Permanent structural and/or nonstructural BMPs shall be implemented to control and minimize stormwater runoff rates and volumes and to prevent, control, and minimize stormwater pollutants as required in this Chapter.
(a) It is a violation for any owner to improperly construct or operate or fail to maintain the proper function of privately owned structural BMPs. Maintenance activities include, but are not limited to, removing trash and debris, reseeding, mowing, pest control, removing sediment accumulation, removing vegetation, replacing filter media, and repairing eroded areas.
(b) It is a violation for any owner to place or deposit debris, yard waste, garbage, or other materials that are incompatible with BMPs (e.g., toys, sports equipment, decorative materials) in BMPs, or permit such items to be deposited in any manner on privately owned structural BMPs.
(c) The owner shall immediately notify the public works department of any discharge of a pollutant, debris, yard waste, garbage, excessive sediment, or materials incompatible with BMPs, including from a privately owned BMP, into the municipal storm water drainage system, when such discharge causes or is likely to cause obstruction of stormwater inlets, impairment of the flow of stormwater in city conveyances such as streets or gutters, or release of debris or chemical or biological materials into the municipal stormwater system. This notification shall include the location of the discharge, type of pollutant, concentration and volume, if known, and corrective actions taken by the owner. The owner shall document and submit to the public works department all pertinent information.
(d) In the case of any physical failure, including, but not limited to, structural, equipment, or media failure (e.g., failure of BMP fixtures including, but not limited to, screens, riprap, aerators, design features, and fences) of a privately owned structural BMP that may cause pollutants to enter the municipal stormwater system, the owner shall immediately notify the public works department of the incident. This notification shall include the location failure, type and extent of the failure, if known, and corrective actions taken by the owner. The owner shall document and submit to the public works department all pertinent information.
If privately owned BMPs are constructed, operated, and/or maintained in a manner that results in discharge of pollutants to the city's storm water drainage system, the director of public works may require the owner to implement additional structural and/or nonstructural BMPs to prevent the further discharge of pollutants to the storm water drainage system.
