Accessible vehicle gate and roller guide

Looking for your opinion, if you would accept my proposed accessible path of exit travel below.

The setup

I have an apartment project where the corridor has one (out of 2 total) of its emergency exit doors that leads to a parking lot. The lot is not big enough to qualify as its own "safe dispersal area" so in my opinion, the path-of travel needs to continue to the public right-of-way. Due to the shape of the property and to local planning requirements, there is a pinch-point at which both cars and pedestrians would need to funnel through the same spot at a vehicle access gate in order to reach a public right of way. (In practicality, there will be almost no cars in the parking due to the nature of the residents - - almost none of them qualify to have a driver's license.)

Here's my plan:

* The vehicle gate would have battery backup and be connected to the fire alarm system.

* When the building fire alarm goes off, the vehicle gate rolls (slides on a roller) to the open position.

* The building occupant (let's say in a wheelchair) (1) exits the building, (2) crosses a detectable warning strip and enters the driveway, (3) crosses where the vehicle gate used to be (but it's now wide open), and (4) joins another sidewalk in the front yard, and (5) goes to the public street.

Does this work for you? (Keep in mind I still have one other building exit directly to the public right of way.)

Follow-up question: in #3 above, most rolling vehicle gates have a bottom metal guiderail track that is about 1" tall - - taller than an ADA threshold. Has anyone seen an acceptable alternative? I'm thinking about something that would be the functional equivalent of a drainage grate that a wheelchair can cross over.
 
You really think it safe to direct both cars and pedestrians through the same spot at a vehicle access gate in order to reach a public right of way? Do you think a driver is going to wait for a wheeler to get out of the way when you have a burning building?

bad initial concept Do you think a driver is going to wait for a wheeler to get out of the way when you have a burning building?

Yikes, Is this in CA?

Have you considered a recessed track? Or a semi recessed track ?
 
mark - good questions.

Yes, it is in California.

I freely admit it's not the ideal condition. I wouldn't normally do this, but:

(a) in reality there will be virtually no cars. Most residents are on psychotropic meds that enable them to live independently, but leave them unable to drive. The only cars will be dial-a-ride, or emergency vehicles.

(b) in most communities, a single 12' wide gate would be sufficient to service 14 parking stalls, leaving room for an adjacent pedestrian gate. In this community, the planning dept. requires a 20' wide vehicle gate, hogging all the available space.

© the site shrunk due to a highway dedication, but the funding requirements / # of units remained the same. That's what forced my hand.

(d) there was another route that didn't go through the parking lot - - it was down a side yard, but that's been chewed up by a stormwater retention basin / swale.

(e) the occupant load is so low, I could almost make the building work with just one exit directly to the street, ignoring this second exit... except that it's also a 2-story structure.

I'm literally backed into a corner here.
 
Just a few thoughts fron the CBC

undiminished and unobstructed path of travel from any occupiable point in the building to the public way.

provide a visible delineation along the path of travel.

Where a gate is used, the bottom of the gate shall be within 3 inches of the surface of the path of travel. The surface of the gate on each side shall be smooth to present no hazard to 'persons with disabilities using the gate and shall be structurally adequate to allow it to be opened with the wheelchair foot pedals.
 
Thanks, mark.

I have a situation where a gate is normally closed, not used by pedestrians due to security issues,

but then opens itself (with battery backup) and stays open when the fire alarm goes off,

so would it need to be openable with wheelchair foot petals, or could an exception be made as an alternate means of compliance?

As an analogy - - over at Dodger Stadium they have some giant pedestrian gates that are normally closed. At the end of the game,the employees swing them to the open position, and people can freely walk in or out. The typical occupant never touches the gate, so it doesn't matter that the gates are wider than 4', don't have accessible features, etc.

My gate actuation is similar, except I substitute "motor" for "employees"; "fire alarm" for "end of game"; and "slide" for "swing".
 
It may not normaly used by pedestrians, but if it is you emergency POT, in CA, it must comply with pedestrian, POT requirements
