Request #19-4529

I’m with Detectable Warning Systems and we are 25 year manufacturers of ADA and CalTrans approved detectable warnings.  I was trying to find out if the City of Oakland had a specific APL/QPL list of approved or required detectable warnings that can be installed within the city. If so could you please let me know who I need to contact or what the process is to be added to the list?  Thank you in advance for your assistance.
