If trees or shrubs are unhealthy, dead, or dying, they must be replaced. It is your responsibility to maintain the landscaping. You cannot remove healthy trees without permission from the Planning Division. If you want to remove a healthy tree, you may need to fill out a land use application and replant trees at a ratio of two new trees for each one removed. Additionally, certain types of trees are protected and may need a permit for removal, even if they are part of your landscaping. 

Some businesses worry that trees may block the view of their signs. They might want to cut or drastically trim their trees. However, removing more than 30 percent of a tree's crown is considered tree removal. This may lead to needing to remove the tree and replanting two trees for each one topped. While small trees may temporarily block a sign, allowing trees to grow will eventually provide a clear view below their branches. 

Landscaping rules require a certain percentage of shade trees and plants that grow to specific sizes and heights. You can replace dead or dying trees or shrubs with the same or similar species. However, do not replace a shade tree with a smaller ornamental tree or large shrubs with much smaller ones. The Planning Division can help answer questions about what is required for your property. 

No, you cannot store materials, display merchandise, or keep vehicles for sale in your landscaped areas. Required landscaped areas are meant for trees, shrubs, bark dust, mulch, decorative stones, and water features. Some landscaped areas may be changed into pedestrian plazas with paving stones and benches, but you must consult with and get approval from the Planning Division. 

Any action that damages the trees is treated the same as removing the tree. This may require you to replant trees at a ratio of two new trees for each one damaged. You may also face civil penalties. 

Prohibited Activities

The following activities are prohibited in landscaped areas because they can damage or kill shrubs and trees: 

• Applying toxic substances
• Operating equipment and vehicles
• Storing materials
• Changing the natural grade through unapproved excavation or filling
• Unapproved alterations of natural physical conditions

No, you cannot pave required landscaped areas without getting prior approval from the Planning Division. 

Many developments have green stormwater infrastructure, which may include ditches or basins. These areas hold and store water and have low plants that help clean the water before it goes into the stormwater system. These features are usually part of the approved stormwater system for your property. In some cases, these areas also count towards your landscaping requirements. You cannot pave, fill in, or remove the plants in these areas without prior approval from both the Planning Division and the Public Works Department.
