In the event the City determines it is not currently necessary to provide some of the required improvements, the City may authorize an agreement to pay for future improvements in the form of a Waiver of Remonstrance and an Agreement to pay a fair share of the required improvements when they are provided, or the improvements may be installed in the area under special assessment financing or other facility extension policies of the City. Deed covenants shall be attached to each property's deed, specifying this commitment as an obligation perpetually attached to each property, regardless of sale or ownership.
