The design is based on the study and criticism on the existing design on the site, where the water infrastructure takes 8.2% of the total area and provide poor landscape experience because of its single-functionality.

The site is organized along a triangularly intersecting road system. The gaps created by the inparallel framework function as the storm water retention areas. Programs and amenities are integrated into the water infrastructure as triggers to foster social interaction.

The framework creates a clear pattern to allocation of buildings, programs and circulations that maximize social contact. The well integrated linear slabs to elevate the houses are economic in construction, and they also function efficiently to organize watersheds.

PRE-DEVELOPMENT CONDITIONS
WATERSHED ORGANIZATION The watersheds are develope according to thte framework
WATER STOPRAGE The water storage capacity is designed for a ten-yeat storm
STEPPING STRATEGY steps are designed for one-year and ten-year storm
PIPING & OVERFLOW Drainage and overflow pipes connect the watershed allowing the site function as a system
Each watershed is design according to the storm water calculation, based on normal rain and the 10-year storm. The first terrace, the second terrace and underground pipe system work together to achieve the function of detaining, cleansing and draining.
S T E P P I N G S T R AT E GY
Through the terraced design, we shrink the inaccessible detaining area from 8.2% to 5.5%, and the storm water are slowed down and cleansed before drained into the municipal system.

FINAL DESIGN
A non-linear workflow between site design and hydrologic modeling (PCSWMM) is set up to provide solutions to the iterative design process in landscape architecture. The workflow allows designers to generate water-capable, aesthetic-pleasing and socially feasible design solutions.

Modeling outcomes demonstrate the function of the stormwater system during a ten-year storm time sequence, compared to the same design without Low Impact Development (LID). The hydrograph has significant reduction in initial flow and peak flow, which meets the design purpose.

The quantitative description of each watersheds allows further manipulation with pipe routing to optimize the dimensions, thus the site works as a system with the best spatial quality and water capacity that it can provide.

Programs are introduced to the spaces which are redeemed from the infrastructural use. By strategic placing of constructions for defined and flexible uses, the residents will have better social interaction that vitalized the community.

Three typical sections are designed in the subdivision, regarding the relationship between house to house and house to street. The typical sections fosters various informal social interactions that build a better community.
