El Centro highlights concrete-slicing program that has repaired hundreds of sidewalk trip hazards

El Centro city staff and a vendor told the City Council on Jan. 21 that a concrete-slicing approach has been used across the city to remove dozens of sidewalk trip hazards since 2022 and that the city is preparing to expand the program.

The update, presented by Abraham Campos of the Department of Public Works and by representatives of Precision Concrete Cutting, said the city has identified and addressed 366 locations since about 2022 using the vendor’s vertical “slice” method. The presenters said the work targeted vertical rises mostly between about a half-inch and 2 inches and that the slicing approach can bring sidewalks into Americans with Disabilities Act (ADA) alignment at a fraction of the cost of full panel removal and replacement. The presentation was informational; council took no vote on the item.

Precision Concrete Cutting’s representative described the method to the council: “We specialize in the slicing of trip hazard repairs,” and said the process slices vertically rather than grinding or removing and replacing full panels. The vendor said the repairs can be completed quickly without sidewalk closures and that, compared with traditional remove-and-replace, the slicing approach has allowed an estimated cost savings the presenters described during the meeting as roughly $440,000 over the last three years.

Why it matters: Sidewalk trip hazards are a liability and accessibility issue for pedestrians, seniors and people using mobility devices. The city said the pilot’s lower cost and fast work days make it feasible to address more locations sooner, and staff emphasized the project supports ongoing ADA-compliance and asset-management efforts.

Details from the presentation

- Scope and results: Presenters said 366 locations have been addressed since 2022 and described roughly 356 repairs completed “on and off over the 3 years on only 15 working days.” The repairs focused on vertical differentials between about 0.5 and 2.0 inches.

- Method and performance: The vendor said the system is a dry vacuum, waterless cutting system with dust abatement and that the slice is intended to remove raised portions and recycle debris. A vendor representative noted a roughly 13% chance of regrowth (re-lifting) over time in some locations and said the method’s lower price makes returning to re-slice more economical than a complete remove-and-replace.

- Cost and recordkeeping: Presenters said the slice method produces major savings compared with remove-and-replace and that the Department of Public Works has worked with GIS staff to map repairs. Council staff showed a map with green markers for completed repairs and yellow markers for planned projects; staff said the yellow markers on the map represent new CDBG-funded ramps and new construction projects rather than slice repairs.

- Program design and next steps: Campos said the project has been run reactively — staff identifying high-priority spots — but recommended a proactive sidewalk-condition assessment and a quadrant-based rotation tied to an annual budget. He said the city could use the CJPIA (insurance pool) master-service agreement to “piggyback” the vendor’s contract and expand scope under an existing procurement vehicle. Campos said staff will return with master agreement and budget recommendations for council consideration.

- Resident reporting and responsibility: Staff reminded the council that the city’s citizen-support portal (the “Fix It”/citizen support tool) allows residents to report sidewalk problems. Campos also stated, citing California law, that maintenance responsibility for most sidewalks rests with adjacent property owners and that the city program will not solve every location but helps reduce hazards and liability in high-use areas.

Council and public reaction

Council members asked technical questions about dust control, long-term durability and where the program would focus next. One member asked whether the cutters use water for dust abatement; the vendor replied, “It’s a completely waterless system, dry vac system,” and described the dual dry-vac arrangement. Council members also pressed staff on how many repairs remain; Campos said the remaining scope is “undetermined” until staff performs the systematic assessment and returns with a budget and rotation plan.

Ending

Staff said they will continue to refine the GIS tool (including before-and-after photos), pursue use of the CJPIA master agreement and return to council with a proposed master agreement and budget to scale the program. The item was presented for information; no formal action was taken.
