Challenge

A major factor in realizing City of Sunderland's vision for a revitalized city centre was the City’s
acquisition in 2011 of the old Vaux brewery site that had been unused for the previous decade and was now primed for redevelopment as a new business district. Central to this redevelopment project was the realignment of St. Mary’s Way, a 500m portion of the city's central ring road.

Trees would play a significant role in the redevelopment aspirations of Sunderland, and especially on the site of St. Mary’s Way on the ring road. The Sunderland Central Area urban design strategy document states that “tree planting should be a priority along the ring road as part of its transformation into a ‘Great Street.’”

Large specimen trees would help to att ract businesses as much as pedestrians to the new development and gateway. The City Council wanted to plant the trees near the roadways and ensure their prosperity for future generati ons, having a goal for the tree planti ng scheme to be successful for at least fifty years

Solution

Silva Cells were specifi ed for the project in order to meet these needs. James Gordon, Senior Landscape Architect for the Sunderland City Council, instrumental in the decision to bring the Silva Cell system into the project said: “To assist us in delivering a new road realignment through Sunderland City Centre, DeepRoot played a key role in transforming the character of the highway network into a traditional tree lined avanue, allowing us to plant large specimen trees under footways and in close proximity to the road."

The fl exibility of the Silva Cell system also permitt ed Gordon and the design team to workwith the existi ng utlities and other features of the site while sti ll providing adequate void space beneath the road to give the trees access to the nutrients required for a long life. Gordon explains: “In maximising the soil volume per tree whist providing suitable load bearing capacity, we are confi dent that we are giving th trees the best possible chance to thrive in this urban environment. DeepRoot’s design service allowed us to overcome complex constraints such as existi ng utilities, new surface water drainage systems and dealing with trees on such a large scale.

Altogether, 1,772 frames and 866 decks were installed in a two layer system along the boulevard, bringing 16.18m3 of soil volume to each of the 31 newly planted trees.
