Nature-Based Solutions for Urban Stormwater Management
Green infrastructure represents the future of sustainable urban development, combining effective stormwater management with environmental restoration and community benefits. Our Low Impact Development (LID) solutions work with natural processes to manage water while creating beautiful, functional landscapes that support biodiversity and enhance property values.
Rain Gardens & Bioretention Cells
Engineered landscape depressions designed to capture, treat, and infiltrate urban runoff. Our rain garden systems remove 80-95% of sediments and 40-80% of nutrients while reducing runoff volumes by 50-90%. Each installation is custom-designed for Toronto's soil conditions and seasonal weather patterns.
Rain Garden Specifications:
- • Size: Typically 20-30% of drainage area
- • Depth: 6-18 inches depression with 18-48 inches engineered soil
- • Infiltration rate: 0.5-8 inches/hour based on soil conditions
- • Plant zones: Wet, middle, and dry areas with appropriate species
- • Overflow systems for extreme rainfall events
- • Pretreatment areas for sediment capture
- • Underdrain systems where natural infiltration is limited
Bioswales & Vegetated Channels
Linear green infrastructure systems providing stormwater conveyance, treatment, and infiltration. Our bioswales combine the functionality of traditional drainage with the environmental benefits of native plant communities, creating attractive landscape features that improve water quality.
Bioswale Design Elements:
- • Longitudinal slope: 1-5% for optimal flow velocity
- • Side slopes: 3:1 or flatter for stability and maintenance
- • Check dams: Stone or wood structures for flow control
- • Native plant communities adapted to flow variations
- • Engineered soil media for enhanced infiltration
- • Energy dissipation structures at inlets
- • Maintenance access paths for long-term care
Green Roofs & Living Wall Systems
Building-integrated green infrastructure providing stormwater management, energy benefits, and habitat creation. Our systems include extensive green roofs (lightweight, low-maintenance) and intensive green roofs (garden-like with diverse plantings). Living walls provide vertical stormwater management opportunities.
Green Roof Systems:
- • Extensive systems: 4-6 inches growing medium, sedum and grasses
- • Intensive systems: 6-24+ inches medium, diverse plant palette
- • Stormwater retention: 50-90% annual runoff reduction
- • Structural loading: 15-150 lbs/sq ft saturated weight
- • Drainage layers with overflow drains and scuppers
- • Insulation benefits: R-2 to R-10 additional insulation value
- • Lifespan: 40-60 years with proper maintenance
Constructed Wetlands & Treatment Systems
Engineered ecosystems that mimic natural wetland processes for advanced stormwater treatment. These systems provide exceptional pollutant removal while creating valuable habitat and educational opportunities. Ideal for larger properties and institutional applications.
Wetland Treatment Components:
- • Pretreatment cells for sediment removal
- • Shallow marsh zones with emergent vegetation
- • Deep water zones for extended detention
- • Micropool areas for permanent water storage
- • Native wetland plants: cattails, bulrushes, water lilies
- • Wildlife habitat features: nesting boxes, basking areas
- • Maintenance access for long-term management
Tree Box Filters & Urban Forest Stormwater Management
Silva Cell & Structural Soil Systems
- Underground tree root systems with integrated stormwater management
- Suspended pavement systems allowing root growth under walkways
- Structural soil mixes supporting both trees and pavement loads
- Integrated drainage and irrigation systems
Stormwater Benefits
- Canopy interception: 20-30% rainfall captured by tree canopy
- Root zone filtration: Enhanced infiltration and treatment
- Evapotranspiration: Additional moisture removal from soil
- Urban heat island reduction: Cooling effects reduce runoff temperatures

FAQ
Green Infrastructure Frequently Asked Questions
Expert guidance on sustainable stormwater solutions and Low Impact Development
How much does green infrastructure cost in Toronto?
Green infrastructure costs vary by system type: Rain gardens: $17-45/sq ft installed including plants and engineered soil, Bioswales: $27-55/sq ft for complete installation with native plantings, Green roofs: $20-50/sq ft depending on extensive vs intensive systems, Constructed wetlands: $37-85/sq ft for treatment area including liner and plants. Complete residential LID systems range $13,000-75,000, while commercial projects range $27,000-200,000+ depending on size and complexity. Most projects qualify for municipal rebates and development charge reductions.
How long does green infrastructure installation take?
Installation timelines depend on system complexity: Rain gardens: 1-2 weeks including excavation, soil preparation, planting, and establishment, Bioswales: 2-3 weeks for linear systems with grading and plantings, Green roofs: 3-6 weeks including structural assessment, membrane installation, and planting, Constructed wetlands: 4-8 weeks for complete ecosystem establishment. Planning and design phase takes 2-6 weeks. Best installation timing is spring (April-May) or fall (September-October) for optimal plant establishment. Winter installations possible with special establishment protocols.
What are the main benefits of green infrastructure for Toronto properties?
Green infrastructure provides multiple benefits: Stormwater management: 50-90% runoff reduction, foundation protection through improved drainage, Property value: 8-15% increase from sustainable landscaping and environmental features, Energy savings: Green roofs provide additional insulation reducing heating/cooling costs by 10-30%, Environmental: Carbon sequestration, air quality improvement, urban heat island reduction, Regulatory compliance: Meets Toronto Green Standard requirements for development approvals, Financial incentives: Development charge reductions, stormwater fee credits, potential insurance benefits, Biodiversity: Native habitat creation supporting pollinators and urban wildlife.
When should I consider green infrastructure for my property?
Green infrastructure is beneficial in several situations: New construction: Integrate LID systems during initial development to meet TGS requirements and maximize benefits, Drainage problems: Persistent water pooling, foundation moisture issues, or inadequate stormwater management, Property renovation: Major landscaping projects, addition construction, or site improvements, Regulatory requirements: Development applications requiring stormwater management or environmental performance targets, Sustainability goals: LEED certification pursuit, corporate environmental commitments, or personal environmental values. Properties with slopes, large roof areas, or paved surfaces see greatest benefits. Spring planning allows summer installation for fall establishment.
