<p class="MsoNormal"><span style="mso-fareast-language:EN-US">The manual explores various options (not just soil cells) for effectively integrating trees into urban streetscapes, and also considers questions like maintenance, etc.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="mso-fareast-language:EN-US">You should definitely also invest in a copy of James Urban’s
<i>Up by Roots. </i>It’s from 2008 but I think it’s still the gold standard for these sorts of questions. The DeepRoot blog also has some really great articles; you can spend lots of time getting down various rabbit holes and it’s all good stuff.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="mso-fareast-language:EN-US">As to some of your specific questions – I’ve jotted just a few quick thoughts in your original email below, in bold. Just a starting point. Obviously, addressing a lot of these questions will depend
upon the Town’s budget for the downtown core revitalization project, but investing in getting the tree situation right will certainly pay dividends.<o:p></o:p></span></p>

<p class="MsoNormal">The Town of Whitchurch-Stouffville is looking to redevelop it's down town core. A half kilometer of small commercial shops in a tight busy roadway. It is the main east west access for the busiest and most populated are of the municipality.
We are looking for ways to incorporate trees in the redevelopment. The sidewalk is 3 to 4 meters wide with a 4 lane roadway. The outer 2 lanes are used for parking. <o:p></o:p></p>

<p class="MsoNormal">There are issues with signage. Owners do not want signs covered.
<b>An understandable issue, but business owners should be educated about the increased commercial activity and ‘willingness to spend’ in well-treed commercial districts. Lots of literature out there on the subject. This source (Wolf, 2010) is a little dated
now but is a good summary of the research: <a href="https://depts.washington.edu/hhwb/Print_Economics.html">
https://depts.washington.edu/hhwb/Print_Economics.html</a> (under ‘Retail & Consumer Environments’). Also here is an interesting write-up on the subject:
<a href="https://investfromthegroundup.org/trees-and-sign/">https://investfromthegroundup.org/trees-and-sign/</a> that may offer some ideas (alternative signage, pruning strategies, etc.)

<p class="MsoNormal">Salt issues in the winter and snow clearing of the sidewalks.
<b>Definitely an issue but raised curbs around the planting areas, passive irrigation inlets with seasonal shutoffs (to prevent salt-laden snowmelt from entering the irrigation system), spring flushing, and alternatives to NaCl (expensive but worth it), should
all be considered. Public Works/Transportation (staff and mgmt.) need to get on board that they have to work a bit differently/more carefully around high-value trees; to be successful a major revitalization project like this needs everyone to get on the same
page.<o:p></o:p></b></p>

well!) I think tree guards are ok for young trees as long as they can be taken off/apart when the trees grow large; these help prevent damage from people locking up bikes, etc. (not sure how big an issue that is in W-S, but it’s big in downtown Toronto). Berczy
Park has good examples – they are fairly low, far away from the trees, and can be dismantled when no longer needed. Mulch is obviously your best bet but there can be issues with runoff when it rains. Other options are also available – decomposed granite, resin-bound
aggregate, plantings (great for excluding people from the root zone!), etc.<o:p></o:p></b></p>
