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. 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/sufbmp-manual). ❑ Please submit a Level Spreader Supplement Form with all required items for each proposed level spreader (see ht4):Hportal.ncdenr.org/web/wq/ws/su/bmp-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/su/bmp-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/cemandpermits/swmanagement). For each proposed BMP, please provide a completed BMP Supplement Form with all required items (see http://portal.ncdenr.org/web/wq/ws/swbmp-manual). ❑ [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.nedenr.org/web/wq/ws/su/bmp- manual). ❑ Please use the most current version of the BMP Supplement Form (see: htq)://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 the proposed buffer impacts. Please submit a mitigation plan detailing the amount of buffer impact for Zone 1 and/or 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). 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 cation sign ❑ Pleas, ed for this F, ❑ Pleas L1 nuary 200V load this fi i.usace.arr vilc ❑ Pleas I� ti t l�t�c�i"t�ia AV (TIFI 4or)) along ❑ Pleas �fik_�, %:he site (uF Fig aested. identi lA l�,.,n j r 00C(� ❑ Pleas Tt 111 �}� ! !t analysis _ _ d _ ap ii _ e on our 1/ olicies }� ❑ For aJ rer basins `I�o w `� j .,tate that tlt establish t; ❑ Pleas + Form.
