San Dimas Avenue from Foothill Boulevard to Gladstone Street
Upon completion of the street improvements on San Dimas Avenue from Foothill Boulevard to Gladstone Street, the City immediately raised a concern with the contractor regarding the smoothness and ride quality of the final asphalt pavement layer. Although it was not visible to the naked eye, the City suspected the finished paving surface did not meet the requirements of the project specifications. After extensive examination and test of the street, the City confirmed that portions of the finished paving surface were not in compliance. Even though the undulations of the substandard finish do not have any long-term detrimental effect on the design life of the street, the City requested the contractor to address and resolve this matter.
The contractor started the repair work on July 27, 2010, and the work should be completed within one (1) week. The repairs will be done by the contractor at no additional cost to the City of San Dimas.
In order to expedite the work and for public safety, there will be restricted access and limited use of San Dimas Avenue during the final phase of the repairs. Please understand that to ensure a quality finished product, sufficient time must be provided for the seal coat material to set prior to allowing any traffic over it. Due to equipment delays and scheduling conflicts, the contractor has rescheduled to seal coat the street on Monday, August 9, 2010 and Tuesday, August 10, 2010. (Please note that this scheduled work may change due to weather or delays.)
On Monday, August 9, 2010, please note that the contractor will be closing the northbound and southbound #2 lanes (outside lanes) from approximately 8:00 am to 3:00 pm. During that closure time, no vehicle will be allowed access onto or off of any street or driveway adjacent to San Dimas Avenue. Please plan accordingly.
On Tuesday, August 10, 2010, please note that the contractor will be closing the northbound and southbound #1 lanes (inside/median lanes) from approximately 8:00 am to 3:00 pm. During that closure time, no vehicle will be allowed to make any left-turn movements onto or off of San Dimas Avenue.
The City of San Dimas regrets any inconvenience this repair work may cause. Every attempt will be made to expedite the project so as to minimize the impact on residents and business owners. Your cooperation and attention to temporary traffic control signs, markings and observing posted speeds will greatly assist in helping the Public Works Department to expedite the completion of this project and allow a faster return to normal traffic patterns.
