*'''Tree Maintenance''': Inspection and maintenance of all municipally-owned trees shall be conducted by municipal staff or its contractors after the warranty period of the construction contract. This work may include, frequent watering and fertilizing as trees begin to establish themselves in the feature, this is especially important during drought-like conditions. Proper tree pruning is also important throughout the life of the tree, but especially during the early life stages of trees to help limit the potential for detrimental deformations or growth habits. This will help reduce costs as the tree matures and attempts at correcting improper growth, or replacement of the tree entirely becomes more costly. Staff involved in inspection and maintenance of these features should be experienced with the designated planting plan, plant species identification, and weed removal and control methodologies enacted by the municipality.

*'''Irrigation System''': Maintenance or replacement of these system components shall take place as required, meanwhile winterizing watering systems to prevent damage shall take place twice a year (in the Spring and Fall). To limit excess salt impacts in the feature flushing and/or leaching excess sodium in the soil should be done annually in the spring by fully saturating the passive irrigation system with water.

*'''Soil / Growing Medium''': Testing of soil to determine its structure, organic matter and confirm microbial level counts are satisfactory for selected vegetation will take place at installation and during performance diagnostic intervals. Whereas organic fertilizing and soil amendments recommended by testing will be done on an as-need basis.
