Sources: <br />Statewide Landslide Information Database, version 2 (SLIDO-2), from Oregon Dept, of Geology and <br />Mineral Industries (DOGAMI). SLIDO is a digital compilation of landslide inventory maps from many ffi 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 />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 />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 pronlems in the future e Public Water Treatment/Storage <br />`s ~ Municipal Wastewater Facility <br />8 Electric Substations <br />Zip, <br />a <br />s <br />. 4 <br />O <br />7 <br />[ ~NAVOcN RIDGE RD C r 4 <br />(r FL4VDE eRIDG 1' C ~"1 3 R sr f <br />diSSJ~ ~a MAIN ST <br />t _J <br />y <br />x <br />Y a s. v. <br />C <br />yf. c~ <br />g h~yr <br />7 ~ Se <br />
