CITY OF DIAMOND BAR
SPEED HUMP POLICY
Introduction
EXHIBIT "A"
1.1 Speeding on local residential streets has been one of the most frequently mentioned
concerns expressed by residents and one of the most difficult and elusive problems
confronting many cities in California. In the City of Diamond Bar oftentimes the problem
is resolved by enforcement of the speed limits or by installing additional advisory and/or
regulatory signs.
1.2 in addition, residents request the installation of some type of traffic control measure,
such as "speed bumps" or "speed humps" to address the speeding problem in their
neighborhood. A speed bump is an abrupt pavement feature, three to four inches in
height and one to three feet in length at the base. They are commonly installed on
private roadways and shopping centers but are not recommended for use on public
streets. By comparison, a speed hump (see Attachment A, "Speed Hump Standard") is
approximately three inches in height and 12 to 14 feet in length at the base and
therefore is much gentler in configuration without the "jarring" effect of speed bumps.
Only speed humps are eligible for consideration under this policy.
1.3 In an effort to address these concerns, staff and the Traffic and Transportation
Commission have conducted extensive research on how other jurisdictions approach
the issue of speeding on residential streets and have formulated this policy based on
those findings and the City Council has adopted this policy.
General Policy
2.1 Speed humps will only be considered as a last resort to control speeds on local
residential streets, once all other feasible measures/alternative actions have been taken
and have proven ineffective. Local residential streets are defined below.
2.2 It is the policy of the City to require that the criteria set forth below are met prior to
consideration for installing speed humps on any local residential street for the purpose
of controlling speed.
2.3 The City reserves the right to install, alter, or remove any or all speed humps in the
future at its own discretion, based on a determination by the City Engineer that the
action advances, public health, safety or welfare.

Procedure for Resident Initiated Consideration
4.1 The consideration of the installation, modification or removal of speed humps may be
initiated by resident's request in accordance with the following procedures.
1. Any resident may submit a written request to the City Engineer for consideration
of the installation of speed humps. Upon receipt of a written request, if all other
feasible measures/alternative actions have been taken and have proven
ineffective, the City Engineer will then evaluate the street to determine if the
street meets the physical criteria set forth in this policy for the installation of
speed humps.
2. If the street is determined to be eligible for consideration of the installation of
speed humps, the requestor will provide the City Engineer with a petition in
accordance with the requirements listed below.
3. Any resident may submit a written request for consideration of the modification
and/or removal of speed humps. This request shall be accompanied by a
petition in accordance with the requirements listed below.
4. All petitions for consideration of the installation, modification or removal of speed
humps shall be made on the City's petition form (see Attachment B). A separate
petition shall be submitted for each street on which speed hump installation,
modification or removal is being requested. Petition forms can be obtained from
the City's Public Works Division.
5. Each petition to install, modify or remove a speed hump shall contain signatures
representing of at least 67% of the residential properties affected by the
proposed action, in favor of that action. Affected residents are those along the
affected portion of that street (within 114 mile of any speed hump or to the
nearest intersection with a street that allows ingress and egress from the
neighborhood, whichever is further).Each residence/household will only have one
(1) vote. It is the responsibility of the requestor to obtain the necessary
signatures.

failure to meet the requirement. If the petition contains the required number of
signatures in favor of the proposed action, a neighborhood meeting will be scheduled to
discuss the advantages and disadvantages of speed humps. Residents will receive
notification of the meeting two (2) weeks prior to the meeting date.
4.3 Unless the City Engineer receives written withdrawal of signatures within five (5) days
after the neighborhood meeting, and such requests reduce the neighborhood support to
less than 67% of the residential properties affected by the proposed action, the City will
