The approved methods of controlling weeds shall be mowing, cutting, digging, chemical treatment or other methods designed to remove the weeds but not disturb other vegetation or unnecessarily disturb the soil. The scraping and tillage of lots and tracts of land is prohibited, unless permission of the City Manager is first obtained; except that scraping and tillage as part of normal construction activities or as ground preparation for agriculture or landscaping activities shall be allowed. The City Manager may allow scraping and tillage of lots or tracts of land when this will not detract or violate the clear intent and purpose of this chapter. (Ord. 505, 2012)
