The restoration of this degraded, urban stream yields ecological function and value while providing high school students with hands-on environmental science experience and an enriching, living outdoor classroom. Participants will learn from this real-life example how city officials can work with a local school districts to empower students to restore habitat, while ensuring the protection of downstream property and preventing flooding.

Challenges of Multi-Goal Urban Stream Restoration-Kovalcik and Borcherds, 2012
- 1. Great Lakes Restoration Conference September 11, 2012 Challenges in Multi-goal Stream Restoration Projects Peter Briggs
- 2. Great Lakes Restoration Conference September 11, 2012 Presenters Paul Kovalcik Senior Environmental Scientist J. Meiring Borcherds Biohabitats, Inc. Regional Watershed Coordinator Great Lakes Bioregion Office Cuyahoga County Board of Health
- 3. Great Lakes Restoration Conference September 11, 2012 Workshop Goals • Looking beyond habitat and improved ecology • Learn perspectives of from multiple stakeholders • Making the most out of available funding USFWS , Edward Steenstra USFWS ,Steve Hillebrand USFWS , Thomas Barnes
- 4. Great Lakes Restoration Conference September 11, 2012 Hudson High School Tinkers Creek Stream Restoration
- 5. Great Lakes Restoration Conference September 11, 2012 Tinkers Creek Stream Watershed • Largest tributary to the Cuyahoga River (96 square miles) • Approximately 30 miles in length • Drains 24 communities in three different counties • Nearly 19% impervious surface (range 6% to 47% for the subwatersheds) • Tinkers Creek Watershed Partners Project Site
- 6. Great Lakes Restoration Conference September 11, 2012 Hudson High School Tinkers Creek Stream Restoration • 180 acre watershed (0.28 sq mi) • Medium density residential development • 17% impervious surface • Restoration reach was once ditched and straightened • Entirely on High school property
- 7. Great Lakes Restoration Conference September 11, 2012 Existing Conditions
- 8. Great Lakes Restoration Conference September 11, 2012 Project History • In 2000 HHS teachers began developing the concept of using the stream corridor as a land lab to teach advanced ecology and biology. • During summer 2003 the City of Hudson experienced severe/fatal flooding, completed an aggressive Stormwater Master Plan in 2004, and updated stormwater regulations. • In 2005 a Watershed Master Plan was developed for Tinkers Creek • In 2008 the Cuyahoga County Board of Health, in partnership with Tinkers Creek Watershed Partners, City of Hudson, and the Hudson City School District, applied for and received a 319 Grant through the Ohio EPA.
- 9. Great Lakes Restoration Conference September 11, 2012 Stakeholders and Priorities • Ohio EPA - Correct NPS caused water quality impairment to Ohio’s surface water resources work toward aquatic life use attainment in impaired waters (improved aquatic habitat and water quality). • Hudson High School - High quality education through development of an Outdoor Land Lab • City of Hudson - Increased retention/detention • Cuyahoga County Board Of Health - Improved surface water quality to protect public health
- 10. Great Lakes Restoration Conference September 11, 2012 Our Task • Four groups • Develop your goals and objectives for the project • Report to the group
- 11. Great Lakes Restoration Conference September 11, 2012 What Happened USFWS , Dave Menke
- 12. Great Lakes Restoration Conference September 11, 2012 Project Goals • Improved water quality and reduced erosion • QHEI of 60 by June, 2012 • Wetland floodplain and in-stream habitat creation • Develop a high quality land lab with Hudson High School Teachers • Dissipate stream energy • 2.0 million gallons of storage in the channel and floodplain • Attenuate the existing 25 year storm discharge down to the 2 year predevelopment rate
- 13. Great Lakes Restoration Conference September 11, 2012 Design Elements • Hydrology and Hydraulics • Compatibility of retention/detention with habitat restoration • Student access • Excess soil excavation • Design specifications for culverts • Limited budget for planting
- 14. Great Lakes Restoration Conference September 11, 2012 Habitat and Water quality • Floodplain riffle weirs to maximize floodplain wetland habitat • Improved sediment and pollutant processing • Increased pool habitat • Wet meadow, emergent wetland, scrub shrub wetland, and riparian forest planting zones will be installed.
- 15. Great Lakes Restoration Conference September 11, 2012 Habitat and Water Quality
- 16. Great Lakes Restoration Conference September 11, 2012 Habitat and Water Quality
- 17. Great Lakes Restoration Conference September 11, 2012 Habitat and Water Quality
- 18. Great Lakes Restoration Conference September 11, 2012 Land Lab • One stream day of pre-restoration monitoring in spring 2012 • Students will continue to monitor the restored channel. • Designated paths and monitoring stations established • Habitat “classrooms” associated with planting zones • Students will assist with planting in November 2012
- 19. Great Lakes Restoration Conference September 11, 2012 Floodplain Retention and Storage • 2.0 million gallons of storage capacity • Pre-development 2 year discharge achieved • Passage of aquatic life maintained
- 20. Great Lakes Restoration Conference September 11, 2012 Floodplain Retention and Storage
- 21. Great Lakes Restoration Conference September 11, 2012 Floodplain Retention and Storage
- 22. Great Lakes Restoration Conference September 11, 2012 Summary/Lessons Learned • We often do not understand the full implications of our goals until the design process. • Multi-goal projects present challenges, but the rewards are high. • Never stop looking for funding to improve the project.

Editor's Notes
- Tributary to Tinkers Creek
- Tinkers Creek Land Conservancy prepared a watershed Plan in 2005
- Within what is known as the Hudson Springs subwatershed
- In 2000 was simply a drainage ditch corridor used occasionally by some biology teachersMore emphasis placed on science and less on social/global studies.Field studies became a major component as opposed to entirely classroom based learningSustainability and sustainable practices stressed at a local and personal level to improve responsibility and best practices within the communityThe City identified the floodplain around the HHS Tributary as an opportunity to retain stormwater.
- Over 12,000 CY of material excavated and placed on upland areas around the school property.Sound barrier for the highway one practice field raised and leveled
