1 Green Bulkheads in the Cuyahoga River Christopher Streb, PE And Elaine Price Cuyahoga Planning Commission July 29, 2014

2 River that oozes rather than flows TIME

3 Cuyahoga River 100 miles long Headwaters in Geauga County Area of Concern: 1985 IJC, others identify 43 Great Lakes Basin AOC s 1988 Cuyahoga RAP establish AOC as lower 45 mi. Ohio Edison Dam to Lake approx. 10 mi. shoreline (Edgewater to Wildwood) Beneficial Use Impairment including: Restrictions on fish and wildlife consumption Degradation of fish and wildlife populations Fish tumors or other deformities Loss of fish and wildlife habitat Project Area Ship Channel Slightly Above Head of Navigation

4 GREEN BULKHEAD PROJECT Second Iteration High Performance Shoreline Project 2007 CPC partnership with U.S. Army Corp of Engineers 2008 Preliminary prototype Cuyahoga Hanging Underwater Basket (CHUB) Second Iteration 2009 Monitoring plan Market-available habitat types 2010 Developed rigging system Samsel Supply Installed in ship channel Samsel Supply; Trident Marine

5 Purpose & Goals Purpose: Goals: Discover/ Design Habitat Interventions Test in Cuyahoga River Transferable to ship channels around the world 1. Re-establish a Viable Fish Population/Cycles 2. Maintain Active Shipping Industry fish

6 Fish Cycle

7 Larval Fish Needs Design Criteria Food: phyto-; zooplankton Shelter: camouflage, shadows Rivers Edge Surface to 24 Depth Short Swim from Spawning March June Matrix (Roots) Matrix (Vegetation) Edge Placement Buoyant Placement near Head of Nav. Last Year s Vegetation

8 Floating Islands

9 Beemats

28 Functions 1. Dissipate energy 2. Transport larval fish 3. Nourish 4. Provide habitat 5. Increase DO 6. Cool water 7. Clean water 8. Quiet Noise 3. Nourish 4. Provide habitat 5. Increase DO

29 Discovering

30 What Natural Models do we use? Forms/Structures Processes Materials Relationships Patterns Systems Principles

31 DISCOVERING Discover Natural Models Function: How does nature create shelter?

32 DISCOVERING Discover Natural Models Function: How does nature trap or transform biomass?

33 DISCOVERING Discover Natural Models Function: How does nature oxygenate?

34 Creating

35 CREATING Brainstorm Bioinspired Ideas

36 CREATING Emulating design principles

37 CREATING Leveraging cyclical processes Capture carbon Fish recruitment and siting habitats Use wave energy from boats Photo courtesy of Jim White

38 CREATING Design criteria Modular Heavy sediment loads Ice flows Limited maintenance Durable

39 CREATING Emulating form

40 CREATING Green bulkhead casing

41 CREATING Green bulkhead inserts

42 Next Steps: Procurement Fabrication Installation Monitoring
