A general soil map of Larimer County used in conjunction with <br /> <br /> <br />table 3 Jf the CSU publication lists ranges of infiltration permeabili- <br /> <br /> <br />ties for each soil series. Table 10 contains the soil associations <br /> <br /> <br />that were taken from the general soil map, the range of infiltration <br /> <br />permeabilities for each soil series, and the infiltration rate that was <br /> <br /> <br />used in the SWMM model. <br /> <br />28 <br /> <br />. <br />
