T
hese natural
features add spatial
definition and a
sense of place. Criss
crossing through the
greenspace, gravel
pathways connect people
to shaded seating areas that
provide sheltered work spaces.
Alternatively, the open grass
areas brings flexibility, acting as
an amphitheatre for company
events or simply as a space to
lay out a picnic blanket.
Native and adapted grasses,
shrubs, and vines — about 20
different species — celebrate
the diversity of the California
18 Landscape & Urban Design
landscape and reduce
irrigation needs. Particular
plant varieties, including Cape
Reed and Feather Reed Grass,
attract beneficial insects and
birds while providing food and
habitat.
Where irrigation is necessary,
reclaimed water is used
exclusively resulting in no
impact on potable water
supplies with the exception
of the vegetable garden.
The rooftop also contributes
significantly to improved
stormwater management and
reductions to the heat island
effect.
