§ 74-216. Performance standards for stormwater management plans.

Stormwater management plans must demonstrate that the proposed development or activity has been planned and designed and will be constructed and maintained to meet each of the following standards:

(1)

Ensure that, after development or redevelopment, runoff from the site approximates the rate of flow, volume and timing of runoff that would have occurred following the same rainfall under existing conditions and to the extent practicable, predevelopment conditions, unless runoff is discharged into an off-site drainage facility as provided in section 74-218;

(2)

Maintain the natural hydrodynamic characteristics of the watershed;

(3)

Protect or restore the quality of ground surface waters;

(4)

Ensure that erosion during and after development or redevelopment is minimized;

(5)

Protect groundwater levels;

(6)

Protect the beneficial functioning of wetlands as areas for the natural storage of surface waters and the chemical reduction and assimilation of pollutants;

(7)

Prevent increased flooding and damage that results from improper location, construction and design of structures in areas which are presently subject to an unacceptable danger of flooding;

(8)

Prevent or reverse salt water intrusion;

(9)

Protect the natural fluctuating levels of salinity in estuarine areas;

(10)

Protect, insofar as possible, the integrity of natural interdunal trough groundwater recharge areas;

(11)

Minimize injury to flora and fauna and adverse impacts to fish and wildlife habitat;

(12)

Maintain the integrity of the right-of-way of all roads. To the extent that the driveway will not maintain any grade that will drain toward the driveway, toward the roadway, in both development and redevelopment;

(13)

Otherwise further the objectives of outlined in subsection 74-87(4)b.4.
