Trees Forever has developed several guides to help you select trees appropriate to various conditions.
The lists are based on the USDA Plant Hardiness Zones found in Illinois and Iowa (Zones 4-6).
Tree and Utility Line Conflicts
Three different zones of tree planting to consider:
Zone 1 – Directly under utility lines to 20 feet from overhead utility lines:
Use 25’ maximum tree height (ornamental trees)
Read Tree Selection Aid for sites with overhead powerlines
Zone 2 – From 20-50 ft. from overhead utility line:
Use 35’ max. tree height (medium trees)
Zone 3 – 50 ft. and beyond from overhead utility:
No height restrictions on trees (large shade trees)
Read Tree Selection Aid for sites without overhead power lines
