The Talkeetna Dike provides essential erosion protection to the Talkeetna residents. Over time, riprap armoring along a portion of the dike has failed and left the remaining embankment unprotected and subject to further erosion.
HDL developed the design and permits needed to secure Federal Emergency Management Agency funding for repair of this critical infrastructure. The design to reconstruct 500-feet of the existing 1,000-foot dike will with stand a 100-year flood event and prevent further scour at the toe of the dike.
