# **Landscape Integration in Residential Development**
Good residential development treats the landscape as a design element, not an afterthought. Integrating natural features, grading, drainage, and planting into the site plan creates lasting value.

## Building With the Land
Residential development that works with the existing landscape rather than bulldozing it flat produces better outcomes: more attractive streetscapes, lower grading and servicing costs, better drainage performance, greater biodiversity, and higher property values. Landscape integration starts at the initial site planning stage, not after the houses are built.
## Site Analysis
Before any design work begins, a thorough site analysis identifies the natural features and constraints that should guide the development plan:
- **Topography:** Existing grades, slope directions, and elevation changes. Buildings and roads can follow natural contours rather than requiring extensive cut-and-fill operations. Preserving natural drainage patterns reduces the need for engineered stormwater systems.
- **Vegetation:** Existing trees and woodland areas, particularly mature specimens and native species. Preserving existing mature trees provides immediate shade, wind protection, and character that new plantings require decades to achieve.
- **Water features:** Streams, wetlands, ponds, and seasonal watercourses. These features are regulated under Ontario's Conservation Authorities Act and often must be protected with buffer setbacks. Rather than viewing them as constraints, good site planning treats them as amenities.
- **Soils:** Soil types, drainage characteristics, and depth to bedrock or water table. Soil conditions affect foundation design, drainage, septic system feasibility (in rural areas), and plant selection.
- **Microclimate:** Sun orientation, prevailing wind direction, and exposure. South-facing slopes are warmer and drier; north-facing slopes are cooler and moister. Wind exposure affects building energy performance and plant survival.
## Grading Strategy
Grading is the reshaping of the ground surface to achieve desired elevations for buildings, roads, and drainage. Thoughtful grading minimizes earthwork, preserves natural features, and creates a development that fits the land:
- Balance cut and fill volumes on site to avoid importing or exporting large volumes of soil (which is expensive and generates truck traffic)
- Maintain a 2 percent minimum grade away from all building foundations for the first 2 metres (Ontario Building Code requirement) to direct surface water away from buildings
- Preserve existing drainage paths wherever possible and integrate them into the stormwater management system
- Use swales (shallow, vegetated channels) rather than rigid storm sewer pipes in areas where grades and lot sizes allow. Swales filter runoff, reduce peak flow, and are less expensive to construct and maintain.
## Stormwater Management
Modern residential development in Ontario requires a stormwater management plan that controls the quantity and quality of runoff from the development site:
- **Low Impact Development (LID):** LID techniques manage stormwater at or near the source rather than conveying it to a central pond. LID measures include permeable paving, bioretention cells (rain gardens), infiltration trenches, and green roofs. LID is increasingly required or encouraged by Ontario municipalities.
- **Stormwater ponds:** For larger developments, engineered stormwater management ponds attenuate peak flows and provide water quality treatment (settling of sediments and pollutants). Ponds can be designed as naturalized landscape features that add aesthetic and ecological value.
- **Roof drainage:** Directing roof drainage to rain gardens, dry wells, or permeable areas rather than directly to the storm sewer reduces peak flows and improves groundwater recharge.
## Planting Design
Landscape planting in residential development serves functional and aesthetic purposes:
- **Street trees:** Street trees are essential for neighbourhood character, shade, and property value. Select species that are tolerant of urban conditions, salt, and compacted soil. Ontario natives like Red Oak, Sugar Maple, Hackberry, and White Spruce are good choices.
- **Foundation planting:** Shrubs and perennials at building foundations soften the building edge, provide visual interest, and improve privacy.
- **Buffer planting:** Dense plantings along property boundaries, around stormwater ponds, and adjacent to watercourses provide screening, noise attenuation, wildlife habitat, and erosion control.
- **Native species priority:** Native plants require less water, fertilizer, and maintenance than ornamental non-native species. They provide food and habitat for native pollinators and wildlife.
At AVANORTH, we integrate landscape planning into the earliest stages of residential development. Our projects work with the land to create developments that are more attractive, more resilient, and more valuable because the landscape was considered from the start.
