8,500 sf. Greenroof & Hydroponic Towers Project Week Food Roof Farm St Louis Project Week Food Roof Farm St Louis Project of the Week: March 19, 2018

The availability of fresh, local produce is so important in our cities, and not often found farm-to-table.  But urban agriculture on greenroofs makes rooftop farm-to-table easily accessible!  With AgLanta next week on our minds, we’re once again showcasing the success of the FOOD ROOF Farm in St. Louis by Urban Harvest STL.

We were thrilled to have also featured this wonderful project in our 2017 Greenroofs & Walls of the World™ Virtual Summit with the video “FOOD ROOF Farm: Grow Food, Grow Community” from the founder and farm manager, Mary E. Ostafi.  As the Executive Director of Urban Harvest STL, Mary spoke on how they are fostering food system change in their community. Project Week Food Roof Farm St Louis

Mini Description & Details

Urban Harvest STL, a St. Louis nonprofit, empowers communities to cultivate equitable access to healthy, sustainably grown food and enhance biodiversity in cities.  After years of gardening on the ground, the Urban Harvest STL founders combined their background in architecture with HOK with their experience in urban agriculture to design and build St Louis’s first rooftop farm, the FOOD ROOF Farm.

Community engagement drove the design and the project illustrates various rooftop farming growing techniques including the intensive greenroof, hydroponic towers, raised beds, modular planters and greenhouse and tracks best practices for growing each crop efficiently.

Built in 2015, the 8,500 square foot FOOD ROOF Farm is located in the heart of downtown St Louis above a two-story storage facility utilizing a Sika Sarnafil PVC waterproofing membrane, which doubles as a root barrier; capillary, protective & filter fleece and drainage boards from Optigrün international AG / Optigreen; and pavers from Bison Innovative Products.  With additional consulting and design services from Hanging Gardens, the hybrid intensive greenroof system and farm was built in conjunction with volunteers along with Urban Harvest STL.

Over 250 varieties of vegetables, fruits, herbs and flowers are grown annually and more than 4,000 pounds of organic food was produced in 2017.  The majority is donated to people who need it the most in the community.

Other notable farm features include a Milkweed for Monarchs pollinator garden and keeping over 40,000 honeybees and 5 chickens. Project Week Food Roof Farm St Louis


The community hub space hosts over 20 educational workshops and activities each year.  And, the robust green roof infrastructure captures up to 17,000 gallons of stormwater per storm event, which equates to over 1,819,000 gallons annually.  Rainwater captured is utilized for plant growth, reducing irrigation needs by up to 50%.

Urban Harvest STL set out to not only create a social impact but also create an ecological return as well; they are increasing biodiversity gains and pollinator health on their rooftop.  The FOOD ROOF Farm is growing healthy food and a community of healthy people.
