June 1985 to October 1985

Developer: Pacific Island Development, Newport Beach, California

 

PROJECT: RIVER RUN, CORONA, CALIFORNIA.

 (APPROXIMATELY 100 ACRES IN A HISTORIC RIVERBED DEVELOPED FOR THE CONSTRUCTION OF SINGLE AND MULTI-FAMILY HOMES.)

I managed the grading and placement of settlement monitors in low areas of the project while constructing a temporary channel to confine flood flows.  Street improvements required for the future development were an integral part of this project.

 

The most prominent example of my ability to resolve complex issues with simple cost efficient solutions on this project is displayed in the construction of a lining for the temporary flood control channel.  The project engineer and soils consultant had specified 2% soil cement as walls for the temporary channel.  This method was specified due to the expectation that the channel would be in service for at least two years while the building pads settled to allow construction of the permanent channel.  The cost of the soil cement lining was estimated at $360,000. I designed and installed a temporary channel lining utilizing two geofabrics that protected the walls of the channel and could be easily removed later. We built the alternate lining that provided excellent service for the next four years for $60,000
