They City of Seattle will construct drainage improvements in west Broadview.
The 12th Ave NW Basin Drainage Improvement Project will improve the drainage system in parts of west Broadview with severe flooding issues.
SPU plans to reduce storm-related flooding by building new storm system improvements where there are none, to slow runoff and improve flows. The project may use a variety of tools in City of Seattle right-of-way along neighborhood streets to address flooding issues including:
Project design is just getting started and is anticipated to go through mid-2019.
SPU will work with the community throughout design to both share information and collect input on natural drainage systems.

The 12th Avenue NW Basin Drainage project will focus on reducing storm-related flooding by slowing runoff and improving flows, seeking to maximize benefits with available budget.
Following the outcomes of our program’s options analysis process that included community input, we are now focused on making improvements along neighborhood roads, in City-owned right-of-way. As we move through design, we will work to identify where proposed improvements may require property owners to clear any encroachments beyond their property boundaries that currently extend into the City’s right-of-way (e.g. fencing, landscaping, or parking). Without doing so, we won’t be able to meet our goals.
