Order No. 4 exceeds City Manager Approval Authority - $778,949.00 Current design Location of sewer line is 5 feet west of the pavement in ROW maintained by residents Heavy landscaping,
new driveways, and existing retaining walls along the current alignment 13 properties along East Dove Road currently designed to flow to proposed sewer to be constructed along Creekside
Drive – sewer service would be delayed due to the proposed Creekside lift station issues Proposed Change Order No. 4 Proposed Changes move location of sewer into road but use original
directional drilling method to install if repairs are required to fix “bellies” or sags in the line, the road is dug up and this would avoid digging up resident’s landscaping and disturbing
retaining walls Neighborhood roads are still scheduled for paving reconstruction Proposed Change Order No. 4 Proposed Changes no delays to provide sewer service to the 13 properties
along East Dove Road – the sewer would be redirected to Royal Oaks to serve those properties once construction is complete Proposed Change Order No. 4 Proposed Changes approximately
700 linear feet of 12-inch water line to be moved into the street due to conflict with a 4-inch steel Atmos Energy gas line additional 2,000 square yards of sod along Primrose Lane
