§ 19-652. Eligibility requirements.

All of the following criteria must be satisfied for a street to be considered eligible for speed cushion installation. The city reserves the right to change any or all of the criteria if deemed necessary.

(1)

Petition. A petition from the residents that documents that a least seventy-five (75) percent of all households, adjacent to the project street, support their installation.

(2)

Location of the street. The land uses of the properties abutting the street where the speed cushion is proposed must be composed primarily of residential dwellings.

(3)

Operational characteristics of the street.

a.

Speed cushions should only be installed on those roadway facilities functionally classified as "local" streets. These streets generally permit direct access to abutting lands, connect to higher classification streets, offer the lowest level of traffic mobility and deliberately discourage service to through traffic movement. These "local" streets should be residential in nature.

b.

There must be no more than one (1) moving lane of traffic in each direction.

c.

Traffic volumes must be more than five hundred (500) but less than three thousand (3,000) vehicles per day.

d.

Vehicle speeds must exceed the speed criteria.

e.

The street must have a posted or prima facie speed limit of thirty (30) mph or less as determined in accordance with state law.

f.

Speed cushions should not be installed on streets that are defined or used as primary or routine emergency vehicle access routes. Fire and police approval will be required.

g.

The street must not be classified as a major collector or an arterial, as defined by the thoroughfare plan of the city.

(4)

School zones. When the street requesting a speed cushion is abutting a school zone the minimum speed criteria should be lowered from thirty-five (35) mph to thirty (30) mph and the peak twenty (20) mph school speed zone time period should not be taken into consideration when evaluating the speed criteria.

(5)

Geometric characteristics of the street.

a.

The street must have adequate sight distances to safely accommodate the speed cushion as determined by the traffic safety department.

b.

The street must not have curves or grades that prevent safe placement of the speed cushions and where the visibility of the speed cushion is restricted. Speed humps may be located on streets that contain curves and/or grades, but the speed cushion itself should not be located within a significant horizontal curve, on a vertical grade greater than eight (8) percent.

c.

The street must be paved and have curb and gutter. If there are no curbs, a special design must be used to prevent vehicle runarounds and accommodate drainage.
