Erosion Control Plan Checklist for TIP Projects
Guilford 7 WBS-176P.7.C17
COUNTY DIVISION LET DATE TIP
RIVER BASIN(S): Cape Fear
Water Quality Checklist*
Are any streams on the project classified as High Quality Water (HQW) or Critical Area (CA)? No ��
(North Carolina Water Quality classification of HQW, ORW, WS-I, WS-II, SA, PNA or CA)
Are there any Trout streams on the project? No �`
(Trout Waters are DWQ designation of Tr, or identified by NCWRC as Trout)
Are there streams/rivers with Riparian Buffer Rules on the project? vEs ��
(Neuse, Tar-Pamlico, Catawba (Main Stem), Randleman or Jordan Lake Watersheds)
Are impacted streams on the 2014 Final 303(d) list for Turbidity impairment? No �
See 2014 North Carolina 303(d) Final List
Are there endangered species sensitive to sediment present? No �
(Dwarf Wedgemussel, Carolina Heelsplitter, Cape Fear Shiner, etc.)
*- For "YES" responses to any of these 5 questions, all jurisdictional streams on the project
will need a 50-ft. Environmentally Sensitive Area (ESA) hatched on both sides of stream.
Erosion Control Plan Checklist

(25-yr storm for HQW, Trout, Riparian Buffers, 303d for turbidity, or endangered species)
Design calculations for sediment basins and checkdams included in Submittal? vEs ��
See Basin and Checkdam Designer Spreadsheets on Soil & Water Engineering Downloads Page
Environmentally Sensitive Area (ESA) applied to streams and rivers? YES
(ESA is a 50-ft. hatched area on both sides of stream to ROW or Easement (25-yr design))

MAP INFORMATION
The soil surveys that comprise your AOI were mapped at
1:20,000.
Warning: Soil Map may not be valid at this scale.
Enlargement of maps beyond the scale of mapping can cause
misunderstanding of the detail of mapping and accuracy of soil
line placement. The maps do not show the small areas of
contrasting soi�s that cou�d have been shown at a more detailed
scale.
Please rely on the bar scale on each map sheet for map
measurements.
Source of Map: Natural Resources Conservation Service
Web Soil Survey URL:
Coordinate System: Web Mercator (EPSG:3857)
Maps from the Web Soil Survey are based on the Web Mercator
projection, which preserves direction and shape but distorts
distance and area. A projection that preserves area, such as the
Albers equal-area conic projection, should be used if more
accurate calculations of distance or area are required.
This product is generated from the USDA-NRCS certified data as
of the version date(s) listed below.
Soil Survey Area: Guilford County, North Carolina
Survey Area Data: Version 14, Sep 19, 2016
Soil map units are labeled (as space allows) for map scales
1:50,000 or larger.
Date(s) aerial images were photographed: Feb 11, 2011—Mar 3,
2011
The orthophoto or other base map on which the soil lines were
compiled and digitized probably differs from the background
imagery displayed on these maps. As a result, some minor
shifting of map unit boundaries may be evident.
