Chapter 6:Hazard Analysis—Landslides and Rock Falls <br /> 6.5 Mitigation Strategies <br /> 6.5.1 Previous/Current Efforts <br /> The State Department of Transportation tries to address the landslide and rock fall problems <br /> through their maintenance budget. The more chronic problem areas will require additional <br /> CIP (Capital Improvement Project) funding that has not been provided to date; although <br /> landslide events are a concern for our roadways, utilities and structures, and data is available <br /> regarding the frequency and severity of these events. Discussions with State and County <br /> highway maintenance agencies have yielded only anecdotal information regarding landslide <br /> problem areas. Rockfall protection projects have been conducted along stretches of Hawaii <br /> Belt Road. Figure 6-6 illustrates locations where historic landslides have impacted major <br /> roadways in Hawaii County. <br /> Legend <br /> Slope Hazards <br /> _ - Historic Landslides <br /> Other Roads <br /> Major Roads <br /> ORTH KONA <br /> NQRT KONI LIf <br /> }t\ ! <br /> souTH <br /> t HAMAKUA : <br /> SOU HILO <br /> y ORTH KONA ' <br /> SO KONA <br /> NORTH HILOi. � Y <br /> PUNA�J '1 <br /> OUTH KONA <br /> I <br /> Figure 6-6.
