NACD August2020 U&C Webinar – North Cove Coastal Project

The Pacific Conservation District in Washington will highlight the North Cove Coastal Project in the next NACD Urban and Community Conservation webinar, which is scheduled at 12:00noon-1:00pm Eastern time on August 20, 2020.

Shoreline erosion has been a disastrous problem for the North Cove community for over 100 years. Two-by-six square miles of land has been devoured by the ocean. If nothing was done, erosion would have continued until it engulfed State Route 105. This would have resulted in a loss of hundreds of acres of homes and the valuable cranberry farming ground that stretches from Willapa Bay to Grays Harbor. Historic dredging and riprap armoring are believed to have contributed to changing drift currents and sediment transport.

This project represents a new approach to addressing erosion at the site and emulates natural process along the upper Washington coast and Oregon coast. Work consisted of placing cobble against the existing erosion scarp to create a porous, dynamic revetment. The revetment dissipates wave and tidal energy by allowing individual rocks to move and absorb the wave energy, rather than deflecting energy like a typical revetment. The dynamic revetment helped protect existing vegetation and beach sands from scour/erosion during storm events. Large woody debris was installed to help reduce lateral erosion.

These popular webinars, held on the third Thursday of each month, are sponsored by The Scotts Miracle-Gro Foundation in partnership with the NACD Urban and Community Resource Policy Group. There is no cost to participate, but space is limited. Registration will be accepted on a first-come, first-serve basis.
