? Please provide cross section details showing the provisions for aquatic life passage.
? Please provide building envelopes for all lots with wetlands, streams or buffers (or lots ) on the site plans.
? Please indicate proposed lot layout as an overlay on the site plan.
? Please provide a signed and sealed geotechnical report of subsurface soils at the proposed bottomless culvert location. The
report must comply with the Division of Highways - Guidelines for Drainage Studies and Hydraulic Design, prepared by A.L.
Hankins, Jr., State Hydraulics Engineer - 1999.
? Please locate any planned sewer lines on the site plan.
? Please provide a detailed planting plan for (standard format includes: scientific name, common name,
source of the plant material, plant spacing, wetland indicator status, etc., as well as planting specifications).
? Please indicate all proposed stream or wetland driveway crossings on your plan sheet (including future proposed).
? Please indicate all stream impacts including all fill slopes, dissipaters, and bank stabilization on the site plan.
? Please indicate all wetland impacts including fill slopes on the site plan.
? Please enumerate all riparian buffer impacts on the site plan and clearly label impacts (Buffer Impact 1, etc.).
? Please locate all isolated or non-isolated wetlands, streams, and other waters of the State as overlays on the site plan.
? Please locate all of the protected riparian buffers as overlays on the site plan, clearly showing Zone 1 and Zone 2.

Diffuse Flow and Stormwater
Per the requirements of the 8 W Sc_-_, 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 (see ht );h2o.enr state nc nvbmp f6rms.htrn).
? Please submit a Level Spreader Supplement Form with all required items for each proposed level spreader (see
hup h2o er1nst,a IICJW ubnlli_for"s lrin,).
? 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 level spreaders (6% for wooded vegetation and 8% for thick ground cover and grass). 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 85 percent TSS
and 30 percent TN and TP. For each proposed BMP, provide a completed BMP Supplement Form with all the required items
(see httn:r: h2o_et,r.state_uc.us w'bmk farm litm).
? Please provide calculations to show the outlet velocity from outlet(s) to the wetland(s). A non-erosive
velocity of two feet per second or less must be achieved for the peak flow from the 10-year storm.

1J0?,? [Pockets of High Density] Please provide an inventory of imperviousness surfaces in each drainage area. The inventory should
include all proposed building footprints, roads, driveways, sidewalks, gravel-surfaced areas, amenity areas, etc. A Stormwater

provide a completed BMP Supplement Form with all the required items (see nttt n2o.enr sta?e.uc.us stu'h„foirm.1,ti„). Per NCAC 2B
15A: 02H.1000, a "drainage area" is defined as "the entire area contributing surface runoff to a single point."
? Please provide a BMP Supplement Form with all required items for every BMP on the site (see ,1, t(,,r,s.r,tt„)_
