Request for a 40 Kilometre Per Hour Speed Limit on
Amberjack Boulevard - Ward 15 - Scarborough City Centre
The Scarborough Community Council recommends the adoption of the following report (May 13, 1998)
from the Director of Road and Traffic Services, Scarborough:
Purpose:
To address the need for a 40 kilometre per hour speed limit on Amberjack Boulevard south from Brimorton
Drive to Bellamy Road North.
Funding Sources Financial Implications and Impact Statement:
The $500.00 (approximate) funds associated with the installation of the speed limit signs are available in the
Road and Traffic Services 1998 Budget, Account No. 20000-70200-72240.
Recommendations:
It is recommended that:
(1)the 40 kilometre per hour speed limit identified in Appendix 1 of this report be rescinded;
(2)the 40 kilometre per hour speed limit identified in Appendix 2 of this report be adopted; and
(3)the appropriate by-laws be amended accordingly.
Council Reference/Background/History:
Road and Traffic Services was requested by Councillor Duguid to investigate Amberjack Boulevard, south of
Brimorton Drive, for a 40 kilometre per hour speed limit.
Discussion:
Amberjack Boulevard is a residential road that provides access to Bellamy Road North both north and south of
Brimorton Drive. The section north of Brimorton Drive is posted with a 40 kilometre per hour speed limit,
while south of Brimorton Drive the speed limit is 50 kilometres per hour.
40 Kilometre Per Hour Speed Limit Warrant:
The justification for the introduction of a 40 kilometre per hour speed limit on a roadway in the former City of
Scarborough is based on a technical warrant established by Road and Traffic Services, and adopted by the
former Scarborough Council. Amberjack Boulevard meets the necessary requirements for a 40 kilometre per
hour speed limit on this roadway based on the following criteria:
-traffic volume
-speed characteristics
-pavement width
-minimum distance between controls
-horizontal control curve
Speed Study:
Automatic 24-hour speed studies conducted on Wednesday, April 1, 1998 and Tuesday, April 7, 1998 on
Amberjack Boulevard, east and west of Daventry Road respectively, are summarized as follows:

Collision History:
A review of the collision history on Amberjack Boulevard, south of Brimorton Drive, reveals three reported
collisions over the past three years, January 1, 1994 to December 31, 1996. Two collisions occurred in 1995
and one in 1994. The only incident of excessive speeding occurred in the 1994 collision involving an impaired
motorist driving at 70 kilometres per hour. Given the nature of this collision, further analysis is not warranted
at this time.
Conclusions:
Based on the fulfilment of the 40 Kilometre Per Hour Speed Limit Warrant, a reduced speed limit is
recommended on Amberjack Boulevard. By installing this speed limit south of Brimorton Drive, the speed
limit will now be consistent for the entire length of Amberjack Boulevard.
