The Standard Tree Protection service includes installation of chainlink fence with t-posts and mulching the ½ critical root zone. There are frequently other tree services necessary for construction sites such as airspading, fertilization, pruning and more; none of these other services are considered in our tree protection price calculator.
Tree Protetion Fencing
As part of our standard tree protection package, we install chainlink fence with t-posts around the ½ CRZ. This is the standard protection from the city's environmental criteria manual. There are scenarios where alternative tree protection is done, but this is most common.
We apply a 4" layer of our power mulch inside the fenced ½ CRZ to provide health benefits to the tree. Some scenarios that require alternative protection methods will receive a different mulching technique.
Alternative Tree Protection
In some instances where the ½ CRZ is impacted by construction or where new construction is immediately adjacent to a tree's ½ CRZ, an alternative tree protection technique is required. In this scenario, we will typically not install chainlink fence around the tree; instead, we will wrap lumber around the trunk of the tree to prevent physical damage to the trunk and install a 8-12" layer of rough mulch over the ½ CRZ to prevent soil compaction. We'll also spread a thin layer of compost under the mulch to provide benefit to the tree.
City regulation also requires that any pruning be comleted by a certified arborist. We will provide tree pruning bids on an as-needed basis and are not incuded in the pricing from our tree protection calculator. Same goes for airspading services; they are not including in the pricing calculator. However, any trenching or other disturbance to the soil inside the ½ CRZ of a protected tree must be performed by an airspade. Any root pruning, if allowed, must be done by a certified arborist. Tree fertilization, if needed, will also be bid separately.
Feel free to email construction plans that show building and tree locations and we're happy to provide a free consultion that includes evaluating your plans and performing a site visit to determine your exact tree protection needs.
