In order to maintain landscape continuity, safety and visibility for the general public within areas containing traffic signs, pedestrian crossings, railroad crossings and school zones, the following guidelines pertain to all landscape projects within parks, open space and City owned right-of-way.

1. Tree plantings, both in the median, marginal divider and along the parkway, must have a minimum height of 8 feet from the top of curb line. Where extending beyond the curb, low branches should be no lower than 17 feet above the pavement. Shrub plantings must not exceed 2½ feet in height above the top of a curb.
2. Tree plantings in pedestrian areas must provide adequate clearance for pedestrians so as not to create a safety hazard.
3. No tree planting within left turn lanes of medians or marginal dividers will be permitted.
4. Tree plantings should normally be located no closer than 50 feet from the tip of an end of a median, marginal divider or parkway. However, adequate sight distance must be provided.
5. Trees should not be located within 25 feet of any existing and/or proposed light standard, signal standard, regulator or warning signs, or other traffic control device.
6. Trees should not be planted within 3 feet from the back of curb line on medians and marginal dividers.
7. No tree plantings within medians and marginal dividers measuring 6 feet or less in width will be permitted.
