I I. Drainage Provisions I The drainage provisions for a roadway are either designated as urban or rural. An urban section has curb and gutter and storm drainage pipes to convey the water to an outlet pond or receiving water I body. In a rural section the water runs off the roadway into ditches which convey the water. Highway 96 is mainly "rura]" in design. The main problem with the current rural drainage design on Highway 96 is that many of the ditches are overgrown with vegetation and many of the culverts I under driveways are plugged. This causes standing water which undermines the stabality of the roadway and can cause localized flooding problems. I Clear Zone and Roadside Obstacles The "clear zone" is the distance from the edge of the traveled lane that should be free of any non- . traversable hazard or fixed object in order to provide an area free of obstacles for a vehicle to recover if it runs off the road. On a rural roadway with 3: I slopes, a clear zone of 53 feet would be required for a design speed of 50 miles per hour. This distance is increased if the roadway is on a curve. I Numerous roadside obstacles inluding utility poles, trees, ditches, and ponds exist along highway 96 within the "clear zone". . Turnin~ Provisions .e There are numerous access points along Highway 96 where vehicles make turns from the highway. In many locations there are no turn lanes and these turns (both left-turns and right-turns) are made from the through lanes on Highway 96. This creates a safety problem as well as reducing capacity I on the highway when vehicles slow or stop in the through lanes in order to make their turn. Pavement Condition . The road surface on many segments of Highway 96 is in poor condition and needs to be replaced. The poor pavement condition affects safety, driver comfort, wear and tear on vehicles, and long term . maintenance costs. An overlay can provide a temporary fix. However, the tumback funds provide the County with an opportunity to provide a longer term solution and reduce,future maintenance costs. I Pedestrian Provisions .
