Designing for High Winds in Louisiana

New Orleans Area Habitat for Humanity (NOAHH) graciously hosted the Front Porch team on a visit to advance our latest partnership, a replacement house as part of Hurricane Ida recovery efforts in fishing communities south of New Orleans, LA. Our response to this project addresses an intersection of climate hazards; the house will be designed for both hurricane-force winds and flooding.

Our first day began with a field trip of precedent projects, including a recently completed Habitat home in the Gentilly Terrace neighborhood of New Orleans. The construction team explained the aspects of the home that are new to this affiliate: a vaulted ceiling in the main living space, a second bathroom (new to their three-bedroom plan), dedicated fresh air ventilation, storage for hurricane shutters, and a second porch off the kitchen at the rear of the house. We studied the foundation of treated wood piles supporting the raised wood floor system, as this system will be employed on the proposed project.

Because the house will need to be elevated above the FEMA Base Flood Elevation for flood mitigation, we met with the structural engineer, Steve Cali, to consider strategies for supporting the house 14 feet above grade. Julie Shiyou-Woodward of Smart Home America joined the discussion to clarify structural requirements of the FORTIFIED standard and to share the benefits of certification on insurance premiums. As the last blog post referenced, increasing resilience and durability of the home through minimal up-front investments can reduce a homeowner’s insurance premiums, contributing to the long-term affordability of the home and financial stability for the homeowner. In particular, Louisiana insurance carriers offer discounts for homes certified to the FORTIFIED standard. Fannie Mae’s Disaster Recovery & Rebuilding team also met with NOAHH and the Front Porch team to share potential financing opportunities for this and future projects.

The following day, the group traveled south of New Orleans to visit a few potential project sites located in fishing communities within Plaquemines and Jefferson parishes who working to rebuild in the aftermath of Hurricane Ida. As the source of 30% of Louisiana’s seafood, these communities have been described as a “working coast,” critical to the region’s economic recovery. These site visits illuminated the challenges of recovery, particularly in the face of steep flood insurance premium increases and material shortages due to supply chain issues; but community members expressed eager optimism and a fierce will to rebuild. NOAHH is working closely with the municipalities to coordinate efforts and mobilize construction crews while the Front Porch team finalizes construction documents. NOAHH aims to have the first house completed by August 29, 2022, the anniversary of hurricanes Ida and Katrina.
