This report relates to the flood situation along the Glacier Creek in the vicinity of Girdwood, Alaska, which is located about 35 miles southeasterly from Anchorage. It was prepared at the request of the Greater Anchorage Borough through the State of Alaska, Department of Natural Resources, to aid in the solution of local flood problems and to suggest the best utilization of land subject to overflow. This report is based upon information concerning rainfall, snowfall, runoff, historical and current flood heights and other technical data bearing upon the occurrence and size of potential floods in the Girdwood area. This report covers several significant aspects of the potential flood problems. It first brings together a record of the largest known floods of the past in the Girdwood area. Secondly, it deals with the probability of future floods, such as Intermediate Regional and Standard Project Floods. Intermediate Regional Floods have an average frequency of once in 100 years as determined from an analysis of known floods on Glacier Creek. Standard Project Floods are the largest floods that may reasonably be expected to occur. However, they should be considered in the planning for use of the flood plains.
