70 Hurricane Ike - Some Lessons Learned Our priority/key customer list (hospitals, public health & safety facilities, including water pumping stations, etc.) needs continuous updating Next time we will operate with more and smaller staging sites We had IT issues at staging sites which inhibited our ability to quickly report progress. We have extensively improved our remote site telecom and IT capability. We will increase Damage Assessment effort recognizing that this activity is critical to our ability to report restoration times We have developed processes and procedures and technology to enable us to accurately report restoration times on the internet by zipcode. 69
