Consideration and Approval of Engineering Services Contract with Cabbiness Engineering, LLC for maintenance and improvements for the Spring Creek Tributary 1, south of 2nd Street running through the Willowood Addition; $39,000.

This design contract will develop construction plans to address ongoing channel erosion between 2nd Street and the Willowood Lonsdale drainage structure and add additional scour protection immediately upstream of the concrete channel liner.  Also included is sediment removal at the downstream end of the concrete channel liner along with some grouted riprap repair for a storm sewer pipe that stubs into the channel.  The contract will include HEC-RAS modeling of the improvements and as-built after the construction to ensure there is no rise in the 100-year water surface elevation.

The Stormwater Drainage Advisory Board recommended approval of the design contract at the March  26, 2019 meeting.
