Building a New Seawall: 4 Decision Factors


Building a new seawall comes with a sea of questions. What goes into deciding if you should build a new one? We wanted to cover a few things in the artcile below. Aging seawalls or severe storms are just a couple of reasons clients have contacted Palmera Construction to guide them in deciding on a new seawall. A seawall is a critical infrastructure that can protect our communities from the impacts of coastal erosion and flooding. However, deciding when to build a new seawall is a complex process that requires careful consideration of various factors. In this blog post, Palmera wants to help you explore the key factors to consider when determining if and when a new seawall is necessary.

1. Coastal Erosion and Flooding Risk

The primary driver behind the decision to build a new seawall on the Treasure Coast is the level of risk posed by coastal erosion and flooding. Communities must conduct a thorough assessment of their vulnerability to these hazards. Data on historical erosion rates, storm surge frequencies, and projected sea level rise should be analyzed to understand future risks accurately. Palmera does a deep dive into helping you as the owner make informed decisions.

2. Cost-Benefit Analysis

Constructing a seawall can be a significant financial investment. Therefore, it is crucial to conduct a cost-benefit analysis to determine if building a seawall is economically viable. The costs include not only the initial construction but also long-term maintenance, permitting, and potential impacts on neighboring areas. Weighing the projected benefits against these costs will help in making an informed decision.

3. Environmental Impact

Seawalls can have both positive and negative impacts on the environment. While they provide coastal protection, they can also alter natural coastal processes, affecting habitats and biodiversity. Before building a seawall, a thorough environmental impact assessment should be conducted to understand potential consequences and explore alternatives that minimize harm to the ecosystem. Palmera Construction is diligent to follow all local, county, and state regulations for building within seagrass and other marine environments.

4. Adaptive Management Strategies

Recognizing the uncertainty associated with weather changes, it is essential to adopt adaptive management strategies. This approach involves continually monitoring and reassessing the seawall’s effectiveness and making necessary adjustments over time. Implementing adaptive management plans ensures that the seawall protects coastal communities effectively amid changing environmental conditions.
