Tree Lilac shade grove
In the northeast Roughriders Fan Plaza - the stadium main
entrance plaza - the grove of Japanese Tree Lilacs 'Ivory Silk'
(Syringa reticulata 'Ivory Silk') provides game-goers with a place
to gather that is a little cooler and more shaded than at the centre
of the plaza. Benches from the old stadium were assembled and
recreated as street furniture and installed around the sides of the
grove. The Tree Lilacs, spaced at 6m OC in each direction, are used
for their hardiness and display of white flowers in late spring (the
Roughriders colours are green and white). There are 13 trees and
13 benches and the " Thirteenth Player " is traditionally the team's
fan base.
Japanese Tree Lilacs are also installed in the smaller plaza grove at
the southwest Stadium entrance.

Tree Trenches and Beds
To ensure that urban trees grow to a reasonable size one of the
most important requirements is appropriate volume of soil for
the roots. Along Elphinstone Street and 10th Avenue extension,
the continuous tree trenches provide a shared 14.4m3 per tree
(Figures 12, 13).

Imported topsoil had been stripped from areas of residential
development in and around Regina, and stockpiled by the
contractor. Since the project is located on the former Exhibition
ground, there was no native soil on site. Soil quality was required
as a minimum to meet standard City specifications. Composted
manure was specified as an organic amendment, to provide both
volume and active biological processes to the soil.
This article looks at design of the new Mosaic Stadium landscape
from the perspective of its trees, including layout, urbanneighbourhood context, and technical requirements. As we today
benefit from the work of our forebears, the hope is that those who
follow will enjoy the benefit of our work today.

With high volume of pedestrian traffic at peak periods the tree
trenches cannot remain open: they would be subject to heavy
trampling, and possibly create a tripping hazard. A reinforced
concrete " bridge " spans the trench, anchored on either side of
the trench.

The pavement surface opening for each tree in the continuous
trench is 1.5 x 4.5m. This provides air and water exchange for the
tree roots, and access to the trench for servicing. The tree grates
were custom designed and fabricated in interchangeable sections
to support vehicle weights yet have openings narrow enough that
would not catch footwear.

Not only does it look good, it makes you feel good.
