After spending half a million dollars to fix approximately 50 rain gardens in Sunset Hill, the city plans to install its largest non-residential rain garden yet outside a Ballard church.
The City of Seattle spent nearly $2 million last year on rain gardens aimed at keeping runoff and sewage out of the Puget Sound. Ten blocks of rain gardens were installed throughout Ballard as part of a pilot project. But several months later Seattle Public Utilities (SPU) ended up tearing out one third of the gardens because neighbors either didn’t like them or they were creating nasty floods. Another third had to be fixed, which cost SPU an additional $500,000.
Despite the failures and costly repairs, the city is trying again. SPU will install the city’s largest non-residential rain garden – the Trinity Rain Garden – at Trinity United Methodist Church, 6512 23rd Ave. N.W.
The garden, designed by Back To Nature Design, LLC, will filter rain water from 5,000 square feet of roof area, 2700 square feet larger than the city’s largest residential rain garden. The rain garden includes native, food-producing plants and trees, as well as a rain water cistern for irrigating the church garden.
“Part of the mission of Trinity United Methodist Church is to be an advocate for social justice issues. Our Judeo-Christian tradition teaches us to be caretakers of the earth and in Seattle that means caring for our streams and Puget Sound,” says Pastor Kathleen Weber. “Installing a rain garden is the perfect reminder of our commitment to environmental justice and sustainability.”
SPU says they have now fixed the problems and worked out the kinks found during the first phase of the Ballard Roadside Raingardens project, and recent testing is helping make sure everything is working properly.
“Pilot projects are designed to learn how technology is going to function. Although we have used rain gardens in other projects around the city this is the first time we have used the technology to help control sewer overflows,” said PSU spokesman Andy Ryan.
The Trinity Rain Garden will be celebrated with a ribbon cutting and blessing on Sunday, September 30 at 1 p.m. All are welcome to attend.
“The city is pleased that Trinity United Methodist Church has chosen to participate in the RainWise program on such a grand scale. We look forward to installing more installations like it across Seattle,” says Spencer.
Currently, residents living in the Ballard, Windermere, Delridge, and North Union Bay CSO (Combined Sewer Overflow) basins are eligible to participate in the RainWise Program. Residents of these areas can receive rebates covering most of the cost of installing a rain garden or cistern. Plans are underway to expand the RainWise program during 2013 to eleven additional areas, increasing to 45,000 the number of rain garden eligible households in Seattle.
