Maryland Silver Jackets

The Maryland Silver Jackets Team first convened in 2010. The team's activities have included levee risk outreach, holding coastal flood training, conducting nonstructural assessments, holding flood proofing workshops and working on the creation of a flood warning tool. In addition, the team is focused on data sharing among team members, and the Maryland Hazard Mitigation Grant program. 

 

 

 

 

 

 

Team Activities

Flood Warning Tool

The Maryland Silver Jackets team is in the process of developing an innovative tool that predicts flood inundation based on the integration of the National Weather Service's new National Water Model and recent HEC-RAS modeling associated with FEMA's RiskMAP process. The test case for this project is Whitemarsh Run in Baltimore County. 

Flood Proofing Workshops

The Maryland Silver Jackets team held floodproofing workshops at multiple locations throughout the state in August of 2018.  The workshops occurred in Cambridge, Prince Frederick and Hagerstown during the week of August 6th.  The National Nonstructural Floodproofing committee discussed techniques that home and business owners can incorporate to reduce their flooding risk.  The other team partners (MDE, MEMA, FEMA, USACE, etc.) provided information and discussed the types of state and federal programs available to assist communities and homeowners.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 Flood Proofing 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.
