Doing its work
Before the construction of the engineered bioswale, this part of 14th Avenue would wash out and large amounts of gravel would accumulate at the bottom of the hill, at the intersection with 10th St. S. Everytime it rained heavily, public works could be seen cleaning up gravel and other debris at the bottom of the hill. There is more to this swale than is visible but it is certainly doing its job and as the natural vegetation grows in, even more water will be absorbed and have time to penetrate the subsoil preventing it from entering our overburdened storm drains.

Apart from the benefits you mention, it also reduces the amount of silt and gravel being washed in the local creek, which should improve the health of Joseph Creek.
