Inlet capacities of catch basins will be specifically analyzed according to the anticipated flow calculated by the method detailed in § 55.35 of this chapter. The maximum height of water allowed to pond over inlet structures set in parking, driving, or walking areas will be 0.5 feet from top of grate. The maximum height of water for inlet structures set in road ditches or grassed areas will be 1.5 feet from top of grate. This condition may be waived if, in the opinion of the Director of Public Services, the resulting elevation of water will not cause adverse effects and still fulfills the intent and purpose of this chapter. Under no condition can the water level be more than two feet from the top of casting.
