The City of Miami Gardens' floodplain management ordinance includes a rule that is known as the 50% rule. This rule states that if your structure is damaged or improved to an amount greater than 50% of the structure's market value, it will then have to comply with the current elevation requirements, and other floodplain requirements for that area.
This is important for City residents and business owners to know because many structures built before these rules were created are below the required elevations. If the 50% rule were applied to these structures they would have to be elevated to comply with current rules. Therefore it is important that we all know this rule, know the elevation of our structures, and how that elevation compares with the current standard. This is one reason an Elevation Certificate is so important for all property owners to have.
