stormwater facilities that are considered to remove nitrogen and phosphorus.
Additionally, a stormwater management plan for this project shall provided to this Office

Disturbed areas with pre-existing grassed lawns must be replanted with grass. Disturbed
areas with pre-existing trees or woody vegetation must be replanted with trees and
woody vegetation. Disturbed areas with pre-existing forest vegetation must be replanted
with forest vegetation including at least two different native hardwood tree species at a
density sufficient to provide 260 trees per acre at maturity. This density can usually be
achieved by planting approximately 360 (11 x 11 spacing) to 538 (9 x 9 spacing) trees per
acre.) Restoration of trees/shrubs/forest must be completed by the first subsequent
planting season (November 1 through March 30). Note, if the tree plantings do not
survive, they will need to be replaced such that the density is sufficient to provide 320
trees per acre at maturity. [15A NCAC 02H .0507 (c), 15A NCAC 02H .0506 (b)(3), and 15A
