Businessman and frontrunner for the Republican Presidential nomination Donald Trump might be strengthening his grip on the GOP, but it's not going all his own way across the Atlantic Ocean.
Thirty-meter waves and driving rain have been eroding his coastal golf resort in Doonbeg, west Ireland. So much so that the resort submitted last week a plan to build a 20 meter-wide defensive barrier -- or wall -- of limestone rock.
The consultants on the wall, acting on Trump's behalf, have warned County Clare Council that turning down the application would have dire consequences for the local area.
"In the medium term, the do-nothing scenario will bring the viability of the entire resort and its potential closure into question," the consultants, acting on Trump's behalf, said in the application.
They also state that it would result in a "permanent and profound negative economic impact upon Doonbeg, its hinterland and the wider context of County Clare."
Trump invested a reported 15 million euros ($20 million) back in February 2014 for the golf resort, which the application highlights has the ambition to one day host the Irish Open.
But, alongside the receding coastline, the real estate mogul has had to deal with plans to build wind turbines in close proximity and an endangered microscopic snail that needs preservation and constant surveillance.
A quick fix solution to his resort falling into the sea -- dumping tons of rocks on the site -- in 2014 led to Trump coming head-to-head with local authorities, who served him with an enforcement notice. He then had a plan involving metal bars into the edge of dunes, which would allow the sand to naturally form once more. This, however, never saw the light of day.
This new idea might not be as controversial as his talk of building a wall between the U.S and Mexico, but it has already raised the eyebrows of local campaign groups. Tony Lowes, a New York-born director at Friends of the Irish Environment called the plan a "monster sea wall" and confirmed to CNBC that the group would be objecting to the application.
Trump's other European golf course, in Scotland, and some nearby wind turbines, are also causing him a major headache. Indeed, a very public war of words has broken out in recent months between himself and the former first minister of the country, Alex Salmond.
However, back in Doonbeg village, local people who have asked to remain anonymous have told CNBC that the town is keen to have jobs in the area and attract the more wealthy individuals that a top class golf course could bring. The new application states that the hosting of a major event at the course would boost the regional tourism economy by 14.5 million euros.
A decision from the council is due on April 18.
