The County of Maui Department of Environmental Management proposes to extend the existing shoreline protection at the Wailuku-Kahului Wastewater Reclamation Facility (WKWWRF). In accordance with recommendations for a 1,500 foot revetment from the Army Corps of Engineers to protect the facility, a 450-foot portion of the rock revetment was constructed in 1979.
The proposed project entails completing the revetment with an extension of 1,200 feet of new revetment to the west of the existing revetment. A short section of the extension where it connects to the existing revetment will be aligned seaward of the certified shoreline, then it follows an inland alignment to minimize impacts on the shoreline.
Additional landward extensions will be required at each end of the revetment to prevent flanking. The crest of the new revetment will be between elevations of +1- to + 13 feet Mean Lower Low Water (MLLW) and the toe of the revetment will be set at -3 feet MLLW. The crest elevation of the existing revetment will be raised to match the new revetment crest height to provide additional sea-level rise capacity.
At the base of the revetment will be a layer of geotextile filter fabric, then a layer of bedding stones and two (2) layers of armor stone. Any required fill will be of beach-quality sand, and any additional sand will be used to cover the revetment.
