Water quality basins are far from new in the St Louis Metro area.  In some cases, the basins appear almost as an afterthought, tucked back into the rear of a site.  On occasions though, they are placed into a very prominent location on site.  When that happens, they can become showcases of color, texture and function.  They can be treated as assets, horticultural gems, gardens to enjoy and attract pollinators. And thus is the case at AHEAPA III & IV.
