Purpose: Restoring a terrace to reduce slop length, reduce erosion, reduce sediment content in runoff water, improve water quality, intercept and conduct surface runoff at a non-erosive velocity to a stable outlet, retain runoff for moisture conservation, or prevent gully development.
Conditions Where Practice Applies:
The existing terrace system must meet all the requirements listed to be eligible to receive state cost-share assistance.
a. The terrace system must be 20 or more years old and on
cropland only.
b. The system must have less than 50 percent of the terrace
capacity remaining, based upon cross sectional area.
c. Adequate, stable outlets must be available for each terrace.
d. Reasonable efforts must have been made to maintain the
terrace system.
e. A terrace system is defined as a single complete terrace or a
group of terraces treating a field or portion of a field.
f. The existing cross sectional area for gradient terraces has the
capacity to carry less than 50 percent of the design discharge
without overtopping or a minimum of 0.5 foot of height.
