The purpose of the requirements in this section is to reduce the nitrogen loads from stormwater runoff within the Neuse River Basin, by implementing the Neuse Nutrient Strategy as defined in 15A NCAC 02B.0700 through .0711. The Neuse stormwater rules apply in all areas draining to nutrient sensitive waters within the basin, and to all surface waters within the city and its extraterritorial jurisdiction.
(A) Proposed development projects that would replace or expand existing structures and result in a net increase in built-upon area shall meet one of two options for the project less any existing built-upon area. The project shall meet either:
(1) A nitrogen stormwater loading rate target of 3.6 pounds per acre per year (lb/ac/yr) for the Neuse River Basin; or
(2) Meet "runoff volume match" as defined in this chapter.
(B) The developer shall determine the nitrogen load and loading rate generated from the project area without engineered stormwater controls and determine the needed nitrogen load reduction to meet nutrient targets by using the approved accounting tool.
(C) The nitrogen loading standards in this chapter are supplemental to, not replacements for, stormwater standards otherwise required by federal, state or local law, including without limitation any riparian buffer requirements.
