Proof Of Concept

Background

Hancock County and the City of Findlay began working with the U.S. Army Corps of Engineers in 2007 to develop a flood risk reduction plan that could be eligible for Federal funding. The Corps’ final recommended plan, the Western Diversion of Eagle Creek, was presented in 2015 but was deemed unlikely to meet Federal funding requirements. In the summer of 2016, the Hancock County Commissioners engaged the services of the Ohio offices of Stantec Consulting Services Inc. to review the Corps’ plan, look for ways to improve it and ultimately recommend a flood-risk reduction program that more appropriately met the needs of the community. Stantec’s initial concept was introduced in February 2017, and the draft Proof of Concept Report was completed in July 2018.

Stantec’s Recommended Concept

Stantec’s charge was to cost-effectively reduce the risk of flooding and its impacts on roadway access, residential and farmland properties, and job creation and retention. Stantec focused its study on a 100-year-flood (that is, a flood that has a 1% chance of occurring in any given year; also sometimes referenced as 1% ACE). After reviewing the Corps’ plan and exploring alternatives, Stantec proposed a three-part program comprising a suite of independent projects:

  1. Hydraulic improvements to the Blanchard River within the City of Findlay, including removing low-head dams and widening the floodplain bench.
  2. A dry storage basin on Eagle Creek adjacent to U.S. 68 in lieu of the diversion channel that was proposed by the U.S. Army Corps of Engineers.
  3. Dry storage basins on the Blanchard River and Potato Run.

Current Status

The Maumee Watershed Conservancy District (MWCD) assumed administration of the flood risk reduction program through a Memorandum of Agreement with Hancock County in 2016. The MWCD has authorized moving forward with the Hydraulic Improvements component of the program (Project 1).
