Amid increasing frequency of extreme weather events like heavy rainfall and flooding, building owners and property managers must adopt proactive measures for storm preparedness to safeguard structures and residents. Storm resilience for buildings has become essential following the historic rainfall in New York City in September 2021—which caused widespread flooding, power outages, and infrastructure damage—the Department of Buildings (DOB) issued guidelines for assessing and addressing storm-related risks. This article outlines immediate response steps, long-term resilience strategies, health hazards to monitor, and challenges in implementing safety protocols, alongside expert recommendations.
Immediate Steps After Storms
Assessing Structural Safety
Before entering a building, inspect for visible hazards such as cracked walls, sagging beams, or gas leaks. Follow these actions for storm resilience for buildings:
| Action | Details |
|---|---|
| Exterior inspection | Check for wall cracks or leaning supports |
| Electrical systems | Turn off power if wiring is wet or corroded |
| Water removal | Use pumps to drain standing water and prevent foundation damage |
Source: The Federal Emergency Management Agency (FEMA) advises, “Do not enter buildings until a qualified engineer confirms structural integrity,” as outlined in its Homeowner’s Guide to Disaster Recovery.
Addressing Interior Damage
Floodwaters increase the risk of toxic mold growth, especially in porous materials like drywall and carpeting. Remove damaged materials within 48 hours to ensure storm resilience for buildings and replace them with moisture-resistant alternatives.
Proactive Strategies to Enhance Building Resilience
Upgrading Drainage Systems
Install larger-diameter rainwater pipes and backflow valves to prevent sewer backups. Ensuring storm resilience for buildings requires these upgrades, as noted by the U.S. Environmental Protection Agency (EPA), “Improved drainage systems can reduce internal flooding risks by up to 60%.”
Using Weather-Resistant Materials
Replace standard windows with waterproof models and apply polymer sealants to exterior walls.
| Material | Features |
|---|---|
| Tempered glass | Withstands wind pressure and impacts |
| Polymer coatings | Prevent water infiltration through cracks |
Health Risks Associated with Flooding
Mold Growth
Moisture trapped in walls and ceilings fosters mold, which can trigger respiratory issues. Clean affected areas with a diluted bleach solution (1 cup bleach per 4 gallons of water), as recommended by the New York City Department of Health.
Water Contamination
If plumbing systems are compromised, boil water until tests confirm it is free of bacteria. The city’s health department offers free on-site water quality testing kits.
Implementation Challenges and Proposed Solutions
Despite available guidelines for storm resilience for buildings, building owners face obstacles such as high retrofitting costs and limited awareness.
- Challenge: Budget constraints for upgrading drainage systems.
- Solution: Utilise state-funded programs like New York’s “Climate Infrastructure Rebuilding Grant,” which covers up to 50% of eligible costs.
- Challenge: Delays in inspections due to a shortage of certified technicians.
- Solution: Partner with DOB-certified maintenance companies to expedite assessments.
ArchUp Opinion: Analysis and Discussion
While current measures aim at ensuring storm resilience for buildings are critical, gaps remain in enforcement and public engagement. Many older buildings still rely on outdated drainage systems, increasing flood vulnerability. We propose legislative reforms requiring mandatory infrastructure updates every ten years, coupled with financial incentives to encourage compliance. Additionally, community education is essential—residents often overlook health risks like mould. Local governments should organise free workshops in high-risk neighbourhoods to teach hazard mitigation techniques.
Frequently Asked Questions (FAQ)
Is entry into the building allowed after a flood?
No, until a licensed structural engineer verifies there are no foundation cracks or collapse risks.
How should I handle flood debris?
Wear protective gear (gloves, goggles), remove solid waste first, then disinfect surfaces with approved sanitizers.
Do standard insurance policies cover flood damage?
Most do not. Consider purchasing a separate policy through the National Flood Insurance Program (NFIP).
Summary Table
