BACKGROUND
On July 13, 2010, the City Council adopted a citywide Speed Hump/Cushion Program. The
program established procedures and criteria for the installation of speed humps/cushions on
residential streets. Since the adoption of the program, no community has installed speed
humps/cushions on any residential street.

City staff has completed several traffic studies at the request of various development home
owner associations and community groups. These traffic studies have concluded that the current
requirement of a minimum Average Daily Traffic (ADT) volume of 2,000 vehicles should be
reduced to 1,500 vehicles as several residential streets fall just short of the required threshold,
while meeting all other criteria. The traffic studies also noted a small percentage of local
residential streets that have a history of traffic collisions. In addition, these residential streets
experience higher speeds and volumes.
For these reasons, staff is recommending to amend the existing Speed Hump/Cushion Program to
include the installation of speed humps/cushions on residential streets experiencing traffic
collisions, while meeting all other criteria as identified in the current program. Staff has
identified three residential streets with a history of traffic collisions and meet the minimum
criteria established in the current citywide Speed Hump/Cushion Program. The streets are Abelia
Road, Thompson Ranch Drive, and Pamplico Drive. The installation of speed cushions will
enhance traffic safety within these neighborhoods. Staff sent letters to residents residing along
Abelia Road and 70 percent of the responses supported the installation of speed cushions on the
street. Staff has also received a verified petition from residents along Thompson Ranch Drive
indicating over 67 percent of the residents fronting that street support the installation of speed
cushions. Staff has had several residents along Pamplico Drive indicate that they support the
installation of speed cushions along their street. However, there have been no formal surveys
completed for affected residents. Therefore, prior to the installation of speed cushions along
Pamplico Drive, staff will complete a survey of affected residents and will move forward with
the installation should the results support the project.
Upon approval by the City Council, City staff will proceed with completing the necessary
resident survey on Pamplico Drive and order the necessary supplies to install the speed cushions
along the three proposed streets. The speed cushions will be a sole source order from Traffic
Logix, Inc. of Spring Valley, New York. This product was used successfully on Dorothy Street,
Ermine Street, and Benz Road/Alaminos Drive in the past, and City staff is familiar with the
installation process. In addition, by ordering speed cushions from Traffic Logix, Inc., the City
can ensure product consistency citywide, which will aid in maintenance and material inventory.
Staff anticipates costs will not exceed $200,000 for the purchase and installation of the speed
cushions on Abelia Road, Thompson Ranch Drive, and Pamplico Drive. The cost to purchase the
speed cushions is $120,000, the contract to install the speed cushions is estimated at $60,000
(including project management costs) and the remaining $20,000 will be used as a contingency
to cover the costs of incidental materials and equipment, as needed. Installation of all speed
cushions is anticipated to be completed by the end of the 2018 calendar year.
ALTERNATIVE ACTION
Other action as determined by the City Council.
FISCAL IMPACT
Upon approval of the recommended actions, revenue and expenditure budget accounts will be
adjusted accordingly. Adequate funds will be available to provide for all project related costs.
