It ranges in width from 21 feet near the channel crossing, to 26 feet in other areas, and is about 1.5 miles long. The Project includes Shadow Court and Sandpiper Lane. The street consists of three distinct sections. The southern section is straight and wider. It has undeveloped property, a park, and a school yard fronting on it. It has a rural cross - section; however some of the ditches are gone. The middle section is narrow and has wetlands and the channel abutting it. Soil borings show the underlying soils are poor and contain 15 -foot to 20 -foot deep sections of peat where the street crosses the channel. The road elevation near the channel is low, and the lake has overtopped the road in some years. It has a rural cross - section which is elevated from the surrounding land. Drainage is undefined in this area. There are many trees close to the street in this area. The northern section is residential and the street there is narrow. The street was initially a rural section street with ditches handling the drainage. Over the years many of the ditches have been filled to create front lawn areas. Because of the flat street grades in many areas, this filling has created drainage problems such as icing in the winter and standing water in the summer. The sandy nature of the soils has mitigated this problem somewhat. Currently, the street is not centered within the right -of -way, but rather meanders within it. Shadow Court and Sandpiper Lane are wider streets with bituminous curb. These streets have good grades, and drain towards West Shadow Lake Drive. Page 3 13849.005 • •
