Tree Preservation and Removal

Tree Removal

The County of Santa Clara recognizes the significant value of its tree population.  Trees provide aesthetic and scenic beauty, prevent erosion of topsoil, protect against flood hazards and the risk of landslides, counteract air pollution, and can be valuable historical and community assets.  They provide wind protection, shade, climatic balance, privacy, and wildlife habitat.  In addition, studies have demonstrated that trees increase property values.
