SITE DESCRIPTION: The site is a gently sloping (2%+-), cleared site previously possibly used for agricultural purposes in the past. No improvements are present on the site. Soil types on this site consist of predominantly Norfolk loamy sand (No). The Seasonal High Water Table was estimated at 36" below the ground surface in the area to be utilized for treatment. A soil report with Ksat infiltration results is attached. There are no wetlands or streams located on the property PROPOSED PROJECT The proposed project consists of the construction of a 5,000 SF single story building and associated paved parking. The total disturbed area is approximately 1.6 acres. The project includes site building sewer to on -site septic disposal and water tap for water. The front half (south and bulk of development area) of the site drains into the existing state road ditch and the property to the south east where it eventually discharges into the Upper Little River in the Cape Fear basin. The back half of the site (north and predominantly the septic disposal area) of the site drains overland across adjacent property (same ownership) to a natural swale and eventually to the Upper Little River. An offsite area drains to the site from the west (approximately 1.2 ac.) and is currently or intermittently cultivated farm land. Runoff from this area will be collected, treated, and discharged from the site. Stormwater Management - In accordance with NCDNR's interactive map, this site is subject to state Phase II water quality treatment regulations. E STORMWATER MANAGEMENT MEASURES: The soil analysis of the site in the area to be utilized for treatment indicated low Ksat infiltration rates (0.29 in/hr). This infiltration rate is below the threshold for an infiltration BMP. The SHWT was estimated at 36" below the ground surface. This depth combine with the relative low elevation differential across the site rendered a Bioretention BMP to be impractical. A stormwater wetland is proposed which will meet the Phase II treatment and discharge control requirements. The proposed wetland has been sized to accommodate the on and off site drainage areas and routing is attached showing no increase in the discharge for the 1 year - 24 hour storm in accordance with the Phase II requirements. The basins are capable of containing the expected runoff volume from the 1, 2, 10, 25-yr storms without increased discharge to surface waters. An analysis point was chosen at the south west corner of the site where discharge occurs from a combination of the existing DOT roadway ditch and the proposed wetland outlet.

The purpose of the investigation was to determine soil water table depths (SI-1 WT) based on soil profiles. In addition, Ksat was to be provided at a depth 2.0 feet above the SH WT elevation for use with stormwater retention basin design. Saturated hydraulic conductivity of the unsaturated zone was measured in a similar method as described in the Soil Science Society of America Journal, Vol. 53, no 5, Sept. - Oct. 1989, "A Constant Permeameter for Measuring Saturated Hydraulic Conductivity of the Vadose Zone" and Comparison of the Glover Solution with the Simultaneous Equations Approach for Measuring Hydraulic Conductivity." This consists of advancing a small diameter bore hole to a predetermined depth (typically 2 feet above SHWT). At this depth, a constant head (pressure) was established and maintained. Flow measurements were made at timed intervals after flow stabilized. Soils at the proposed basin site are most similar to the Norfolk soil series (see attached boring log). Two borings were advanced to 8.0 feet. Seasonal High Water Table (SI-I WT) as determined by evidence of colors ol'chroma 2 or less (and/or concentrations of high redox mottles) was encountered at a depth of 36 inches below the ground surface. SOIUSITE EVALUATION • SOIL PHYSICAL ANALYSIS • LAND USEISUBDIVISION PLANNING GROUNDWATER DRAINAGE/MOUNDING • SURFACE/SUBSURFACE WASTE TREATMENT SYSTEMS, EVALUATION 8 DESIGN Two compact constant head permeameter (CCHP) tests were Conducted at it depth of 1.00 feet below the ground sttrfitce. The measured Ksat rate in boring I was 8.05 em/hr (equivalent to 3.17 inches/hour). The measured Ksat rate in boring 2 was 0.73 cm/hr (equivalent to 0.29 inches/hour). fhe attached map shows locations of the sample points as well as Ksat location. It should be noted that the reported SH W"f does not necessarily reflect the elevation of static groundwater (due to variations in groundwater recharge rates. annual rainfall_ drought conditions, etc.). The data presented in this report are limited by a number of considerations. The primary consideration is that soil formations can be highly variable. The sails found on this site can be subject to inclusions of other soil types; perched water. artesian conditions and/or layers of undulating low permeability clay seams. These and other soil conditions can have an affect on the steady state of groundwater flow. To the extent possible, we have identified the soil types that will impact the flow of groundwater, and have provided a professional opinion as to the depth of SII WT. I trust this is the information you require at this time. Sincerely, �Zz�y Mike Eaker NC Licensed Soil Scientist #1030 "D Soft pEL 0, Southeastern -Soil &-Enviro mental -Associate: P.O.

PE 6131 Falls of Neuse Road Suite 300 Raleigh, NC 27609 Re: Preliminary soil evaluation for subsurface waste disposal, +/- 2 acre combined tract (PID 010524 0018 & 010524 0018 19, Raynor Road, Harnett County, North Carolina Dear Mr. Smith, A preliminary soils investigation has been completed for the above referenced tract at your request. The property is located on Raynor Road as illustrated on the accompanying map. The purpose of the investigation was to determine the extent of soil areas that may have the ability to support a subsurface waste disposal system for a proposed church facility [total facility flow of 720 gallons per day; up to 240 sanctuary seats u 3 gallons per seat per day; no fellowship hall]. All ratings and determinations were made in accordance with "Laws and Rules for Sanitary Sewage Collection, Treatment, and Disposal, 15A NCAC 18A .1900". Southeastern Soil and Environmental Associates, Inc. (SSEA) performed these soil evaluations in February, 2012. SSEA traversed the property and observed landforms (slope, drainage patterns, etc.) as well as soil conditions through the use of hand auger borings and/or soil probes. Soils on this site are dominantly suitable or provisionally suitable for a subsurface waste disposal system to serve the proposed facility. Typically, these soils exhibited 10 or more inches of fine loamy sand underlain by sandy clay loams to depths of 48 or more inches. Soil wetness, depth, and mineralogy were typically provisionally suitable to depths of at least 36 inches. A 720 gpd church facility would require approximately 12,000 sq.11. of this soil area for drainfields and repair areas (exclusive of setbacks from lot lines, facilities. etc.). (Note: These square footage recommendations assume appropriate SOIL/SITE EVALUATION • SOIL PHYSICAL ANALYSIS • LAND USE/SUBDIVISION PLANNING GROUNDWATER DRAINAGE/MOUNDING • SURFACE/SUBSURFACE WASTE TREATMENT SYSTEMS, EVALUATION & DESIGN topography for a practical septic system layout on topographical contour. Space requirements could increase with difficult topography, irregular lot lines, etc.) The initial septic system in these soil types would require a 1,500 gallon septic tank with a conventional drainlield (GOO linear leet of conventional drainline based on an [A -Alt of 0.4 gpd/sq. ft. installed on contour). Note: Any site grading or soil removal in these suitable or provisionally suitable areas may alter the findings of this report and render sites unusable. Areas for septic disposal must remain undisturbed (no mechanical clearing, stripping, excavation or heavy traffic). Southeastern Soil and Environmental Associates, Inc. is pleased to be ofservice in this matter. We look forward to assisting in additional site analysis or septic design needs you may have in the future. Please feel free to call with any questions.

Numbers in parenthesis are PF estimates at lower and upper bounds of the 90 % confidence interval. The probability that precipitation frequency estimates (fare given duration and average recurrence interval) will be greater than the upper bound (or less than the lower bound) is 5%. Estimates at upper bounds are not checked against probable maximum precipitation (Pi estimates and may be higher than currently valid PMP values.
