City of Arcata Oxidation Pond and Klopp Lake Dike Repair and Island Maintenance Project
Document Type
NOE - Notice of Exemption
Document Description
The City's Arcata Marsh and Wildlife Sanctuary contains a tidally influenced lake, Klopp Lake. Klopp Lake is tidally influenced by Humboldt Bay. Prior to its conversion to a brackish lake for wildlife habitat, the pond was used as a leachate basin for an adjoining sanitary landfill that was subsequently closed and capped. There are three islands in the center of the lake that are used as loafing islands by gulls, shore birds, pelicans and water fowl. These islands are being eroded by wave action due to winter storms and prevailing winds. The City is proposing to reinforce these islands and the shore areas with concrete riprap and or 12 to 14 inch boulders and fill behind them with clay to reestablish the islands and diked areas original contours while also halting the erosive action of the water. The outer dike of the oxidation ponds is also being eroded due to winter storms and prevailing winds. The City wishes to reinforce these dikes with concrete riprap and/or 12 to 24" diameter boulders. All the riprap fill will replace the original foot print of dikes or islands and will not fill new areas of Humboldt Bay or Klopp Lake.
