Background and Connection to Redmond Paired Watershed Study
King County has selected Redmond’s application for the King County WaterWorks grant to fund increased street sweeping in the Tosh Creek Watershed. Tosh Creek Watershed is identified as a priority watershed within the Redmond Watershed Management Plan. Tosh Creek Watershed is in southwest Redmond, please see the Watershed Map in Attachment 3.
Increased street sweeping within the Monticello Creek Watershed in 2017-2019 was shown to improve water quality of Monticello Creek by reducing the total copper and suspended solid concentrations within the creek. Staff will leverage water quality sampling from the Redmond Paired Watershed Study (RPWS) to determine if increased street sweeping within the Tosh Creek Watershed will also improve water quality.
The RPWS is designed to measure the effectiveness of actions taken by Redmond’s Stormwater Utility and King County to restore urban streams on a watershed scale. This is done by analysis of monitoring data collected in six watersheds within Redmond, including the Tosh Creek Watershed. Council was provided with an update on RPWS findings during the June 1, 2021 staff report. RPWS data collected from Tosh Creek will be used to determine the effectiveness of street sweeping to improve water quality.
Sustainability
This project supports Strategy N1 and N3 in the Environmental Sustainability Action Plan.
Additional Benefits
While not called out as a specific NPDES permit requirement, street sweeping helps Redmond meet permit obligations to prevent degradation of receiving waters (in this case, Tosh Creek) by keeping pollutants out of the storm drain, which discharges without any treatment to Tosh Creek.
This study in Tosh Creek will benefit the Puget Sound region by quantifying the benefits of street sweeping on in-stream water quality. Street sweeping is a cost-effective, readily available stormwater management tool that can be equitably served throughout a jurisdiction.
OUTCOMES:
If the King County WaterWorks grant is accepted, it will fund increased street sweeping on the 3.54 miles of public roads within the Tosh Creek Watershed, one of Redmond’s highest priority watersheds for restoration.
The grant will provide funds to:
• Increase street sweeping within the Tosh Creek Watershed from quarterly to monthly from October 2022 through September 2023. Internal staff will conduct the street sweeping on overtime.
• Increase street sweeping within the Tosh Creek Watershed to twice per month from October 2023 through September 2024. Internal staff will conduct the street sweeping on overtime.
• Analyze data (leveraged from the Redmond Paired Watershed Study) to determine if increased street sweeping had an impact of water quality within Tosh Creek.
• Create summary report of data analysis.
Additionally, funding from the Department of Ecology will be utilized to add the analysis of 6PPD-quinone (6PPD-q) to sampling conducted by the RPWS to determine the effectiveness of street sweeping at reducing the amount of 6PPD-q entering urban streams. 6PPD-q is released as car tires wear and has been found to be acutely toxic to Coho Salmon adults in freshwater urban streams. Little is known about this emerging contaminant and there will be great regional interest in the results of this study.
The required 10% in-kind match for the grant will be the City’s sweeper equipment costs calculated using FEMA rental rates, which include equipment operations and maintenance, fuel, insurance, and replacement rates.
COMMUNITY/STAKEHOLDER OUTREACH AND INVOLVEMENT:
• Timeline (previous or planned):
If the grant is accepted, residents within Tosh Creek Watershed will be notified of the increased street sweeping in September 2022.
• Outreach Methods and Results:
Postcards will be mailed to residents within Tosh Creek Watershed to inform them of the increased street sweeping.

Time Constraints:
The project is scheduled to begin in October 2022. If there are delays in accepting the grant, that could impact scheduled start date.
ANTICIPATED RESULT IF NOT APPROVED:
The RPWS uses the pooled resources from Phase I and II municipal stormwater permittees. There is great interest from the permittees to determine the effectiveness of a widely available and relatively inexpensive operational practice (street sweeping) to address water quality and 6PPD-q pollution. Information from this study can be used by Western Washington jurisdictions to prioritize stormwater management practices and enhance salmon restoration activities. By not approving this grant, Redmond will miss an opportunity to leverage the RPWS and assist the region with critical data for salmon recovery.
