Are these curbside trees? Are they in a tree lawn or a pavement cut-out or...?</div><div><br></div><div>One possibility to expand the rooting area for newly planted trees, especially if there is open landscape on the other side of the paved area, is to install CU soil or the Amsterdam soil mix underneath the pavement. This would provide additional rootable area as a best case if there was open landscape on the other side of the pavement or, worst case just to expand access to non-permeable areas.</div><div><br></div><div>As to tree selection, it would have to address the issues that you have mentioned - exposure to de-icing salts and an ability to tolerate pollution and droughty conditions. There are extensive lists that offer possibilities. Planting trees that cannot tolerate these classic urban situations is not acceptable.</div><div><br></div><div>As to infrastructure projects and private development that impact trees, please see my separate reply to Michelle.</div><div><br></div><div>Naomi<br><div><div>On Jan 16, 2017, at 3:37 PM, "Courtemanche, Jill via CANUFNET" <<a href="mailto:canufnet@list.web.net">canufnet@list.web.net</a>> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div lang="EN-CA" link="blue" vlink="purple" style="font-family: Helvetica; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div class="WordSection1" style="page: WordSection1; "><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="font-size: 12pt; font-family: 'Arial Unicode MS', sans-serif; color: rgb(8, 1, 155); ">Michelle you are right to be concerned; in Ottawa we have similar bylaws prohibiting the removal of mature trees for development, but there are many instances of “oops, sorry”. I live in the downtown core and five years ago sewers were replaced on my street. Now, what was a perfectly healthy 83 year old maple on the City part of my lawn has been declared unsalvageable, I surmise because of damage to the roots. We are losing mature trees in the core either from similar causes, or storms which bring down trees weakened by salt, pollution, or drought. My concern now is that the trees being planted to replace mature ones don’t seem able to survive. Does anyone on the list have encouraging results from new trees planted in reconstructed streets, where the ground cover is asphalt/brick/cement?<o:p></o:p></span></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="font-size: 12pt; font-family: 'Arial Unicode MS', sans-serif; color: rgb(8, 1, 155); "> </span></div><div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><b><i><span style="font-size: 13.5pt; font-family: 'Monotype Corsiva'; color: navy; ">Jill Courtemanche<span class="Apple-converted-space"> </span></span></i></b><b><i><span style="font-size: 10pt; font-family: 'Monotype Corsiva'; color: navy; ">R.N./I</span></i></b><b><span style="font-size: 10pt; font-family: 'Monotype Corsiva'; color: navy; ">.A.

Saskatoon is currently seeing several large building projects and homes being built in established neighbourhoods where the work site is surrounded by large valuable City trees. We currently have a City Council policy in place that provide Urban Forestry with direction related to tree protection. As part of this policy we do not remove large (>15cm” diameter) healthy trees for development. However we are finding ourselves in a difficult position of attempting to work with construction companies hired to build what does not reasonably allow for preservation or protection of the existing tree(s). In some cases the building footprint requires excavation that will result in ~40%-50% root removal. Often the damage is done on the private property side when our City trees are close to property lines or in some cases straddle property lines (funny how tree roots just don’t respect property lines).<o:p></o:p></span></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="font-size: 12pt; font-family: Arial, sans-serif; "> </span></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="font-size: 12pt; font-family: Arial, sans-serif; ">I know there are several cities that have tree protection bylaws and some also protect private trees.

I’d also like to know if anyone can share their experience or views (what has worked and what hasn’t worked) with existing Bylaw or policies.<o:p></o:p></span></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="font-size: 12pt; font-family: Arial, sans-serif; "> </span></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="font-size: 12pt; font-family: Arial, sans-serif; ">Thanks, <o:p></o:p></span></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="font-size: 12pt; font-family: Arial, sans-serif; "> <o:p></o:p></span></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="font-size: 12pt; font-family: Arial, sans-serif; "> </span></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="font-family: Arial, sans-serif; ">Michelle Chartier<o:p></o:p></span></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="font-family: Arial, sans-serif; ">City of Saskatoon<o:p></o:p></span></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="font-family: Arial, sans-serif; ">Community Services, Parks Division<o:p></o:p></span></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="font-family: Arial, sans-serif; ">Superintendent - Urban Forestry/Pest Management<o:p></o:p></span></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="font-family: Arial, sans-serif; ">Ph: 306.975-2537 Fax: 306.975.3034<o:p></o:p></span></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="font-family: Arial, sans-serif; "><a href="mailto:michelle.chartier@saskatoon.ca" style="color: purple; text-decoration: underline; ">michelle.chartier@saskatoon.ca</a><o:p></o:p></span></div></div><p>This e-mail originates from the City of Ottawa e-mail system.
