CODE states Sizes. Stormwater conveyance pipes and cross culverts shall be a minimum of 18 inches diameter or equivalent. Driveway culverts shall be a minimum of 15 inches diameter or equivalent for residential use and a minimum of 18 inches diameter or equivalent for commercial use.

CODE states Drainage facilities. (1) Pipe size and materials. (a) Drainage pipes shall be a minimum of 15 inches for residential and commercial driveways and 18 inches in diameter for all other stormwater systems within a right-of-way or easement associated with the right-of-way.
APPLICANT states roof drains prior to connection to the overall system are exempt from minimum size. Area drains shown (D-5 and D-6) are for landscape areas. These drains collect water within the grass areas and convey it to the stormwater pond.
