SLIDO is a digital compilation of landslide inventory maps from many City Halls and Jails <br />map sources, and thus the quality and spatial reliability of SLIDO-2 data are highly variable. DOGAMI <br />recommends use of SLIDO as a general planning and preparedness tool. IMS-22 (DOGAMI, 2002) <br />delineates zones that may be prone to landslide hazards, especially rapidly moving landslides. These Critical Communication Hubs <br />A& zones provide information to local governments about property that might require more site-specific <br />evaluation. Mapping of these zones involved GIs modeling, checking and calibrating with limited field <br />evaluations, and comparing with historic landslide inventories. Maps made from these datasets are Public Works and Public Utilities <br />d_ - not a substitute for site-specific investigations by qualified practitioners. Although areas with mapped <br />landslide deposits are likely to be at higher risk than other areas, areas mapped as landslide deposits <br />will not automatically have problems in the future. 8 Public Water Treatment/Storage <br />a Municipal Wastewater Facility <br />E _ 3~ ~g.~, ..ter <br />Electric Substations <br />Wal VL <br />yoF <br />~ z <br />k <br /> <br />it 2 <br />'HAYDEN RAGE RD <br />Ii4VDE• 1' s Ci • ~ C FrK <br />i BRIDGE Rq ~ N G y. a \ <br />
