San_Lorenzo_River_Channel_Improvement_Project_-_As-Built_Plans.pdf

This document is a set of as-built plans for the San Lorenzo River Channel Improvement Project prepared for the City of Santa Cruz Department of Public Works. The plans comprise 83 sheets detailing the completed construction and design specifications for the project, including critical infrastructure components such as pipe diameter specifications and pump station details. The as-built documentation serves as the technical foundation and reference baseline for related future improvements, specifically the rehabilitation of Pump Station No. 1 and construction of the new Soquel Pump Station that are the subject of the current design services procurement. These plans establish the existing conditions and completed work against which subsequent design phases and construction activities will be coordinated and integrated. The document includes comprehensive sheet-by-sheet details spanning hydraulic systems, structural components, and site-specific configurations necessary for understanding the channel improvement work that has been executed to date.

The as-built plans function as a critical deliverable and reference document for the City's stormwater management infrastructure improvement initiatives. These technical drawings and specifications are maintained by the City of Santa Cruz and are incorporated by reference into the current design procurement to ensure that consulting teams responding to the Pump Station 1 and Soquel Pump Station design solicitation have access to accurate existing conditions documentation. The plans were developed as part of the broader San Lorenzo River Channel Improvement Project and establish the engineering baseline upon which the $1.8 million design services contract for pump station improvements will build. Firms selected for the design services contract must review and integrate these as-built plans into their hydraulic modeling, basis of design development, and 50%, 90%, and 100% design phase deliverables to ensure consistency and compatibility with completed infrastructure improvements and compliance with project objectives for flood protection during 5-year and 25-year storm events.
