Sidewalk Programs and Case Studies
Precision Concrete Cutting (PCC) has run sidewalk trip hazard programs for cities since 2002. The largest have been running for more than a decade: Seattle since 2013, San Francisco since 2016, Colorado Springs for more than 12 years. Each page below gives the client, the years, the hazard count, the miles and how the program is run, using the city's own figures. Across the PCC system, more than 30 million trip hazards have been removed, and about 145,000 tons of concrete have been kept out of landfill across the Seattle, San Francisco and Colorado Springs programs alone.
Long-running municipal programs
Seattle, Washington
Seattle Department of Transportation, 2013 to present. 121,800+ trip hazards repaired across 119 miles of sidewalk, about 6% of the city's 2,100+ miles, in 21 completed survey grids with 3,832+ city work orders. Contract runs through May 2027. An Interlocal Agreement lets neighboring jurisdictions use the contract.
San Francisco, California
San Francisco Public Works, Bureau of Urban Forestry, StreetTreeSF program, 2016 to present. PCC's largest single-city program: 130,000+ hazards repaired across 200+ miles, 25,000 to 30,000 repairs a year, root-heaved panels cut from the top with the street tree preserved. Five-year contract runs through June 2028.
Colorado Springs, Colorado
Colorado's longest-running sidewalk program of this kind: 12+ years with no contract break, 48,000+ hazards repaired, 33+ miles per survey cycle on a 2,426 mile network, with GIS data integrated with the city's asset management system and its ADA Title II Transition Plan since the program began. Serves city public works, HOAs, schools and commercial corridors.
City programs with published results
Tacoma, Washington
4,747 trip hazards surveyed and 2,373 repaired across 33 miles of sidewalk, with part of the surveyed area still to be repaired (project summary presented to the City of Tacoma, September 2025). PCC estimated that replacing the same 2,373 hazards would have meant about 95,110 square feet of sidewalk panel.
Herriman, Utah
5,241 trip hazards repaired over fiscal years 2013 to 2023. PCC estimates that replacing those panels would have meant about 167,712 square feet of sidewalk, and that the program has covered about 15% of the city's sidewalks.
Bountiful, Utah
26,767 trip hazards repaired and 93,591 lineal feet of trip hazard cut over fiscal years 2010 to 2018, run as a yearly program with a different part of the city completed each fiscal year.
How every program is run
The method is the same in every city: survey, cut, verify.
Every hazard is measured, photographed and GPS-located before work begins, in BidBoss, PCC's own field software.
Each hazard is cut to a 1:12 slope, the same slope standard the ADA sets for ramps, in 15 to 20 minutes, with no demolition, no cure time and no full sidewalk closure.
A PCC manager inspects and photographs every cut. Terminal, PCC's program dashboard, will not release a hazard for invoicing until the inspection is checked off.
Data is delivered as ArcGIS-compatible shapefiles, Excel exports and KML files, and survey data is treated as current for one year.
