crossing to show it aligned approximately perpendicular (between 75° and 105°).
Diffuse Flow and Stormwater
^ Per the requirements of the Riparian Buffer Rule, you must show that this site meets diffuse flow requirements
with a level spreader or other BMP per Chapter 8 of the BMP Manual (gee httpriportai.n~aenr.org/wet~wq/w9/soromp•manaan.

^ Please show contour lines down slope of the level spreader to show that it-has been correctly sited per the BMP Manual.
^ The slope from the proposed level spreader(s) lip ( ) to the top of bank of the stream exceeds the allowable
slope for type of vegetated filter strip (5% for riparian buffer VFS, and 8% for. engineered filter strip). You must either relocate
the level spreader(s) to a location where the filter strip slope(s) is/are appropriate or provide a BMP that removes 30 percent

(htlp://portal.ncdenr.org/web/wq/wslaulbmp-manual).
^ Please provide calculations to show the outlet velocity from outlet(s) to the wetland(s). Anon-erosive
velocity of two feet per second or less must be achieved for the peak flow from the 10-year storm.

^ Please provide the overall percent imperviousness of the project, and an inventory of impervious surfaces in each
drainage area. The inventory should include all proposed building footprints, roads, driveways, sidewalks, gravel-
surfaced areas, amenity areas, etc.

Mitigation
^ of compensatory mitigation is required for this project. Please provide a compensatory
mitigation plan. The plan must conform to the requirements of 15A NCAC 2H .0500 and must be appropriate to the type of
impacts proposed.
^ Buffer mitigation is required for the proposed buffer impacts. Please submit a mitigation plan detailing the amount of buffer
impact for Zone 1 ancUor Zone 2 and how the impact will be mitigated.
^ Please provide documentation from an appropriate mitigation bank or the NCEEP indicating their willingness to accept your
request to purchase (type of mitigation) credit to mitigate for the proposed
(type of mitigation) impacts listed in your PCN application per Section D. Mitigation provider selection must conform to the
requirements of G.S.143-214.11(for wetland and stream mitigation) or G.S. 143-214.20 (for riparian buffer mitigation).

1. Please be advised that the stormwater ponds shown on the plans will need to be wet
detention ponds in order to meet the pollutant removal requirements on this site.
2. Please provide a BMP Supplement Form for each proposed wet detention pond and each
proposed level spreader-vegetated filter strip that will be used on the site (a total of four
separate supplement forms). Each supplement form must include both worksheets,
Design Summary and Required Items Checklist), as well as all of the required items.
Failure to provide the forms with ALL of the required items in the next submittal will
result in a return of application.
3. The BMP Supplement Forms must be obtained from the DWQ web site at:
http://portal.ncdenr.or web/wq/ws/su/bmp-manual.
