As part of the Meadow Way bridge replacement project, the design team made changes to the retaining wall in the creek at the base of the 333 Cascade Drive property (Davis-Thompson family). The change was made to break up the long wall for better aesthetics, add more visible green space, and take advantage of an opportunity to extend the fish habitat.

We have also posted additional materials and literature for your information on the project website. Please check out this update after taking this survey.

We want to hear from you! Please review the latest retaining wall designs for Meadow Way, and let us know what you think. The survey will close Jan. 5, 2018.

Design Details

What stays the same:
  • One portion of the retaining wall is still connected to the bridge at the slope base/creek bed level.
  • Wall surfaces will be treated architecturally.
  • The slope will be planted with native riparian trees, shrubs, and vines.
  • Fish habitat will be preserved at the base of the wall.

What’s new:
  • The new retaining wall comes in two segments, with a separate upper level retaining wall where the current property’s redwood fence is; this wall will be under a new redwood fence, similar to what is there now.
  • There will be a specially designed log-rootwad revetment at the base of the slope to expand the fish habitat beyond the lower retaining wall. This revetment is made up of a grid of fairly large logs, with their original root balls, placed at the creek level to protrude a little bit outside the toe of the slope that will be built over it. The grid is then filled in with large boulders and topped with soil and smaller boulders to create a stable slope to the top where the upper wall will be. At the base, and in front of the boulders, a natural pool is created in the creek and the logs and slope are seeded with willows and other native trees and plants to create shade over the pool and nooks and crannies, which the fish like and find inviting. (See photos here and online.)
  • There will be an informal footpath from the top to the creek, which will not be designated as an official path, but will not preclude walking down to the creek.
