Article 11. Storm Drainage (18-29-1101 et seq.)

All roofs exceeding 750 square feet (69.7 m

) in area shall be drained to a sewer, where such is available in any adjoining public way, or public place. Every connecting roof downspout having the open roof connection, located nearer than 12 feet (3.66 m) to an inside lot line or any door or window on the same premises, shall be trapped on the downspout side of the connection to any sanitary sewer or any combined sewer or drain, and shall be set where not subject to frost.
Exceptions:
1. Nothing in this provision shall prohibit the temporary or permanent disconnection of the roof downspout of a building from the sewer or combined sewer so long as the disconnection does not result in the drainage of water beyond the property lines of the lot on which the building is located, or create a public hazard or nuisance.
2. Roofs of buildings of Group R-2, R-3, R-4 or R-5 occupancy and single-story buildings of any occupancy may be provided with external downspouts discharging onto a paved or landscaped area, provided the water thus discharged can be drained directly to an area drain or catch basin connected to a public sewer, without spilling over onto adjacent property, including the public way, or creating a public hazard or nuisance.
3. If there is a conflict between this section and a site's stormwater management plan approved by the department of water management, the stormwater management plan shall prevail.

Outside areas exceeding 400 square feet (37.2 m2), and not more than 5,000 square feet (1,524 m2), where connected to sewers, shall be connected through a catchbasin, not less than 3 feet (915 mm) in diameter and not less than 3 feet (915 mm) deep below the bottom of the trap. Areas of more than 5,000 square feet (1,524 m2) shall be provided with a catchbasin not less than 4 feet (1,220 mm) in diameter and not less than 3 feet 6 inches (1,067 mm) deep below the bottom of the trap. To the extent possible, no sheet flow or discharge of stormwater that creates a public hazard or nuisance shall be allowed to adjacent private property or the public way.
