Public Works FAQ

Who can I call or email about questions I have?

Which construction projects are allowed to be active?

The County of San Mateo has issued a revised health order that allows for all construction activities to proceed with safety protocols identified for Small Construction Project Safety Protocol and Large Construction Project Safety Protocol construction projects. 

Do I still have to move my car if ‘no parking’ signs have been placed on my street?

Yes please. We place ’no parking’ signs 72-hour before construction begins in a work zone. Note the date construction starts on the ‘no parking’ sign and please be sure to move your car by that date.

Can I get an encroachment permit?

Unable to submit applications electronically? Please contact Judy for assistance. We highly encourage online applications. Appointments for permit submittal are limited and may take more time to process.

Can I go to City Hall to apply for a permit?

At this time, we are asking that people utilize online application process as it is more efficient and safer for all. In some situations, appointments will be available, but very limited due to social distancing requirements for staff and visitors. 

How will I know if a construction project is in my neighborhood?

For all projects from Public Works, residents receive postcard notification. Some larger projects are posted to our social media channels. Be sure to follow us on our social media for current updates and news. 

Another option is to visit the project pages of 25th Grade Separation Project and Clean Water Program where you can register for email updates. Once registered, you will receive notifications of upcoming work on those projects. 

When did street sweeping return?

On Monday, June 15, 2020, the City returned to its normal residential street cleaning schedule. Downtown and commercial street cleaning schedules were not interrupted during the COVID-19 Shelter-In-Place orders. Parking enforcement along street cleaning routes begins again on July 15, 2020. 

If you are registered for residential street cleaning email alerts, you will begin to get regular email alerts in advance of your scheduled street cleaning. We had paused the email alerts during the health orders. 

Why is caution tape on some walk signal buttons? Crosswalks - No-touch Intersection

In May, as an extension of the Safe Streets San Mateo initiative (see below), we eliminated the need for pedestrians to press the push button at 28 intersections around town. Less people touching the button means less spread of the COVID-19 virus in our community. This is in addition to the 24 locations in downtown San Mateo with this same feature. 

When you see caution tape across the ‘walk’ buttons there is no need to push the button to get the walk signal. When the light goes green, the walk symbol will automatically light up, allowing pedestrians to cross the intersection safely.

Drivers may experience longer wait times at these intersections due to the extended walk symbol. We thank our neighbors for their continued patience and cooperation in helping everyone do their part to slow the spread of COVID-19 in our community.

What is the Safe Streets San Mateo initiative? Safe Streets - A-Frames - Neighborhoods

In early April, we implemented precautions to help our neighbors recreate safely outdoors by launching the Safe Streets San Mateo educational campaign across our social media channels. The campaign reminded all to share the road when outside during the COVID-19 health orders. The initiative intends to remind our residents to use our roads and bike paths safely during the ongoing shelter-in-place orders.

In addition, staff consulted with neighborhood leadership in areas identified to benefit from a Safe Streets road segment and implemented traffic calming signage in Bay Meadows, North Central and Central neighborhoods by mid-May. 

In advance of the Memorial Day weekend, staff implemented safety signs on the Bay Trail within the city limits to remind those recreating to slow down, keep 6’ of distance from strangers, and wear masks when near others.
