Front Street Slope Stabilization/Reconstruction

Share on Facebook Share on Twitter Share on Linkedin Email this link
Front Street is a residential road located on the north side of the former Lake Erie bluff slope in Port Stanley.  The Lake Erie bluff slope is currently experiencing erosion and movements which are encroaching towards Front Street.  Steel gravity bin-type retaining walls were installed in the 1970’s and 80’s near the top of the slope along several sections of Front Street to stabilize sections of the top of slope and to protect the street.  These gravity bin-walls have performed successfully over several decades.  Rehabilitation of the unprotected areas experiencing movements at the top of the slope, which may compromise the municipal road (Front Street), are to be addressed.

The Municipality of Central Elgin has retained Golder Associates Ltd. to complete a geotechnical exploration and testing program for the slope and existing gravity bin retaining walls.  In July 2018, the Final Report “Geotechnical Exploration – Front Street Slope Stability Review, Port Stanley, Municipality of Central Elgin, Ontario” was provided to the Municipality.  

In September 2019, the Municipality contracted with IBI Group Inc. to complete a Schedule B Environmental Assessment of the project and provide engineering design, cost estimate, contract documentation, and drawings for the project by September 2020.

The scope of the reconstruction project will include new gravity type bin retaining walls with subdrain, curb & gutter, asphalt road and granular structure renewal, new catch basins, new storm sewer, and drainage adjustments for the existing gravity type bin-walls.  Sanitary Sewers and watermains in the area do not require replacement.   

Local traffic accommodation, emergency service access, and other related services access (school bus, garbage pickup) is paramount and shall be thoroughly considered during the design for construction.

    Will the project include an extension of the existing sidewalk at the east end of Front Street to the west end.

    Ted Halwa Asked 3 months ago

    The street design has not yet been finalized. However, in the interest of maintaining current driveway lengths, on street parking, and avoiding placing the south side curb any closer to the top of slope, a sidewalk extension to the west may not be possible.

    Can you foresee the possibility of any negative effects of the project on property below Front St., specifically West Edith Cavell Blvd?

    George Wilkinson Asked 5 months ago

    The slope stability project on Front Street is intended to stabilize movement of the top portion of the slope and protect movement of Front Street. The stability work will extend to the west end of Front Street which will cover West Edith Cavell from the community mail box to the turning circle. The stability work includes extending the gravity bin walls that currently exist on Front Street. The gravity bin walls maintain the stability of the area above – namely the road. There will be additional overland storm flow drainage collection systems constructed to restrict storm flows from being directed down the slope. This will help to stabilize the slope as well.  This new storm drainage system will need to outlet below which may require work on West Edith Cavell Blvd. The out-letting will not be allowed to flow openly onto West Edith Cavell but instead be captured in an infiltration gallery. The properties on Edith Cavell should not have any negative effects specifically with the storm water being directed down that way. All elements of the project are currently in the conceptual design stage.

    Will the road be made wider? Will there be new guard rails installed as well?

    Michel Asked 6 months ago

    • The preliminary road width expectation is to be a consistent 8m width from curb to curb.  
    • The guard rail materials have not yet been discussed and will be based on vehicular safety requirements and budget.
