Larchmont District Green Infrastructure Project

Project Updates

Larchmont District Green Infrastructure Project is set to begin the week of June 19th, starting on 88th Street just south of the school.  It will mostly consist of utility work for the first 4-6 weeks before moving to road, sidewalk, and landscaping.  Please continue to follow along for project updates.

Project Overview 

 

The Larchmont District Green Infrastructure project is intended to improve neighborhood streets, fix drainage problems, and protect Puget Sound from polluted runoff through the use of permeable pavement. Permeable pavement allows rainwater falling on streets to soak into the ground, and eventually to the groundwater.  

The Environmental Services Department received a grant from the Washington State Department of Ecology and has partnered with the Public Works Department and Tacoma Water to replace the streets and utilities highlighted on the map below.  

 

With support from these partnerships, the project is planning to replace and/or install the following:                        

  • Permeable pavement (also known as pervious asphalt)  
  • Impermeable pavement (also known as standard asphalt)  
  • Continuous sidewalks  
  • Additional street trees 
  • Bike sharrows 
  • Street drainage  
  • Sewer pipes 
  • Drinking water pipes

Upon completion, the typical roadway and sidewalk will look similar to the graphic below.

(Streets may differ slightly from what is shown.)

  


Why permeable pavement?  

Replacing 18 blocks of failing residential streets with permeable pavement will improve the driving surface and help with water quality by infiltrating rainwater from the road surface. Currently, rainwater that is collected on the road surface in this neighborhood flows into catch basins, is piped to Flett Creek, Chambers Creek, and ultimately to Puget Sound. When this untreated rainwater (also known as stormwater) is piped to these bodies of water, it carries harmful pollutants from cars and human activities and discharges these pollutants into our water.  This has a negative effect on plants, animals, humans, and the entire ecosystem.   

The permeable pavement installed as part of this project will infiltrate 28 acres of stormwater, rather than collecting it in a piped system. This infiltration process will allow pollutants to be filtered out by the soils and allow clean stormwater to combine with the groundwater, which will help recharge the South Tacoma Groundwater Aquifer.  This aquifer is used by the City as a supplemental source of drinking water.
