[CANUFNET] Soil volume requirements in subdivision agreements

[James Urban]

But when measuring soil it is critical to count the actual soil installed not the structural system that holds up teh pavement.  Structural soil is only 20% soil while Silva cells is 955 soil.  One must measure each system correctly.

It has not yet been adopted by council, but we are working closely with a sub-committee of council and anticipate that it will be approved with some revisions early in the New Year.  Of relevance to your question is that we are requiring a minimum of 15m3 of soil per tree with a depth of 750mm.  Where more than one tree is planted in a single volume of soil, they are allowed to share, so that not every tree requires 15m3. We anticipate revising the wording to read that where possible, without the use of engineered rooting environments (SilvaCells or CU Soil), each volume of soil will be a minimum of 30m3. This proposed standard, while developed for North Oakville will be applied Town-wide.  Let me know if you have any questions.

In particular, we would like to know how these requirements are incorporated into the agreements and how they are being verified and accepted.   We appreciate any help you can provide.
