SPECIFICATIONS
1. Ensure that the subgrade for the filter and riprap follows the required lines and grades shown
in the plans. Compact any fill required in the subgrade to the density of the surrounding
undisturbed material. Low areas in the subgrade on undisturbed soil may also be filled by
increasing the riprap thickness.
2. The riprap and filter must conform to the specified grading limits shown on the plans.
3. Filter cloth must meet design requirements and properly protected from punching or tearing
during installation. Repair any damage by removing the riprap and placing another piece of
cloth over the damaged area. All connecting joints should overlap so the top layer is above
the downstream layer a minimum of 1 foot. If the damage is extensive, replace the entire
filter cloth.
4. Riprap may be placed by equipment, but take care to avoid damaging the filter.
5. The minimum thickness of the riprap should be 1.5 times the maximum stone diameter.
6. Riprap may be field stone or rough quarry stone. It should be hard, angular, highly wether-
resistant and well graded.
7. Construct the apron on zero grade with no overfill at the end. Make the top of the riprap at
the downstream end level with the receiving area or slightly below it.
8. Ensure that the apron is properly aligned with the receiving stream and preferably straight
throughout its length. If a curve is needed to fit site conditions, place it in the upper section of
the apron.
9. Immediately after construction, stabilize all disturbed areas with vegetation.
MAINTENANCE
Inspect riprap outlet structures weekly and after significant (1/2 inch or greater) rainfall event to
see if any erosion around or below the riprap has taken place, or if stones have been dislodged.
Immediately make all needed repairs to prevent further damage.
