(A) Roof and downspouts, footing, or foundation drains shall be discharged onto the same parcel of land from which the water is generated. Roof downspouts shall be piped to natural draining areas away from the street or onto concrete splash blocks, which direct water away from the building structure into swales or other natural drainage areas. Downspouts and sump pump pipe outlets that discharge water in the direction of the public street right-of-way shall extend toward the public street right-of-way at least five feet (5')and no more than ten feet (10') from the building foundation wall. No additional roof or subsurface drains shall be connected through the curb or into the gutter section of the street.
(B) Building downspouts pipe outlets and sump pump pipe outlets shall discharge on a pervious area of the lot with the following conditions:
(1) Downspout and sump pump pipe outlets that discharge water in an area of the building lot that does not flow in the direction of the public street right-of-way must extend at least five feet (5') from the building foundation and may extend more than ten feet (10') from the building foundation wall but not to an area where it will direct water into an area within five feet (5') of structures or improvements on adjoining properties or causes standing water on the building lot or adjoining properties. Downspout outlets placement for any structure in use at the adoption of Ordinance 2013-24 may continue as long as the downspout outlet satisfies the placement requirements in force at the time the structure was built.
(2) Downspouts and sump pump pipes outlets shall not discharge onto non-pervious areas (driveways, sidewalks, etc.) that flow onto or toward the public street right-of-way unless such discharge is unavoidable due to the structure's design or other zoning or building requirements. In such instances, no more than 20% of a roof may drain onto a non-pervious surface.
(3) Downspout and sump pump pipes outlets shall not discharge directly into the public street right-of-way.
(4) Property owners who do not meet these requirements shall have one hundred and eighty (180) days to bring their property into compliance or seek an appeal for deviation from these standards as required in section § 93.04.
