URBAN ARCHIPELAGO

HOTTER SUMMERS, INCREASED FLOODING, SCORCHED WILDLIFE, DRY PADDOCKS TOO LITTLE, TOO LATE?

URBAN ARCHIPELAGO

Cyborg Teal infrastructure + Community = Reaching Phase IV

How can integrating a cyborg blue-green infrastructure edge into a new urban public domain, increase stakeholder understanding of resilience in the bays?

“COP26

MUST BE A TURNING POINT. WE MUST ACT NOW WITH AMBITION AND SOLIDARITY TO SAFEGUARD OUR FUTURE AND SAVE HUMANITY.”

CURRENT PROJECTIONS WILL SEE TEMPERATURE INCREASE “IN EXCESS” OF 1.5C TO 2C ABOVE PRE-INDUSTRIAL LEVELS.

BETWEEN 2013 AND 2021 SEA LEVELS HAVE DOUBLED COMPARED WITH THE RISE FROM 1993 TO 2002

CURRENT SEA LEVEL RISE PROJECTIONS

as humans we have re-etched and botched this landscape

despite this, there is still hope we can achieve this through edge a BGI hybrid edge...

we need to educate people whilst creating climate resilient landscapes to help heal mother nature and the toxic sludge of industry

FINDINGS

Potential site opportunities for the sites unique condition, orientation and natural processes of the area are outlined below:

RECONNECT OPEN GREENSPACE UNLOCK FORESHORE INTERACTION

• Re-establish ecological connections

• Hybrid blue-green infrastructure elements BGI

• Reconnect community to the waterfront

• Frame the historical site views to emphasize site peninsula

ACCESSIBILITY

SENSORY

CREATE A SENSORY LANDSCAPE

• Create refuge from ultra-urban landscapes

• Habitat hybrid elements weaved into wetland corridors

IMPROVE CLIMATE RESILIENCE

• Foster an educational landscape on climate change and sea level rise

• Improve stakeholder understanding of BGI

GREEN SPACES

WHARF INTERFACE

EMBRACE EDGE CONNECTIONS

• Retain deep water docking

• Some of the last wharfage in Sydney Harbour

• Improves hybrid wetland processes

HERITAGE EDGE FLATNESS OF SITE

CELEBRATE SITE MODIFICATION

• Maintain marine architecture

• Educational opportunities

• Original headland to support urban precinct

JUXTAPOSITION OF PRE + POST INDUSTRY

• Restore site outlook, follow CPTED for eyes on the street

• Opportunity for cyborg headland park to contrast flatness

Modify Glebe Island to incorporate resilient blue-green infrastructure corridors on-site

Reconnect and establish habitat areas to disassociate from the ultra-modified industrial landscape

Follow circular design principles + provide educational opportunities for stakeholders to celebrate site elements

TO RENEW

KEY PHASE OBJECTIVES

FAILURE

TO CUT DOWN WHARF EDGE

ROADBLOCK: DEEP WHARF EDGE CONTAMINATED SOILS

SOLUTION

BEVEL INTO GLEBE ISLAND

ROADBLOCK: DEEP WHARF EDGE SOIL LEACHING

RESOLUTION

BUILD AGAINST WHARF EDGE

BENEFITS: RETAINED DEEP WHARF MOORINGS MAXIMISING GLEBE ISLAND FOOTPRINT
