Residents are strongly encouraged to identify higher ground where equipment can be safely and securely stored. For citizens of Dell Rapids, an option can be the old Shopko parking lot located at 1208 N. Highway 77 in Dell Rapids. Please note, the parking lot is not monitored so the responsibility to secure equipment temporarily stored there is the equipment owner’s responsibility.
14. How do I clean up my dwelling after flooding?
Personal protection equipment (rubber boots, rubber gloves) is highly recommended when cleaning up water damage. A disinfectant mixture of 1 cup bleach to 1 gallon of water should be used. When in doubt about the safety of your residence, you should contact a professional.

Any member of the public with flood-related property damage in Renner, Dell Rapids, or within the Minnehaha County boundaries should dial 2-1-1 to complete a damage assessment over the phone.
16. Why shouldn’t I drive through a flooded roadway?
Besides immediate danger to yourself and others in your vehicle, driving through a flooded street creates waves and wakes. The additional pressure created by water movement adds significant stress to sand bags protecting others’ homes and personal property.
