10.38.020   Air Quality, Dust and Dirt.
   No operation or activity (for example, construction, grading, and agriculture) shall cause the emission of any smoke, fly ash, dust, fumes, vapors, gases or other forms of air pollution, beyond any boundary line of the parcel, which exceeds the requirements of any air quality plan or General Plan Air Quality Element adopted by the City. To ensure a dust free environment, appropriate grading procedures shall include, but are not limited to, the following:
   A.   Schedule all grading activities to ensure that repeated grading will not be required and implementation of the desired land use (e.g. planting, paving or construction) will occur as soon as possible after grading.
   B.   Disturb as little native vegetation as possible.
   C.   Water graded areas as often as necessary to prevent blowing dust or dirt, hydro seeding with temporary irrigation, adding a dust pallative, and/or building wind fences.
   D.   Re-vegetate graded areas as soon as possible.
   E.   Construct appropriate walls or fences to contain the dust and dirt within the parcel subject to the approval of the City Engineer. (Ord. 935 § 3 (part), 2015)
