(a) The stormwater management concept plan (stormwater plan) shall utilize to the maximum extent practicable site planning and design techniques that reduce runoff rates, volumes, and pollutant loads. Such techniques include, but are not limited to, minimization and/or disconnection of impervious surfaces; development design that reduces the rate and volume of runoff; restoration or enhancement of natural areas such as riparian areas, wetlands, and forests; and distributed practices that intercept and treat runoff from developed areas.
(b) The stormwater plan shall be presented as follows:
(1) Through plans, illustrations, reports, and calculations, the stormwater plan shall display the required information specified in the guidance manual.
(2) The stormwater plan must be sufficiently detailed to specify the type, location, and size of stormwater management facilities, using preliminary calculations. Detailed construction drawings are not required at the stormwater plan review stage.
(3) If it is proposed to develop a parcel in two or more phases, the stormwater plan shall be prepared and submitted for the total project.
(c) Plan preparation. The Stormwater plan shall be prepared by a designer in accordance with the requirements outlined in the city's post construction stormwater management guidance manual. Other persons and professionals may assist in the preparation of the plan. All plans shall be properly sealed.
