Yards and setback areas shall be landscaped with lawn, trees, shrubs, or other plant material, and shall be permanently maintained in a neat and orderly manner and substantially free of weeds, debris and dead, diseased or dying vegetation and broken or defective decorative elements of the landscaped area. Foliage in landscaped areas shall be mowed, groomed, trimmed, pruned and adequately watered so as to maintain healthy growing conditions and not detract from the appearance of the immediate neighborhood. Irrigation systems shall be maintained to prevent public health or safety hazards.
If you are proposing to modify your front yard with drought-tolerant landscaping, Planning Division approval through an over-the-counter application called a Zoning Clearance is required. Please submit a Uniform Application, a site plan (example) showing property line dimensions, details and location of the proposed landscape/decorative hardscape improvements (e.g., quantity and species of all drought tolerant plants, shrubs, trees, and decorative hardscape areas).
For a list of drought tolerant landscaping, refer to the CAL-IPC website and the L.A. County Drought Tolerant Handbook for some ideas. https://www.cal-ipc.org/
