The Central Core area is the most intensively used area of the City, and the landscape treatment here should reflect this condition. Landscape features should be arranged in more formal patterns than elsewhere in the City. Hardscape elements should also be more refined and more apparent. Design elements appropriate to this area include a variety of distinctive street trees, decorative lighting, enhanced paving, flowering accents and the generous use of evergreens to help set the theme for the rest of the City and frame the City’s picturesque mountain backdrop. Traditional plant material such as the cedars, Texas Umbrella, fruit trees, Date Palms, California Pepper, Eucalyptus and Juniper which have been established in the older areas of the Central Core area should be preserved whenever possible and reinforced with similar plantings.
