There are two types of seal treatments, slurry seal and cape seal.

The application of a slurry seal will require lane/street closures between 8:00 a.m. and 5:00 p.m. On the day of slurry seal work, it is very important that you do not park your vehicle on the affected street or it will be towed in order for the contractor to perform his work. Equally important is that you be advised not to drive on, into or from closed lanes or on a street with the street closure barricades in place. Barricades are an indication that the slurry seal is wet and must not be driven upon or walked upon. Driving on the wet slurry would result in significant damages to the street. Moreover, driving on a closed lane or street is a violation of the City’s Municipal Code Sections 10.44.030 and 10.44.070, as is driving around barricades or moving barricades to gain access into or out a closed lane or street. Residents found to be in violation of the City’s Municipal Codes may be cited and found responsible for the cost to repair the damages resulting from the violation. Driving or walking on the wet slurry seal will damage the street and will cause the black tar-like substance to adhere to your car tires and shoes and track on driveways and sidewalks. Residents are advised to relocate their vehicles outside the work area in advance if they wish to have access their vehicles on the day of the street closure. The City will suspend street sweeping parking restrictions on streets adjacent to those being closed for work.

The application of a cape seal is a two step process. First, a heavy oil mixture and small gravel chips are applied (a chip seal). Residents are prohibited from parking on the street on the day of the application of the chip seal until the City’s contractor removes the “No Parking” barricades. Please be advised to stay off the street while work is in progress. After the contractor completes work on the chip seal and removes his construction barricades, residents will be permitted to drive on the street. For about one week, the chip seal will be exposed to allow setting. Please drive slowly over the chip seal as it is natural for some of the small gravel chips to come loose. About one week after the chip seal has been placed, a slurry seal will be applied on top of the chip seal to provide a new, smoother, driving surface. The same parking, driving and walking restrictions on a street being slurry sealed noted earlier in this notice applies to residents whose streets are being cape sealed.

The contractor will place door hangers or paper notification concurrently with no parking restriction signs on barricades. Please move your vehicle outside of the barricaded road closure area in advance of the work should you wish to have access to your vehicle during work hours.

If there are unique or extenuating circumstances that require access to be provided, please advise us in advance by calling a member of the Engineering Division at (650) 991 8064. Any questions can also be directed to this number.
