Ancillary Facility Construction 163

Ancillary facility pipes will be installed beneath road travel lanes, using cut and cover methods. Public safety effects of installing pipes in roadways are primarily associated with operation of heavy equipment and the presence of open trenches. Flag persons will be employed during the day to manage vehicles and pedestrians near the work sites. Barriers or flagging will be installed to alert people to the presence of open trenches.

Construction of ancillary facilities will disrupt vehicular traffic on affected routes. The extent and severity of disruption will be a function of the traffic volumes and available opportunities to keep some lanes open or to reroute traffic. The roads potentially affected by the construction of ancillary facilities are two-lane. This assessment assumes that one lane could remain open and alternating directions of traffic utilise the remaining lane.

5.10.3.1 Macaulay Point to McLoughlin Point

Potential Impact: Construction of the ancillary facilities connecting Macaulay Point and McLoughlin Point may result in increases in traffic congestion.

Construction of the underground utilities will be installed in a trench along Peters Street and Victoria View Road for approximately 680 m. The route is located on DND property and has low traffic volumes.

The road distances and the planned route for the 1,500 mm forcemain between the Macaulay Point and McLoughlin Point facilities are presented in Table 35. All roads are local two-lane roads with low traffic volumes.

Mitigation measures: Standard procedures for managing vehicular traffic in a construction zone will be implemented, keeping one lane open to alternating directions of traffic. Ancillary pipe construction should be restricted to single blocks at a time and, to the extent feasible, scheduled outside of peak periods of vehicular activity.

Increases in traffic will be local, short-term in duration and continuous during the construction period. Only small volumes of traffic will be affected, so the impact is considered low in magnitude. One-way alternating traffic will be permitted and there will be no residual impact, resulting in a rating of less than significant.

5.10.3.2 Clover Point

Potential Impact: Construction of the ancillary facilities connecting Currie Road to Clover Point may increase traffic congestion.

The construction of the ancillary facilities connecting the Currie Road pump station to the Clover Point pump station may result in temporary access disruptions to local residents. Traffic management measures will be applied during construction.

Potential Impact: Construction of the ancillary facilities connecting Clover Point and McLoughlin Point may increase traffic congestion.

A 1,200 mm forcemain will be installed from the Clover Point facility to the McLoughlin Point facility. The conveyance pipeline will be installed in the grassy area south of the boulevard to align with a proposed City of Victoria bike path or in a trench along Dallas Road from Clover Point to Ogden Point at the James Bay Anglers boat ramp (3,300 m), and continue via HDD tunnel (850 m) beneath Victoria Harbour to McLoughlin Point.

In most places, Dallas Road is a fairly wide road and has areas assigned to angle parking, so it is assumed that one lane could remain open and alternating directions of traffic utilise the remaining lane. Dallas Road is busy during peak tourist season, is a primary link to the regional helicopter and cruise ship terminals. The road is one of Victoria’s most scenic routes and provides a linear connection to parks for a variety of transportation modes, and constitutes a portion of the popular cycling Seaside Touring Route. Bicycles, tour buses, horse-drawn carriages and many pedestrians use Dallas Road. With the volumes and types of traffic that will be affected on Dallas Road, traffic effects during construction of conveyance pipelines from Clover Point to McLoughlin Point during peak use period are considered local, short-term, reversible, high in magnitude, and significant.

Mitigation measures: The volume and nature of traffic on Dallas Road will require enhance procedures for managing vehicular traffic in the construction zone. Typically one lane will remain open to alternating directions of traffic. Flag persons will be employed during the day to manage vehicles and pedestrians near the work sites. Barriers or flagging will be installed to alert people to the presence of open trenches. Construction should be restricted to single blocks at a time. Measures to maintain safe cycling will be required. Access to high-density apartments along Dallas Road will need to be maintained, as will access to Ogden Point and the helicopter terminal.

Traffic impacts can be reduced by scheduling the ancillary pipeline construction along Dallas Road outside the peak use period, preferably in the late fall, winter, or early spring.

If enhanced mitigation is implemented, and a traffic lane remains open at all times, impacts of constructing the conveyance pipe from Clover Point to McLoughlin Point will be local, short-term, reversible, moderate in magnitude and assessed to be less than significant.

5.10.3.3 Arbutus Road

Potential Impact: Construction of the Arbutus Road ancillary facilities connecting the attenuation tank to existing sewer infrastructure may increase traffic congestion.

The ancillary pipes at Arbutus Road are located within the property boundaries. As such, few impacts on traffic are anticipated during construction. Standard traffic management measures will be applied during delivery of pipe equipment and installation of the materials.

Mitigation measures: No special mitigation measures are necessary.

The impact on traffic associated with the construction of the ancillary facilities at Arbutus Road will be local, short-term, reversible, low magnitude and less than significant.

Potential Impact: Construction of the proposed roadworks on Arbutus Road may increase traffic congestion.

Construction required to upgrade Arbutus road with a bike lane and separated sidewalk will temporarily disturb traffic flows on Arbutus Road. Traffic management measures will be applied during construction.

Mitigation measures: No special mitigation measures are necessary.

The impact on traffic associated with road upgrades on Arbutus Road will be local, short-term, reversible, low magnitude and less than significant.

5.10.3.4 Craigflower

Potential Impact: Construction of the Craigflower ancillaries may increase traffic congestion.

The ancillary pipes associated with the Craigflower site are located in the property boundaries, on Shoreline School grounds and beneath Portage Inlet. Standard traffic management measures will be applied during delivery of pipe equipment and installation of the materials.

Mitigation measures: No special mitigation measures are necessary.

The impact on traffic associated with the construction of the ancillaries at Craigflower will be local, short-term, reversible, low magnitude and less than significant.
