NOW,THEREFORE,BE IT RESOLVED BY THE CITY COUNCIL OF THE CITY OF SEWARD, ALASKA that: Section 1. The City of Seward requests the State of Alaska's immediate assistance to begin mitigation efforts to protect the City of Seward and Lowell Point community. Section 2.

DGGS examined all of the reports and provided a combined report with recommendations concerning Bear Mountain and probable future devastation to the Lowell Point and Seward communities. The report identifies four areas of failure with the possibility of creating a devastating local tsunami. It is imperative that Bear Mountain be further investigated with ground-based studies, instrumented as soon as possible, and closely monitored for potential movement, as soon as possible. Knowing the magnitude of the report and the City's lack of capacity to conduct the required studies and the finances to mitigate the threats; a meeting was held with the involved State of Alaska departments. The departments agreed that the matter must be elevated to the State of Alaska. On June 16, 2022, the State Emergency Operations Center contacted the City Manager about the need to begin the State process and the immediate submission of a 213 Resource Request (RR). The 213 RR was submitted, along with information about the upcoming city council resolution.
