I believe that the reason for this is that the construction standards that were in place decades ago (between neighborhood establishment and the time the sidewalk was last replaced) allowed for the construction of sidewalks on top of organic soil. So, in most cases, the trees had little challenge accessing soil beyond the boulevard. <o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>However, new construction standards include a gravel base and mechanical compaction under sidewalks. Also, greenfield construction is not what it used to be. Nowadays developers remove all of the precious topsoil from the land before building a new subdivision, then bring back enough topsoil to support the new sod. In these cases, regardless of the sidewalk design (mono or seperate) the trees do not have enough soil volume to support them. We do amend soil volumes with trenches in separate boulevards, but these are trenches in clay with still inadequate soil volumes. So my point is, depending on construction practices and standards, the configuration of the sidewalks in relation to the trees may have less impact on soil growing space than we think. <o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>but I would agree that trees in a more free to grow state, with little or no barriers to quality soil will outperform a tree in restricted growing space, and there will be fewer infrastructure / tree conflicts.

My observation is that trees that are planted in a boulevard behind a monolithic sidewalk (sidewalk up against the curb and planting area next to the property) generally do better. They have access to more soil volume in the front yard, they get more water and the boulevard is tidier since the homeowner treats it like part of their yard. Also fewer issues with roots lifting sidewalks. Some of our staff prefer the separated treed boulevard, for various reasons.
