Rh: Mitigation Acreage, Randleman Reservoir Mitigation Sites
P_O1
We have reviewed mitigation acreage at the proposed Randleman Reservoir mitigation sites ati a
follow-up to your April 24, 1998 letter. It appears there is a discrepancy regarding ?Alowable acreage
credit. Although 81 wetland acres were projx) ed and accepted, DWQ subtracted existing wetlands
and stream acreage From the total, resulting in 60.4 acres of allowable credit. llvwever, Stream
channel was neither created nor destroyed, and should not be considered in the credit/debit equation.
Of the 18.87 acres of jurisdictional wetlands/surface waters verified by COO 6.95 acres were linear
stream systems. Therefore, 69.08 mitigation credit acres are warranted (h 1 acres - 1 1.92 acres of
existing wetlands) (sew attached table).
The Piedmont Triad Regional Water Authority is actively pursuing identification of additional sites
to complete the 120 acres of restorationkmation required by DWQ for this projuct.

We must then deduct existing Jurisdictional wetlands, as verified by COE (11,92 acres)
The linear stream acreage (6.96 acres) should not be deducted because stream channel
is neither created nor destroyed (per DWQ)
