Gough Creek and Clack Creek cross Day Road at approximately 1.6 km north of Highway 101. Gough Creek crosses Day Road about 210 m west of the Clack Creek crossing. The two creeks flow south and join with Roberts Creek downstream, before eventually flowing into the Strait of Georgia. The project will:
- Replace washed out culvert
- Repair shoulder erosion

Clack Creek
- Channel is about 3-5 m wide upstream and widens to a maximum 20 m width near the culvert inlet
