Program Overview

Twenty years ago, the Big Darby Accord marked a groundbreaking commitment to protect one of Ohio’s most ecologically significant waterways while guiding responsible regional growth. The Big Darby Creek, a Scenic River that is home to extraordinary fish and mussel diversity despite covering just one percent of the state’s land area, has long been a symbol of how cross-sector collaboration can conserve valuable natural resources. Today, two decades after the original Accord, development pressures are rising and there is a new cohort of professionals who are involving in planning and managing the Big Darby Creek watershed. Therefore, it's a critical time for a retrospective. At this program, we will revisit the original inspiration for the Big Darby Accord and the hard-earned lessons for management and planning that have been accumulated along the way.

This Environmental Professionals Network program is not about shaping policy. It is about reconnecting with the stories, values, and vision that shaped the original 2006 Accord. The panel will share firsthand experiences from those who helped craft the original agreement, revealing how scientists, planners, homebuilders, and conservationists worked together to balance myriad interests and values. We will revisit pivotal moments—from early biodiversity discoveries to the tensions surrounding a failed proposal to make the Big Darby a National Wildlife Refuge—and explore why collaboration remains essential today.

What We Heard: Community Perspectives from the Big Darby Networking Session

Question 1: What is your vision for Big Darby Creek (or your home watershed) in 2050?

Ecological Health and Biodiversity

Biodiversity of today is maintained or improved.
Mature, protected riparian corridors with clean water and healthy habitat.
Land around the creek is preserved or restored to support wildlife and ecosystem function.
Climate‑resilient landscapes (forested/shaded areas, groundwater recharge zones).

Community Engagement and Collaboration

A community that deeply values the watershed and understands how natural resources are interconnected.
Strong environmental ethic passed to the next generation; children and adults alike actively involved.
Increased outdoor recreation (creeking, trails, nature experiences) that builds public appreciation.
Broad public outreach to help people understand what has gone wrong and how they can help.

Smart Planning and Responsible Development

Development follows a well‑defined plan emphasizing redevelopment/infill over expansion.
A “plan with teeth” (i.e., that has clear rules, accountability, and enforceability).
Incentives for landowners to preserve ecological values.
Big Darby recognized nationally as a model for multi‑stakeholder watershed planning.
Jurisdictions cooperate to determine a sustainable development footprint and commit to staying below it.

Economic Recognition of Natural Value

Ecosystem services and economic benefits of the watershed clearly communicated to decision‑makers.
Recreation, natural beauty, and preserved landscapes support a thriving local economy.

Question 2: What are barriers to Protecting Watershed Integrity While Meeting Human Progress Needs?

Governance, Enforcement and Coordination Challenges

Insufficient administrative power to enforce regulations or share expertise across jurisdictions.
Lack of “teeth” in current plans means there are few consequences for noncompliance.
Difficulty breaking from traditional development norms and systems.

Knowledge Gaps & Ecological Understanding

Incomplete understanding of biophysical thresholds and drivers of ecological decline.
Missing early‑warning indicators (“no canary in the coal mine”).

Economic & Development Pressure

Rising property values, population growth, and market demand for new housing.
Strong political pressure to create affordable housing, even when new builds are not always affordable.
Desire for personal space/homeownership driving expansion over infill.

Cultural and Social Barriers

Lack of awareness or appreciation of the watershed’s value, especially without charismatic species to generate interest.
Low adoption of pro‑environmental behaviors on private land due to limited personal connection or incentives.
Short‑term thinking that prioritizes immediate economic gain over long‑term ecosystem health.

Infrastructure & Transportation Constraints

Transportation patterns that reinforce sprawl.
Need for updated infrastructure strategies and innovative development models.

Question 3: What are Indicators of Success/Failure of the Accord? And what are Strategies to Balance Conservation and Development?

Indicators of Success

The existence and active use of a comprehensive watershed plan.
Maintaining or improving biodiversity, species richness, and water quality.
Expanded participation in the Accord by additional municipalities (highly important).
Consistent adherence to pre‑planned limits (e.g., sanitary sewer boundaries).
Guaranteed, stable funding and incentives supporting ongoing protection work.
Collaborative relationships with developers who plan responsibly within the watershed.

Indicators of Failure

Slippage from agreed‑upon development provisions.
Piecemeal or inconsistent implementation of open‑space requirements.
Continued loss of ecological health despite planning efforts.

Strategies for Balancing Development and Conservation

Identify ecological thresholds and commit to staying within them (use Integrated Prioritization System data to guide management).
Municipalities adopt aligned zoning, incentives, and development standards.
Strengthen mitigation frameworks to include land use, forest cover, and impervious surface reduction.
Improve cultural norms around water protection across the watershed.
Create a large, coordinated master plan involving more stakeholders and financial mechanisms.
Prioritize redevelopment and infill instead of expansion/annexation.
Clearly define open space requirements and develop a prioritization plan for protection types.
