Which codes and exemptions should I review?

The reviewed sources do not identify a general current 2026 county building-code edition for ordinary construction. The floodplain ordinance excludes maintenance of existing buildings and facilities such as re-roofing, road resurfacing, gardening, plowing, and similar agricultural practices that do not involve filling, grading, or construction of levees. Other development in the regulated flood hazard area requires a permit before work begins.
