Install code-compliant foundation flood vents, Avondale Ave, Franklinton

An enclosed crawlspace below the Franklinton floodwall's protected grade still needs to equalize hydrostatic pressure in an extreme event per FEMA floodplain practice; engineered flood vents are the code-compliant way to do that without relying on the walls to fail first. Standard: FEMA floodplain + green-infrastructure siting screen; SDG 11.5 disaster resilience. Proof: Before photo of the foundation wall + net-open-area calculation + Cutting/installation photos of each vent + Finished photo set confirming vent count/placement meets the calculated requirement Method (FEMA floodplain + green-infrastructure siting screen; SDG 11.5 disaster resilience.): 1. Confirm the required net open vent area against the enclosure's square footage per the FEMA/ICC formula and photograph the existing foundation wall. 2. Mark and cut the vent openings to the engineered vent's rough-opening spec, keeping openings on at least two exterior walls. 3. Set and fasten each engineered flood vent per its listing/instructions, sealing the perimeter weathertight. 4. Photograph the finished vents, confirm the total net open area meets the calculated requirement, and log the vent model/count for the permit record. Done when: Before photo of the foundation wall + net-open-area calculation + Cutting/installation photos of each vent + Finished photo set confirming vent count/placement meets the calculated requirement

How this work is done

A documented method, so this packet comes out the same whoever does it. Typically 45–90 minutes. Method of record: FEMA floodplain + green-infrastructure siting screen

Bring

• GPS phone
• tape/ruler for deposition depth
• metals field kit (if sediment screen in scope)
• boots + gloves
• camera

Steps

1. 1. Confirm post-event conditions are safe; navigate to the site; record GPS.
2. 2. Photograph deposited sediment / affected area.
3. 3. Measure deposition depth at representative points.
4. 4. If a sediment contaminant screen is in scope, run the metals field kit and record values.
5. 5. Note debris, hazards, and the extent (sketch).
6. 6. Enter depth, any analytes, hazard notes, GPS, photos into the proof record; sign.

If it does not match the plan

• Unstable ground / submerged debris / contaminated water -> document from safe footing; do not enter.
• Elevated metals in deposited sediment -> flag before any reuse; recommend lab confirm.

What counts as done

• Deposition depth recorded at representative points
• Metals screen recorded (if in scope)
• Debris/hazard note + extent sketch
• GPS waypoint + timestamped photos

Proof is measured against these, not judged by taste.
