Alluvium is a rock formation that contains an aquifer good for domestic and farm use.  It is also excavated for topsoil.  Development on alluvium is limited only by the hazard of flooding.  There are buildings and structures above the 100-year floodplain.  Recreation facilities such as trails should be above the 100-year flood incident or designed to withstand periodic inundation.
