Kailua landscaping may substitute native Hawaiian species for standard plantings under LUO Sec. 21-4.70; no native-only mandate exists.
Kailua's beach dune areas and windward slopes are natural habitat for native species like naupaka kahakai, pohinahina, and ilima, which many homeowners favor for salt tolerance and low water use. LUO Sec. 21-4.70 governs landscaping and screening requirements in zoning districts and permits native Hawaiian species as substitutions for standard street and buffer plantings. No city ordinance mandates native-only landscaping. The Board of Water Supply Xeriscape Program and the Oahu Planting Guide offer voluntary design guidance. For beachfront properties, native dune plants often satisfy shoreline setback revegetation conditions imposed by the Department of Planning and Permitting.
No penalties for choosing non-native species, but substandard landscaping for commercial zoning can delay permit approvals under LUO Sec. 21-4.70.
