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?
