2013-14 Pavement Rehabilitation Project (Area A & B)

OE provided design engineering services to the City of La Mirada for the city's first residential rehabilitation project utilizing local Measure I funds. Measure I is a local funding measure for La Mirada's infrastructure maintenance. The project area was exclusively residential with parks, schools, pedestrian walkways and equestrian trails. The project encompassed localized street reconstructions, street resurfacing, slurry seal, storm drain lining of the existing corrugated metal storm drain, and concrete repairs of curb, gutter and sidewalks with ADA access ramps; adjustment of manholes and valve cans and new striping and traffic loop detector replacement. In addition, the existing slotted cross gutters required replacement to current roadway standards. OE completed the field investigations and necessary topographic surveys to provide a cost effective design solution that maximized construction dollars through the use of thin lift ac overlay, spot roadway reconstruction prior to overlay and slurry seal, and limited roadway reconstruction. OE videotaped all the existing corrugated metal storm drains within the project area, and the video confirmed that the metal pipe contained debris and the flow line was rusted and needed repairing. Furthermore, the project required OE to meet with City staff to determine that in-situ form in-place lining is the most cost effective method to rehabilitate the storm drain pipes.
