From Executive Summary on the HDB website
The Housing and Development Board (HDB) intends to undertake land reclamation at the southern region of Singapore. The City Terminals—Keppel, Tanjong Pagar and Brani—are expected to be relocated to Tuas Port by end of 2027 and the proposed land reclamation will be carried out at the vacated Keppel and Tanjong Pagar terminals connecting the area with Marina Bay to support the area’s overall redevelopment and coastal protection plans. This Project will be part of the Greater Southern Waterfront which extends from Pasir Panjang to Marina East which will be transformed for urban living along the southern coast.
The Project will comprise the construction of seawall (sloping seawall including revetments) and other marine and drainage facilities, including but not limited to soil improvement works, dredging of seabed, infilling of sand and/or other reclamation fill materials such as land-based excavated earth materials generated from the construction industry or dredged materials.
Construction activities for the Project are not confirmed at this stage but are likely to include sand key dredging and infilling, sand bund construction, seawall removal, demolition of existing piles and pile deck, and other drainage facilities within the Project site. As the construction methodology has not been firmed up, the worst-case scenarios in terms of potential impacts were identified and assessed within the study.
The following changes and impacts were predicted for the construction (process) phase:
Marine ecology and biodiversity: Increased SSC and sedimentation during construction are predicted to have up to a Minor Negative Impact on coral and seagrass at the nearby Sentosa shoreline and Marina South due to construction works and sediment transport, with Slight Negative or No Impact predicted at other receptors. Slight Negative Impacts are associated with construction disturbances (underwater noise and vibration, physical disturbances and light pollution) and deterioration of environmental quality during the construction, while the change in risk of oil spills due to vessel collisions is assessed as a No Impact through suitable implementation of mitigating measures. No other impacts are predicted for the relevant receptors.
During the post-construction (project) phase, the following changes and impacts were predicted:
Marine ecology and biodiversity: The main long-term impacts to marine ecology are related to the direct impact of the project, given that habitats including coral habitats, macrobenthos and filter feeders on the existing concrete piles, within the physical footprint of the development will be permanently removed. The overall impact is assessed as a Moderate Negative Impact for corals and a Slight Negative Impact for the filter feeders and soft seabed habitat in terms of the lost habitat, and a Minor Positive Impact in terms of the potential new habitat created along the sloped rock revetment of the new reclamation. Minor Negative Impacts from suspended sediments are predicted for corals at Sentosa and Marina South, and Slight Negative Impacts for seagrass at Sentosa and Marina East. Additionally, localised Slight Negative Impact for corals at the eastern side of Sentosa, Marina South and Marina East due to sedimentation caused by localised seabed redistribution are also predicted. However, these localised effects are expected to be temporary as an initial seabed response to the predicted current changes in these areas, and are expected to reduce over time as a new equilibrium is reached. Note also that these changes are expected to start once Phase 1 of the reclamation is completed, so the model results for the Final profile are considered to be conservative. No Impacts are predicted to other marine habitats.
