16-805 Installation of Improvements.

The subdivider shall install the following improvements in a timely manner and in accordance with plans, specifications, and data as approvend data as approved by the City Engineer.

(A) Sanitary Sewer System.

There shall be constructed at the owner and subdivider's expense, a sanitary sewer system including all necessary pumping stations,* pumping equipment,* manholes and all other necessary or desirable appurtenances to provide for the discharge of sanitary sewage from all lots or parcels of land within the platted area to a connection with the City's sanitary sewers. The sanitary sewer system shall be constructed in accordance with the plans and specifications of the City and at the sewer grades approved by the City. The installation of the sewers shall be under the supervision and inspection of the Department of Public Works, and the subdivider may be required to pay a reasonable charge for the engineering and inspection service.

Under some circumstances the City may require, as a condition for approval of the plat, installation of a sanitary sewer that is larger than necessary to meet the needs of the platted area or the area being subdivided as shown by the Preliminary Plat or Site Plan but necessary to complete the City sanitary system as it relates to both the area being platted and other areas.

*Pumping stations and pumping equipment will not be permitted by the City unless all means of gravity flow are unavailable or undue hardship would result; increased costs, unless they constitute an undue and prohibitively excessive financial burden as determined by the City, will not constitute a hardship.

(B) Storm Drainage System.

There shall be constructed, at the owner and subdivider's expense, a storm drainage system adequate to serve the area, including anticipated extension of use to serve additional areas.
