Phase 4 of the Mid-America Regional Council (MARC) Green Infrastructure study provides an assessment of key measures of resilience in the region. This study establishes a baseline measurement for each metric and how often the calculations should be updated to test progress. It also highlights relevant policy goals. Building on the previous phases green infrastructure analysis, strategy, and regional engagement this study focused on four priority categories: 

1. Flood Risk Reduction

2. Water Quality Improvement

3. Habitat Improvement and Climate Protection

4. Public Health Improvement

Each category is also evaluated through the lens of social vulnerability. The purpose of this study is to provide data to decision-makers that can inform equitable regional investment based on an understanding of the greatest needs and opportunities
to benefit people and nature while becoming a more resilient region.

​

The parameters established to guide the development of Green Infrastructure Metrics hinged on using readily available data maintained by MARC. The ease of updating the measurement calculations over time is a key factor in the value and usefulness of the metrics. The frequency of updates and expectations for a timeframe of change were also factors considered in determining the metrics selected to measure change.
