Maryland Silver Jackets

The Maryland Silver Jackets Team first convened in 2010.  Its outreach activities include educating residents on the difference between storm surge inundation maps that are part of hurricane evacuation studies and flood insurance rate maps developed for the National Flood Insurance Program.  In addition, the team is focused on data sharing, and the Maryland Hazard Mitigation Grant program. 







Team Activities

Floodproofing Workshops

The Maryland Silver Jackets team held floodproofing workshops at several locations throughout the state in August.  The workshops occurred in Cambridge, Prince Frederick and Hagerstown during the week of August 6th.  The workshops consisted of an afternoon meeting directed towards public officials and an evening meeting for the general public.  Slides for the floodproofing workshops are below:

Which Map Should I Use? Comparing Coastal Inundation Maps

The Maryland Silver Jackets team, working in partnership with the US Army Corps of Engineers, FEMA, and NOAA, developed a short paper for local community officials and residents on the key differences and appropriate uses of Storm Surge Inundation Maps (SSIMs) created as part of a Hurricane Evacuation Study (HES) and Flood Insurance Rate Maps (FIRMs) developed for the National Flood Insurance Program.

Interagency Outreach on Risk and Benefits of New Flood Risk Management Project 

The Maryland Silver Jackets team developed an outreach brochure for the Cumberland-Ridgeley levee systems in Maryland and West Virginia, respectively, to distribute to homeowners, business owners and other stakeholders to communicate the associated benefits and risks of the project. Partners include the Corps, FEMA, National Weather Service, Maryland Department of the Environment and the City of Cumberland. This Corps of Engineers project consists of about 1.6 miles of channel improvements along Wills Creek; 1.7 miles of channel improvement along the North Branch Potomac River; levees and floodwalls on the left and right banks of the North Branch Potomac River; three pumping stations; eight pressure conduits; an industrial water-supply dam; reconstruction of a railroad bridge; track relocations; and reconstruction of piers and abutments for three highway bridges.

Baltimore City Nonstructural Floodproofing Analysis

The City of Baltimore has approximately 8,000 historic structures within the regulatory floodplain, mainly within the neighborhoods of Fells Point, Dickeysville, Mill Valley, Federal Hill and Locust Point.  The Maryland Silver Jackets team investigated potential nonstructural flood proofing measures for these structures in particular.  The City is in the process of developing a design guidance manual for flood proofing these historic structures, and plans to incorporate recommendations from the Silver Jackets report into this guidance document.  The Team surveyed a selection of historic structures selected by the City, and prepared building surveys, analysis and a level of flood risk management recommendations.

Floodproofing Workshops

The Maryland Silver Jackets team will be conducting floodproofing workshops in multiple locations throughout the State, August 7th through August 9th.  The proposed locations for the workshops are (1) Dorchester County, (2) Washington County and (3) the St. Mary's/Calvert County area.  These meetings will consist of an afternoon workshop for public officials and an evening workshop for the general public.  The National Nonstructural Floodproofing committee will discuss techniques that home and business owners can incorporate to reduce their flooding risk.  The other team partners (MDE, MEMA, FEMA, USACE, etc.) will provide information and discuss the types of state and federal programs available to assist communities.
