Developing Sensitively

The Mandai rejuvenation project is being developed on impacted land which used to house villages, farms, the former Mandai Orchid Garden, as well as existing zoo facilities. Guiding this development is a carefully conceived design and construction plan to ensure sensitivity to surrounding flora and fauna.

Facilitating wildlife connectivity

Come 2019, there will be a dedicated bridge at Mandai to facilitate habitat connectivity for local wildlife in the area. The eco-link links the southern and northern sides of the Central Catchment Nature Reserve, which are separated by Mandai Lake Road, to provide safe passage for wildlife crossings. There will also be fencing around the precinct to act as a barrier to the road and guide animals towards the bridge. Besides the eco-link, trees will be planted across the precinct to provide a continual canopy connection and foliage for local wildlife movement.

Conserving and enhancing the habitat

Trees on site are surveyed and tagged based on their species, health, size and conservation status. Those of conservation interest will be incorporated into park designs or transplanted. Saplings, tree ferns and rootballs suitable for transplanting will also salvaged and relocated within the precinct. To create conducive green habitats for local wildlife, carefully curated native trees and plants will be planted as part of landscaping, while invasive species and weeds will be removed.

Special consideration for wildlife

Before the start of any construction work, great care is taken to ensure safety of wildlife through activities such as wildlife shepherding and tree inspections. Site staff are also required to undergo special biodiversity awareness training to familiarise themselves with the type of wildlife in the area and the protocol to activate specialist response to wildlife sightings.

Speed reduction measures

A series of speed reduction measures aimed at reducing wildlife road incidents has been implemented along Mandai Lake Road. This includes multiple speed humps, speed regulating strips, speed signs and speed radar panels along the road. Speed limit for most parts of the road has also been reduced to between 20 and 40km/hr. To remind drivers to slow down, there are wildlife crossing signs lining Mandai Lake Road and at carpark entrances. These measures are continually reviewed and enhanced. There is also a dedicated team that monitors wildlife road incident within and around the project area, and responds round-the-clock to such incidents. To report wildlife road incidents, please call our wildlife response hotline: 9088 5068.

Environmental Impact Assessment

In 2015, Mandai Park Holdings (MPH) gazetted the results of an Environmental Impact Assessment (EIA) for its plans to develop Mandai into an integrated nature and wildlife destination that promotes sustainability and wildlife conservation. The Mandai EIA Report was commissioned by MPH and undertaken at a conceptual design stage, prior to development work. It surveys the baseline environmental conditions within the project site and evaluates potential environmental impact of the project. The Mandai EIA Report also includes recommended mitigation measures and an Environmental Management and Monitoring Plan (EMMP), which were approved by the relevant government agencies. An Environmental Advisory Panel (EAP) provided guidance and oversight for the EMMP.

Since the publication of the Mandai EIA Report, regular discussions on environmental management have continued with various stakeholders. As far as possible, design development and construction methods were aligned with the environmental management requirements stated in the Mandai EIA Report. However, as the project progressed into the detailed design development and construction phases, some refinements and/or changes in environmental management requirements were made so as to better account for unexpected developments, practicality and feasibility.

For revisions in designs and/or changes in environmental management measures from that in the Mandai EIA Report, MPH has adhered to the required Change Management process and conducted a series of consultations with its EAP and representatives from the nature community. Thereafter, approval from the relevant government agencies are sought to formalise the changes to the Mandai EIA Report.

A summary of design updates and approved changes to requirements listed in the Mandai EIA Report can be found in the Addendum. The Addendum shall be read in conjunction with MPH’s EIA Report dated 26 September 2016 and shall form part of the Mandai EIA Report.

The Mandai EIA Report along with the Addendum, are available for reference below.
