City’s Environmental Initiatives
To address environmental concerns and promote sustainability, Simi Valley’s Environmental Compliance Division oversees several key programs:

This program ensures that businesses adhere to the city’s Sewer Use Ordinance, safeguarding the sewer system and treatment facilities from harmful discharges. Regular monitoring and inspections help maintain compliance and protect public health.
Stormwater Quality Management
Aimed at preventing stormwater pollution, this program ensures compliance with the National Pollutant Discharge Elimination System (NPDES) permit. Activities include public education, industrial inspections, and collaboration with countywide initiatives to monitor water quality.
Hazardous Materials Program
The city offers a Household Hazardous Waste Drop-Off Program for residents, facilitating the safe disposal of hazardous materials. Additionally, the program provides emergency response services and training to city employees on hazardous materials awareness.
Solid Waste Services
Dedicated to reducing landfill waste, the city emphasizes proper waste separation and recycling. Residents and businesses are encouraged to participate actively to minimize environmental impact.
Water Conservation
Implementing water conservation ordinances, the city promotes efficient water use through rebates, water-wise gardening tips, and educational resources, aiming to mitigate the effects of long-term water shortages.
By understanding Simi Valley’s unique climate and supporting these environmental programs, residents can contribute to preserving the city’s natural beauty and ensuring a sustainable future.
