Repair a heaved sidewalk panel with a permeable finish, St. Ann's Avenue block

Root-heaved, cracked sidewalk panels on St. Ann's Avenue block trip people daily and shed every drop of rain to the gutter. Repairing to ADA grade with a permeable finish fixes the fall hazard and turns the surface into infiltration. Standard: ADA + PROWAG (36 CFR 1190) — accessible public rights-of-way (R302); EPA permeable pavement BMP. Proof: permit + before/after photos + level readings + infiltration water-test video + GPS Method (ADA + PROWAG (36 CFR 1190) — accessible public rights-of-way (R302); EPA permeable pavement BMP.): 1. Measure and photograph the failed panel (lift height, cross-slope, ponding); confirm the right-of-way permit and 811 utility locates before cutting. 2. Set cones/barricades and a pedestrian detour; all work stays out of the traffic lane. 3. Remove the failed section using wet-cut dust controls; correct the subgrade or root cause (root-prune only per the city arborist standard). 4. Place open-graded base and the permeable surface to ADA/PROWAG slope and lippage limits, then verify with level photos and a water-test. Done when: permit + before/after photos + level readings + infiltration water-test video + GPS

How this work is done

A documented method, so this packet comes out the same whoever does it. Typically 240–600 minutes. Method of record: Sidewalk panel repair with permeable finish per ADA/PROWAG surface requirements + EPA permeable pavement BMP, under municipal right-of-way permit — trained crew with wet-cut dust controls; assess→repair→verify

Bring

• right-of-way permit + traffic cones/barricades and signage
• wet-cut saw or grinder with water feed + vacuum (dust control), or paver lift/reset tools
• permeable paving material (permeable pavers/pervious mix) + bedding aggregate + compactor
• 2-ft level / smart level + measuring wheel + camera

Steps

1. 1. ASSESS: measure and photograph each displaced/cracked panel (lift height, cross-slope, ponding), mark the repair extent, and confirm the right-of-way permit and utility locates (811) before any cutting.
2. 2. Set up cones/barricades and a safe pedestrian detour; keep all work out of the traffic lane.
3. 3. Remove or wet-cut the failed section with water-fed dust controls; excavate to the design subbase and correct the root or subgrade cause (root-prune only per the city arborist standard).
4. 4. Place open-graded base and the permeable surface (pavers or pervious mix) to ADA/PROWAG slope and lippage limits; compact and edge.
5. 5. VERIFY: check cross-slope ≤2% and vertical discontinuity ≤1/4 inch, water-test infiltration, photograph before/after from the same vantage, and close out the permit.

If it does not match the plan

• No utility locate (811) or no right-of-way permit -> STOP: do not cut.
• Any cutting/grinding without water-fed dust control -> STOP (respirable silica); wet methods or vacuum shroud are mandatory.
• Structural failure larger than a panel (undermining, sinkhole) -> document and route to the city engineer; do not patch over.

What counts as done

• Finished surface meets ADA/PROWAG: cross-slope ≤2%, lippage ≤1/4 inch (level photos)
• Water-test photo/video shows infiltration through the permeable section (no ponding)
• Before/after photos from matching vantage + permit close-out reference
• Pedestrian detour maintained for the whole work window (setup photo)

Proof is measured against these, not judged by taste.
