McKay Road Interchange and Salem / Lockhart Crossing The McKay - - PowerPoint PPT Presentation

McKay Road Interchange and Salem / Lockhart Crossing

• The McKay Road Interchange Class EA has two components:

1. A new MacKay Road Interchange at Highway 400; and 2. A new bridge crossing of Highway 400 at Salem / Lockhart Road.

• The need and justification for these projects (Phases 1 and 2 of

the Municipal Class EA process) was completed as part of the City’s Multi-Modal Active Transportation Master Plan MMATMP (2014) and is being confirmed through ongoing work with the Ministry of Transportation Ontario (MTO).

• The current EA will complete Phase 3 (Design Alternatives) and

Phase 4 (Environmental Study Report) of the Class EA process.

• The design of these components will be integrated with the

planned improvements to Salem / Lockhart Road and McKay Road, east and west of Highway 400.

• The design of the McKay Road Interchange will also be

integrated with MTO’s Highway 400 improvements, which include the current replacement of the McKay Road bridge and future widening of Highway 400. The McKay Road Interchange and Salem / Lockhart Crossing is subject to MTO approval.

List of Studies Undertaken

Study Key Conclusion

Archaeological Assessment Site of significant archeological potential in the northeast quadrant at McKay Road interchange location (Huron-Wendat Village). Drainage and Stormwater Management (SWM) Plan Two SWM ponds will be required at the McKay Road interchange. The SWM plan at both locations will integrate with the drainage management plan of Highway 400 corridor. Natural Environment Lovers Creek Swamp (Provincially Significant Wetland) is located within the vicinity of the Study Area. No Areas of Natural Scientific Interest are present in the vicinity of the Study Area. One watercourse present in study area. Traffic Operations / Analysis To be completed. Traffic data required from ongoing concurrent project Noise Assessment To be completed. Traffic data required from ongoing concurrent project Geotechnical Assessment No geotechnical concerns identified

The potential improvement alternatives were presented at PIC #1. The next step in the EA process is to conduct an assessment and evaluation to compare the improvement alternatives, and identify a technically preferred alternative. The following list details the studies undertaken to provide input into the assessment and evaluation of improvement alternatives for the Salem / Lockhart Road Crossing and the McKay Road Interchange.

Design Alternatives Evaluation

• Design alternatives were developed at both McKay Road Interchange and Salem / Lockhart Road Crossing

locations and were presented at PIC #1. The alternatives have since have undergone a detailed assessment and evaluation to identify the preferred alternatives.

• The assessment and evaluation utilized

four key factor areas within which the evaluation criterion were established.

• Study area constraints that factored

into the decision-making process were detailed at PIC #1.

• The following boards summarize the

results of the assessment and evaluation.

• The detailed results of the evaluation

and the preferred alternatives will be included in the Environmental Study Report with an opportunity for public review at the time of filing.

Salem Road Reservoir & Pumping Station

• City of Barrie’s Infrastructure Master Plan: Water

Storage and Distribution Master Plan (2013) identified an need for a pumping station and reservoir located on Salem Road.

• Water Storage and Distribution Master Plan

(2013) fulfilled the Municipal Class Environmental Assessment (EA) Schedule B for the planning of the water supply system.

• General locations of system storage and pumping

stations originally identified in the Master Plan were selected based on land use, topographic features and systems needs but the locations are conceptual and subject to minor changes due to land availability.

• An assessment of potential reservoir locations

undertaken as part of this assignment considered a range of environmental and technical factors including natural environment, cultural heritage, land use, groundwater etc.

Reservoir Site Alternatives Evaluation

Site 1

• Topography consistent with City of Barrie pressure zone
• perating levels, consistent with water and sewer servicing
• Property size: 4.1 ha
• Good access and adjacent to compatible land use –

industrial / commercial

• Site is conducive to future expansion to service growth

Site 2

• Topography consistent with City of Barrie pressure zone
• perating levels, but offers less construction flexibility
• Property size: 3.5 ha
• Good opportunity for future expansion
• Requires intrusion into more environmentally sensitive

(i.e., forested) lands Site 3

• Topography consistent with City of Barrie pressure zone
• perating levels, but is only compatible with On Ground

Cylindrical Reservoirs

• Property size: 1.3 ha
• Limited to relatively small parcel of land east of Hwy 400
• Limited access and adjacent to strict transportation and

utility corridors

• Limited to no capacity for expansion

Preferred Site Selection

Site 1

• Good access and adjacent to compatible land use
• Easily accessible to watermain and sanitary trunk main along Salem Road
• Greatest opportunity for future expansion
• Site design and landscaping can be optimized to maximize compatibility with

adjacent development adding versatility and net benefit to the area

Sub-Grade Reservoir Option

• Buried, cast-in-place concrete reservoir

On-Grade Reservoir Option

• Pre-stressed concrete design and construction
• Glass-fused-to-steel design and construction

Reservoir Design Options: Sub-Grade versus On-Grade Reservoir

Criteria Selection Sub-Grade Reservoir On-Grade Reservoir

Operations and Maintenance Conducive to current operational control and integration with the existing water supply and distribution system. Conducive to current operational control and integration with the existing water supply and distribution system. Operations and Maintenance Costs Similar. Similar. Capital Cost Capital costs are significantly greater:

• Excavation and shoring requirements.
• Cast-in-place concrete construction.

Capital costs are significantly less:

• Grading.
• Pre-cast / pre-stressed concrete or glass

fused-to-steel.

• Both options are pre-fabricated off-site

and delivered to site for assembly. Construction Duration (Estimated) 18 – 24 months. 12 – 16 months.

Reservoir Site - Next Steps

• 1. Finalize conceptual reservoir design
• 2. Completion of life cycle cost analysis to finalize

preferred reservoir design option

• Preliminary preference is Site 1, On-Grade reservoir
• 3. Recommended reservoir location will be subject

to review and permitting by regulatory agencies, including Lake Simcoe Region Conservation Authority

• 4. Geotechnical investigation to confirm suitability

for construction
