A huge crack in a cliff is threatening a luxury mansion at the same Texas spot where another vacation house had to be burnt down last year because it was so unstable . There are now concerns that the home in a gated community could also collapse and crumble into Lake Whitney about 60 miles south of Fort Worth . The U.S. Army Corps of Engineers told NBC says it is 'very concerned with public safety ' in light of the new crack . Neighbor Steve Mellgren told WFAA : 'It 's getting larger ... it 's getting wider ... it 's getting deeper . ' He said recent rains have seen the crack open even further . 'If it does happen ... if anybody 's near this cliff ... it 's going to be a problem for them , ' he said . 'Could be loss of life . ' There are buoys floating near the cliff , meant to keep boaters away . The Corps of Engineers said Tuesday it will work to 'keep things as safe as possible in the area until the danger has subsided . ' Last year charred debris from a luxury cliff-side home fell 75 feet into a lake below after fire crews set the $ 700,000 retreat ablaze rather than wait for it to crumble into the water as the land faltered around it . The White Bluff home was built on a fault line and was gradually collapsing with the cliff side into the lake . It took less than an hour for the fire to level the home above Lake Whitney . Flames consumed exterior walls after crews spread bales of hay and fuel to ignite flames throughout the expansive home . Neighbor Steve Mellgren told WFAA : 'It 's getting larger ... it 's getting wider ... it 's getting deeper ' The Corps of Engineers said Tuesday it will work to 'keep things as safe as possible in the area until the danger has subsided ' The ground around the home cracked and became unstable until a part of the land gave way beneath the 4,000-square-foot home , leaving pieces of the house dangling off the side of a cliff . Authorities condemned the home and the owners , Robert and Denise Webb , consented to the burn . Authorities said destroying the house was better than waiting for it to topple into Lake Whitney . The cost of removing mounds of debris from the lake could prove prohibitive . Spectators in dozens of boats witnessed the demolition from a safe distance . The home is right next door to the one which was burnt down in June 2014 because it was so unstable . Live television coverage shared the view of the spiraling black smoke coming from the gated resort community . The Webbs purchased the home in 2012 , but a few weeks ago were forced to remove their personal items and relocate . They expressed shock and sadness at losing their lake house . The Webbs , who also have a home along Florida 's Miami Beach , told WTSP-TV that the deterioration of their property has been hard to watch . 'You know , that 's my life there that we 're watching fall off , ' Robert Webb said the day before the demolition . Geologists and inspectors had told them before they purchased the land that the property was perfectly stable , 'and so we bought it in good faith , ' Webb said . The house , built in 2007 , was to have been left to his grandchildren , he said . 'It 's really tough , that house was special and I do n't even know why it was so special but it was special to me , ' Denise Webb said .
