A.
It is the intent of the City to ensure the quality in land development and to ensure that each development pays its share of the cost of public facilities and services. The City will encourage the use of planned developments employing innovative techniques for the design of functional and aesthetic neighborhoods that maximize open space and preserve the natural environment. Subdivisions shall be served by public water and sanitary sewers and by public streets.
B.
Prior to final approval and acceptance of improvements and prior to the issuance of any building permits in a subdivision located within the corporate limits and extraterritorial plat approval jurisdiction of the City of Watertown, the subdivider shall install public improvements as hereinafter provided. These improvements may be installed in plat phases approved by the Plan Commission and public improvement phases approved by the Public Works Commission. No building permit may be issued for construction outside of phases of the plat that have not had plans fully approved by the City. Building permits may be issued upon substantial completion of public improvements as defined in § 236.13(2)(am)(2) Wis. Stats. Occupancy permits shall not be issued prior to the completion, inspection, and acceptance of all requirement improvements.
