INTRODUCTORY FACT SHEET
MARINA VILLAGE SHOPPING CENTER
2250 MARINA BLVD.
SAN LEANDRO, CALIFORNIA 94577
Cleanup Program Site Case No. RO0003448
Summary – This fact sheet has been prepared to inform
community members about environmental activities
being conducted at the Marina Village Shopping Center at
2250 Marina Blvd. in San Leandro (Site). 3156 24th Street,
LLC, the property owner, is working under the oversight
of the Alameda County Department of Environmental
Health (ACDEH) to voluntarily investigate and clean up
solvents that were released to soil and groundwater from
former dry cleaners that operated on the property. This
fact sheet contains information on the Site,
environmental investigations and mitigation measures
completed, and next steps.
Site Background – The Site is located at Marina Boulevard
and Doolittle Drive in San Leandro and is surrounded by
residences to the west and south, retail to the east, and
residences and industrial buildings to the north. The Site
consists of two commercial buildings, containing six
businesses and has historically been used for retail. From
the 1960s to the 1980s, the Site had various dry-cleaning
businesses which have resulted in releases of dry-cleaning
solvents to the underlying soil and groundwater.
Environmental Investigations – Multiple investigations
have been conducted at the Site since 2021. These
investigations have identified elevated concentrations of
tetrachloroethene (PCE) in soil, soil vapor (the air spaces
between grains of soil), groundwater and indoor air. Recent
investigations have documented PCE in indoor air in
building tenant spaces that has migrated from the
subsurface through the building foundations in a process
called vapor intrusion.
Next Steps – Environmental consultants representing the
owner of the Site will be conducting the following work:
• Further sampling of soil vapor and groundwater on
Site.
• Conducting off-Site investigations to determine if
contamination is present in groundwater and soil
vapor.
• Developing interim mitigation measures to reduce
vapor intrusion risk to on-Site tenants.
• Developing a cleanup plan to address
contamination and ensure the long-term
protection of public health and the environment.
Mitigation Measures – While a long-term cleanup plan is
being developed, the owner of the Site will be
implementing mitigation measures, which are intended to
lessen the impacts of vapor intrusion to on-Site tenants.
These measures may include installation of air purifiers into
building tenant spaces, modification to the heating and
ventilation systems for the buildings, and installation of
engineering controls to prevent soil vapor from entering
the buildings on- and off-Site.
For More Information – For more information, please
contact Tracy Craig, Community Outreach, (510) 334-4866
or tracy@craig-communications.com.
ACDEH will send out additional fact sheets to notify
tenants and the community of additional
investigation activities and cleanup and mitigation
measures being considered for approval by ACDEH.
