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