Bukit Batok N3	Bukit Batok N3 has largely been zoned for residential development in URA's Master Plan since 2014, and is currently occupied by various interim uses which will be phased out progressively when their leases expire. Agencies have plans to redevelop this site to offer more housing choices in the west region of Singapore. An Environmental Impact Assessment (EIA) was conducted for a portion of the site that is currently used by HomeTeamNS Adventure Centre for recreational activities, to guide the development plans for the area. Based on the EIA findings, a proposed retained area (PRA) has been identified as a stepping stone for fauna in the area to move between Tengah Forest and the wider Bukit Batok Nature Corridor. In addition, agencies are proposing various measures to ensure there is ecological connectivity in the area, including a 3m to 5m wide planting strip along the roads, and a linear green through the developments for fauna to move between Tengah and Bukit Gombak Park. HDB has engaged biodiversity experts and Nature Group representatives to seek ideas and feedback on our plans, to develop the site sensitively.

Yishun Chencharu (Site 2)	Chencharu has been occupied for various brownfield uses such as farms and plantations since the late 1800s and has been zoned for residential use in URA's Master Plan since 2019. In March 2024, Chencharu was announced as a new housing area in Yishun Town with new amenities for existing and future residents. The first BTO project (Chencharu Hills) was launched for sale in June 2024, and agencies are currently studying detailed plans for later phases of Chencharu south of Yishun Walk. An Environmental Impact Assessment (EIA) was carried out in 2024 to assess the environmental impact of proposed diversion works for an existing earth drain located in the later phases of Chencharu. The earth drain was constructed in the 1980s to drain discharge from surrounding low-rise agricultural uses, and drain diversion works would need to be carried out to serve drainage needs of upcoming developments. The study found that the earth drain was of low ecological value with no aquatic species of conservation significance recorded, and the habitat conditions were not pristine. Through our engagements with biodiversity experts and Nature Groups, HDB has proposed various mitigation measures such as relocating existing fauna before any works commence and implementing safeguards to avoid any impact to the water quality. In addition, biophilic features will be planned within the new development to attract local biodiversity into the area.
