Repair the curb ramp at the 7th Street corridor intersection

The corner ramp at the 7th Street corridor intersection near Mandela Grocery Cooperative predates current ADA/PROWAG geometry. Standard: Curb ramp repair/retrofit — ADA + PROWAG R304 (slope, landing, detectable warning), municipal right-of-way permit. SDG 11. Proof: Before measurements against R304 limits + Permit + 811 locate references + After measurements on the level + Detectable-warning panel photos + gutter water test Method (Curb ramp repair/retrofit to ADA + PROWAG R304 (slope, landing, detectable warning surface), under municipal right-of-way permit — trained crew with wet-cut dust controls; assess→repair→verify, ~240-600 min): 1. ASSESS: measure the existing ramp against PROWAG R304 (running slope ≤8.3%, cross-slope ≤2%, landing, flush transition, detectable warning) and photograph each failure; confirm permit + utility locates before cutting. 2. Set up cones/barricades and a safe pedestrian detour outside the work zone. 3. Remove the failed ramp section with wet-cut dust controls; form and place the corrected ramp geometry per the city standard drawing. 4. Set the detectable warning surface (truncated domes) aligned and embedded per spec; finish transitions flush with the gutter. 5. VERIFY: re-measure every R304 dimension with the smart level, photograph readings + before/after from matching vantage, water-test the gutter flow line, and close out the permit. Equipment: right-of-way permit + cones/barricades + pedestrian detour signage, smart level / digital inclinometer + tape measure, concrete tools + detectable warning surface (truncated dome) panel per city standard, wet-cut saw with water feed (dust control) Done when: Measured running slope ≤8.3% and cross-slope ≤2% with level photos; Detectable warning surface installed per standard (alignment + embed photos); Flush gutter transition verified (no lip >1/4 inch; water flows along the gutter line); Before/after photos + permit close-out reference

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash. You see which before you claim, never after.

Proof

Before measurements against R304 limits + Permit + 811 locate references + After measurements on the level + Detectable-warning panel photos + gutter water test

This is exactly what gets it approved. Nothing settles without it.

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: Curb ramp repair/retrofit to ADA + PROWAG R304 (slope, landing, detectable warning surface), under municipal right-of-way permit — trained crew with wet-cut dust controls; assess→repair→verify

Bring

• right-of-way permit + cones/barricades + pedestrian detour signage
• smart level / digital inclinometer + tape measure
• concrete tools + detectable warning surface (truncated dome) panel per city standard
• wet-cut saw with water feed (dust control)

Steps

1. 1. ASSESS: measure the existing ramp against PROWAG R304 (running slope ≤8.3%, cross-slope ≤2%, landing, flush transition, detectable warning) and photograph each failure; confirm permit + utility locates before cutting.
2. 2. Set up cones/barricades and a safe pedestrian detour outside the work zone.
3. 3. Remove the failed ramp section with wet-cut dust controls; form and place the corrected ramp geometry per the city standard drawing.
4. 4. Set the detectable warning surface (truncated domes) aligned and embedded per spec; finish transitions flush with the gutter.
5. 5. VERIFY: re-measure every R304 dimension with the smart level, photograph readings + before/after from matching vantage, water-test the gutter flow line, and close out the permit.

If it does not match the plan

• No permit or no utility locate -> STOP: do not cut.
• Cutting without water-fed dust control -> STOP (respirable silica).
• Geometry cannot meet R304 within the existing footprint -> document and route to the city's ADA transition-plan engineer instead of pouring a non-compliant ramp.

What counts as done

• Measured running slope ≤8.3% and cross-slope ≤2% with level photos
• Detectable warning surface installed per standard (alignment + embed photos)
• Flush gutter transition verified (no lip >1/4 inch; water flows along the gutter line)
• Before/after photos + permit close-out reference

Proof is measured against these, not judged by taste.
