Pearl City permits native Hawaiian species as landscape substitutions under LUO Sec. 21-4.70, a water-wise option for condo common areas and single-family yards near Pearlridge.
Pearl City's central Oahu microclimate supports a wide range of native and Polynesian-introduced plants, from naio and lama to milo and kou, that tolerate warm, periodically dry conditions. Under LUO Sec. 21-4.70 (landscaping and screening), native Hawaiian species are permitted as substitutions for standard street tree species. No mandatory native-only requirement exists. The Board of Water Supply Xeriscape Program and the Oahu Planting Guide offer voluntary guidance, which is useful for condo HOAs in Pearlridge trying to reduce irrigation bills on shared landscape areas.
Non-compliant landscape plans can be rejected by DPP, but native substitutions are commonly approved and rarely a source of enforcement action.
