Maryland’s shorelines face constant erosion from natural forces like wave action and human activities, including boat wakes and stormwater runoff. This erosion damages ecosystems, reduces property values, and threatens infrastructure. To combat this, Maryland promotes Best Management Practices (BMPs) that balance protecting shorelines with maintaining natural habitats. Key solutions include:
- Living Shorelines: Use native plants, marsh grasses, and oyster reefs to absorb wave energy and stabilize sediment. These are cost-effective ($22/linear foot) and support marine life.
- Structural Solutions: Revetments and bulkheads provide stability in high-energy areas but require regular maintenance and can harm nearby ecosystems.
- Plant-Based Stabilization: Native vegetation like smooth cordgrass and salt meadow hay anchors soil and reduces erosion naturally.
- Stormwater Management: Techniques like French drains and grading redirect runoff, reducing erosion and sediment flow.
For success, property owners must plan carefully, comply with Maryland’s strict permitting rules, and monitor projects regularly. Combining natural and structural methods ensures long-term shoreline protection while preserving the Chesapeake Bay‘s health.

Maryland Erosion Control Laws and Regulations
If you’re planning a shoreline erosion project in Maryland, you’ll need to work through a maze of state and local regulations. These rules are designed to protect tidal waters while ensuring that all projects meet environmental and permitting standards. Understanding these requirements is essential before you get started.
Permit Requirements for Shoreline Projects
Any project that impacts tidal waters or extends below the mean high water mark requires a marine construction permit from the Maryland Department of the Environment (MDE). For instance, Calvert County simplifies the process for property owners by offering a specific form for "Shoreline Erosion Control Measures – Activity" in its permit section.
To make the approval process smoother, consider hiring experienced professionals. They can help prepare the necessary documentation, such as engineering plans and environmental assessments, ensuring your project complies with all requirements.
Best Management Practices for Shoreline Erosion Control
Maryland’s coastal areas demand erosion control strategies that not only protect property but also work in harmony with the environment. By blending natural methods with thoughtful engineering, property owners can create shorelines that are both durable and supportive of marine ecosystems.
Living Shorelines
Living shorelines are a nature-based solution for managing erosion in Maryland’s tidal regions. These approaches use native marsh grasses, oyster reefs, and other materials to create a barrier that works with natural coastal processes. For example, planting native marsh grasses behind stone sills or oyster reefs absorbs wave energy while the plants’ roots stabilize sediment.
Their effectiveness becomes especially evident during storms. Studies reveal that living shorelines outperform hard structures during hurricanes and other extreme weather events [1][2]. Beyond protection, they offer ecological benefits, supporting over 25% more biodiversity and 35–40% more marine life compared to hardened shorelines like seawalls and bulkheads [3]. These systems also contribute to cleaner water, store carbon in wetlands, and provide habitats for fish and crustaceans [1].
Cost is another factor in their favor. Surveys from Florida show that living shorelines are 8.5 times cheaper to install and 2.7 times cheaper to maintain than hardened alternatives. In Maryland, installation costs average about $22 per linear foot, with annual maintenance running around $138 [4].
In cases where natural solutions alone aren’t enough, structural measures can provide additional reinforcement.
Structural Solutions
For areas facing extreme wave energy, structural solutions like revetments, bulkheads, and offshore breakwaters offer extra protection. Revetments, made from rock or concrete, shield the shoreline while still allowing some water movement. Bulkheads act as vertical barriers separating land and water, and offshore breakwaters reduce wave energy by acting as a buffer before waves hit the shore.
However, these structures come with challenges. They degrade over time due to constant wave action and storms, requiring regular upkeep [2]. Installation costs average $184 per linear foot, with annual maintenance around $370 [4]. While they may seem like a sturdy option, the long-term environmental and financial costs can add up. Hardened shorelines often amplify wave energy, fragment habitats, and reduce local biodiversity.
Plant-Based Stabilization Methods
Native vegetation plays a key role in stabilizing shorelines. The right plants can anchor soil with their root systems, reducing erosion naturally. For areas prone to flooding, Spartina alterniflora (smooth cordgrass) absorbs wave energy effectively, while Spartina patens (salt meadow hay) thrives in slightly elevated zones. In less salty areas, plants like switchgrass (Panicum virgatum) and saltgrass (Distichlis spicata) are excellent choices. Shrubs and trees like Baccharis halimifolia and Myrica cerifera (southern bayberry) can also provide structural support and create habitats for wildlife.
Planting in the fall or early spring gives vegetation time to establish strong roots. Although it may take two to three growing seasons for plants to fully mature, their stabilizing effects improve over time. To maximize results, plant-based methods should be paired with strategies to manage water flow.
Stormwater and Drainage Management
Unmanaged runoff can accelerate shoreline erosion by channeling water and sediment into vulnerable areas. Proper stormwater and drainage management can redirect water flow, reducing erosion and protecting water quality.
French drains, for example, use perforated pipes surrounded by gravel to intercept groundwater before it saturates shoreline soils. Grading and leveling the land can help direct water to infiltration zones, while dry riverbeds with a mix of stone sizes can slow water during storms, allowing sediment to settle before reaching the shoreline.

How to Implement Shoreline Erosion Control Projects
Building on Maryland’s erosion control standards, successfully executing a shoreline erosion control project requires careful planning, adherence to regulations, and ongoing maintenance. By following a structured approach, property owners can avoid costly mistakes and develop long-lasting solutions that protect both their investment and Maryland’s coastal areas.
Project Planning Checklist
Start with a thorough site assessment. Begin by documenting signs of erosion – take photos, record measurements, and note any visible damage. Maryland’s regulations demand clear evidence to justify erosion control measures [6].
Next, assess whether natural tidal wetlands on your property are already doing their job. If these wetlands are effectively controlling erosion, the Maryland Department of Natural Resources may not approve additional interventions [6]. This step ensures that any proposed measures are truly necessary.
During the site assessment, pay attention to factors like your property’s exposure to waves, soil type, and proximity to sensitive areas, such as oyster bars or historical sites. Maryland encourages nonstructural stabilization methods, particularly in tidal wetlands [6]. Before moving forward with active measures, consider alternatives like "no action" or relocating vulnerable structures.
Research permits early on. Confirm whether structural solutions are allowed for your location and check with local authorities about specific requirements. Structural measures are only permitted in areas designated as suitable by the Department of Natural Resources or when a waiver is granted after proving that nonstructural options aren’t feasible [6].
For projects that involve work in wet areas, plan for dewatering solutions, such as inflatable cofferdams, to ensure a dry and safe workspace during construction [5]. Proper preparation can help you avoid delays and ensure smooth progress.
A well-thought-out plan reduces the risk of errors. Next, let’s look at common mistakes that can derail a project.
Common Mistakes to Avoid
Shoreline erosion projects often fail due to avoidable errors during both planning and execution. Here are some key pitfalls to steer clear of:
- Jumping to structural fixes too soon. Bulkheads and retaining walls, though widely used in the past, can actually worsen erosion over time and harm the environment [5]. Maryland regulations require proof that nonstructural methods won’t work before approving structural solutions.
- Neglecting permit research. Skipping this step can lead to delays, fines, or even a complete project redesign. The Department of Natural Resources may deny projects that negatively impact neighboring properties, navigation, wildlife, historic sites, or oyster habitats [6]. Early consultations with regulatory agencies can help you avoid these roadblocks.
- Poor site preparation. Ignoring drainage issues or choosing plants that aren’t suited to local salinity and wave conditions can doom your project from the start. Planting at the wrong time of year – outside of fall or early spring – can also reduce the chances of success.
- Underestimating maintenance needs. Living shorelines require consistent monitoring, especially during their early stages. Without regular inspections, especially after major storms, erosion control systems can deteriorate, leading to expensive repairs or even a complete rebuild.
By avoiding these common mistakes, you’ll be better positioned to create an erosion control system that stands the test of time. The final step is establishing a proactive monitoring routine.
Monitoring and Maintenance
Ongoing monitoring is essential to ensure your shoreline project continues to protect your property effectively. Set up a monitoring schedule within the first month after completing the project. During the first year, inspect vegetation monthly, then shift to seasonal checks. Pay close attention to storm impacts and address any necessary repairs promptly.
Post-storm inspections are especially important. After significant weather events, document damage with photos, measure new erosion, and observe changes in sediment patterns. This information can be invaluable for insurance claims and planning repairs.
Fall inspections are a good time to identify necessary repairs and clear drainage systems. Maintenance tasks often include replanting areas where vegetation hasn’t taken hold, removing invasive species, and cleaning out drainage structures. Keep detailed records of all monitoring visits, maintenance activities, and site changes. These records are not only helpful for insurance and regulatory compliance but also for planning future improvements.

Case Studies and Local Expertise
Examples from Maryland’s coastal regions highlight the effectiveness of erosion control strategies. These success stories show how protecting shorelines can go hand-in-hand with preserving natural habitats, emphasizing the importance of working with professionals who understand Maryland’s unique environmental and regulatory landscape.
Examples of Successful BMP Implementation
The Severn River Association (SRA) collaborated with BayLand Consultants & Designers Inc. to tackle erosion issues in the Severn River watershed. Their approach demonstrated how living shorelines – a method using natural stabilization techniques – can effectively reduce erosion while improving habitat quality. This project replaced deteriorating bulkheads with native plantings and sediment control measures, creating a more sustainable solution.
One standout advantage of this method is cost. Living shorelines typically range from $150 to $500 per foot, significantly less than bulkheads or revetments, which can cost anywhere from $500 to $1,200 per foot[7]. Not only are living shorelines often more affordable upfront, but they also require less maintenance over time and contribute to healthier ecosystems.
Community involvement played a key role in the Severn River projects. BayLand Consultants worked closely with property owners to address concerns about aesthetics and functionality. The result? Natural shorelines that not only protect against erosion but also enhance property value and waterfront enjoyment.
Stormwater management was another critical element. These projects proved that no one-size-fits-all solution exists for erosion control. Factors like wave activity, soil type, and vegetation must all be considered to determine the best course of action.
These case studies illustrate the tangible benefits of well-planned erosion control measures and highlight the importance of expert guidance to implement effective solutions.
