The criteria for determining the hydrologic soil group for individual soil components is <br /> found in the National Engineering Handbook, Chapter 7 issued May 2007(http://directives.sc.egov.usda.gov/ <br /> Open NonWebContent.aspx?content=17757.wba). Three values are provided to identify the expected Low(L), <br /> Representative Value (R), and High (H). <br /> Engineering Properties-Logan County,Colorado <br /> Map unit symbol and Pct.of Hydrolo Depth USDA texture Classification Pct Fragments Percentage passing sieve number— Liquid Plasticit <br /> soil name map gic limit y index <br /> unit group Unified AASHTO >10 3-10 4 10 40 200 <br /> Inches inches <br /> In L-R-H L-R-H L-R-H L-R-H L-R-H L-R-H L-R-H L-R-H <br /> 3—Alda loam <br /> Aida 85 B I 0-10 Loam CL-ML, A-4 0-0-0 0-0-0 95-98-1 90-95-1 85-90- 60-68- 20-23 <br /> ML 00 00 95 75 -25 <br /> 10-34 Stratified loamy sand CL-ML, A-2,A-4 0-0-0 0-0-0 95-98-1 'I 90-95-1 50-73- 15-45- 20-23 <br /> i <br /> to loam ML,SC- 00 00 95 75 -25 <br /> SM,SM <br /> W 34-60 Very gravelly sand GP,GP- A-1 0-5-10 0-5-10 35-45- 30-40- 20-28- iNP <br /> t0 GM,SP, 55 50 35 <br /> —� SP-SM <br /> 28—Fluvaquentic -- - — - --- -- -- - <br /> Haplaquolls <br /> Fluvaquentic 90 D 10-1 1 Variable — — — — — — — — <br /> ha <br /> plauolls <br /> q 12-60 Stratified gravelly GC-GM, A-2,A 4 0-3-5 0-5-10 60-73- 55-68- 50-60- 20-35- 15-20 NP-5 <br /> l <br /> sand to loam GM, 85 80 I 70 50 -25 -10 <br /> SC-SM, <br /> SM <br /> 29—Fluvaquents <br /> Fluvaquents 90 D 0-10 Variable CL,ML, A-2,A-4, 0-0-0 <br /> -0-0 0-5-10 90-93- 85-90- 55-60- 20-40- 15-23 NP-8 <br /> Sc,SM A-6 95 95 65 60 -30 -15 <br /> 10-60 Very gravelly sand, GP,GP- A-1 0-0-0 10-20- 40-60- 30-50- 10-18- 0-5-10 — NP <br /> gravelly sand GM,SP, 30 80 70 25 <br /> SP-SM <br />
