Properties located in high-risk flood zones (SFHAs) face mandatory flood insurance requirements, which can increase transaction costs and affect property values. The new Risk Rating 2.0 methodology may lead to higher premiums for some property owners, depending on factors like proximity to water and historical claims. Wetlands identified under federal jurisdiction may require Section 404 permits, potentially delaying or preventing development. Real estate professionals and property owners must stay informed about these regulations to avoid unexpected costs and legal complications.
