Nevada City has approved a one-time pilot program allowing the use of a biocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges. More kiln at the Nevada City Cohousing property. This decision follows three meetings of the Fire Safety Advisory Committee (FSAC), which explored ways to reduce hazardous fuel loads within city limits. The City Council approved the program on January 14, 2025, as part of the City’s ongoing fire safety efforts outlined in its 2022-2027 Strategic Plan.

While methods like chipping and green waste collection remain preferred, some areas present logistical or financial challenges. The controlled burning process of a biochar kiln offers an alternative, producing minimal smoke and containing fire within a metal structure. The resulting biochar can be used as a soil amendmentA soil amendment is any material added to the soil to enhance its physical or chemical properties, improving its suitability for plant growth. Biochar is considered a soil amendment as it can improve soil structure, water retention, nutrient availability, and microbial activity.   More. Only purpose-built biochar kilns are permitted under this program.

The pilot program follows strict safety guidelines in compliance with Nevada City’s Municipal Code. A Health and Public Safety Special Permit governs the use, approved by the City Council, Division Fire Chief, and Community Risk Reduction Officer.

The biochar kiln will be used once at the Cohousing property during the week of March 10, pending permit approval. A nearby water supply is available for fire safety. Neighbor outreach will occur the week of March 3. Additional information, including application details and staff reports, is available at NevadaCityCA.gov under wildfire preparedness.

This pilot program will help assess the viability of biochar kilns for future fuel reduction efforts while ensuring fire safety within the city.
