Promontory Park and Canoe Cove - Schematic Design Review

Community (Survey + Consultations) Design Review Panel SAC

• Water access and watercraft storage
• Youth/school group camp program space
• Flexibility of spaces to accommodate

economic diverse population

• Recognition of First Nations
• Universal access
• Retaining industrial heritage
• Important to recognize this park space is

unusual in an urban setting. Use of the park should be prioritized above vehicular access or transit movements

• Consider that park access ofg Commissioners

Street will be in high demand

• Wherever possible, introduce less typically

urban materials and shapes – e.g., unpaved pathways.

• Find a clear balance between constructed

nature and programmed space

• Some part of the MT-35 building should be
• reconsidered. Enough of it to celebrate its

history

• Strong juxtaposition of industrial past and

landscape

• Find a role for public art within the design
• Increase porosity of park edges and

enhance park entrances

• Develop signage and wayfjnding
• Create a family of materials and furnishings
• Consider future conditions in and around

the park

• Consider experience of bridge underpasses
• Feeling immersed in nature comes from

ability to wander while discovering new views or un-manicured vegetation

• Variation of landscape and ecology was

noted as “nice to have”

• People expressed a desire for clear

information about access points (lighting and signage indicating formal paths)

• Emphasis on views and variety of

landscape types

• Create views of Inner Harbour and City
• All season use support winter programming
• Facilitate public water activities and

connections/access to the water

• Integrate history through preserving local

heritage and culture (adaptive reuse, art)
