Urban Growth & Sustainability:Implementation challenges & opportunities

The Story in Guelph

Overview of presentation

1. Growth in the Greater Golden Horseshoe

2. Key policy directions

3. Challenges to going further

Growth in the Greater Golden Horseshoe

Growing mid-sized city 100 km west of Toronto

124,000 today; 175,000 in 2031

Sustainability is a key principle of our local growth strategy

• Fastest growing urban area in Canada

• Third fastest growing urban area in North America

• Grow by over 4 million people by 2031

• 1.7 million new households

• 45% longer commuting times

• 42% increase in auto emissions

• More than 1,000 square kilometres of farmland consumed

By 2031 in Guelph

• 54,000 new residents • 31,000 new jobs

Key policy direction

40% of new growth in the built boundary i.e. not green field

Substantial change in the form of growth

From the fringes to the urban growth centre, nodes & corridors

Goals of “Places to Grow” are addressing many global challenges

• Revitalize downtowns • Create complete communities • Provide housing options• Curb sprawl• Protect farmland & green spaces• Reduce traffic gridlock – greater range of

transportation options

Policy Directions in Water, Wastewater, Waste,

Energy, & Biodiversity

• Water Management Master Plan approved

Key policy direction:

Sustainable use of local resources

i.e. no pipeline to Lake Erie

Protection of local resources

• Water Conservation & Efficiency Strategy (being updated)

• Toilet rebate• Clothes washer rebate • Industrial, commercial and institutional

buy backs• Landscape assessment program • Outdoor water use by-law

• Water conservation co-benefits study – energy and GHG co-benefits

• Industrial Benchmarking Exercise – UG/Province– Guelph is a participating municipality

First LEED Platinum Home in Canada Reid’s Heritage Homes

Rainwater harvesting system

Rainwater collected, filtered and stored in a cistern

Supply 3 toilets, washing machine, dishwasher and outdoor irrigation

50% of water consumption in a typical home

• Wastewater Management Master Plan underway

Key policy direction:

Sustainable use of local resources i.e. the river

i.e. no pipeline

Re-use (re-branding)

• Effluent reuse

• Use of biosolids

• Heat recovery

Capital savings in Wastewater

Global challenge – water quality vs cost ($)

• Reduced need for another anaerobic digester – $5 million

• Elimination of the need for a UV system – $ 8 million

• Deferral of Stage 2 expansion for 10 years– $20 million

• Lystek technology• High quality product

• Land application (fertilizer)

• $1.2 million in avoided annual landfill costs

• Reduced carbon footprint

• Increased green power production

• Energy conservation

Advanced Biosolids Treatment

• Waste Management Master Plan approved

Key policy direction: Zero Waste Philosophy

• Waste minimization (corporate leadership)• Waste diversion from landfill

– recycling, reuse, organics – 55% by 2011 65% by 2016 70% by 2021

• Community Energy Plan approved

Key policy direction:Energy use per capita & resulting GHG emissions will be less than the current global average

Increase in population of 54,000

Net reduction in energy consumption (50% less)

Reduction in GHG from 16 to 7.0 tonnes (60% less)

Setting priority to the CEP recommendations

1. Energy efficiency If you don’t need it, don’t use it

2. Heat Recovery If it’s already there, use it

3. Renewable energy If it makes sense, go carbon free

4. Regional & local Invest where it makes utilities sense to avoid duplication
