challenges of multi-goal urban stream restoration-kovalcik and borcherds, 2012
DESCRIPTION
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.TRANSCRIPT

• 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

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.

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

• 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.
