The consulting company hired by the City of Niagara Falls to take on their Cannabis Growing Facilities Land Use Study came back with one strong recommendation.SGL Planning & Design said the City would be best served with licenced marijuana growers using indoor growing facilities, rather than outdoor.SGL examined a number of factors in making their determination, such as odour, separation distances, site plan control, crime and enforcement; property values; traffic impacts; social and tourism impacts; environmental impacts and building/fire code compliance.Their report noted, “The most prevalent concern heard from residents was the issue of odour release during cannabis cultivation and processing and the possible impact odour will have on their loved ones and the enjoyment of their properties.”The Canadian Cannabis Act Regulations require air filtration and ventilation systems for indoor cultivation and processing facilities.
