EnviroGreen

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

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

Context Map - OPEN SPACE NETWORK

Opportunities & Constraints

-Identify opportunities for site ecological restoration

Issue:

+ Limited existing vegetation area around The White Bay, lack of green open space on the foreshore.

+ Flooding/pollution

+ Weak connection to the residential area

+Scarcity of plant communities and habitats

Opportunity:

+ Increase green space. (Replace the cement floor with lawn or wetland)

+ Increase access to connect with residential areas

+ Good water management

+ Restore the local ecological environment

Fundamental Assets

TOPOGRAPHY

Topography

CLIFFS AND STEEP TERRAIN

+ 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

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?

Fundamental Assets - SPECIES

It shows that the Balmain Peninsula and nearby areas have an amazing number of native species

Fundamental Assets - GREEN SPACE AND SPECIES

Precedents

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

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

Jeanne d'Arc Square, France - The revolving bench

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

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

Copenhagen- The forgotten giant

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

Stage Plan

Stage 1:

5 Years

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

10 Years

Stage 2:

Rebuild ecological system to realize a biodiverse rich area on this site

50 Years

Stage 3:

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

LEGEND

Landscape Layer

Stage Section

Stage 1- POLLUTION TREATMENT

Contaminated Soil Remediation

Analysis of contaminant components in soil

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

Plant volatilization

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

Gradually remove pollution through a bioremediation system.

Plant degradation

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

Existing

Purpose

Water flow directly into the ground

Water flow is buffered and fillter

Concept Model

Green Park Plants

Stage 2 - Wetland

Biological returning to the Sydney

Plant absorption

Soil adsorption

Microbial layer Store water

Drain pipe

Wetland

+ Wetland parks can provide habitats for animals and plants, and their circulatory system can consciously allow the public to interact with water bodies.

+ Wetlands help to clean the water and collect stormwate, effectively prevent flooding

Wetland Plants

Stage 2 - Green Roof

Relying on buildings to create a small ecosystem to create habitats for local insects

Vegetated Mat

Retention Fleece

Drainage/Fillter

Root Barrier

Conventional Roff Assembly

Green wall & Street Section

Establish drainage system through existing terrain, purify street water and rainwater to store

Green Wall Green Roof Main Street

Street Plants

Geen Building

Green spaces are regardless of size. In addition to parkland, residents can also create habitats for wild animals on their buildings, connect the city and nature, create new urban landscapes, and provide wildlife corridors.

5 Year

10 Years

Years

Stage 2 - LIVING SEAWALL

+ Provide shelter for marine animals and provide breeding habitat

+ Provide foraging places for fish

+ Stabilize sediments, prevent re-suspension of sediments, and improve water clarity

+ Cleaner water promotes the recovery of aquatic plants

Living Seawall 1 Year 5 Years

Stage 3 - ADD INTERACTIVE LANDSCAPE

Dancing Trees

There is a circle under each tree and a button near the circle. When the switch is activated, the tree will rotate, visitors can interact with the tree.

Seating Area

Provide visitors with a resting place and close to observe aquatic plants

Social Space

Social Space

+Provide venues for events/festivals

+Encourages the-creation and social cohesion within

Planting trees helps improve and beautify the environment and provide shadows for the public to achieve a good human user experience.

PUBLIC SPACE WITH CPTED - PREVENTION

The street section shows the distance between nature and people. Close to a good environment makes people relax
