Plan Detail Incomplete
? Please locate the project boundaries on the most recent bound and published Wake County soil survey and the USGS
1:24,000 topographic map for the project.
Please re-submit your site plans on full plan sheets at a scale of no smaller than 1 "=50' with topographic contours
shown.
? 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
Desi , 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.
Avoidance and Minimization
? The labeled as on the plans does not appear to be necessary. Please eliminate the
or provide additional information as to why it is necessary for this project.
? This Office believes that the labeled on the plans as can be moved or reconfigured to
avoid the impacts to the . Please revise the plans to avoid the impacts.
? This Office believes that the labeled on the plans as can be moved or reconfigured
to minimize the impacts to the . Please revise the plans to minimize the impacts.
? Your proposed stream crossing appears to be aligned at approximately . Please re-configure your proposed stream
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 (see http://portal.ncdenr.org/web/wq/ws/su/bmp-manual).
? Please submit a Level Spreader Supplement Form with all required items for each proposed level spreader (see
http://portal.nedenr.org/web/wq/ws/stVbmp-manual).
? 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
TN and TP. For each proposed BMP, provide a completed BMP Supplement Form with all the required items
(http://portal.ncdenr.org/web/wq/ws/suibmp-manual).
? 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.
? [Drainage Area Map and Percent Imperviousness Breakdown]
? Please delineate the drainage areas on the site plan (Drainage area map on full plan sheets)
? 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.
? [High Density] Per the requirements of GC , this project is subject to Stormwater Management Plan (SMP) Requirements
for Applicants Other Than the North Carolina Department of Transportation (see
http://portal.ncdenr.org/web/wq/swp/ws/401/certsandpermits/swmanagement). For each proposed BMP, please provide a completed BMP Supplement
Form with all required items (see http://portal.ncdenr.org/web/wq/ws/su/binp-inanual).
? [Low Density] Per the requirements of GC , this project is categorized as low density. For each vegetated stormwater
conveyance, please provide a completed Low Density Supplement Form along with all supporting information (see
http://portal.ncdenr.org/web/wq/ws/su/bmp-manual).
? Please provide a BMP Supplement Form with all required items for every BMP on the site (see http://portal.ncdenr.org/web/wq/ws/su/bmp-
manual).
? Please use the most current version of the BMP Supplement Form (see: http://portal.ncdenr.org/web/wq/ws/su/bmp-manual).
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 all road crossings that impact 150 linear feet of riparian buffer or more. Please submit a
mitigation plan detailing the amount of buffer impact at crossing and how the impact will be mitigated.
? Please provide documentation from 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 VIII, No. 2.
Other
? The application fee is insufficient because over 150 feet of stream and/or over 1 acre of wetland impacts were requested. Please
provide $ . This additional fee must be received before your application can be reviewed.
? Please provide a signed copy of the application.
? Please provide an agent authorization letter for the application signature.
? Please indicate which 404 Permit the USACE has authorized for this project.
? Please provide copies of the application, copies of the site plans or other supporting documentation.
? Please resubmit copies of your information on the January 2009 PCN form or a more recent version. You can download
this format the following web address: (see http://www.saw.usace.army.miI/WETLANDS/pcn/)
? Please submit electronic CAD files showing , via email to [e-mail] and provide a CD
(TIFF Group 4 format (black and white, not grayscale or color)) along with your response to the additional information requested.
? Please provide stream determination documentation on the site (upstream and downstream photos and DWQ stream
identification forms).
? Please provide a qualitative indirect and cumulative impact analysis for the project. Please see DWQ's policy for guidance on
our website at: http://portal.ncdenr.orp,/web/wq/swp/ws/40 I /policies
? For areas in nutrient sensitive waters (NSW) or buffered river basins fertilizer specifications for stormwater BMPs should state
that that only an initial minimal application of fertilizer to establish the plants shall be used.
? Please complete Section of the PCN Form.
? Please provide proposed septic fields on all (or) lots showing that additional impacts will not be
required.
