Grants administered by the Erie County Conservation
District are available on a competitive basis to Townships to mitigate
erosion and sedimentation problems of dirt and gravel roads. The
Commonwealth provides funding for this program to all Pennsylvania
Counties. This year's mitigation project was selected
because the ditch pictured below suffered from high-water-flow erosion
that ejected the eroded sediment directly into Goodban Run, a tributary of
Little Elk Creek.
The remediation process begins with removal of native
ditch materials and enlargement of the ditch profile to accommodate the
placement of a layer of erosion control geotextile fabric under R-5 rock.
R-5 rock are 12-inch to 18-inch angular-faced limestone crushed rock that
will remain in place as a ditch lining even when the ditch is flowing full
with water.
Besides stopping the erosion of the ditch, the rock
lining provides the additional benefit of trapping sediment migrating from
upstream.
The budgeted expenses for this project are:
$5,100 grant from the Dirt & Gravel Road Fund
$7,100 in-kind contribution of labor and equipment
by Franklin Twp.
