§ 1138. Structural stormwater controls.

(a)

All structural stormwater management facilities shall be selected and designed using the appropriate criteria from the Georgia Stormwater Management Manual (GSMM).

(b)

All structural stormwater controls shall be appropriately designed to meet the intended function.

(c)

The effectiveness and pollutant removal of the structural controls must be documented through prior studies, literature reviews or other means and be approved by Jackson County prior to being included in the design of a stormwater management system. This standard shall apply to other structural stormwater controls not included in the GSMM, or those for which pollutant removal rates have not been provided. In addition, whenever hydrologic or topographic conditions or land use activities warrant greater control than that provided by the minimum control requirements, Jackson County may impose additional requirements. Such requirements shall be those deemed necessary to protect upstream and downstream properties and aquatic resources from damage due to increased volume, frequency and rate of stormwater runoff or increased nonpoint source pollution loads created on the site.

(d)

Applicants shall consult the GSMM for guidance as concerns the factors that determine site design feasibility when selecting and locating a structural stormwater control.
