POPLAR STREET WATER DRAINAGE IMPROVEMENT

DUDLEY PARK INCLUSIVE PUBLIC SPACE ENHANCEMENT

“Coupling” involves perceiving and capitalizing upon fortuitous connections that exist between often disparate events or ideas. Consider stormwater runoff and inclusive public spaces as two such ideas. Runoff challenges a city’s infrastructure. Conversely, people are drawn to water. Charlotte, New York, Chattanooga, and even Los Angeles have reaped the social and economic benefits that come from permeating their local waterways’ edges with useful public spaces. Seeking to create flexible public spaces that included all of its citizens, Athens, GA established a Greenway Trail along the flood-prone branches of the Oconee River as recreational pathways. It is possible to intervene at selected locations, with appropriate actions, that serve to improve the situations of seemingly disparate interests.

This project presents a solution that emphasizes the utility of public space because flexible, inclusive public space creates far-reaching, cascading benefits. Enterprise and companies seek to establish operations in attractive communities because these communities grow and draw a more productive, more creative class of people.A holistic solution seeks an effective stormwater management solution while simultaneously improving social, economic, cultural, and ecological community aspects.

CONCEPT RENDERING

When Peter Street floods at Branch Street, the diverted traffic serves to further congest Oconee Street, a gateway arterial roadway. The traffic problems cascade into social and economic problems at many levels. Likewise, the flooding has prevented any standard development of the most visible and accessible part of Dudley Park, the gateway at Mulberry Street and Poplar Street. Peter Street floods because the culvert under Poplar Street is too small to carry the lower Trail Creek Watershed drainage that a larger, upstream culvert, at Peter Street, is conveying. Water backs up, flooding the drainage stream that runs along Branch Street, which connects Peter Street and Poplar Street.

A creative solution to the occasional flooding is coupled with a non- standard approach to public space development, for this particular portion of Dudley Park.Installing a much wider, low profile culvert under Poplar Street economically solves the flooding issue, since the street grades will not have to change. Likewise, this is an opportunity to purposefully develop the Dudley Park gateway and extend the Greenway, laterally, into the community. This will open the door to create an Athens icon for a different generation.Satisfying the increasing citizens’ demand for public spaces that include accesses to shopping, schools, work, alternative transportation, and recreational venues is a critical political and economic issue.
