Area G (Portola Hills) Week of April 26, 2021

The contractor will be doing asphalt repairs at the intersection of Trabuco and Bake Parkway on Saturday April 24, 2021.

The City of Lake Forest is actively slurry sealing Zones C and G, to ensure a safe, smooth roadway surface and make certain the roadways last as long as possible. The schedule allows for on-street parking within approximately 1,000 feet from any home impacted by that day's work. Slurry sealing will occur during the week.  The work is scheduled to not impact trash-pick up days, if trash pickup day cannot be avoided the residents will be notified in advance, but it is not anticipated at this time.

This project will be completed in four general phases: 

  1. First, a pavement repair crew will complete spot repairs of the areas that have the greatest deterioration. These areas have already been identified by the City.  “No Parking” signs will be placed 48 to 72 hours prior to the work.  Residents will have access to the streets and driveways during this process.  Access may be limited for 30 minutes as the contractor grinds out the deteriorated areas and repairs the pavement.
  2. Second, a crew will be in the streets crack sealing. This activity will place sealant in cracks that meet specific criteria, not necessarily every crack. 
  3. Third, a crew will place slurry over the entire streets. The streets will be closed from 7:00 am to 5:00 pm or as the signage states.  This is intended for a single work-day closure, while the entire street is slurry sealed.  The contractor, will notify residents via door hangers seven days prior to work, and again 24 hours prior.
  4. Fourth, a crew will restripe pavement markings. 

Throughout the process there will be various parking restriction and traffic control signs, please adhere to all posted signage. Trash will be picked up on the normal pickup schedule. The contractor, will notify residents prior to the slurry work that requires a single day street closure via door hangers seven days prior to work, and again 24 hours prior.

The City maintains approximately 200 miles of roadway. Slurry seal provides a protective coating to reduce wear and prevent water from seeping into the roadway, which can cause potholes.   The City's goal is to provide good, quality roads for our residents. This will require the City to interrupt residents’ normal routines, while the project is under construction. The City is working to get residents back to their normal routines as quickly as possible. Thank you for your patience while the City improves your streets.
