Grosenbacher Road South of Madrona

Scope

This project consists of improvements to two low water crossings along Grosenbacher Road. The existing drainage culvert south of Madrona appears to be able to handle the current stormwater flows; however, the existing channel downstream of this culvert may need to be improved to alleviate flooding of downstream residences. The existing drainage culvert north of Madrona is of inadequate size and will need to be increased, and the existing drainage channel may need to be improved to alleviate flooding of upstream and downstream residences.
