Will the Project Affect the Surf or Beach? 
Overview of Beach Morphology, Surf, and Nearshore Nourishment Modeling

A key project element is to reuse native fill excavated during the lagoon restoration and place it in the nearshore areas of the ocean off of Topanga Beach. The goal of this action is to benefit area beaches and avoid unnecessary disposal of clean soils and the associated truck trips offsite. Project consultant Moffatt and Nichol modeled how that material could behave when placed in the ocean so the project could be designed to maximize nourishment, while avoiding sensitive biological resources.


Another key consideration during project development was to determine if the project would affect local surf conditions and the shape of the beach as a key project goal was to protect these onsite resources. Consultants Integral and Moffatt and Nichol modeled how surf and the shape of the beach might change for the different project alternatives, and also considered the duration and type of different environmental conditions (drought, heavy storms).


The following link will take you to the video recording from February 20, 2024 which provides an overview of these studies and their results: YouTube Link

These studies are included in Draft EIR for the Topanga Lagoon Restoration Project and Appendices B - Shoreline Morphology, C - Nearshore Study and H - Surf Quality.
