Classification of Facilities.

(1)

Short-term bicycle parking means a stand or other device constructed so as to enable the user to secure by locking the frame and one wheel of each bicycle parking therein. Racks must be easily usable with both U-locks and cable locks. Racks should support the bikes in a stable upright position so that a bike, if bumped, will not fall or roll down. Racks that support a bicycle primarily by a wheel, such as standard "wire racks," are not acceptable.

Long-term bicycle parking means a locker, or a locked enclosure, or supervised area within a building or weather protected enclosure providing an extra layer of security for bicycles parked therein from theft, vandalism, and weather.

Bicycle parking facilities should be located in highly visible, well lit areas to minimize theft and vandalism.

(2)

Bicycle parking should be located in close proximity to the building's entrance.

(3)

Bicycle parking facilities shall not impede pedestrian or vehicular circulation.

(4)

For long-term bicycle parking areas, hanging racks are not permitted; doubledecker and roll-in racks are acceptable for space saving. Long-term bicycle parking areas are recommended, but not required, to have security cameras.

(5)

For short-term bicycle parking areas, one u-rack is equivalent to two bicycle parking spaces.

(6)

Paving is not required for short-term bicycle parking, but the outside ground surface shall be finished or planted in a way that avoids mud and dust. Racks must be anchored with concrete footings if mounting in unpaved areas.

(7)

All racks shall comply with Association of Pedestrian and Bicycle Professionals guidance.

(8)

Bicycle parking facilities within vehicle parking areas shall be separated by a physical barrier, such as curbs, wheel stops, poles or other similar features, to protect bicycles from damage.

(9)

Bicycle rack spacing shall comply with Association of Pedestrian and Bicycle Professionals guidance and shall be spaced such that they allow cargo bicycles and other alternative bicycle designs as noted in the Association of Pedestrian and Bicycle Professionals guidance to be secured.
