Memorial garden for Jersey stabbing victims
Simon Crowcroft, the St Helier Constable, said the money would come from the parish's building reserve.
He said the idea was suggested by the Town Centre Manager.
Izabela Rzeszowska, 30, and her children, five-year-old Kinga, and two-year-old Kacper, her father Marek Garstka, 56, Marta Dominika De La Haye, 34, and her five-year-old daughter Julia Frances were found with stab wounds at a flat in Victoria Crescent on 14 August.
Community support The constable said Havre des Pas was chosen for the memorial garden as it was a favourite spot for one of the children, Julia De La Haye.
Constable Crowcroft said it had also been discussed with the Polish community who were very supportive of the idea.
He said: "A collection was held and there remains a sum of money that may be used to purchase benches and palm trees for the location."
He said the area was also chosen "because we are trying to improve this part of Havre des Pas, St Helier's premier seafront, in our former tourist heartland of the parish so that we can keep these areas tidy and maintain them."
Parishioners will be asked to approve the memorial garden at a Parish Assembly on Wednesday.
