Design Concepts Principals Contribute to NCSU’s Cost Analysis for Improving Park Facilities Study

The wide availability of public parks in communities across the country makes them important resources in promoting active lifestyles. A number of studies suggest that parks contribute significantly to physical activity (PA) among adults and children but not all park features produce the same levels of physical activity. Some studies suggests that parks are used more often and users are more active following improvements or renovations, but the cost may vary greatly among different types of improvements and features. To find the optimum balance between cost and PA participation a number of questions should be considered, such as: What are the financial costs of adding or maintaining new facilities that could increase use and activity? Or what are the life span costs relative to increased use and additional physical activity?

A recent study provides estimates of physical activity intensity (calories burned) for different park areas. The number of people in each area and the cost of constructing each facility are combined into an index that measures the cost of the facility relative to PA intensity.  This allows park areas to be ranked based on their cost and ability to promote physical activity.

Answers to these questions can provide objective information to park officials, policymakers, and citizens to help them make more informed decisions about park facilities construction to promote active lifestyles. But to date, no ideal mathematical formula exists that tells us what to put into a park to “make” people active or healthy or to optimize a park’s design for achieving multiple goals. The prospect of a formula or rubric that would roll up all of the desired outcomes from parks and greenspace into a single model of coefficients and variables is alluring. Ideally, a park system would be expected to yield a set quantity of energy expenditure per capita, as well as other benefits.

Collaborating with scholars from North Carolina State University, Design Concepts Principals Robby Layton and Carol Henry contributed to this document that blends evidence-based research with real-world practical experience, offering guidance to planners, policymakers, and others involved in providing parks and promoting public health.
