Center Lane Trees: A Traffic Calming Solution for Seattle's Aurora Avenue?

Seattle's Aurora Avenue, a major arterial notorious for its high speeds and frequent accidents, is facing a potential transformation. Could the answer to calming traffic and improving safety lie in something as seemingly simple as planting trees down the center lane? The proposal, currently under consideration by Seattle Department of Transportation (SDOT), is sparking debate and raising important questions about urban planning, traffic management, and the role of green infrastructure.

The Case for Center Lane Trees on Aurora Avenue

Proponents argue that center lane trees offer a multifaceted approach to traffic calming. The physical presence of trees naturally narrows the roadway, forcing drivers to slow down. This inherent design feature is particularly relevant on Aurora Avenue, where wide lanes encourage speeding. Furthermore, the psychological effect of a greener, more aesthetically pleasing roadway can also contribute to slower driving habits.

Studies have shown a correlation between green infrastructure and reduced traffic speeds. A 2021 study by the University of Washington, for example, found that streetscapes with increased greenery experienced a statistically significant decrease in average vehicle speeds.

Beyond traffic calming, center lane trees offer several other benefits:

• Improved Air Quality: Trees act as natural air filters, absorbing pollutants and improving air quality in the surrounding area. This is particularly beneficial along Aurora Avenue, which experiences high levels of traffic congestion and pollution.
• Enhanced Aesthetics: The addition of trees would significantly enhance the visual appeal of Aurora Avenue, transforming it from a concrete jungle into a more inviting and aesthetically pleasing thoroughfare.
• Increased Property Values: Studies have shown that properties located near green spaces tend to command higher values. Center lane trees could potentially boost property values along Aurora Avenue.

Challenges and Concerns

While the benefits are significant, the proposal also faces challenges. Concerns have been raised about:

• Maintenance: Maintaining trees in a high-traffic area like Aurora Avenue requires significant resources and ongoing upkeep. The SDOT would need to address issues like regular pruning, potential damage from vehicles, and the removal of dead or diseased trees.
• Accessibility: Ensuring adequate accessibility for emergency vehicles and public transportation is crucial. Careful planning and design are needed to prevent center lane trees from obstructing emergency response times or creating bottlenecks for buses.
• Cost: The initial cost of planting and establishing the trees, along with the ongoing maintenance expenses, represents a substantial financial investment.

The Road Ahead

The SDOT is currently evaluating the feasibility of the center lane tree proposal, carefully weighing the benefits against the potential drawbacks. Public input is crucial to the decision-making process. The community is encouraged to participate in upcoming public forums and provide feedback on this ambitious urban planning initiative.

Conclusion:

Center lane trees represent a creative and potentially effective solution for addressing traffic calming on Aurora Avenue. While challenges exist, the potential benefits – improved safety, enhanced aesthetics, and environmental improvements – make it a proposal worthy of serious consideration. The final decision will depend on a comprehensive cost-benefit analysis and careful consideration of all stakeholder concerns. The future of Aurora Avenue may depend on the success of this innovative approach to urban design. Stay tuned for updates as the SDOT continues its evaluation.
