Grosenbacher Road South of Madrona


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.
