[CANUFNET] Soil volume requirements in subdivision agreements

[brettwoodman at yahoo.com]

Phillip, 
That is a very real concern. Lawn areas in yards and parks are required to have topsoil depths of 200mm vs the 750mm in tree and shrub planting areas.  Effective 2009 Oakville has had topsoil specifications and testing requirements to ensure topsoil quality.

Will there be a requirement for there to actually be soil in the front
yards? The way Oakville and other communities in Southern Ontario are
currently developing there is mostly subsoil and construction rubble etc in
the front yards..it is also usually heavily compacted and poorly drained.

Jim,
Agreed. In North Oakville structural soil is primarily recommended for use
in break-out zones under sidewalks where the required soil volumes cannot be
realized in the boulevard. The break-outs will allow trees to access
front-yard soil volumes.

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.

Shelley,

 

Attached is a draft version of the North Oakville Urban Forest Strategic
Management Plan.  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.

Hi Everyone, 
We are looking to include soil volume requirements in our subdivision
agreements and would like to hear from municipalities that already do so.
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.
