§ 74-304. Stream crossing requirements.

Construction or repair of structures that cross streams, including but not limited to those exempt under section 74-305, shall be subject to the following:

(a)

A hydraulic analysis prepared, signed, and sealed by an engineer registered to practice in the State of Georgia is required for any proposed stream crossing. The analysis shall demonstrate that the proposed crossing will not adversely impact upstream and downstream properties during a 100-year flood; and

(b)

Free-span techniques shall be employed to prevent blockage or constriction of natural drainage ways; and

(c)

Approximately perpendicular crossing angles shall be employed; provided, however, crossings shall be aligned to minimize buffer disturbance to the maximum extent practicable; and

(d)

Best management practices shall be utilized, stream banks shall be properly stabilized, and buffers shall be vegetated in accordance with the City of Atlanta Buffer Revegetation Guidelines.
