LAND2413 - Project 3

Let the tentacles of ecology reestablish themselves in the Ria, that is the city of Sydney z5203381 Peiying Chen

Principles Hybrid Question : If White bay becomes a place with rich habitats, it will provide services for creatures while providing a space to encourage the public to interact with nature for the local community?

Principle1: Restore the local ecosystem Objective 1: Rebuild habitats for animals and plants to promote the improvement of biodiversity Objective 2: use a wetland water management system to realize water circulation

Principle 2: Create a green public space and give the community new value Objective 1: Design a place that satisfies the in-depth interaction of the public Objective 2: Enhancing the accessibility of the venue

Opportunities & Constraints -Identify opportunities for site ecological restoration

Issue:

The direction of water flow

Opportunity:

+ Limited existing vegetation area around

+ Increase green space. (Replace the cement

The White Bay, lack of green open space on

floor with lawn or wetland)

the foreshore.

+ Increase access to connect with residential

+ Flooding/pollution

areas

+ Weak connection to the residential area

+ Good water management

+Scarcity of plant communities and habitats

+ Restore the local ecological environment

Base map by Pei, edit by Author (2021,T1,Group work )

+ The residential area in the north and west is separated by cliff and retaining wall of White Bay and Glebe Island. + An opportunity for the design of water system.

Fundamental Assets HYDROLOGY AND TIDE - Flooding Issue

+ The low permeability of the hard surface of the cement floor built by reclamation is the direct cause of flooding. Due to the lack of green space, rainwater runoff is not filtered, and heavy metal substances in the original soil will flow into the sea together, causing marine pollution. + Sea-level rise +Find a way to solve the problems of flooding and pollution caused by rainwater runoff, such as wetlands, rain gardens

Current Highest Tide

2100 Highest Tide

Fundamental Assets RECLAMATION AND SOIL POLLUTION + Due to large-scale urbanization, the coastline in 1788 has undergone major changes over time. + Past industrial activities have polluted the environment, and the ecosystem has been destroyed +How to use the landscape to alleviate the long-term pollution of the shoreline?

Precedents -Explore the level of interaction through different types of interactive landscapes.

Sydney Light Art Festival-Aqueous

Liverpool, England-Dancing Trees

As participants walk and stroll along the aisle, colours and light will interact with participants.

When the switch is activated, the tree will rotate. Visitors can interact with the trees.

Jeanne d'Arc Square, France - The revolving bench

Copenhagen- The forgotten giant

The revolving bench changes the rules and regulations of the venue, and change the space according to the needs.

Made from discarded wood and fallen trees in the forest. They have different shapes and are hidden in different places

Stage Plan

5 Years

Stage 1: Governance of water pollution, improve the soil environment and establish landscape types

Stage 2: Rebuild ecological system to realize a biodiverse rich area on this site 10 Years

50 Years

Stage 3: Add interactive landscape, let the people and nature coexist harmoniously, and give the community new value

Stage 1- POLLUTION TREATMENT Contaminated Soil Remediation

Analysis of contaminant components in soil

Plant volatilization

Introduce decomposing enzymes and other organic materials to achieve the purpose of decomposing pollutants

Plant degradation

Gradually remove pollution through a bioremediation system.

Add microorganisms to the soil to digest accumulated heavy metal pollutants.

Rhizosphere degradation

Build a new ecosystem on the original cement surface + Using the landscape to intervene in concrete land, treatment of pollution, rebuild ecosystem, and regenerate biodiversity

Stage 2 - IMPROVE AND INCREASE HABITAT

+ Increased habitat + Connect the residential area on the cliff with the that the terrain has site through a rampway, enhanced accessibility View
