Re-PARK ing Ames, Iowa, USA >> Fall 2015 Individual work

Description In Aug year 2010, the whole parking lot area had immersed with water by 14 inches of rain in 4 days.

A 2.9-acre commuter lot adjacent to Squaw Creek is transformed by the precise, focused introduction of manufactured soils, permeable paving, riparian trees and wet meadow plants, reducing stormwater runoff and pollutant loads that cause flooding and impair water quality.

This wasteland becomes a civic green space, further transformed by the introduction of seating, tables and human scale vine scrims that re-scale the vast space into welcoming pockets of social space where friends can meet and hang out.

Site profile Jack Trice Stadium_Iowa State University_USA coordinate_42.017479, -93.636734 2.9 acres Reviewing the approaches for linking tre based stormwater systems, the project applied the strategies according to EPA publication Storm to Street Trees.

Interception by mature trees is significant, water redirected into plant and soil systems reduced parts of the runoff.

In addition, according to Phyto: Principles and Resources for Site Remediation and Landscape Design by N Kirkwood & K Kennen, phytotechnologies in vegetation is a potential use to remediate and remove contaminants in soil and water.

Calculation 1. Amount water that generated in 14 inch storm over 4 days (14/4=3.5) from paved areas.

77693 ft (Total impervious area) x 3.5/12’ water =22669 cu ft (169579.34 gallon)

2. Daily Water interception by trees 15% of CPA x(3.14x45²) x 0.29 = 276 cu ft (per tree) ( 2069.12gallon) 47 trees =13000 cu ft (97246.75 gallon)

3. How much runoff could be retained(held at field capacity) in the sandy loam soil?

(Total soil volume in Silva cell) (92%x48265cu ft) x 12% water @ field capacity =5177.48 cu ft (38730.24 gallon)

4.How much could be detained (held between saturation)?

(Total soil volume in Silva cell) (92%x48265cu ft) x ( 45% Saturation- 12% Field capacity) =14653 cu ft (109613.9 gallon)

5. In total, how much runoff would be eliminated ?

13000 cu ft (tree) + 14653 cu ft (detained) =27653 cu ft (206860.65gallon) Total volume of rain =22669 cu ft (169579.34 gallon) 27653 cu ft - 22669 cu ft = (-)4984 cu ft (-37281.31gallon)

Green Roof Advanced Plant Technologies Class Lab >> Fall 2015 Individual work

This project is to design a 90 x 45 rooftop garden on 5th floor. At 15ft intervals columns are located at the structure. Each columns can hold a 450lb load. The beam hold less-at midpoint between estimate the structure will hold 130lb. My intention was to design a roof top garden with a bar and meadow garden.

By transforming the flower into geometric pattern, act as the paving and plant arrangement pattern. By locating this huge pattern on the ground, the meadow area become the central attraction point. Other program that happen around the rooftop would be gathering space,bar and seating for view-looking.

The plant selection partly would be herb, taking considered that the herb could use for preparing drinks at the bar, promoting a concept of consuming healthy food. It also demonstrate a link between plants and human, showing all the good benefits of plant: healing effect, enhance ecosystem, provide healthy food, etc.

Tree load calculation River Birch (Betula nigra) USDA hardiness zones: 4 through 9A Height: 40 to 50 feet, Spread: 25 to 35 Full sun is best, and being multi-branched helps it handle wind well.

Small leaves offer dappled shade and turn golden yellow in autumn.

1.Estimate the rootball diameter.

2.5” caliper tree has a 2.5’ diameter rootball 2. Estimate the rootball depth root ball depth =24” =2’ (It’s a small tree so I reduce 0.5” depth to reduce the weight)

3. Determine the tree pit width and depth.

Tree pit width should be 2’ larger on each side than the root ball diameter, tree pit depth should be 1’ deeper than the rootball to accomodate the stone layer and sand setting bed.

Tree Pit Width = 2.5’( root ball diameter) +2’ +2’= 6.5’ Tree Pit Depth= 1.5’(root ball depth) + 1’= 2.5’

4. Calculate the soil weight(including root ball) in the tree pit.

Soil weight in tree pit= soil density x tree pit width x width x depth =120 pcf x 6.5’ x 6.5’ x 2.5’ =12.675 kips 5. Calculate the total tree design load Total tree design load= soil weight( including root ball) in tree pit + mature tree green weight.

=12.675 kips + 6 kips =18.675kips 18.675 kips/ (tree pit plan area)= 18675/ (6.5’ x 6.5’) = 442 psf

G-Brick Sustainable Design Studio >> Spring 2016 Individual work > Creative component

Description G brick is a sustainable, vegetated brick designed to fit into recycling system. The adoption of G brick is hope to use in temporary disaster relief shelter or landscape structure. It only requires 4-5 days to build, local source, and 100% biodegradable. When people move out from the shelter, the abandoned houses will slowly establish into a vegetated forest.

Risk to Opportunity Sustainable Design Studio >> Xi’an, China >> Spring 2016 Group work >> Amritha Rajan, Malak Orra, Shruti Venkat, Zhe Ying Ng

Description Xi’an, the capital of Shaanxi province was suffering from the highest water risk of flooding and drought. The historical city situated by Yellow river, the second largest river in China. It constitutes the eastern terminal of the silk route and it is also known as the cradle of the Chinese civilization.

Industrial waste High Medium Low

Xi’an was densely populated due to urbanization.

Three aspects were found to be very significant to this research : FLOOD RISK AND SEDIMENTATION INFRASTRUCTURE INDUSTRIAL WASTE

Phase 1 Provide access to good quality water by localizing water collection and filtration

Phase 2 Expand the collection and filtration of water.

Phase 3 A constructed wetland integrating with a park system and water retention basin.

Phase 1- Rain garden courtyard

Rain garden courtyard

Retrofitting structural soil, cistern, water recycling system into traditional Chinese courtyard

As Xi’an is a ancient city, 40% of the traditional courtyard houses were still remained. Transforming courtyard spaces into rain garden, retrofitting it the cultural context with the advanced in plant technologies.

Introducing Silva Cell manufacturer will minimize the compaction of the soil, the engineered structural soil and plants together will reduce the stormwater runoff, also enhancing the quality of water.

The installation of water pump will capture the rainwater from the roof, storing them into a cistern, used for watering plants and other purposes. This solution help to reduce the water bill through rainwater reuse and recycling.

Phase 2-Waste & Stormwater infrastructure

Proposing toilets that work with bioswales at new transportation hubs and new housing development. The wastewater channel will be separated from the existing sewage treatment tank, and will be connected to a separate treatment tank.

Also, proposing compost toilet system close to the agricultural fields. The solid wastes and liquid wastes are separated and both used as fertilizers. This can reduce the amount of pollutants being discharged into the river.

Compost toilet

Phase 3-Wetland park & Retention pond

Stream bank stabilization

Design a wetland system in and along the river that ties to the infrastructure proposed in Phase 1 and 2. The agricultural waste will go into the retention basin before going into the river. The wetlands are existing and are being developed to serve its function of remediation, sediment control thereby controlling flood and drought.

To control the sedimentation, the river had been widen and deepen by using river bank stabilization. The bioengineering method uses logs, roots and other living plants to protect the natural river bank.

Increased sedimentation causing flood and drought.

Low ground water quality and polluted aquifers

Flooding and drought affecting daily life.

Polluted water from the river used daily High water storage implies less water flow reducing flooding.

Uses courtyards and rain gardens to store and filter waste water in households reducing ground water stress.

Incorporating bioswales within the city to channel water into the ground, reducing risk of flood and drought.

Uses compost toilets to reduce the water pollution, turning waste into fertilizer for agriculture purpose.

Incorporating wetlands and park systems to provide much needed green space.

Urban Design & Planning for Xi’an in Overall

Decreasing sedimentation in the river, thereby reducing risk of flood and drought.
