FAQs: Slurry Seal Asphalt Resurfacing Project

What is a microsurfacing “slurry seal"?

Slurry Seals are a mixture of oil, sand and admixtures that hardens to provide a protective layer to roadways. This is a preventative maintenance treatment used for upgrading “fair” or “at risk” roads to a “very good” condition with minimal costs when compared to more substantial pavement rehabilitations and reconstructions. This strategy is well documented as an essential component to any successful pavement management program and each road has been selected based on the current Pavement Condition Index (PCI), proximity to other planned work, daily traffic volumes, and other factors such as needed bicycle, pedestrian, and underground improvements.

What Corte Madera streets will be resurfaced? 

The map of roads below (click on the map to enlarge it) shows the streets in Town that will receive a "slurry seal". Starting the week of October 26, 2020, the streets listed in the chart are going to get a “slurry seal”. This webpage and the list from the chart will be updated once we receive confirmed dates and details.

Slurry Seal Schedule

How many days will the Contractor be on my street?

The project will occur on various streets in Corte Madera for an approximate 3 weeks duration. Resurfacing of each street will take place over an approximate two day time period. Other related construction activity may occur in the area for up to a few weeks before and after with only minor traffic inconveniences. 

Will I be able to access my driveway?

On the days of the “slurry” application, residents will not be able to drive on, or cross over the “slurry” seal oil into your driveway while the slurry is curing. Driving on the newly applied, uncured slurry surface could cause unsightly oil blemishes on your car or driveway.

 Where can I park on the days when work has been scheduled?

On scheduled slurry application days, the Town recommends residents park their vehicles down the street from the working area during the hours of 8am-5pm.  Residents will be required to move their cars prior to 8am if it is parked on the targeted street for application, or, if use of the car is anticipated during the 8am-5pm scheduled limited access window.  

On some of our residential streets with widths greater than 20 feet, slurry seal application will likely occur on two successive days, one side at a time.  This will allow residents an opportunity park their vehicles on the side of street that remains open, while the other side receives slurry.  Note, several adjacent streets may receive slurry at the same time and therefore some planning will be required.

How will I be notified of the schedule?

Prior to commencement of the project, Corte Madera residents will be notified in several ways.  In the next few days, residents will receive a letter in the US mail with information about the project. As we approach the start date of the slurry project, changeable message boards will be erected near the entrance to your neighborhoods. Additionally, Town Staff and/or its contractor will be providing a written notification of the intended start date of your neighborhood at your front door, 72 hour in advance of your street’s start date.
