Two capital projects at each end of the Indian Meadows Greenway will be constructed together. The first project is the reconstruction and improvement of stormwater infrastructure that spans between Boones Ferry Road and Siuslaw Lane, which serves as a significant collector of stormwater conveyance from Boones Ferry Road and areas east of Boones Ferry, including Talawa Drive, Arapaho Road and Iroquois Lane. Water is conveyed into the Indian Meadows Greenway, which provides natural stormwater collection and conveyance. The greenway ends at the west end of Coquille Drive, where a second project is proposed to reconstruct failing pipe and rehabilitate slope that has become eroded and unstable. Siuslaw Lane Stormwater Quality Retrofit: the existing infrastructure that conveys stormwater into the Indian Meadows greenway is failing and needs to be reconstructed and improved to provide enhanced stormwater quality treatment. Existing corrugated pipe has deteriorated and is no longer functioning correctly: 350 feet of 30-inch pipe and 100 feet of 48-inch diameter pipe will be replaced. A new water quality manhole will be added and existing catch basins (3) and manholes (2) will be replaced. The two outfalls into the greenway will be replaced, and grading will be completed to allow the existing open conveyance of the greenway to serve as a 500-foot long bioswale. 99th/Coquille storm line reconstruction: the existing corrugated metal pipe has deteriorated so severely that the pipe must be dug up and reconstructed. Project will consist of replacement of 300 feet of 30-inch pipe. The west end of the segment of pipe is an outfall that drains into a natural collection area. The existing pipe outfall has eroded the hillside; bank rehabilitation will be required. The outfall will be reconstructed and rip rap added to stabilize bank and slow runoff. FY-2023-2028 As of August 18, 2023, the project is in the City of Tualatin, Capital Improvement Plan for 2023/24-2027/28. Project is expected for the FY23/24. *Project information has been obtained through a public capital improvement plan (CIP). A CIP is a financial schedule for short- and long-range projects which is updated regularly. Information listed in the CIP often evolves based on funding availability and the project details, including timeline and value, are subject to change. The content management team will continue to pursue additional details as they become available.
