A healthy beach environment
starts with a good foundation of sediment. The sources of sediment, sometimes
referred to as "feeder bluffs", have historically provided the appropriate type
and amount of sediment to support shellfish, forage fish and other organisms-
which in turn support salmon, and so on. HOWEVER...
Where are the sediment sources in Kitsap County?
Where are the best opportunities to restore or protect these shorelines?
How can we better understand and raise public awareness about the ecological effects of armoring (bulkheads)?
Kitsap County Department of Community Development was the recipient of an EPA Watershed Assistance Grant to:
Identify priority shoreline reaches of existing or potential sediment source value.
Prioritize those reaches by restoration potential, taking landowner willingness into account.
Provide public and private armoring removal demonstration projects to increase public awareness of coastal sediment processes and ecological effects of hard armoring.
This study analyzed existing data to identify reaches of shoreline best suited for restoration and protection of sediment delivery and transport, based on physical attributes and potential for benefit. It then looked at restoration feasibility, using the results of a landowner survey and other attributes such as how far the home is from the shoreline. This resulted in the identified priority reaches and drift cells.

The bulkhead removal and shoreline restoration project at
Anna Smith Park in Dyes Inlet was completed in late August 2012. This project
was identified for its location in a priority sediment source reach. It will
improve natural shoreline conditions by reconnecting sediment sources to the
beach, while improving shoreline access for the public. The bulkhead wall,
rip-rap and old cedar pilings behind the wall were dismantled and removed by
barge. The natural sediments that were trapped behind the bulkhead are now
settling and distributing along the beach. For more information, please
