[1] INTRODUCTION F!ubility Study presents the results of our investigation concerning the surface and onditions under the above-referenced subject property. Our study was completed as qy Environmental Health Department to 1.) Conduct percolation testing in the area of the proposed leachfield that will serve the Mohler's future residence and be in compliance with Environmental Health Department regulations, and 2.)Ensure that the new parcel being created by Lot Line Adjustment will provide adequate and acceptable effluent management by a septic system that will function properly for its anticipated lifespan. Recommendations have been provided in this study based upon the San Joaquin County Sewage Standards and the environmental criteria encountered. Since there is no well on the subject property, other than an old irrigation well that is unusable without PTO power, on-site water was not analyzed for nitrate or the agrichemical DBCP/EDB. Our report meets the requirements for a Soil Suitability Study as required for this project under Development Title Section 9-1105.2 Item(d) of the San Joaquin County Ordinance Codes. [2] SUBJECT SITE AND STUDY AREA BACKGROUND INFORMATION The project consists of a Lot Line Adjustment whereby a "flag lot" that was created in the early 1990's in the back of the parcel is proposed to be moved next to Mohler Road, as illustrated on the attached Site Plan Map. The subject property is currently zoned AG40 and is to consist of two Parcels: Parcel I is the homesite parcel proposed to be 1.30 acres. Proposed Parcel 2 is to consist of 17.79 acres. Both Parcel 1 and Parcel 2 are currently planted completely in cherries which were originally flood irrigated, but are now micro-sprinkler irrigated. Therefore,there is virtually no possibility of disposal field inundation from irrigation water. The Site Plan illustrates the designations and orientation of the subject Parcels. A second unit dwelling will not fit on Parcel 1. The topography of the site is flat; therefore, no design criteria for slopes will have to be incorporated into a new septic system, or for a possible repair. On-site stormwater percolates into the floor of the cherry orchard. Drainage cannot encroach onto Mohler Road because of a three- foot elevation difference between the floor of the orchard and the road. The property is located directly east of the town of Ripon. The study area consists predominately of agricultural production land - primarily orchards,row crops, vineyards and nursery production. Surrounding structures west of Mohler Road consist of low density single family housing, residential ranchettes, barns and other types of agricultural buildings. East of Mohler Road is a new residential housing subdivision. These houses are on City of Ripon sewer. A review of Application Permits on file with the San Joaquin County Environmental Health Department shows there has been no Application for Repairs/Additions to septic systems on Mohler Road. Considering that there has been no septic system repairs within the study area is indicative of the regional subsurface soils being favorable for long-term effluent management. The surface soils consist of a silty fine sand, which is consistent all the way down to the leachline depth of 42 inches. Soils found at the maximum leachline depth and the deeper soils possess excellent percolative capacity. This observation is based upon the percolation test results discussed below. 1 Chesney Cansuffi
