Waterfront Homeowners Guide
Anne Arundel County is lucky to have over 533 miles of shoreline. It offers stunning views, an incredible diversity of recreational opportunities, and supports a vast array of fish, shellfish, and wildlife that are iconic to the Chesapeake Bay. As a waterfront homeowner, the actions you take to manage and protect your property are essential for preserving our waterways as a special place for future generations. By offering opportunities to waterfront homeowners, the information below are simple ways to protect and enhance waterfront properties. What you and your neighbors do to sustain or improve water quality will have positive effects well into our future.
Where the land meets the water is an amazing area full of life with many plants, animals, and fish that spend all or part of their lives. How the waterfront, including the upland, wetland, and water areas are managed determines waterway health. An undeveloped shoreline will have a mix of trees and shrubs, flowers, grasses (native), ferns, and aquatic plants in the nearshore areas. This natural vegetation buffer helps keep our streams, creeks, and rivers healthy by protecting the shoreline from erosion; providing homes, food, and refuge for fish and wildlife; and filtering pollutants from runoff.
Critical Area Law - Protecting Sensitive Lands
In 1984, growing recognition of the importance of this land closest to the tidal waters of the Bay, led to passage of the Chesapeake Bay Critical Area Law. Development or other activities in this 1,000-footwide strip—the Critical Area— disproportionately affect both Bay and tributary water quality. If you live within 1,000 feet of tidal waters or tidal wetlands, you live in the Critical Area. The law mandates additional care when grading, clearing, pruning or clearing invasives.
The 100-foot land strip closest to the water—known as the Critical Area Buffer—has even more stringent requirements. Proper maintenance of trees and shrubs, with little or no use of pesticides, herbicides and fertilizers is especially important since these chemicals can wash or seep into surrounding waters. Since the Critical Area encompasses such a large swath of land, the Critical Area Commission (CAC) relies on citizen oversight for possible violations. The Anne Arundel County Department of Inspections and Permits enforces critical area regulations. Landowners must receive approval for disturbance of soil or vegetation within this zone, including the building of any new structure. More information about Anne Arundel County's Critical Area Program is available here.

- Critical Area Program FAQ'sWhat is the Chesapeake Bay Critical Area?The Critical Area is the land area 1,000 feet inland from tidal water or tidal wetlands. The Chesapeake Bay Critical Area Program promotes more sensitive development within the Critical Area to help protect water quality and wildlife habitat. Of particular importance are restrictions on construction, clearing, and vegetation management within the minimum 100-foot buffer along the shoreline.What is a buffer in the Chesapeake Bay Critical Area?The minimum 100’ buffer is a naturally wooded area or a forested area specifically established or managed to protect aquatic, wetland, shoreline, and terrestrial environments from man-made disturbances. The Chesapeake Bay Critical Area buffer is located 100 feet inland from the mean high water line of tidal water, tidal wetlands, or tributary streams. The 100-foot buffer is expanded to include any contiguous sensitive areas, including all land within 50 feet of the top of a steep slope.I live in the Critical Area and I have a dead tree that I want to remove. Do I need a permit?Yes. All vegetation removal including dead or damaged trees requires an approved Vegetation Management Plan prior to removal.If I propose to remove a live tree or clear live vegetation in the Critical Area, will I have to replant anything?Yes. Critical Area law requires replacement planting for any clearing activity in the Critical Area. Replanting is to be accomplished with native plant species.My realtor told me that I could cut any trees on my waterfront lot that are less than 4 inches in diameter, and I don’t need a permit. Is this true?No, this is NOT true! We hear this question at least several times a week. All trees of any size, as well as shrubs and vines, are considered habitat in the Critical Area and are subject to the Critical Area law requirements. Please contact the Forester in the Compliance Division of Inspections and Permits (410) 222-7441 BEFORE you cut any trees on your waterfront lot.When is a vegetation management plan (or buffer management plan) required in the Chesapeake Bay Critical Area?Any disturbance in the 100-foot or expanded buffer will require a buffer management plan approved by Inspections and Permits. Disturbance includes cutting or removing vegetation (trees, shrubs, vines) and any grading or filling activity.In addition to a buffer management plan, a property owner may need approval from the Department of Inspections and Permits. This approval comes in the form of a grading permit for disturbances greater than 5,000 square feet. For disturbances under 5,000 square feet, a property owner may seek approval of a more simplified, standard grading plan (also known as standard lot sheet) instead of a grading permit.Who prepares a buffer management plan?For removal of individual trees, construction of nonstructural water access paths, and small-scale tree pruning, the property owner can prepare and sign a standard buffer form. For removal of a large number of trees, large scale pruning, and replacing vines and briars with desirable understory plants, the property owner will likely need a buffer management plan prepared by a professional.Can I remove invasive species (phragmites, English ivy, poison ivy, greenbriar) from my buffer?Yes. The County encourages the removal of invasive species. However, you must have a County-approved vegetation management plan and plant the area with native species that suppress the re-growth of the invasive species. Contact the Forester in the Compliance Division of Inspections and Permits at (410) 222-7441 for a list of native species plants or see the For more information Link below. .What does the County do with the fees it collects from property owners for the removal of trees in the Chesapeake Bay Critical Area?The County uses that money to replant trees elsewhere within the Chesapeake Bay Critical Area
Best Practices for Waterfront Homeowners - Waterfront living provides a lifetime of memories. Recognizing your role in caring for the shoreline ensures that you—as well as future generations—will be able to enjoy our shared marine resource.
- Limit your use of pesticides and fertilizersThese chemicals will be washed off your lawn and ultimately into the Bay. Pesticides can harm aquatic life such as fish and amphibians, and fertilizer releases phosphorus into our waterways, which can cause algal blooms that deplete oxygen and block sunlight in the water. If you do fertilize your lawn be sure to follow label instructions precisely and familiarize yourself with Maryland's Lawn Fertilizer Law.
- Properly dispose of household hazardous wastesOnce they enter the storm drain system, hazardous chemicals end up in the Bay, harming fish, birds, and other wildlife. Always take toxic household and yard products to a Household Hazardous Waste Collection Day. Click here from more information and schedule.
- Minimize shoreline erosion
As a waterfront property owner you undoubtedly want to protect your investment and its unique shoreline environment. Protecting a shoreline from accelerated erosion without installing a seawall or bulkhead, can be challenging, but there are alternatives to seawalls. There are many techniques available to address shoreline erosion while supporting the ecosystem and protecting your property. Each site is unique and therefore generally requires a customized solution using a variety of different methods. Understanding shoreline erosion and developing solutions can be very simple or complex depending on the site characteristics.
Characterizing your site starts with simply observing the conditions on and around your property. In many cases you will need the assistance of a professional to complete the assessment which will provide an understanding of the interactions between coastal, geologic, and ecological processes at a site. A thorough assessment of your site is the first step towards protecting both your property and the environment and will allow you to better understand the opportunities and constraints of your property. This step allows you to determine if action is required, and if so, which approaches will be the most effective.
To learn more about "living shorelines," a design approach that both protects property and preserves the natural values of the tidal interface, visit MD DNR's "Living Shoreline" page.
- Is there funding assistance for shoreline erosion work?Yes, the Maryland Department of Natural Resources has some fund available for eligible shoreline projects through its Shoreline Conservation Service Loan Program: https://dnr.maryland.gov/ccs/Pages/livingshorelines.aspx . Community or HOA living shoreline projects may also be eligible for Anne Arundel County Restoration Grant funding if they meet qualifying conditions. More information on that program can be found here.
- Are there permits required for shoreline protection and restoration work?Yes, the MD Department of the Environment (MDE) handles bulkhead and shoreline permitting, and more details can be found here.
- Inspect and maintain your septic system regularlySome waterfront homeowners in Anne Arundel County utilize a septic system, although some communities have converted to public sanitary sewer systems. Owners of private septic systems have a responsibility to protect their family’s health, as well as to protect the surface and groundwater from contamination.
Properly functioning systems are designed to remove most disease-causing human pathogens, but generally are NOT designed to remove or treat water-soluble nutrients or pollutants. The more water and material that goes into your septic system, the more that comes out into your drain field. Recent research on septic systems located in sandy soils has found both phosphorus and nitrates migrated underground over 150 feet from drain fields. If these nutrients seep underground into the lake, aquatic plant growth and algae blooms are likely results.
Malfunctioning systems are especially harmful. Effluent from failed systems can result in direct contamination of well or surface water and could cause serious human health risks. Reasons for septic system failure may include advanced age, overloading, poor site placement and/or poor maintenance.
EVIDENCE OF A MALFUNCTIONING SEPTIC SYSTEM:
- Sewage backing up in the basement or drains.
- Ponded water or wet areas over the drain field.
- Bright green grass over the drain field.
- A dense stand of aquatic plants along only your shoreline.
- Sewage odors.
- Bacteria or nitrate in nearby well water.
If you're interested in upgrading your existing waterfront septic system to a less polluting alternative, the Anne Arundel Health Department has grants to assist with that work.
- Minimize stormwater runoff
Many activities we conduct near the waterfront, in our lawns and gardens and around our home, impact water quality. These activities are even more critical to waterfront homeowners because runoff doesn't have far to travel before reaching the water. When it rains or the snow melts, the water runs off streets, driveways, rooftops and lawns across the landscape and picks up various pollutants like oils, greases, nutrients, fertilizers and sediment. Impervious surfaces speed up the flow of runoff from the landscape and prevent water from soaking into the ground where it can be naturally cleansed by microorganisms that live in the soil.
Solution: Address runoff before it leaves your property. Better yet, keep water on your property for use in areas such as your garden. Redirect downspouts away from hard, paved surfaces into vegetated areas, such as a rain garden, or into a rain barrel for later use in the garden. Rain gardens are growing in popularity because they look great and filter pollutants out of runoff allowing clean water to infiltrate and replenish groundwater supplies. Use porous landscaping materials, such as brick paving stones, sand or gravel beds and mulched areas, allowing spaces where water can infiltrate around and through the materials.
The key to successfully managing rain on your property is to Slow it down, Spread it out, Soak it up. For some simple (and beautiful) ways you can capture stormwater visit the Anne Arundel County Watershed Stewards for ideas.
- Protect or restore your waterfront buffer
If you have native vegetation along your shoreline, consider yourself and the local wildlife fortunate. A mature native buffer represents many years of nature at work and discourages undesirable, exotic plants and animals while attracting songbirds, butterflies, and other wildlife.
If you have lawn to the water’s edge, a simple, no-cost way to get started in restoring your shoreline is to stop mowing next to the water. Seeds in the soil will germinate and valuable native plants will begin to reappear. If you have lawn to the water’s edge and would like to play a more active role in restoring your shoreline, you can replant native trees, shrubs, grasses and wildflowers to attract songbirds and butterflies. The main area where water runs off your property is the best location to start planting to improve water quality. You can create a natural, appealing waterfront landscape while eliminating expensive and time-consuming lawn care.
Natural shorelines contain a lush mixture of native grasses, flowers, shrubs and trees that help to filter polluted runoff and provide important habitat for animals in the water and on the land. The trees, shrubs and plants not only help shelter and create privacy for the homeowner, but may also act as a noise buffer. Larger areas of natural shoreline provide more benefits. However, any amount of natural shoreline is better than none.
