Re: Seasonal High-Water Table Identification: Blackburn,Phillipi Church Road,Hoke County NC parcel
494640001003
Soil conditions on the above-referenced property were evaluated within the area shown on the attached map
to determine the depth to the seasonal high water table. Work was conducted to satisfy requirements of the
North Carolina Department of Environmental Quality Stormwater Design Manual. Samples were collected
with a hand auger.
SEASONAL HIGH WATER TABLE IDENTIFICATION
Seasonal High Water Table depth is determined by field evaluation for soil wetness conditions which are
indicated by the presence of redoximorphic (redox) features with chroma colors of 2 or less (in Munsell
color notation) in mottles or the horizon matrix, and at times, saturated soil conditions and/or free water
within the soil profile. Colors of chroma 2 or less due to relic minerals from parent material (underlying
rock), anaerobic activity created by placement of fill material, or soil textural class transitions (perched
water) are not considered as indicators for seasonal high water.
The Seasonal High Water Table on this property was observed at elevation 146'
The SHWT information for the stormwater BMP devices are reported in the table below.
