17.112.050 Handicapped access.

A. Location. Accessible parking spaces required for a particular building shall be located on the shortest accessible route of travel from adjacent parking to an accessible building entrance. In parking facilities that do not serve a particular building, accessible parking shall be located on the shortest accessible route of travel to an accessible pedestrian entrance of the parking facility. In buildings with multiple accessible entrances with adjacent parking, accessible parking spaces shall be dispersed and located closest to the accessible entrances. Accessible parking spaces shall be provided on level parking surfaces with a slope not exceeding 1:50 (2%) in all directions.

B. Accessible Routes. All accessible routes shall not be less than three feet (3') in width and provided from the handicap parking space(s) to the entry of the land use or structure. Handicap parking aisles may be used as an access route.

C. Curb Ramp. A curb ramp shall be provided wherever an access route crosses a curb. The curb ramp shall be not less than thirty-six (36) inches in width, exclusive of flared sides with a slope not exceeding 1:12. The ramp flared sides shall not exceed a slope of 1:10.

All curb ramps shall have a detectable warning surface on them covering the full width and depth of the curb ramp. A detectable warning surface consists of raised truncated domes with a diameter of .9" (23 mm), a height of .2" (5 mm), and a center-to-center spacing of 2.35" (60 mm) and shall contrast visually with adjoining surfaces (per ADAAG).

D. Signage. Accessible parking spaces shall be designated as reserved by a sign showing the symbol of accessibility. Spaces complying with Section 17.112.030(C)(4) shall have an additional sign "Van Accessible" mounted below the symbol of accessibility. Such signs shall be located so they cannot be obscured by a vehicle parked in the space. The sign shall be an R7-8 sign as described in the Manual on Uniform Traffic Control Devices (as shown below). The bumper stop or curb head shall be painted with the standard accessibility blue color. The painted accessibility symbol shall not be required; however, if the symbol is painted, it shall conform to the International Symbol of Accessibility Proportions, Section 17.112.050(G) below.

E. Vertical Clearance. Minimum vertical clearance of one hundred fourteen (114) inches (2,895 mm) at accessible passenger loading zones and along at least one vehicle access route to such areas from site entrance(s) and exit(s) shall be provided. Van accessible spaces shall be provided a minimum vertical clearance of ninety-eight (98) inches (2,490 mm) at the parking space and along at least one vehicle access route to such spaces from site entrance(s) and exit(s).

F. Passenger Loading Zones. If provided, passenger loading zones shall provide an access aisle at least sixty (60) inches (1,525 mm) wide and twenty (20) feet (240 inches) (6,100 mm) long adjacent and parallel to the vehicle pull-up space. If there are curbs between the access aisle and the vehicle pull-up space, then a curb ramp complying with Section 17.112.050(C) shall be provided. Vehicle standing spaces and access aisles shall be level with surface slopes not exceeding 1:50 (2%) in all directions.
