Betterments: Examples of Eligibility

The following examples, listed in the ER Manual, may help protect highway facilities from possible future damage and as a result may be approved:

  • Raising roadway grades
  • Relocating roadways to higher ground or away from slide-prone areas
  • Stabilizing slide areas
  • Stabilizing slopes
  • Installing riprap
  • Lengthening or raising bridges to increase waterway openings
  • Deepening channels
  • Increasing the size or number of drainage structures
  • Replacing culverts or low water crossings with bridges
  • Installing seismic retrofits on bridges
  • Adding scour protection at bridges
  • Adding spur dikes

Each of these items would likely increase the resiliency of a repair and thus may be eligible for ER funding; provided they are economically justified. Develop a Betterment alternative that will be effective in significantly reducing future repair costs. Consult technical specialists as needed to develop a resilient Betterment alternative.

  • Is the bridge high and long enough and is the foundation type and depth adequate?
  • Is the culvert large enough to pass likely debris, and is inlet and outlet scour protection adequate?
  • Are riprap revetments sized correctly and is scour mitigated?
  • Is the slide adequately stabilized or is the realignment a sufficient distance from the failure prone area?
