All dedications of property to the City for public purposes shall be made in fee title, except that, in the City’s discretion, a grant of an easement may be taken. All easements must be of sufficient width so as to allow proper maintenance and protection of the facility. All dedications in fee and grants of easements shall be free of liens and encumbrances except for those which the City, in its discretion, determines would not conflict with the intended ownership and use. The City may elect to accept an irrevocable offer of dedication in lieu of dedication of fee title. All dedications shall be made at the time of filing the final or parcel map.
