airport) and the Stockton fire station as reported in NOAA (National Oceanic and Atmospheric Administration)records. The two Stockton stations are located approximately 17 miles south of Buckeye Ranch. For all statistics except average annual rainfall the Stockton records were used. Although the Lodi station is closer to the Ranch those records could not be used because data for all variables besides rainfall are missing from Lodi reports. The average annual temperature is 650 Fahrenheit. Winters are cool and the average January temperature is 450 F with a range between 32.3 -56.50 F. Summers are hot and the average July temperature is 750 F with ranges between 54 -970 F. The maximum temperature recorded was 1140 F in July of 1972 and the minimum (before the December 1990 cold snap) was 190 F in 1963. The frost free growing season lasts about 240 days. Precipitation averages about 14" annually in the Stockton area and the Lodi station receives about 16" annually. December and January are usually the wettest months. Little or no rainfall falls between June and September. Fog, locally referred to as tule fog, is common in the winter and the Stockton area records an average of 43 days of heavy fog per year. The topography of the area modifies the regional climate and the numerous drainages create patterns of cold air flow, which may result in localized frost pockets. The forest with its dense, evergreen canopy insulates the ground beneath it and protects the understory vegetation from frost. 2.3 Geology and Soils Preliminary information on Buckeye Ranch soils was collected from the U.S. Soil Conservation Service by Pam Muick in 1989 and is included in the Buckeye Ranch Planned District Description. In addition Lowry &Associates drilled a number of borings on the property in 1990. The results of the borings are also included in the Planned District Buckeye Ranch Resource Plan (November, 1993) 23
