Presentation Description

The area next to the ‘White house’ is being changed into a garden. Investigate possible designs for this space. It is on a slope so make sure your designs incorporate drainage features and ways of trapping soil. Also take into account the cost of each design. Do not forget about black rainstorm conditions!

Group 4 Project : 

Group 4 Project The area next to the ‘White house’ is being changed into a garden. Investigate possible designs for this space.

Shatin Weather : 

Shatin Weather Shatin Monthly Rainfall (mm) Maximum -662.5 Minimum -16 Average -267.125 Info from HK Observatory

Limitations of Design : 

Limitations of Design Areas around trees (immovable roots) Concrete base (limitation to depth of pipe placement) No decorative plants near the steps

Original Design : 

Original Design Brown-Steps Green Circle-Tree Green surface-Soil

Problems in the Original Design : 

Problems in the Original Design No Drainage System Soil (Infertile – from over flooding, loss of nutrients) No Water Storage System

First Design : 

First Design Yellow – Stainless Steel Mesh Brown – Soil Grey – Original Brick Barrier

Reasons for further changes : 

Reasons for further changes Lose Soil through mesh Easy Blockage of pipes from sedimentation How to hold the 2 stainless steel mesh in place How to connect the mesh with the pipe

Final Design : 

Final Design New pipe design (with holes allow water to flow through yet block out large objects. Gravel can block out surrounding soil and allow water flow No blockage, effective drainage system around the garden 4 inches diameter 7 inches deep 6 inches wide

Video of Final Design :

Role of New Plants in Final Design : 

Role of New Plants in Final Design Plants have to be: Those around the outer edge must be deep-rooted and very water-absorbent to remove collection of stagnant water in the base of the garden. Those around the French drainage pipes must be able to withstand large amounts of water being absorbed in the soil without dying.

Choices : 

Choices Aster novae-angliae (New England Aster) Detention Basin Seed Mix  Zoysia grass

Plants in Final Design : 

Plants in Final Design The Detention Basin Seed Mix is chosen because it is a mixture of different deep-rooted plants and are very attractive. It can also withstand large amounts of water. The Zoysia Grass is used because it can withstand large amounts of water and is strong enough to survive after being stepped on by the people walking on the steps.

Cost of Final Design : 

Cost of Final Design French Drains Pipes: $350 (http://www.pipestock.com/pvcu-pipe/pvcu-pipe-10-bar-metric/) Gravel: $160 (http://www.earthproducts.net/products/gravel.html) Plants Zoysia Grass Seeds: $80 - http://www.seedland.com/mm5/merchant.mvc?Screen=CTGY&Store_Code=Seedland&Category_Code=ZOY Detention Basin Mix: $100 (http://www.ohioprairienursery.com/shoppingcart/products/-Retention-Basin-Upland-Native-Seed-Mix.html) (seed prices sufficient for maintenance for 2 years)

Possible New Group 4 Project : 

Possible New Group 4 Project Environmental Friendliness. How can you use the waste plastic bottles effectively in the White House Garden as an alternative material?
