Green Infrastructure Master Plan

NEW: Updated Draft Plan Prepared for Planning Advisory Board

The initial public comment period for the draft Green Infrastructure Master Plan concluded on September 26. In response to comments received, County staff improved the Plan to include clearer statements that it does not change development regulations or zoning, but focuses on voluntary land conservation. The Plan now clarifies that while recreation can be compatible with conservation, the Plan does not promote trespassing on private property. Additionally, the Plan includes more recommendations on maintenance of the Green Infrastructure Network. The Network map has also been refined based on requests from the public to remove some areas and add others.
The revised draft Plan was introduced to the Planning Advisory Board (PAB) on November 10. At their next meeting on December 8, 2021, the PAB will consider whether to recommend the Plan. Community members can submit written testimony about the draft Plan until midnight on November 28.

Planning Our Green Infrastructure

The Green Infrastructure Master Plan will be a guide to protecting the County's best natural, agricultural, and recreational lands. This plan is an update to the 2002 Greenways Master Plan. The update will use better data to strengthen the ecological, recreational, historic, and cultural assets that support the health of our environment, while also contributing to our social and economic health.

Green Infrastructure includes large, high-quality natural areas and the linear corridors that connect them. These areas include forests, streams, wetlands, and fields. Public ownership protects some areas, such as Federal, State, and County parks. Easements protect other areas that are privately owned. The Green Infrastructure network has many benefits. It improves water and air quality, supports plants and animals, and ensures that residents can continue to enjoy a green and healthy Anne Arundel County.

This Master Plan update is a joint effort between the Office of Planning and Zoning and the Department of Recreation and Parks. We are working together with local, state, and federal government, environmental nonprofits, and the private sector, among other partners. Since the Green Infrastructure Network weaves across the entire County, public participation will be essential. We invite you to explore our resources for more information on how you can stay involved. We also welcome you to email [email protected] with questions and comments.
  • How Will My Community Benefit?

    Green Infrastructure supports scenic views, sustains healthy soils for farming, and provides for recreational trails. It also prevents damage from stormwater runoff and nourishes healthy watersheds and coastline. Some of the other ways in which Green Infrastructure serves you are:


    • Supports wildlife viewing, hunting, and fishinga $1.3 billion dollar industry in Maryland.
    • Increases tourism and expenditures on dining, lodging, and other services.
    • Increases nearby property values by 10-20%.
    • Preserves farmland for agricultural jobs, agritourism, and local food production.
    • Supports clean streams and rivers which in turn support the maritime industry.


    • Protects quality of surface and groundwater resources.
    • Provides for plant and animal habitat and migration corridors.
    • Creates an enjoyable sense of place by protecting natural features and scenic vistas.
    • Helps mitigate effects of climate change such as poor air quality, nuisance flooding, and heat islands.
    • Supports opportunities for active transportation.


    • Provides space to walk, jog, hike, bike, ride horses, canoe, kayak, picnic, fish, hunt, and birdwatch, among other outdoor activities.
    • Opportunity for outdoor exercise creates potential medical cost savings of approximately $1,100 per person per year
  • What Counts As Green Infrastructure?

    This planning process will identify Green Infrastructure "hubs" and "corridors." Hubs are large areas of forest and wetland—at least 250 acres—that buffer natural resources from more intensive land uses. Corridors are linear features at least 200 feet wide that connect hubs. The Plan will also identify areas of contiguous forest that are 75 acres and larger. Interconnectivity of these features supports plants, animal migration, and ecosystem health. Anne Arundel County's Green Infrastructure network includes all the following:

    Natural and Cultural Assets

    • Floodplains, wetlands, streams, and forests
    • Unpaved trails, water trails, and water access points
    • Historic and cultural resources

    Public Lands

    • Parks
    • Federal, State, and County lands acquired for preservation

    Private Lands

    • Land Trusts
    • HOA Parcels
    • Backyards


    • Agricultural easements
    • Open space, forest conservation, floodplain, wetland easements
    • Utility easements
