Stories about Getting to Clean Water: Shoreline’s Aurora Corridor Improvement

By Diane Dent, Water Quality Stories Lead, Water Quality Program

A raingarden swale along Shoreline’s Aurora Avenue improvement area.

Introduction

A three-mile stretch of Aurora Avenue (Highway 99) between North 145th Street and North 205th Street in Shoreline, Washington, had problems. Before the city began making improvements here much of the area lacked sidewalks, and the wide roadway transitioned directly into parking for businesses along both sides of the street. The Washington State Department of Transportation said this corridor was one of the most dangerous stretches of road in the state.

Problem

Prior to the improvement project buildings, roadways, and parking lots covered approximately 97 percent of the area in hardened surfaces. During storms or heavy rain events, stormwater runoff from these surfaces flowed directly into nearby waters with little to no water quality treatment.

Milestones and outcomes

The city installed a series of low impact development (LID) structures that will help reduce stormwater volume, reduce pollutants from discharging into nearby waters; save money; improve community aesthetics; and improve air quality while reducing the heat island effect.
