Big Canyon Subdivision

Big Canyon Subdivision

The City of Newport Beach has completed a subsequent initial study and mitigated negative declaration for the Big Canyon Subdivision project. MND No. ND2010-006 was approved for General Plan Amendment No. GP2007-008. Planned Community Text Amendment No. PD2007-008, and Parcel Map No. NP2007-029 (PA2007-210) to allow the creation of a new single-family residential parcel at 10 Big Canyon. The applicant proposes additional grading to raise the existing grade on the project site by 10 feet to improve the integrity of the currently wet alluvial soils and create a pad for future development of a single-family residence on the subject property within the PC-8 (Big Canyon Planned Community) Zoning District). Approximately 12,000 cubic yards of soil will be removed and spread over a 1.8 acre area on the northern portion of the subject property and across the Big Canyon Golf Course (1850 Jamboree Road) adjacent to the subject property to the northwest. An additional 7,000 cubic yards of soil will be exported to a spoils site located at the east end of the golf course adjacent to MacArthur, Boulevard (1850 Jamboree Road). Following removal of soil from the project site, 45,000 cubic yards of soil will be imported from the Orange County Sanitation District (10844 Ellis Avenue, Fountain Valley, CA) to replace unusable soil with "clean" imported fill and will raise the pad for subsequent development of the project site. Project grading is expected to occur over a 60-day period beginning in March of 2012 included in the grading project is the enclosure of 175 s.f. (0.004 acre) of the existing relict drainage feature into a single, 48-inch corrugated metal pipe to redirect the drainage feature on the Big Canyon Golf Course.
