Working with the city of Bothell in an effort to improve safety and traffic conditions, a new traffic signal has been installed by Phoenix Development Corporation at the intersection of 228th Street Southeast and 31st Avenue Southeast as part of a new residential development. Phoenix has four new residential developments (approximately 140 homes total) in the area of the 228th and 31st intersection and funded both the design and construction of this $440,595 project.

The developer was required to assess the impact of new trips that would generate from proposed new residential developments. That assessment indicated that traffic operation and safety levels would be unacceptable for this intersection. Both safety and traffic operation levels will significantly improve with the addition of this signal.
