The property to be provided water service shall be the full gross area within the tract described in the application for plat approval or building permit, including all common areas and areas dedicated to public use such as, but not limited to, parks and street rights-of-way. The public works director is authorized, upon application of the developer or property owner, to establish the boundaries of the property to be provided water service referred to in this code, which may be less than the entire parcel owned by the application to exclude portions of the parcel that shall remain unimproved. In no event shall either parcel be less than the minimum lot size permitted; and provided further, that the owner shall sign a “partial pay agreement” whereby the owner agrees to pay the connection charge in effect at the time the remaining parcel is connected to the city water system; and the partial payment must be based on the minimum base zoning. In no event shall the total parcel size be less than five times minimum base zoning to qualify for the partial payment exemption. (Ord. 1634 § 1, 1996).
