A. All landscaping, excluding single family detached dwellings, shall have an automatic controlled irrigation system to water the landscaping, including the park strip area fronting the property. Single family detached dwellings are encouraged to have a similar system and certain programs may require the installation of such a system.
B. Individual hydro-zones shall be implemented to assure efficient irrigation relative to the layout and requirements of the vegetation. When a drip system shares a zone with spray heads, the spray heads must have appropriately sized nozzles that provide a matched precipitation rate to that of the drip emitters where equal precipitation values are desired.
C. Drip irrigation or bubblers shall be used to irrigate plants in all non-turf grass planting areas.
D. The following are drip irrigation requirements:
1. Each zone will have an automatic zone valve.
2. A strainer will be placed downstream of the zone valve.
3. A pressure regulator will be placed downstream of the strainer and upstream of the emitters.
4. A flush cap will be placed downstream of the emitters.
5. Irrigation systems supplied by culinary water shall adhere to current backflow requirements as outlined within Ogden City Municipal Code.
E. The properties of the system including line size, pressure, number, and placement of emitters, and number of zones shall provide adequate irrigation to soak the root zone of each plant without creating excessive runoff or saturation that extends below the effective root zone.
F. All valves in the irrigation system shall be controlled by a Water Sense labeled Smart Automatic Irrigation controller.
G. All trees located in the park strip shall be irrigated. When using a drip system, the drip lines shall be placed in increasing circumference sizes of not less than eighteen inches (18") apart extending from the tree trunk to the drip line of the tree. (Ord. 2022-34, 7-5-2022)
