This report summarizes our findings for the site. PROJECT UNDERSTANDING The 78-acre project site is located southeastern quadrant of the intersection of interstate 1-85 and Long Ferry Road in Salisbury, North Carolina. We understand the site is being developed with an approximate 690,500 sq-ft industrial building, stormwater pond, associated parking and drive areas, and three (3) retaining walls. ECS has been requested to determine the SHWT depth within the stormwater control measures (SCM), proposed as part of the stormwater management plan. A proposed boring location layout, overlaid onto an aerial photo was utilized as a background to display the boring locations (Figure 1), which is in general proximity to the proposed SCM(s). The soil investigation was conducted via drill rig and split spoon. SCOPE OF SERVICES ECS conducted a study/investigation of the soils to identify the depth of the seasonal high water table, if present. The properties and characteristics of the soils retrieved from the boring were observed and recorded in field notes. The properties include texture, depth, the presence of restrictive horizons, depth to seasonal high water table, coarse fragments, etc. The assessment was conducted in accordance with current soil science practices and technology.

SHWT Boring 1 — The surface layer to a depth of approximately 4 inches below round surface (bgs) was brown sandy loam with weak, fine, granular structure. The subsurface layer from approximately 4 inches bgs to approximately 108 inches (-9 feet) bgs was clay to clay loam with moderate, fine, sub -angular blocky structure. The consistence was sticky, plastic, and firm. The subsurface layer from approximately 108 inches bgs to approximately 240 inches (-20 feet) bgs was multi -colored sandy clay loam to sandy loam saprolite. SHWT Boring 2 — The surface layer to a depth of approximately 2 inches below round surface (bgs) was brown sandy loam with weak, fine, granular structure. The subsurface layer from approximately 2 inches bgs to approximately 80 inches bgs was clay to clay loam with moderate, fine, sub -angular blocky structure. The consistence was slightly sticky, slightly plastic, and firm. The subsurface layer from approximately 80 inches to approximately 114 inches (-9.5 feet) bgs was multi -colored sandy clay loam to sandy loam saprolite. FINDINGS SHWT Boring 1 — Indicators of a SHWT were noted at approximately 180 inches (-15 feet) bgs. Water was noted at approximately 210 inches (-17.5 feet). SHWT Boring 2 — Indicators of SHWT were not identified to a depth of approximately 114 inches (-9.5 feet) bgs. Auger refusal was met at approximately 114 inches bgs. The type of stormwater management facility designed is based on the depth of the SHWT or confining layer. The information above may be potentially utilized to determine the type of stormwater management facility best suited for this site according to the most recent version of the North Carolina Division of Water Quality Stormwater Best Management Practice Manual.
