Sustainable Sites Looks at the Land Before Drawing the Building
In Part 1, we introduced the Sustainable Sites category within LEED and explored why thoughtful site design matters—not only for the environment, but for healthier, more resilient communities.
This time, I’d like to take a tour through the six Sustainable Sites credits and show how they work together.
One of the biggest opportunities in sustainable design begins before a building is ever constructed.
“The most important decisions in a LEED project are often made before the architect’s pen is ever put to paper. Once those decisions are built into the design, certification simply becomes an option—not the purpose.”
Rather than asking, “Where should we place the building?” LEED first asks:
- What already exists on this site?
- How does water naturally move across the land?
- What habitats should be protected?
- Where does the sun travel?
- How can we work with nature instead of against it?
Those early conversations shape everything that follows.
By understanding the land first, projects often become less expensive to operate, more resilient during extreme weather, and more comfortable for the people who use them.
The Sustainable Sites category is organized into six credits that guide this planning process.
1. Site Assessment
Every successful project begins by understanding the land.
Before construction begins, LEED encourages designers to evaluate:
- soils
- existing vegetation
- drainage patterns
- wildlife habitat
- climate
- sun exposure
- prevailing winds
This information helps the design respond to the site rather than forcing the site to fit the design.
Often, expensive problems can be avoided simply because they were recognized before construction began.
2. Protect or Restore Habitat
Healthy landscapes quietly perform valuable work every day.
Native vegetation filters runoff, stabilizes soil, stores carbon, supports pollinators, and provides habitat for wildlife.
Whenever possible, LEED encourages protecting existing natural areas. Where damage has already occurred, restoring habitat becomes an investment that continues paying benefits for decades.
Nature becomes part of the infrastructure.
3. Open Space
Not every square metre needs to be developed.
Open spaces improve recreation, provide wildlife habitat, allow rainwater to soak naturally into the ground, and contribute to the character of a community.
Sometimes the most valuable part of a development is the part left untouched.
4. Rainwater Management
This credit connects closely with much of the work I’ve shared over the years.
For decades we’ve treated rainwater as something to remove as quickly as possible.
LEED encourages a different perspective.
Can rainfall be slowed?
Can it infiltrate naturally?
Can it be filtered?
Can it be reused?
Rain gardens, bioswales, permeable paving, rainwater harvesting systems, and restored drainage patterns all reduce pressure on municipal infrastructure while helping maintain the natural hydrologic cycle.
Rather than becoming runoff, rainfall remains a valuable community resource.
5. Heat Island Reduction
Anyone who has walked across a large asphalt parking lot on a summer afternoon understands this concept immediately.
Dark pavement and roofing absorb enormous amounts of heat.
Trees, reflective roofing, lighter paving materials, green spaces, and shaded parking all help reduce surface temperatures while lowering cooling costs and creating more comfortable public spaces.
6. Light Pollution Reduction
Outdoor lighting should improve safety—not illuminate the night sky.
Well-designed lighting directs light where it is needed while reducing wasted energy, minimizing impacts on wildlife, and preserving our view of the stars.
Sometimes better lighting simply means using it more thoughtfully.
Sustainable Sites: Looking at the Whole Picture
What strikes me most about the Sustainable Sites category is that none of these credits exist in isolation.
Managing rainwater helps restore habitat.
Healthy vegetation cools neighbourhoods.
Open spaces improve biodiversity while reducing stormwater runoff.
Thoughtful lighting saves energy while protecting wildlife.
Together, these six credits demonstrate a simple but powerful idea:
The land itself becomes part of the solution.
Rather than working against natural systems, we begin designing communities that work with them.
For municipalities, that often means lower maintenance costs, longer-lasting infrastructure, healthier ecosystems, and communities better prepared for changing climate conditions.
To me, that’s simply good planning.
“The most expensive building isn’t the one that costs the most to build. It’s the one that costs the most to own.”
Looking Ahead
Over the next several articles, I’d like to explore each of these credits individually.
Many of the principles are already visible here in Diamond Valley.
Others represent opportunities that could strengthen our community for decades to come.
As with so much of sustainability, the biggest benefits often begin long before construction starts.
They begin by understanding the ground beneath our feet.
“Sustainability is the practice of making tomorrow’s problems smaller instead of larger.”
