SUBJECT:
2026 Sanitary Sewer Root Foaming (North Basin) — Agreement RECOMMENDATION:
Award an agreement to Duke’s Root Control, Inc. for the 2026 Sanitary Sewer Root Foaming (North Basin) project in an amount not to exceed $415,950.13; establish a contingency reserve of $40,000.00; and authorize the Public Works Director to execute the agreement in substantially the form presented and issue change orders within the contingency amount.
BACKGROUND:
The City of San Mateo treats parts of its sanitary sewer system with a foam herbicide to control root intrusion as part of the Public Works Department’s Sewer System Management Plan. Root control is one of the methods the City uses to reduce sanitary sewer overflows caused by root blockage, required as part of the 2009 Cease and Desist Order issued by the Regional Water Quality Control Board. The project area limits are west of El Camino Real, north of State Route 92, and south of the border with the Town of Hillsborough. This project will treat approximately 199,000 linear feet of sanitary sewer pipe sizes 4” through 30”.
The City advertised this project on June 4, 2026, and bids were opened on July 2, 2026. One (1) bid was received, shown in the table below. The engineer’s estimate is $410,000.00.
Company Name Total Bid Amount
Duke’s Root Control, Inc. $415,950.13
After a review of the bid documents submitted by Duke’s Root Control, Inc., staff determined that the bid is responsive and the bidder is responsible, and therefore recommend awarding the agreement to Duke’s Root Control, Inc.
BUDGET IMPACT:
Sufficient funds are available in the Root Foaming Project (469933) for this agreement and the requested contingency reserve.
ENVIRONMENTAL DETERMINATION:
This project is categorically exempt from CEQA as an “existing facility,” because it consists of the operation, repair, maintenance, permitting, leasing, licensing, or minor alteration of existing public or private structures, facilities, mechanical equipment, or topographical features, involving negligible or no expansion of existing or former use. (CEQA Guidelines Section 15301.)
