With over six miles of coastline, the beach is a way of life in the City of Encinitas. The Coastal Zone Program aims to responsibly manage these coastal resources to benefit our community, as well as local habitats. This branch deals with concerns regarding the environment, commerce, recreation, hazardous weather impacts, aesthetics, quality of life, water, erosion, and more. The dynamic and evolving program incorporates the latest research, grants, projects, and partnerships allowing adaptation to our changing conditions to maintain our coastline as a thriving ecological and recreational resource for generations to come.
Preparing for Sea Level Rise
Rising sea levels due to climate change pose a threat to coastal communities worldwide. The City aims to protect the community’s coastal infrastructure, recreational opportunities, and ecosystems by building coastal resilience through the following projects.
Encinitas-Solana Beach Coastal Storm Damage Reduction (San Diego County) Project
The U.S. Army Corps of Engineers (Army Corps) announced in February 2020 that funding had been approved to allow the cities of Encinitas and Solana Beach to begin pre-construction monitoring and design engineering for a large sand nourishment project aimed at enhancing coastal resiliency against storm damage and sea level rise. The San Diego County coastline is in a constant state of erosion, as natural sand processes have been interrupted by coastal and upland development, flood control, dams, harbors, and hard infrastructure along the shoreline, like seawalls, groins, rip-rap, and levees. This erosion is exacerbated by storm surge at high tide with additional effects from strong waves. In Encinitas, the impacts of this erosion are felt by narrowing beaches and wave encroachment on our bluffs, which threaten public and private infrastructure and beach safety. The primary goal of the Coastal Storm Damage Reduction Project (Project) is to add sand to our eroding shoreline, with the aim of attenuating waves that further erode the coastal bluffs and providing more useable beach sand for safer beach conditions.
In Encinitas, the Project involves the construction of a 50-foot-wide beach fill along a 7,800 foot-long stretch of shoreline (from Beacons to Boneyards) using 340,000 cubic yards of compatible sand, with renourishment every 5 years on average over a 50-year period. Though the Project had been authorized by Congress since 2016, critical federal funding had not been allocated until early 2020. U.S. Rep. Mike Levin and Senator Dianne Feinstein along with the Encinitas and Solana Beach City Councils, concerned residents and city staff led a vigorous campaign to secure the funds from the Army Corps and the U.S. Office of Management and Budget.
Since April 2020, the cities of Encinitas and Solana Beach have been working with the Army Corps (Los Angeles District) in the development of the Project Management Plan and the Design Agreement, which solidify our participation in the Project as the local sponsor. Additionally, the Project team has been developing the pre-construction monitoring plans. Initial monitoring for the Project will begin in fall 2021 and continue until fall 2022, and will entail studying:
· beach profiles and sand volumes
· surfing and wave characteristics where sand placement will occur
· physical conditions of the sand in the offshore borrow sites
· biological conditions of the nearshore reef and intertidal zone
These studies will determine a baseline that will be utilized by the cities and resource agencies to track any physical or biological changes seen over the life of the Project. Project construction is slated to begin in 2023.
Sand Compatibility and Opportunistic Use Program (SCOUP)
SCOUP is part of a regional sediment management plan intended to streamline beach nourishment projects. The standardized permitting process facilitates the use of available sand from construction sites and other opportunistic sources. The program includes stringent environmental regulations to ensure that the sand sources are compatible with receiver sites. The timing and location of sand placement are also strictly controlled to reduce any negative impacts on coastal habitats and recreation. For more information on SCOUP visit SANDAG's Website.
The City of Encinitas has used beach nourishment for many years as a method of building coastal resilience. As of summer 2021, there are three potential SCOUP project locations at local beaches, the largest of which involves removing the remaining sand associated with the San Elijo Lagoon Restoration Project and placing the sand at Moonlight Beach.
Cardiff Beach Living Shoreline Project – Dune Restoration Project
2020 winner of ASBPA Best Restored Beach Award!
The Cardiff State Beach Living Shoreline is an innovative “green infrastructure” project featuring 2,900 ft of reconstructed dunes. Located on the seaward side of Highway 101 on Cardiff State Beach, the dune system protects a vulnerable segment of the roadway in addition to restoring natural habitat.
The city chose to replace the existing cobble revetment with dunes which naturally occurred along the Encinitas coastline before urbanization. The dunes provide numerous ecological and human benefits including habitat for native species and protection from sea-level rise and storm surge flooding. The newly renovated shoreline can now support flowering native plants and other coastal dune species once again.
The State Coastal Conservancy, the San Diego Association of Governments, the United States Fish and Wildlife Service, and the Ocean Protection Council have provided the funds to provide an adaptation measure to reduce the potential impacts due to sea-level rise while also improving the native dune habitat. For more information on this project, please see this recent article published by the USFWS Pacific Southwest Region.
The California Coastal Analysis and Mapping Project (CCAMP), completed in 2018 by the Federal Emergency Management Agency (FEMA), was an extensive, fifteen-year undertaking involving detailed coastal engineering analysis and mapping of the Pacific Coast of California. The results were used to create interactive and updated maps of the coastal flood risk and wave hazards for the California coastline. Key coastal processes such as dune erosion, wave setup, wave run-up, overtopping, overland wave propagation and evaluation of coastal structures were accounted for in determining new Base Flood Elevations (BFE).
Coastal Ecology and Conservation
Swami's State Marine Conservation Area
Marine Protected Areas are the oceanic equivalent of State and National Parks. They are scientifically proven to promote the restoration of ecosystems and biodiversity which help increase the resilience of oceans to pollution and climate change. The City of Encinitas is home to Swami’s State Marine Conservation Area. This protected area sustains multiple habitats which include kelp forests, surf grass beds, and rock reefs which support a variety of fish and invertebrate species. During low tide, visitors can also observe tide pool dwellers such as anemones, brittle stars, sea hares, and octopi. To ensure the continued success of this ecosystem, take of all living marine resources is strictly prohibited EXCEPT the recreational take of finfish by hook-and-line from shore only and pelagic finfish including Pacific bonito and white seabass by spearfishing (CA Department of Parks and Recreation).
Beacon's Beach Restoration
Beacon's Beach Restoration is a current project that exemplifies the balance of habitat protection with recreational opportunities. The primary objective of the project is to stabilize the bluff using native vegetation to protect the access trail at this popular beach destination. The restoration of native plant species will have the twofold benefit of reducing bluff top erosion and increasing habitat area. The restoration plan includes a pilot project using washed up kelp to enhance natural dune formation. Long term monitoring plans include citizen science opportunities to increase engagement and stewardship in the community. For more details on this project, please see the Beacon’s Beach Coastal Bluff Landscape Restoration Plan.
Grunion Run Anyone?
The California Grunion is a thin silvery fish that is part of the New World Silversides family. They are known for their unique spawning process which occurs each year from March to September. During spawning events, known as Grunion Runs, masses of fish come ashore to lay their eggs in the wet sand. They are the only fish species to lay eggs completely out of the water. This unique ritual can create a magical spectacle with thousands of fish coming ashore at once. Runs are dependent on tide conditions and can be predicted years in advance. Although the exact population of grunion is unknown, a downward trend has been detected in recent years due to beach erosion, development, and pollution. Researches rely on observations from the community to help assess the health of the species.
Get involved with citizen science, help a locally threatened species, and have fun by participating in a Grunion Run! See below for a comprehensive table of Grunion Run dates. The Grunion may show up at any sandy beach but Cardiff State Beach and Ponto State Beach have historically had the best turn out.
