Earnest F. Smith& Associates have been retained to determine if the proposed lot line adjustment is acceptable for a septic system, on-site, supporting a single family residence without any adverse environmental impacts. This report presents the findings of the study. INTRODUCTION & PROPOSED DEVELOPMENT SECTION The site is located 1300 feet south of east Woodbridge Road. 1320 feet east of Kennefick Road. The existing residence is located on APN: 017-100-21. The Property Detail shows the residence was constructed in I905.The site is currently located in a Federal FIood Insurance Administration Designated Flood Hazard Area. The 40 acre parcel consists of three lots and after the LLA, two lots will be 2 acres each in size and the remainder will be Parcel 1. (36 acres) The existing residence is located on Parcel 1. Parcel 2 and Parcel 3, as proposed, are vacant and are part of the existing vineyard. The site is located approximately 2000 feet north of the Calaveras River. The aoning is AG-40. PRESENT AND PAST USES OF THE SITE SECTION _ The parcels have been used for agricultural purposes. Present production is cherries and grapes. The SJC Agricultural Commissioner has furnished a record of chemicals used. These appear to be typical for grapes and cherries. The ag use will continue as these are established orchards and vineyards Some grape vines must be removed from Parcel 2 and 3 to allow construction of the residence and other improvements. The aerial photograph furnished by the former owner to Mr. Phillips (present owner) was taken about 1983, The land around the residence indicates ready for _ row crops or other plantings. The residence is approximately 100 years old. A large winery is located approximately 1300 feet to the west. The annual harvest of the grapes, at present, is sold for wine production. Grapes are planted to the south and east of the site. The general area is sparsely populated. EXISTING AND PROPOSED SEPTIC TANK USAGE SECTION The records at EHD, SJC were reviewed and are included in this report, for permits of record for any repairs of on site septic systems. Repairs were few. The winery at 5950 indicated a repair in 1990---two pits constructed. The winery has been expanding operations for several years and uses ponds in the operation process.At 6400 E. Woodbridge Road Parcel one is developed. Parcel 2 and 3 are vacant. Records were obtained from the EHD of permits issued for septic or wells in the area of study to determine any major problem evident in the area. The residence at 6400 E. Woodbridge Road was using a redwood septic tank which had to be replaced in 2004, according to the owner. The records indicate the tank was replaced in 2004.The leach field was not a problem and is still in use, shown easterly from the residence. Redwood septic tanks eventually rot out and there are few redwood tanks still in use. The record of repairs and well drilling _ records, as found, in the research at the EHD, SJC are included. Few repairs are needed in this locale, as the soil is non-plastic, fine textured and serves as a satisfactory medium for the clear effluent. Repairs on E. Woodbridge Road were noted as folows: 1.
