The boat ramp in Spanaway Park will close for six weeks starting Monday for pavement work designed to improve the quality of Spanaway Lake’s water.
In addition, Bresemann Boulevard South, the road through the park, will be shut down to through traffic for the nearly $1 million project.
The boat ramp will be closed through Oct. 24 so workers can replace pavement in the ramp’s parking area with pavement that will help filter out contaminants from storm water before it enters the storm water system.
Bresemann Boulevard will be closed to through traffic starting Monday while parking areas along the road are replaced with permeable pavement.

The road will open on the park’s northern side Oct. 25. Pavement work on the southern end is expected to be completed by November.
While the road is closed, the public can enter the 135-acre park from the northern entrance off Military Road South and park in Parking Lot A.
The park’s playground and walking trails will remain open during park hours while construction is underway, said Mike Halliday, of public works and utilities.
Storm water flowing over streets and parking lots in the park and nearby neighborhoods picks up pet waste, leaks from cars and other contaminants. Pollutants enter the storm water system and Spanaway Lake without treatment, harming the lake’s water.
The work is the second phase of a multiyear project intended to disconnect storm water runoff from the park to the lake, Halliday said.
Pervious pavement, paver stones, storm water filters and several large rain gardens – called bioretention areas – will be installed as funding is available.
Cost of the work starting Monday is $968,337, funded primarily by grants from the state Department of Ecology.
