Comments:
The award winning Mill Pond Development in Astoria has also used narrow streets. The site, a former lumber mill and brownfield has been rehabilitated to a neo-traditional development. In addition to the narrow 24-foot streets, the site contains street trees and oil/water separators.

Comments:
Many older neighborhoods were built with very narrow streets. On street parking can be allowed on both sides or restricted to one side to allow increased traffic.

Comments:
Many streets in the lower Columbia River region have not been improved with curbs and sidewalks. While pedestrian safety is compromised, these low traffic streets are often quite narrow and thus water quality friendly in that they minimize impervious surface.
