Put alternative text to describe image in info box

Heavy rains caused debris blockages and washed out culverts at Kenyon Creek, located just east of Sargeant Bay Provincial Park, running about 2.4 km from north to south on the Sunshine Coast of British Columbia.

Last Updated: September 22, 2023

The creek is adjacent to Highway 101 along its north half, and crosses Redrooffs Road at approximately 55 m elevation. The project will:

  • Replace washed out culvert
  • Repair shoulder erosion

Conditions

Redrooffs Road

  • One travel lane in each direction and is approximately 6.5 m wide at the Kenyon Creek crossing
  • The road embankment at the culvert outlet slopes down at approximately 1:1 (H:V) to the bottom of the channel

Kenyon Creek

  • Flows across Redrooffs Road from north to south before eventually reaching Sargeant Bay about 500 m downstream of the crossing
  • Channel has a bottom width of 4 to 6 m and a bank full width of 10 to 15 m
  • Short section of channel at the culvert inlet which a waterfall flows into
  • The upstream area of the waterfall contains naturally fallen woody debris
