United States Army Corps of Engineers Federal Emergency Management Agency Seal of the State of Indiana


Indiana Silver Jackets, North Branch Elkhart River, West Lakes Task Team Report, 2010


A catalyst in developing comprehensive and sustainable solutions to natural hazard issues.


The core agencies will establish an interagency communications team working with other State and Federal Agencies to:

  • enable the effective and efficient sharing of information
  • foster the leveraging of available agency resources
  • provide improved service to our mutual customers
  • promote wise stewardship of the taxpayers investment

Our Story

Indiana's Story (pdf, 11 KB)

Inundation Pilot Study: By bringing together several agencies, the Indiana Silver Jackets team was able to pair up technologies normally not used together to identify flood areas and when those areas would be impacted upon through the use of real time river gauge data. In FY08 the pilot study successfully calibrated the model against actual river flow data for the White River in Indianapolis. Model outputs can now be integrated with the HAZUS damage model, and GIS and local Property Valuation Administration (PVA) databases. This allows local agencies to quickly determine where to focus flood fighting efforts and to quickly provide reliable post-flood damage estimates. Outputs can be read in real time on a web-based system. This should also allow the citizens to be more responsible for their own safety as they will be able to monitor flood progression and plan accordingly. The cost for setting up this system on a typical gauged stream is relatively low, on the order of less than $25K a stream mile. In FY09 and FY10, this system will be expanded to cover as many as 20 other gauged stream locations within Indiana, subject to availability of funding.

Risk Communication: The Silver Jackets team participated in the update to the Indiana State Hazard Mitigation Plan mandated by FEMA. This participation by the member Silver Jackets agencies allowed the Indiana Department of Homeland Security (IDHS) to prepare a more comprehensive and accurate Mitigation plan for their state. The group also continued with prior year education efforts to reach out to children to educate them about flooding and severe weather and the measures they and their families can take to assure personal safety. This project involved a number of the member agencies in the distribution of the activity book materials and outreach to various groups specifically working with children throughout the State.

Response to May/June Flood 2008 Disasters: The Indiana Silver Jackets group assumed the role of the Interagency Levee Task Force in Indiana. Sharing time-critical information was one of the biggest efforts. Members of the Silver Jackets community had points of contact in the other agencies that they could reach quickly for response. One example was that the U.S. Department of Agriculture (USDA) emailed CELRL regarding Emergency Watershed work (stream bank & debris removal) for central Indiana. They had not conducted any recent activities of this nature and their cost data was circa 2003 prices. Within a couple of days CELRL had worked up and supplied to USDA an updated price list for various requested activities. Another example was a request from the Indiana Department of Homeland Security (IDHS) for a listing or a map identifying which dams and levees in Indiana the Corps could support with repairs. They were seeking information to brief upper-level management on what was available for dam and levee repair. Within a business day, a list of the projects had been supplied that would qualify for Corps aid, as well as those projects that would not qualify. The Indiana Silver Jackets also supplied IDHS with the list of those communities that had already contacted the Corps for help. Coordination of post flood responses by the agencies in Silver Jackets has been significantly speeded up and streamlined by their cooperative efforts.


"Silver Jackets allows the State and Federal partners to work seamlessly...and anticipate needs during disaster events.

The Silver Jackets program maximizes the funding available...throughout the state and allows the team members to work together in a synergistic manner, tapping into one another's needs and capabilities, thus creating...services that otherwise would not be available to the local governmental entities or the citizens.

The program allows the partner agencies to look ahead and identify potential challenges and identify solutions to address those challenges before they happen."

—Manuela Johnson, Indiana Dept of Homeland Security


Meetings will be conducted on, at a minimum, a quarterly basis. Coordination may occur through email and teleconferencing.
