"Hazard Mitigation Grant Program (HMGP) and Pre-Disaster Mitigation (PDM) funding can be sought for 'grouped' safe room projects. These projects typically consist of multiple buildings for which a safe room for less than 16 people is desired on the building property to protect occupants from extreme wind events. The subapplication may be developed by a local or State agency with outreach to owners of potentially participating properties. These projects are done using 'rebates': each building owner obtains a contractor to install the safe room and is reimbursed for 75-percent (up to a predetermined limit) of the individual safe room project cost. A subapplication that is requesting funds for a safe room rebate project should understand the specific requirements for this type of project to be able to be fully reviewed by FEMA [Federal Emergency Management Agency]. The following items are some of the key components of a thorough safe room rebate subapplication."
