Aberdeen City Council is going ahead with substantial investments to combat severe erosion at Aberdeen beach, firmly rejecting any proposals for a “managed retreat” from the coastline. The local authority has earmarked £2.5 million for urgent repairs to the seawall, a critical structure beneath the Esplanade, part of which collapsed in late 2024 due to persistent erosion.
Meanwhile, expert consultants have been engaged to develop a comprehensive plan to address the ongoing degradation of Aberdeen beach. This investment runs parallel to a broader £50 million beachfront regeneration project, which includes the development of new parks and an amphitheatre, aiming to transform the area into a premier destination. This wider regeneration is part of a £150 million commitment to improving the city centre and beachfront.
The challenges facing Aberdeen’s coastline are not new. Decades of coastal erosion have significantly lowered sand levels, leading to the closure of several staircases on the popular Queens Links to Footdee stretch due to safety concerns. An estimated 140,000 tonnes of sand have been displaced, creating drops of approximately six feet in some areas.
Warnings about the vulnerability of the beach and its defences were highlighted in 2023 by expert engineers from HaskoningDHV, who identified an “urgent” risk of erosion particularly in front of the Beach Ballroom. The firm, a leading consultancy in coastal management, advised the council to develop a strategy for interventions across the entire Aberdeen coastline, from Cove to Blackdog Burn.
Roads manager Claire Royce, whose prior responsibilities included coastal engineering, informed councillors about the extensive nature of the problem, stating: “Some works will be required between the next five and 30 years. It’s quite well known that there are problems with the seawall along its entire length. We recognise there is a lot of investment needed in the seawall.”
The seawall itself was constructed in two primary phases, in the 1930s and 1960s, with inspections revealing erosion of its crucial toe beam.
A key issue has been the intermittent nature of beach nourishment. The last significant replenishment of sand occurred in 2006, when 70,000 cubic metres – equivalent to 28 Olympic-sized swimming pools – were dredged and placed over two weeks. Rock ‘T groynes’ were also installed then, complementing earlier wooden groynes from the 1930s to help retain sand.
However, plans for continuous nourishment, which experts suggest should happen every few years, were never fully implemented. Ms Royce noted: “The idea when the rock groynes were put in was that the beach would be recharged with sand and it’s never been done.” While the rock groynes are “doing their job” in their immediate vicinity, she indicated that “further south towards Footdee is an area of concern” requiring protective measures for the seawall.
The prospect of additional beach recharging, estimated to cost at least £1 million for the southern end alone, raises questions about the long-term financial viability of such interventions. Across the UK, beach nourishment on exposed North Sea coasts like Aberdeen can cost between £4,000 and £8,000 per metre. This has led to critical inquiry, with independent councillor Alex Nicoll asking if the city was “putting good money after bad” in a battle against nature.
Ms Royce acknowledged the complexity of the situation, explaining that Aberdeen City Council is collaborating with other coastal authorities on a coastal adaptation plan to assess options over the next century in response to climate change.
Despite these considerations, council co-leader Ian Yuill firmly reiterated the administration’s stance: “This Lib Dem and SNP partnership certainly has no plans for ‘managed retreat’.” The concept of managed retreat involves allowing the coastline to naturally recede, often through planned relocation of infrastructure and communities, rather than maintaining existing defences.

Down the Scottish coast, Montrose is also undertaking significant efforts to replenish its beach and dunes following severe erosion, with projected costs running into millions.
There will no doubt be some who question why the city council is investing so heavily in the likes of the new playpark and an amphitheatre when conservation work should take precedence.
The expert report detailing options to protect Aberdeen’s seawall and the potential need for further beach top-ups is anticipated later this year.
