7.12 Planters

Planters are useful in places where it is difficult to plant a tree, particularly in dense built-up areas with little green space.

They should be made out of good quality material that reflects the local character – wood is particularly encouraged – and should be large enough to allow for the growth of the tree or shrub.

Planters can also be used as an attractive way to close off a street to traffic, in place of bollards.

Planters must be placed to leave a clear pavement width of 2m. This can be reduced to 1.5m over short distances.

Planters also require frequent maintenance and irrigation, and so must only be used where there are no other feasible options, such as above a basement or podium slab, or where there is a very high concentration of below ground utilities, or if a temporary solution is required. It must always be a priority to plant into the ground.

The highways team could work with residents, businesses, schools, and other organisations to assist in the watering and maintenance of any planters, especially while the planting is becoming established. This will require early community engagement and relationship building but can reduce ongoing costs.
