All f1v.., soils are rdated <br />natural soils and are all loam in nature. These five <br />types are: <br /> <br />,. '\$,",<<1011. Sandy Loam <br />b. Nunn loam <br />c.

The improved properties <br />adjoining the streets arc susceptible to flooding from <br />the f.lajor storm events. These prope.tit,s accommodate <br />single family residences alonf, Berry Circle and multi-far:lily <br />residences, offices and lir,ht commercial along Windermere <br />and Littleton Boulevard. <br /> <br />Other soil types rwy be found in the basin and are generally <br />i~ported fills and otiler mixed soils transported into the <br />area during the construction of sub-divisions. The natm'al <br />soils types were derived from wind and ','ater laid sediments <br />of the Denver and Dawson formations. These soils are fer- <br />tile but susceptible to wind and water erosion.
