AES professionals have been studying, designing and restoring stream and shoreline systems for 30 years. Working with Dr. Luna Leopold, AES Senior Ecologist Steve Apfelbaum documented in the 1970s that, prior to European settlement, most small Midwestern streams lacked defined beds and banks but were, in fact, marshy wet swales with relatively little flow from surface runoff.
Fast forward 200 years, and today we see creeks and streams in every urban center of the country in significant need of repair and restoration. With decreased base flows to sustain aquatic life and increases in peak flows that erode banks and down-cut beds, most urban stream systems are degraded and dysfunctional.
Common to degraded streams are various water quality impairments, invasive species along the banks, and excessive flooding. Ponds and lakes are not immune to these factors – with fluctuations in water levels and an increase in algae blooms.
Erosion and stabilization problems along rivers, streams, lakes and ponds are as varied and dynamic as their structural and ecological systems. Their repair requires a unique combination of ecological and engineering skills.
Our staff of design and planning professionals, experienced scientists and project managers is adept at tackling difficult and unique streambank and shoreline problems on a variety of scales. AES has been the principal consultant in many complex projects, some of which have drawn national and international acclaim.

AES’ ecological design approach follows a process of initial inventory of natural and built features, a scientific assessment of current conditions and land-uses, an informed understanding of historical conditions, and a strong engineering foundation for design and permitting.
Science and engineering is supported and enhanced by an artful landscape design approach that delivers the aesthetic desired and the sustainable, ecological benefits that are practical to achieve.
AES has found that our Ecological Systems Approach provides sustainable performance with multiple long-term benefits and surprising cost-effectiveness. We emphasize sustainable design and construction strategies favoring ecological solutions that not only provide flood abatement and infrastructure protection, but also promote diversity and improve wildlife habitat.
