Overview
Coastal shorelines are inherently dynamic environments, shaped over time by winds, waves, tides and currents, as well as human activities. Increasing sea levels will result in more frequent and extensive storm flooding, and over the long term could mean permanent inundation in some areas. This chapter provides several models for local governments to adopt to preserve the natural protective aspects of shorelines, and to limit the impacts to the built environment.
The chapter is available as a PDF and as a Word document for easy editing and adaption to local needs. Download PDF of Coastal Shoreline Protection Measures Chapter (126 pages).
