To: Mayor George N. Ahmaogak, Sr. Through: CAO Dennis Packer John Ames, Director of Administration and Finance John Miller, Deputy Director Administration and Finance Joe Stankiewicz, Risk Manager From: Rob Elkins, Assistant Risk Manager Date: August 6, 2003 Subject: Storm Report SUMMARY OF INCIDENT: The days of July 28 and 29 saw a coastal storm embrace the North Slope Borough. Caused by the formation of a low pressure system over Russia, the storm then moved east, and passed approximately 250 miles north of Barrow. As a result of the storm, waves approaching 12 to 15 feet were driven by winds ranging from 30 to 48 mph. The North Slope Borough Department of Municipal Services began preemptive measures to reduce the storms impact on the coastline on the morning of July 28th. Existing sand and gravel burms along the Barrow coastline were built up, while new ones were constructed in previously unprotected areas. By 2:00 pm on July 29th, storm surges began eroding a portion of the Stevenson road just south of the Barrow Landfill. DMS personnel closed the roadway, utilizing Cakeeater Road as an alternate route. Erosion from the high seas also caused closure of portions of Egasak Street. Substantial erosion was reported in Wainwright, where a bluff housing several ice cellars was threatened. Kaktovik saw waves sufficient to force temporary closure to the airport runway, also forcing the runway lighting system to be turned off to avoid further damage. The storm subsided by 5:00 pm on July 29th, whereupon DMS personnel began reparations to areas damaged by the storm. ATTRIBUTABLE COSTS: Location Barrow Barrow Item Overtime wages (72 hours) Gravel (42 loads) Cost $10,752.00 Barrow and Wainwright 400 Large Sand Bags $57,180.00 Costs attributable to efforts to remediate damage in Wainwright are unavailable at this time. With the stated intentions of DMS to backfill eroded areas, along with the filling of super-sacks with sand to provide additional protection to the area, it appears total cost of manpower and materials will easily exceed $10,000. RECOMMENDATIONS: With ongoing climate change, and predictions of disappearing sea ice in the recent future, the likelihood of severe damage from future coastal storms is high. Recent events illustrate the vulnerability of Stevenson Street to damage from coastal storm surges. Serious thought must be put into how the North Slope Borough can best protect both public and private properties bordering our coastline. Temporary measures, such as sandbags may have some short-term value, but their utilization to provide long-term remediation is questionable. Additional thought should be given to the development of an alternative roadway connecting NARL and Barrow. The annual challenge of damage to Stevenson Street and Egasak Street is likely to worsen in future years, eventually causing risk of inability of emergency service provision to NARL for substantial periods of time. Development of an eastern access to NARL would mitigate this risk. More severe measures, such as the construction of a seawall, or relocation of structures and infrastructure threatened by future coastal erosion should be carefully studied based upon a cost/benefit ratio. The protection of the current landfill from being breached by erosion, and the potential for pollution of our coastal environments must also be weighed carefully. The annual challenges of flood damage to the runway in Kaktovik also illustrate a need to either protect the current runway with a seawall, or examine the need to completely relocate the facility to a more protected area. Again, this decision needs to be studied closely, with determination being made based upon a cost/benefit ration.
