Document Description
The proposed modifications for River Road Dike consists of a compacted earth fill dike, approximately ¬¬-1,750 feet in length. At the south end, the dike would abut the existing raised ground of the residential tract (Tract No. 31961) in a nearly east-west direction. The dike would then turn north across a tributary drainage to Mill Creek and former dairy land and then turn west and parallel the southern edge of residential tracts (Tract No. 30905 and Tract 29997), ending just west of Port Arthur Drive (Figure 2). The existing concrete channel will be extended 532 feet to the two proposed 48" culverts. An additional proposed 230 feet concrete channel will connect to the concrete channel. The concrete channel would be constructed in the southeastern corner of the site to allow drainage into Mill Creek.
