City of Kellogg
Purpose
This project improves stormwater management at the City of Kellogg’s stormwater outfalls and consists of three phases.
In Phase 1, the city improved stormwater management at three outfalls (the points of discharge into a stream, river, or other water body. These outfalls are located at Hill Street, Bunker Creek, and North Kellogg. By reducing the amount of stormwater that flows out of 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 also adds 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 southeast Kellogg to upgrade existing stormwater channels, sediment basins, and dry wells.
In Phase 3, the city is identifying remaining needs and will be planning improvements to the stormwater management system with available funding. This Leading Idaho funding allowed the city to conduct a comprehensive assessment and document areas for installation upgrades. The City will select the most cost-effective technologies to mitigate stormwater runoff in as many of these areas as funding will address.
Funding
This project received the following from Governor Little’s Leading Idaho initiative:
- Phase 1: $570,000
- Phase 2: $1.1 million
- Phase 3: $670,000
Current Status
Phase 1 – Three project areas are complete: Bunker Creek Bioswale, South Hill Street continuous deflective separation (CDS) structure, and North Hill Street inlet modification and filters.
Phase 2
- Project Area 1—Government Gulch Channel Restoration. Design is at the 95% level. The goal is to finish design and obtain a bid in May 2025 for construction, scheduled for end of summer 2025 (low water season).
- Project Area 2—Southeast Kellogg. Design is at the 60% level. The goal is to finish the design in and obtain a bid for construction in coordination with the Government Gulch Channel Restoration project. Several common work items, such as earthwork, best management practices, and revegetation, can be conducted by the same company and provide a cost savings.
- Project Area 3—Supplemental Maintenance Equipment. The Vactor Truck was purchased and is currently used by city staff to perform much-needed stormwater maintenance activities. The city has cleaned over 25 storm catchments, 3 storm channels, and 2 miles of storm pipe.
Phase 3 – Outstanding Areas of Kellogg
- Task 1—System Investigations and Survey. Cleaning, video recording, and mapping of the investigation area’s stormwater system are complete. A survey of the inlets and surrounding areas is also complete.
- Task 2—Engineering Design. Project analysis and selection is underway. During April 2025, the selected phosphorus reduction projects will be presented to DEQ for comment. Bidding of projects is anticipated in summer 2025.
- Task 3—Construction and Final Reporting. Not started.
Outcome
This project is estimated to reduce phosphorus inputs to the Coeur d’Alene River by over 700 pounds annually.
