Missouri and Big Sioux Rivers Update #7
To those of you who have left, thank you, we are glad you are safe!! This notice applies to all residential neighborhoods – all neighborhoods means all residential neighborhoods, including the Meadows, the Prairie and the Country Club. As of this notice (September 16, 2019), the NWS has not changed its Missouri River forecast and the resulting river levels will likely be to the top of our riverbank protection. We still advise relocation to ensure your safety.
The sanitary sewer system will only be shut down if the river overtops and/or breaches the protection in residential areas to preserve the infrastructure. We are making preparations to preserve the sanitary sewer system, but there will be a lot uncertainties in the short term, should a river overtop or breach occur.
We do not believe water, gas and electric will be impacted at this time.
The main concern is that the streets and other low lying areas will be inundated with water if there is a River overtop or breach. Examples of low lying areas would include the intersection of Bison/Levee Trail and Dakota Dunes Blvd, along with East/West Pinehurst and Dakota Dunes Boulevard.
In the event of overtopping or breach, notification will be sent out via text and email. Again, for your safety, we are advising all residents to relocate as soon as possible. This could last for five days or more, so prepare accordingly.
Dakota Dunes Community Improvement District Board of Supervisors are not confident that our protection can withstand the high water level a third time this year.
Residents should plug floor drains and turn off irrigation systems before you depart.
Turn off dehumidifiers, water softeners and air conditioners to protect your homes.
This relocation & River level are not expected to affect the Commercial areas or Dakota Dunes hotels, only the residential areas.
Please check on your elderly neighbors as they may not get notices electrically.
