Stormwater Management Plan Document Library

The Stormwater Management Plan (SWMP) program implementation requires numerous codes, ordinances policies, procedures, guidance manuals, checklists, forms, mapping, and other related documents. Throughout the city's current SWMP, the relevant documents are noted within each program category or best management plan (BMP). The referenced documents have been compiled into this SWMP document library.

Please note that this page is continually being updated. You may reach out to Marcos Kubow to request information or ask for assistance at 971-204-4672 or via email.
