MEETING SUMMARY Weldona Flood Hazard Mitigation January 9, 1998 Overview: On Friday, January 9, 1998 a meeting and site visit were held in Weldona to discuss flood hazard mitigation alternatives for the community. The CWCB met with interested parties to review alternatives and come up with a recommended mitigation plan. Meeting Attendees: Mark Arndt Joe Baltazar Darrell Graham Dick Earl Kevin Kuretich Tom Brownin Dave Darlin Ella R. Bart Woodward Rick Lorenzini Key Results: The following bullet items summarize the key results of the meeting and site visit: · Based on input from County officials and other meeting attendees, the preferred mitigation alternative consists of the following: 1. Construct a dike/channel system at the north end of town to protect Weldona from a lOa-year flood event. The dike will begin at hwy 144 on the west end of town near CR 9, and will continue east and tie into to CR 9.5 near the high school. CR 9.5 will be elevated from the point of the dike tie-in north to the first bend in the road. The elevated road will act as a north-south levee to keep flows on the west side of the road. 2. Construct box culverts or a bridge under hwy 144 near CR 9. The opening of the culverts or bridge should be 3 to 4 feet high and as wide as possible. Attempt to construct the largest crossing possible for around $100,000. The lOa-year flows from the dike/channel system will likely overtop the highway, and that is acceptable to CDOT and the County. 3. Construct a lOa-year capacity channel downstream of the hwy 144 crossing. The County would like to purchase the farm land south of hwy 144 and west of Grove Street. The flood channel could go directly through this land to the South Platte River. The County recommended that the railroad embankment be open-cut to save the cost of
