Larry Routten and Erica Crosby -6- November 3, 1993 <br />The Hydrologic Soil Groups used for each of the two vegetation communities were derived as <br />follows: <br />Grassland (Total.Acies ~: 1.23) . <br />Soil Type Acres/% of Grassland Hydrologic Soil Group <br />StC 60/49% B <br />Nd 63/51 °,6 B <br />(All grassland is represented by the B Hydrologic Soil Group) <br />'.Woodland ('total Acres ._: 322j <br />Soil Type Acres/% of Woodland Hydrologic Soil Group <br />TC 44/13% B <br />AbD 113/35°.6 B <br />LkD 105133°,6 C <br />WCR 60/19% D <br />(Based upon an area-weighted average, the C Hydrologic <br />Soil Group is used to represent the Woodland area.) <br />The grassland and woodland communities could justifiably have been represented as follows: <br />Grassland . ....... <br />Cover Type Hydrologic Condition Soil Group <br />Pasture, Grassland Fair B <br />Curve Number = 69 <br />Woodlarid <br />Cover Type Hydrologic Condition Soil Group <br />Pinon-Juniper Fair C <br />Curve Number = 73 <br />These choices would have also resulted in an area-weighted average curve number of 72. The <br />previously used number of 73 was used to represent a pinon-juniper community, in fair <br />condition, with C-group soils. The higher number was used as a rough and conservative <br />
