While the city/county of Brookings has requirements for design and pre-construction, post construction and maintenance regulations are from the state and federal level. Municipal stormwater resources can be found in the links below.
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.
(1) 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.
(2) It is a violation for any owner to place or deposit debris, yard waste, garbage, or other materials that are incompatible with the function of the BMPs, or permit such items to be deposited in any manner on privately owned structural BMPs.
(3) The owner shall immediately notify the city engineer 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 city's municipal storm water drainage 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 city engineer all pertinent information.
(4) 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 city's municipal stormwater system, the owner shall immediately notify the city engineer 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 city engineer 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 city may require the owner to implement additional structural and/or nonstructural BMPs to prevent the further discharge of pollutants to the city's storm water drainage system.
The design of all storm drainage systems and facilities shall conform to the Storm Drainage Design and Technical Criteria Manual. The Storm Drainage Design and Technical Criteria Manual may be viewed at the city engineer's office or on the City of Brookings website.
