Information has been received that the Omaha Parks Recreation and Public Property department is "actively working" the issue regarding the property boundary on the Iowa side of Carter Lake.
A surveyor "has been commissioned" to determine the boundary, which is expected to "take 4 to 6+ weeks to complete," according to a city staffer that works with the Omaha City Council. They had been sent an email asking that this boundary issue be looked into, to ensure that the actual property line would be determined. There had been no reply from the mayor's office or Park's officials, despite emails and a phone call.
So it appears that details on the property boundary will be be available by spring!
