Most of <br />the alluvial fans are in undeveloped areas of the county. <br />There is historical evidence of problems with landslides at some canyon mouths.

The county has no <br />standard procedure to identify and classify alluvial fans. <br /> <br />Attachment 2 - Appendix A <br /> <br />1 <br /> <br />
