The purpose of this chapter is to provide standards for the construction or reconstruction of roads. These standards are for roads in low to medium density residential and light commercial areas. A large scale development study will be required for any development that generates sufficient traffic to necessitate additional construction requirements. (Ord. 2000-02, 3-3-2000)

Any requirement of this chapter may be altered as a result of a large scale development study required by this title. (Ord. 2000-02, 3-3-2000)

All culverts and bridges shall be designed by a professional engineer. Bridges and culverts are subject to the stream corridor and floodplain requirements of this title.

1. All bridges and culverts on natural watercourses shall be designed to pass a 100-year flood without damage to the bridge or its approaches, without diverting floodwaters onto neighboring properties, and without increasing the level of the base flood downstream.
2. The developer may be required to install a bridge rather than a culvert on any natural watercourse where such action is required, on the advice of the Idaho fish and game department, to protect the fishery.
3. Culverts not included in Paragraph A of this section shall be designed to pass the runoff from the 10-year, 6-hour storm.
4. All culverts and bridges shall be designed to support a minimum gross vehicle load of forty thousand (40,000) pounds.
5. There shall be a minimum fifty foot (50') straight on approach to all bridges. (Ord. 2000-02, 3-3-2000)
