MISSION STATEMENT

TO ASSIST IN DEVELOPING AND PROMOTING THE PLANNING, CARE, AND MANAGEMENT OF AN ATTRACTIVE, ENVIRONMENTALLY APPROPRIATE AND SUSTAINABLE URBAN FOREST WITHIN THE CITY OF FOLSOM.

The City Arborist is a member of the Community Development Department and is responsible for:

The administration and enforcement of the City of Folsom Tree Preservation Ordinance.

The review of proposed private and public development projects in regards to potential impacts to existing trees on development sites.

The review of proposed  private and public development projects in regards to the creation of new urban forestry resources such as commercial landscapes, streetscapes, and parks.

The monitoring and care of Landmark Trees

In addition, the City Arborist assists the Public Works Department, Landscape and Lighting Districts, and the Parks and Recreation Department in planning and maintaining landscapes through the city.


WINTER TIPS FOR TREES
A few winter tips to keep your trees healthy and safe for next year:

Inspect!  Winter, when most trees are deciduous, is the ideal time to inspect your trees for any sign of structural problems that might lead to branch or trunk failures. Check your trees from the ground up.  Look for narrowly attached limbs, extra-heavy branches, cracks, cavities, loose bark, mushrooms and conks.  If you discover anything that might be suspicious, consider contacting a qualified arborist to conduct a full assessment.

Prune!  Winter is the best time to perform most pruning.  Young shade trees should be trained to a strong and dominant single central leader.  For most trees, more than one leader can lead to structural problems late.  If your tree has more than one central leader, select the strongest and best placed and remove the others.  Leave lower branches attached as long as possible, since they are providing much needed nutrients and help build trunk girth.  Larger trees are best left to a professional arborist.  Never allow a tree to be topped!

Mulch!  Gather up all those pesky leaves that landed in your garden last fall and put them to good use.  Add them to your compost pile and use them in spring as a soil conditioner or surface mulch. Nothing is better than mulching and incorporating organic matter to build good soil!

Plant! Winter is one of the best times of the year to plant new trees.  Trees planted now will have a better chance to adapt, and will require less care and irrigation in the hot summer months.  Many nurseries have their best tree selection in the winter, including bare-root and ball-and-burlap stock.

Pest Control!  Many common insect problems can be more easily treated in winter.  Broad-spectrum, low impact sprays such as dormant oils can control scales and many other insects without the ramifications of using other, less environmentally friendly compounds.  Certain pests, including many that cause "honeydew" to drip from your trees during the summer, should be treated now with systemically acting compounds.  These are usually applied to the soil rather than being sprayed on to the tree.  Remember to always follow label directions or consult with a professional.

FAST TREE FACTS:

100 trees remove 5 tons of carbon dioxide a year.

100 trees remove 1,000 lbs of pollutants a year, including 400 lbs. of ozone and 300 lbs. of particulates.

100 mature trees catch about 100,000 gallons of rainwater per year.

Strategically placed trees can save up to 30% of air conditioning and 10-25% winter heating costs.

Large specimen trees can add as much as 10% to property values.

Consumers spend more time and 12% more for goods in tree-lined commercial districts.

ANSWERS TO SOME FREQUENTLY ASKED QUESTIONS 

Why are trees protected?

Trees add scientifically measurable  benefits to our neighborhoods.  Trees offer us energy savings because of the shade they provide. They reduce storm water runoff and soil erosion by intercepting rainfall.  Trees increase air quality by absorbing pollutants and by releasing oxygen into our atmosphere.  Trees preserve wildlife habitat, enhance property values and provide a sense of identity and tradition in our neighborhoods.  In addition, trees add to the quality of our lives by beautifying  our community.  In particular, our native oaks are uniquely suited to our soils and environment, offering particular pleasure  through their stunning architecture.

Many of the native oaks in Folsom date back hundreds of years, and are historically significant.  Some of these trees, which still exist in our own backyards and public areas, were the source of food, tools, heat and shelter for the Native Americans that preceded our civilization.  Other trees, especially in the Historic District, were planted by some of Folsom's earliest settlers. The City Council has determined that such a valuable resource merits protections.  This protection is clearly stated in the Tree Preservation Ordinance within the Folsom Municipal Code.

What trees are considered protected?
Protected trees under the Tree Preservation Ordinance include native oak trees.  In our region, blue oaks (Quercus douglassi), interior live oaks (Quercus wislizenni), and valley oaks (Quercus lobata) are the most common.  Natural hybrids of these trees are also protected.

Other protected trees include landmark trees, as designated by the City Council, and street trees.  Street trees are trees growing within 12.5 feet of a public right-of-way, and are contained in a master tree list of desirable species for the City of Folsom.

In order to be considered a protected, the tree must have a truck diameter, measured at 4.5 feet above natural grade, of at least 6 inches.  If a tree has multiple trunks and no trucks over 6 inches in diameter, then it must have an aggregate diameter of at least 20 inches to be considered protected by the City ordinance.

When do I need a tree permit?
In general, a tree permit is required if a native oak tree, landmark tree, or a protected street tree is present on a site which will be developed or redevelopment, or if improvements such as swimming pools, building additions, accessory structures, or retaining walls are added to an already developed site.  If protected trees exist on a site where work will disturb the natural topography, even if the activity is not directly under or near the tree, a permit is likely to be required.

Removal of protected trees, including dead trees, requires a tree permit.  Any pruning that substantially modifies the shape of the tree, such as removal of major branches or trunks of multiple trunk trees, will require a tree permit.  Exceptions to this rule are made for emergency situations and for utility companies engaging in routine maintenance of overhead wires.

Most minor pruning, such as the removal of dead branches, moderate weight reduction at the ends of branches, and pruning to provide roof clearance will not require a tree permit.  In most cases, if less than 20 percent of the canopy is removed and work is confined to the outer one-third of the canopy, a tree permit is not required.  Tree topping is not considered minor pruning, and is not considered appropriate tree care, as it creates an increased need for maintenance and greatly increases the potential for hazards.

Are there fees associated with tree removal for building
The Tree Preservation Ordinance requires that the removal of protected trees be mitigated.  Mitigation can be in the form of replacement plantings or the payment of in-lieu fees.  Replacement plantings are usually required to be of the same species as the trees that were removed.  In-lieu fees are based on the location of the tree on the lot and the diameter of the trunk and are set by the City Council.  In-lieu fees are deposited in a special fund restricted to new tree planting, tree replacement, or to obtain or enhance other community forest assets.

How do I obtain a tree permit?

BUILDING WITH TREES

If you are planning to build a home or other structure on a site that contains protected trees, you will be asked to provide certain information.  Most applications will require that a tree inventory by an accredited arborist be prepared and provided to the planning and engineering staff.  Trees must be located horizontally and vertically, and trunk locations and exclusion boundaries for root and truck protection indicated on the grading or site plan.  Off-site protected trees which overhang the lot or that might be affected by access, lot grading, or other activity should also be included.  Staff will use this information to evaluate whether tree removal or encroachment into exclusion areas is necessary, how to best mitigate any potential damage, and whether other reasonable design options exist that might preserve trees.  The goal of these tree preservation efforts is ultimately to add value to the property and to conserve environmental, and often historical, resources.  Links to practical information about protecting trees during construction can be found at the top of the page.
