Notes on Cost Estimation:
(2) Estimated Construction Cost includes a 30% contingency of the baseline construction cost.(3) Total project costs includes a 10% markup for engineering, a 10% markup for construction management and a 7.5% markup for project administration of the estimated construction cost.

Project Cost Allocation: Project Detail:Reimbursement Category Existing Users
Future UsersTotalProject will address existing capacity deficiencies, therefore 0-percent of cost is assigned to future users.
(4) The CIP costs for this project are considered atypical due to bypass pumping requirements and challenging crossings, and were estimated saprately from the master plan unit costs. (1) ENR 20 City Average Construction Cost Index for March 2025 is 13,782.

This project will replace approximately 3,600 feet of 18-inch diameter pipeline in North Ranch Street and through the Visalia Country Club with a new 24-inch sewer, extending from West Mineral King Avenue to West Goshen Avenue. This project is needed to mitigate existing capacity deficiencies associated with historical peak discharge rates associated with the milk processing plant upstream of this sewer main.Project Details:Project Element Existing

This project will replace approximately 7,500 feet of 36-inch diameter pipeline in American Street, extending from Ferguson Avenue to Camp Drive. Under ultimate peak flow conditions the 36-inch pipeline surcharges and exceeds the maximum d/D criteria. To mitigate the capacity deficiency, it is recommended that the existing pipeline be replaced with a 42-inch diameter pipeline. Project Details:Project Element Existing

This project will replace approximately 6,200 feet of 36-inch diameter pipeline along an unimproved area and in Frontage Road. The existing pipeline parallels Highway 99 and is west of the Airport. The project extends from downstream of the Airport Lift Station to Walnut Avenue. Under ultimate peak flow conditions the 36-inch pipeline surcharges and exceeds the maximum d/D criteria.

This project includes the installation of a 24-inch diameter pipeline extending from the Walnut LoversLane Trunk to the Walnut Outfall Trunk. The overflow is recommended to alleviate surcharging within the 42-inch pipeline crossing Highway 99 and minimize the backwater effect occurring upstream. The Walnut Outfall Trunk has capacity to allow for overflow from the parallel trunk. Project Details:Project Element Existing

Lift Station
Notes:(1) ENR 20 City Average Construction Cost Index for March 2025 is 13,782.

The firm capacity of this lift station is not adequate to convey Ultimate Buildout flows. The City’s Airport Lift Station will need to be replaced in the future to accommodate growth in the planning area. This lift station provides service to Sewer Drainage Basin 7, which includes the Industrial Park. In addition, the Census Designated Place (CDP) Goshen discharges upstream of the lift station. This project is considered long term and would be required beyond buildout of the UGB. It is recommended to increase the firm capacity to 17.0 mgd. For planning a total capacity of 25.5 mgd with 3 pumps is assumed.Project Details:Project Element Existing

This project provides a preliminary alignment to extend sanitary sewer service to residents currently on septic and located in the City limits or county islands. Projects WW0-1 through WW0-12 were identified due to their proximity to existing sewer line. Project WWO-1 consists of 2,600 feet of 8-inch diameter pipeline in Linwood Road, Oakridge Court, and Kent Street. The project extends to the intersection of W Ferguson Avenue. This is a County Island project which is only likely to occur as a condition of Annexation.Project Details:Project Element Existing

This project consists of 2,600 feet of 8-inch diameter pipeline in Sol Road. Based on preliminary data, the pipeline would not maintain a minimum recommended slope. Therefore a lift station is recommended.

A preliminary analysis shows to maintain a minimum slope upstream a lift station is required. This project would serve existing users transitioning from septic to the collection system. The lift station is recommended to have a firm capacity of 0.02 mgd (15.7 gpm) and would provide service to residential very low density.
