Exhibit IRC North County Inline Pump Station Evaluation ATKINS • Updates to the 2015 wastewater hydraulic model will be required for Lift Station 203 Basin. Other updates to the hydraulic model are not included in this scope but may be recommended for future phases. • The hydraulic capacity of Lift Station 203 will be verified for current operation. Future capacities will be determined for the 2030 and 2045. Capacities between these modeled scenarios will be extrapolated from the model results for those years. • Field calibration of the hydraulic model is not included in this scope but may be recommended for future phases. • No site civil work beyond conceptual connections to the on-site force mains will be required as part of this phase of the project. No survey activities are included in this scope. Exclusions With the exception of the update to the hydraulic model of the Lift Station 203 Basin, the activities associated with this Work Order are conceptual in nature, intended to clarify the ability to create an in-line wastewater booster pump station and potential bypass operation at this location. Information created and provided under this Work Order is intended as a guide for use in performing the design and construction of the new master pump station. Compensation Atkins proposes to perform the work described in Tasks 1— 6 on a Fixed Fee basis with budgets between the sub -tasks and expenses being interchangeable as needed.
