Mr. Garrett Donaher, Manager of Transportation was present to discuss the above cited matter and advised that it will be brought forward to Council for a decision at the March 24th Committee of the Whole meeting. Specifically, Council needs to decide on the material to be used for the Kelly's Brook shared use pathway and as such, the opinions of this Committee are being sought.
The feedback heard so far during the public engagement process brought forth the importance of accessibility as well as maintenance considerations, i.e. water flow/runoff near the trail, costs associated with the trail, etc. Upon investigation costs over a 20 year life cycle are in the range of $1 million. The option for asphalt is about 10% over and above that amount.
Co-Chairperson Joby Fleming referenced the discussions held in the working group wherein it was determined that asphalt and concrete were the most preferred materials in terms of accessibility. Members of the Committee expressed overall support for the recommendation to use asphalt material. The following points were outlined also:
- Concerns expressed about the maintenance of the trails to offset safety hazards such as surface deterioration, pavement cracks, potholes, ruts, etc. Staff elaborated on the base pavement structure of a pathway, the components of which allow water to disperse through layers of gravel which offsets contraction and expansion due to freezing and thawing. The engagement page contains extensive information on the geotechnical report and construction scale for the pathways which outlines in great detail various options and specifications.
- Shedding of water off the trail was also referenced and it was suggested that should any weak areas be identified, they should be fortified where necessary. Staff assured that such areas will be identified through the geotechnical report and addressed accordingly. The Committee and Working Group will continue to be consulted as the project unfolds.
- The quality of asphalt was questioned and whether or not there are specifications in place to ensure strength, durability, etc. Staff advised that the standard used around the City will apply, noting that options are limited.
- Should any damage to the pathway occur such as cracks, etc, will these be rectified in a more timely fashion than is currently the case for city streets. Staff advised that a maintenance protocol must be budgeted to rectify such issues.
- Reference was made to the use of alternate materials to asphalt such as recycled plastic that may have more durability. Staff advised that research was conducted on different materials newer to the market which were found to be effective as outlined in the background materials; however, costs were prohibitive.
Councillor Froude who was present during this discussion thanked members for their feedback and advised he would relay the Committee's recommendation to Council.
