Back Sloping Driveway - 632 Glengrove Avenue West -
North York Spadina
The North York Community Council recommends the adoption of the following report (June 18, 1998) from the
Director of Roads and Sidewalk Operations, Works and Emergency Services, North York Civic Centre:
Purpose:
The property owner is proposing to construct an addition to his home including a below grade garage. He has requested
that the standard 2% driveway slope commence at 1.8m (6 ft.) from the curb and from this point slope down to the curb
and slope down to the garage at a maximum of 10%. Presently, 2% driveway slopes are to commence at the property line
approximately 6.1 m (20 ft.) from the curb.
Source of Funds:
All costs to construct the driveway are to be covered by the property owner.
Recommendation:
It is recommended that the driveway slope commence as close as possible to the property line. This would prevent
surface drainage from the road entering onto private property and would provide proper cover to the underground utilities
such as the watermain and that the appropriate City Officials be authorized and directed to take the necessary action to
give effect thereto.
Council Reference:
Council Report No. 4, dated February 23, 1993 received and adopted by Council on March 10, 1993 states that:
"Elevations at the property line fronting the street should be such that the average slope down to the top of the roadway
curb should be between 2% to 6%."
North York Zoning By-law No. 32892 states: "5 (c) Subject to (b), for a single family dwelling on a lot in any R-A, R-R,
R1, R2, R3, R4, R5, R6 or R7 zone where the lot frontage is 13.7 metres or less the maximum slope down of a driveway
shall not exceed (10%) as measured from the property line, and the downward slope of the driveway shall begin from the
owner's side of the property line."
Comments and Discussions:
There is an existing 300mm watermain that runs across the proposed driveway at a distance of approximately 5m (15 ft.)
from the curb. The proposed location of the back slope will result in the insulation of ground cover over the watermain to
be reduced to 1.3m (4.3 ft.) from the existing 1.6m (5.2 ft.). Discussions with the Water and Sewer Section were that the
1.3m (4.3 ft.) cover over the watermain will still be adequate to prevent freezing.
Conclusions:
The proposed location of the downward slope will be contrary to Council's policy and North York Zoning By-law No.
32892 that permits the slope to begin at the property line. The proposal does however provide the correct slope of 2% on
City property and no more than a 10% maximum slope on the private portion. The Water and Sewer Section of this
Department have determined that a 1.3m (4.3 ft.) cover over the watermain will be sufficient to prevent freezing provided
that the existing watermain is at a present depth of 1.6m (5.2 ft.) and that no service connections are affected.
