Waipahu permits native Hawaiian species as landscape substitutions under LUO Sec. 21-4.70, well-suited for small lots and community gardens along the leeward plain.
Waipahu's warm leeward climate supports native plants like ilima, alahee, and akia that thrive with minimal irrigation. LUO Sec. 21-4.70 (landscaping and screening) permits native Hawaiian species as substitutions for standard street tree species in landscape designs. No mandatory native-only requirement exists. The Board of Water Supply Xeriscape Program and the Oahu Planting Guide offer voluntary guidance popular with community gardens in Waipahu's tight neighborhoods. Native plant palettes can also lower HOA and rental-yard maintenance costs, an important factor for Waipahu's many multigenerational working-class households.
Non-compliant landscape plans can be rejected by DPP, but native substitutions are widely accepted and rarely the subject of enforcement.
