Council wants to know more about fill for White Rose Phase 3 build

·2 min read

Some more information is being requested about the fill to be brought into the site of the next phase of the White Rose subdivision in Dundalk.

Thirty houses, 24 townhouses and 24 (or more) seniors units will be built north of Bradley in Dundalk, east of Todd Crescent, which was an earlier phase of White Rose.

“I am concerned that we don’t know enough about the fill,” said Coun. Dobreen.

Coun. Jason Rice agreed, contrasting it with using fill from licenced pits.

Council decided to defer the approval and ask staff to talk with the Grand River Conservation Authority and to township and county roads departments to gather further information.

Southgate has a fill and site alteration bylaw which lays out the information needed. The item appeared on the agenda with a number of supporting technical papers.

Chief building official Bev Fisher said the engineering reports had been supplied.

The background prepared by Peto MacCallum consulting engineers says the source is the southwest corner of Hwy. 7 and the Interchange Way, Vaughan, very close to the 400, on previously undeveloped land.

It did its own review of an analysis done by another firm in June which was assessing the soil for possible importation to sites in Innisfil. The soil type was reported as a brown, sandy silt.

The Peto MacCallum report’s conclusion was that only part of the site will yield fill suitable for White Rose subdivision – an area of 12,290 metres up to three metres in depth in the south area of the site.

The rest, because of test results exceeding sodium levels, which is usually because of de-icing materials, could only be used in roadways or at a subsurface level, the report concluded.

Peto recommended audit sampling to assure environmental results at a frequency of one sample for 2,000 cubic metres.

The company that would look after testing on arrival is Terra Probe of Brampton, which also does geotechnical work and testing.

The Terra Probe report states that about 3,000 cubic metres of fill material would be required to develop the property according to approved plans.

To meet government regulations, one sample would be required every twentieth load that arrives, Terra Probe said.

Coun. Michael Sherson asked about truck traffic in town. CAO Dave Milliner said to keep traffic away from Main Street in Dundalk, the haul route could be along Glenelg and Grey streets.

A further question was raised by the CAO about whether a more granular material would be better for roadways, and affect drainage. The standard for the subdivision is to equal or improve pre-existing drainage, Mr. Milliner said.

While the request has supplied documentation, the motion was made and passed to defer it to gather more information.
