This new underground vault will be a regional stormwater facility designed to capture and slowly release stormwater that drains to nearby creeks, reducing erosion and flooding. Over the years, as surrounding property develops in Overlake, park facilities are proposed to replace the parking on top of the stormwater vault. The development of this park would occur in the future with other neighborhood redevelopment. In the meantime, parking use will continue by the owner of the property.
Project Update: December 2013
Phase 1 work is now complete. The two projects that rerouted existing power and stormwater utilities around the proposed stormwater vault footprint are in place and operational.
In Phase 2, the Overlake Village South Detention Vault project will construct a 6 million gallon stormwater vault in the east parking area of the Sears site. The south vault is proposed to be operational by the end of 2014, with construction occurring over spring/summer/fall 2014. A new parking area will be constructed on the vault lid the following year in spring/summer/fall in 2015.
NE 20th Street will be open during the day with lane restrictions. This means that traffic levels on other arterial roads in the vicinity of the project likely will increase during the construction periods. This work will occur primarily during the day time with the possibility of some night work.

The City begins constructing a below-ground large stormwater detention vault this spring in the Overlake Village neighborhood. The project site is located in the east parking lot of the Sears store near NE 20th Street and 148th Ave NE. The project will include restoring the parking area above the new vault lid.
