Document Description
Project Description: The Project will replace approximately 5,200 linear feet of potable 16-inch water mains and install new fire hydrants every 300 feet along Sand Hill Road and Monte Rosa Drive. Abandonment in place of approximately 3,000 linear feet of an existing 16-inch diameter potable water main within a landscape buffer north and east of Sand Hill Road is also proposed. No upsizing is proposed. Staging will occur on various portions of existing streets during construction. Construction activities will include trenching, pipeline construction, repaving, and returning surfaces to pre-project conditions or better.
Beneficiaries: MPMW purchases all its water from San Francisco Public Utilities Commission (SFPUC) and is fully reliant on that supply to meet the needs of businesses and approximately 19,000 residents through 4,400 water connections. MPMW provides water to two service areas. The upper zone, located in the Sharon Heights area and the lower zone, located east of El Camino Real/State Route (SR) 82. The proposed Project is located within MPMW’s upper zone and will serve residential, commercial, and recreational area within Sharon Heights (southwestern Menlo Park).
Purpose: Menlo Park Municipal Water has identified portions of their distribution system that require replacement. Initiatives within Menlo Park’s Capital Improvement Program (CIP) will upgrade aging water infrastructure to ensure public health protections and system reliability (Menlo Park 2019-2024 CIP). The Project will implement City of Menlo Park’s standards for potable water pipeline construction and abandonment. Project activities must also adhere to Caltrans standards. Project construction is anticipated to begin on June 1, 2026 and conclude on February 1, 2027; resulting in approximately 100 feet of pipeline installed daily.

Notice of Exemption
Exempt Status
Categorical Exemption
Type, Section or Code
Existing Facilities - Class I Categorical Exemption, CEQA Guidelines, Cal. Code Regs. tit. 14 § 15301 (b) and (f)
Reasons for Exemption
The Project will replace and modify a portion of an existing potable water system that has reached the end of its useful life. Relocation of the water main will increase efficiency of ongoing maintenance due to accessibility within the street. Additional fire hydrants will enhance accessibility for fire response. The Project is a component of an existing publicly owned water utility and will not expand service to additional customers. The Project is an approved Capital Improvement Project consisting of minor alteration and maintenance of an existing utility for public safety and welfare; it will be implemented by Menlo Park Municipal Water for continuous water delivery and appropriate fire response within the existing service area.
