A substitute ordinance relating to the permitted use of rain barrels.
Sections
225-4-2.5 cr
Analysis
This substitute ordinance defines a rain barrel as an above-ground prefabricated storage receptacle with an automatic overflow diversion system that collects and stores storm water runoff from the roof of a structure that would have been otherwise routed into a storm drain. A rain barrel must be securely covered, include an inlet screen, have an overflow discharge device and have a convenient and functional means of water withdrawal. The use of a rain barrel is permitted provided the overflow discharge conforms to the requirements of roof rainwater discharge to finished grade or is designed to overflow to a treatment drain or storm water conveyance system. The requirements of roof rainwater discharge to finished grade are as follows:
1. Point of discharge shall be a minimum of 2 feet from a basement or foundation wall of alley property line and 5 feet from all other property lines.
2. Discharge shall flow parallel to or away from the nearest property line.
3. The discharge water shall not discharge to a street, alley or other public way.
4. The discharge water shall not create an icy condition on any pedestrian walkways within or adjacent to the subject premises lot lines.
