FEMA – Funded Culvert Replacements

Tectonic worked closely with the Town of Warwick to provide multi-discipline engineering services on various culverts and Town roadways that were destroyed after Hurricane Irene and Tropical Storm Lee in August/September 2011. The Federal Emergency Agency (FEMA) declared the region eligible for disaster relief funding and the project was performed under an expedited emergency repair framework. Tectonic coordinated with municipal staff to assess the town-wide damage inflicted by the storms and estimate damages. Ten locations were determined to be “large” FEMA projects and required engineering and permitting to facilitate replacement.

Tectonic performed multiple engineering services at six of the ten locations:

  • Cascade Road (arch culvert to permit fish passage on a regulated watercourse)
  • Black Rock Road (arch culvert to permit fish passage on a regulated watercourse)
  • Bowen Road (arch culvert to permit fish passage on a regulated watercourse
  • Distillery Road (box culvert)
  • Jessup Road (arch culvert to permit significant flow passage)
  • Ketchum Road (box culvert)

Tectonic’s services included:

  • Topographic surveys
  • Geotechnical subsurface investigations for culvert and wingwall foundations
  • Hydraulic modeling (Federal Highway Administration HY-8 Culvert Hydraulic Analysis Program) of the proposed improvements to size the culverts
  • Design and permitting plans generation
  • Permitting of the site (New York State Office of Parks and Historic Preservation, US Army Corps of Engineers emergency general permitting, New York State Department of Environmental Conservation emergency Protection of Waters, U.S. Fish and Wildlife Service)
  • Construction documents
  • Public bid and construction support
