§ 24.30.130. Wetlands—Bridge and culvert replacement.

Replacement of a bridge or culvert is allowed if necessary to conform to current standards or as part of a development approved consistent with this chapter, if:

A.

The existing bridge or culvert was lawfully established;

B.

There is not another alternative available that has less adverse impact on the wetland and buffer and any associated stream/riparian habitat area (see TCC 24.25.130);

C.

The bridge or culvert is designed to avoid or, where that is not possible, minimize impacts to the wetland and any associated stream/riparian habitat area, and it is in compliance, to the greatest extent possible, with TCC 24.30.280 below (in the case of culverts in a Type F or S stream see TCC 24.25.130);

D.

In the case of culverts in wetlands associated with a Type F or S stream, the culvert is made passable for fish in accordance with the WDFW Fish Passage Design at Road Culverts, 2003, as amended, and the National Marine Fisheries Service Guidelines for Salmonid Passage at Stream Crossings, 2000, as amended;

E.

If the culvert involves a ditch, the ditch is not increased in width at the culvert site unless it is narrower at that point than the rest of the ditch and would otherwise impede the flow of water. In that case, it may be widened to the minimum extent the approval authority deems necessary; and

F.

Flood hazards are avoided and the proposal is consistent with Chapter 24.20 TCC and other applicable regulations.
