The Street Services Section is responsible for planting and maintaining approximately 20,000 trees within the public right-of-way and in City parks.Tree Planting on Arbor Day

The City of San Leandro has been named a Tree City USA by the National Arbor Day Foundation for the past thirteen years. Tree Cities must demonstrate a commitment to plant and care for community forests. In 2009, the City earned the prestigious Growth Award for the fourth consecutive year. The award recognizes environmental improvement and higher levels of tree care in Tree City USA communities.

Each year in April, the City celebrates Arbor Day by issuing a proclamation and planting a tree in a City park.

 

The Benefits of City Street Trees

City trees often serve several architectural and engineering functions. They provide privacy, emphasize views, or screen out objectionable views. They reduce glare and reflection. They direct pedestrian traffic. They provide social, environmental and economic benefits to the community.

Trees alter the environment by moderating climate, improving air quality, conserving water, and harboring wildlife. Climate control is obtained by moderating the effects of sun, wind, and rain. Radiant energy from the sun is absorbed or deflected by leaves on deciduous trees in the summer and is only filtered by branches of deciduous trees in winter.  Trees intercept rain water, store some of it, and reduce storm runoff and the possibility of flooding.

Dew and frost are less common under trees because less radiant energy is released from the soil in those areas at night. Temperature in the vicinity of trees is cooler than that away from trees. By using trees in the cities, we are able to moderate the heat-island effect caused by pavement and buildings in commercial areas.

Leaves filter the air we breathe by removing dust and other particulates.  Leaves absorb carbon dioxide from the air to form carbohydrates that are used in the plant’s structure and function. In this process, leaves also absorb other air pollutants—such as ozone, carbon monoxide, and sulfur dioxide—and give off oxygen.

By planting trees, we return to a more natural, less artificial environment. Birds and other wildlife are attracted to the area. The natural cycles of plant growth, reproduction, and decomposition are again present, both above and below ground. Natural harmony is restored to the urban environment.

The economic benefits of trees can be both direct and indirect. Direct economic benefits are usually associated with energy costs. Air-conditioning costs are lower in a tree-shaded home. Heating costs are reduced when a home has a windbreak. Trees are a wise investment of funds because landscaped homes are more valuable than nonlandscaped homes. The savings in energy costs and the increase in property value directly benefit each home owner.

The indirect economic benefits to the community or region are even greater. Lowered electricity bills are paid by customers when power companies are able to use less water in their cooling towers, build fewer new facilities to meet peak demands, use reduced amounts of fossil fuel in their furnaces, and use fewer measures to control air pollution. Communities also can save money if fewer facilities must be built to control storm water in the region.
