Bioswales & Rock Swales & Detention Basin Maintenance in Southern California

At Seventy1 Environmental, we specialize in maintaining bioswales and rock swales in Southern California to ensure your stormwater systems function effectively and meet regulatory standards. These green infrastructure features slow, filter, and direct stormwater runoff naturally. Over time, bioswales and rock swales can become clogged with sediment, overgrown vegetation, or debris, which reduces their ability to filter pollutants and manage flow. Our team provides thorough inspections, vegetation management advice, minimal erosion control, and sediment removal to restore their proper function. Whether you manage a commercial property, residential development, or public space, our swale maintenance services are customized to fit your site’s unique drainage design and requirements.

We also offer expert detention basin maintenance services in Southern California. Detention basins temporarily hold stormwater and release it at a controlled rate to prevent flooding and erosion. Without proper upkeep, these basins can fill with sediment, become overgrown, or lose capacity, compromising performance and risking regulatory violations. Our team handles all aspects of bioswales & rock swales & detention basin maintenance—including sediment removal, vegetation control, and structural inspections—to ensure they operate correctly and remain compliant with local and state regulations.
