The sanitary sewer improvements include 9,300 linear feet of sanitary sewer, demolition of Pump Station #13, and connection of the Pump Station #13 sanitary sewer service area to the new VenturePark sanitary sewer system.
The project is funded 100% by the Benefit District and 0% by City at large. The improvement district includes all property within the plat and will be assessed based on the proportionate share of square footage of each tract.

As a result of unanticipated site conditions, the project has experienced delays, piping realignments, and additional work to remove existing material. City staff has reviewed and recommends approval of Change Order No. 1 in the amount of $112,197.42, which includes the following:
· Removal of transite/HDPE pipe
· Repair of existing stainless lines not shown on plans
· Additional labor and pumping due to buried storm drainage piping not shown on plans
· Additional labor and materials for trench stabilization and rip-rap at creek crossings
· Additional labor, material, and restaking for realignments of the sanitary sewer around electrical substation, RCB, and landfill areas
