706.          Water Supply. A culinary water supply, which must be approved by the Engineer and State Board of Health, shall be available to each lot in the subdivision and shall be provided in conformance with the standards and rules and regulations of the municipality.

710.          Irrigation Ditches, Canals and Hazards.   Open irrigation ditches and canals are prohibited within or adjoining a subdivision except along rear and side lot lines.

711.          Landscaping. The City Engineer may require sub-dividers to provide ground cover where it is determined that soil erosion may be a problem, where surface water may flood portions of the municipality or damage municipal property, or to prevent the growth of noxious weeds which may become a nuisance, fire hazard or danger the public health.  The City Engineer may specify the types of ground cover to be installed on any vacant lot, open space, drainage area, swale or planting strip in order to accomplish the provisions of this section.  (Res. 01-14)

When, in the opinion of the Council, it becomes desirable to construct such structure, it shall be constructed by the municipality applying the deposit toward the construction costs and charging the other one‑half of such cost to the person developing the opposite side of such obstruction, or if there is no person so developing the other side, the half shall be borne as a municipal expense.
