We All Think Blue

For more than 20 years Think Blue San Diego has implemented innovative, proactive steps to stop pollution before it gets into storm drains. But to keep it that way, we must all dive in and do our part. Reducing stormwater pollution in our neighborhoods and communities is easy when We All Think Blue.

Happy #WatershedWednesday! 💙 🔦Today’s spotlight is on the Los Peñasquitos Watershed Did you know the Los Peñasquitos Watershed funnels rainwater through the communities of Poway, Scripps Ranch, Mira Mesa, Carmel Valley, and Del Mar before draining into the Pacific Ocean at the Los Peñasquitos Lagoon. 🌊 This watershed is home to more than 180 plant and animal species, several of which are endangered such as the American peregrine falcon, Quino checkerspot butterfly, Salt marsh daisy, California gnatcatcher, California least tern, and the Orange- throated whiptail. 🌱 🐦 Have you visited Los Peñasquitos Watershed?

April showers can either bring May flowers or unwanted #flooding. Plants, shrubs and trees slow rain hitting the ground and help soak up excess water, giving a little added protection from flooding. But greenery is sometimes hard to find in a metro area. Make the decision to stay protected and act today. www.floodsmart.gov/whats-covered #FloodSmart #FloodInsurance // Las lluvias de abril pueden traer flores de mayo o #inundaciones no deseadas. Las plantas, arbustos y árboles retardan la lluvia que llega al suelo y ayudan a absorber el exceso de agua, brindando un poco más de protección contra las inundaciones. Pero a veces es difícil encontrar vegetación en un área metropolitana. Tome la decisión de mantenerse protegido. ¡Actúa hoy! www.floodsmart.gov/whats-covered #SeguroDeInundación
