City of Kellogg Stormwater Management Upgrades (Phases 1, 2, and 3) 

Project Sponsor 

City of Kellogg 

Purpose  

The purpose of this project is to improve stormwater management at the city of Kellogg’s stormwater outfalls.  

This project includes several phases. In Phase 1, the city will work to improve stormwater management at the city of Kellogg’s stormwater outfalls—the point of discharge into a stream, river, or other water body—at Hill Street, Bunker Creek, and North Kellogg. By reducing the amount of stormwater that flows through these outfalls, the city aims to reduce the volume of metals, phosphorus, and other pollutants that eventually enter Coeur d’Alene Lake via the Coeur d’Alene River. The outfall upgrade at Bunker Creek will also add additional greenspace to the Trail of the Coeur d’Alenes. 

In Phase 2, the city plans to address stormwater at Government Gulch by restoring and improving swales and ponds for better stormwater retention. The city will also focus on work in Southeast Kellogg, including upgrading existing stormwater channels, sediment basins, and dry wells. This phase includes the purchase of a vacuum truck to clean out stormwater systems.  

The vacuum truck has been delivered and is being used by city staff to perform much-needed stormwater maintenance activities. 

After addressing known stormwater needs, the city will utilize Phase 3 to identify remaining needs and implement improvements to the stormwater management system. This funding will allow the city to conduct a comprehensive assessment, document areas in need of installation upgrades, and select the most cost-effective technologies to mitigate stormwater runoff. 

Funding 

This project received the following awards from Governor Little’s Leading Idaho initiative:

• Phase 1:  $570,000 
• Phase 2: $1.1 million  
• Phase 3: $670,000  

Status

Phase 1 – The three project areas, including Bunker Creek Bioswale, South Hill Street Continuous Deflective Separation structure, and North Hill Street inlet modification and filters are complete.   

Phase 2 – The vacuum truck has been delivered and is now in use. All other Phase 2 activities are in the planning and design stage with construction projected to occur this summer. 

Phase 3 – Investigative and work is scheduled to occur this summer. 

Outcome 

This project is estimated to reduce phosphorus inputs to the Coeur d’Alene River by over 700 pounds annually.
