FEMA Mitigation Best Practices: Mitigation Alleviates Economic Impact of Flooding at Airport   [open pdf - 34KB]

"The existing crossing at Coal Creek, located at Erie Municipal Airport (EMA), was in desperate need of repair and unable to withstand an annual storm event. The city replaced the culvert through a grant funded by the Federal Emergency Management Agency's (FEMA) Pre-Disaster Mitigation Program (PDM). The culvert system consists of two parallel precast reinforced concrete box culverts, each measuring approximately ten feet in height and twenty feet in width. The ends of both culvert sides were anchored and poured in concrete wing walls approximately 30 feet long and tapered to meet the creek bank. The new system was in place during the September 12, 2013, flood disaster that devastated the state of Colorado. The airport was able to operate during the event, since Coal Creek Crossing was not overwhelmed by the rushing flood waters. The project was initiated on December 12, 2008, and completed on June 6, 2011. The total cost of the project was $417,082.85. PDM pays up to 75 percent of approved projects that will prevent or reduce damage from storms and other natural hazards. PDM funds are designed to assist state and local communities with implementing long-term mitigation measures. EMA is owned by the town of Erie and is strategically located in the Denver-Boulder Metropolitan Area on Colorado Highway 7, three miles west of Interstate 25. The culvert system connects the airport's 4,700-foot-long paved runway to several maintenance facilities. Damages from the annual flood events had deteriorated Coal Creek Crossing to the point that significant repairs were required to keep it operational."
