Projects - Albany Street Stormwater Pond

Albany Street Stormwater Loop

The County is building a stormwater pond in Rochester near US-12/Main Street, to drain a 30-acre area of nearby streets. Most construction work will occur at 18133 Albany Street SW between September 2019 through December 2019.
Visit our Rochester area projects page to learn about other current or upcoming projects in the area.   


Rainwater will drain from nearby streets into the pond area, which will help clean the water as it gradually soaks into the ground before entering the underground aquifer and eventually the Black River. Over the course of a year, the pond will collect and soak in the same amount of water as a football field flooded 12 stories high! The project includes features asked for by the community, including landscaping, a walking path and crosswalk connecting to the nearby community park area, and amphitheater-style seating. Learn more in the project information sheet (PDF).


Drainage-related work is funded by a $1.1 million grant from the Washington State Department of Ecology. The property cost, and design and construction of community amenities is paid for by $310,000 of County stormwater fees. 

​Project Updates & History


Fall 2019 - Construction Begins

Construction began in September and you can already see the amphitheater style seating taking shape!

Fall 2017 - Project Design Begins

Street flooding near Albany St project siteIn 2017, Thurston County government asked members of the Rochester community to identify the location of stormwater flooding and standing water problem areas in their community. Those locations were added to this Rochester stormwater points map, which shows a purple triangle representing where the Albany Street Stormwater Pond will be located.  Community members also provided their preferences about pond designs and features.  

A design incorporating a Mima Mound theme (favored by 51% of survey respondents) was explored, but engineers discovered high maintenance costs for this approach. The County was able to incorporate many of the features desired by the community, such as a natural pond look (favored by 78% of survey respondents), walking path (favored by 75%), and seating on slopes similar to an amphitheater (favored by 22%). 

After reviewing community feedback, and conducting a thorough engineering analysis of the site, a concept for the pond was finalized to include as many desired community amenities as possible.
