    Carson City Stormwater Laws and Regulations

    Carson City regulations are compliant with the Nevada Division of Environmental Protection Bureau of Water Pollution Control Stormwater Discharge Permit Program requirements.

    Excerpt- Carson City Storm water & Flood Plain Management

    If the property is privately owned, the personal owner, developer, homeowners association or property manager designated by property owner is responsible for all maintenance needed for the drainage and storm water facility within property lines.  The City is not responsible for the maintenance of private storm water facilities, and the storm water utility funds are not used to maintain private systems.  City staff will periodically inspect private facilities to ensure that the system operates properly and maintenance is done.

    The Storm water Utility Fund is used to construct, operate and maintain the City’s flood protection, storm water infrastructure and protect water quality.

    Why is it important to invest in the storm water system? There are three primary reasons why capital investments are necessary to manage storm water today and into the coming years.

    1. Carson City’s population has increased since the original storm water systems were installed, resulting in new houses, streets, parking lots and other structures to serve a larger population. These hard surfaces repel rainwater, resulting in an increase in the amount of storm water that must be managed.
    2. New regulations developed to address water quality and pollutants moving through storm water into rivers and streams require that Carson City put in place structures such as filters, water quality ponds and wetlands to reduce or remove pollutants prior to their release into water bodies and improve water quality.
    3. Much of the infrastructure in Carson City was installed many years ago and is in need of repair or replacement. In addition, older systems often require more frequent maintenance.

    The approved stormwater rates became effective on July 1, 2021 and are as follows:

    • Single Family Residential $ 6.29 – $ 8.79
    • Group Impervious Area Properties $ 30.00 – $60.00

    Excerpt- Carson City Code of Ordinances

    12.19.080 - Requirement to prevent, control, and reduce storm water pollutants by the use of best management practices.

    The department shall adopt requirements identifying best management practices for any activity, operation, or facility which may cause or contribute to pollution or contamination of storm water, the storm sewer system, or waters of the United States. The owner or operator of a commercial or industrial establishment shall provide, at their own expense, reasonable protection from accidental discharge of prohibited materials or other wastes into the municipal storm sewer system or watercourses through the use of these structural and non-structural BMPs. Further, any person responsible for a property or premise, which is, or may be, the source of an illicit discharge, may be required to implement, at said person's expense, additional structural and non-structural BMPs to prevent the further discharge of pollutants to the municipal separate storm sewer system. Compliance with all terms and conditions of a valid NPDES permit authorizing the discharge of storm water associated with industrial activity, to the extent practicable, shall be deemed in compliance with the provisions of this section. These BMPs shall be part of a stormwater pollution prevention plan (SWPP) as necessary for compliance with requirements of the NPDES permit.
