Elevations are relative assumed elevation of 100.0 based <br />at a single spike in the south face of a po. pole along the east property <br />boundary (see enclosed sketch). <br />'.-his :sport includes: <br />1. Soil boring logs <br />2. Percolation test results <br />3. Copy of preliminary percolation test results and soil boring loge <br />taken at site in May. 1980 <br />4. Discussion and recomm.ndntions. <br />The numbering system for the lots has changed since initial testing was performed <br />in 19�30. For consistency between rerco.ation test reports, the initial numbering <br />system for the testholes is used in this report. <br />The so{1 boring lnus show silt loam to clay loam surface soils overlie variably <br />textured clav subsurface horizons. Significant soil mottling begins at 0.5 to <br />2.5 feet depth at most of the boreholes. Soil mottles (spits of contrasting <br />color) are accepted indicators of periodic. Katuratlon in soils.
