Novato Blvd: 3-Lane Project

Project Overview

Novato Boulevard Improvements - Diablo to Grant (CIP 01-004)


On June 12, 2018, Novato City Council approved a new 3-lane layout for the Novato Blvd. Improvements Project (CIP #01-004) between Diablo Ave. and Grant Ave.  The conceptual design includes sidewalk and bicycle lanes in both directions, utility undergrounding, new traffic signals at Diablo Ave, Seventh St., and Grant Ave. among other improvements.  The smaller project “footprint” should impacts to private properties, trees and creeks, but still improves traffic flow through the corridor during peak commute hours.  The preliminary project cost is estimated between $10M-$15M with approximately $12M of Marin County Transportation Sales Tax Measure A funding programmed for construction in the year 2021.

Because the project description has changed from the five-lane layout to the preferred three-lane layout, the City has filed a new “Notice of Preparation” of Environmental Impact Report under the California Environmental Quality Act. As a part of this process, the city requests that the public comment on the scope and content of the environmental information to be included in the project Environmental Impact Report. The public comment period closes on September 21, 2018 at 5:00pm. Comments should be sent to or by mail to: City Engineer, City of Novato, 922 Machin Ave., Novato, CA 94945.

Improvements are needed to enable the roadway and intersections to operate more efficiently and to enhance safety and usability for motorists, cyclists, and pedestrians. 


Construction is estimated to begin mid 2021and could take 12-24 months to complete the work pending final determination of the scope of work to be performed.


The preliminary construction and right-of-way capital cost estimates range from $10-15 million for the three-lane project. There is approximately $12.5 million programmed for project capital expenditures. 

Project Updates:

6/12/18:  City Council selected the three-lane layout as the preferred alternative and authorized staff to file a "Notice of Preparation" of Environmental Impact Report under the California Environmental Quality Act. City Council Presentation (June 12, 2018)

6/5/18: An update on the Novato Blvd Improvements Project will be given at the City Council meeting on Tuesday, June 12 at 6:00pm in the Council Chambers at City Hall. Staff will be recommending that a new three-lane layout be selected as the preferred alternative for this project instead of the current five-lane layout. The three-lane layout includes one through-lane in each direction and a continuous center turn lane. The three-lane alternative would likely reduce costs and environmental impacts.

Recommended 3-Lane Layout
 Removes approximately 28 mature trees
 Narrower “footprint” avoids Novato Creek
 Acquires land from approximately 6 properties    
 No houses are demolished
 Preliminary cost estimate: $10-15M

Several public workshops and meetings regarding this project have been held over the past ten years. The three-lane layout was presented at the most recent public workshops in April 2018 and the overwhelming majority of workshop participants preferred the three-lane alternative.

Residents’ concerns regarding proposed turning restrictions at Los Alondras Court have been addressed in the recommended three-lane alternative.  No restrictions are proposed for any side streets connecting to Novato Blvd.
