Port of San Diego Advances Habitat-Friendly Shoreline Projects to Strengthen Coastal Resilience and Marine Life

Advancing Coastal Protection and Environmental Restoration at San Diego Bay

The Port of San Diego is taking significant strides towards harmonizing coastal protection with environmental restoration. Following the successful pilot program in San Diego Bay, the Board of Port Commissioners recently approved a $2.9 million construction contract aimed at enhancing habitats around Harbor Island Park and the Chula Vista side of the Sweetwater Channel. This proactive approach is critical as the bay’s shoreline has historically relied on conventional infrastructure, such as seawalls, which dominate about 75% of the waterfront. While these structures may effectively prevent erosion, they do little to foster thriving marine ecosystems.

Nature-Based Alternatives

In response to the limitations of traditional methods, the Port has been exploring innovative, nature-based alternatives. A key ally in this initiative is ECOncrete, a company specializing in engineered shoreline systems that promote marine biodiversity. In a previous pilot project in 2021, ECOncrete installed its COASTALOCK units along a 160-foot stretch of Harbor Island, with support from the Port’s Blue Economy Incubator. The results have been promising: after extensive monitoring, Port officials noted that the structure not only held its integrity but also supported over 60 marine species, demonstrating the potential for engineered systems to enhance ecological well-being.

Upcoming Projects

Following the encouraging outcomes, the Port is set to replace sections of the existing rock shoreline at both Harbor Island Park and Sweetwater Channel with habitat-enhancing materials. The Sweetwater Channel site, located near Paradise Marsh, will extend the transformative ecological benefits achieved at Harbor Island into another environmentally sensitive area. These initiatives aim to revitalize the marine ecosystem while maintaining the structural integrity required for coastline protection.

Balancing Preservation and Public Access

Port leaders are underscoring the dual objectives of these projects: environmental enhancement and public accessibility. Board Chair Ann Moore emphasized the necessity of safeguarding the health of the bay while ensuring that residents and visitors can enjoy its beauty and resources. Federal support has played a crucial role, with Representative Scott Peters helping to propel the Harbor Island project forward. His contribution underscores San Diego’s position as a pioneering hub for innovations that align infrastructure with ecological preservation.

Collaborative Funding Efforts

The financial backing for the Harbor Island improvements includes a significant $1 million contribution from the National Oceanic and Atmospheric Administration (NOAA). Meanwhile, the Sweetwater Channel project benefits from a $2.6 million supplemental environmental agreement with the City of San Diego, demonstrating a committed coalition aiming to revitalize shoreline conditions across the bay. This collaborative effort highlights the shared responsibility of various stakeholders to enhance both local ecology and community assets.

Future Prospects

Scheduled to commence in April 2026, the fabrication of specialized shoreline units heralds a new chapter in redefining waterfront infrastructure. Once completed, these projects will mark a significant advancement in integrating environmental restoration with durable coastal protection. By employing habitat-friendly designs, the Port is not only reinforcing coastal resilience but also supporting biodiversity and contributing to the growth of the region’s Blue Economy. This innovative approach serves as a model for other coastal communities seeking to balance development with ecological health—showing that infrastructure and sustainable practices can indeed coexist harmoniously.
