Eco-park in Zhenjiang City

A 40-hectare parkland, designed by our landscape architects in China, will soon create a green corridor through a new satellite town being constructed east of Zhenjiang City area in China.

The Zhenjiang City local government has commissioned Boffa Miskell to carry out the park’s conceptual and detailed design, and then engage a local design company to prepare the construction drawings and supervise the construction; an arrangement that brings together local knowledge with the expertise in our Shanghai office.

The project brief for an ‘international style eco park’ bordering the new development’s main road is a challenging, though exciting, opportunity to create a vibrant linear park which will form the heart of the new town. Natural elements and processes will be restored to the site which, though farmland, has been modified over thousands of years.

Low impact storm water management “Because the site is low-lying and receives runoff from the surrounding area, water is a fundamental component of the design,” explains Chris Bentley, landscape architect and Managing Principal of Boffa Miskell’s Shanghai office. “Together with our hydrological engineering sub-consultant, Ewaters, we’ve convinced the local road engineers to allow storm water to flow into the park from the nearby roads instead of piping it underground, as currently practiced. This involves retrofitting the existing roading storm water network.”

The runoff will be treated to remove contaminants via a series of rain gardens, bio-swales and wetlands before discharge into a newly created stream, which will run the full 3.7-kilometre length of parkland. The park is also designed to reduce downstream flood risk by acting as a storm water retention basin during one-intwenty-year rainfall events.

Low impact design (LID) storm water management will slow down the rate of storm water entering streams, improve water quality and enhance biodiversity. The new stream will provide habitat for fish and other water life. Locally indigenous aquatic plants will be used in the wetland and stream environments, and predominantly native plants used throughout the park.

Open space

The 40-hectare site will comprise eight parks, separated by cross roads. Five bridges will elevate the cross roads above the parkland to ensure open space connectivity and uninterrupted stream flow.Sustainable design features will be incorporated into park facilities including green roofs, solar panels and natural ventilation in park buildings; gabions filled with recycled materials in retaining walls; and footpaths of permeable concrete and local stone construction. Activities will vary from park to park as appropriate to the type of adjacent development, which will include residential use, schools, healthcare, retail, high tech business activities and a commercial centre.

Construction of the entire park is due to begin by the end of this year and is currently scheduled for completion by May 2013.
