Baden Avenue is reduced to two-lanes to allow travel in the eastbound and westbound directions during this nighttime construction. Adjacent businesses will remain open and access will be maintained as work is underway.

About the Project:
This project includes two seven-story residential buildings with 260 units located at the corner of Miller Avenue and Airport Boulevard. It is anticipated to be complete by Q2 of 2019. The project is considered transit-oriented development because of its proximity to the Caltrain Station, numerous bus stops, retail and restaurants located nearby on Grand Avenue. (Rendering below)

The contractor completed demolition of the former buildings and grading to make the site slope more accommodating to new development. To accomplish this, the developer performed extensive importing and exporting of materials and soil at the site. The Developer recently submitted plans to secure a building permit. Once the City has reviewed and approved the building permit vertical construction will begin.
Alert: The contractor is importing soil to the site on a 24/7 timeline through Monday, February 18. Work will impact Oyster Point Boulevard between the Oyster Point Boulevard US-101 off-ramp and Marina Boulevard due to trucking.

Phase I of construction at the US-101 northbound off-ramp and Poletti Way continues which includes the demolition of the sidewalk and adjacent landscaping at Poletti Way north of East Grand Avenue.

A temporary lane and sidewalk closure along Poletti Way between East Grand Avenue and Corporate Drive continues in order to facilitate street improvements as part of the Caltrain South San Francisco Station Improvement Project. One lane of Poletti Way is accessible to local and through-traffic during construction.
Waterline installation along Grand Avenue and Poletti Way continues through Wednesday, February 13.

About the Project:
A key component of the Caltrain Modernization Program is the electrification of the Caltrain Corridor from San Francisco’s 4th Street and King Street Station to the Tamien Station in San Jose. The project will replace the diesel-hauled trains with Electric Multiple Unit trains. This will improve Caltrain system performance, enable more frequent and/or faster train service, and reduce long- term environmental impacts by reducing noise, improving regional air quality and reducing greenhouse gas emissions. Caltrain electrification is scheduled to be operational by 2022.
Please visit the Caltrain website to sign-up for weekly construction updates. If you have questions or comments about the upcoming work, please call the Caltrain dedicated Project Hotline at 650.399.9659.

Roadway improvements continue along El Camino Real. Work is divided into two sections along El Camino Real:
1. El Camino Real at McLellan Drive to 300 feet south of Kaiser Way (north location)
2. El Camino Real at Chestnut/Westborough Avenue intersection to 250 feet north of Arroyo Drive (south location).
Between Monday, February 11 and Friday, February 15, construction will continue with intermittent lane closures along El Camino Real. These intermittent lane closures are subject to Caltrans approval. If approved by Caltrans, lane closures will affect the southbound lanes of El Camino Real beginning at McClellan Drive through Kaiser Way and speed limits will be reduced to 30 mph in the construction zone.
Access to SamTrans bus route service and Kaiser Permanente via El Camino will be maintained. All businesses will remain open and every effort will be made to keep a minimum of two lanes open in each direction of travel.

With all the new residential buildings which will add many more people to the city, I see NO traffic flow improvements or wider roadways and streets. How is the city going to respond to the added traffic and parking problems other than adding a few white lines and a couple of signals?
