Questions with the current code When it comes to circulation paths and vehicular areas, the current code leaves something to be desired. There is no clear prohibition against an accessible route coinciding with a vehicular traffic area. The definition of “accessible route” includes “crosswalks as vehicular ways,” but the code doesn’t define what a crosswalk is. CBC Section 11B-502.7.1 states that a person who has parked in an accessible parking space shall not be required to travel behind other parking spaces. However, this section does not mention travel behind parked cars for disabled people who have not parked. In my experience, most CASps would agree that an accessible route coinciding with a vehicular area is not a best practice, but it is permitted by the current code. Furthermore, the term “hazardous vehicular area” in CBC Section 11B-247.1.2.5 has been ambiguous and controversial for many years. What constitutes a hazardous vehicular area? I have heard the argument over the years that parking areas are not hazardous due to slow driving speeds. While I generally don’t agree and I believe that opinion is the minority, I can see how the current code could be interpreted that way. Two steps forward To address the questions above, Section 11B-247.1.2.5 will be completely replaced, and a new Section 11B-250.1 will be added to Chapter 11B. These changes will remove the term “hazardous vehicular areas” and require circulation paths contiguous to vehicular traffic to be physically separated from vehicular traffic. Vehicular traffic includes travel through parking facilities, into and out of parking spaces and electric vehicle charging spaces (EVCS), along roadways, driveways and drive aisles. New definitions have also been added for “driveway” and “drive aisle.” There are several exceptions to Section 11B-250.1, which we’ll get to in a few seconds. Nonetheless, this new code language will now more clearly require a separation between circulation paths and vehicular traffic, regardless of whether these areas could be considered non-hazardous. Section 11B-250.1 requires circulation paths contiguous to vehicular traffic to be raised 4 inches minimum above the area where vehicular traffic occurs, with several important exceptions: Section 11B-250.1, Exception 1 Curb ramps and blended transitions with detectable warnings complying with Section 11B-247 may be used to connect raised circulation paths and pedestrian crossings within areas of vehicular traffic. Blended transitions and cut-through medians with detectable warnings complying with Section 11B-247 may be used to connect circulation paths and pedestrian crossings at similar elevations within areas of vehicular traffic. Of course we need some way of transitioning from the raised circulation path into and through the vehicular traffic area. This exception allows for that. It also recognizes that a blended transition or cut-through median may be at similar elevations to the crossing within vehicular traffic areas - what some might call a “flush transition.” Section 11B-250.1, Exception 2 At locations where sidewalks and walks in the public right-of-way cross driveways without yield or stop traffic control, compliance with this section shall not be required. It appears the intent of this exception is to exempt sidewalks from having detectable warnings where there is no official yield or stop traffic control in the public right-of-way. It could indeed be problematic if unofficial traffic control on private property triggered detectable warnings in the public right-of-way. However, the language is not completely clear. Future advisories and/or code amendments from DSA will hopefully provide clarification on this. Section 11B-250.1, Exception 3 At locations where circulation paths cross driveways or drive aisles, circulation paths shall not be required to comply with this section and detectable warnings shall not be permitted. Beyond the crossing where continuation of the circulation path within a parking facility leads immediately to and does not continue beyond only parking spaces complying with Section 11B-502, passenger drop-off and loading zones complying with Section 11B- 503 and electric vehicle charging stations complying with Section 11B-812, the circulation path shall not be required to be raised. Detectable warnings can act as a hindrance to many wheelchair users. We have all seen cases where long strips of detectable warnings were used to demarcate a circulation path within a vehicular area, requiring a wheelchair user to travel over the truncated domes. This exception addresses that situation. It also exempts circulation paths beyond the crossing from the raised path requirement if the circulation path only leads to parking, EVCS, and passenger drop-off and loading zones. This is a nice addition to the code for wheelchair users, while also providing raised paths and detectable warnings where needed for the visually impaired. On a related note, parallel curb ramps with long landings will now be required to have a 36” minimum portion without detectable warnings to allow a wheelchair user to travel in the direction of the sidewalk without passing over the truncated domes (see amended Section 11B-705.1.2.2.2). Section 11B-250.1, Exception 4 In alterations to existing parking facilities, including alterations required by Section 11B-202.4, physical separation may be provided with detectable warnings complying with Sections 11B-247 and 11B-705.1 in lieu of raised circulation paths. In existing parking facilities, raising the elevation of the circulation path can be very difficult. Maintaining positive drainage often requires a much larger area to be altered. This exception allows detectable warnings in lieu of raised paths in alterations to existing parking facilities, including Path of Travel alterations. Section 11B-250.1, Exception 5 Access aisles serving any electric vehicle charging station vehicle spaces complying with Section 11B-812, parking spaces complying with Section 11B-502, or passenger drop-off and loading zones complying with Section 11B-503 shall not be required to comply with this section. This exception is fairly straight-forward. Access aisles are of course exempt from the raised path requirement. Also, detectable warnings shall never be located within access aisles. While I would say the current code already makes this clear, it is now being added more explicitly in the following amended sections: 11B-502.4, 11B-503.4, and 11B-812.3. Section 11B-250.1, Exception 6 At each electric vehicle charging station complying with Section 11B-812 where the charger and its controls are oriented toward the vehicle space it serves and the charger’s clear floor spaces for operable parts and point-of-sale devices are at the same elevation as the vehicle space, the accessible route complying with Section 11B-812.5.2 shall not be required to comply with this section. The intent of this exception is to permit configurations which allow a wheelchair user to access the EV charger and connect it to the vehicle without navigating changes in elevation. It isn’t completely clear what is meant by “…the charger and its controls are oriented toward the vehicle space it serves.” After working on many EV projects, I have found that locating the EV charger at the front of the access aisle and designing the accessible route to connect to the back of the access aisle seems to be the most efficient configuration for dual-port charger applications. The path continues The new code provisions will result in increased accessibility for the visually impaired and provide clarification on the proper application of detectable warnings - which are often over-used or misapplied creating difficulties for many wheelchair users. While the new code language solves some important problems, it also brings with it a few new issues that will require interpretation. As a member of the CALBO Access Committee I can report that our group has been studying these provisions in detail with the goal of assisting our industry in applying them consistently. I hope this article has shed some light on the intent of these new provisions and proves helpful in applying them. Stay tuned for additional information and resources in the coming months. |
