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

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 Council that the action advances, public
health, safety or welfare.
