What & Why?

What's happening now?

April 12

Construction activities at the Seward Park site:

The contractor will be on-site this Saturday, April 15, to lay the first coating for the new tennis courts. This work is weather-dependent, and the contractor wants to take advantage of the weather forecast. Work hours are expected to be 9 a.m. to 5 p.m. The new tennis courts will need several coatings and about 30 days to cure before they are open to the public later this spring.

The site fencing will be removed by Friday, April 14, but the gates to the tennis courts will remain locked. As of Wednesday, April 19, the contractor will no longer have a daily presence at the site, but will return periodically through April to complete several weather-dependent tasks such as the tennis court surfacing.

Project goals and benefits

This project will reduce the frequency of sewage overflows into Lake Washington to no more than one per year per outfall (on average). SPU plans to complete two new underground storage facilities in North Henderson to store excess combined sewage and stormwater during major rain. The underground storage facilities are in the following locations:
