Engineering Solutions For Flood Risk Management

ASCE 24 and RiskFootprint(tm) 500-year Flood Maps! ASCE 24 standard, developed by the American Society of Civil Engineers, is a critical guideline for designing and constructing buildings in flood-prone areas. It establishes minimum requirements to ensure structures are resilient against flooding. Its importance lies in reducing flood-related damages, protecting lives, and enhancing community resilience. The recent update to ASCE 24-24 introduces significant changes, including a shift to the 500-year flood event as the design standard for most structures. This means that buildings are now designed to withstand floods with a 0.2% annual chance of occurrence, rather than the previous FEMA 100-year flood standard (1% annual chance). This change reflects the increasing frequency and severity of flooding events (including extreme rainfall) due to climate change and aims to better protect communities. The new RiskFootprint(tm) Version 17 includes the Fathom (Swiss Re) 500-year flood maps for pluvial, fluvial, and coastal flooding. Key updates in ASCE 24-24 include: Expanded Flood Hazard Areas: Now includes the 500-year floodplain, offering broader protection. Elevation Requirements: Structures must be elevated based on their flood design class, with critical facilities requiring even higher standards. Climate Change Considerations: Incorporates sea level rise and other future climate impacts into floodplain calculations. Enhanced Dry Floodproofing: Updates to materials, inspection, and maintenance requirements for floodproofing measures. These updates represent a proactive approach to flood prevention, aiming to reduce economic losses and safeguard communities against increasingly severe flooding events. Our RiskFootprint(tm) Resilience Sherpas will help you make your new or existing buildings safer and more resilient. Find out more at RiskFootprint dot com.

When Hurricane Helene brought heavy flooding to the Tampa Bay area, many feared the worst for coastal facilities. Yet, Tampa General Hospital, the region's only Level 1 trauma center, equipped to handle the most critical emergencies, stood resilient, remaining dry and fully operational despite the surging waters. 𝐇𝐨𝐰 𝐃𝐢𝐝 𝐓𝐡𝐞𝐲 𝐃𝐨 𝐈𝐭? The hospital employed a temporary flood barrier system using Aqua Fences that acted like a robust fence, effectively keeping the floodwaters at bay as the hurricane passed through. Developed by a Norwegian company, AquaFence is an industrial-grade, waterproof barrier designed for rapid deployment in flood situations. Here's what makes it remarkable: - 𝐍𝐨 𝐍𝐞𝐞𝐝 𝐟𝐨𝐫 𝐒𝐚𝐧𝐝𝐛𝐚𝐠𝐬: Unlike traditional flood defenses, the AquaFence doesn't require sand or other fill materials to reinforce it. - 𝐌𝐨𝐝𝐮𝐥𝐚𝐫 𝐃𝐞𝐬𝐢𝐠𝐧: It's made up of interlocking panels that can be quickly assembled to shield entire buildings or specific entry points. - 𝐒𝐭𝐚𝐛𝐢𝐥𝐢𝐭𝐲 𝐢𝐧 𝐇𝐢𝐠𝐡 𝐖𝐢𝐧𝐝𝐬: Anchored with straps to the ground, it stays firmly in place even when strong winds blow. - 𝐒𝐞𝐥𝐟 𝐒𝐭𝐫𝐞𝐧𝐠𝐭𝐡𝐞𝐧𝐢𝐧𝐠: As floodwaters rise, the pressure actually enhances the wall's stability, making it more effective the higher the water gets. Protecting this facility during a hurricane isn't just about safeguarding property; it's about ensuring uninterrupted care for those who need it most when disaster strikes. Recognizing this critical responsibility, the hospital demonstrated foresight and a commitment to community safety by acquiring this flood solution in 2019. During Hurricane Helene, this preparation paid off, allowing medical staff to continue their vital work without interruption.
