Environmental Assessment for the Installation of the Moose Lake Utilidor System, Eielson AFB, Alaska
Abstract
Introduction. Eielson Air Force Base (Eielson AFB) has a resident base population of more than 5,300 active duty and dependent personnel. These residents live in housing that is located mainly on the east side of the base. Providing infrastructure support to this housing is a critical part of the overall base mission. A portion of the utility system that provides heat for the French Creek Subdivision is in critical need of replacement as a result of high groundwater. Description of the Proposed Action. The proposed action will result in the construction of a 2,250-foot-long section of utilidor that would replace an existing direct buried utility line in the Moose Lake area of housing on Eielson AFB. The utilidor would be constructed by excavating to a depth of approximately 1 0 feet, constructing a concrete vault, placing the utility lines in the vault, and then backfilling with nonfrost susceptible material. The proposed action would result in the loss of 0.16 acres of scrub/shrub riparian wetlands. Alternatives to the Proposed Action. There were two alternatives to the proposed action. Alternative 1 would replace the existing damaged/leaking direct buried utility lines with new lines. The new lines would be placed in the same trenches as the previously installed lines. Alternative 2 would install a system identical to that proposed in the proposed action, but rather than construct it in the existing utility line footprint, it would be rerouted and placed in roadbeds to avoid wetlands.
