Erosion control and stormwater BMPs (Best Management Practices) are two critical strategies for protecting Maryland properties from water damage and soil erosion. While they are often confused, they serve distinct purposes:
- Erosion Control: Focuses on preventing soil loss during construction and protecting landscapes from sediment runoff.
- Stormwater BMPs: Manages stormwater runoff to reduce flooding and improve water quality after construction.
For Maryland homeowners, both are essential for regulatory compliance and maintaining a stable, functional landscape. Erosion control is temporary, used during construction, while BMPs are long-term solutions integrated into site design. Together, they create a comprehensive approach to managing water and soil.
Quick Overview:
- Erosion Control: Prevents soil displacement during construction.
- Stormwater BMPs: Manages water flow and quality after construction.
- Regulations: Maryland requires both strategies for compliance with environmental and construction standards.
Understanding how these systems work together helps homeowners protect their property and local waterways effectively.
Erosion Control: Purpose and Methods
Primary Goals of Erosion Control
The main objective of erosion control is straightforward: to prevent soil from being displaced by natural forces [3]. It’s all about keeping soil particles anchored in place before they can break free and move elsewhere [4].
When soil remains stable, it preserves the integrity of slopes, retains vital nutrients, and keeps sediment from polluting waterways. For Maryland homeowners, this means protecting their landscaping investments. Without proper stabilization, costly grading work, planted areas, and even structural features like retaining walls can be damaged by soil erosion and washout.
These goals guide the selection of specific erosion control methods tailored to different needs.
Common Erosion Control Methods
The choice of erosion control technique depends on the site’s conditions and project requirements.
- Hydroseeding and hydromulching: These methods are quick and budget-friendly ways to establish vegetation on disturbed soil [3]. By spraying a mix of seeds, fertilizer, and mulch onto exposed areas, they provide immediate coverage while vegetation takes root. This approach is especially effective for large areas where traditional seeding would take too long.
- Erosion control blankets and matting: Designed for slopes and embankments, these coverings protect soil from rainfall and runoff [3]. They can be made from biodegradable materials like coconut fiber for short-term use or synthetic options for longer-lasting needs.
- Turf Reinforcement Mats (TRMs): Built for areas with high water flow, TRMs use durable materials to withstand strong water currents that could otherwise erode soil [3]. They are ideal for drainage channels and steep slopes where extra protection is critical.
- Slope stabilization: This method combines tools like geotextiles, strategic vegetation placement, and engineered structures to secure soil on challenging terrain [3]. It not only stabilizes slopes but also ensures their long-term durability.
- Vegetative cover solutions: Using native or adaptive plants, this approach strengthens soil retention over time. As plant roots grow and spread, they create a natural network that binds soil particles together, while also adding visual and ecological benefits [3].
By implementing these techniques, soil stability improves, and stormwater management becomes more effective.
Maryland Erosion and Sediment Control Standards
In Maryland, regulations ensure that erosion control methods are applied consistently across projects. These rules are rooted in the "2011 Maryland Standards and Specifications for Soil Erosion and Sediment Control" [2][5], which all counties and municipalities are required to follow.
The standards cover a wide range of topics, including activities that require permits, plan design requirements, approval processes, inspections, enforcement measures, and stabilization protocols [5]. No building or grading permit can be issued until an erosion and sediment control plan is approved by the proper authority [5].
Permits are required for relatively small disturbances – any land disturbance over 5,000 square feet or involving more than 100 cubic yards of earth typically needs a grading permit [6]. Additional permits are necessary for activities in sensitive areas like wetlands, floodplains, watercourses, stream buffers, tidal water zones, habitat protection areas, or forest buffer zones [6].
One key provision in Maryland’s regulations is that stabilization measures must be implemented even if the erosion control plan is still awaiting approval [5]. This prevents delays in erosion control efforts while permits are being processed.
The approval process itself involves multiple stages, including Concept Plan, Site Development Plan, and Final Plan reviews [7]. For larger projects, professional engineers draft plans according to Maryland Department of Environment (MDE) standards, which are then reviewed and approved by local Soil Conservation Districts [6][7].
Stormwater BMPs: Function and Applications
Primary Objectives of Stormwater BMPs
Stormwater Best Management Practices (BMPs) play a critical role in managing both the quantity and quality of stormwater runoff. Their main aim is to minimize pollutants – like sediment, hydrocarbons, heavy metals, herbicides, nutrients, and litter – before runoff reaches nearby waterbodies. Beyond pollution control, BMPs enhance water storage within a watershed by capturing, holding, and filtering runoff into the groundwater system. This process helps mitigate flash flooding and stream bank erosion, particularly in urban areas with lots of impervious surfaces like roads and rooftops. Together, these efforts safeguard both human health and aquatic ecosystems.
However, it’s important to understand that no single BMP can address all stormwater challenges. Instead, an interconnected system of practices is typically required to tackle the various facets of water management effectively [8][9]. This coordinated approach often works hand-in-hand with erosion control measures, forming a comprehensive water management strategy.
Types of Stormwater BMPs in Maryland
In Maryland, property owners have access to a variety of BMPs tailored to meet different site needs and water management goals. For example:
- Rain gardens and bioretention systems: These are planted depressions designed to capture runoff from surfaces like roofs and driveways. They allow water to slowly seep into the ground while plants and soil filter out pollutants.
- Permeable pavers: Perfect for driveways, patios, and walkways, these surfaces let water pass through to the underlying soil and stone layers, reducing runoff.
- Retention and detention basins: Retention basins hold water permanently, while detention basins temporarily store it, releasing it at a controlled pace to prevent flooding.
- Green roofs, rain barrels, and constructed wetlands: These systems manage rooftop runoff, filter pollutants, and even create habitats for wildlife.
The key to success lies in selecting BMPs that align with a property’s unique conditions, meet regulatory requirements, and can be maintained over time.
Regulatory Requirements for Stormwater Management
Maryland has established stringent stormwater management regulations to ensure effective implementation of BMPs. The Maryland Department of the Environment (MDE) oversees these regulations under the Stormwater Management Act of 2007. This law requires all new development and redevelopment projects to incorporate stormwater management measures [10]. A core aspect of this framework is Environmental Site Design (ESD) to the maximum extent practicable (MEP). ESD involves using small-scale techniques that mimic natural hydrology [10][11].
The Maryland Stormwater Design Manual serves as the go-to resource for technical guidance on design and construction. Local jurisdictions, like Howard and Montgomery counties, are responsible for reviewing and approving stormwater management plans during the permitting process. ESD strategies outlined in the manual include preserving natural features, disconnecting impervious surfaces, using vegetated open channels, and implementing systems like rain gardens, permeable pavements, and bioretention facilities [11].
For homeowners, these regulations often mean that significant landscaping or construction projects will require professional design and approval to ensure compliance with both state and local rules.
Stormwater "BMP’s" Best Management Practices
Key Differences Between Erosion Control and Stormwater BMPs
Erosion control and stormwater BMPs each play a distinct role in creating an effective Stormwater Pollution Prevention Plan (SWPPP) for Maryland landscapes. By examining how these strategies differ and work together, their importance becomes more apparent.
Comparison Table: Erosion Control vs. Stormwater BMPs
| Aspect | Erosion Control | Stormwater BMPs |
|---|---|---|
| Primary Role | Reduces sediment and limits turbidity during construction | Manages runoff and improves water quality on completed sites |
| Implementation | Used temporarily during construction as part of the SWPPP | Incorporated into the final site design for long-term use |
| Role in SWPPP | Provides early protection for water quality during active work | Maintains ongoing runoff control after site stabilization |
Timing is everything in Maryland landscaping projects. Erosion control measures are the first line of defense, installed before any soil is disturbed. These ensure the SWPPP’s goals are met from the very beginning. Once construction wraps up and the site is stabilized, permanent stormwater BMPs take over, providing lasting runoff management.
How They Work Together
Erosion control and stormwater BMPs function as a team within an effective SWPPP. During construction, erosion control prevents sediment from becoming an issue, setting the stage for post-construction BMPs to handle runoff efficiently. A well-designed SWPPP, updated as needed, integrates both measures seamlessly, adapting to changing on-site conditions [12].
This combined approach not only stabilizes landscapes over time but also ensures compliance with Maryland’s regulations.

Combining Erosion Control and Stormwater BMPs in Maryland Landscapes
In Maryland, property owners who merge erosion control measures with stormwater Best Management Practices (BMPs) create a unified water management system. This approach not only addresses various water management challenges but also contributes to protecting the Chesapeake Bay watershed. By combining these strategies, a more cohesive and effective method of landscape protection emerges.
Benefits of Combined Planning
One major advantage of combining these practices is simplified regulatory compliance. Under Maryland’s Stormwater Management Act of 2007, property owners must undergo a thorough approval process for both grading/sediment control plans and stormwater management plans. By integrating these systems, property owners can meet the requirements for federal NPDES permits, such as those for Stormwater Pollution Prevention Plans (SWPPP), while also satisfying local permit standards [1] [9].
Beyond compliance, this combined approach promotes the long-term health of landscapes. Erosion control methods help prevent soil loss, while stormwater BMPs manage runoff and improve water quality [9] [13]. Maryland’s Environmental Site Design (ESD) principles further encourage integration. ESD focuses on small-scale stormwater management techniques, nonstructural approaches, and site planning that mimics natural hydrologic patterns [9].
The benefits of integration also extend to the broader environment. These systems collectively reduce pollutants in stormwater runoff, safeguarding local waterways and the Chesapeake Bay. Since stormwater BMPs are most effective when used as part of a network, combining them with erosion control amplifies their impact [9].
Examples of Combined Solutions
Here are some practical examples of how erosion control and stormwater BMPs can work together:
- Erosion control blankets with rain gardens: The blankets stabilize soil during initial phases, while rain gardens manage runoff over time [9] [13].
- Silt fences around bioretention areas: These fences prevent sediment from clogging infiltration areas during construction and early maintenance stages [1] [9] [13].
- Dry riverbeds with stabilized banks: Dry riverbeds handle stormwater flow during heavy rains, while stabilized banks prevent year-round erosion.
These solutions require careful planning and oversight to ensure they perform effectively over time.

Conclusion
Erosion control focuses on preventing soil loss through stabilization methods, while stormwater Best Management Practices (BMPs) aim to manage runoff volume and quality to minimize pollution. These two strategies play distinct but complementary roles in landscape management, working together to improve water quality across the region. Since stormwater runoff often carries pollutants like eroded soil into local waterways and the Chesapeake Bay, combining these approaches is crucial for effective environmental protection [17].
Some solutions, such as rain gardens, tackle both issues at once. Rain gardens use plant roots to stabilize soil while also capturing and filtering stormwater. Additionally, slowing down the flow of stormwater can reduce soil erosion and prevent damage to streambanks [17]. By integrating erosion control with stormwater BMPs, both soil stability and runoff management are addressed in a more effective way.
However, implementing these systems in Maryland requires expertise tailored to the state’s specific regulatory requirements, soil types, and climate conditions. Proper planning and knowledge are essential for long-term success.
For homeowners in Maryland, adopting these integrated strategies not only protects local waterways but also helps safeguard the Chesapeake Bay watershed. By combining erosion control and stormwater BMPs, the unique environmental challenges of the region can be addressed more thoroughly.
