Engineering Solutions for Coastal Erosion: Mitigating the Effects on Buildings and Infrastructure

Coastal erosion is a natural process that can have significant impacts on buildings and infrastructure located near shorelines. As a leading structural engineering firm, Mike Stewart P.E. is at the forefront of developing and implementing innovative solutions to mitigate these effects. Our work in coastal areas has not only protected valuable property but also preserved the natural beauty and ecological balance of these environments. In this blog post, we'll explore some of the engineering solutions we've employed to combat coastal erosion and safeguard structures against its relentless force.

Understanding Coastal Erosion

Coastal erosion occurs when wind, waves, and currents remove sand and soil from the shoreline, leading to loss of land and potentially endangering buildings and infrastructure. The impact can be exacerbated by human activities and climate change, making it a growing concern for coastal communities.

Structural Solutions to Combat Erosion

At Mike Stewart P.E., we employ a variety of structural solutions tailored to the specific needs of each site. Here are some innovative approaches we've taken:

1. Seawalls and Revetments

Seawalls and revetments act as barriers to absorb and deflect the energy of incoming waves. We design these structures to blend with the natural landscape, using materials that are durable and environmentally friendly. Our focus is on creating barriers that provide protection while minimizing the impact on natural coastal processes.

2. Groynes

Groynes are structures built perpendicular to the shoreline, extending into the sea. They trap sand moving along the coast, preventing it from being washed away and thus combating erosion. We've designed groynes that not only serve their protective function but also enhance local biodiversity and recreational opportunities.

3. Beach Nourishment

Beach nourishment involves adding sand or sediment to beaches to counteract erosion. This method preserves the natural appearance of the coastline and supports habitat for wildlife. Our firm has managed several beach nourishment projects, carefully selecting materials that match the natural composition of the beach and monitoring the impact on coastal ecosystems.

4. Living Shorelines

Living shorelines are a softer approach to erosion control, using natural elements like plants, sand, and rock to stabilize the shoreline. These solutions promote the growth of coastal habitats while protecting against erosion. Our designs for living shorelines prioritize ecological sustainability and adaptability to rising sea levels.

The Role of Monitoring and Maintenance

Effective coastal erosion management requires ongoing monitoring and maintenance. We incorporate advanced monitoring technologies into our projects, allowing us to observe changes in shoreline patterns and adjust our strategies as needed. Regular maintenance ensures the longevity and effectiveness of structural solutions, protecting investments and the environment alike.


Coastal erosion presents a significant challenge, but with innovative engineering solutions, it is possible to mitigate its effects and protect valuable coastal assets. At Mike Stewart P.E., we're committed to developing strategies that blend structural integrity with environmental stewardship, ensuring that our coastlines remain vibrant and secure for generations to come. Whether through hard engineering structures or softer, nature-based solutions, our goal is to provide effective, sustainable protection against coastal erosion.
