How many of you guys in California are enforcing the CBC requirements of staggered domes
most of the Detectable warnings I see in CA are INLINE

maniac, the ones I have seen installed are offset. Do you have a photo of the INLINE ones? Fred

Maniac, Got the photos, what section does it specifically say offset ? I see them offset in the picture in figure 11B-23A. What section in code says they need to be staggered ? Thanks Fred

The following is a link to the a pdf of the DSA's interpretation of regulations regarding curb ramps, specifically IR 11B-4

"....This interpretation clarifies acceptable design and installation requirements of
detectable warnings at curb ramps under Division of the State Architect (DSA) jurisdiction,
which includes state funded buildings and facilities, State of California public elementary and secondary schools (grades K-12), community colleges, and universities.


NOT FOR 95% of work in California....


And if you read it it requires classifies it as a "alternative design".

Maniac:
Doesn't DSA's jurisdiction include privately funded public accommodations?

The wording in the document in the link is "...(DSA) jurisdiction, which includes state-funded buildings and facilities, State of California public elementary and secondary schools (grades K-12), community colleges, and universities..."

Is this intended to mean that the interpretation doesn't cover the other projects under the DSA's jurisdiction?
Thanks,

DSA does NOT have jurisdiction over non-listed projects.

CalDAG requirements show the domes to be offset.
Here UCSB we are using the offset for all new work and replacing the old inline pattern as sidewalks are repaired or replaced.

CalDAG is based on 2001 CBC, no longer valid.
Thanks for your UCSB info...

Interesting read on this thread from the Californians.
Can the rest of the country assume changes in the detectable warning in the next ANSI?
Who and why did they decide a change needed to be made in California?
Was inline not working?

I just wonder where we are headed with accessibility codes. Will someone decide in 2015 that the current domes really aren't good enough and we need to do something else?

We have CalTrans for Main and 12th Streets and CBC ADA regs for the rest of town. Of course, we don't have many sidewalks here either............

My understanding as to why in-line truncated domes are an issue is: wheelchair wheels get caught in the space between.

maniac, I have checked around other cities in my area here in the Northern california and I have not seen one installed that was offset, not one! So, the ones they are installing must be approved for truncated domes and accepted. I have checked new and existing installations, and they are all inline. Any Cities installing staggered domes out there ? How is everyone else out there inspecting for these ? Fred

Just because they are "...installing(them, they)must be approved..."

Not by CBC.

Thanks for the comment.

Both DSA and Caltrans will accept an inline pattern.

However local building departments make the call on whether they will accept an inline pattern for their own jurisdictions.

I know of not one building department that has refused to accept an inline pattern, but they certainly could.

Enforcer. I was just down in Los Angeles and they are in line. I have not seen a single one that is staggered in California, not one! Thanks for the comment, Fred
