Excessive waters shall not be drained onto other properties not in the same ownership without written permission from the owner of the adjacent property. The city engineer shall determine whether water drainage shall be determined as excessive. When a ditch or drainage channel under private ownership is to be used, written permission from either the president of the ditch company when in corporate ownership or from all property owners using said ditch must be obtained.

Whenever any surface of a lot, plot, parcel, or portion thereof is excavated, filled, graded, or hard-surfaced with impervious material (i.e., streets, driveways, sidewalks, parking lots, etc.), adequate surface and subsurface drainage shall be provided. The city engineer shall determine whether or not the surface and subsurface drainage is adequate or required. Such drainage will connect directly into the overall site drainage system for the subdivision or development as approved. [Ord. 10-21-2008A § 2].
