City of San Jacinto 7th Street Pavement Repairs Joe Mouawad, P.E. September 7, 2016

7th Street Pavement Repairs Uneven pavement and surface damage are visible along 7th Street between Sanderson Ave. and Ivy Crest Drive in City of San Jacinto Pavement condition is associated with District’s sewer project completed in 2008 District made repairs at select locations in 2010 and 2015 Additional repairs necessary

Evaluation of Pavement Conditions Areas repaired by the District Distressed pavement areas No curb/gutter District retained Inland Foundation Engineering (IFE), the soil engineer on the sewer project, to evaluate the sewer backfill and to develop a solution IFE conducted additional field investigation (CPT test) at five locations along the sewer alignment to study the subsurface soil conditions

Soil Investigation Findings Backfill material was compacted to 90% level or higher during construction However, potential settlement in the pipe zone may have weakened the backfill zone above the pipe Continued settlement in the backfill zone is likely resulting in pavement distress Poor surface drainage and storm water infiltration increases settlement potential

Recommended Repair Solution Improved Pavement Section: Bottom soil layer compacted to 90% level Three layers of aggregate base/geogrid 4-inch Asphalt concrete City of San Jacinto and the District identified 900-feet of roadway to be repaired District will continue to monitor the pavement for surface depressions Repair Areas Note: Remaining distressed pavement areas will be monitored
