-Builders Need to Inspect and Maintain Storm Drain "Socks" [Link]
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.
All construction sites must have on-site erosion control measures to prevent soil from washing away. The use of storm drain inserts is an added level of protection for water quality.
Stormwater Code standards for the use of the socks include the following:
For reference, see Seattle Public Utilities' director's Rule DWW-210, or the Stormwater Manual, Volume 2, Chapter 4, Section 4.3.3.
Any questions on active construction site drainage or erosion control measures may be referred to the SDCI Site Inspection Team at (206) 684-8600.
To help prevent flooding, the public is urged to clear clogged drains where it is safe and practical to do so. Flooding should be reported to Seattle Public Utilities at (206) 386-1800.
