Commercial landscaping’s water management programs are meant to tackle a multitude of common problems, including the disbursement of organic sediment, heavy metals, hydrocarbons, excess nutrients and man-made debris. They are all unwanted items that have the potential to be left behind during a variety of storm-related events and cause environmental problems or financial losses. As such, maintenance crews in our region must be ever vigilant of their presence and proactive in keeping levels down to the minimum.
How can commercial landscaping’s water maintenance initiatives prevent buildup and expedite removal of said items? It hinges on the materials in questions. For instance, certain nutrients are best reduced through the use of grass swales and baffle boxes. Other material removal jobs may require sorption and filtration materials or hand-picking. They are just a few methods used by stormwater BMP teams operating in our region.
Baffle boxes are frequently used in stormwater BMP maintenance because of their three-dimensional structure. It allows them to effectively trap a number of things, including nutrients, organic sediments and man-made debris (e.g. pop bottles). Once they’re trapped, hand-picking or baffle box flushing may take care of the materials in question. Grass swales and sorption materials, on the other hand, are typically handled differently.
Understandably, grass swales are meant to be permanent fixtures as are some sorption materials (e.g. sand). As such, they are ideally built into basin design from the get go. If the existing sorption materials and grass swales are not effective or efficient enough, crews may up the ante with design revisions or additions. Furthermore, they may choose to remove the spent, sorption materials and replace it with something better.
Water management selections made by commercial landscaping companies are generally based on the existing aquifer and various control elements. For example, they may note peak rate controls and the amount of pollutants typically found in adjacent properties.
