September in Riverside means the pace picks back up. City Hall is hitting the road with the Ward 1 Townhall Tour, Heritage House is getting ready for moon cakes and lantern light, and a stretch of Orange Street is about to become an outdoor gallery. Add in a stacked run of live music, a crosstown soccer rivalry with real stakes for the first time, and more, and you've got a month worth circling on the calendar. Here's what's on our radar.

Civic & Community

Ward 1 Townhall Tour — City Hall is hitting the road this month. Catch the Senior Townhall on Tuesday, September 1 at 11 a.m. at Stratton Community Center at Bordwell Park, or the Business Townhall on Wednesday, September 2 at 2 p.m. at the Greater Riverside Chambers of Commerce. Come with your questions, leave with a few new neighbors.

Water Smarts 101 — Western Municipal Water District's quarterly workshop returns Saturday, September 19 from 10 to 11:30 a.m. Learn how to trim your outdoor water use, tighten up irrigation, and swap thirsty turf for something more climate-friendly. Free, but space is limited, so register ahead.

Arts & Culture

Orange Street Mural Unveiling — The Museum of Riverside and Division 9 Gallery are turning a construction fence into nine artist-designed panels along the Orange Street Pedestrian Walkway.

Moon Festival — Heritage House marks the harvest with moon cakes, lantern light, and lion dance on Friday, September 25 from 6 to 8 p.m. Expect storytelling, Chinese calligraphy demos, and a visit from UCR's astronomy club for some moon viewing of the celestial kind. Free to attend.

Butterfly Mosaic Workshop — Mission Inn Foundation's mosaic series continues Sunday, September 13 from 10 a.m. to 2 p.m. This round, you'll build a flowerpot instead of a stepping stone. $100 gets you all materials, a light lunch, and a few hours of hands-on creativity. No experience needed, but spots go fast.
