Cedar Valley Nature Trail Improvements // 2020–25

• Trail currently closed from 10th Street NE, along McLoud Run, and south to the Cedar Lake Loop located at the northwest corner of Cedar Lake
• Detour established along 10th Street NE
• Flood control in this area will include a new levee and trail system west of Shaver Road and south of McLoud Run, with the trail built on top of the levee (similar to the Sinclair levee).
• The levee and trail system will include amenities such as a trail parking lot, pedestrian benches, and scenic viewpoints.
• When all flood control measures are completed in this area, it will wrap around Cedar Lake, tying into high ground at I-380 near J Avenue, and will protect homes and businesses threatened when the Cedar River backs up into McLoud Run and Cedar Lake

• Will eliminate the complex geometry at the intersection where 1st Street NW, E Avenue NW, F Avenue NW, and the I-380 off-ramp all come together
• The realignment will be a simplified, more intuitive design, and will accommodate permanent flood control measures such as a levee and pump station
• Reconstruction 1st Street NW from 1st Avenue W to I-380

• Located underneath I-380 on east riverbank
• Roller gates similar to 16th Avenue SE
• Signal removals at E and F Avenue: precursor work to gate installation (2021)
