The valuation of the project is cumulative. Therefore, if during construction changes are made to the permit; those valuations must be added to the total valuation submitted for the project. If during construction the project increases to over 50% of the depreciated market value of the structure, it must conform to the City's current floodplain management regulations. Project valuations are cumulative for two years, meaning that all open permits for a structure are totaled together. A permit must be finaled for two years before a new project can begin to avoid it having a cumulative effect on valuation.
