Town of Danville
Danville, California
Subject: Issues, Omissions, and Unanswered Questions - Staff Memorandum 3.1 “E-Bike Safety
- Local Ordinance Considerations”
Prepared by: Danville Safety Advocates and E-bike Access
Mayor and Council Members,
We respectfully submit this revised report to address significant issues, omissions, and
unanswered questions arising from Staff Memorandum 3.1, “E-Bike Safety - Local Ordinance
Considerations,” prepared for the May 12, 2026 Town Council Study Session.
Staff Memorandum 3.1 addresses local legal authority, policy options, statewide legislation,
education, enforcement concerns, and park-related recommendations. However, it does not
meaningfully answer several central findings of the Danville Risk Assessment Sidewalk
Operation of Electric Bicycles and High-Powered Electric Motorcycles (February 1, 2026)
Particularly as they relate to residential sidewalks, sidewalk width, predictable conflict points,
local collision evidence, signage, enforcement practicality, and municipal notice.
The most recent local collision data makes this issue more urgent. From January 1, 2025
through April 29, 2026, Danville identified 9 e-bike collisions in approximately 16 months.
At least 7 of those 9 recent collisions involved riders age 16 or younger. The recent pattern
includes severe injuries and recurring conflict locations near major roads, intersections, trail
2
connections, downtown streets, and neighborhood areas. This recent local evidence raises
serious questions about whether continued deferral is an adequate public safety response.
The central issue is not whether the Town has any authority over sidewalks. Staff Memorandum
3.1 acknowledges that the Town’s strongest authority includes Town-controlled infrastructure,
including sidewalks. The unanswered question is why the Town recommends using that
authority in parks, but not on residential sidewalks where the same foreseeable conflicts exist.
We respectfully ask the Council to consider the following issues, omissions, unanswered
questions, and recommended actions before relying on Staff Memorandum 3.1 as a complete
basis for policy decisions.
1. Engineering Unsuitability of Danville Sidewalks
The Risk Assessment concluded that Danville’s typical 4- and 5-foot sidewalks are pedestrian
facilities and do not meet recognized standards for shared use by pedestrians and faster, heavier
motorized devices, including throttle-assisted electric motorcycles commonly called e-motos.
Staff Memorandum 3.1 does not provide a competing engineering analysis or identify an
engineering standard supporting shared use of typical narrow residential sidewalks by
pedestrians and faster electric devices.
Questions:
• What engineering standard is the Town relying on to justify continued motorized
operation on typical 4- and 5-foot residential sidewalks?
• If the Town disagrees with the Risk Assessment’s engineering conclusion, where is the
Town’s competing engineering analysis?
Recommended Council Action:
Direct staff to prepare and return with an ordinance or resolution prohibiting motorized operation
3
of e-bikes, e-motos, electric scooters, and similar motorized devices on narrow pedestrian
sidewalks, unless and until the Town produces a contrary engineering analysis showing such
operation can be accommodated safely. . (See video documentation of e-moto operation on
sidewalks and park paths)

3. Collision Mechanics and Predictable Conflict Points
The Risk Assessment explained that sidewalk operation increases predictable conflict points at
driveways, intersections, ADA ramps, landscaping obstructions, and limited-sight-distance
locations. It further explained that riders on sidewalks often approach motorists from angles,
speeds, and positions drivers do not expect. Staff Memorandum 3.1 refers generally to pedestrian
conflicts and near misses, but it does not analyze these specific crash pathways or explain why
those risks are acceptable.
Questions:
• Why did Staff Memorandum 3.1 not analyze the driveway, intersection, sight-line, and
ADA-ramp conflict points identified in the Risk Assessment?
• What is the Town’s basis for concluding that these predictable collision pathways do not
warrant immediate corrective action?
Recommended Council Action:
Direct staff and the Police Department to identify and map the most foreseeable sidewalk
conflict points, especially driveways, intersections, ADA ramps, and sight -obstructed locations,
and bring forward immediate corrective measures for those locations.
4. Recent Danville Collision Data Shows an Active and
Growing Local Problem
The Risk Assessment relied on Danville-specific collision information and concluded that future
conflicts are foreseeable if faster electric devices continue operating in pedestrian spaces.
Staff Memorandum 3.1 references some Danville collision information, but it does not fully
analyze the most recent local pattern from January 1, 2025 through April 29, 2026.
That recent period is especially important. From 2018 through 2024, Danville had 7 identified e-
bike collisions over seven years. But from 2025 through April 29, 2026, Danville had already
5
identified 9 collisions in approximately 16 months. In 2025 alone, Danville recorded 6
identified collisions, nearly matching the entire total from the prior seven -year period. By April
29, 2026, Danville had already recorded 3 more identified collisions.
The recent age pattern is also significant. From 2025 through April 29, 2026, at least 7 of the 9
recent collisions involved riders age 16 or younger. The reported youth ages include 15, 16,
14, and 12 in 2025, and 14, 16, and 14 in 2026. This shows that the issue increasingly involves
middle-school and high-school-age riders, not only adult commuter or recreational e-bike use.
The injury pattern shows that these are not merely nuisance incidents or minor falls. Across the
identified collision list, 12 of 16 collisions involved some level of reported injury, and 6
involved either fatal or severe injury. During the recent 2025 through April 29, 2026 period,
serious injuries continued to occur, including severe injuries involving riders age 69, 16, 12, and
14.
The 2026 data is especially concerning because it shows the pattern remains active. Danville had
3 identified e-bike collisions by April 29, 2026, only about one-third of the way through the
year. Even without projecting a year-end total, that number shows that the recent collision trend
has not stopped.
The recent locations also show recurring conflict areas, including major roads, intersections, Iron
Horse Trail connections, downtown streets, and neighborhood locations. These include areas
such as San Ramon Valley Boulevard, Crow Canyon Road, Hartz Avenu e, Diablo Road, La
Gonda Way, Railroad Avenue, and neighborhood street locations. This supports the need for a
targeted local review of sidewalks, trail crossings, school routes, downtown streets,
neighborhood cut-through routes, park paths, driveways, and intersections.
Questions:
• Why did Staff Memorandum 3.1 not directly analyze the recent Danville-specific
collision pattern from January 1, 2025 through April 29, 2026?
• How does staff reconcile its recommendation to defer residential sidewalk action with the
fact that Danville identified 9 e-bike collisions in approximately 16 months?
• Why did Staff Memorandum 3.1 not address the recent youth pattern showing that at
least 7 of the 9 recent collisions involved riders age 16 or younger?
• Why did Staff Memorandum 3.1 not address the recent severe-injury pattern involving
both older adults and youth riders?
• Has the Town evaluated whether the recent collision pattern supports immediate targeted
action on Town-controlled sidewalks, park paths, trail crossings, and school routes?
• Will staff provide a complete recent collision summary showing date, location, device
type, rider age, injury severity, and whether each incident occurred on or near a sidewalk,
school, park path, trail crossing, driveway, or intersection?
Recommended Council Action:
Require staff to prepare a focused Danville-specific collision analysis for the period from
6
January 1, 2025 through April 29, 2026 before the Council relies on Staff Memorandum 3.1’s
recommendation to defer residential sidewalk action.
The analysis should identify youth-involved collisions, severe injuries, device types, locations,
school-route connections, trail crossings, sidewalk proximity, and recurring conflict areas. Staff
should then explain whether this recent local evidence supports immediate targeted protections
on Town-controlled infrastructure.

4. Municipal Liability, Notice, and Foreseeability
The Risk Assessment expressly analyzed California Government Code sections 830 through
835.4 and concluded that the Town now has foreseeability, notice, and control regarding the
risks posed by e-bike and e-moto sidewalk operation. Staff Memorandum 3.1 lists the City
Attorney as having reviewed or contributed to the staff memo, but it does not expressly address
the Risk Assessment’s liability analysis, nor does it state whether the Town agrees or disagrees
with the notice, foreseeability, and dangerous-condition concerns raised.
Questions:
• Did the Town Attorney specifically evaluate the Government Code sections 830 through
835.4 analysis contained in the Risk Assessment?
• Does the Town agree or disagree that it has now been placed on notice of foreseeable
risks involving e-bike and e-moto operation on sidewalks and park paths?
• What is the Town’s legal basis for deferring action if it has already received detailed
notice of these risks?

(Photo: E-Moto on the sidewalk, San Ramon Valley Blvd., Danville
Recommended Council Action:
Request a written legal evaluation from the Town Attorney addressing notice, foreseeability,
dangerous-condition exposure, and the legal consequences of deferring corrective action after the
Town has been placed on notice of these risks.)
6. Prompt Corrective Action
The Risk Assessment concluded that the current level of municipal risk is high and that prompt
corrective action is warranted. Staff Memorandum 3.1 recommends a narrower approach: park
ordinance amendments, continued support for state legislation, regional coordination, and
deferral of expanded residential sidewalk restrictions. The memo does not directly explain why
the Risk Assessment’s conclusion requiring prompt local corrective action is incorrect.
Questions:
• Why did Staff Memorandum 3.1 not directly answer the Risk Assessment’s conclusion
that prompt corrective action is required?
• What is the Town’s threshold for action before broader sidewalk restrictions become
necessary and appropriate?
• How many additional near misses, complaints, collisions, or injuries would be required
before the Town acts locally on residential sidewalks?
Recommended Council Action:
Reject continued deferral as the default response and direct staff to return promptly with targeted
local measures that can be implemented now on Town-controlled infrastructure. (See Letter
Signed by 50 Danville Resident)

7. Lawful E-Bikes vs. Throttle-Assisted E-Motos
The Risk Assessment explained that many problematic devices are not traditional bicycles, but
higher-powered electric motorcycles or misclassified electric vehicles that exceed California’s
statutory e-bike limits. Staff Memorandum 3.1 acknowledges that modified and higher-powered
devices exist and that device classifications are difficult to distinguish in the field. However, the
memo still frames much of the issue as e-bike regulation rather than squarely confronting
unlawful or misclassified high-powered motorized operation in pedestrian spaces.
Questions:
• Why does Staff Memorandum 3.1 continue to frame the issue primarily as e-bike
regulation when the Risk Assessment identifies unlawful or misclassified higher -powered
electric motorcycles as a major part of the problem?
• How many of the problem devices observed in Danville are lawful Class 1, 2, or 3 e -
bikes, and how many are misclassified or unlawful e -motos?
• Will the Town develop a practical enforcement distinction between lawful bicycles and
unlawful motorized devices being operated in pedestrian spaces?
• If the police are unable to tell the difference, have they asked the City Attorney, District
Attorney or County Counsel for assistance? What steps do the police usually take when
they are unable to determine the legality of something?

Recommended Council Action:
Direct staff to clearly distinguish lawful Class 1, 2, and 3 e-bikes from unlawful or misclassified
9
higher-powered electric motorcycles, and to draft enforcement language aimed specifically at
unlawful motorized operation in pedestrian spaces. (See Petition with 1,000 Signatures –
Mostly Danville Residents)
8. School-Based and Youth Evidence
The Risk Assessment cited school-area evidence, including observations involving Diablo Vista
Middle School in Danville, and raised concerns about youth operation of higher-powered electric
devices. Staff Memorandum 3.1 discusses youth safety concerns generally and identifies rider
readiness as a central issue, but it does not directly engage with the specific local school-area
evidence raised in the Risk Assessment.
(Table 8 below: Mineta Transportation Institute’s Project 2423 - Exploring Electric Bicycle
Safety Performance Data and Policy Options for California, December 2025, page #65)
Questions:
• Why did Staff Memorandum 3.1 not directly address the Diablo Vista Middle School
evidence discussed in the Risk Assessment?
• What Danville-specific data does the Town have regarding juveniles operating unlawful,
modified, or higher-powered electric devices?
• What specific coordination has occurred with SRVUSD regarding school bike corrals,
device types, parent notice, and school-area enforcement?
10
Recommended Council Action:
Direct staff to gather and present Danville-specific school-area data, including observations near
middle schools, and to coordinate with SRVUSD and law enforcement on immediate youth
safety measures.
9. Location-Based Enforcement
The Risk Assessment explained that a location-based rule is simpler and more enforceable
because officers can act based on observable conduct: motorized operation on a sidewalk, park
path, or pedestrian-only area.
Staff Memorandum 3.1 acknowledges that officers cannot readily determine rider age, device
classification, or modification status, but it does not seriously analyze the simpler location-based
alternative.
(Photo: E-Moto on sidewalk Greenbrook Drive)
Questions:
• Why did Staff Memorandum 3.1 not seriously evaluate a location -based enforcement rule
for sidewalks, park paths, and other pedestrian-priority areas?
• If officers cannot reliably determine device class, wattage, modification status, or rider
age in the field, what is the Town’s objection to a simpler rule based on observable
conduct and location?
• Would a location-based rule be more enforceable than the current behavior-based
standard?
Recommended Council Action:
Direct staff to evaluate and return with a location-based enforcement ordinance focused on
observable conduct: motorized operation on sidewalks, park paths, and pedestrian -priority areas,
rather than relying on field determinations of class, wattage, modif ication status, or age.
11
10. Signage and Notice Deficiencies
The Risk Assessment concluded that the Town has not consistently provided visible notice,
standardized signage, or clear transition warnings in areas where restrictions already exist,
including the business district sidewalk prohibition.
Staff Memorandum 3.1 does not explain whether those concerns are valid, whether signage is
presently adequate, or whether deficient notice may be undermining enforcement.
Questions:
• Why did Staff Memorandum 3.1 not address the signage and notice deficiencies
identified in the Risk Assessment?
• Has the Town evaluated whether inadequate signage is undermining enforcement of
existing ordinances?
• Will the Town conduct a signage audit before concluding that existing ordinances are
sufficient?
Recommended Council Action:
Direct staff to conduct a prompt signage and notice audit and install standardized, visible
warning and restriction signs in all locations where sidewalk or park restrictions apply.
11. Quantified Enforcement Data
Staff Memorandum 3.1 states that the Town has continued enforcement of reckless riding
behavior, including impoundment, and that targeted enforcement near schools and parks has had
limited effectiveness. However, it does not provide the number of citations , warnings, impounds,
repeat violators, parent contacts, or cases involving the business district ordinance or existing
park restrictions. Without that information, the Council cannot determine whether current
ordinances are actually being enforced or whether they are effective.
Questions:
• How many citations, warnings, impounds, repeat contacts, and parent notifications have
there been under the business district sidewalk ordinance and existing park restrictions?
• What specific violations were those actions based on?
• If those numbers are low, is that because violations are rare, or because enforcement is
not being meaningfully carried out?
Recommended Council Action:
Require the Police Department to provide quantified enforcement data, including warnings,
citations, impounds, repeat contacts, parent notifications, and ordinance-specific enforcement
activity, before the Council determines whether current measures are effective.
12
12. Implementation Measures
The Risk Assessment recommended clearer signage, enforcement of existing restrictions,
updates to the Bicycle Master Plan, a near-miss and collision reporting system, and semiannual
review of e-bike and e-moto crashes.
Staff Memorandum 3.1 does not clearly state which of those implementation measures the Town
accepts, rejects, or intends to study further.
Questions:
• Which implementation measures recommended in the Risk Assessment does the Town
intend to adopt, and which does it reject?
• If the Town rejects those recommendations, what is its basis for doing so?
• Will the Town establish a near-miss reporting system and semiannual review of e-bike
and e-moto incidents?
Recommended Council Action:
Direct staff to return with an implementation plan identifying which Risk Assessment
recommendations will be adopted, on what schedule, and with what responsible department.
13. Full Mineta Record
Staff Memorandum 3.1 relies on the Mineta Transportation Institute report as part of the
statewide research and clinical context, but the attachment list identifies the Mineta material as
an executive summary rather than the full report.
The full Mineta report includes additional material on powered bicycle-shaped conveyances,
higher-powered devices, labeling problems, enforcement challenges, and California legal
definitions. Because the full report was not placed before the Council as an attachment, the
Council may not have had the full evidentiary record relevant to the issues raised in the Risk
Assessment.
Questions:
• Why did staff provide only the Mineta executive summary instead of the full report?
• Will the Town place the complete Mineta report into the public record before further
action is taken?
• Will staff identify which specific portions of the full Mineta report support, weaken, or
complicate Staff Memorandum 3.1’s recommendations?
Recommended Council Action:
Require the complete Mineta report and any related supporting materials to be placed in the
public record before further policy decisions are made on this issue.
13
14. Unsupported Comparative Safety Assumption
A central premise of Staff Memorandum 3.1 is that expanding residential sidewalk prohibitions
could move youth riders into vehicle travel lanes, where interactions with vehicles may present a
higher-severity risk.
That is an important concern, but the memo does not provide collision modeling, location-
specific street analysis, local injury comparisons, speed data, or safe-route analysis showing that
continued sidewalk operation is safer overall than a targeted sidewalk prohibition combined with
education, signage, enforcement, and safe-route planning. The memo therefore relies on a
comparative safety assumption that has not been fully supported in the public record.
Questions:
• What evidence supports the conclusion that prohibiting e-bikes and e-motos on
residential sidewalks would increase overall injury risk?
• Did staff analyze which residential streets, school routes, and sidewalk corridors would
be affected by a prohibition?
• Did staff consider a targeted ordinance that prohibits motorized operation on sidewalks
while also identifying safer routes, school-area controls, and education measures?
Recommended Council Action:
Direct staff to provide a written comparative safety analysis before relying on the assumption
that residential sidewalk restrictions would reduce overall safety. That analysis should compare
sidewalk risk, roadway risk, school-route conditions, rider age, device speed, and available safer-
route alternatives.
15. Questions Raised by the Recommendation Section of
Staff Memorandum 3.1
The Recommendation section of Staff Memorandum 3.1 states that many of the Town’s concerns
involve areas governed by state law; that statewide action offers the greatest opportunity to
improve clarity and enforceability; that the Town’s strongest authority lies in regulating behavior
within parks and on Town-controlled infrastructure, including sidewalks; and that the most
effective municipal actions are clear, objective, and enforceable within existing legal authority.
It then recommends advancing the PRAC park recommendation, deferring expansion of
residential sidewalk prohibitions, formally supporting pending state legislation, and continuing
regional coordination and legislative advocacy.
This creates a central unanswered question: if the Town acknowledges that sidewalks are within
its strongest local authority, why is the Town recommending action in parks but deferral on
residential sidewalks?
14
(Photo: E-moto on sidewalk, Brookside Drive)
Questions:
• If the Town’s strongest authority lies in parks and on Town-controlled infrastructure,
including sidewalks, why is the Town deferring broader action on residential sidewalks
instead of acting where it already has local authority?
• If the Town’s stated standard is that the most effective municipal actions are clear,
objective, and enforceable, why was a clear location-based sidewalk rule not seriously
evaluated?
• What exactly does the Town need from the 2026 legislative session before it can act on
residential sidewalk safety under authority it already possesses?
• Why does the Recommendation section propose amending the Parks Ordinance when the
Town already has restrictions on motorized vehicles in parks?
• Before proposing a new Parks Ordinance amendment, did staff evaluate whether the
existing park prohibition has been meaningfully enforced?
• What immediate local safety measures will be implemented while the Town waits for
Sacramento and continues regional coordination?
• If a person is injured during the period of deferral recommended in Staff Memorandum
3.1, what is the Town’s justification for having chosen delay over immediate corrective
action on Town-controlled infrastructure?
• Why did the Recommendation section not explain why the Risk Assessment’s
engineering, enforcement, and liability findings did not justify including residential
sidewalks in the recommended actions?
Recommended Council Action:
Direct staff to return with a revised recommendation that expressly explains why the Town’s
existing authority over sidewalks and parks is not being used more fully now, and what
immediate interim measures will be implemented during any period of legislati ve deferral.
15
Requested Council Action
For these reasons, we respectfully urge the Town Council not to treat deferral as an adequate
response to the safety issues identified in the Risk Assessment.
Before relying on possible future state action, the Council should require a clear public
explanation of why the Town’s existing authority over sidewalks, parks, and Town -controlled
infrastructure is not being used now to address foreseeable conflicts in locations where injury
risk is already known or readily identifiable.
The Council should require staff to reconcile Staff Memorandum 3.1 with the recent local
collision record from January 1, 2025 through April 29, 2026. The evidence shows an active
pattern of e-bike collisions, substantial youth involvement, and serious injury outcomes. Before
the Town defers residential sidewalk action, staff should explain why this recent local pattern
does not justify immediate targeted protections on Town-controlled infrastructure.
At a minimum, the Council should require staff to respond directly to the Risk Assessment’s
findings regarding sidewalk width and engineering suitability, driveway and intersection conflict
points, Danville collision history, enforcement practicality, signage and notice, municipal notice,
and potential liability exposure. If those points cannot be answered persuasively, then the record
supports immediate consideration of targeted local protections rather than continued delay.
Public safety decisions should rest on clear reasoning, direct engagement with the evidence, and
a demonstrated willingness to act where the Town has authority. We respectfully ask the Council
to evaluate this matter on that basis.
