Flowering Hedge for Noise Reduction: Mix Evergreen and Deciduous for Year-Round Buffer

Noise Science

Removing the pines increases noise slightly, but a dense hedge + berm is more effective. Sound waves are deflected upward by a berm; a hedge absorbs high frequencies.

Planting Plan

• Berm: 2–3 ft high, 4–6 ft wide, along the fence line.
• Evergreen backbone: Arborvitae 'Emerald Green' or holly, spaced 3 ft.
• Flowering deciduous: Lilac, viburnum, weigela, or rose in front of evergreens.
• Drought-tolerant: All selected for coastal NorCal summer dry.

Local Nursery Is Key

They know which cultivars thrive in your microclimate and soil. Bring photos and measurements.
