Why we want McMaster to act on their campus plan MINIMUM 30metre buffer between parking lots and Ancaster Creek (AKA Coldspring Creek):
"Riparian buffers function as water filters. When it rains, buffers trap pollutants and eroded soil before they get into the creek. While keeping the creek water clean, buffers provide food, shelter and shade for fish, frogs, birds and small animals. They also stabilize creek banks, which helps prevent soil erosion.
Environment Canada's Habitat Guidelines recommend a 30-metre buffer along cold water creeks and a 15 - metre buffer along warm water creeks for these ecological features to perform their function. There are many creeks in our watersheds that do not meet these standards.
The 1999 map of [Hamilton Conservation Authority] HCA riparian buffer data shows that the area's urban creeks have insufficient riparian buffers when compared to these environmental standards. The upper subwatersheds of Spencer Creek and Red Hill Creek show an average amount of vegetation, but still do not have adequate riparian cover along these watercourses. The headwaters of Spencer Creek and the creeks within the Dundas Valley show sufficient riparian buffers. HCA is continually working to preserve these important ecological features.
It is HCA's goal that every creek, where possible, will meet the standards for riparian buffers as defined by its governing environmental organizations.
HCA is committed to continuing efforts to work with private landowners to establish as wide a buffer as their property permits."Despite comments from the University suggesting there exist 30m buffers, the major parking lot "M" has no active lots that are even close to 30m.
