  • Storm Sewers


    Storm sewers in unincorporated Jefferson County are not mapped. If you need information about storm sewers that your surveyor can not determine, please follow these procedures:

    • If the storm sewer is located within a subdivision development built after 1998, contact Planning and Zoning at 303-271-8700. Otherwise, call the Transportation and Engineering main number at 303-271-8495. You can also complete an online service request form.
    • In either situation, it will help to know the name of the subdivision, or a nearby address or intersection, where the storm sewer is located. Subdivision names can be found on the county assessor's maps.
    • Ask to see the approved construction plans for the area of interest. As-built drawings are not typically available. You need to make an appointment to review the documents. Staff can make copies upon request.
