OakCreekRestoration

Design alternative 3 i.e. the final design was similar to design alternative 2 except the inner berm was removed and the channel bottom was flattened into a trapezoidal shape. The trapezoidal shape of the channel bottom was more consistent with the natural channel conditions of Oak Creek. The bottom of the channel was expanded 4 feet in each direction giving the channel an 8 foot width with equal elevations as the thalweg. The extra cut from the channel bed expansion was used to reduce the slope next to the campground road. The overall cut/fill was balanced near zero.
