Soil for required landscaped areas should be prepared as provided in this section.
   .010   Mulch.  A minimum of three (3) inches of mulch shall be added (in non-turf areas) to the soil surface and permanently maintained to enhance moisture retention and minimize evaporation.  Nonporous material shall not be placed under the mulch. The mulch shall be of a type and amount that minimizes fire hazards.
   .020   Edge Barriers.  Loose bark or mulch in a planting area located adjacent to a sidewalk or other paved area should be contained by a durable, edge barrier to prevent spreading onto paved areas.
   .030   Wind and Water Disturbance.  Grading should be minimized to avoid disturbance.  Topsoil shall be stockpiled and covered to protect against wind blown particulates, and shall be reapplied during final grading.  (Ord. 5920  1 (part); June 8, 2004:  Ord. 6101 § 41; April 22, 2008:  Ord. 6425 § 23; December 19, 2017.)
