Your speed bump cannot be installed without authorization from the Director of Public Works and/or the County of San Diego Board of Supervisors, and the speed bump design needs to be approved, with input from your local fire district.
Can you tell us where, in that 20 page document that you locate the information about speed bumps. I cannot find anything relevant in skimming the pages, and I don't have time to read all of them thoroughly.
