<br /> <br /> <br /> <br /> <br /> INTRODUCTION <br /> <br /> <br /> the natural environment and the rational management of development and future population <br /> growth. <br /> <br /> 1.2 THE PLANNING CHALLENGE <br /> If Puna continues to develop at the present rate within the framework of the extensive <br /> subdivisions, there will be several types of significant, long-term consequences: <br /> <br /> • An increasing number of people and property improvements are being put at risk due <br /> to natural hazards. All of Puna lies within the three most hazardous geological risk <br /> zones: LFI, LF2 and LF3. About 6,400 subdivision lots lie in the highest hazard <br /> zone, LFI, and over 500 of these are exposed to additional risks from subsidence, <br /> tsunami and earthquakes. That 2,038 lots in the lower hazard zone LF2 have been <br /> covered or cut off by lava flows in recent decades underscores the hazardous nature <br /> of much of the district. <br /> Figure 1-2: Geological Risk Zones Relative to Populated Areas and Subdivisions <br /> <br /> <br /> <br /> 1 <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> kn' <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> n c; <br /> <br /> _ H-~/ ~Rl~ 1~-)1f <br /> <br /> <br /> <br /> <br /> <br /> <br /> 1-4 <br />
