Cavanagh Construction proposes a huge sand and gravel pit directly on the borders of Barbers Lake

  • A Class “A” pit operation with excavation below the water table operating 12 hours a day - 7 days a week (7 am to 7 pm)

  • Only a 30 metre setback from the sensitive wetland shores of Barbers Lake

  • Crushing, washing, and screening plants with recycling of imported construction waste and asphalt

  • Licence to remove up to 500,000 metric tonnes of aggregate annually

  • A truck every 2 minutes on the Highland Line, and continuing through Lanark Village to points east and south

  • The technical reports Cavanagh has submitted leave many unanswered questions about: traffic and roads; acoustics; the dark night sky; the impact on springs, aquifers, and wells; the impact on wetlands; loss of habitat and threat to species at risk; pre-contact archaeology; air quality;human health; property values; resource allocation; potential release of on-site uranium; climate change

  • In short, this proposal is an assault on the environment and the community surrounding McDonald’s Corners

Impacts

Removal and export of the entire hill forming the western shore of Barbers Lake

  • Potential destruction of important pre-contact artifacts

  • Loss of wildlife habitat in the vicinity of Barbers Lake and Long Sault Creek

  • Impact on property values and quality of life for waterfront and haul route communities

  • Damage to existing and future eco-tourism

  • Harm to water bodies through warmed water, potential contamination and silt

  • Threat to residents’ water supply, air quality, peace and well-being

  • Potential future demands, including a water taking licence, or permission to dewater

Aggregate is necessary for the growth and development of roads, housing and business!

Ontario has 13 times more aggregate than currently needed in already licensed pits

Misconceptions

This is revenue for the Township!

Lanark Highlands Township gets only 13 cents per tonne of aggregate taken away from the Township forever - in this pit the maximum payout possible would be $73,500 (14.7 cents x 500,000 = $73,500 per year), but likely much less - and MUCH MUCH less than the costs of road upgrades, loss of nature-based business and tourism, and the diminished value of properties throughout the area.

The other sites in yellow are existing gravel pits. At present, none of these local pits operate below the water table.
