Soil Properties and Their Impact on Projects
Soil properties play a crucial role in construction projects, and understanding them is essential for a successful outcome.
The density of soil can affect the stability of a building's foundation, with dense soils providing a more stable base than loose ones.
Loose soils, on the other hand, can settle unevenly over time, leading to structural issues down the line.
Soil moisture content also impacts construction, as high levels of moisture can cause soils to become unstable and prone to erosion.
Here's an interesting read: Green Roofing and Construction
A soil's water-holding capacity is influenced by its particle size and distribution, with finer soils retaining more water than coarser ones.
The type of soil used in a project can also affect the building's durability, with soils high in clay content being more prone to shrinkage and cracking over time.
Soil pH levels can impact the growth of vegetation and the health of the surrounding ecosystem, with extreme pH levels potentially harming local plant life.
Tree Planting and Maintenance
To grow large, healthy trees in parking lots, designers should provide adequate soil volumes, select heat and salt-tolerant species, and create curbed miniature islands that receive stormwater runoff.
Landscape islands should be designed with high-quality, well-drained soils or structural soils that can be compacted and utilized under pavement, allowing for deeper rooting and better stormwater infiltration and treatment.
Research has shown that structural soils can be effective in parking lots, with a demonstration project in Ithaca, New York, utilizing porous asphalt and gravel-based structural soils, allowing for a six-inch rain event to be infiltrated.
Selecting the right tree species is crucial for parking lots, with heat and salt-tolerant large canopy trees like London planetree, honeylocust, and hybrid elms being good choices.
These species can tolerate harsh conditions and provide useful shade and cooling air and surface temperatures.
Innovative designs can find room for trees in parking lots, such as one-way aisles with angle in parking stalls and creating planting islands between the rows of stalls.
To ensure the long-term health of trees, landscape ordinances can be enacted to require tree plantings in new developments, including parking lots, with standards and requirements like one tree per certain number of parking spaces or 10% of the parking lot landscaped.
Here are some tree species that can thrive in parking lots:
- London planetree
- Honeylocust
- Hybrid elms
- Zelkova
- Oaks like willow oak and swamp white oak
- River birch

Community and Urban Planning
Requiring trees in parking lots can be done through landscape ordinances that set standards for tree plantings. These ordinances can specify one tree per certain number of parking spaces or require a percentage of the parking lot to be landscaped.
Some ordinances go as far as requiring 50% of a parking lot to be covered with tree canopy within 15 years. This means that designers must create room for trees, not just planting them along the perimeter.
A properly designed downtown parking lot can achieve good canopy cover and provide park-like benefits.
Bicycles
Bicycles are a key component of green parking lots, as they are more environmentally friendly than cars.
In Toronto's guide, bicycle storage locations are mentioned as an essential feature of green parking lots. Bicycles are a sustainable mode of transportation that can significantly reduce carbon emissions.
A green parking lot should contain a bicycle rack to encourage people to use bicycles instead of cars. This can help reduce traffic congestion and promote a healthier environment.
According to Toronto's guide, a green parking lot should prioritize bicycle storage to promote eco-friendly transportation.
Trees in Community Areas
Trees in community areas can greatly enhance the aesthetic and environmental appeal of a neighborhood. By incorporating trees into parking lots and public spaces, communities can create a more attractive and sustainable environment.
Requiring trees in parking lots can be a great way to mitigate climate change and reduce urban heat islands. Some ordinances set standards for tree plantings, such as one tree per certain number of parking spaces, while others require a percentage of the parking lot to be landscaped.
However, simply requiring a percentage of the parking lot to be landscaped does not necessarily mean that trees will be planted. Shrubs and flowers around the perimeter might meet the percentage requirement, but they won't provide the same ecosystem services as trees.
Some newer ordinances are requiring 50% of a parking lot to be covered with tree canopy within 15 years. This approach requires designers to create more room for trees, especially in the interior of the parking lot, and not just plant the perimeter or edges.
A properly designed downtown parking lot can achieve good canopy cover and provide park-like benefits. By incorporating trees into parking lots, communities can create attractive and sustainable spaces that mitigate climate change and reduce urban heat islands.
To ensure the success of trees in parking lots, landscape islands should be designed with high-quality, well-drained soils that can be compacted and utilized under pavement. This allows for deeper rooting and better stormwater infiltration and treatment.
