    When do I need a permit?
    Sec. 2.213 (3)(a) - Private Property Drainage
    The property owner of any proposed development or redevelopment of commercial, industrial or multi-family residential property in the City that involves the drainage of surface runoff from impervious areas such as roofs, pavements, parking areas, and walks with a total surface area of one thousand (1,000) square feet or more shall apply for and obtain a stormwater discharge permit prior to the start of any construction, earth change, or other work on the project site.
    What can I discharge to the City Stormwater Drainage System (CSDS)?
