§ 37-605. Irrigation systems; application of water.

(a)

New or substantially altered irrigation systems. All irrigation systems installed or substantially modified after July 20, 2008, shall comply with the requirements set forth in this paragraph:

(1)

Irrigated zones shall receive only one (1) form of spray, rotor, drip or other irrigation application.

(2)

Irrigated turf areas shall be on separate irrigation zones from other landscape plant groupings.

(3)

Overhead or spray landscape irrigation may be used for turfgrass and other ground cover having a mature or maintained height of no greater than one (1) foot. All other landscape plants, including but not limited to trees and shrubs shall be irrigated using only micro-irrigation at the base of the plant or within the dripline of a tree, as appropriate, or by handheld hose or watering can.

(4)

Landscape areas, including turf areas, measuring four (4) feet or less in width, shall be restricted to micro-irrigation and meet applicable landscape requirements set forth in chapter 24. This provision shall not be applicable to turf located on rights-of-way.

(5)

Notwithstanding any other provision of this section, no retrofitting shall be required so long as the substantial modification to an irrigation system causes a net decrease in the flow or volume produced by the emitters.
