Donations are expected to cover the $1.2 million cost of building new stables to house the horses that will be party of the re-established Philadelphia Police Mounted Unit.
The new stables for about 40 horses will be built in Fairmount Park near an existing stable facility.
Last year police officials announced plans for the mounted unit's return. It was disbanded in 2004 because of funding problems.
Police Commissioner Charles Ramsey says the mounted unit will be able to patrol in areas not accessible by car and would be used for crowd control.
The Philadelphia Police Foundation is running a fundraiser to cover costs. About $400,000 will be saved through the donation of construction services.
The mounted unit currently has 12 horses.
