Box 1132 w Charlottesville,VA 22902 + Z s c (fire Z) Sa.tic�-u a r y, #04.1, .hoc icc,' Re: Soil Investigation for Septic System Chapman Grove Baptist Church Albemarle County Gt S k, , sr„„,,c‘--c a.,c,1-u.4-t/ 14c: A►,,,ll Dear Mr. von Storch: As requested we have performed a soils investigation on the above-referenced property. The purpose of the study was to determine how much area would be available for use as drain field for two proposed additions. We drilled five (5) test holes to determine soil profiles on the property. A log of each test hole is shown on the enclosed soil profile sheet. Information pertinent to the design of the drain field is on the soil information summary sheet. The approximate location of the proposed drain field areas is shown on the site plan. EXISTING CHURCH: The sanctuary currently has 16 benches with a seating capacity of 64. The choir has 24 seats. The attendance for Sunday morning activities during the August 2014 • ranged from 49 to 64(average attendance—56)from information provided us. The existing septic system was installed in 1974 and was permitted for 200 gallons per day (a copy of the permit is enclosed). During our investigation we did not observe any wet areas in the vicinity of the existing drain field. ADDITION#1: This addition will be located on the northeast side of the church and will add 28 seats to the sanctuary. ADDITION#2 (FUTURE): .. This addition will be located on the southeast side of the church and will add an additional 28 seats to the sanctuary along with a social hall and kitchen facilities. A portion of the existing drain field will be under or within 10 it of Addition #2. The drain field will be to be abandoned. war rn '04,450, taw rr SOILS INVESTIGATION: Based on our investigation there are several areas that could be used for future drain N.) field sites. These areas are shown on the enclosed site plan. It would be possible to design a conventional septic system (possibly using time dosing) in the vicinity of holes 1, 4 and 5 that would accommodate approximately 100-125 gallons per day. .. The 100%reserve drain field could consist of two deep pressure pads (one pad in the vicinity of holes 1 and 2 and a second pad in the vicinity of hole 3) with secondary treatment of the effluent. `, The existing gravel parking lot will have to be paved after the drain field is installed in order to meet current Health Department regulations. RECOMMENDATIONS: ADDITION #I: Provided the daily activities at the church remain the same (no pre- school or day care for example)the existing septic system will,in our opinion,handle Nur the increased water usage associated with Addition#1. ADDITION#2: Since Addition #2 will be built over a portion of the existing drain field a new septic system will be required. Since this addition will include a kitchen and social hall there could be a significant increase in water usage. If the projected water usage exceeds 100-125 gallons per day it will be necessary to design a septic system that 1)uses time dosing or 2) provides secondary treatment of the septic tank effluent(alternative/engineered septic system). We suggest that, if possible, a water meter be installed to monitor the actual water usage. This data would assist the engineer when he designs the septic system associated with Addition#2.
