SJCDPW-RFQ-25-04
The San Joaquin County Department of Public Works (SJCDPW) requests Statement of Qualifications (SOQ’s) from qualified and innovative Consultants to provide consulting engineering services for the full engineering design services for the Acampo Innovation Project (Project). The selected Consultant (Consultant) will be requested to enter into a Consultant Services Agreement with the San Joaquin County as set forth in this Request for Qualifications (RFQ).The Consultant shall be required to provide all labor, equipment, tools, and facilities necessary for the completion of the Project. The Cooper’s Corner area of San Joaquin County, near the unincorporated community of Acampo, experiences periodic flooding about once every 10 years on average due to changes in the upper watershed that occurred over generations. In response to flooding in 2017, a multiphase plan was developed entitled “Acampo Area Drainage Innovation Plan”. The first phase of the plan was completed in 2019 and consisted of a drainage system that intercepted drainage flowing into and from within the Cooper’s Corner community. The system was intended to reduce the frequency, severity, and duration of recurring shallow flooding within the community. Unfortunately, the area was again subject to significant inundation in 2023. The second phase of the plan will further flood risk reduction efforts by intercepting surface run-off upstream of this area and diverting it south towards the Mokelumne River and diverting a portion of the flows onto agricultural lands with suitable soil profiles. In addition to reducing flood risk for the Cooper’s Corner, the redirected run-off would improve groundwater conditions in the critically over-drafted Eastern San Joaquin groundwater subbasin. The Project consists of development of 100% engineering plans, specifications, environmental documents and engineers estimate of probable construction costs for drainage and water retention and recharge improvements to reduce the risk of severe flooding in the areas at east of California Highway 99 (SR 99) at Woodbridge Road, Acampo Road, and Peltier Roads which have experienced flooding and resulted in the temporary closure of SR 99 and the evacuation residents in the Cooper’s Corner area.
