Change Order # 2, approved by Council in the amount of $178,373.94 on December 17, 2002, addressed additional height to the modular block walls, additional pipe rail safety fencing, and additional gabion baskets and gabion blankets to protect private property. Change Order #'s 3, 4 and 5, approved by Council in the amount of $66,173.50 on January 20, 2004, addressed field modifications to the channel to protect adjacent property from erosion and damage. Change Order # 6 addresses the placement of a concrete overlay on the interlocking concrete paver units on Creek 23, installed with this project between the Creekwood Drive culvert crossing and the oxbow on school property approximately 600 feet upstream. The original construction plans for Creek 23 included a concrete channel bottom upstream of the Creekwood Drive crossing. During the environmental permitting process for this project, the Corps of Engineers (COE) and other environmental regulatory agencies, required the concrete channel bottom be changed to interlocking concrete paver units. The intention was to allow ground water to percolate through the bottom of the improved channel, allow limited vegetation to grow in the channel bottom, and provide a wildlife habitat. The first significant rain event following the placement of the interlocking paver units resulted in uplifting and displacement damage to the channel bottom. This type of damage occurred on three different occasions with the contractor repairing the damage after each event. Due to the velocities and flow volumes through this channel, this type of channel bottom isnot a good choice for a stable channel bottom. The prospects for continued damage, excessive maintenance costs, and standing water due to displacement poses a health risk for the surrounding neighborhoods. City staff requested the COE allow a concrete slab to overlay the interlocking concrete paver units. The COE processed this request through the environmental regulatory agencies and approved the modifications. Staff recommends approval.
