Louise Duffy has minded her father's ashes since before lockdown, waiting until the family can meet to scatter them to the waves on his beloved beach as he wanted.
But she has made an even bigger promise to honour her late dad's memory. She has sworn to save the house that was his pride and joy from the same waters he loved so much.
Coastal erosion has ripped away gardens, collapsed sheds, sliced a miniature golf course in half and even demolished an entire house in their small north Co Dublin community in the past two years.
Louise and her neighbours now fear they are in a race against time to save their remaining land and property.
Her father, Dermot, bought the chalet on The Burrow peninsula in Portrane in the 1970s.
With the Rogerstown estuary on one side and the open sea on the other, the peninsula is a natural jewel.
Every summer Louise's eight-strong family decamped from their Dolphin's Barn home in Dublin's inner city to spend two blissful months playing in the dunes and splashing in the waves.
The siblings carried on the tradition when they had children of their own and since Louise moved there full-time two years ago to renovate the property as her permanent home, she has continued hosting the family get-togethers. In those two years, however, the erosion that has chipped away at the beach and dunes for decades accelerated at an alarming rate.
More than 15 metres of beach has disappeared in some parts. The boreen that provides the only access for Louise and 10 of her neighbours on Beach Lane is now fully exposed to the sea and has partly crumbled away. The dunes where she used to spend hours in play have shrunk to a narrow strip.
"It's upsetting, knowing how important this place was to my dad and all the good times we had here, and now my nieces and nephews might not be able to enjoy it the way we did," says Louise.
"It's also worrying because if it goes, I'm homeless."
A few hundred metres away, Sharon Shevlin and her family have already had the unnerving experience of losing half their garden to the sea.
"We were out for Valentine's and when we came home, the shed was hanging over the edge of the dune," she says.
That is minor compared to her sister's loss, During Storm Emma in 2018, Grainne Hennigan lost all the land to the rear of her home. A year later, the back of her house fell away too.
Sharon looks over a fence, made from the remains of her decking, which also disappeared on Valentine's night.
Below her, 20 metres away, the first of three rows of concrete bollards known as Seabees marks the point to which her garden used to stretch.
"We've rebuilt that fence five times," she says, "and each time, it's closer to the house."
The Seabees are not pretty to look at. "They're unsightly. There's no point pretending otherwise," says Joe Kennedy, another local resident.
Aesthetics are not his chief concern, though. He fears the Seabees, installed by Fingal County Council as a temporary measure, will not hold back the sea long enough to implement a permanent solution.
"They're already sinking," he says, pointing to the outer row, which is embedded in half a metre of sand. Almost 400 Seabees were installed along 300 metres of beach in 2018 and 800 more were added in recent weeks to extend the protection up to almost 1km.
But locals say the first tranche merely diverted the waves to unprotected stretches of the beach and worsened the impact there.
If that is the case, it is hugely worrying for Louise Duffy. The extended line of Seabees stops just short of her home and the next 10 properties,
"The council says we don't need protection because we're further back and not in immediate danger," she says.
"But the other houses were further back from the sea at one point too. I thought the point of protection was so that you wouldn't find yourself in immediate danger."
Fingal County Council has had several consultants' reports and says the current assessment is that the area beyond where the Seabees sit "does not warrant further coastal protection".
It adds it "does not have any information to indicate that the installation of the Seabees will in any way exacerbate coastal erosion at Beach Lane".
The council also points out: "It should be noted that local authorities do not have a remit in relation to the protection of private property from coastal erosion."
That is frustrating for the residents who have spent time and money laying stones to shore up the boreen and dunes to protect their own properties but have been cautioned that the works are unauthorised.
"So the council won't protect our homes but we're not supposed to either," says Joe Kennedy. "The irony is that the dunes are protected so we're not supposed to interfere with them but there's hardly any dunes left to protect now because of the erosion."
He questions the effectiveness of the Seabees, which have been installed free-standing, upright and spaced out.
They are designed to be laid on their side on hardcore, interlocking in a honeycomb arrangement to form a wall that allows crashing waves to use up their energy swirling around the chambers before dribbling back to sea.
Fingal County Council said its expert advice was that: "The placement of hard foundations under the Seabee array or their positioning as a permanent feature would not be in accordance with the planning constraints and requirements which apply to this section of coastline.
"It is further recommended by our consultants that a solid array as described would likely cause problems with intensified erosion on adjoining sections of the coastline."
The Seabees are meant to be only temporary. Longer term, the council is looking at building groynes out into the sea. But their ideas need to go for public consultation and then planning and the process is on hold in the current crisis.
"And will they have the money then with all that's happening?" wonders Lesley Carragher, whose family have owned the house next door to Louise for more than 40 years. "Will there be anything left to save at that stage?"
Those questions haunt many residents, not just in Portrane but all around the coast from Doonbeg to Donegal, across parts of Kerry and all down the east coast, where homes have been lost in Co Wexford and Irish Rail has major concerns about its tracks in Co Wicklow.
Erosion has been happening for years but there is no national policy on whether it should be allowed to happen or prevented, what kind of property should be protected and who should pay for it.
These are all questions that become more urgent as climate change raises sea levels and increases storm frequency and intensity. A 2017 study commissioned by Fingal County Council surveyed 19 local authorities in coastal counties and found they wanted a national coastal strategy to enable a joined-up approach to be taken.
Earlier this year, the Government agreed to set up an interdepartmental group to "scope out the approach for the development of an integrated, whole of Government coastal strategy for managing our changing coast".
The Office of Public Works, which was to be joint chair with the Department of Housing, said this week it was still the intention to form the group. Portrane's residents know they may not like what conclusions it draws, if and when it gets down to work.
A consultants' report raises the option of long-term "withdrawal" from the peninsula, meaning no protection works would take place and nature and climate would be allowed to take their course. Some 350 homes and buildings could ultimately be affected.
That option is not being explored by Fingal County Council but Sharon Shevlin says it will be the default position if a solution is not found.
"We're not being told we have to leave. I don't think that would ever happen. But if something isn't done quickly and our home is lost, that's kind of the same thing."
