June 8th marks World Oceans Day – which, as everyone knows, is a universally celebrated holiday in which ocean-themed decorations abound as far as the eye can see in stores, and we all get the day off from work to celebrate the majesty of our beautiful marine ecosystems!
Ok, maybe it’s not that ubiquitous – but it would be if we had our way. We love our oceans, from the crests of each wave to the dark abyss of mystery and wonder hidden far beneath the surface. For this World Oceans Day, we’re raising awareness about the impact of stormwater pollution on our marine environments and shining a light on the innovative green infrastructure solutions Los Angeles is implementing to mitigate runoff and protect our coastal waters.
Understanding Stormwater Pollution
Stormwater pollution is one of the most significant threats to marine ecosystems. When rain falls, water flows over streets, parking lots, and other surfaces, picking up pollutants like oil, trash, chemicals, and sediments. This polluted runoff often enters our storm drains and eventually into the ocean, harming marine life and disrupting delicate ecosystems.
Green Infrastructure Solutions in LA
Los Angeles and its residents are taking proactive steps to combat this issue by implementating green infrastructure solutions designed to manage stormwater sustainably. Here are a few examples:
- One Water LA. One Water LA represents a huge step forward for how Los Angeles handles its water. It is an integrated plan for managing water resources and facilities throughout the region which increases sustainability and health for both our environment and the people living in it. Of course, within the objectives for this in-motion plan are measures to both increase stormwater capture and reduce pollutants in our waterways. Both of these items will serve to help protect our oceans from stormwater pollution.
- Rain Gardens. Rain gardens are shallow, vegetated basins designed to capture and absorb rainwater runoff from impervious surfaces such as roofs and driveways. By filtering pollutants and allowing water to percolate into the ground, rain gardens reduce the amount of contaminated runoff reaching our oceans while simultaneously conserving water. Across LA, community and residential rain garden projects are launching, transforming urban spaces into green, sustainable areas. Check out our guide on how you can build your own rain garden!
- Bioswales. Bioswales are landscape elements designed to concentrate or remove debris and pollution from surface runoff water. These natural filters, often filled with native plants, are strategically placed along roadsides and in parking lots. They play a vital role in preventing pollutants from reaching our oceans. LA has been actively incorporating bioswales into urban development projects to enhance stormwater management.
- Stormwater Capture Projects. Los Angeles is investing in large-scale stormwater capture projects to address runoff more effectively. Projects like the LA River Master Plan and the Tujunga Spreading Grounds Enhancement are designed to capture, treat, and reuse stormwater, reducing the amount of polluted runoff entering our waterways and oceans. Additionally, don’t forget about LA County’s Safe Clean Water Program which is transforming how LA manages stormwater.
- Managing Industrial Waste. LA Sanitation’s Industrial Waste Management Division is here to ensure that wastewater is treated and reclaimed where possible. This division is responsible for the removal of substances such as foods, soaps, or waste from our water so that it can be reused for non-drinking purposes and doesn’t simply flow into and pollute our oceans.
Community Involvement
Community involvement is crucial to the success of these green initiatives. LA Sanitation & Environment (LASAN) regularly hosts workshops and provides resources to educate residents on how they can contribute to stormwater management efforts. From installing rain barrels at home to participating in local clean-up events, there are numerous ways for Angelenos to get involved and make a difference.
This World Oceans Day, let’s come together as a community to protect our precious marine ecosystems. By understanding the impact of stormwater pollution and supporting green infrastructure initiatives in Los Angeles, we can make a significant difference. Whether you’re crafting a rain garden, exploring a local beach, or simply spreading the word, every action counts. Let’s ensure that our coastal waters remain vibrant and thriving for generations to come. Happy World Oceans Day, Los Angeles!
