of Runway 11/29 begins, however, continued inspection of the repair would be necessary to monitor the condition. Mark Cook then discussed the second option which is to potentially rubblize the entire runway pavement structure then the rubblized asphalt would be reconstituted and then paved over. Mark Cook states that this option would be a ten to twenty year life expectancy on this approach with costs in the million to a million and a half range. Mark Cook added that the first option would be in the five hundred thousand range. Mark Cook continued that the other conversation had with one County Commissioner would be a third -party review of the runway. Mark Cook added that he has tried to be clear about why this action has been taken, while some have stated that the runway is perfectly safe, it is a matter of risk management and the asset has now become a liability. Chairman Jewell asked David Miller with Century West Engineering, the current Airport Consultant for Kittitas County, if he had anything to add to the discussion. David Miller explained the contract with the county for services they provide. Chairman Jewell inquired if Century West Engineering is an expert on runway pavement and if Century West Engineering has evaluated Runway 7/25. David Miller responded that yes, Century West Engineering does consider themselves to be experts in runway pavement and that they have evaluated the runway based on available data including physically walking the runway within the last three months and prepared cost estimates for the rehabilitation options Mark Cook outlined. David Miller then referred to Kurt Addicott with Century West Engineering who is a pavement engineer, if further level of detail is required. David Miller explained the Washington State Department of Transportation WSDOT) Aviation Division's pavement management program and rating criteria with the last rating being done around 2012. David Miller added that the west end of Runway 7/25 received a rating of ten out of one hundred on the rating scale that WSDOT Aviation uses to rate the runway's in the state; other sections rated a bit higher with a thirty to thirty-three rating. David Miller continued that with the rating numbers being so low that putting an overlay on the existing pavement is not possible without rebuilding the base. Discussion was held on the preferred rating for pavement and the reason why Runway 7/25 is not funded by the Federal Aviation Administration (FAA). Further discussion was held. Chairman Jewell then addressed Kurt Addicott with Century West Engineering, inquiring about his experience and his knowledge of pavement. Kurt Addicott stated that he is a Senior Project Manager Engineer with specialty in pavement engineering for airports. Chairman Jewell asked if the runway closure was valid. Kurt Addicott replied that he concurs with Mark Cook's action of closing the runway and that the state of the pavement at the level of PCI rating is in the condition of presenting both property damage and life safety issues. Discussion was held. 2017-08-14 MINUTES
