Thirsty landscaping is an approach of design that can help to redue nd slowing down the velocity of surface water runoff. Thirsty landscaping is also an environmentally friendly approach to portrait sustainability living lifestyle. The injection of thirsty landscaping not only to help reducing or act as mitigation to solve flood issue, but it also help to inject greeneries to the study area and bring benefit to the environment.
In Sungai Pinji, Bercham, thirsty landscaping is proposed in order to overcome the physical issues on site.
It also meant to ensure improvement of stormwater management on site. The design of the linear park is to counter the flood issues and provide more greeneries to site.
This chapter will provide the detail of the design idea of proposed linear park to combat flash flood issues at Sungai Pinji, Bercham. This chapter also will introduce the design proposal which includes master plan, enlargement, perspecvtives and design guidelines.
Design Statement, Goal and Objectives
According to Sim Van der Ryn and Stuart Cowan, ecological design can be define as any form of design that minimizes environmentally impacts by integrating itself with living process.
In other word, ecological design is an interpretive way to solve the site issues with embrace the ecological impacts afterward.
The goal of the project is to create a space to counter flash flood issue by mimicking the function of a tree to increase water absorption at site. The use of greeneries to increase the environmental benefits for site.
In a simple word, to enhance the river quality of Sungai Pinji, Bercham, Perak by proposing linear park to counter the occasional flash flood due to overflow of surface water runoff through thirsty landscaping approach and providing space for local community recreational and gathering activity.
As a design-based study, there are several objectives set out to ensure a successful development of the heritage routes and waterfront park:
- To propose more pervious surface to adequate more water filtration and absorption into the soil.
- To provide enough space for local community to enjoy a healthy and safe environment that entrusted with recreational and gathering activity.
- To provide environmental benefits such as aquatic life and improved aesthetic for local community.
Based on the study from inventory, analysis and synthesis, the design strategies used is by using green infrastructure in design.
Green infrastructure is a cost-effective, resilient approach to managing wet weather impacts that provides many community benefits. Green infrastructure uses vegetation, soils, and other elements and practices to restore some of the natural processes required to manage water and create healthier urban environments. At the city or county scale, green infrastructure is a patchwork of natural areas that provides habitat, flood protection, cleaner air, and cleaner water.
Permeable pavements infiltrate, treat, and/or store rainwater where it falls. They can be made of pervious concrete, porous asphalt, or permeable interlocking pavers. This practice could be particularly cost-effective where land values are high and flooding or icing is a problem.
Urban Tree Canopy
Trees reduce and slow stormwater by intercepting precipitation in their leaves and branches. Many cities have set tree canopy goals to restore some of the benefits of trees that were lost when the areas were developed.
Bioswales are vegetated, mulched, or xeriscaped channels that provide treatment and retention as they move stormwater from one place to another. Vegetated swales slow, infiltrate, and filter stormwater flows. As linear features, they are particularly well suited to being placed along streets and parking lots.
Soil profile show the underground drainage design collect the surfacewater and flow into conventional sum and release back into the river.
The design concept for this study is based on the reference cases in Bangkok where they used rain tree as the concept. The use of rain tree as concept is to resemble the system of rain tree that live, absorb and used up the water. In order to use tree as a concept, the study should focus on the tree morphology itself.
Basically, rain tree is a distinctive tree with umbrella-shaped crown. The crown is typically broad and domed. The flower (12-25 per head) are massed in pinkish heads (5-6cm) across. The leaves are alternately arranged along the twig and have permanent swelling.
In producing the design proposal, a few steps were made in order to capture the strategic and most suitable area for being develop. Thus in order to allocate the exact area for any development this design proposal will show the site spatial programming, functional diagram and conceptual diagram.
Landscape master plans for the case study is based from the design process have been done. This Landscape master plan is the unique combination of site and program that create a unique set of location. The concept for overall masters is “Routes to Roots” and supported by the theme ‘The Authentic Pearls’.
Plan 5.7 Master Plan of proposed areaBasically there are nineteen attractions that have in the master plan based from the function and planning that have been made. The attractions are:
- Fort Cornwallis
- Penang Historical Park
- Rain Tree Food Court
- Padang Kota Lama
- City Hall
- Town Hall
- Kok Seang Tat Fountain
- Memorial To James Richardson Logan
- Dewan Sri Pinang
- Padang Kota Food Court
- Ship Tour
- Esplanade Promenade
- Cenotaph 14.Navy Museum
- Penang Yatch Club
- Swettenham Pier
- Weld Quay Waterfront
- Tanjung Marina Bay
- Pengkalan Raja Tun Uda
There were two enlargement plan derived from the masterplan. First enlargement plan focus at the linear park area and second enlargement plan focus at the community park.
