Maryland Grading Permit Requirements
Securing a grading permit in Maryland requires careful attention to detail and adherence to specific county regulations. Properly preparing your application not only helps avoid delays but also ensures your project complies with environmental standards.
Required Documentation
To apply for a grading permit in Maryland, you’ll need several key documents. These typically include:
- Grading Permit Application Form: This form captures essential details about your project and contact information.
- Site Plan: A detailed map outlining the boundaries of disturbance, existing topography, and proposed changes.
- Erosion and Sediment Control (E&S) Plan: This plan specifies measures like silt fences, sediment basins, and temporary stabilization to prevent soil erosion during construction.
- Stormwater Management (SWM) Plan: A document explaining how runoff will be managed both during and after construction.
For larger projects, additional requirements come into play. Counties may ask for a soils report, prepared by a geotechnical firm, to analyze soil conditions and determine the best approach for grading. Cost estimates for erosion control and stormwater management are also often required to outline the scope and budget of the project. These documents must address critical aspects like drainage, grading elevations, and runoff control to meet regulatory standards.
Lastly, it’s crucial to review the specific requirements of your county to customize your application accordingly.
County-Specific Rules
Each Maryland county has its own thresholds and documentation requirements for grading permits. Understanding these differences can help streamline the process and avoid unnecessary complications.
| County | Permit Thresholds | Key Documentation Required | Notable Requirements/Steps |
|---|---|---|---|
| Montgomery | >5,000 sq. ft. or 100 cu. yds. | Grading plan, E&S plan, soils report, TTCP | Bond, pre-construction meeting, inspections |
| Carroll | 5,000–30,000 sq. ft.; >30,000 sq. ft. | Application, affidavit, E&S plan, state/federal permits | Owner/contractor info must match exactly |
| Frederick | >30,000 sq. ft. or 500 cu. yds. | Online application, cost estimates, plans | Major grading permit required for large projects |
| Prince George’s | >5,000 sq. ft. or 100 cu. yds. | Online application, plans, E&S plan, SWM plan | Submission via online portal |
| Baltimore | >5,000 sq. ft. or 100 cu. yds. | Online application, project description, plans | Streamlined online process |
Counties like Montgomery and Carroll require pre-construction meetings and inspections, with permit reviews typically taking 2–3 weeks. After all approvals and bond postings, permits are issued within 1–2 weeks. Carroll County, in particular, differentiates between smaller and larger projects, with more documentation and stricter requirements for larger developments. Frederick County sets a higher threshold for major grading permits, requiring extensive documentation for projects disturbing over 30,000 square feet or 500 cubic yards.
Prince George’s County offers an online portal for submissions, though the review process can take up to 3–5 months. Meanwhile, Baltimore County’s online system is designed to be especially user-friendly, simplifying the application process.
Given these variations, consulting your local county office for precise guidelines is essential.
Professional Involvement
Once you’ve gathered the required documents and understand the county-specific rules, engaging a licensed professional becomes a critical step.
In Maryland, grading plans must be prepared, signed, and sealed by a licensed professional engineer or landscape architect. This ensures that your plans meet technical standards and comply with regulations. Professionals bring expertise in areas like soil mechanics, drainage design, and environmental considerations, which can help streamline the approval process.

Some counties may also accept plans from licensed land surveyors or landscape architects for certain projects, so it’s important to verify acceptable credentials for your specific case.
How to Apply for a Maryland Grading Permit
Once you’ve gathered your documents and familiarized yourself with your county’s specific requirements, the application process becomes much easier to navigate. Maryland counties have introduced user-friendly systems to simplify submissions, and following the right steps can help you avoid unnecessary delays.
Preparation and Submission
Start by organizing all necessary documents and filling out the grading permit application form accurately. Errors or missing information can lead to delays or even rejection.
Many Maryland counties now rely on electronic submission systems, which have transformed the application process. For example, Montgomery County uses ePlans, Prince George’s County operates through the Momentum portal, and Frederick County has its own Application Portal [1][5][3]. These platforms allow you to upload documents, track your application in real time, and communicate directly with reviewers. Make sure your submission aligns with the specific requirements outlined by your county.
Your plans must be properly scaled and signed by a Maryland-licensed professional engineer [1][6]. These plans should clearly indicate the limits of disturbance, existing topography, and any proposed changes.
Permit fees differ depending on the county and the size of your project. The electronic systems will calculate these fees automatically based on your project details, so ensure your square footage and cubic yard measurements are precise [1][2][3].
Once your application is submitted, the next step is to understand how the review process affects your project timeline.
Review and Approval Process
The review process plays a big role in determining your project schedule. Montgomery County typically completes review cycles within 2–3 weeks per cycle [1]. In contrast, Prince George’s County’s standard reviews can take up to three months [5]. However, these timelines can stretch further if your application requires multiple review cycles due to issues or missing details.
Through the electronic portals, you’ll receive real-time updates on your application’s status. If reviewers have comments or need revisions, the system will notify you. Addressing these comments quickly is key to avoiding further delays.
Delays often stem from common issues such as incomplete erosion control plans, missing stormwater calculations, or unclear grading elevations.
For those in Prince George’s County, expedited review is an option if you hire peer reviewers [5]. While this comes with additional costs, it can be a worthwhile investment for larger commercial projects where time is critical.
For complex projects that involve multiple agencies, plan for longer review periods. Reviews for environmental impact, utility coordination, and stormwater management can add months to the process, especially if your project affects sensitive areas or requires detailed documentation.
Once your permit is approved, the focus shifts to meeting on-site requirements before starting any grading work.
Post-Approval Requirements
Getting your permit approved is just the beginning. There are several steps to complete before you can start grading.
All Maryland counties require pre-construction meetings, which include the property owner, grading contractor, and a county inspector [2][1]. These meetings ensure everyone understands the permit requirements, reviews site conditions, and confirms that sediment control structures are properly installed.
After the meeting, inspectors will check that erosion control measures are in place and stabilized [1][2]. This includes verifying that silt fences, sediment basins, and temporary stabilization measures are installed according to the approved plans. No earth-moving can begin until these steps are completed.
Before finalizing the permit, you’ll also need to post bonds. These bonds are calculated based on your submitted cost estimates and ensure compliance with sediment and erosion control requirements [1][2][3]. The bond amount varies depending on the size and complexity of your project, and it will be released once all disturbed areas are properly stabilized after project completion.
This final stage usually takes 1–2 weeks after initial approval, provided all requirements are met promptly.
For a smoother process, consider working with experienced professionals like Pro Landscapes MD. They specialize in preparing compliant documentation, managing communication with county officials, and coordinating inspections, helping you move through the process efficiently and start your project without unnecessary delays.

Erosion Control and Stormwater Management
Erosion control and stormwater management are essential components of grading projects in Maryland. These systems not only protect your property from water damage but also ensure compliance with state and local permit requirements. Properly integrating these measures can help you avoid unnecessary expenses, delays, and regulatory issues.
Erosion Control Measures
In Maryland, every grading permit application must include a finalized erosion and sediment control plan [2][7]. This plan outlines the steps necessary to prevent soil erosion and water pollution during construction.
Key erosion control measures include silt fences, sediment basins, stabilized construction entrances, and temporary seeding [2][7]. For example:
- Silt fences act as barriers around disturbed areas, trapping sediment and preventing it from washing away.
- Sediment traps or basins collect runoff, allowing sediment to settle before water flows downstream.
- Temporary stabilization techniques, such as straw mulch or hydroseeding, protect exposed soil between construction phases.
Additionally, check dams in drainage channels slow water flow and reduce erosion in natural waterways that cross your site. These measures, recommended by Maryland’s Department of the Environment, are often implemented by experienced contractors [2][7].
Before any earth-moving activities begin, Maryland inspectors will confirm that sediment control structures are properly installed and stabilized during a pre-construction inspection [2]. Effective erosion control not only protects your site during construction but also lays the groundwork for successful stormwater management.
Stormwater Management Compliance
For projects disturbing more than 5,000 square feet, stormwater management systems are required [3][6]. Maryland’s SWM standards and COMAR regulations mandate solutions that manage runoff, prevent flooding, and protect water quality. These systems often include features like retention ponds, infiltration trenches, bioswales, and permeable surfaces [1][7].
Your stormwater management plan must include engineered calculations to prove compliance with local and state requirements. This typically involves hiring a licensed engineer to design systems tailored to your site [1][7]. Here are some common components:
- Retention ponds store large amounts of runoff and release it gradually.
- Infiltration trenches allow water to seep into the ground, reducing surface flow.
- Bioswales use vegetation to filter pollutants and manage water flow.
- Permeable surfaces, such as porous pavement, let water pass through instead of running off.
For commercial projects, a three-phased review and approval process ensures stormwater systems align with the overall grading plan and meet all regulatory standards [6]. Regrading is often a critical step, reshaping the land to direct water toward collection points and away from structures. Professional contractors can design and implement these systems to ensure both functionality and compliance. Beyond installation, maintaining system performance over time is crucial.
Long-Term Compliance Tips
Meeting initial permit requirements is just the beginning – ongoing maintenance is essential to keep your erosion and stormwater systems effective. Strategic planning during the design phase can help reduce long-term upkeep.
- Native plantings offer durable erosion control with minimal maintenance. These plants are suited to Maryland’s climate and soil, making them more resilient than non-native species.
- Mulching around vegetation helps retain moisture, prevents soil erosion, and reduces the need for frequent replanting.
- Stabilized slopes using methods like terracing or retaining walls provide structural support while allowing vegetation to establish deep root systems for added stability.
For stormwater management, options like French drains and dry riverbeds are low-maintenance solutions that effectively handle water flow and enhance your landscape’s appearance. Rain gardens are another versatile choice, managing runoff while creating visually appealing planted areas that require little upkeep once established.
Regular inspections are vital to ensure long-term compliance and avoid fines or permit issues [2][6]. This includes checking sediment barriers, clearing debris from drainage systems, and maintaining healthy vegetation.
