Notwithstanding anything else in this chapter to the contrary, whenever the subdivider anticipates more than one final plat arising from an approved preliminary plan, the subdivider shall submit, along with the construction plans for any final plat, the drainage and detention plans for each watershed that is affected by the construction of the final plat. If a watershed is partially affected by any final plat, then the subdivider shall submit drainage and detention plans for the entire watershed irrespective of whether the watershed is located partially outside the plat. No final plat shall be approved until all construction work is completed, or security is given for construction of drainage and detention works for all watersheds affected by the final plat. Until all drainage works for the entire subdivision are built, provisions shall be made in the construction plans if necessary for temporary detention works for each plat as each plat is built.
