Project: South Park roadway and drainage partnership
Client: Seattle Public Utilities

The South Park drainage and roadway partnership project in the city of Seattle is an example of effective collaboration between city entities and designers. Osborn Consulting played a pivotal role as the prime consultant and stormwater lead, contributing to the project’s success.

The project addressed chronic flooding, safety concerns and poor roadway conditions in the South Park neighborhood. The team utilized earthquake-resistant ductile iron pipe for the water main, enhancing resilience in a liquefaction zone. Additionally, geogrid technology reduced pavement section depth, benefiting a neighborhood with subpar pavement subgrade. Collaboration between Seattle Public Utilities and Seattle Department of Transportation, along with extensive community input, resulted in a project that significantly improved the area’s infrastructure and quality of life.

According to Jason Sharpley, project manager for Seattle Public Utilities, “This project installed more than 4,000 (linear feet) of new public storm drainage system, almost 90 new street trees, and approximately 1.5 lane miles of new right of way improvements, including sidewalks, trees, and roads designed for industrial uses. Today, the neighborhood is safer with roadway and sidewalk improvements, healthier with the addition of trees and vegetation, and more productive with the reduction in frequency of flooding events.”

This project demonstrates how addressing complex challenges, such as flooding, poor infrastructure, and environmental concerns, requires careful planning and stakeholder engagement. The successful fulfillment of client and community needs, as well as sustainability considerations, make this project a model for future partnership projects in Seattle. The project’s completion has transformed the South Park neighborhood, making it safer, healthier and more resilient.
