Restoration and Maintenance Works within

Watercourse South of Citation Drive

from Bayberry Crescent to Burbank Drive

(Ward 12 - Seneca Heights)

The Works and Utilities Committee recommends the adoption of the following report (May 25, 1998) from the Commissioner of Works and Emergency Services:

Purpose:

To request $300,000.00 funding for restoration and maintenance works in the watercourse south of Citation Drive from Bayberry Crescent to Burbank Drive.

Source:

From the 1998 Capital Budget Item Sanitary and Storm Sub-Trunk Sewers (North York).

Recommendations:

It is recommended that:

(1)an amount of $300,000.00 be authorized for restoration and maintenance works required within the watercourse (Citation Drive) from Bayberry Crescent to Burbank Drive in North York's easement;

(2)the funding be from the 1998 Capital Budget Item for Sanitary and Storm Sub-Trunk Sewers (North York); and

(3)the appropriate City officials be authorized and directed to take the necessary action to give effect thereto.

Background:

The section of watercourse between Bayberry Crescent and Burbank Drive, parallel to Citation Drive, is in a state where restoration and maintenance repairs are necessary. The length of this watercourse is approximately 340m and is located on an easement in favour of North York. This Department has recently received numerous complaints from residents of hazardous conditions in their rear lots especially during the storm events.

In 1996, the City of North York tendered the construction to restore the upstream section of this watercourse parallel to Citation Drive from Bayview Avenue to Bayberry Crescent. Over the years, the rip-rap work that was placed in the watercourse had collapsed due to age and continuing current action of the storm water. Conditions had deteriorated to the point where it became a hazard and a danger to the houses backing onto the watercourse. The works constructed in 1996 included the stabilization of the creek bank with gabions and armourstone, concreted riverstone channel, rebuilt inlet head wall and re-vegetation.

The Works Department has estimated that it would cost $300,000.00 to restore the watercourse from Bayberry Crescent to Burbank Drive with the same type of construction methods as previously performed on the section of watercourse between Bayview Avenue and Bayberry Crescent. It is proposed to fund this work from the 1998 Budget Item for Sanitary and Storm Sub-Trunk Sewers. There are sufficient funds to carry out the works on the Citation Drive watercourse.

Conclusion:

It is proposed to restore the watercourse parallel to Citation Drive between Bayberry Crescent to Burbank Drive to address local residents' concern of hazardous conditions during storm events. The estimated cost of $300,000.00 is available from the 1998 Capital Budget item for Sanitary and Storm Sub-trunk Sewers (North York).
