Service Description: In the Chesapeake Bay, relative sea level rise (SLR) is impacting coastal lands at some of the highest rates in the U.S. Identifying long-term planning options to increase resiliency against coastal storm surge, flooding, and erosion is an important step in protecting Maryland’s coastal zone. Much of our natural buffering capacity against these coastal hazards comes from our coastal wetlands. In order to better understand the impacts sea level rise may have on the stat’s coastal marsh system, the Sea-Level Affecting Marshes Model (SLAMM) was run for all 16 coastal counties and Baltimore City. The results of SLAMM were analyzed for specific conservation criteria for long-term planning that may help increase coastal resiliency in Maryland. The conservation criteria include areas that may support future wetland migration; wildlife habitat and corridors; high priority terrestrial living resources; vulnerable wetland habitat; and suitable hydric soils for wetland establishment. From these criteria, a conservation model was developed to prioritize the most important areas for wetland adaptation. As a result, the top priorities were used to create the Wetland Adaptation Areas (WAA) in three future timesteps: 2050, 2070, and 2100. Within the 2021 SLAMM run, it is projected that Maryland’s coastal waters will rise by 1.37 feet in 2050, 2.32 feet in 2070, and 4.03 feet in 2100.

Title: Wetland Adaptation and Vulnerability to Sea Level Rise

Comments: In the Chesapeake Bay, relative sea level rise (SLR) is impacting coastal lands at some of the highest rates in the U.S. Identifying long-term planning options to increase resiliency against coastal storm surge, flooding, and erosion is an important step in protecting Maryland’s coastal zone.
