Doc Meister - Bank Erosion

for Kotlik Community Development Plan

Bank Erosion (ID: 2227)

DESCRIPTION:

Name of Infrastructure:
Year Built:
General Description of existing erosion control: Kotlik has been losing river bank at approximately 3 feet per year. Past attempts to utilize concrete riprap failed after a few years. The silt washed away from under and behind the riprap allowing them to become ineffective. The top and bottom photos were areas that the riprap was used. The riverbank continues to erode and is getting perilously close to buildings. The middle photo is across the main community and the white building was originally the first Northern Commercial Co. store. It was moved several times and is again at the edge of the river. The Corp of Engineers performed a feasibility study in June 2003 on Kotlik Riverbank Erosion.

FUTURE NEEDS:

As Reviewed and Approved by the Kotlik Planning Board 2006

Short Term, Mid Term, or Long Term? LT

Local Lead Agency? Kotlik Tribal Council

Future Needs: Riverbank erosion control is needed to protect buildings in Kotlik. Our neighboring community of Emmonak had rock and gravel barged from Nome, Alaska to stabilize their river and it has stopped erosion considerably.

Possible Funding Source(s): Corp of Engineers; Department of Transportation, State of Alaska.
