Subject to the availability of adequate mapping and data to properly identify the floodplains, if any, within its jurisdiction, each local government is encouraged to adopt a floodplain map and floodplain management ordinance which identifies these floodplains and which requires, at a minimum, that any development in a floodplain must be constructed at a flood protection elevation and/or have adequate floodproofing. The local government may regulate all mapped and unmapped floodplains within its jurisdiction. Nothing in this act shall prohibit a local government from adopting more restrictive standards than those contained in this chapter. If not otherwise exempt from approval, a flood control district’s conduct of a "flood fight," as defined in section 42-3103 , Idaho Code, shall not require prior local government approval provided all such approvals are obtained within a reasonable time after the imminent flooding event has ended.
