The Chagrin River Tree Revetment Demonstration project involved the installation of tree revetments to reduce stream bank erosion and reduce downstream transport of woody debris in the Chagrin River watershed. A Tree Revetment Brochure (478 KB) for landowners with questions about restoring eroded streambanks on their property was also produced.

Tree revetment construction includes using cables to anchor large woody debris found in the stream and stream corridor to the stream bank to reduce stream bank erosion and property loss. The logs anchored to the stream bank often act as tree “kickers” which are used to deflect stream flow away from an unstable bank area. The technique reduces stream bank erosion, minimizes the transport of woody debris downstream where it can cause damage to bridges and other structures. Sites were selected based on suitability, access, property owner willingness, potential for success and risk.

These streambank restoration demonstration projects were completed in 2003, and were funded by a 319 grant from the Ohio Environmental Protection Agency with a local match provided Chagrin River Watershed Partners, Inc. and the Ohio Department of Natural Resources. Design and construction was completed by Oxbow River and Stream Restoration. Revetments were installed at three following sites in the Chagrin River watershed.

East Garden Park, City of Eastlake

The East Garden Park is located off Laura Road in Eastlake, Ohio. The stream at this location is Ward Creek. This site is easily viewable and provided easy construction access.

Project Specifics:

  • Total project length is approximately 150 linear feet of stream
  • Project cost $6,800

Installation of tree revetment using:

  • 4-6 large kicker logs
  • 20 linear feet of brush packing under exposed roots of existing tree
  • Approximately 24 - #88 duck bill anchors and 1/4" cable were used to anchor the logs into the stream bank
  • Removed one dump truck load of general debris and three sections of failed 36-inch concrete pipe. The City of Eastlake provided transportation and disposal of material
  • Construct riffle structure using about 10 tons (8 cubic yards) of river rock
  • Seed and mulch disturbed areas
  • Planted Red Osier Dogwoods whips along bank areas

Mathers Property, Russell Township

Mathers Site and is also located along the main stem of the Chagrin River in Russell Township. This is a private property owned by the Mathers Family. This site was limited by wet floodplain conditions and shortage of material. A neighboring property owner offered a large pine tree which was cut and utilized for the project.

Project Specifics:

  • Total project length is approximately 100 linear feet of stream
  • Project cost $6,500

Installation of tree revetment using:

  • 5-6 large kicker logs, include large pine tree offered by neighboring property owner
  • Brush packing along length of project, less brush packing was required at this site due to the use of freshly cut pine tree
  • Approximately 24 - #88 duck bill anchors and 1/4" cable were used to anchor the logs into the stream bank
  • Seed and mulch disturbed areas
  • Planted Red Osier Dogwoods along bank areas

Russel Township Park District, Russell Township

Russell Township Park District Site is located along the main stem of the Chagrin River in Russell Township at the end of Riverside Drive. The property owner at this location is the Russell Township Park District, although construction access through private property. Access was slightly limited through the yard area and wet weather and saturated soils were concerns during construction.

Project Specifics:

  • Total project length is approximately 100 linear feet of stream
  • Project cost $7,000

Installation of tree revetment using:

  • 4 large kicker logs, include utilizing in stream logs
  • Brush packing along length of project (brush was harvested on nearby Russell Township Park District Property)
  • Approximately 24 - #88 duck bill anchors and 1/4" cable were used to anchor the logs into the stream bank
  • Seed and mulch disturbed areas
  • Planted Red Osier Dogwoods along bank areas
