The rain falling right now reminds us of what’s coming up Sunday afternoon in the Sunrise Heights and Westwood neighborhoods – the King County Wastewater Treatment Division‘s celebration of the completion of the Barton Combined Sewer Overflow Control project. 15 blocks now have roadside raingardens after two seasons of construction; a ceremonial ribbon-cutting is planned at 1 pm Sunday at 32nd SW and SW Kenyon, and then from 1:30-4 pm, tours will be offered of “three recently planted blocks.” It’s also a chance to get updated information about the project, including the ongoing RainWise program, offering incentives for people in the target area to install rain gardens and/or cisterns. This project has been much-discussed, going all the way back to early meetings six years ago, so now that it’s done – whether you’re coming to the celebration or not – the county’s offering a survey for feedback – find it here.
