The purpose of this manual is to present information on project operation and maintenance OM for compliance with Federal regulations. Shoreline erosion control features at Lincoln Park, Seattle, Washington, were constructed in 1988 under the River and Harbor Act of 1962. Lincoln Park is a heavily wooded park consisting of flat uplands, steep bluffs, and gently sloping beaches. Park facilities include a 1-mile-long saltwater beach. A concrete and cobblestone seawall extends the entire length of the shoreline. The project is designed to provide long-term shoreline-erosion protection at Lincoln Park in order to prevent damage to publicly owned property. Major OM components for the revetment, periodic beach nourishment, and project monitoring are discussed. The primary objective of the revetment is to absorb wave energy and reduce wave overtopping and wave erosion. The primary objective of nourishment is to maintain the nearshore beach profile seaward to the limits of active wave influence on the bottom materials. An annual field inspection will be made to ascertain armor and toe rock displacement, overtopping problems, and damaged or vulnerable portions of the revetment and to observe and note the degree of erosionaccretion of the beach nourishment.
