(A) Design. The drainage system components, especially all detention basins, shall be designed to protect the safety of any children or adults coming in contact with the system during runoff events.
(B) Shorelines. The shorelines of all detention basins at 100-year capacity shall be as level as practicable to prevent accidental falls into the basin and for stability and ease of maintenance. Shorelines shall not have greater than three to one (horizontal to vertical) slope.
(C) Banks. The sideslopes of the banks of both wet and dry detention basins shall not be steeper than three to one.
(D) Safety ledge. All wet detention basins shall have a level safety ledge extending three feet into the basin from the shoreline and two feet below the normal water depth.
(E) Velocity. Velocities throughout the drainage system shall be controlled to safe levels taking into consideration rates and depth of flow.
(F) Overflow structures. All stormwater detention basins shall be provided with clearly defined overflow facilities capable of safely passing overflows so that downstream damage to properties is prevented.
