For example, it lacks <br /> shoulders or adequate troughs to catch falling rocks and debris. The road is slippery, particularly <br /> after heavy rains, and adequate stormwater infrastructure is lacking. Some portions of the road <br /> are unpassable for two vehicles. Limited sight distance along the road hampers driver ability to <br /> safety navigate oncoming traffic and pedestrians in the roadway. <br /> WHEREAS, Waipi'o Valley Road descends about 800 feet in elevation over <br /> approximately 4100 feet. Rock outcropping and vegetation overhang the road. <br /> WHEREAS, Waipi'o Valley Road can experience significant amounts of runoff, <br /> particularly after heavy rains.
