Strategic Vision Element: Where People Choose to Live - A dynamic city with an exceptional quality of life Related Goal: Citizens consistently express high levels of satisfaction with municipal services.

Information
Request for Decision Summary
To provide an update on the Snow Storage Facility to date, remaining work to be completed and the overall costs and budget of the project.

Proposed Motion
That the update on 2020-2022 Corporate Plan initiative CE428.5, Detailed Design and Construction of Snow Dump Site, be received as information.
Background/Analysis
The City of Spruce Grove currently operates a snow storage site within the City.  In 2014 the City identified that additional snow storage capacity was required to meet the City’s needs.  The City identified the sewage lagoon site, located north of Spruce grove adjacent to Century Road, in Parkland County, as the proposed location for the snow storage site. 
 
Traditionally collected snow from City streets would be stockpiled in an undeveloped parcel of land within the City.  However, based on increased awareness of environmental concerns, it was identified that snow sites have the potential to contaminate the local environment.  The particular environmental concern was road salts leaching into the environment.  There is also an increased public perception of the sites being dirty due to the presence of debris that is left within the site once the snow melts. 
 
Based on increased environmental concerns related to snow storage sites in the province, Alberta Environment and Parks published the Snow Disposal Guidelines in 1994.  The Snow Disposal Guidelines outlined the features that permanent snow storage facilities should incorporate, such as an impermeable barrier under the snow pile area, and the melt water pond to collect and control the discharge from the site.  In 2013 the Transportation Association of Canada published the Syntheses of Best Practices for Road Salt Management, which identified additional best management practices for snow storage sites to minimize environmental contamination.
 
In 2014 the City of Spruce Grove retained Associated Engineering to develop a concept for a snow storage site at the City’s existing sanitary lagoon facility.  The City identified the following site requirements:
  • An ultimate site capacity of 1,000,000m3 of snow storage with the intent that the site would be phased over time.
  • Incorporate best management practices which minimize the environmental risks of the site on the surrounding environment.
Based on this direction, a site concept was developed and accepted by the City which included the following features:
  • A snow pad that can provide an ultimate storage capacity of 1,000,000m3 of snow, but developed in phases. 
  • A synthetic liner under the snow pad area and within the melt water pond to provide environmental containment. 
  • A roller compacted concrete surface will be placed within the snow pad area to protect the synthetic liner, and provide all-weather access for equipment.
  • Melt water from the site will be released to Atim Creek.  As Atim Creek has a relatively low flow, the discharge from the site will be modulated to meet the release criteria for the site and the minimize impact to the environment. 
Based on the site concept, the site will be developed over three phases.
 
Detailed Design and Construction of Snow Dump Site CE428.5 as approved in the 2020-2021 Corporate Plan
Phase 1 will include the following:
  • Construction of a site access road and right hand turning lane from Range Road 272 to accommodate site traffic.
  • A 450mm thick clay snow pad, which can accommodate 100,000m3 of snow.
  • Improved ditching within the site to manage melt water.
  • Phase 1 will utilize existing lagoon No 4 as the melt water pond.
  • The drainage pipe will be installed from the melt water pond to Atim Creek
  •  
Construction of Snow Dump Site - Phase 2, CE1515.1
Phase 2 will include the following:
  • Expanded snow pad to provide 300,000m3 of snow storage.
  • During this phase, the Phase 1 and 2 pad area will be upgraded to include the proposed synthetic liner and roller compacted concrete.
  • The existing lagoon cell will be deepened, and the lift station will be installed.
  • The deepened lagoon will be lined with a synthetic liner to provide environmental containment.

Construction of Snow Dump Site - Phase 2, CE1515.1
Phase 3 will include the following:
  • Expanded snow pad to provide 1,000,000m3 of storage.
Administration proposes that the usage of the new Snow Storage Facility be monitored over the next few years to determine when the Phase 2 upgrades to 300,000m3 of storage will be required and subsequently, when the Phase 3 upgrades to 1,000,000 m3 will be required. It is estimated that after construction of Phase 1 in 2020, Phase 2 will be required within 4 years and Phase 3 would be required in 10 to 12 years.
Options/Alternatives
Council may request changes to this Corporate Plan initiative. Any changes that are requested will require an amendment to the corporate plan, and a budget adjustment. 

Alternative 1:  Make an amendment to the initiative. 
 
That the 2020-2022 Corporate Plan be amended to revise initiative CE428 - Detailed Design and Construction of Snow Dump Site, by:
[indicate changes requested]; and
 
that Administration be directed to bring forward any financial implications that may be required through a spring budget adjustment.


Alternative 2: Request that Administration to look into other options available for the future to ensure that City continues to have the proper capacity for its snow storage needs.

Consultation/Engagement
Throughout the needs, phasing, and design stages of the project, there has been consultation with Parkland County Planning and Development staff and with Alberta Environment and Parks. Geotechnical work, a Limnology Study and a Noise Study have been completed.
Implementation/Communication
Prior to a tender to contractors, the City will work with Parkland County to host an information session for Parkland County residents who live adjacent to the Snow Storage Facility.
Impacts

There are a number of options identified in the RFD.  If the City does not pursue construction of a new snow storage facility, it will eventually have impacts in the operational capacity of PW and may affect service levels during snow events.  


Fiscal Impact
Financial Implications:
When this project was originally initiated, the following items were not anticipated:
  • Access to the Snow Storage Facility and Sewage Lagoons needs to be relocated to accommodate trucks.
  • Construction of a turning lane on Century Road at the access to the Snow Storage facility to accommodate queuing of trucks is required by Parkland County.
  • Noise attenuation berm and landscaping, west of the snow storage pad is required by Parkland County.
  • For construction of Phase 1, the City will need to source approximately 7,000 m3 of clay to construct the snow storage pad and access road.
This increase in scope and cost associated with the Snow Storage Facility project impacts future budgeting as the following amounts will be required to complete the staged implementation of the Snow Storage Facility:
 
2014 – Snow Dump Site Pre-design in on the Corporate Plan. A cost of $50,000 was allocated to do some pre-design work. 
 
2015 – Detailed design and Construction of Snow Dump on the Corporate Plan. $1,100,000 was identified to complete the design and construct the snow facility over three years (one for design two for construction).
 
2016 - Detailed design and Construction of Snow Dump on the Corporate Plan. $1,100,000 was identified to complete the design and construct the snow facility over three years (one for design two for construction).
 
2017 - Detailed design and Construction of Snow Dump on the Corporate Plan. $1,285,000 was identified to complete the design and construct the snow facility over three years (one for design two for construction). Increase due to inflation and other construction costs.
 
2018 - Detailed design and Construction of Snow Dump on the Corporate Plan. $1,285,000 was identified to complete the design and construct the snow facility over three years (one for design two for construction).
 
2019 - Detailed design and Construction of Snow Dump on the Corporate Plan. $1,780,000 was identified to complete the design and construct the snow facility over three years (one for design two for construction). Increase due to additional requirement (see write-up) and inflation cost.
 
2020 – The 2020 Corporate Plan includes $1,565,600 budget to construct Phase 1 of the Snow Storage Facility. This budget includes Construction cost of $1,462,000 and Engineering and Geotechnical Testing.  This project is proposed to be funded by Municipal Sustainability Initiative funds.
 
Future – Phase 2 - $1,637,000 plus Engineering, Testing, and Contingency costs for a total of $2,046,250 (estimated in 2020 dollars and will need to be revised closer to time of construction).
 
Future – Phase 3 - $1,452,000 plus Engineering, Testing, and Contingency costs for a total of $1,815,000 (estimated in 2020 dollars and will need to be revised closer to time of construction).
