Welcome to the City of Ottawa Carp Road Snow Disposal Facility
Municipal Class Environmental Assessment Public Open House 2
Consultation is a key component of the environmental assessment (EA) process.
The purpose of consultation is to raise awareness and to solicit input fulfilled in part through Public Open Houses. Throughout Phase I and II of the EA, there will be opportunities for the public to comment at key milestones of the project. This is the second of two Public Open Houses planned for this EA.
This Public Open House presents:
- Description of the environment
- Design alternatives considered
- Preferred solution
As you read through the presentation boards and view the presentation, we invite you to share your feedback on the description of the environment, design alternatives and recommendation of a preferred solution.
The City of Ottawa receives an average of 235.7 cm of snow annually and is responsible for road maintenance including snow clearing, haulage and its disposal at selected sites. In 2010, the City estimated it required 3.854 million cubic metres of capacity throughout the City to service its urban snow disposal needs; also, the City identified a deficiency of approximately 0.5 million in disposal capacity, of which 0.2 million was for servicing the West end.
The City’s (2009) Evaluation of Properties for a West District Snow Disposal Facility identified the disposal capacity needed to service the West End to be approximately 357,000 cubic metres. The City reviewed ten potential locations and selected the property at 2125 Carp Road as having potential for development as a SDF.
Closure of several snow disposal locations in Ottawa’s West End (Whalen Park, Glen Cairn, Maple Grove A, Greenbank), with anticipated closure of existing sites at Carp and Maple Grove B have highlighted a need to provide replacement snow disposal capacity in the West End.
During 2012/2013, investigative studies were completed and the following recommendations are made for site development:
- Lower upstream invert of the existing culvert at the Highway 417 outlet to invert elevation 126.19m to improve on site drainage;
- Increase capacity of culverts crossing Westbrook Road to accommodate the 100-yr water level;
- Construct a stormwater pond on site with a footprint of approximately 4ha;
- Construct a SDF with a 357,000m3 snow pack capacity and provide a GCL or geomembrane liner beneath dump pad and snow stockpile area to protect groundwater quality and surrounding wells. Snow stockpile to maintain a 100m setback from residence to the east and include a 4m high berm along the east side for noise attenuation. Snow stockpile height not to exceed 15m. Provide lighting along access road and dump pad;
- Construct a snow meltwater pond (with bottom and sides lined with a GCL or geomembrane) for quality control including an oil/grease interceptor;
- Add a right hand turn lane on Westbrook Road – 90m stacking + 60m taper
- Off-site improvements to roadside ditches and culverts.
- Monitoring program for surface water quality during the melt period.

Site Design Considerations
The following are some key issues that need to be considered in the design of the Site:
- Groundwater protection – the snow disposal pad will be underlain by a low permeability liner to prevent salts and other contaminants from entering the groundwater system.
- Surface Water protection – meltwater runoff from the snow pile will be directed to a lined pond to remove sediment (including metals), oils and other contaminants from the effluent stream.
- Stormwater – features for the treatment of runoff
- Drainage - due to existing drainage problems off-site, namely a linear retention pond at an adjacent property and roadside drainage, site development will be addressing these issues.
- Landscaping – visual screening of the Site, through tree cover and berms, will be a priority
- Other features of the site development will include site entrance design to accommodate truck traffic, access road, mitigative measures for noise, security, lighting, fencing.
