APPENDIX D 



INTERPRETATIONS OP SOILS FOR VARIOUS USES 



Table k, in the main. report, illustrated the type of interpretative 

 information on file for each soil association and major soil. This appendix 

 provides a detailed explanation of each column in Table 4. 



Column 1. Map Symbol. The map symbols are listed in numerical order. 



Colijmn 2. Soil Association and Major Soils. The soil associations and 

 names of the major soils are listed. Soil names are subject to change 

 pending final correlation when the detailed soil survey is completed. 



Column 3- Percent of Association. The percent of the association consisting 

 of each major soil is estimated in this col-umn. 



Column k. Degree and kinds of limitations for Septic Tank Absorption Fields. 

 In making interpretations of soil properties for on-site sewage disposal, 

 the limitations denote problems in location, construction, design, and 

 performance. The design and performance of a waste disposal system connot be 

 based solely on a soil percolation test. In order to make accurate estimates 

 of performance, judgments must be made of such factors as water table, 

 fragipan, bedrock depth, slope, stoniness, rock outcrops, and flooding 

 hazards. Further, the estimates do not take into account the competence of 

 installation, because failures due to errors in judgment and poor workman- 

 ship may occur regardless of soil and site conditions. 



Column 3. Degree and kinds of limitations for Sites for Houses with Base- 

 ments . In evaluating soil properties for homesite locations with basements, 

 the limitations denote problems in excavation, stability of footings, instal- 

 lations, and performance of footing drains. Severity of limitations may be 

 determined by bedrock, stoniness, slumping, lateral seepage of water over 

 fragipan, surface ponding, and slope. 



Column 6. Degree and kinds of limitations for Commercial and Light Industry 

 Sites. In evaluating soil properties for commercial and industrial sites, 

 the limitations denote problems in excavation, installation, performance of 

 footing drains, and stability. Evaluation of the limitations may be deter- 

 mined by slope, water table, bedrock, flooding hazard, lateral seepage of 

 water over fragipan, stoniness, slumping, and surface ponding. 



Col-umn 7. Degree and kinds of limitations for Sanitary Land Fill. The eval- 

 uation of soil properties for trench type sanitary land fill considers the 

 quality of the site. A good sanitary land fill should operate without con- 

 taminating water supplies, reducing land values, or causing health hazards. 

 In addition, it should be usable during all seasons of the year. The soil 

 properties used to evaluate trench type land fill sites are depth to seasonal
