The do issues of significance with regard to the review cf this project are 1) the integrity of the rock placement, and 2) the ability to revegetate the slope. Two other bank restoration projects similar in design have been constructed by Mr. Niccum, the contractor. The first project for Ms. Haverstock, at 3350 North - home RD., Deephaven, used 792 tons of Class IV & V rock on the face with Class I & II rock as fill. The placement extended 16' waterward of the NOHW and the rock is 11' deep in the center. The face slope of the rock is 2:i, with the sides approaching a 1 1/2:1 slope. The vegetation being established is Polygonum, or commonly refered to as Fleeceflower. The second restoration project for Michael Sill and Ray Mithun, at 3610 North - home RD, Deephaven, used 576 tons c,f Class IV & V rock on the face with C1assI & II rock as fill. The placement extended 6' waterward of the NOHW and the rock is 14' deep in the center. The face slope of the rock is 1 1/2:1. The voids in the rock have been filled with dirt to encourage natural vegetation regrowth. Both of these projects were reviewed and approved as After -the -Fact. applications by the Minnehaha Creek WSD as acceptable for design integrity and construction methods for projects of this type.
