INTRODUCTION This Soil and Site Reconnaissance was performed on approximately 15-acres (referred to as Austin Tract North ) of an 0.7-acre tract of land located on Lawyers Road East, Marshville, North Carolina (Union County Tax Parcel Number: 0216700). Thompson Environmental Consulting, Inc. (TEC) was retained to determine whether the property is suitable for the placement of an onsite subsurface wastewater septic system. The property was evaluated in accordance with North Carolina statutes for waste disposal ( Laws and Rules for Sewage Treatment and Disposal Systems, amended July 1, 2016). INVESTIGATION METHODOLOGY & SITE DESCRIPTION Soil borings were advanced with a hand auger and soil color was determined with a Munsell Soil Color Chart. Observations of the landscape (slope, drainage patterns, etc.) as well as soil properties (depth, texture, structure, seasonal wetness, restrictive horizons, etc.) were recorded. Each soil boring was located using a hand-held GPS unit with sub-meter accuracy. The property evaluated is currently undeveloped. Property boundaries and depressional features are vegetated with a mixed deciduous forest with the majority of the acreage being used primarily for agricultural production. FINDINGS A field survey was conducted on November 29, 2016, by Larry Thompson, LSS. Thirteen (13) soil borings were advanced, logged, and their locations noted on Figure 1. Two (2) soil borings (Soil Borings 1 and 2) were rated as Provisionally Suitable for shallow-placed conventional or accepted system types. These soils typically exhibited friable, silty clay loam textured surfaces with weak, medium, granular structure ranging in depth from 3 to 6 inches. Subsurface horizons exhibited firm, silty clay textures with weak to moderate, medium, subangular blocky structure ranging in depth from 29 to 39 inches before encountering saprolite. Soil Boring 11 was 22 inches in depth and, while provisionally suitable for septic, would not be deep enough to support the system types referenced. Soil Boring 11 would be better suited for a low-profile chamber or drip dispersal system. A range in the long-term acceptance rate (LTAR) of 0.25 to 0.3 gal./day/sq. ft. would be recommended for Soil Borings 1 and 2. Ten (10) soil borings were rated as Unsuitable for wastewater treatment and disposal. These soils typically exhibited friable, silty clay loam textured surfaces with weak, medium, granular structure ranging in depth from 3 to 6 inches. Subsurface horizons exhibited firm, silty clay textures with weak or moderate, medium, subangular blocky structure ranging in depth from 6 to 12 inches before encountering soil wetness indicators or rock. DISCUSSION The soil unit rated as Provisionally Suitable for shallow-placed conventional or accepted system types is depicted as a green polygon in the attached Figure. It is estimated that 10,000 to 12,000 sq. ft. of 2+ inch deep Provisionally Suitable Soil will be needed to support an initial system and repair area for a four-bedroom home.

The area of usable soil is estimated to be 9,000 square feet or less. Additional work would be required to determine the exact square footage of usable soil and the number of bedrooms that this area would support. CONCLUSION The findings presented herein represent TEC s professional opinion based upon our Soil and Site Reconnaissance and knowledge of the current laws and rules governing on-site wastewater systems in North Carolina. Soils naturally change across a landscape and contain many inclusions. As such, attempts to quantify them are not always precise and exact. Due to this inherent variability of soils and the subjectivity when determining limiting factors, there is no guarantee that a regulating authority will agree with the findings of this report. This report does not guarantee or represent approval or issuance of Improvement Permits, which can only be authorized by Union County Environmental Health.
