  "articleBody": "Accessible parking and site paving in Los Angeles County must comply with the **Americans with Disabilities Act (ADA)**, the **2010 ADA Standards for Accessible Design**, and the **California Building Code (CBC)**, which contains additional state‑level requirements. The U.S. Department of Justice’s ADA standards prescribe minimum numbers of accessible spaces, dimensional requirements, slopes, and signage. The CBC, enforced by local building departments in Los Angeles County cities and unincorporated areas, often requires more accessible spaces and specific configurations beyond federal minimums. For paving contractors and owners, this directly affects **grading, striping, and layout**. ADA and CBC require that accessible parking spaces and access aisles have slopes not exceeding 2 percent in any direction. This means the asphalt or concrete surface must be carefully paved and compacted to maintain tight slope tolerances, often verified with digital levels or survey instruments during construction. The standards specify minimum stall widths, length, and the arrangement of van‑accessible spaces with access aisles. Striping and signage are equally regulated. ADA guidance and CBC chapters on accessibility require **high‑contrast striping** and specific symbols, including the International Symbol of Accessibility, as well as “Van Accessible” designations where applicable. California’s accessibility standards also detail curb ramp placements, detectable warnings at transitions to pedestrian paths, and clear routes from accessible parking to building entrances. Los Angeles County and City plan checkers typically review site plans for compliance before issuing permits. Failure to meet these paving and striping requirements can lead to correction notices, permit delays, or accessibility complaints, so many facility managers expect paving contractors to be familiar with ADA/CBC diagrams, standard details, and current Department of Justice and California Division of the State Architect guidance.",
