Storm Drain Insert Reminder
With the onset of the rainy season, SDCI is reminding builders working in Seattle to inspect and maintain any temporary storm drain inserts they have installed as part of construction projects. The inserts, also known as storm drain socks, are used on many construction projects to catch sediment not captured by other required construction-related erosion control measures.




What’s Happening with the Stormwater Code Update?
Our proposed 2021 Stormwater Code and Manual update is scheduled to be effective in July 2021. Our new rules will replace the current Stormwater code and Directors’ Rules, which are administered jointly by SDCI and Seattle Public Utilities (SPU). For more information, visit our Updating Stormwater Regulations web page. There are two public review periods and three public meetings coming up between now and mid-2021.
