Embankment protection is required from the toe of the highway embankment up to an elevation equal to the conservation pool elevation, plus the effects of wind tide and wave runup.

Where the toe of the roadway embankment is below the conservation pool elevation, the minimum elevation of the top of the protection should not be less than 3-feet above the conservation pool elevation. The remaining embankment above the limits of the required protection is an area of lower risk of damage from wind effects than the area affected by wind on the conservation pool. Generally, a vegetative cover with a strong root system is adequate and very economical.
