Accessibility: Signage

During our travels, we see a lot of unique accessible signage.  Here is a big reinforced concrete post which appears to be durable.  Sometimes we find large bases are not buried deeply into the pavement but are just sitting on the surface.  For good resistance to toppling, a bollard should […]

Accessibility: Accessible Sign Height

The American Disabilities Act Accessibility Guidelines (ADAAG) specifies accessible parking stall must have a permanent sign for each parking stall.  Without a sign, the stall is not considered an accessible stall.  In earlier ADAAG versions, the sign height must be visible when a vehicle parked in the stall.  The latest […]

Maintaining An Accessible Route

When a construction barrier or screen is placed on a sidewalk, an accessible route must be maintained.  The sidewalk width must be a minimum of four feet with five-foot passing areas every 200 feet (R302 Pedestrian Access Routes R302.3.1).   Zimmer Consultants photograph

Accessibility: No Ramps at Doors

According to the ADAAG, a manually operated door must have a five-foot flat (slopes at 2.1% or less) landing area.  The photograph shows original construction and a reversed ramp. The slope is in excess of 2.1%. To become compliant, the sidewalk will have to be replaced.  Zimmer Consultants photograph

Accessibility: Unique Signage

A unique signpost using tubular steel was observed at one of our projects. We did some investigation on installation and cost. An Internet steel supplier has 12” by 4” rectangular tubes in 10-foot lengths for $387 before tax and shipping. The Zimmer standard is a 2” by 2” square post inserted into […]

Accessibility: Parking Stalls, Over Doing It

We saw this accessible parking configuration in a Houston parking lot.  It is admirable to extend the accessible access-way behind the parking stall to extend the accessible route, but it is unnecessary.  The increased limits of accessible route mean the area must be leveled to less than a 2% slope […]

Accessibility: Parallel Curb Ramps

Even when detailed plans are provided and there is a project walk through, we find curb ramps are still incorrectly installed. At this installation, the ramp center should be flat (less than 2% slope). A flat area is necessary to allow for a wheelchair turning or maneuvering area. It is […]

Accessibility: A Long & Winding Route From A Bus Stop

We were at a mall with a series of short sidewalks with curb ramps connecting a bus stop with the shopping center building. It is inaccessible because the ramps are noncompliant, and the sidewalks between the ramps have cross-slopes greater than 2.1%. The sidewalk also gives the appearance of forcing […]
