2022 Water Resources Element Guidance Update
The Water Resources Element (WRE), a statutory requirement for local comprehensive plans, is designed to ensure that local plans for growth and development can be supported given limitations and constraints of water resources and water, sewer and stormwater infrastructure. This WRE Guidance Update provides best practices for considering and addressing water-related climate change impacts, and for addressing the challenges that growth and development pose to our collective efforts to protect and restore Maryland waterbodies. The WRE Guidance Update outlines best practices and is an advisory document. Comprehensive planning, including WRE development, is a local government decision.
Coast Smart Climate Ready Action Boundary (CS-CRAB) Map
The Coast Smart Climate Ready Action Boundary (CS-CRAB) map was developed in a multi-agency effort by the Maryland Coast Smart Council to identify and mitigate future flood risk to the state's existing infrastructure. The data product was created leveraging existing FEMA regulatory boundaries and infusing an additional three feet of water elevation to determine the new water surface elevations and potential flooding extents (up and out).
The benefits people gain from the environment can be collectively referred to as Ecosystem Services, which are commonly divided into four major categories: provisioning services (e.g. timber, firewood, food), regulating services (e.g. water purification, wildlife habitat), supporting services (e.g. nutrient cycling, soil formation) and cultural services (e.g. recreation, spiritual benefits.
Maryland Coastal Atlas
The Coastal Atlas is a mapping tool that allows state and local decision-makers to visually analyze and explore coastal and ocean data layers for project and planning purposes. Using the built-in tools, the user can query, map, and analyze spatial data to better understand Maryland's marine resources.
Maryland Land Use / Land Cover 2010
The Land Use & Cover map and data is used to show development trends on the landscape in Maryland.
Maryland Protected Lands Dashboard
The Maryland land preservation dashboard is designed to let you assess the current status of Maryland's land preservation efforts and to access the tabular data that informs the dashboard as well as available land preservation GIS data.
Maryland Public Water Access
This web page provides information on public water access sites in Maryland. Sites listed include boat ramps and soft launches (specifically for non-motorized vessels).
Maryland’s Plan to Adapt to Saltwater Intrusion and Salinization
Pursuant to Chapter 628 of the 2018 Laws of Maryland, the Maryland General Assembly tasked the Maryland Department of Planning (Planning) to “establish a plan to adapt to saltwater intrusion,” in consultation with the Maryland Departments of Natural Resources, Environment and Agriculture, Planning presents in this plan, as a result of collaboration with many state agency, university, and other partners, a first state-level report on this issue. The plan is a first step towards better understanding and addressing saltwater intrusion and salinization in Maryland. To varying degrees, saltwater intrusion and salinization already impacts Maryland’s groundwater, surface waters, wetlands, coastal forests, agriculture and infrastructure; however, there is currently no comprehensive understanding of all of the areas currently at risk, and limited knowledge of which areas are at risk in the future. To determine current and future areas at risk, extensive research, modeling and monitoring is recommended.
Maryland's Green Infrastructure Assessment
The Green Infrastructure Assessment (GIA), based on principles of landscape ecology and conservation biology, identified an ecological network using satellite imagery to characterize land cover, Geographic Information System (GIS) data on road, stream, wetland and other resource features, and biological databases.
Maryland's Tier II Waters
MDE Storymap of Tier II Waters describes how Maryland protects its Tier II streams on a watershed scale, to better ensure that downstream high quality waters are maintained.
MERLIN-Maryland’s Environmental Resource & Land Information Network
Maryland's Environmental Resources and Land Information Network (MERLIN) Online allows users to produce a custom map of any location in Maryland, to include their choice of base maps and data layers.
