In September, 2013 flooding along the St. Vrain River caused flood damages to the Hokestra property. Damages included scour of the slurry walls, scour of the clay liner, scour to an existing wetland, scour to the riverbank, destruction of the concrete Rural Return Flow Ditch, and destruction of the bike trail along the river. On November 26, 2013, the BOCC returned a pass around that approved the recommendation to issue a change order to Hall-Irwin to repair the flood damages. The cost of the change order is $903,544.69. The backup documentation provided to the BOCC has been attached to this memorandum. Weld County Public Works recommends that the change order be approved in the amount not to exceed $903,544.69.

Before the project can resume and be completed,the flood damages to the ditch,slurry walls, and clay liner need to be repaired. In order to protect the Hokestra project from future flood damages, the river bank needs to stabilized and the wetland needs to be repaired. The unused bike path can be repaired at the discretion of the Board. Base Tactical has informed Public Works that the repair work is a reimbursable expense from FEMA. Public Works has communicated and worked with Base Tactical to prepare a summary of damages and a plan for permanent repairs. The contractor who is constructing the slurry walls,clay liner, and ditches has prepared an estimate for the repair work. The estimate to repair the flood damages and return the site to the condition that existed before the flood is approximately $900,000. According to Base Tactical,the contractor could be authorized to do the repair work with a change order to the existing contract. What options exist for the Board? (Include consequences,impacts,costs,etc.of options) Option 1: Approve the change order for flood damage repairs in order to protect Weld County's investment in the slurry walls and clay liner. Without repairing the flood damages to the concrete ditch,the two slurry walls, and the clay liner, the Hokestra project cannot be completed. Repairs to the wetland and to the riverbank will help protect the County's investment in the conversion of the gravel pits to water storage. Option 2: Do not approve the change order. The Hokestra project cannot be completed and the County will not be able to maximize the investment Without repairing the ditch,the County will have no conveyance system to return augmentation water to the river. Recommendation: Since the change order is a reimbursable expense for flood recovery,Public Works recommends that the BOCC sign the change order and authorize Hall-Irwin to begin repairs on the project.

Water from the Last Chance Ditch continued to flow into one of the cells for several weeks after the flooding event. The Hokestra Gravel Pit site is composed of several cells. Weld County was in the process of converting the various cells to water storage. There are 5 cells that are being converted to water storage. Cells 3, SE-1, and SE-2 were surrounded by a soil-bentonite slurry wall (South Slurry Wall). Cell 4 was surrounded by a soil-bentonite slurry wall (North Slurry Wall). Cell 2 was in the process of being lined with a clay liner(Clay Liner). There was also a concrete return flow ditch (Rural Ditch Return Flow structure)that had been constructed to convey water from the Rural Ditch into the North and South Slurry Walls. The return flow ditch extended from the Rural Ditch headgate to the Saint Vrain River. Flood damages to all of the above mentioned structures were sustained. The South Slurry Wall sustained damage to the southeast corner of the wall when the Rural Ditch overtopped and breached into the pit(see Sheet C-05). The North Slurry Wall sustained damage from the Saint Vrain River when it came out of its banks and flowed into and out of the cell. The majority of the damage to the slurry wall occurred in the northeast corner(see Sheet C-04). The slurry wall cap was eroded away and approximately the top foot of the slurry wall was washed out. In order to prevent the water that was flowing out of the cell after the flood waters receded from causing further damage to the slurry wall, the contractor was authorized to pump the water level in the cell down to a level below the top of the slurry wall. The Clay Liner sustained damage when the Saint Vrain River came out of its banks and the Last Chance ditch overtopped its banks and flowed into the cell. The majority of the damage happened in the northeast and southwest corners of the pit (see Sheet 2). The corners where the pit was breached were severely eroded by water flowing into the cell. The flowing water eroded into the clay liner. In addition to damage to the clay liner, the protective layer of material around the entire length of the cell was eroded. In order to stop the flow of water from the Last Chance Ditch from entering the Clay Liner,the contractor was authorized to remove a blockage from the ditch and to repair the breach. The floodwaters also scattered pipe that was being installed as part of a sub-drain. The contractor was authorized to gather the pipe in order to determine how much pipe had been lost or damaged. In the vicinity of the Clay Liner, there was also damage to a wetland slough that washed out, damage to a concrete walking trail, and damage to the streambank. The damage to these areas will need to be repaired. The Rural Ditch Return Flow structure was damaged in multiple areas. Approximately 855 feet of the structure was completely washed away (see Sheet CH1). Runoff from the surrounding lands and overflow from the Rural Ditch also damaged several shorter sections of ditch (see Sheets CH2-CH4). In these shorter sections of ditch, the ditch buckled and cracked due to the water flowing into the ditch. In some areas, one side of the ditch was partially eroded causing failures.
