Developers may select either method or combination of methods listed below to comply with the minimum improvements requirements:
A. They may install the required improvements before council approval of the final plat.
B. They may submit a petition or petitions requesting the City to construct street surfacing, sanitary sewer, and water mains in the proposed subdivision by the district method. In that event, the City will prepare plans and specifications for all such improvement districts and shall assess the cost of such improvements to the adjacent property, as provided by law. The size of any street improvement district, sanitary sewer district, or water main district, shall be determined by the city council. Construction of any such district shall be subject to the City's ability to finance any of the improvements. When any length of a full-width street is being dedicated as a part of the subdivision, the subdivider shall install water and sewer lines, without using the improvement district method, prior to the creation of any street improvement district.
C. They may enter into a Subdivision Agreement for the installation of the required improvements.
Sidewalks shall be constructed when the adjacent lot is built upon and shall be regulated and required with the building permit for such lots, unless a waiver to construct when directed by the city council is provided in the Subdivision Agreement.
