On-Call Capital Improvement Projects and Engineering Services

EKI has assisted Coastside County Water District (District) in managing and implementing its 10-year Capital Improvement Project (CIP) since November 2018. EKI has helped the District prioritize, program, manage, plan, design and oversee the construction of its near-term capital improvement projects. Specifically, EKI has completed the following projects:

• CIP Management: Our engineering experts conducted a detailed review of the District’s 10-year CIP budget and prepared implementation schedules for 2-years and 10-years along with cash flow analyses for both terms.
• Project Management: We provided project management services that included preparation of request for proposals, selection and management of consultants, and review of work project deliverables for projects. An example is the seismic evaluation of the District’s welded-steel water storage tanks.
• Water Distribution System Design and Construction Management: Our engineers have designed and managed 29,000 LF of new water mains for the District, ranging in size from 2-in to 20-in. Several projects have included trenchless construction, including several horizontal directional drilling (HDD) installations under creeks with sensitive habitats and bore and jack across Highway 1. Projects have also included the installation of new pressure-regulating valve (PRV) stations. In addition to the design, bid support and construction management, EKI has been responsible for easement support, environmental compliance, permitting and construction inspection for several projects. EKI is currently designing a pipeline rehabilitation using a flexible reinforced fabric liner (Primus Line).
• Storm Drainage and Road Resurfacing Design and Construction Management: EKI completed design and construction management for the replacement of the existing culverts and reconstruction of the steep access road from the Denniston Water Treatment Plant to the Denniston Tank Site.
• Development Projects and Third-Party Review: EKI has reviewed development applications for new service and mainline extensions to evaluate services and ensure compliance with District standards. The projects were specifically for New RV and City parks. Additionally, EKI reviewed and proposed updates on the District’s Non-Complex Mainline Extension Policy, Half Moon Bay Highway 1 North Improvements and San Mateo Midcoast Multi-Modal Trail Improvements.
• Hydraulic Modeling: EKI has updated the District’s water system hydraulic model to incorporate recent system improvements, current demand conditions and recent pump curves and settings. Our engineers also performed an extended period of simulation calibration.
• Systemwide Storage Evaluation: EKI prepared a systemwide storage evaluation to assess the District’s existing storage tanks and prioritize future storage improvement projects in the District.

Outcome

Recently, EKI has expanded its role with the District to review development applications for new water services and mainline extensions.
