(AGI) has prepared this Soil Suitability and Nitrate Loading Study (Study) for the property located at 9128 South Priest Road, French Camp, California (site or subject property). The purpose of this Study is to determine the potential impact from nitrate loading and the suitability of the subsurface for an onsite wastewater treatment system (OWTS) due to the proposed development of an accessory dwelling unit (ADU), a septic system, and the future use of the property.

The scope of work included a soil percolation test, groundwater sampling of the onsite domestic water well, review of published soil and groundwater information, local septic use and permit research and estimated nitrate impact to soil and groundwater at the site. The site and surrounding area are illustrated in Figure 1. A site plan depicting structures, the percolation test hole location, and the planned location of the proposed ADU and septic system are illustrated in Figure 2. 1.1. DESCRIPTION OF SITE The location of the site, surrounding properties and general setting is illustrated on the Stockton West topographic map (7.5 Minute United States Geological Survey (USGS) Topographic Series, California).
