Phase 2 Mitigation Measures
As a result of the historical operations, soil and groundwater in the northern and northwest areas of the
Uptown Newport project site are impacted by VOCs from historical releases of chlorinated solvents from
underground storage tanks (USTs). Solvents were detected in soil at the site in January 1984 during an
investigation of a broken water line northwest of the TowerJazz building. The suspected source was two
former solvent tanks located northwest of the TowerJazz building. This area has been the primary focus of
historical and ongoing soil and groundwater investigation and remediation activities conducted under the
oversight of the RWQCB. These remediation activities have resulted in reductions of chemical
concentrations at the site and adjacent properties.
The following redline revisions are proposed for the Uptown Newport MMRP to allow for development of
Phase 2 parcel-by-parcel, with the proposed soil remediation occurring independently of development
within Phase 2 that is not impacted by the soil or groundwater contamination.
The following are the proposed revisions to MM 7-7 through MM 7-11:
7-7 Prior to the issuance of building permits for any implementing development within Phase 2, the
project applicant shall obtain a “No Further Action” declaration or Letter of Allowance for
residential construction for the parcel being developed within Phase 2 from the Regional Water
Quality Control Board.
7-8 Prior to issuance of demolition permits, the project applicant shall have the following inspections
and assessments conducted for the Half Dome building (Phase 1) and TowerJazz building (Phase
2) and shall provide the Community Development Department with a copy of the report of each
investigation or assessment.
• The applicant shall retain a certified lead inspector/assessor to inspect buildings onsite for
lead-based paint (LBP). The inspector/assessor’s report shall describe regulatory requirements for
lead containment applicable to any LBP discovered onsite.
• The applicant shall retain a licensed or certified asbestos consultant to inspect buildings
onsite for asbestos-containing materials (ACM). The asbestos consultant’s report shall include
requirements for abatement, containment, and disposal of ACM in South Coast Air Quality
Management District Rule 1403.
7-9 Prior to the issuance of building permits for any implementing development within Phase 2, the
project applicant shall retain a registered environmental assessor or other professional qualified
to conduct a human health risk assessment (HHRA) for the parcel for development of potential
volatile organic compound contamination. The HHRA shall be conducted under the guidance and
review of the Regional Water Quality Control Board.
7-10 Prior to issuance of a building permits for any implementing development within a Phase 2 , the
project applicant shall demonstrate to the Community Development Department that
contamination in soil and groundwater on the parcel for development has been remediated to
meet the cleanup goal for the site for total volatile organic compounds set by the State Water
Resources Control Board and shall have obtained a “No Further Action” declaration or Letter of
Allowance for residential construction from the Regional Water Quality Control Board.
Deleted: Approval of tentative tract map(s) for Phase 2
shall not occur until the project applicant obtains a “No
Further Action” declaration or a Letter of Allowance for
residential construction from the Regional Water Quality
Control Board.…
Deleted: Phase 2 development
Deleted: Phase 2
PA2021-105
7-11 Prior to the issuance of demolition permits for Phase 2, the construction dates for the SCE
Substation shall be confirmed. If the facility was constructed prior to the 1980’s, a certified
inspector approved by the City of Newport Beach Fire Department shall be retained to test for
PCBs and related hazardous materials. If PCBs or other hazardous materials are determined to be
present, a mitigation program to abate, contain and dispose of the materials shall be prepared
and approved by the City Fire Department. Such program shall be implemented prior to the
issuance of Phase 2 building permits.
Condition of Approval No. 66 Revisions:
66. Prior to the issuance of building permits, the applicant shall demonstrate to the satisfaction of
the Director of Community Development that the Santa Ana Regional Water Quality Control
Board has issued a "No Further Action" (NFA) declaration or a Letter of Allowance for residential
construction for the portion of the site being developed.
Deleted: within each development phase of the project
