The City of Hamilton’s waterfront redevelopment positions the community to meet its cultural and recreational goals of the growing city. Over the last three decades, investments helped to transform this area into a highly desirable public space for people to live, work, and play. The redevelopment of the City’s Pier 7 shoreline represents another key project that continues the revitalization of the extensive waterfront lands.
The existing shoreline edge was limited and unsafe for pedestrian access to the water. The demand for the water’s edge experience often created conflicts between casual visitors, recreational users, fishermen, and the programmed facilities provided by the Hamilton Waterfront Trust. Dillon’s team designed shore protection structures that accommodated the City’s redevelopment plans and provided unique landscaping features within the property limits and around existing underground utilities. Developing adjacent to the waterfront required a design that protect against erosion and flooding while minimizing impact on aquatic habitat.
The shore protection design included cantilever, anchored and caisson steel sheet pile structures. Cantilever steel sheet pile walls were designed for those areas where the under ground utilities were in close proximity and where the wall was fronted by a slope rock revetment. Anchored walls were designed where there was sufficient property to accommodate the anchor. Caisson were used where the water depth was too deep for a cantilever and there was insufficient property to accommodate an anchored wall. All shore structures were designed for a 50-year design life. The boardwalk boasts an extensive amount of raised seat walls with smooth cap edges wide enough for seating to ensure users have a comfortable experience. Wherever possible railings have been eliminated to allow for unobstructed view and access to the water providing anglers with numerous opportunities to cast their lines along the expanse of boardwalk. Pathways are wide enough to accommodate a diverse combination of activities.
The construction process did not negatively impact the daily use of the multi-purpose trail, the access to the marinas or other critical facilities on the waterfront. Construction was completed early in 2016 to avoid schedule conflicts with summertime events, and minimize the impact to aquatic habitat.
This project was recognized with a 2017 Project of the Year Award in the Waterfront Redevelopment Category by the Hamilton/Halton Engineering Week Committee.
