Beaches on borrowed time

Coastal erosion has been a thorn in the side of beachfront property owners in recent years, growing into a major concern for communities along the shoreline. And it is not just about the loss of natural recreational spaces.

For established beachfront neighbourhoods, the shrinking sandy beaches have raised prickly questions about property values, maintenance costs and the long-term attractiveness of coastal investments.

According to a statement by Penang’s Infrastructure, Transport and Digital Committee chairman Zairil Khir Johari in January this year, erosion along the state’s northern coastline is considerably more severe this year than in previous years.

Affected locations include coastal stretches near Mercure Hotel, Skyhome Apartment and the Chinese Swimming Club in Tanjung Bungah, alongside several established hotels in Batu Ferringhi.

The state government has since pursued mitigation measures, with the federal government approving RM61mil for a longer-term coastal protection project under the 12th Malaysia Plan.

For beachfront property owners, however, how can a premium location retain its appeal when the natural surroundings that support its value become more and more vulnerable?

A once premium location becomes a liability

Proximity to amenities, connectivity and transport links as well as recreational attractions are some of the usual checkboxes that need to be ticked for a buyer to consider a property.

However, beachfront properties have the added special appeal of their coastline. It sets them apart from homes further inland, like a private retreat to enjoy nature.

Yet unlike a building’s facilities or interior finishes, the condition of the surrounding beach is not controllable like those of inland properties. Honestly, the condition of a beach is beyond anyone’s control.

What happens after? As the shoreline retreats, it can be said that the distance between the sea and built structures gets narrower and narrower.

The sand that was once used for recreational activities then becomes less accessible. New structures to protect the beach are installed and the highly sought-after uninterrupted beach views are lost.

For those who stay on high-rises on the beach, they would probably continue enjoying uninterrupted ocean views but the disappearance of the doorstep beach would entirely change the lifestyle experience they originally signed up for.

But whether these changes translate into lower selling prices and property values is less straightforward because those are dependent on some other factors too, including accessibility, building conditions, surrounding amenities and market demand.

So for established neighbourhoods like Tanjung Bungah and Batu Ferringhi, finding evidence of the direct relationship between erosion and declining residential property values goes beyond mere tracking of the transactions.

The price of protecting paradise

The cost of coastal erosion is not just the potential loss of land because protecting an exposed shoreline can require substantial investment even before permanent solutions are put in place.

In July 2026, Penang’s Department of Irrigation and Drainage (DID) began installing 62 beach containers, also known as sandbags, along a 44m stretch of Batu Ferringhi beach near the Lone Pine Hotel. The RM500,000 project is designed to reduce wave impact and slow erosion at one of the most severely affected sections of the shoreline.

According to Zairil, the temporary protection is expected to work for approximately two to three years but it also depends on weather conditions, tidal movements and wave activity.

This shows the tough recurring nature of coastal protection expenditure. An intervention may reduce immediate risks but maintaining a stable shoreline is a whole other issue that requires further work as coastal conditions change.

DID has identified several methods of managing erosion, including breakwaters, revetments, groynes and beach nourishment. Each serves a different purpose, with suitability depending on local wave conditions, sediment movement and the surrounding environment.

Beach nourishment, for instance, involves adding sand to replace what has been lost through erosion. It is not a one-off exercise, however. DID’s technical guidelines suggest that more sand may be needed every five to ten years, depending on the conditions at the site.

Other methods have their drawbacks too. Revetments, for instance, help shield the land from waves but the reflected wave energy can cause further erosion nearby. This presents another challenge for coastal developments, as efforts to protect buildings may also affect the beaches surrounding them.

Impact on the hospitality industry

The livelihood of hotels that advertise beachfront access is also at stake.

The Statistics Department reported that the state recorded 17.7 million domestic visitors in 2025, generating RM8.5bil in domestic tourism receipts alone.

As Penang is famous for its culture and beaches, many businesses depend on tourism-related activities like water sports to get by.

However, erosion does not necessarily mean an immediate drop in tourism demand.

The more famous destinations could continue attracting visitors through their accommodation, dining options and other attractions.

Who bears the responsibility?

Protecting the coastline also raises questions about the responsibilities of public authorities and private property owners.

For developments located near erosion-prone areas, the boundary between public coastal infrastructure and privately maintained property can become particularly important.

A management corporation may be responsible for maintaining structures and facilities within its development but larger coastal protection works could involve local authorities, state agencies and federal funding.

The responsibility for individual projects would depend on land ownership, the nature of the affected structures and the relevant legal and administrative arrangements.

In Penang, the approved RM61mil project involves proposed coastal protection and outfall structures that aim to reduce erosion and stabilise affected areas.

Meanwhile, DID is reviewing the Penang Integrated Shoreline Management Plan, which is scheduled for completion in the third quarter of 2027.

The findings will help the state identify beaches most at risk of erosion and determine where protection works are needed.

The problem is not confined to Penang. DID’s published data show that some 1,347.6km of Malaysia’s coastline is affected by erosion. Of this, 55.4km is considered critical while another 375.9km falls under the significant erosion category.

The department’s National Coastal Erosion Study 2015 also sets out guidelines on how far developments should be built from the shoreline, taking into account the severity of erosion in different areas.

These are matters that developers may have to give more thought to when planning beachfront projects.

Apart from assessing the condition of the coastline, there is also the question of how much it would cost to protect the area in the years ahead.

For buyers, a good sea view may be attractive but the condition of the surrounding beach is worth looking into, especially if they intend to keep the property for many years.
