How to identify an IRWD employee If someone knocks on your door claiming to be an IRWD employee or contractor,

don’t hesitate to ask for identification. All IRWD employees carry staff IDs with photos and are required to show them on request. Many also wear uniforms with District logos and drive an IRWD vehicle.

Q: I noticed some graffiti at an IRWD

facility by my house. How can I report it? A: Glad you asked! IRWD has a graffiti hotline at 949-453-5535 to help us stay on top of tagging problems before they spread. Call this number to report graffiti and other nuisances at our facilities. When you call, be sure to note the location, including the street, intersection and address, if possible. Describe the surface the graffiti is on (block wall, pipe, etc.) and the type of paint or marker that was used. This will help our crews respond with the cleaning tools they need. Please provide your name and contact information so we can reach out if our crew has questions or can’t find the problem. Got a question? Email info@IRWD.com with “Ask Customer Service” as the subject line.

IRWD contractors should be able to produce information confirming they are authorized to do work in your neighborhood on behalf of the District. That work might include meter reading, construction, landscaping and temporary shutdown notifications related to new construction. No IRWD employee or contractor will attempt to sell you a product or service. If you ever have questions, call 949-453-5300.

Q: With summer approaching, my kids say it’s getting too hot to be outside. How can I add more shade to my landscape? A: You have several ways to make your yard more comfortable. Quick options include shade sails, which block up to 98% of UV rays and can be installed easily, or market umbrellas that you can reposition throughout the day. For kid-focused areas, playset canopies provide instant overhead shade. Or, consider a pergola or gazebo to create a permanent shaded zone. Pairing these with fast growing trees gives both immediate relief and long term cooling. For more ideas and inspiration, explore the full guide at your go-to resource, yardtopia.com .

California native corner Juan’s May plant: California bush sunflower California bush sunflower ( Encelia californica ) is a semi- deciduous perennial that grows quickly and brings an early burst of color to native plant or pollinator gardens. Known for its bright yellow blooms that appear from winter into spring, it attracts butterflies and bees and offers cheerful stems for flower arrangements. As the season progresses, the plant’s seeds become an important food source for birds. The plant’s dense, fibrous root system also makes it useful for erosion control on slopes and disturbed soils.
