Nadine Turpin asks the City Councillor, Mayor Candidates

Good infrastructure is very important to any city. The roads in Kamloops are noticeably in very poor condition, specifically on the south shore including Valleyview drive. Patching the roads is not a viable long term solution. Can you advise what your role will be in advocating for better roadways in Kamloops? What is the city’s plan for resurfacing and improving our road ways? Thank you.

William James Turnbull

The Transportation Master Plan is the city guide. It ranks projects in order of priority. One potential project that might save Valleyview roads from unnecessary traffic wear is this one: "... Valleyview bypass, as identified by the Province, on the bench lands between Valleyview and Juniper Ridge. The City will continue to work with the Province to understand the need for additional capacity improvements throughout the Southeast Sector. …" - Prepared by Urban Systems Ltd.

Thank you for your question. I too have been concerned about how we are maintaining our roads. Here's some ideas that I want to look at.
1. Perpetual pavements: Perpetual pavements are designed to last around 50 years, compared to 20 years for conventional pavements. Durability is due to the components of superior-performing asphalts and the ability to model and analyze road systems before construction. Pavement cracking occurs when the tensile strength at the bottom of the asphalt exceeds the limit. So the trick with perpetual pavement is to design it from the bottom up.
Hamilton, On, constructed designed the first municipal perpetual pavement in Canada, the Red Hill Valley Parkway in 2007. The bottom layer is a specially designed mix packed with asphalt cement that is basically indestructible, and therefore highly resistant to cracking. The middle and top layers are made of high-quality Superpave asphalt mixes that resist rutting, cracking and wear. We expect pavement to start to breakdown, hopefully minimally, from day one of use. But if it’s a perpetual pavement, nothing will happen at the bottom and the majority of the pavement remains sound. Deterioration will occur at the top, but it’s easy to fix and should only require maintenance every 20 years or so. Because it only involves milling and replacing the surface, it can be done overnight. The costs may be too expensive for low-traffic-volume roads, perpetual pavements are a good option for major roadways. This is something we could investigate.

2. We need to clear the roads of snow better to reduce the freeze and thaw cracking that causes road to break down into potholes. Leaving snow banks that block storm sewer drains along our roads is a bad idea. We need to use front blades on our snow plows because it is way more effective and efficient at clearing snow than a belly blade is. Further we need to have a city road clearing plan that eliminates vehicles from streets overnight so that the roads can be cleared to the curbs easier. Most cities have parking bylaws that restrict street parking during snow periods, we should too.

Last thought. Lets use permeable concrete for parking lots and sidewalks. Here's a link to a youtube video that explains this technology really well. Have a look.

I will advocate for creative, innovative best practices that save us time, money and frustration as a city councilor. Thank you for your question. Please get out and vote on October 20th.
