Get Involved for Coastal Protection

City-East Coast

PUB began engaging the nature group community on the plans and approaches for City-East Coast in 2021. We also sought their feedback on the scoping of the environmental baseline survey for this segment of the coastline.

In Dec 2021, a follow-up site visit to Marina East was held, where PUB gained a better understanding of the ground conditions and nature group representatives shared their insights.

Our Coastal Conversation officially kicked off in October 2022. 135 participants from diverse backgrounds engaged in lively discussions over two sessions on how we can accommodate and balance different needs and aspirations when planning for coastal protection measures.

Minister for Sustainability and the Environment Ms Grace Fu listening in and interacting with participants who shared about their aspirations for the coastal areas at the session.

Participants also discussed the trade-offs of different options with then Senior Minister of State for Sustainability and the Environment Dr Koh Poh Koon and then Senior Minister of State for National Development Mr Tan Kiat How, who attended the second session on 28 Oct 2022.

Summary of key points raised during the sessions

To broaden the engagement base, we initiated our first grassroots organisation outreach with the Radin Mas Citizens Consultative Committee (CCC) in July 2023 to gather community feedback on the potential coastal protection measures.

We also engaged grassroots organisations in Siglap, Telok Blangah, and Tanjong Pagar-Tiong Bahru. These towns were selected due to their location along the coastlines. Their insights helped us gather community support for the proposed measures and address local concerns and preferences.

Youths rise to the challenge

Launched in February 2023, the “Living with the Rising Seas” Ideas Competition by PUB invited students from local tertiary institutions to demonstrate ideas to protect the South-eastern coastline of Singapore in the face of rising sea levels while achieving liveability, flexibility, and sustainability. The competition attracted a total of 32 entries submitted by more than 110 students from eight tertiary institutions including Ngee Ann Polytechnic (NP), National University of Singapore (NUS), Nanyang Technological University (NTU), and Nanyang Academy of Fine Arts (NAFA).

The competition provided a platform for cross-domain teams to work together, such as a team from NUS, which consisted of students from integrated sustainable design, as well as sustainable and green finance backgrounds. The ideas and concepts from the competition may be considered in the formulation of coastal protection measures by PUB.

Journey of the students

14 shortlisted teams got a chance to share their ideas with a multi-disciplinary panel of judges comprising representatives from PUB, the Urban Redevelopment Authority (URA), National Parks Board (NParks) and PUB’s consultant for the City-East Coast site-specific study. The jury eventually selected a total of nine top entries (three top entries per typology), which demonstrated creativity and originality in developing integrated solutions for coastal protection, while retaining distinct characteristics of the south-eastern coast.

Explore the winning ideas!

Participants were challenged to develop ideas and design concepts for one of three coastal typologies, and illustrate how their ideas can be applied to a particular stretch along the South-eastern coastline from the Greater Southern Waterfront to East Coast. Winning entries are in no order of merit.

Building on the success of the inaugural OCC, PUB conducted further sessions for the Changi and Greater Southern Waterfront in October 2023. Over 50 participants from diverse backgrounds joined the dialogue.

One key takeaway was that no single coastal protection measure would meet the various needs of the coastal areas. Nevertheless, the participants agreed that there was potential for multi-functional coastlines, which could be realised with prudent long-term planning.

Summary of key points raised during the sessions

We consulted nature enthusiasts and subject experts on the possible coastal protection measures, trade-offs and ways to minimise impact to biodiversity. We also shared the findings of the environmental baseline survey.

At Singapore’s first-ever coastal protection exhibition, we shared Singapore’s coastal protection approach and unveiled the recommended measures to protect the Greater Southern Waterfront and Changi coastline!

The exhibition was held at VivoCity (Level 1 Atrium) from 28 to 31 Aug 2025. It was featured at various locations including Science Centre Singapore, Marina Barrage and Gardens by the Bay.

North-west coast (coastal reservoirs)

The north-west coast (coastal reservoirs) stretches over 24km and comprises four coastal reservoirs (Tengah, Poyan, Murai, and Sarimbun) that are key water supply sources.

An engagement session was held in Oct 2024 with the nature group community.

We worked with members of nature groups to plan and run the focus group discussion. The topics discussed include possible coastal protection measures, and mitigating measures that could minimise impact to biodiversity.

North-west coast (Lim Chu Kang to Woodlands)

The north-west coast from Lim Chu Kang to Woodlands stretches over 15km. This area is home to several nature parks, such as Sungei Buloh Wetland Reserve, Kranji Coastal Nature Park, and Mandai Mangrove and Mudflat.

In Nov 2023, we consulted nature groups including nature enthusiasts and subject experts on the scope of the environmental baseline survey.

PUB partnered NUS’s Civil Engineering Club for the 2024 Built Environment Case Competition (BECC). The competition provides students with an opportunity to address real-world challenges in the built environment space.

The winner, Team CAP 5, suggested constructing a permeable wooden dam with mangroves planted behind. This could reduce coastal erosion, increase sediment accretion in front of Kranji Dam, and create new habitats for biodiversity.

Held in September 2025, participants were joined by Ms Goh Hanyan, Senior Parliamentary Secretary, Ministry of Sustainability and the Environment and the Ministry of Culture, Community and Youth on a site walk around Sungei Buloh Wetland Reserve and the nearby Kranji Dam and Tidal Gatehouse.

Participants delved into lively discussions on how to protect Singapore’s north-west coast against rising sea levels. Over 50 participants contributed diverse perspectives and ideas, and weighed the trade-offs in developing coastal protection measures for this unique stretch of coastline. Participants also shared their views on transiently floodable areas (TFAs) and brainstormed ideas for multifunctionality at Kranji Dam and Tidal Gatehouse.

We collaborated with nature groups experts to organise an engagement session with the nature group community. More than 30 nature enthusiasts and subject experts participated in this session. Participants shared feedback on the possible coastal protection measures, and thoughts on how these measures can be implemented in an environmentally sensitive way.
