Time:                     10:00 AM

Location:     REMOTE MEETING VIA VIDEOCONFERENCE

Mission Rock Project (3rd Street and Mission Rock Street;

Final  Map PID 9443, Request For Amendment to LCC Design Criteria

Subdivider of the Mission Rock Project (3rd Street and Mission Rock Street; Final Map PID 9443) (“Project”) submitted a request to amend the Lightweight Cellular Concrete (LCC) Design Criteria previously approved through Director Order 203636. Order 203636 specified two different cast densities for LCC, ranging from 28 to 32 pounds per cubic foot (pcf) for the upper 2 feet of LCC, and 25 to 29 pcf for the remainder of LCC. The primary reason for the higher cast density in the upper 2 feet was to provide a higher compressive strength. Based on available data from LCC installed to date through this project, it has been demonstrated that LCC with a cast density between 25 and 29 pcf can achieve the compressive strength within the specified range of 80 and 200 psi, and is therefore recommended by the Subdivider’s geotechnical engineer for use in the upper 2 feet of LCC. Subdivider requests amendment to Order 203636 to establish one cast density ranging from 25 to 29 pcf for the entire LCC section that will apply to Mission Rock Phase 1 Street

Improvement Permit #20IE-00486. Included with this request is a request to reduce the 10- day Public Noticing requirement to 5 days.
