Stormwater discharge is a vital resource that provides many environmental and recreational benefits. In urban areas like Joint Base Lewis-McChord (JBLM), protecting stormwater quality from pollutants is essential. Most common pollutants from urban areas are trash, bacteria, pesticides, and POL (Petroleum, Oil, Lubricants). These pollutants can impact the quality of stormwater and ultimately enter a nearby waterbody. JBLM's stormwater system is complex and preventing stormwater pollution is crucial to maintaining water quality for everyone and the environment. JBLM's Stormwater Team goals include preventing illicit discharges from harming the environment and improving the quality of stormwater leaving JBLM's property.

Design/Construction
The Joint Base Lewis-McChord's (JBLM) Stormwater Design Guidance document was created to establish design and analysis criteria for all types of development activity to stay in compliance with JBLM's Municipal Separate Storm Sewer System (MS4) Permit. Stormwater Design Guidance is required to be used in conjunction with the 2024 Stormwater Management Manual for Western Washington (SWMMWW) and the Aviation Stormwater Design Manual (Aviation Manual). The JBLM Stormwater Design Guidance describes the requirements that designers must meet when developing sites will disturb more than 5,000 square feet of ground. This includes creating a site-specific Drainage Plan, Stormwater LID Form, and developing a project Stormwater Pollution Prevention Plan (SWPPP).
Projects that disturb more than 1 acre of ground must submit a NO1 to the Environmental Protection Agency (EPA) for CGP coverage, develop a CGP SWPPP, a site-specific Drainage Plan, and fill out a Stormwater LID Form. Templates and guidance documents can be found below.
