Lazarro RunLocation: Cuyahoga County, Ohio. View location map Overview of the Problem This small, steep headwater stream became unstable as a result of residential development in the watershed. Storm water routing and added impervious surface increased the frequency and volume of the channel forming flows, resulting in an unstable and unsightly channel. The channel quickly became entrenched and downcut 6 feet, causing massive slope failures, debris dams and flooding.. Restoration Solution The restoration approach involved a Priority 1 restoration, converting stream type from G to B2a and raising the streambed back to pre-development elevations in the valley. The restored stream geometry was stable, functional, and efficient at moving sediment.
