6. Water-Efficient Landscaping Design Standards. In addition to the lawn and turf restrictions set forth CZC 12.51.065 (Lawn and Turf Restrictions), the following water-efficient design methods and practices should be implemented for all landscaping designs and plans.
   1. Ninety percent (90%) of all plant materials should be drought tolerant and water-efficient plantings, as listed or depicted in various water conservation demonstration gardens in Utah or as recommended by a landscape architect. 
   2. Rock, mulch, or other similar materials used in planting beds or other areas should have a depth of at least three to four inches to prevent weed growth and retain soil moisture and should be permeable to air and water. The use of rock, mulch, or other materials in the parkstrip is restricted by City ordinances, including, but not limited to CMC 11.02.020 (Parkstrip Landscaping and Hardscaping).
   3. Soil scarification (the process of breaking up soil by fracturing or tilling) should be performed to a depth of at least six inches (6") to allow for water and air exchange in soil following site work compaction in all landscaped areas.
   4. Soil amendments (organic material) should be added and tilled into the soil to a minimum depth of six inches (6") to increase organic content and improve water retention in all landscaped areas.
   5. Irrigation systems should be designed with water-efficient controllers, valves, drip emitters, and bubblers that provide the minimum necessary amount of water to ideally sustain the landscape plantings (e.g. WaterSense labeled smart irrigation controlled systems).
   6. Appropriately designed drip irrigation systems should be used for all non-turf landscaped areas.
   7. Planting areas should be irrigated with low-volume drip irrigation systems. Low-volume drip emitters should be rated at 5 gallons or less. Micro-spray emitters, bubblers, and soaker hoses are not considered low-volume drip irrigation.
   8. Overhead sprinklers (generally used for lawn, turf, or other landscaping) should not be on the same irrigation valve or zone as drip irrigation (generally used for plants and shrubs).
   9. Drip irrigation systems should be installed with filter and pressure regulators.
      
   10. In addition to ordinance requirements set forth in this Chapter, total landscaped areas for projects should have at least 35% plant foliage coverage at the plant's maturity. Annual flowers and other annual plants and flower bulbs are generally not used to calculate the 35% recommended plant foliage coverage.
       
7. Watering Times. Irrigation operation and watering shall only be permitted between the hours of 6 p.m. to 10 a.m. to reduce loss from wind and minimize evaporation or as restricted by other local, special service district, county, or state regulations, including, but not limited to CMC 9.02.210 (Sprinklers).
8. State Law Restrictions. Pursuant to Utah Code § 10-20-619, the City is prohibited from enacting or enforcing an ordinance, resolution, or policy that prohibits or has the effect of prohibiting a property owner from incorporating water wise landscaping on the property owner’s property.

The South Main Street Corridor has been designated by the City as an important historic and cultural focal point of the City and properties within the SMSC Overlay Zone are subject to heightened design standards enacted to preserve the historic character of this area, to encourage development that is sensitive to the City's heritage, and to provide a gathering space and cultural heart for the community by fostering a small town atmosphere.
