Oregon City Council on Monday will consider signing a $60,000 contract with Saneholtz & Associates, LLC, to survey Otter Creek.
Council in April had agreed to a $70,000 contract with the company to conduct drainage studies of Amolsch Ditch, Amolsch-Driftmeyer Ditch and Wolf Creek.
"Now we want to include Otter Creek for the same general things we are checking out the other ones for," said Mayor Marge Brown at a committee of the whole meeting last Monday.
"If you look at the scope of services," said Public Service Director Paul Roman, "this work is very similar to what we have already approved with Saneholtz in terms of providing a professional survey for Wolf Creek and Amolsch Ditch."
The work will include a topographic survey, which will help in making decisions on how to improve drainage capacity, said Roman. It would also include sediment removal or widening of the ditch.
"We do have FEMA maps for Otter Creek and we do have some data, but when you look through what FEMA has established as topographic, it's all based on 1976 data," said Roman.
"When you look at that, the valley in which Otter Creek exists is still pretty much true. But the actual flow line of Otter Creek is what I question in terms of sediment buildup in areas. The FEMA maps go only so far in detail," he said.
"I look at what we currently have, and then I looked at what would help us, and that's how this scope of work was laid out. It's really more basic information. But it's a little more difficult to survey Otter Creek because of the number of trees," he said.
Roman met with Toledo Edison on Friday and got permission to go into certain sections of Amolsch Ditch, between Dupont and Bay Shore roads, to do some clearing.
"We use this data to find humps in the flow line. If we remove certain spots, we know that would improve drainage," said Roman.
"I had the opportunity to observe Otter Creek today," said Council President Mike Sheehy. "We have deer and fox, and a half dozen other four legged animals out there, and beautiful wild songbirds, and they're all drinking out of the water there, all thriving in that marshy wetlands. The more we can find out about it and make it better, make it cleaner, I'm all for it."
