Event Title

Integrating sea level rise into soft shore protection design: "Sea Level Rise Ready" design

Presentation Abstract

Global sea level will very likely be rising at increasing rates, although the rates are still not known. Recent scientific findings point to higher projections then was understood just a few years ago. It is essential that we integrate these data into the design of soft shore protection and other coastal projects if they are to be successful through their design life. This poster will focus on the considerations and details of the design for one low elevation, residential property located on a north Puget Sound barrier beach, and a second, larger project located at an urban coastal park. The residential case study will feature the many facets required for implementing a “sea level rise ready” project, specifically including: scientific understanding, landowner willingness, working within nearshore habitat and permit constraints, acceptance of non-structural measures for erosion control, integrated design, and oversight during the construction process. The design featured was composed of a broad and increasing elevation backshore berm, placed large wood, and extensive native vegetation, along with a new house set well above the required coastal floodplain elevation. The second case study will feature a park constructed in a moderate wave energy, urbanized setting. The park was constructed on filled/artificial land and was subjected to persistent erosion prior to implementation of the soft shore protection project. Details will be given on the constraints, opportunities, design details, and lessons learned, along with pre-and post-project monitoring results. Together these two projects illustrate a wide range of site conditions with successfully implemented projects.
