    Stormwater Management Guidelines
    City staff will determine if the analysis for a proposed project may be limited in scope from the requirements set forth in the Stormwater Management Ordinance. Items City staff will look at in determining the level of drainage analysis required can be found in the Drainage Analysis Guidelines (PDF)
    Discharge Control
    The volume and quality of stormwater discharges must be controlled from developed sites, both of which are crucial requirements for protecting human life and property, maintaining overall water quality, and for creating more environmentally sensitive site design.  To ensure long term maintenance of installed storm water management systems a Covenant to Maintain Stormwater Management System is required to be executed and recorded at the Clay County Courthouse.
