New Sediment and Erosion Control Standards
Montgomery County has introduced updated standards that now mandate an Engineered Sediment Control Permit for land-disturbing activities exceeding specific thresholds. This move ensures better control of sediment during development, particularly in projects that could affect local waterways. The changes aim to address growing environmental concerns while aligning projects with stricter compliance requirements in future review stages.
Key Changes to Sediment Control Regulations
Compliance Requirements for Landscaping and Hardscaping Projects
The updated sediment control standards have established specific permit requirements based on the size and scope of a project. Knowing these thresholds is crucial for homeowners and contractors to plan effectively and avoid any compliance issues during construction.
Permit Thresholds and Application Types
The type of permit required depends on the scale of the project. For larger projects, the Engineered Sediment Control Permit is necessary. This applies to projects that disturb 5,000 square feet or more of land, involve 100 cubic yards or more of earth movement, or include the construction of a new residential or commercial building [2].
For smaller projects, the Small Land Disturbing Activities (SLDA) permit is available. This option is designed for minor land disturbances that don’t meet the thresholds for an engineered permit [2]. If the only reason your project requires a sediment control permit is due to earth movement exceeding 100 cubic yards, and stormwater management isn’t necessary, the SLDA permit may be a better fit [2].
| Permit Type | Project Thresholds | Key Requirements |
|---|---|---|
| Engineered Sediment Control Permit | ≥5,000 sq. ft. disturbance; ≥100 cu. yds. movement; new building construction | Requires stormwater management design |
| Small Land Disturbing Activities (SLDA) | Minor activities below engineered thresholds | Simplified site plan and cover letter |
| Engineered SC for Single Family Lots | New home on existing recorded lot | Not applicable for townhomes |
Another option, the Engineered Sediment Control Permit for Single Family Lots, is specifically for new home construction on recorded lots. However, this permit cannot be used for townhome developments [2]. Like other engineered permits, it requires stormwater management design as part of the compliance package.
For larger landscaping and hardscaping projects, the inclusion of stormwater management adds complexity but plays a vital role in protecting the environment [2].
With the permit types outlined, the next step involves submitting plans through Montgomery County’s digital system.
Plan Submission and Review Process
In Montgomery County, all sediment control permit applications must be submitted via the ePlans electronic submission system. This system enforces strict formatting and documentation standards, which directly impact the review timeline.
No matter the permit type, following the ePlans formatting guidelines is mandatory. File names must be kept to 15 characters or fewer, each drawing must be uploaded as a separate file, and all documents must be combined into a single multi-page PDF [1].
The documentation requirements differ based on the type of permit. For Engineered Sediment Control (SC) permits, applicants must submit detailed plans that include sediment control and stormwater management designs, along with technical reports and calculations [1]. On the other hand, SLDA permits require only a simplified site plan outlining property boundaries (without sediment control measures) and a cover letter describing the proposed work [1].
Specific technical details are critical for approval. For example, every drawing must have a 3-inch by 4-inch clear space at the top center for county batch stamping [1]. Additionally, all plans must include digital signatures before submission.
Once documents are uploaded, applicants must complete the "Notify County" task in the eForm under the Workflow Portals tab to move forward with the review process [1]. Skipping this step can cause significant delays.
If corrections are needed, revised files should be uploaded to the same folders using the original file names [1]. This ensures that county reviewers can efficiently track changes and maintain organized project records.
While the ePlans system simplifies the overall submission process, it requires careful attention to detail. Projects that meet technical requirements from the start often move through the review process faster, avoiding delays caused by multiple rounds of corrections.

How Updated Standards Affect Project Planning
The updated permit requirements in Montgomery County have reshaped how landscaping and hardscaping projects are planned and executed. These revised sediment control standards influence every stage of project planning, from initial concepts to final approvals, adding new layers of complexity to timelines, documentation, and coordination efforts.
Changes to Project Timelines and Documentation
The new regulations have extended project timelines, meaning property owners and contractors must now factor in longer approval processes. For example, plan reviews for engineered permits typically take 2–4 weeks, while single-family lot permits require 2–3 weeks. However, projects often go through multiple review cycles, stretching the total approval time to 6–12 weeks [2][3]. Early non-compliance with standards often leads to revisions and delays.
The quality of initial submissions plays a huge role in how quickly a project moves through the review process. Well-prepared documentation that addresses all technical requirements can significantly expedite approvals. On the other hand, incomplete or poorly prepared submissions may face repeated correction cycles, adding weeks or even months to the process. Additionally, the speed at which project designers respond to feedback from the Department of Permitting Services (DPS) directly influences the overall timeline [3].
The updated standards have also introduced stricter documentation requirements. Larger and more complex projects now need detailed technical reports, calculations, and supporting materials. This means contractors and property owners must plan further ahead, as the permitting process for these projects will take considerably longer. Starting early is essential to avoid construction delays.
Coordination with Stormwater Management
One of the most impactful changes involves the coordination of sediment control with stormwater management. Projects that include stormwater management components now require Engineered Sediment Control applications, making the approval process more intricate [2][3]. This means projects must address both short-term construction impacts and long-term water management strategies simultaneously.
For example, constructing a new home or adding significant square footage to an existing property that disturbs 5,000 square feet or more typically involves at least two plan review cycles, each lasting 2–3 weeks. Additional approvals, such as Forest Conservation Plans or agreements for Stormwater Management Maintenance, may also be required [3]. These interconnected requirements often create bottlenecks, as securing related permits from various agencies is often necessary before sediment control plans can be approved. Any delays in obtaining these permits can stall the entire project [2][3].
Beyond the approval process, projects now require inspections and certifications for stormwater management measures, adding another layer of coordination with county departments and external agencies [2][3]. This means project schedules must account not only for review periods but also for these additional inspections and certifications.
From a design perspective, landscaping and hardscaping projects must now integrate stormwater management considerations from the very beginning. Treating stormwater management as a separate element is no longer practical. This shift requires more advanced planning and often involves working with design professionals who specialize in both sediment control and stormwater management. For property owners planning large-scale outdoor improvements, these changes emphasize the importance of addressing regulatory requirements during the early stages of design and planning.
Best Practices for Meeting Sediment Control Standards
