About Trees

The Right Place

Planting a tree in the right place can greatly impact your home and neighborhood.

Below you will find information to help you chose where to plant a tree so that you can get the greatest benefits for your needs. Click the topic areas below to learn more...

Maximize summer cooling

"West is Best" - Planting trees that drop their leaves in the winter (i.e. deciduous trees) on the west side of your home will provide the greatest summer cooling benefits; the second best place is on the east side. The trees will block the sun from coming into your windows and heating the air inside, which causes you to use energy to run fans and air conditioning to cool the house. Plant the tree at least half the mature spread of the tree canopy from the house. For example, if you chose a tree that has a mature spread of 40' the tree should be planted at least 20' away from the structure. You might think that planting a tree on the south side would provide even more shade; however, trees on the south side can block the sun from heating your home in the winter even though the leaves are absent.  Back to top.

Maximize winter heating

Plant evergreen trees to the north and northwest sides of your house to block cold winter winds. Avoid planting trees on the south side, which can block the warming sun in the late day. Remember that many evergreens grow very large. Be sure to plant them so that they have plenty of room to reach their mature size and avoid future conflicts.  Back to top.

Reduce air temperatures

Cool down the neighborhood! Trees shade pavement thereby reducing the overall temperature of a neighborhood. In many cases air temperatures can be reduced by as much as 10 degrees! Plant deciduous trees to shade driveways, sidewalks and streets. Avoid planting evergreen trees that will shade pavement in the winter and prevent snow and ice from melting.  Back to top.

Solar access

Think you have to choose between a tree and solar collectors? Not true! Most experts recommend placing solar collectors on the south-facing portion of the roof. Planting trees that shade the south side of a home is not recommended as they will block the warming rays of the sun during the winter months when you most need passive solar heating. On the other hand, there are tree species that have low mature heights that will stay well below rooftop solar collectors.  Back to top.

Planting with power lines

Safety should be the top priority for everyone, even for trees. Trees and power lines should be taken very seriously, so plan ahead when placing new trees. Click here to learn more about planting trees close to power lines and transformers.  Back to top.

The Utility Notification Center of Colorado (UNCC) is a non-profit, non-governmental organization. It is funded by its member facility owners and operators. Its purpose is to act as a messaging Center between excavators and underground facility operators for locate requests when excavation activity is required. UNCC is the statewide messaging Center for the State of Colorado only.

Colorado SB 93-155 requires that anyone that engages in any type of excavation must provide advance notice to the underground facility owners. The notice must be at least two business days, not including the day of the call, prior to any excavation. To process normal locate requests, calls must be made to UNCC, Monday through Friday, 7:00 am to 5:00 pm, excluding holidays.  Call before you dig.
