Don’t let your candy wrappers come back to haunt our waterways! 🍬 You can help us scare away stormwater pollution with these simple tricks: 🧙♀️ Don’t pour potions, paint or chemicals down the storm drains. Visit the link in our bio for hazardous waste drop off sites! 🍂 Leaves can create a monster mess in the storm drain. When raking up fall leaves, remember to sweep them away from the street and storm drains by disposing them in the GREEN bin. 🗑️ Keep the spooky stuff away from our streets, storm drains and waterways by placing any trash directly into a covered bin. Together, we can help protect San Diego’s waterways from pollution nightmares. Think Blue, San Diego!

🤔 Did you know that one inch of rain falling on an average home’s roof produces about 620 gallons of rainwater runoff? 💧 Instead of letting rainwater go to waste, you can capture it with a rain barrel and use it to irrigate your garden. 🌿 Make every drop count! The @CityofSanDiego offers rebates for installing rain barrels, gutters, and downspout redirects to help you start harvesting rainwater at home. 🔗 Learn more and apply at: www.thinkblue.org/rebate-program/

Rainy season in San Diego is officially here! ☔ Now is the time to prepare your family, home and community for wet weather. Here’s how you can help protect your property and our waterways: 💧 Clear rain gutters: remove leaves and debris to prevent clogs and reduce the risk of flooding. ♻️ Secure trash and recyclables: pick up litter and make sure bins are tightly closed to stop waste from washing into storm drains. 🌿 Cover bare soil: use mulch to prevent erosion and reduce stormwater runoff in your yard. 💡Pro tip: Did you know @cityofsandiego offers rain gutter rebates and FREE mulch to help residents get #RainReady? 🔗 Learn more and apply at www.thinkblue.org/rebate-program/.

Thank you to the volunteers across San Diego who joined us on Coastal Cleanup Day! 💙 Together, we removed over 55,000 pounds of trash, litter and debris from our local environment. 🧹🗑 Clean water and clean beaches are made possible by clean stormwater.

Happy First Day of Autumn! 🍁 As the seasons change and the leaves begin to fall, remember to rake them up and dispose in a covered green bin! 🧹🍂 ➡️ 🗑️ When leaves enter storm drains, they release excess phosphorus and nitrogen into our waterways, contributing to water pollution and harming aquatic life. 🐟💧 They can also clog drains, leading to neighborhood flooding during storms. 🌧️ Remember to rake your leaves and dispose of them in a covered green bin to keep them out of storm drains and waterways!
