Project Name OC Sanitation District Pump Station Replacement
Address: 250 East Coast Highway
(PA2023-0076) Site Development Review, Coastal Development Permit, Limited Term Permit (TBD)
A request for the reconstruction of an existing OC Sanitation pump station located near the bay bridge
(Bay Bridge Pump Station), which includes the construction of a new pump station and force mains. The new pump station includes structures below grade, above grade electrical building, generator room, and a structure for odor control. Please see detailed plans and project description (included in the “Files”
section in Energov).
REPORT REQUESTED BY: April 28, 2023
PLANNING COMMISSION HEARING DATE: TBD Check all that apply:
No comments on the project as presented.
Notes:
The site is located in a Liquefaction Seismic Hazard Zone, for
purposes of Geotechnical and Structurural design of the building
the Project is assumed to be in Seismic Risk Category IV per Table
1604.5 of the 2022CBC. To reduce the Risk to Category III the
project engineer must prove that the building will not exceed the
maximum allowable quantities per control area as given in Table
307.1(2) of the 2022CBC. The Geotechnical Engineer must
determine Site Classification per ASCE7-16 Chapter 20, Table 20-
3-1 with supporting blow count or shear wave velocities. Soils
vulnerable to potential failure due to liquefaction, sensitive clays
and collapsible weakly cemented soils are required to perform a
Site-Specific Ground Motion for Seismic Design with exception of
buildings having a fundamental period of vibration equal to or less
than 0.5 seconds. If the exception is stablished the site class is
permitted to be determined in accordance with section 20.3 and the
corresponding values of Fa and Fv determined from Tables 11-4-1
Application of Standard Code
requirements are not expected to alter the project design. X Recommended conditions of
approval are attached.
Application of Standard Code requirements or the attached conditions of approval will substantially impact or alter
the design of the project.
I contacted the applicant on
To schedule an appt. for Code review
To discuss the following (see notes)

and 11-4-2. The geotechnical report must also provide estimated
differential settlement for the proposed structure and proposed 30”-
inch and 24”-inch sewer lines along with remedial recommendations
to prevent damage. Provide specifications for the construction and
removal of existing lines.
