Introduction

 

The Holland Marsh Drainage Canal Improvement Project is a plan to restructure 28 km of the canal, including total or partial canal relocation, bottom cleanouts, and additional guard rails installed in select areas.  Issues of safety, especially with respect to human fatalities and flooding, have been the primary motivations for the approximately $25 million project.

Trial Work

 

Two trial areas were undertaken from October through to December 2008 to
test construction methodologies and to assist in arriving at the true cost of
construction for the Project.

It was also necessary to achieve accurate timing windows for the various stages
of construction.

 

Interval 1

    • 350 metre length of canal was reconstructed in this area
    • clay cofferdam were placed at both end of the excavation area
    • prior to excavation the lands to be used for the relocation
    • were cleared by a combination of mulching and felling of trees
    • Notches were left on the north end to allow for continuous flow
    • Excavated materials were placed as back fill in the existing canal

Interval 15

    • 200 metre length of canal was reconstructed in this area
    • the existing canal was coffer dammed by earth at one end and rock at the other
    • prior to excavation the lands to be used for the relocation were cleared by a combination of mulching and felling of trees
    • Notches were left on either side of the coffer dams to allow for continuous flow in the canal
    • Excavated materials were placed as back fill in the existing canal
