Maryland’s Critical Area includes all land within 1,000 feet of Maryland’s tidal waters and tidal
wetlands. The Critical Area Commission (CAC) was first created within the DNR in 1984 (Chapter
794, Acts of 1984) to safeguard the Chesapeake Bay from the negative impacts of intense
development. The CAC is responsible for reviewing and approving proposed changes to local
critical area plans; proposals by a State or local government agency that might lead to major
development within a critical area; and, State projects on State-owned land within a critical area.
The CAC meets approximately bimonthly and a CZM staff represents MDNR. New Critical Area
regulations (COMAR 27.02.05.03) went into effect in December 2014 pertaining to sea level rise
and wetland migration areas. These regulations require that when a State agency proposes
development on State-owned land in the Critical Area, the agency shall, to the maximum extent
practicable (a) Incorporate and maintain a wildlife corridor system, including all habitat protection
areas near the development project, so as to connect the largest, most vegetated tracts of land
within, adjacent to, or near the development project and provide continuity of existing wildlife and
plant habitat with other off-site habitat areas; (b) Preserve, protect, and maintain a potential
wetland migration area: (i) Within the area of the development project; and (ii) Adjacent to the area
of the development project, if the agency owns the adjacent land or the adjacent land is within the
agency’s legally enforceable right-of-way.
Maryland’s Coastal Resiliency Assessment
As mentioned above, between 2015-2016 the CMP partnered with The Nature Conservancy to
complete the Coastal Resiliency Assessment. This landscape-level spatial analysis and modeling
effort identified where natural habitats , such as wetlands, provide the greatest potential risk
reduction for coastal communities. CMP staff worked with state, local, federal, and non-profit
stakeholders to identify existing natural infrastructure with resiliency benefits for coastal
communities impacted by climate change. The assessment results include a Natural Features
Analysis, Community Flood Risk Analysis, Marsh Protection Potential Index, and the identification
of Priority Shoreline Areas for conservation or restoration actions. Following release of the Coastal
Resiliency Assessment, the CMP worked with MDNR Land Acquisition & Planning to update the
Program Open Space (POS) Stateside Scorecard to include coastal resiliency data. The POS Stateside
Scorecard evaluates ecological value, public access and recreational opportunities for parcels that
are being considered for acquisition by the state. The Scorecard update ensured that parcels are
now being evaluated for coastal resiliency benefits. This work was further expanded upon the
completion of a CCS-led parcel evaluation tool that allows real-time data return about the habitat
and other key resources located on parcels under consideration for protection.
Resiliency through Restoration Initiative
In 2016, the State of Maryland launched a new program, entitled Resiliency through Restoration,
which is managed by the CMP. The Resiliency through Restoration Initiative directly supports on-
the-ground implementation of nature-based projects, including wetland enhancement projects.
Over the short term, the Initiative will demonstrate how nature can help protect communities from
climate change impacts. Over the long term, the Initiative will reduce Maryland’s vulnerabilities and
enhance resiliency of local communities, economies, and natural resources. These goals will be
reached through the implementation and tracking of pilot projects that will demonstrate how
nature can build community resilience to climate change. Projects include tidal marsh restoration
and other nature-based practices that provide community and ecosystem benefits. Projects are
selected based on the vulnerability of the habitat and community, targeted resiliency areas, level of
community engagement, project readiness and status, and broader ecosystem services. Maryland’s
Coastal Resiliency Assessment is used to screen and prioritize projects.
