Seattle announced a “Low-Pollution Neighborhood (LPN)” pilot program that will bring infrastructure upgrades aimed at increasing walking, biking, and transit in four parts of the city .

As Ryan Packer explains in The Urbanist, the city is joining others like London and Barcelona in creating neighborhood-scale carbon reduction programs. “So far, details on what strategies could be implemented in LPNs have remained high level, ranging the gamut from electric vehicle charging infrastructure to curbside plazas and pedestrian streets.” The city will develop specific strategies this year, with the goal of implementing changes in 2028.

Examples of possible tools include pedestrianization similar to Barcelona’s superblocks, bike lanes, access to transit, and stormwater infrastructure, based on the needs of specific neighborhoods.
