Roots were able to grow under the curb and pavement in this landscape. Trees are growing well as a result. Some landscapes are designed inadvertently to allow roots to escape the parking lot island. Curb and pavement often become displaced and can be regarded as a hazard to pedestrians when roots escape the island. So, this is the dilemma: when roots escape, trees grow well but infrastructure is damaged; when roots do not escape, they quickly run out of useable soil and trees grow poorly. We need a better designed system in order to develop more sustainable landscapes.
