To:Chairman and Members of the Scarborough Community Council
From:Gary Welsh, Director, Road and Traffic Services, Works and Environment, Scarborough District
Subject:Request for a 40 Kilometre Per Hour Speed Limit on Amberjack Boulevard, Scarborough City Centre
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 proposed 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(1)the 40 kilometre per hour speed limit identified in Appendix 1 of this report be rescinded;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 km/h. 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.
