Commonwealth Building 3

162-164 Jefferson Drive

The Sobrato Organization proposes to construct a new 249,500 square-foot, four-story office building and a new approximately 404,000 square-foot four-story, five-level parking structure with 1,340 parking spaces, located at 162-164 Jefferson Drive. The site contains two existing four-story office buildings, each approximately 129,960 square feet in size, to remain on the project site. The total existing and proposed office development on the parcel would be approximately 509,420 square feet.

The proposed project includes a publicly accessible park along Jefferson Drive. The applicant is requesting modifications to the City’s bird friendly design standards and the use and storage of hazardous materials (diesel fuel) for an emergency backup generator. To comply with the City’s below market rate requirements for commercial projects, the applicant has proposed to pay the below market rate commercial linkage in-lieu fee.

As part of the ConnectMenlo General Plan and Zoning Ordinance update, the site was rezoned to O-B (Office, Bonus). The proposal includes a request for an increase in height and floor area ratio under the bonus level development allowance in exchange for community amenities. The required community amenity value is still being determined and once the appraisal for bonus level development is finalized it will be published to this project page. The applicant is proposing payment of a community amenities in-lieu fee.

Notice of preparation

A notice of preparation is an initial step to inform members of the public that an environmental impact report is going to be prepared.

The notice of preparation and the scope of the environmental impact report were the subject of the June 3, 2019, Planning Commission scoping session and study session. The following comment letters were received during the notice of preparation comment period:

Initial study

An initial study was prepared to evaluate the potential environmental impacts of the project and determine what level of additional environmental review is appropriate. Based on the initial study findings, a focused environmental impact report was prepared for topics that require further analysis: population and housing, transportation, air quality, greenhouse gas emissions, noise, cultural resources and tribal cultural resources, biological resources, and utilities and service systems.

As a result of the 2017 settlement agreement between the City of Menlo Park and the City of East Palo Alto, housing and transportation were required to be analyzed.
