1. Maryland Chesapeake and Atlantic Coastal Bays Trust Fund Grants
For communities looking to upgrade their stormwater systems, the Maryland Chesapeake and Atlantic Coastal Bays Trust Fund provides much-needed financial assistance. This program has been a cornerstone of Maryland’s efforts to support stormwater retrofits and reduce nutrient and sediment pollution. Since its inception in 1985, the Trust Fund has awarded more than $130 million through over 14,000 grants [4]. Administered by the Maryland Department of Natural Resources (DNR), the program focuses on projects aimed at reducing nonpoint source pollution [3].
Eligibility Requirements
The program is open to a range of applicants, including local governments, forest conservancy district boards, soil conservation districts, academic institutions, and non-profit organizations [3]. Applicants must demonstrate experience in managing projects that address nonpoint source pollution [3].
Funding Amounts and Scope
Under the Watershed Assistance Grant Program, applicants can receive up to $100,000 for project designs or $150,000 for stream restoration, wetland, or living shoreline projects [5].
Application Process and Deadlines
Applications are submitted online via FieldDoc and must include estimates for nitrogen, phosphorus, and sediment reductions. Incomplete proposals are not considered [7][8]. A new award management portal will launch in August 2025, so applicants should download any existing materials and prepare to set up new accounts [6]. Deadlines vary depending on the grant program, so it’s crucial to check the Chesapeake Bay Trust website for the most up-to-date information [6].
For example, on May 28, 2025, the Chesapeake Bay Trust hosted an informational session about the Capacity Building Grant Program.

Additionally, the Chesapeake and Coastal Grants Gateway simplifies the application process. Full details and deadlines can be found on the Chesapeake Bay Trust website [9].
2. Anne Arundel County Property Tax Credit for Stormwater Controls
Anne Arundel County has a program that helps property owners lower their property taxes by installing stormwater management systems. Instead of providing upfront grants, this initiative offers tax credits, making it an appealing choice for homeowners and businesses aiming to reduce their long-term tax bills while enhancing stormwater management on their properties. Here’s a breakdown of the key details you need to know.
Eligibility Requirements
Both residential and commercial property owners in Anne Arundel County can apply for this tax credit. To qualify, the improvements must be voluntary, not legally required, and included on the Department of Public Works’ list of approved stormwater management devices [10].
Eligible practices include living roofs, permeable pavers, bioretention systems, sidewalk infiltration planters, cisterns, and other permanent methods designed to divert or absorb stormwater [11]. However, this credit cannot be combined with other tax credits [10].
Funding Details
The credit covers 10% of the total cost of materials and installation for approved stormwater management projects, with a maximum benefit of $10,000 over a five-year period [10]. This applies exclusively to Anne Arundel County real property taxes [10].
For example, if your project costs $100,000 or more, the tax credit will still be capped at $10,000 over the five years.
Geographic Scope
This program is specifically available to property owners in Anne Arundel County, Maryland.
Application Process and Deadlines
To apply, submit your application within 45 days of completing the stormwater improvements. The application is reviewed by the Office of Finance, and an inspection is conducted to ensure compliance [10]. Once approved, you’ll receive written notification, and the tax credit will take effect in the taxable year following your submission [10].
The County reserves the right to inspect the stormwater system for the duration of the credit period [10]. For stormwater fee credit applications, the submission deadline is October 1st of the taxable year in which you want the credit to begin. Applications received after this date will be considered for the next taxable year if approved [12].
To apply, download the Stormwater Management Tax Credit Application Form and submit it via email to taxcredits@aacounty.org or mail it to:
Anne Arundel County, Office of Finance
Attn: Tax Credits
PO Box 427, Annapolis, MD 21404-0427 [10].
This tax credit is one of several financial incentives available in Maryland to support stormwater system upgrades.
3. Maryland’s $25 Tree Credit
Maryland’s $25 Tree Credit is a simple yet impactful way to encourage tree planting while improving stormwater management. Trees play a critical role in intercepting rainfall, filtering out pollutants, and reducing runoff. By planting more trees, residents can help manage stormwater naturally and contribute to a healthier urban canopy, which reduces the amount of polluted runoff entering local waterways and the Chesapeake Bay [14][15].
How the Program Works
This program offers a $25 discount for the purchase of any tree priced at $50 or more [13]. Essentially, it covers half the cost, making it easier for Maryland residents to invest in their landscapes while supporting environmental health. While the discount per tree may seem small, widespread participation can make a big difference in reducing polluted runoff across the state.
Where You Can Use It
The tree credit is available at participating nurseries and garden centers throughout Maryland [13]. Because of its statewide reach, both urban and rural residents can take advantage of this program, making it accessible to a wide range of communities.
How to Apply
Getting the $25 credit is straightforward. Visit www.trees.maryland.gov to download a printable coupon. Bring the coupon to a participating nursery or garden center, choose a tree priced at $50 or more, and enjoy the $25 discount at checkout. Keep in mind that each coupon applies to one qualifying tree [13].
If you’re working on a larger landscaping or stormwater management project, professional advice can make a big difference. For tailored guidance, you might want to consult Pro Landscapes MD, a service provider specializing in central Maryland. They can help you seamlessly incorporate tree planting into your broader stormwater management strategy, ensuring your efforts are both effective and well-integrated.

6. Montgomery County Stormwater Infrastructure Rehabilitation Program
Montgomery County, Maryland, runs a focused program aimed at addressing stormwater challenges, particularly in its parklands. This initiative is part of a broader effort across the state to manage stormwater runoff through targeted retrofits and improvements. The program tackles issues caused by impervious surfaces like roads, parking lots, and buildings, which lead to excessive stormwater flow into local streams during heavy rains [22]. By combining regulatory requirements with community-focused environmental improvements, the program delivers both compliance and ecological benefits.
The approach includes retrofitting impervious surfaces and implementing green infrastructure to enhance drainage and improve riparian zones [22].
Geographic Focus Within Maryland
This program is specific to Montgomery County Parks, which operates under a National Pollutant Discharge Elimination System (NPDES) permit. This permit regulates stormwater pollution within parklands [22]. However, the municipalities of Rockville, Gaithersburg, and Takoma Park are not included, as they manage their own stormwater systems [23].
Funding and Project Scale
Montgomery County has partnered with the Chesapeake Bay Trust on a project with a total budget of $628,664, combining $500,000 in funding from the EPA with $128,664 from the county. These funds support a variety of community projects [24].
The program encompasses projects of different sizes across ten community locations, with individual subproject costs ranging from $29,125 to $107,672 [24]. Here’s a breakdown of a few key projects:
| Project | Federal Share | County Share | Total Cost |
|---|---|---|---|
| Little Falls Watershed Alliance – St. Dunstan’s Church | $20,369 | $8,756 | $29,125 |
| Sandy Spring Museum | $76,141 | $19,035 | $95,176 |
| Rock Creek Conservancy – Strathmore | $86,138 | $21,534 | $107,672 |
These efforts deliver tangible outcomes, including conservation landscaping, raingardens, tree planting, and the use of pervious pavement to better manage stormwater [24].
Application Process and Deadlines
Each fiscal year, Montgomery County allocates funds to projects through an internal planning process [22]. Unlike traditional grant programs, this initiative works through partnerships with established organizations rather than accepting open public applications.
Currently, several projects are at different stages of development. For instance, the Colesville Local Park has completed its micro-bioretention stormwater retrofit. Meanwhile, Kemp Mill Estates Local Park and Glen Hills Local Park are in the design phase. Construction is underway for projects like Glen Hills Local Park’s 200 linear feet of outfall enhancement and improvements at Sligo Creek Stream Valley [22].
For the latest updates on timelines and partnerships, interested parties can reach out to the Project Manager [22].
Pro Landscapes MD brings valuable expertise in stormwater management and green infrastructure, making them a great resource for Montgomery County property owners looking to implement similar solutions on private properties.

Each program has its own strengths and limitations. For instance, the Maryland Chesapeake and Atlantic Coastal Bays Trust Fund offers some of the highest funding amounts but is only open to local governments and nonprofits, leaving out individual property owners [13]. On the other hand, the Anne Arundel County Property Tax Credit is specifically tailored to homeowners, providing direct financial incentives for installing stormwater controls like rain gardens [13].
Geographic focus is another factor to consider. While some grants, like the Maryland’s $25 Tree Credit, are available statewide, others, such as the Prince George’s County Stormwater Stewardship Grant, are limited to specific areas and may require partnerships for applicants outside those regions [2]. Additionally, application timelines vary – some programs, like the property tax credit, accept applications year-round, while others, like the Prince George’s County grant, follow set deadlines.
Conclusion
Maryland communities have a unique chance to reshape their stormwater management systems with the help of grant funding. Prince George’s County, for instance, has made a meaningful impact by supporting 166 projects that combine environmental restoration with community benefits.
The success of these grants is evident in real-world examples. In 2015, Accokeek First Church of God used a $75,000 grant to adopt stormwater management practices and host educational initiatives[2]. The Alice Ferguson Foundation, in 2014, received $187,697 to enhance water quality at the Potomac Watershed Study Center while educating the public on stormwater issues.

These projects demonstrate how grant programs play a key role in improving water quality. They fund impactful stormwater solutions, reduce runoff pollution, and engage communities in protecting their waterways[1][13]. As stated by the Prince George’s County Stormwater Stewardship Grant Program:
"The Prince George’s County Stormwater Stewardship Grant Program (PGCSSGP) funds on-the-ground restoration and program activities that improve communities and water quality and engages County residents in the restoration and protection of local waterways." [1]
Maryland’s grant programs offer a variety of opportunities for action. Whether you’re part of a local government, nonprofit, community group, or a private property owner, there’s funding available to suit your needs. For example, the Maryland Chesapeake and Atlantic Coastal Bays Trust Fund offers grants exceeding $1 million[13], while smaller-scale programs, like the $25 tree credit, support individual efforts.
When paired with professional expertise, these grants can drive lasting change. Pro Landscapes MD ensures that projects funded by these programs are not only technically sound but also create outdoor spaces that are both functional and environmentally conscious. This approach helps safeguard water quality for generations to come while enhancing the beauty and utility of local landscapes.
