- Underground utilities present: In the case of sewer lines, storm drains or electric lines, consult your utility agency.
- Area too small or narrow: Grass strips must be at least 4 feet wide, preferably 6 feet, before trees are installed.
- Care or pedestrian safety jeopardized: Trees reduce visibility. Consider future size of tree, as well as current (especially with evergreen trees).
- Overhead wires present: Wires limit ultimate tree height, thus limiting the species of tree that can be used.
- Poor site conditions: Poor soil, old roadbeds, salt and other physical factors restrict or eliminate landscaping potential in some areas.
- Non County-controlled locations: Planting on state or federal roads or rights of way requires permission from the controlling agency. Added requirements for these areas usually delay project installment by at least one year.
- Planned construction: Planting can not take place until any planned street widening; sidewalk, curb and gutter construction; or sewer work is complete.
- Busy roadway: It is safer to put trees on lightly traveled residential streets, rather than heavy traffic areas.
- Damage-prone areas: Areas subject to frequent vehicular accidents or excessive vandalism are usually not landscaped.
- Required maintenance unavailable: Many projects are curbed or postponed due to limited availability of maintenance staff and funds to provide proper care.
