Lafayette is the heart of Cajun Country and sits in Louisiana's hurricane transition zone — close enough to the coast to feel major storms, far enough inland to avoid the worst storm surge. The back-to-back 2020 hurricane season (Laura and Delta within 6 weeks) demonstrated that Lafayette's exposure is real. SLEMCO and Cleco serve the area, and both cooperatives have invested in grid hardening since 2020.
