment. This analysis will be provided to Council as required and as appropriate.

RESOLUTION NO. 26-

RESOLUTION OF THE TOWN COUNCIL OF THE TOWN OF MAMMOTH LAKES, STATE OF CALIFORNIA, TO INCORPORATE INTO THE FISCAL YEAR 2026-27 BUDGET A LIST OF PROJECTS FUNDED BY SB 1: THE ROAD REPAIR AND ACCOUNTABILITY ACT WHEREAS, Senate Bill 1 (SB 1), the Road Repair and Accountability Act of 2017 (Chapter 5, Statutes of 2017) was passed by the Legislature and Signed into law by the Governor in April 2017 in order to address the significant multi-modal transportation funding shortfalls statewide; and WHEREAS, SB 1 includes accountability and transparency provisions that will ensure the residents of the Town of Mammoth Lakes are aware of the projects proposed for funding in our community and which projects have been completed each fiscal year; and WHEREAS, the Town of Mammoth Lakes must include a list of all projects proposed to receive funding from the Road Maintenance and Rehabilitation Account (RMRA), created by SB 1, in the Town of Mammoth Lakes budget, which must include a description and the location of each proposed project, a proposed schedule for the project’s completion, and the estimated useful life of the improvement; and WHEREAS, the Town of Mammoth Lakes, will receive an estimated $195,542 in RMRA funding in Fiscal Year 2026-27 from SB 1; and
WHEREAS, the Town of Mammoth Lakes has undergone a public process to ensure public input into our community’s transportation priorities/the project list; and WHEREAS, the Town of Mammoth Lakes used a Pavement Management System to prioritize asphalt projects on the SB 1 project list to ensure revenues are being used on the most high-priority and cost-effective projects that also meet the community’s priorities for transportation investment; and WHEREAS, the funding from SB 1 will help the Town of Mammoth Lakes maintain and rehabilitate streets and add active transportation infrastructure throughout the Town of Mammoth Lakes this year and similar projects into the future; and
WHEREAS, the 2018 California Statewide Local Streets and Roads Needs Assessment found that the Town of Mammoth Lakes’ streets and roads are in “at-risk” condition, and this revenue will help us increase the overall quality of our road system and over the next decade will bring our streets and roads into a “good” condition; and
WHEREAS, without revenue from SB 1, the Town of Mammoth Lakes, would not have had the funding to complete the proposed maintenance projects throughout the community; and WHEREAS, if the Legislature and Governor failed to act, city streets and county roads would have continued to deteriorate, having many and varied negative impacts on our community; and WHEREAS, maintaining and preserving the local street and road system in good condition will reduce drive times and traffic congestion, improve bicycle safety, and make the pedestrian experience safer and more appealing, which leads to reduced vehicle emissions helping the State achieve its air quality and greenhouse gas emissions reductions goals; and
WHEREAS, restoring roads before they fail also reduces construction time which results in less air pollution from heavy equipment and less water pollution from site run-off; and

Resolution No. 26-

WHEREAS, the SB 1 project list and overall investment in our local streets and roads infrastructure with a focus on basic maintenance and safety, investing in complete streets infrastructure, and using cutting-edge technology, materials and practices, will have significant positive co-benefits statewide.

NOW, THEREFORE IT IS HEREBY RESOLVED, ORDERED AND FOUND by the Town Council of the Town of Mammoth Lakes, State of California, as follows:

1. The foregoing recitals are true and correct.

2. A $195,542 budget for fiscal year 2026-27 will incorporate the following projects described in the planned to be supported with RMRA revenues:

1. 2026 Slurry and Fog Seal Project
a. Location: The “Slopes” Neighborhood in Mammoth Lakes, CA. b. Scope: slurry seal, fog seal, painted traffic striping and pavement marking at a variety of roads throughout the Town of Mammoth Lakes.
c. Useful life: This project is expected to have a useful life of 20 years d. Schedule: The project would be awarded in May or June, and construction will commence in summer 2026.

3. The Public Works road rehabilitation maintenance budget for fiscal year 2026-27 will include an additional $195,542 earmarked to be used only for the projects listed above.

PASSED AND ADOPTED by the Town Council of the Town of Mammoth Lakes, State of California, this 6th day of May, 2026.

APPROVED AND ADOPTED THIS 6th DAY OF MAY 2026

In order to be eligible for implementation grant funds a comprehensive safety action plan is required. The Town was successful in its application and was awarded $80,000 in grant funds to be matched with Local Transportation Commission (LTC) planning funds. In May of 2025 the Town Council authorized the Town Manager to contract with Kimley-Horn and Associates to complete the Safety Action Plan.

ANALYSIS:

The goal of the SAP is to develop a holistic, well-defined strategy to prevent roadway fatalities and serious injuries. A successful SAP includes the following seven key components:

1. Leadership commitment and goal setting

2. Planning structure

3. Safety analysis

4. Engagement and collaboration

5. Policy and process changes

6. Strategy and project selections

7. Progress and transparency
The Town of Mammoth Lakes SAP evaluates the transportation network as well as noninfrastructure programs and policies within the Town. Mitigation measures are evaluated using criteria to analyze the safety of road users (drivers and passengers, bicyclists, and pedestrians), the interaction of modes, influences on the roadway network from adjacent municipalities, and the potential benefits of safety countermeasures. The Federal Highway Administration (FHWA) maintains a list of proven safety countermeasures. The list

2 currently has 20 Proven Safety Countermeasures, and SAPs are included on the list. The SAP documents the results of data and information obtained, including the vision, goals, and objectives for the SAP; existing safety efforts; crash analyses; emphasis areas; the Town’s existing countermeasure toolbox; and potential countermeasures for select case study locations.

Public outreach efforts included developing a stakeholder group and in person and online surveys. Project stakeholders were identified and included in the development of the SAP to maintain a local perspective. The project stakeholder group was comprised of staff from various Town departments as well as key community members. The stakeholder group met in-person on October 27th, 2025, to review the results of the network screening analysis, in-person community event, and provide comments about case study locations. The Stakeholder Group identified several safety topics that are outlined in the plan. KimleyHorn’s Public Engagement Plan for the Town of Mammoth Lakes SAP included strategies and activities to reach a broad cross-section of the community throughout the Town. The plan included one in-person community engagement event, focused on identifying intersection/corridor needs and opportunities which is further detailed in this report. The outreach occurred between August and December 2025 and consisted of three main components: an in-person pop-up event (Winter Expo), online survey for public input in multiple languages and finally, an online Interactive Map hosted on PublicCoordinate which the public identified areas of concern throughout the Town. The results of these efforts are included in detail in the plan.

Online surveys (Figure 1) collected from various efforts revealed that eighty-six percent of the respondents live within the Town of Mammoth Lakes. The largest proportion of respondents noted that they mainly depend on vehicles as their primary mode of travel, Figure 1- Public Outreach Flyer

3 though a large proportion also walk. When asked to identify their top three areas of traffic safety challenges when it came to traveling throughout the Town, most individuals noted concerns with aggressive driving, pedestrian crossings, and electric mobility (E-bikes).

Other key themes from the 162 surveys completed are as follows:

1. Street Lighting/Nighttime Visibility – pedestrian and vehicle safety along roadways at night was a concern

2. Unsafe Vehicle Speeds - Concerns about speeding drivers, especially on Main Street and by the Village.

3. Snow Removal/Icy Roads - snow banks can obstruct sight distance and pavement markings. Walking around the Town is difficult in winter conditions.

4. Parking Enforcement – vehicles illegally parking by Davison Rd/Rainbow Ln or unsafely parked on Forest Trail.

5. Pedestrian Crossings – pedestrians have witnessed vehicles not yielding to pedestrians in the crosswalk, despite the flashing beacons along Main St or the pedestrian signal by the village being activated.

6. School Safety – respondents note that the intersection of Meridian Road and Sierra Park Rd can get congested during school drop-off and pickup times. A crossing guard could help

7. Safely facilitate students through the area and potentially ensure more efficient vehicle operations.

8. Road Maintenance and Infrastructure - A need for better road quality and safe infrastructure for all road users, especially at high-traffic points.

The online public engagement website (Figure 2) contained a community map where respondents selected locations within the Town where they experienced traffic safety issues and identified the specific issue(s) from a list of pre-populated challenges. The community map received 111 posts, and 132 instances of engagement. Approximately 49% of comments were regarding pedestrian safety and 29% were focused on vehicle safety.

Bicycle safety concerns accounted for 12% of comments and included comments about Ebikes.

Figure 2 - Snapshot of the engagement website
The systemic improvements identified as most likely to be effective for the Town of Mammoth Lakes are listed in the SAP and include a wide range of countermeasures

4 (Figure 3) that can be implemented in phases where appropriate. Many of these proposed countermeasures have already been or are planned to be implemented in the Town, including but not limited to pedestrian countdown signal heads, conversion of stopcontrolled intersections to roundabouts, and installation of retro-reflective backplates on traffic signal heads.

Figure 3 - Table 6 of the SAP counter measures
The Town identified case study locations from the network screening analysis. Figure 4 presents the case study locations and in the SAP contains notes for why these locations were prioritized. During coordination with the stakeholder group and public engagement additional locations and safety improvements were identified, beyond those included in the case study locations. While not all of these locations were highlighted in the data analysis section of the report, this SAP recognizes the significance of these locations and has incorporated recommended actions into this document. The locations generally included signalized and unsignalized intersections. A variety of treatments are recommended to make these areas safer.

5 Figure 4- Case Study Locations
Implementation of the SAP can be accomplished through development and implementation of safety improvement projects and strategies, the establishment of new/updated policies and programs, and development/strengthening of relationships with stakeholders. Staff intend to incorporate SAP projects into the CIP and apply for grants to fund implementation. Grant opportunities are available now and staff are working with its grant writing consultant to complete a competitive application. The approval of the SAP by resolution is required to access these funding opportunities.

FINANCIAL CONSIDERATIONS:

The plan was funded entirely with grants. $80,000 in US DOT SS4A grant funds and Local Transportation Commission appropriated Regional Planning Assistance funds. The Town will need to identify funding to implement the proposed projects and countermeasures identified in the plan.

ENVIRONMENTAL CONSIDERATIONS:

None at this time.

Town of Mammoth Lakes SS4A Safety Action Plan 1 March 2026

1. INTRODUCTION
The Town of Mammoth Lakes is an established mountain community located in eastern California, approximately 35 miles southeast of Yosemite National Park. The Town has a population of approximately 7,600 residents, encompassing roughly 25 square miles. Mammoth Lakes welcomes up to 1.3 million and 1.5 million tourists in the respective winter and summer seasons1, with as many as 40,000 people visiting the Town on peak days2. Mammoth Lakes’ transportation network includes an extensive system of Town-maintained roadways that serve both residents and a substantial seasonal visitor population, with traffic control devices concentrated along key arterial and collector corridors.

The Town does not have a previous Safety Action Plan (SAP) developed. As such, this SAP identifies priority emphasis areas and systemic strategies that can be implemented to further improve safety for all roadway users. This SAP analyzes the most recent five years of available crash data spanning from January 1, 2020 through December 31, 2024, evaluating crash trends observed during the COVID-19 pandemic and in the years following as travel patterns and roadway conditions stabilized.

1.1. Safe Streets and Roads for All (SS4A) Program
This SAP was prepared with funding from the Safe Street and Roads for All (SS4A) discretionary program. The Town of Mammoth Lakes received an SS4A planning grant to develop a new SAP. The Bipartisan Infrastructure Law (BIL) established the SS4A discretionary program to fund improvements and strategies to prevent roadway fatalities and serious injuries of all users of highways, streets, and roadways: pedestrians, bicyclists, public transportation users, motorists, personal conveyance and micro-mobility users, and commercial vehicle operators. The SS4A program supports the U.S. Department of Transportation’s (USDOT’s) National Roadway Safety Strategy (NRSS) and a goal of zero roadway deaths using a Safe System Approach. The program includes $5 billion in appropriated funds over five years: 2022-2026. This SAP meets eligibility requirements that allow local jurisdictions to apply for implementation grants and additional funding through the USDOT SS4A discretionary program.

Town of Mammoth Lakes SS4A Safety Action Plan 2 March 2026

1.2. Safe System Approach
The USDOT has adopted a Safe System Approach as the
guiding paradigm to address roadway safety. The Safe System Approach has been embraced as an effective way to address and mitigate the risks inherent in our complex transportation system. It works by building and reinforcing multiple layers of protection to both prevent crashes from happening in the first place and minimize the harm caused to those involved when crashes do occur. The Safe System Approach is founded on the principles that humans make mistakes and that human bodies have limited ability to tolerate crashes. It provides a holistic and comprehensive approach to roadway safety and is governed by the framework shown in Figure 1. The Safe System Approach is a shift from the conventional approach to roadway safety because it focuses on both human mistakes and human
vulnerability, and designs for a system with many redundancies in place to protect everyone.

1.3. National Roadway Safety Strategy (NRSS)
USDOT’s NRSS is a comprehensive approach to reduce fatal and serious injuries on highways, roads, and streets. This strategy outlines the USDOT’s long-term goal of reaching zero roadway fatalities, the adoption of the Safe System Approach, and actions the department will take to target urgent problems. The NRSS states that across the nation, rural roads face safety impacts that largely outnumber their relative population and number of miles traveled. This leads to a fatality rate that is approximately two times higher on rural roads than on urban roads.

1.4. What is a SAP?
A SAP is intended to result in holistic, well-defined strategies intended to reduce roadway fatalities and serious injuries within a specific locality, tribal area, or region. SAPs can take many forms; however, to be eligible for Implementation and/or Planning and Demonstration funding through the USDOT SS4A discretionary grant program, the SAP is required to be completed within the time period specified for the Notice of Funding Opportunity (NOFO) period (generally within the last five years) and must include the following two components: (1) Safety Analysis and (2) Strategy and Project Selections, as well as at least three of the following elements:
• Leadership commitment and goal setting
• Planning structure
• Engagement and collaboration
• Policy and process changes
• Progress and transparency
More information about SAPs is available on the USDOT SS4A website.

This SAP uses a risk factor analysis to identify and prioritize locations for proactive safety improvements that can be implemented by the Town of Mammoth Lakes, allowing practitioners to make informed, prioritized safety decisions. The recommendations focus on systemic Figure 1 — USDOT Safe System Approach

Town of Mammoth Lakes SS4A Safety Action Plan 3 March 2026 transportation improvements with high crash reduction benefits and include proven safety countermeasures.

The planning process takes constraints within the local roadway network into consideration and incorporates feedback from the Town of Mammoth Lakes Public Works team and local stakeholders including partners within the Five Es of traffic safety defined by the California Strategic Highway Safety Plan (SHSP): Engineering, Enforcement, Education, Emergency Response, and Emerging Technologies. While engineering improvements can make the roadways safer, engineering improvements alone cannot prevent all motor vehicle crashes. According to the National Highway Traffic Safety Administration (NHTSA), over 90 percent of all crashes are the result of driver-related factors. Because such a high percentage of crashes are a result of driver-related factors, making roadways safer requires input from all five Es.

2. VISION, GOAL, AND OBJECTIVES
The Town of Mammoth Lakes SAP evaluates the transportation network as well as non-infrastructure programs and policies within the Town. Mitigation measures are evaluated using criteria to analyze the safety of road users (drivers and passengers, bicyclists, and pedestrians), the interaction of modes, influences on the roadway network from adjacent municipalities, and the potential benefits of safety countermeasures. This effort is intended to use historical data to identify trends and develop a toolbox of countermeasures applicable to conditions in the Town that can be used for proactive identification and implementation of opportunities, without relying solely on a reaction and response to crashes as they occur.

The Federal Highway Administration (FHWA) maintains a list of Proven Safety Countermeasures. The list currently has 20 Proven Safety Countermeasures, and SAPs are included on the list of 20 Proven Safety Countermeasures. Implementation of SAPs has improved safety in local jurisdictions across the country by providing a guide for local jurisdictions to systemically address the conditions that lead to fatal and severe injury crashes. They provide a locally developed and customized roadmap to directly address the most common safety challenges in the given jurisdiction. Following discussions with the Town’s staff and a review of existing plans and policies for the area, the following Vision, Goal, and Objectives have been established for this project.

Vision: Support the California vision of eliminating traffic-related fatalities and severe injuries by creating a proactive, community-driven, and implementable safety program for all road users in the Town of Mammoth Lakes.

Goal: Identify and prioritize actionable transportation safety projects and policy initiatives— based on crash data, known safety concerns, and community input—that can be immediately advanced, incorporated into the Town’s Capital Improvement Program (CIP), and positioned for grant funding.

Objectives: ▪ Identify and prioritize high-risk locations and systemic safety issues using crash data analysis and known concerns, including speeding, e-bike safety, snow removal operations, parking management in the Lakes Basin, and pedestrian safety.
▪ Explore how safety challenges can be addressed through new policies and programs, including school crossing guards and E-bike safety. ▪ Develop a short list of implementable safety projects suitable for near-term CIP inclusion and competitive state and federal safety grants, ensuring the plan directly informs funding and implementation decisions.
▪ Identify cost-effective and scalable systemic countermeasures that can be applied systemwide (e.g., speed management treatments, high-visibility pedestrian improvements, flashing yellow arrows, retroreflective backplates, leading pedestrian intervals, and e-bike-specific safety treatments). ▪ Promote safe, equitable, and multimodal mobility for residents, visitors, and employees, with particular focus on pedestrians, bicyclists, and e-bike users. ▪ Encourage participation from local businesses, community members, and partner agencies to support education, outreach, coordination with agencies such as the United States Forest Service (USFS), and shared responsibility for roadway safety.
▪ Document procedures for ongoing crash data monitoring and performance tracking to support continuous improvement and future updates.

3. STAKEHOLDER ENGAGEMENT
Project stakeholders were identified and included in the development of the SAP to maintain a local perspective. The project stakeholder group was comprised of staff from various Town departments as well as key community members. A complete list is available in the acknowledgements on Page iii. The stakeholder group provided input on safety challenges in the Town and reviewed the draft SAP. Numerous strategic safety projects in this SAP were identified through discussions and collaboration with the stakeholder group. The stakeholder group will continue to be engaged as Town staff move forward with these projects in coordination with the school district, fire district, and police department. It is anticipated that Town staff will also coordinate with the stakeholder group to monitor the Town’s safety performance moving forward.

These stakeholders were called together to offer insight on the safety challenges present in the Town’s transportation network. The stakeholder group first met virtually on August 5 th, 2025 for an
overview of the project and to provide initial comments on road safety in Mammoth Lakes (Figure 2).

The stakeholder group met in-person on October 27th, 2025 to review the results of the network screening analysis, in-person community event, and provide comments about case study locations.

Figure 2 — Town of Mammoth Lakes Stakeholder Meeting
The stakeholder group identified the following safety topics:
• The crash data collected by the Mammoth Lakes Police Department (PD) is understood to be incomplete. Most crashes which result in property damage only are not reported to Mammoth PD. The stakeholder group understands that more crashes occur on Town roads than are represented in the SAP.

Town of Mammoth Lakes SS4A Safety Action Plan 7 March 2026 • E-bike safety along Lake Mary Road and elsewhere across the Town continues to be a challenge area for the Town. This includes both tourists and community members. • Meridian Boulevard has observed speed exceeding the posted speed by over 20 mph. • The intersection of Meridian Boulevard and Sierra Park Road is a priority for the Town and the schools in the area. The Town is considering establishing a crossing guard program to ensure student safety during school peak hours.
• Some drivers mistake the transverse striped crosswalks on Old Mammoth Road and other areas in the Town as stop bars and stop at an uncontrolled intersection resulting in rear-end crashes.
• On the one-way section of Lakeview Boulevard and Rainbow Avenue, vehicles are parked on both sides of the road despite signage and ticketing near the Canyon ski lift during the ski season. These parked cars block the road, restricting access for emergency response vehicles. In emergencies, these vehicles must be towed, which is cumbersome as the Town has one tow company who tows to a small impound lot.
• The Mammoth Middle School driveway (near College Parkway on Meridian Boulevard) has large embankments on both sides limiting sight distance to trail users. • The Town does not currently use thermoplastic striping but is researching the best practices for recessed thermoplastic striping from other jurisdictions in California that have snow conditions.

4. PUBLIC OUTREACH

4.1. Introduction
Kimley-Horn’s Public Engagement Plan for the Town of Mammoth Lakes SAP included strategies and activities to reach a broad cross-section of the community throughout the Town. The plan included one in-person community engagement event, focused on identifying intersection/corridor needs and opportunities which is further detailed in this report.

Prior to launching the public-facing effort, the Town of Mammoth Lakes and Kimley-Horn teams met to discuss and plan out key project deliverables and how public engagement would inform and support these efforts.

The outreach occurred between August and December 2025 and consisted of three main components:

1. In-person pop-up event (Winter Expo)

2. Online survey for public input in multiple languages

3. Online Interactive Map hosted on PublicCoordinate which the public identified areas of concern throughout the Town.

Public engagement officially launched on August 1, 2025, when the online material became available.

On October 2, 2025, the team attended the pop-up event held at the Town of Mammoth Lakes’ second annual Winter Expo held at the Community Recreation Center. The event has open ice skating as well as over ten booths comprised of various topics such as parks and recreation and youth hockey sign-up. Kimley-Horn staff engaged with attendees of the Winter Expo to gather feedback and capture community concerns on comment cards and encouraged feedback through the online survey.

The online survey was also promoted
through the Town’s various
communication channels, including a
webpage, e-newsletters, and the palm
cards/poster boards created for the
pop-up event. A record of public
comments is included in Appendix A.

4.2.1. Winter Expo – October 2, 2025
5:00 pm – 7:30 pm
Kimley-Horn kicked off the engagement pop-ups for the Town of Mammoth Lakes at the second annual Winter Expo held at the Community Recreation Center, with a large proportion of attendees at this event being local residents. Interactive map poster boards were stationed at the in-person event, allowing participants to visualize the study area and place numbered dots where they experienced traffic related challenges or would benefit from safety improvements in those areas throughout the Town. There were also palm cards available with project information and a link to the online materials (survey and PublicCoordinate site).

Three map poster boards were up on display and had moderate engagement. Engagement yielded:
• Approximately 30 total people surveyed
• 24 poster board map interactions
• A handful of very passionate residents, verbally shared concerns and suggestions • Distributed over 40 postcards with a QR code to the online survey Public comments received at the Winter Expo are included in Appendix A.

Town of Mammoth Lakes SS4A Safety Action Plan 10 March 2026

4.3. Online Community Survey Responses
The in-person and online engagement resulted in a total of 162 survey respondents. Outreach efforts at the Winter Expo yielded in-person responses, while the online survey received the most input after the email to town residents was sent out with links to the website and survey. The website received 111 site-specific comments.

4.3.1. Online Map & Survey Engagement
The online survey collected from various efforts revealed that most respondents (86%) indicated that they reside in the Town of Mammoth Lakes. Approximately 4% of survey respondents live in unincorporated Mono County and 3% live in Bishop. A large proportion of respondents engage in recreation in Mammoth Lakes, work or own a business in the Town.

Survey respondents were asked to choose the top three challenges they face while travelling through Mammoth Lakes. The top three challenges experienced by survey respondents were: 1) aggressive driving (speeding), 2) pedestrian crossing concerns, and 3) electric mobility (unsafe and unlawful use of e-bikes). Many of the other challenges listed on the online survey received large numbers of votes.

The following charts show the responses to the nine survey questions. It should be noted several questions allowed respondents to select multiple responses but did not ask respondents to rank them. Therefore, the total number of responses shown can be more than the total number of completed surveys for the aforementioned reason.

4.3.1.1. Key Themes from the Survey Results
Online surveys collected from various efforts revealed that eighty-six percent of the respondents live within the Town of Mammoth Lakes. The largest proportion of respondents noted that they mainly depend on vehicles as their primary mode of travel, though a large proportion also walk. When asked to identify their top three areas of traffic safety challenges when it came to traveling throughout the Town, most individuals noted concerns with aggressive driving, pedestrian crossings, and electric mobility (E-bikes). Other key themes from the 162 surveys completed are as follows:

1. Street Lighting/Nighttime Visibility – pedestrian and vehicle safety along roadways at night was a concern

2. Unsafe Vehicle Speeds - Concerns about speeding drivers, especially on Main Street and by the Village.

3. Snow Removal/Icy Roads - snow banks can obstruct sight distance and pavement markings. Walking around the Town is difficult in winter conditions.

4. Parking Enforcement – vehicles illegally parking by Davison Rd/Rainbow Ln or unsafely parked on Forest Trail.

5. Pedestrian Crossings – pedestrians have witnessed vehicles not yielding to pedestrians in the crosswalk, despite the flashing beacons along Main St or the pedestrian signal by the village being activated.

6. School Safety – respondents note that the intersection of Meridian Road and Sierra Park Rd can get congested during school drop-off and pickup times. A crossing guard could help safely facilitate students through the area and potentially ensure more efficient vehicle operations.

7. Road Maintenance and Infrastructure - A need for better road quality and safe infrastructure for all road users, especially at high-traffic points.

4.3.1.2. Community Map
The online public engagement website also contained a community map where respondents selected locations within the Town where they experienced traffic safety issues and identified the specific issue(s) from a list of pre-populated challenges (Figure 3). The community map received 111 posts, and 132 instances of engagement. Approximately 49% of comments were regarding pedestrian safety and 29% were focused on vehicle safety. Bicycle safety concerns accounted for 12% of comments and included comments about E-bikes.

5. REVIEW OF TOWN PLANNING DOCUMENTS
Existing plans, policies, and projects that were recently completed, planned, or are on-going within the Town were compiled at the start of the SAP process in order to gain perspective on the existing efforts for transportation safety-related improvements within the Town. High-level key points regarding transportation improvements and safety-related topics were identified to inform decision making in this SAP.

▪ Town of Mammoth Lakes Inn at the Village Report
▪ Town of Mammoth Lakes Trail System Master Plan, 2011
▪ Town of Mammoth Lakes Parks and Recreation Master Plan, 2012 The Town of Mammoth Lakes seeks to improve roadway safety by implementing the Safe System Approach. The Safe System Approach, as defined in the California Department of Transportation (Caltrans) SHSP, is built upon the following principles3:
• Death and serious injuries are unacceptable
• Humans make mistakes
• Humans are vulnerable
• Responsibility is shared
• Safety is proactive
• Redundancy is crucial
While engineering countermeasures are a critical part of preventing fatal and severe injury crashes, the Town also recognizes that policy plays a key role in safety as well.

The Town performed a literature review of relevant
policies and programs to identify other means by which
the Safe System Approach and road safety could be
further established. Appendix B presents a summary of
local programs, policies, and practices as well as
considerations of how they can be improved or
enhanced to further support and prioritize road safety. 3 2020-2024 SHSP – Jan 2023 (PDF), Caltrans. January 2023. dot.ca.gov/-/media/dot-media/programs/safetyprograms/documents/shsp/2023-shsp-full-report-2020-2024-a11y.pdf Source: What Is a Safe System

6. PROCESS
Providing safe, sustainable, and efficient mobility choices for their residents and visitors is a primary goal for the Town and their safety partners. The Town collaborated and discussed with safety partners to develop the SAP and will continue to do so in its implementation.

Guidance on the SAP process is provided at both the national and state levels through the FHWA and Caltrans, respectively. Both agencies have created a basic framework of data and recommendations for inclusion in a SAP.

The FHWA encourages:
• Leadership Commitment & Goal Setting: A jurisdiction formally commits to a zero-fatality goal with a clear target date or reduction timeline.
• Planning Structure: A designated committee or team oversees development, implementation, and monitoring of the Action Plan.
• Safety Analysis: Existing crash data and conditions are analyzed to identify trends, contributing factors, and high-injury network locations. • Engagement & Collaboration: The Plan incorporates robust public and stakeholder input and aligns with other jurisdictions’ plans where applicable. • Policy & Process Changes: Existing policies and standards are reviewed and revised to better prioritize transportation safety.
• Strategy & Project Selections: Data-driven strategies and prioritized projects are identified to address key safety issues using a Safe System Approach. • Progress & Transparency: The jurisdiction reports progress annually and publicly posts updates and the Action Plan to ensure accountability.

Caltrans guidance follows a similar outline with the following steps:

1. Establish leadership

2. Analyze the safety data

3. Determine emphasis areas

4. Identify strategies

5. Prioritize and incorporate strategies

6. Evaluate and update the SAP
This SAP documents the results of data and information obtained, including the vision, goals, and objectives for the SAP; existing safety efforts; crash analyses; emphasis areas; the Town’s existing countermeasure toolbox; and potential countermeasures for select case study locations. The development of the SAP recommendations considers the Five Es of traffic safety defined by the California SHSP: Engineering, Enforcement, Education, Emergency Response, and Emerging Technologies throughout its process.

6.1. Guiding Manuals
The following section describes the analysis process undertaken to evaluate safety within the Town at a systemic level. Using a network screening process, locations within the Town that will most likely benefit from safety enhancements were identified. Using historic crash data, crash risk factors for

Town of Mammoth Lakes SS4A Safety Action Plan 20 March 2026 the entire network are derived. The outcomes will inform the identification and prioritization of engineering and non-infrastructure safety countermeasures that address certain roadway characteristics and related behaviors that contribute to motor vehicle crashes as well as active transportation users.

This process uses the latest national and state best practices for statistical roadway analysis described in the following sections.

6.1.1. Local Roadway Safety: A Manual for California’s Local Road Owners The purpose of the Local Roadway Safety: A Manual for California’s Local Road Owners (Version 1.7, April 2024) (LRSM) is to encourage local agencies to pursue a proactive approach to identifying and analyzing safety issues, while positioning themselves to be eligible for competitive federal, state, and local grant programs for project implementation funding opportunities. A proactive approach is defined as analyzing the safety of the entire roadway network through either a one-time, network wide analysis, or by routine analyses of the roadway network.

According to the LRSM, “Caltrans – Division of Local Assistance is responsible for administering California’s federal safety funding intended for local safety improvements.” To provide the most benefit and to be competitive for grant funding, the analysis leading to countermeasure selection should focus on both intersections and roadway segments and be considerate of roadway characteristics and traffic volumes. The result should be a list of locations that are most likely to benefit from implementation of cost-effective countermeasures, preferably prioritized by benefit/cost ratio. The LRSM suggests using a mixture of quantitative and qualitative measures to identify and rank locations that considers both crash frequency and crash rates. These findings should then be screened for patterns such as crash types and severity to aid in the determination of issues causing higher numbers of crashes and the potential countermeasures that could be most effective. Qualitative analysis should include field visits and a review of existing roadway characteristics and devices. The specific roadway context can then be used to assess what conditions may increase safety risk at the site and systematic level.

Countermeasure selection should be supported using Crash Modification Factors (CMFs). These factors are the peer reviewed product of before and after research that quantifies the expected rate of crash reduction that can be expected from a given countermeasure. If more than one countermeasure is under consideration, the LRSM provides guidance on how to apply CMFs appropriately.

6.1.2. Highway Safety Manual
The American Association of State Highway and Transportation Officials (AASHTO) Highway Safety Manual (HSM), published in 2010, presents a variety of methods for quantitatively estimating crash frequency or severity at a variety of locations. This four-part manual is divided into Parts: A) Introduction, Human Factors, and Fundamentals, B) Roadway Safety Management Process, C) Predictive Method, and D) Crash Modification Factors.

Chapter 4 of Part B of the HSM discusses the network screening process. The network screening process is a tool for an agency to analyze their entire network as well as identify and rank locations that (based on the implementation of a countermeasure) are most to realize a reduction in the frequency of crashes.

Town of Mammoth Lakes SS4A Safety Action Plan 21 March 2026 The HSM identifies five steps in this process:

1. Establish Focus: Identify the purpose or intended outcome of the network screening process. This decision will influence data needs, the selection of performance measures and the screening method that can be applied.

2. Identify Network and Establish Reference Populations: Specify the types of sites or facilities being screened (i.e. segments, intersections, or geometrics) and identify groupings of similar sites or facilities.

3. Select Performance Measures: There are a variety of performance measures available to evaluate the potential to reduce crash frequency at a site. In this step, the performance measure is selected as a function of the screening focus and the data and analytical tools available.

4. Select Screening Method: There are three screening methods described in this chapter:
ranking, sliding window, and peak searching. Each method has advantages and disadvantages; the most appropriate method for a given situation should be selected.

5. Screen and Evaluate Results: The final step in the process is to conduct the screening and analysis and evaluate the results.

The HSM provides several statistical methods for screening roadway networks to identify high risk locations based on overall crash histories. In addition to identifying the total number of crashes, this SAP uses a method referred to as Critical Crash Rate (CCR) to analyze the data.

6.2. Analysis Techniques

6.2.1. Crash and Network Screening Analysis
Intersections and roadways were analyzed using four crash metrics:
▪ Number of Crashes
▪ CCR (HSM Ch. 4)
▪ Probability of Specific Crash Types Exceeding Threshold Proportion (HSM Ch. 4) ▪ Equivalent Property Damage Only (EPDO) (HSM Ch. 4)
The initial steps of the crash analysis established sub-populations of roadway segments and intersections that have similar characteristics. For this SAP, intersections were grouped by their control type (signalized and unsignalized) and segments by their roadway category (arterial, collector, minor collector, and local). Individual crash rates were calculated for each subpopulation. The sub-population level crash rates were then used to assess whether a specific location has more or fewer crashes than expected. These sub-populations were also used to determine typical crash patterns to help identify locations where unusual numbers of specific crash types are occurring.

The network screening process ranks intersections and roadway segments by the number of crashes that occurred at each one over the analysis period, and then identifies areas that had more of a given type of crash than would be expected for that type of location. The crash type factors were:
▪ Crash severity – fatal, severe injury, other visible injury, complaint of pain, and property damage only (PDO)
▪ Crash type – broadside, rear-end, sideswipe, head-on, hit object, overturned, bicycle, pedestrian, and other

Town of Mammoth Lakes SS4A Safety Action Plan 22 March 2026 ▪ Environmental factors – lighting and wet roads
▪ Driver behavior – impaired, aggressive, and distracted driving From the results of the network screening analyses, locations were chosen based on crash activity, crash severity, crash patterns, location type, and area within the Town to provide the greatest variety of locations covering the widest range of safety opportunities for countermeasure toolbox development. The intent is to populate the safety countermeasure toolbox with mitigation measures that will be applicable to most of the crash activity in the Town.

6.2.2. Critical Crash Rate (CCR) Analysis
Reviewing the number of crashes at a location is a good way to understand the cost to society incurred at the local level but does not give a complete indication of the level of risk for those who use that intersection or roadway segment on a daily basis. The HSM describes the critical crash rate (CCR) method, which provides a statistical review of locations to determine where risk is higher than that experienced by other similar locations. It is also the first step in analyzing for patterns that may suggest systemic issues that can be addressed at that location and proactively at others to prevent new safety challenges from emerging.

The CCR compares the observed crash rate to the expected crash rate at a particular location based on facility type and volume using a locally calculated average crash rate for the specific type of intersection or roadway segment being analyzed. Based on traffic volumes and a weighted Townwide crash rate for each facility type, a critical crash rate threshold is established at the 95% confidence level to determine locations with higher crash rates that are unlikely to be random. The threshold is calculated for each location individually based on its traffic volume and the crash profile of similar facilities. A roadway segment with a higher local CCR differential indicates that the segment’s crash rate is higher than expected for its functional classification.

Local CCR Differential Formula:

𝑀𝐸𝑉𝑖 = [

Data Needs
CCR is calculated using:
▪ Daily Total Entering Volume (TEV) for intersections, or Vehicle Miles Traveled (VMT) for roadway segments
▪ Intersection control types to separate them into like populations ▪ Roadway functional classification to separate them into like populations ▪ Crash records in Geographic Information System (GIS) or tabular form including coordinates or linear measures
Strengths Weaknesses
▪ Reduces low volume exaggeration
▪ Considers variance
▪ Establishes comparison threshold
▪ Does not account for regression to the
mean bias
To give an example, the intersection of Old Mammoth Road and Meridian Boulevard experienced 13 crashes during the five-year study period and had a LCCR of negative 0.11 (-0.11). This negative local critical crash rate differential indicates that fewer crashes occurred at the intersection of Old Mammoth Road and Meridian boulevard than would have statistically been expected for this facility type. This may be because property damage only crashes often go unreported within the Town.

6.2.3. Equivalent Property Damage Only (EPDO) Method
The Equivalent Property Damage Only (EPDO) method is described in Chapter 4 of the Highway Safety Manual. This method assigns weighting factors to crashes based on injury level to develop a “property damage only” score. In this analysis, the injury crash costs were calculated for each location based on the latest Caltrans injury costs. This value is then divided by the injury cost for a property damage only crash ($18,000). The resulting number is the equivalent number of property damage only crashes at each site. This value allows all locations to be compared based on injury crash costs. (HSM, Chapter 4).

EPDO Formula (for signalized intersections):

𝐸𝑃𝐷𝑂 =
(𝑁𝐹 + 𝑁𝑆) ∗ $2,162,000 + (𝑁𝑂 ∗ $193,000) + (𝑁𝐶 ∗ $110,000) + (𝑁𝑃𝐷𝑂 ∗ $18,000) $18,000
Where:

EPDO = Equivalent Property Damage Only (in units of crashes)

Town of Mammoth Lakes SS4A Safety Action Plan 24 March 2026 NF = Number of fatal crashes
NS = Number of severe injury crashes
NO = Number of other visible injury crashes
NC = Number of complaint of pain crashes
NPDO = Number of PDO crashes
Source: Highway Safety Manual, 1
st Edition, Pg 4-30
The costs to society for each crash type are as follows:
• Fatal and Severe (Major) Injury: $2,162,000 (signalized intersections), $3,440,000 (unsignalized intersections), $2,978,000 (Roadway Segments) • Other Visible (Minor) Injury: $193,000
• Complaint of Pain: $110,000
• PDO (no injury): $18,000
Source: Caltrans LRSM V1.6 Pg 106
The crash dataset from Mammoth Lakes PD contained crashes resulting in Major Injuries, Minor Injuries, and No Injuries. A secondary crash dataset focused on bicycle incidents was obtained from emergency response services. The bicycle crashes in this secondary dataset were logged as traumatic injuries, and for the sake of the EPDO calculation, are evaluated as Minor Injuries.

To give an example from Appendix C, the unsignalized intersection of Old Mammoth Road and Tavern Road had eight crashes from 2020-2024. The crashes by severity are follows: two crashes resulting in other visible injuries, and six PDO crashes.

The eight crashes of ranging severity that took place at the intersection of Old Mammoth Road and Tavern Road have the equivalent cost to society of approximately 27 PDO crashes. This intersection has a CCR Differential value of 0.13. Together the EPDO and CCR Differential values show that the intersection has historically had a relative crash rate that is higher than expected for similar facilities, and that that the eight crashes that have occurred there have had the equivalent cost to society of 27 property damage only crashes.

A map of intersection and segment EPDO is presented in Figure 5. Locations with fatal and severe injury crashes will have a higher EPDO value compared to locations with less severe injury crashes.

A number of locations with high EPDO values were identified for further study and are discussed in Section 7. Listed below are the roadway segment and intersection with the highest EPDO values:
• The roadway segment with the highest EPDO value was Minaret Road from Main Street/Lake Mary Road to Forest Trail, with an EPDO value of 143 (1 Major Injury crash, 2 Minor Injury crashes, and 1 PDO crash)
• The intersection with the highest EPDO value was Lake Mary Road and Lee Road (unsignalized), with an EPDO value of approximately 206 (1 Major Injury crash, 8 Traumatic (Minor) Injury crashes)
The results of the network screening analysis for both intersections and roadway segments are presented in Appendix C and Appendix D, respectively.

7. DATA SOURCES
The following data was obtained from the Town for use in crash data analysis.

7.1. Roadway Network
The crash analysis, which is described in detail in Section 6, requires each corridor within the Town to be classified. The Town’s roadway network obtained directly from the Town was categorized using Caltrans’ Roadway Functional Classification System provided in the existing roadway network database. The roadway network classification was assigned to each corridor roadway segment as either a major arterial, minor arterial, collector, or local road in order to compare the functional design and capacity to better stratify analysis results, only comparing roadway segment safety performance with similar class roadways (i.e., only arterials are compared to arterials, etc.) within the Town.

7.2. Intersections
The crash analysis also requires each intersection within the Town to be classified by control type.

Intersections throughout the Town were classified by control type as either signalized or unsignalized (including roundabouts). The safety analysis also only compares intersection safety performance with similar control types (i.e., signalized intersections are only compared to signalized intersections, etc.) within the Town.

7.3. Crashes
Collision data for the most recent five-year period (January 1, 2020 through December 31, 2024) was used for the collision analysis. Using data from the past five-year period is sufficient to identify potential trends in crashes by location and types, while not being so long as to have data that would include long-term technology and cultural changes. The collision data was obtained from the Town’s crash database which is maintained by the Town of Mammoth Lakes PD. A secondary dataset containing EMS responses to bicycle-only incidents was also included for analysis. Collision records were allocated to intersection if they were within 250-feet of the intersection, and to a roadway segment if beyond 250-feet.

Knowing the impacts of the crash (the injuries or type of damage which occurred) is a key part of assessing the environment and safety factors around the site of the crash. The National Safety Council developed the “KABCO” injury scale, which is frequently used by law enforcement for classifying injuries. The crash data obtained from Mammoth PD and EMS response are understood to have a injury classification which is comparable to the California KABCO scale used, as follows:

Table 1 — Crash Severity Classification

Severe/Incapacitating
Injury Major Injury
B Other Visible Injury Minor Injury
C Complaint of Pain -

7.4. Roadway Volumes
Roadway volumes were collected to support the development of crash rates at intersections and roadway segments across the Town. Roadway volumes were collected in both August 2025 and January 2026 to approximate average annual daily traffic along key corridors. The data collection sites are presented in Figure 6 and the volumes are included in Appendix E. These volumes were used to calculate relative crash rates at local intersections and roadway segments as presented in Appendix C and Appendix D, respectively. Traffic counts from other projects in the Town were used to supplement these volumes. Vehicle volumes were collected over a twenty-four hour period at the following intersections:
• Main St/Minaret Rd
• Lake Mary Rd/Canyon Blvd
• Minaret Rd/Meridian Blvd
• Minaret Rd/Forest Trail
• Old Mammoth Road/Meridian Road
• Old Mammoth Road/Ski Trails Road and Club Drive
Pedestrian volumes were collected over a twenty-four-hour period at the following locations:
• HAWK signal on CA-203
• Canyon Blvd in the Village
• Meridian Blvd/College Pkwy – eastern approach
• Minaret Rd/Forest Trail

8.3. Severity Level
Over the observed five-year time period, there were a total of 229 crashes, none of which were fatal and 12 of which resulted in majorinjuries (7%), as shown in Figure 7. Just over one-third of all crashes resulted in a minor injury (37%) or no injury (38%). Unsignalized intersections experienced the highest number of injury crashes. A crash is attributed to an intersection if it occurred within 250- feet of an intersection, and to a roadway segment if the crash occurred beyond 250-feet.

Table 4 presents the distribution of all crashes, and especially KA crashes across the Town’s various facility types (signalized intersections, unsignalized intersections, and roadway segments).

Unsignalized intersections experienced the highest proportion of all crashes and major injury crashes. Nearly sixty percent of all crashes occurred at unsignalized intersections, while over 60% of major injury crashes occurred at unsignalized intersections. Signalized intersections experienced approximately twelve percent of crashes and no fatal or major injury crashes. Roadway segments experienced nearly thirty percent of all crashes and thirty-eight percent of major injury crashes.

8.4. Annual Crashes
Figure 10 presents the number of annual crashes on roads in the Town of Mammoth Lakes beginning from 2020 The year with the most crashes was 2023, with a total of 54 crashes. Annual crashes have generally trended upward since 2020, though there were fewer crashes recorded in 2024 than in 2023.

It is likely that the COVID-19 pandemic influenced crash trends in 2020 and 2021. In 2020, the daily household trips were lower due to widespread shelter-in-place orders; fewer vehicles on the road could be connected to fewer vehicle conflicts and thus fewer crashes. However, reduced roadway volumes and congestion could also be connected to increased vehicle speeds, a phenomenon that numerous law enforcement agencies have reported. As traffic volumes rose in 2021 with the return of tourism and outdoor recreation demand, law enforcement agencies in California anecdotally noted that vehicle speeds remained high; it is theorized that this pandemic-era aggressive driving behavior has persisted and is partially contributing to the increase in annual crashes than can be seen since 2020 (Figure 10).

8.7. Lane Departure Crashes
Caltrans defines crashes involving lane departure as those with crash types listed as ‘Head-On’, ‘HitObject’, or ‘Overturned’. This also includes instances where a vehicle runs off the road or crosses into the opposing lane prior to the crash. There were 55 lane departure crashes over the study period in the Town, with an average of 11 lane departure crashes per year. Of the 55 lane departure crashes, zero were fatal, 6 were reported with major injuries, 21 were reported with minor injuries and 28 with no reports of injuries.

8.8.1. Aggressive Driving Crashes
Aggressive driving includes primary collision factors such as unsafe speed, following too closely and violations related to traffic signals and signs. There were 64 aggressive driving crashes between 2020-2024. Two of the crashes resulted in major injuries and 37 resulted in minor injuries. Figure 16 illustrates the aggressive driving crashes within the Town.

8.8.2. Impaired Driving Crashes
Impaired driving crashes include all crashes where there was evidence of drug or alcohol use by the driver. Drivers do not need to exceed the legally defined threshold of intoxication to be counted, as Caltrans considers any level of alcohol consumption to have the potential to impact driver responsiveness and decision making. There were 29 impaired driving crashes between 2020-2024, three of which resulted in major injuries and three of which resulted in minor injuries.

9. RECOMMENDATIONS
The following sections provide more information on potential engineering and non-infrastructure safety countermeasures that may address conditions that were observed to contribute to crash activity in the Town.

9.1. Engineering Countermeasures
The following sections contain a description of Crash Modification Factors (CMFs) and Crash Reduction Factors (CRFs) associated with the engineering countermeasures toolbox.

9.1.1. Crash Modification Factors
When identifying potential systemic safety improvements, it is important to look at CMFs for the proposed improvements. The CMF Method is found in Part D of the HSM. CMFs are defined as the ratio of effectiveness of one condition in comparison to another condition and represent the relative change in crash frequency due to a change in one specific condition. In other words, a CMF is a multiplicative factor used to compute the expected number of crashes after implementing a given countermeasure at a specific site. Countermeasures with CMFs less than one are expected to reduce crashes if applied, while those countermeasures with CMFs greater than one are expected to increase crashes. Figure 21 illustrates the definition of CMFs.

Figure 21 — CMF Calculation
A Crash Reduction Factor (CRF) is similar to a CMF but stated in different terms. A CRF is defined as a percentage of crash reduction that might be expected after the implementation of a given countermeasure at a specific site. In application, the higher a CRF value is, the more effective the countermeasure is at preventing crashes. Figure 22 shows how a CRF is calculated in relationship to a CMF.

Figure 22 — CRF Calculation
The CMF Method is used to calculate the expected number of crashes by taking the observed number of crashes and multiplying those crashes by the applicable CMF for the proposed countermeasure. It is recommended that CMFs be applied to a minimum of three years of crash

Town of Mammoth Lakes SS4A Safety Action Plan 46 March 2026 data for urban and suburban sites and five years of crash data for a rural site. Figure 23 is a sample calculation of the CMF method with one CMF being applied to a particular site for a single year.

Figure 23 — CMF Method Sample Calculation
Caution should be used in the selection of appropriate CMFs. The following guidance should be considered when selecting CMFs for predictive crash analysis:
▪CMFs should be selected from the HSM Part D, the LRSM, or from the FHWA CMF Clearinghouse website (http://www.cmfclearinghouse.org). ▪ Read the countermeasure abstract to determine if the CMF is applicable to the proposed improvement.
▪ Only CMFs with a four-star rating or higher should be considered for use in analysis. ▪ Be sure the selected CMF is applicable to the set of crash data being used for analysis. Some CMFs may only be applicable as a subset of the crash data. ▪ The application of multiple CMFs can overestimate the expected crash reduction. Unless each CMF addresses independent crash types, multiple CMFs should not be used. It is suggested that no more than three independent CMFs be applied to a particular site.

The countermeasures proposed in this SAP were chosen because of their effectiveness in reducing crashes, especially those most commonly occurring in the Town.

9.1.2. Engineering Countermeasures Toolbox
The systemic improvements identified as most likely effective to be for the Town of Mammoth Lakes are listed in Table 6, and include a wide range of countermeasures that can be implemented in phases where appropriate. Many of these proposed countermeasures have already been implemented in the Town, including but not limited to pedestrian countdown signal heads, conversion of stop-controlled intersections to roundabouts, and installation of retro-reflective backplates on traffic signal heads.

The CMF indicates how effective the countermeasure is at reducing crashes. CMFs and CRFs have been provided for reference to aid the Town of Mammoth Lakes in understanding potential reductions from crashes by different countermeasures. Caltrans funding levels for each countermeasure are also provided to aid the Town in determining what the local match would likely be if the Town were to pursue grant funding. Most countermeasures are eligible for Caltrans funding up to 90%, though some are lower. Some improvements in the toolbox (such as installing a raised intersection) do not have a crash reduction factor listed; while these improvements are recognized to be useful traffic calming treatments, they do not have sufficient studies yet to determine the exact benefit.

o Install advance stop bars and high-visibility crosswalks o If it would not interfere with snow plow operations, install a raised median on the intersection approaches

Town of Mammoth Lakes SS4A Safety Action Plan 51 March 2026

3. Meridian Boulevard and Sierra Park Road [near-term]
o Replace stop signs facing Sierra Park Road with larger; install retroreflective strips on stop sign posts.
o Install advanced stop bars on all intersection approaches with crosswalks; replace existing crosswalks with high-visibility crosswalks.
o Install centerline on the south leg of the intersection. o Install pavement legends on all approaches.
o Install a High Friction Surface Treatment on intersection approaches. o Install green conflict zone bike lane striping on Meridian Boulevard. o Complete an Intersection Safety and Operational Assessment Process (ISOAP) and install a roundabout.

4. Minaret Road (Horizontal curves located between Main Street and the Earthquake Fault access road). It is understood that Caltrans has programed a project focused on Highway 203 through its State Highway Operation and Protection Program (SHOPP). The Town requests that the following safety improvements be incorporated into Caltrans’ project along the corridor [near-term]:
o High Friction Surface Treatment
o Centerline Rumble Strips

5. Systemic improvements at unsignalized intersections along the following corridors: Old Mammoth Road, Sierra Park Road, Minaret Road (south of Main Street), and Meridian Road.

The recommended improvements include [near-term]:
o Install larger/retroreflective stop signs and retroreflective strips on stop sign posts. o Install stop bars in advance of crosswalks, and restripe crosswalks with high-visibility continental striping (or similar).

Road user data was obtained from ReplicaHQ5for the Town of Mammoth Lakes. Approximately 11% of persons who travel within the Town of Mammoth Lakes have a household income of $25K or less; an additional 9.9% have an annual household income of less than $50K (Figure 24). The safety improvements identified at the case study locations and proposed in the safety countermeasure toolbox will benefit these low income households.

9.1.4. Strategic Safety Projects
During coordination with the stakeholder group and public engagement additional locations and safety improvements were identified, beyond those included in the case study locations. While not all of these locations were highlighted in the data analysis section of the report, this SAP recognizes the significance of these locations and has incorporated recommended actions into this document.

1. E-Bike Safety Town-wide and along the Lake Mary Road multi-use path (MUP) [near-term] o It is recommended that the Town adopt the following ordinances in the Town of Mammoth Lakes Municipal Code for e-bikes:
▪ Duplication of California Vehicle Code to allow for the Community Service Officers to perform enforcement alongside Mammoth PD.
▪ Enforcement of speed limits on MUPs, requiring that E-Bike operators must use helmets.
▪ Consider temporarily impounding E-bikes belonging to habitual violators. o It is recommended that the Town adopt the following ordinances in the Town of Mammoth Lakes Municipal Code for local e-bikes users:
▪ Consider implementing a Bike Safety License for kids to ride e-bikes. ▪ Implement a “bicycle safety test” within the online reservation of all e-bikes used in Town.
o It is recommended that the Town adopt the following ordinances in the Town of Mammoth Lakes Municipal Code for e-bikes users who are visiting the Town for a short duration:
▪ Implement a “bicycle safety test” and receive a discount at a local business for completing.
▪ Consider incorporating technology to reduce speed of e-bikes rented in the Town if riding on a facility that the e-bike shouldn’t be on

2. Canyon Lodge Area [near-term]
o It is understood that during the snow season drivers will park their vehicles in noparking zones along Rainbow Ln. This is a critical route for emergency response vehicles responding to calls originating from the snow area. The Town has considered options to prevent drivers from parking in this restricted area. Modifications to enforcement include $350 fines and towing violating vehicles to a new impound lot.

The Town also eliminated parking on both sides of the one-way section of Rainbow Ln.

3. Meridian Boulevard and Minaret Road Roundabout [near-term] o The traffic signal at the intersection has been operating in recall mode (flashing red) due to a lack of required equipment. It is recommended that a roundabout be installed at the intersection to provide improved safety performance and operations.

4. Minaret Road Multi-Use Path (MUP) [near-term]
o Cyclists currently lack a clear route from areas north of Main Street to locations in southern Mammoth Lakes, such as the elementary school or the library. The construction of a MUP along Minaret Road would provide enhanced safety and connectivity for locals and tourists alike.

5. Meridian Boulevard Road Diet [mid-term]

Town of Mammoth Lakes SS4A Safety Action Plan 54 March 2026 o A road diet was completed for Meridian Boulevard between Minaret Road and Old Mammoth Road as part of a safe routes to school project. It is recommended that a similar treatment be applied to Meridian Boulevard between Eagle Lodge and Minaret Road. Consider an enhanced pedestrian crossing across Meridian Boulevard between Villa Vista Dr and the Meadow Ridge driveway.

6. Sight distance at MUP intersections [near-term]
o It is recommended that slopes/embankments be cut back on the MUP approaches to intersections to improve sight distance. Locations include (but are not limited to) the respective intersections of the eastern Middle School Driveway and Commerce Drive with the Town’s MUP system.

7. Main Street and Mountain Road [near-term]
o It is recommended that a pedestrian crossing be installed at this intersection. This will provide pedestrians with an additional crossing location and with improved safety across Main Street.

8. Recessed Pavement Markings [mid-term]
o Other jurisdictions in California which experience significant snowfall (such as Truckee and Tuolumne County) have implemented recessed thermoplastic pavement striping and pavement markers. Tuolumne County was awarded HSIP funding in Cycle 12 for recessed pavement markings. It is recommended that the Town pilot recessed pavement markings using grant funding and if successful, implement more widely across the Town.

The approximate locations of the strategic safety projects are presented in Figure 26.

9.2. Non-Infrastructure Countermeasures
The National Highway Traffic Safety Administration (NHTSA) Countermeasures that Work, Ninth Edition, is a reference to assist safety stakeholders in selecting effective, science-based noninfrastructure traffic safety countermeasures for major highway safety problem areas. While many of the countermeasures are more appropriate to apply at the state-level or require legislative modifications to implement, Table 9 contains countermeasures that have demonstrated effectiveness and could be applied at the Town level. Note that while there are several other noninfrastructure countermeasures available, only those which have an effectiveness rating of four stars or higher are presented. Access to Drug Recognition Experts (DREs) and Advanced Roadside Impaired Driving Enforcement (ARIDE) training for law enforcement is not included in the document but are countermeasures that could also be considered for the Town.

10. EVALUATION AND IMPLEMENTATION

10.1. Evaluation
The success of the SAP can be evaluated using the general process outlined below. This process can be useful to monitor progress towards implementation of safety improvement projects and strategies, and to determine when updates to the SAP should be considered. ▪ Law enforcement continues monitoring and recording of traffic incidents on local roadways. ▪ Conduct frequent progress meetings (annually or quarterly) between Town staff and a working group (i.e. traffic safety committee) to review the latest crash data, including assessing the effectiveness of safety countermeasures implemented, discussing ongoing traffic safety challenges, and tracking progress on plan implementation. ▪ Maintain a list of focus/priority areas where there are transportation safety concerns based on review of crash data. The list of priority and/or top crash locations can be updated as an outcome of review of updated crash data and trends.
▪ Perform an update to the plan after no more than five years. It is recommended that updates to the SAP be approved by TownCouncil and made available to the public in accordance with Caltrans’ Local Roadway Safety Plan guidance.

10.2. Implementation
Implementation of the SAP can be accomplished through development and implementation of safety improvement projects and strategies, the establishment of new/updated policies and programs, and development/strengthening of relationships with stakeholders.

With regard to projects, the following section identifies potential focus areas for the Town in the nearto-mid-term.

10.2.1. Near- and Mid-Term Focus Areas
The opportunities identified in this SAP provide more of the systemic countermeasures that can be applied within the Town. Over the next three to five years, it is recommended that the Town concentrate its efforts on the following emphasis areas:

1. Aggressive driving

2. Lane departures and hit -object crashes related to snowy/icy conditions

3. Vulnerable Road Users (Pedestrians, Bicyclists, and E-Bikes)

4. Unsignalized Intersections
Analysis conducted at the Town-wide level indicated that these factors were some of the most frequent influences contributing to crashes within the Town. The countermeasure opportunities previously discussed in this reportfor both systemic and project-specific improvements can be used as a basis for developing projects at locations where addressing these focus areas would be of the most benefit. Projects that address these focused areas can be developed with a high benefit-tocost ratio (by applying Town-wide crash rates), allowing competitive projects to be developed even at sites with little to no direct crash history, but with conditions that might contribute to future crashes.

Town of Mammoth Lakes SS4A Safety Action Plan 60 March 2026

10.3. Funding
Competitive funding resources are available to assist in the development and implementation of safety projects in the Town of Mammoth Lakes. The Town should continue to seek available funding and grant opportunities from local, state, and federal resources to accelerate their ability to implement safety improvements throughout the Town of Mammoth Lakes. The following is a highlevel introduction into some of the main funding programs and grants for which the Town can apply.

10.3.1. Highway Safety Improvement Program (HSIP)
The HSIP is a Federal program housed under Fixing America’s Surface Transportation (FAST) Act. This program apportions funding as a lump sum for each state, which is then divided among apportioned programs. These flexible funds can be used for projects to preserve or improve safety conditions and performance on any Federal-aid highway, bridge projects on any public road, facilities for nonmotorized transportation, and other project types. Safety improvement projects eligible for this funding include:
▪ New or upgraded traffic signals
▪ Upgraded guard rails
▪ Pedestrian warning flashing beacons
▪ Marked crosswalks
California’s local HSIP focuses on infrastructure projects with national recognized crash reduction factors. Normally the HSIP call-for-projects is made at an interval of one to two years. The applicant must be a city, a county, or a tribal government federally recognized within the State of California.

Additional information regarding this program at the Federal level can be found online at:
https://safety.fhwa.dot.gov/hsip/. California specific HSIP information – including dates for upcoming call for projects - can be found at: http://www.dot.ca.gov/hq/LocalPrograms/hsip.html.

10.3.2. Safe Streets and Roads for All (SS4A)
The SS4A Grant Program is a federal program established by the Bipartisan Infrastructure Law. A total of $5 billion is available from 2022-2026 in the form of planning grants and implementation grants. Grant applications for projects that implement the Safe Systems Approach, such as those related to speed management, improvements in underserved communities, and vulnerable road users, are encouraged. Implementation grant projects must be identified in an applicant’s qualifying Safety Action Plan. The SS4A Self-Certification Eligibility Worksheet describes the required elements of an Action Plan and can be accessed at: https://www.transportation.gov/sites/dot.gov/files/2024- 02/SS4A-FY24-Self-Certification-Worksheet.pdf.

Additional information about implementation grants can be found at:
https://www.transportation.gov/grants/ss4a/implementation-grants.

10.3.3. Caltrans Active Transportation Program (ATP)
Caltrans Active Transportation Program (ATP) is a statewide funding program, created in 2013, consolidating several federal and state programs. The ATP funds projects that encourage increased mode share for walking and bicycling, improve mobility and safety for non-motorized users, enhance public health, and decrease greenhouse gas emissions. Projects eligible for this funding include:

Town of Mammoth Lakes SS4A Safety Action Plan 61 March 2026 ▪ Bicycle and pedestrian infrastructure projects
▪ Bicycle and pedestrian planning projects (e.g. safe routes to school) ▪ Non-infrastructure programs (education and enforcement) This program funding is provided annually. The ATP call for projects typically comes out in the spring.

Information on this program and cycles can be found online at:
http://www.dot.ca.gov/hq/LocalPrograms/atp/.

10.3.4. State Transportation Improvement Program (STIP) The STIP provides state and federal gas tax money for improvements both on and off the state highway system. STIP programming occurs every two years. The programming cycle begins with the release of a proposed fund estimate, followed by California Transportation Commission (CTC) adoption of the fund estimate. The fund estimate serves to identify the amount of new funds available for the programming of transportation projects. Once the fund estimate is adopted, Caltrans and the regional planning agencies prepare transportation improvement plans for submittal. Caltrans prepares the Interregional Transportation Improvement Program (ITIP) using Interregional Improvement Program (IIP) funds, and regional agencies prepare Regional Transportation Improvement Programs (RTIPs) using Regional Improvement Program (RIP) funds.

The STIP is then adopted by the CTC.

10.3.5. California SB 1
SB 1 is a landmark transportation investment to rebuild California by fixing neighborhood streets, freeways, and bridges in communities across California and targeting funds toward transit and congested trade and commute corridor improvements.

California’s state-maintained transportation infrastructure will receive roughly half of SB 1 revenue:
$26 billion. The other half will go to local roads, transit agencies, and an expansion of the state’s growing network of pedestrian and cycle routes. Each year, this new funding will be used to tackle deferred maintenance needs both on the state highway system and the local road system, including:
▪ Bike and Pedestrian Projects: $100 million
o This will go to cities, counties and regional transportation agencies to build or convert more bike paths, crosswalks and sidewalks. It is a significant increase in funding for these projects through the ATP.
▪ Local Planning Grants: $25 million

10.3.6. California OTS Grants
This program has funding for projects related to traffic safety, including transportation safety education and encouragement activities. Grant applications must be supported by local crash data (such as the data analyzed in this SAP) and must relate to the following priority program areas:
▪ Alcohol Impaired Driving
▪ Distracted Driving
▪ Drug-Impaired Emergency Medical
Services
▪ Motorcycle Safety
▪ Occupant Protection
▪ Pedestrian and Bicycle Safety
▪ Police Traffic Services
▪ Public Relations, Advertising, and
Marketing Program
▪ Roadway Safety and Traffic Records

Town of Mammoth Lakes SS4A Safety Action Plan 62 March 2026

11. NEXT STEPS
The Town has completed this SAP to guide the process of future transportation safety improvements for years to come. This report also provides the Town with an opportunity to share how crash trends have changed during the Covid-19 Pandemic and in the years following. The data-driven analysis process identified crash types, related primary crash factors, and locations of crashes. Also, as part of this process, emphasis areas were identified to inform and guide further safety evaluation of the Town’s transportation network. These emphasis areas will guide corridor improvements, education programs, and capital improvements for the Town.

Using the analyzed data and outputs from this SAP, the Town can:
▪ Apply for HSIP Cycle 13 and the final round of SS4A funding to implement infrastructure improvements throughout the Town
▪ Actively seek other funding opportunities to improve safety for all modal users ▪ Collaborate with established stakeholder, safety partners, and neighboring municipalities as improvements are made to create a cohesive transportation network ▪ Iteratively evaluate existing and proposed transportation safety programs and capital improvements to design a safer transportation network in the Town

Davison Road John Muir Road Cars are constantly sliding down Davison in the winter and it creates an extremely dangerous situation. There are also tourists constantly skiing and snowboaRoading down the road whenever there’s snow on it, and combined with out of control cars, it’s incredibly dangerous. We need serious police enforcement here of no riding on the roads and they need to use an actual gate at the top of the road to close it. When they just build a snow wall, people just drive straight through the snow wall to break it down.

The road sees many bikers, runners and walkers. Who often becomes issues for vehicles and the trolley as the road is not big enough for two directions of travel and pedestrians. This could be trialed through a few select dates to see if it increases pedestrian/bike usage of around Lake Mary Road.

More signage and enforcement for no parking on north side of Lakeview. In the winter people start parking on both sides and the travel lane gets very narrow, especially when you take into account the pedestrians walking up and down from the Canyon ski lift to get to their cars or condos
Website
Lakeview Blvd near Canyon Ski Lift No, I don’t think more signage will be helpful. The parking needs to be strictly enforced. Every day that Canyon is open, cars are parked on both sides of the road and it becomes a one lane road and it’s very dangerous, especially with people walking everywhere.

Main St Alpine Cir I agree that at least one pedestrian crossing should be between the post office and the Mammoth Village.

Also traffic coming up the hill on Lakeview Road don’t realize they don’t have to stop but will anyway at the top of the hill before turning onto Lakeview Blvd, which in winter is a hazard since the hill can get icy. Maybe extra signage about which traffic does/does not have to stop would help clarify for drivers.

Now that the new Dog Park has opened across from the Trails community, there has been a noticeable increase in foot traffic crossing Meridian. Vehicles frequently travel at speeds of 45 mph or higher, making it difficult and potentially dangerous for pedestrians to cross safely.

Installing a crosswalk in this area would greatly improve safety for both residents and visitors using the Dog Park.

This is perhaps the most dangerous crosswalk in all of Mammoth. Kids are flying down the path on bikes and parents are pulling in to drop off while other cars are stuck behind them in the middle of the road. The solution is to widen eastbound section of the road to make a long turn lane. Of course a tunnel or overpass for pedestrians would work as-well but much more expensive.

APPENDIX B

SUMMARY OF PROGRAMS, POLICIES AND PLANS

Town of Mammoth Lakes SS4A Safety Action Plan Appendix C (i) March 2026 Summary of Programs, Policies, and Practices for the Town of Mammoth Lakes Topic Current Status Implement or Enhance
Complete Streets
Policy
The Town has identified complete
streets principles in its General Plan. 6
The Town has several plans and
projects that prioritize the
implementation of complete streets,
such as the Walk, Bike, Ride plan
which provides a framework to
improve mobility in the region without
the use of private automobiles.7
It is recommended that the Town
continue to implement projects and
develop design standards consistent
with its Complete Street Policy, while
accounting for seasonal variations and
new micromobility modes.

Traffic Impact
Fees
While the Town of Mammoth Lakes
does not have direct Traffic Impact
fees, the development impact fees DIF
includes vehicle circulation and
multi-modal circulation components
to fund traffic infrastructure. Fees are
updated annually and reviewed by the
Town Council and implemented via
municipal code and Council
resolutions. Occasionally, the Town
temporarily waives or reduces these
fees under Council discretion.8
A percentage of the revenue generated
from collecting DIF’s should be
allocated to traffic safety efforts,
particularly those which may be
included in the CIP. This ensures that
growth pays its fair share for increased
transportation demand, supports the
Town’s Complete Streets and climate
goals, and enhances eligibility for state
and federal transportation grants.

Program for
Reviewing Crash
Activity
The Mammoth Lakes Police
Department (PD) and public works
staff investigate collision incidents.

However, there is not currently a
formal in-house crash review board.

The PD maintains a database and
individual Traffic Collision Reports for
crashes which are available to
involved parties after report
processing (~10 days)9.

It is recommended that the Town sets
up a formal program and/or working
group for reviewing crash activity at a
fixed time interval (i.e. annually);
Update crash database for future LRSP
analyses & updates.

Crossroads
Database
Updates
Mammoth Lakes PD maintains a local
crash database which includes
crashes on CA-203.

It is recommended that the Town
continue its data collection efforts and
consider coordinating with additional
vendors to ensure the quality and
accurate geocoding of crashes, and
near-miss data collection. Coordinate
with Town PD to ensure that propertydamage only crashes are recorded.

Traffic Safety
Education
The Town of Mammoth Lakes has
supported traffic safety education
through initiatives such as the “Every
15 Minutes” DUI awareness program
for teens10, CHP’s “Start Smart” driver
workshops11, and community
outreach on bicycle laws and safety.

The PD has implemented speedmonitoring radar signs, hosted car seat inspection events for families,
and participated in safety fairs to
promote responsible road use. These
efforts reflect the Town’s commitment
to improving traffic safety through
education and community
engagement. 12,
13 ,
14 It is recommended that the Town
considers developing a permanent,
easy-to-navigate webpage dedicated to
traffic safety education. This resource
hub could include information on
pedestrian and bicycle safety, right of
way on Multi-use paths (MUPs), winter
and extreme weather driving best
practices, and key local traffic laws. To
ensure accessibility for all community
members and visitors, the webpage
should offer multilingual resources and
include interactive features such as
maps of safe school routes and trail
regulations. Additionally, the page
could provide seasonal safety updates,
particularly during snowstorms,
holiday traffic peaks, or large
community events and can be
promoted through the Town’s social
media channels and community
newsletters to maximize visibility and
public engagement.

Safe Routes to
School Funding
The town has completed school safety
assessments15 using grants from
Caltrans16, but does not have a
consolidated safe routes to school
plan or dedicated funding source.

It is recommended that the Town
continues applying for SRTS grants for
additional studies or further sidewalk
improvements to and from schools.

Consider dedicating funding towards
annual SRTS improvements.

Transit Vehicles
Accommodation
of Bicycles
Mammoth Lakes public transit allows
bikes for the majority of its services.

ESTA buses and trolleys are equipped
with bikes track that can
accommodate most standard
bicycles. More specifically, the
Mammoth Lakes Trolley designed for
accessing the Lakes Basin features a
bike trailer, allowing cyclists to
transport their bikes easily while they
ride to their desired destination. And
the MAS Bike Shuttle is a dedicated
service that operates daily from The
Village to the Mammoth Bike Park,
providing easy access for cyclists.

Mammoth Lakes is already
accommodating cyclists on their
transit systems, some improvements
to consider could be real-time bike
rack availability on bus/shuttles,
expanding rack compatibility for more
types of bikes such as E-Bikes, and
installing secure bike lockers or racks
at major transit hubs.

Sobriety /
Seatbelt Checks
Mammoth Lakes PD conducts sobriety
checkpoints. 17
It is recommended that the Town
Traffic division coordinates with the PD
in planning and implementing sobriety
and seatbelt checks such as
determining areas with high instances
of DUI or seatbelt violations and
creating high saturation enforcement
campaigns focused on these areas.

Enforcement on
Bicycle Rules
E-bikes are permitted on paved mixeduse paths (MUPs) but with restrictions. A 15-mph speed limit is in
effect on MUPs, and riders are
expected to yield to pedestrians and
be respectful of other users. Cyclists
are expected to follow the rules of the
road, including stopping at red lights
and stop signs. The Mammoth Lakes
PD can issue citations for violations of
cycling rules, particularly those
related to e-bike usage on MUPs.18
It is recommended that the Town adopt
the following ordinances in the Town
Municipal Code for e-bikes:
-Duplication of California Vehicle Code
to allow for the Community Service
Officers to perform enforcement
alongside Mammoth PD.
-Enforcement of speed limits on MUPs,
requiring that E-Bike operators must
use helmets.
-Consider temporarily impounding Ebikes belonging to habitual violators. -Consider implementing a Bike Safety
License for kids to ride e-bikes.
-Implement a “bicycle safety test”
within the online reservation of all ebikes used in Town. -Implement a “bicycle safety test” and
receive a discount at a local business
for completing.
-Consider incorporating technology to
reduce speed of e-bikes rented in the
Town if riding on a facility that the e-bike
shouldn’t be on

and enhances communication during
snow events, road closures, and
special events.20
Continue to coordinate with Adjacent
Jurisdictions and state agencies. Seek
OTS funding for additional enforcement
at locations with high crash frequency
and history of driver behavior related
crashes (i.e. speeding, signal and stop
sign violations), including locations
at/near jurisdictional boundaries.

Traffic Calming
Policies
The Town of Mammoth Lakes has a
Traffic Management Plan. The Town
has implemented traffic calming
policies that include signage and
striping, “streetscaping”, and
deploying traffic control personnel
during busy days/events to moderate
areas burdened with high traffic
volumes. The town is also looking to
implement more permanent traffic
control measures such as traffic
circles and speed humps.21
Continue to implement and enforce
their traffic calming policies. It is
recommended that the Town take a
zone or neighborhood-based approach
to promoting slower speeds and
enhance vulnerable road user safety on
local roads.

Speed Limits
The Town of Mammoth Lakes
determines and sets speed limits
based on speed surveys and roadway
geometry and classification.22
Continue to update as required by
California Vehicle Code; Exercise
context-based flexibility offered under
Assembly Bill 43.

Traffic Safety
Audit Program
The Town of Mammoth Lakes currently
does not have a traffic safety audit
program.

It is recommended that the Town
implements a traffic safety audit
program to regularly (i.e. annually)
review crash data and respond to
community feedback regarding traffic
safety challenges.

Use of overlays,
specific plans,
redevelopment
areas to
encourage infill
development to
reduce VMT
Mammoth Lakes has adopted and
implemented multiple overlay
districts, specific plans, and
master-planned redevelopment zones
such as Clearwater, North Village, and
The Parcel to facilitate compact,
mixed-use infill, supported by
streamlined procedures, parking
strategies, housing variety, and transit
integration. These measures align
directly with regional VMT reduction
policies and demonstrate active local
implementation.29 30 31
The Town can further institutionalize
incentives, modernize zoning and
permitting, and target infrastructure
investments that directly support infill
development in transit-rich areas. Also
identify areas where infill development
will require safety improvements;
Coordinate with County to ensure
connectivity and continuation of safety
amenities with other municipalities.

Transportation
Demand
Management
Policies/Programs
Mammoth Lakes has a solid TDM
foundation such as free transit,
vanpools, park-and-rides, planning
studies, and VMT policies that
significantly reduce vehicle demand.32
The Town could finalize mobility hub
plans, extend service operations and
amenities, modernize parking
strategies, and leverage digital tools
and employer partnerships for more
impactful TDM outcomes.
