1000 2000 I I FEET Figure 21. Detail from the Grand Junction 7Yz minute quadrangle showing location of Santa Oara Avenue and the Uimplite Park landslide. . Mitigation Remedial actions taken to stabili2e the landslide area at LampJite Park consisted of the removal of 8 of the 12 af- fected structures, regrading of the ground surlace, and the installation of 10 monitoring wells to observe the perched . water table and provide an early warning system for future instability that might impact Santa Clara Avenue and the utilities beneath it. ADDRESSING UNMET LOCAL NEEDS These three case studies provided the basis for formula- tion of a mitigation assistance strategy by state govern- ment. In each case, local entities had expended con- siderable effort and money in order to mitigate their landslide problems. Yet much still needed to be done, . because technical and financial needs often exceeded the capabi1ities of the impacted communities. Develop- ment of the three cases provided opportunities for the identification of available resources and needs that could not be met at the local level. In many cases, the resource shortfalls identified represented substantial obstacles to reducing the impacts of future landslides on people, property, and essential services. The unmet needs typified the problems that face most local govern- ments impacted by Iandsliding. Thus, once these cases were analyzed, projects could be developed to deal with many high priority local needs. Unmet needs were identified and prioritized following on-site investigation and analysis. Vulnerable areas were evaluated to determine the potential type and magnitude 24 . / .

Health and safety, property loss, economic and social disruption were all considered in each situa- tion. Arrj potential impacts were then aggregated and ranked by priority SO that major potential impacts were clearly identified. A portion of the matrix used for this analytical process is offered as an example in Table 9. Next these high priority potential impacts were listed for ~h major study site and compared against existing response systems available to local governments. Once this comparison was made, residua1 needs were then identified (as sbown in the right hand column of Thble 10) as unmet needs that should be considered by state and federal governments. A portion of this matrix- examining potential "health and safety" impacts for cer- tain specific activities at Glenwood Springs and D~s Junction-is also provided. When all three case studies had been thoroughly analyzed, a wide range of unmet needs were identified, and the most critical were selected to form the basis for state mitigation-assistance projects. Other less urgent unmet needs and potential projects were identified for later consideration by state agenCies. 49
