About this file
This is a project design and maintenance specification document from the City of Santa Cruz Public Works Department for the Pogonip Creek Culvert and Channel Cleaning 2026 project. The work consists of the removal and disposal of sediment from two culverts (N9-UI303-N9-UO302 and N9-UI304-N9-UO305) and clearing excess sediment buildup from the open channel that connects these culverts to maintain steady water flow. The primary maintenance tasks include clearing a 48-inch diameter pipe approximately 36 feet in length that is partially filled with sediment, clearing a 12-inch diameter pipe approximately 20 feet in length, dredging approximately 60 feet of channel from the upstream culvert to the downstream inlet, and removing and replacing access gates and fencing as necessary. The project location is situated near the San Lorenzo River in the Pogonip area of Santa Cruz, California, within proximity to the Monterey Bay, De Laveaga Park, and UCSC. The project was designed on April 13, 2026, and spans three sheets of technical drawings including a title page, maintenance plan, and detailed specifications. The City Engineer has approved the project, and all contractor communication regarding the work must be coordinated with the City Inspector with 24 hours advance notice prior to cleaning operations.
The Engineer's Estimate for this project is $30,000. Contractors must possess a current Class A license at the time of contract award and obtain a City of Santa Cruz business license prior to commencing work. The specifications note that underground utility main lines for gas, water, storm drain, and communication are shown for general information only, and contractors are responsible for field verification of all utility locations and depths. The sediment in the culverts was assessed as of March 25, 2026, and documented as soft and spongy in composition. While no specific bid submission deadline, site visit requirements, or bidder's conference information is contained within these technical plans, they serve as the design basis for contractor scope of work execution and quality standards.
