Staff Report - Approval to Award Design of Millstream Road Roundabout

Background

The City’s long-term plans include construction of a roundabout on Millstream Road at Bear Mountain Parkway. Recent traffic counts in the area indicate that this corridor would benefit from construction of a roundabout here sooner rather than later.

The purpose of this report is to gain Council approval to award the detailed design and estimating for this roundabout and potential look to tender it for construction in 2021.

Commentary

Millstream Road northbound and southbound service a light industrial area located north of Bear Mountain Parkway that is partially in Langford and partially in the Highlands. Millstream Road is the primary corridor to and from this area and therefore the traffic mix here consists of heavier truck traffic as well as residential traffic from the greater Bear Mountain area and the Highlands.

Recent traffic counts in the area indicate that this corridor would benefit from construction of a roundabout here sooner rather than later.

Initially a single lane roundabout can be constructed to accommodate existing traffic. A dual lane roundabout, such as the one located at West Shore Parkway and Langford Parkway, would be required in the future if for example the Western Speedway property were to develop and/or the population keeps increasing in this area.

Staff are seeking to undertake a detailed design for both the interim and ultimate configuration of the roundabout at this location. One reason for doing both an interim and ultimate design is to minimize any

“throw away” work when the ultimate roundabout gets constructed. Additionally, staff wish to confirm if land is needed to accommodate either the interim or the ultimate construction.

Staff obtained an estimate from McElhanney (consulting firm). McElhanney are the City’s roundabout consultant on the Peatt at Brock roundabout where the interim construction for this roundabout is underway right now. In that case McElhanney did both an interim and ultimate design. The design considered the most recent safety recommendations from ICBC resulting in a contributing financial grant from ICBC for the construction of the Peatt at Brock roundabout. Staff anticipate applying for, and being successful for an ICBC grant to contribute toward the cost to construct the Millstream roundabout. This is normally done by completing an ICBC Road Safety Audit, having ICBC staff review the designs and provide any feedback as necessary.

McElhanney staff have successfully completed other large roundabouts on the lower island, one example being the double roundabout in the City of Duncan. In addition, the McElhanney team routinely facilitates ICBC roundabout workshops across BC, including one in Victoria that many of our Langford staff attended last year.

Financial Implications

The cost to undertake data collection for both the interim and ultimate design, complete the interim and ultimate design and prepare tender documents is estimated at $86,668 plus GST. Staff are proposing to fund this from the City’s Road DCC program budget. There are sufficient funds in this budget to proceed now (in 2020) with this design work. This would best enable staff to tender this job in early January for consideration to construct in 2021 with the City’s 2021 budget discussions.

Legal Implications

None noted.

Options

That Council:

1. Award the Consulting Engineering Services for the design of the Millstream Road at Bear Mountain Parkway roundabout to McElhanney for the estimated cost of $86,668 plus GST and fund this from the City’s Road Development Cost Charge program;

OR

2. Not award this contract at this time.
