Rooftop & Rainwater Gardens

The Riverdale Hub offers an innovative and affordable green work environment to progressive organizations and individuals. At the same time, the Hub provides placement opportunities and training to women through its social enterprises – creating a bridge between minority groups and mainstream communities through shared space, kindred spirit and common vision.

Rooftop Garden Benefits

Rooftop Gardens utilize rooftop space for growing plants. There are several possible advantages. The gardens can be beneficial to the environment, as well as the rooftop and building themselves.

 

Rooftop gardening improves the quality of the atmosphere. The plants absorb carbon dioxide in the air and convert it into oxygen, which is released into the air. Since the rooftop plants can absorb some of the excess amounts of carbon dioxide higher up in the air, they can potentially reduce the effects of air pollution.

 

Another environmental advantage is in the increased energy conservation. The plants provide natural insulation to the rooftop by reflecting light and heat. The extra insulation reduces the need for heating or cooling mechanisms, which cuts down on energy use and utility costs. This also blocks outdoor noises.

 

Many large cities experience increased daytime temperatures caused by numerous rooftops. Since urban areas tend to have more buildings, the rooftops absorb heat and light and then radiate it back into the area. This event is referred to as the “heat island effect” and can actually raise the natural temperature averages in those areas. Plants in rooftop gardens can aid in reducing “the heat island effect” by partially absorbing some of the sunlight and providing shade for buildings.

 

Rooftop gardens may be beneficial in areas which accumulate a great deal of rain. Storm runoff water can especially overflow sewer systems. The plants can absorb some of the rainwater and limit the runoff from excess water. Rooftop gardening, in turn, has the potential to reduce the occurrences of flooding.

 

Using rooftops to grow plants can free up ground space. This extra space can leave room for growing more agricultural crops. Rooftop gardens can also provide more opportunities for growing fresh produce for populations that have little ground area for crops, which can help reduce food shortages in poor, urban areas.

 

Gardening is also very therapeutic. In Canada, horticultural therapy has been used increasingly as an evidence-based practice over the past sixty years. social and therapeutic horticulture projects can help foster independence, build self-esteem and confidence, and provide training and employment opportunities for people with health and social problems.

Stage 1 - Green Roof

The green roof captures rain events, and manages water through several processes. Plants capture and store water for use in dry periods. Water is stored in the growing medium, and wicking action alone releases rain into the air after a rain event. During the growing season, evapo-transpiration by plants releases stored rain into the air.

 

A mix of native and non-native species were planted that have a variety of adaptations. The high diversity of plants forms a community that is adaptable to a variety of weather patterns from moist spring weather to long summer droughts.  

 

The following plants have been planted on the roof:

 

  • Allium cernuum                             

  • Nodding Wild Onion

  • Allium flavum                                      Yellow Chives

  • Allium schoenaprasum

       Wild Chives

  • Liatris cylindracea

       Dwarf Blazing-star

  • Penstemon hirsutus

       Hairy Beardtongue

  • Phlox subulata

       Moss Phlox

  • Schizachyrium scoparium

       Little Bluestem

  • Sedum album

       White Stonecrop

  • Sedum reflexum

       Blue Spruce Stonecrop

  • Sedum spurium

       Red Stonecrop

  • Sedum kamtchaticum

       Russian Stonecrop

  • Sedum sexangulare

       Six-angled Stonecrop

  • Sedum pulchellum

       Annual Stonecrop

  • Sedum ternatum 

       Appalachian Stonecrop

  • Tradescantia ohioensis

       Ohio Spiderwort

 

Once the green roof is fully saturated, excess water is directed by the roof drain to the rain garden below for the next chain of water management.

 

Apart from alternate water options, our green roof provides a multitude of benefits for the building as well as the city including increased air quality, greater biodiversity and energyconservation. For more information on our green roof visit
