19.1.7 Maintenance and Operation

Project completion and ADA compliance of pedestrian facilities does not end at construction project closeout. Continuous maintenance is required to enable the pedestrian facilities to remain functional for every pedestrian. Maintenance of the PAR includes, but is not limited to:
  • Cleaning silt and debris that accumulate in ramps and on sidewalks;
  • Removing vegetation overgrowth in the pedestrian zone;
  • Repairing or replacing noncompliant surfaces due to settling, frost heaving, or root heave issues;
  • Replacing fading crosswalks and pavement markings;
  • Replacing worn detectable warning surfaces;
  • Replacing missing or faded pedestrian signage;
  • Maintaining 80” vertical clearance, 84” for signs, in pedestrian circulation path; and
  • Adjusting pedestrian crossing signal timing with changes in traffic demands.
Pedestrian facilities should be incorporated into maintenance plans or agreements to maintain ADA compliance and general pedestrian safety and comfort.
