Petco
Park
and East Village Redevelopment Area
San Diego, CA
 |
|
This project involved the
redevelopment of a 26-block area of downtown San Diego. The East
Village Redevelopment Area had been occupied by various
commercial and industrial land uses dating back to the late
1800s and by residential land uses going back as far as the
mid-1800s. This area has been successfully redeveloped with
numerous hotels, condominiums, restaurants, parking garages,
and, of course, Petco Park, the baseball stadium for the San
Diego Padres.
SCS Engineers (SCS),
provided services for Center City Development Corporation (CCDC)
on over 175 parcels owned by over 100 separate property owners.
SCS' services have included: conducting Phase I and Phase II
environmental site assessments; preparing a multi-volume Phase I
site assessment of 35 blocks, an area-wide “master” workplan,
unique property mitigation plans, health and safety plans, and a
community health and safety plan; providing project management;
providing oversight of other environmental consultants;
preparation of health risk assessments and site conceptual
models; development of risk-based corrective action levels; and
remediation of 19 blocks of the project area. SCS also provided
assistance in Polanco Act cost recovery efforts, litigation
support, and expert witness testimony on behalf of CCDC.
Most of the assessment and nearly
all of the remediation activities for the project have been
self-performed by SCS through either agreements with the
property owners or as a result of legal action taken by CCDC (Polanco
Act). The assessments and remediation have involved geophysical
surveys, preparation and implementation of sampling plans,
rapid site assessment with direct-push drill rigs and mobile
labs, exploratory trenching, in situ groundwater sampling, soil
vapor surveys, installation /development of groundwater
monitoring wells, and the innovative use of x-ray fluorescence
for the real-time field-screening of soil for lead.

STAPLES ARENA
PHASE II INVESTIGATION
Los Angeles, California
 |
|
For the Community Redevelopment
Agency of the City of Los Angeles (LACRA) and the LA Arena
Company, SCS completed numerous Phase II investigations and
remediation projects on properties located within an area near
the existing Los Angeles Convention Center, which is part of the
support area for the new Staples sports arena.
Review of information and
available reports by SCS indicated that additional
investigations were required at over 30 properties within the
area. Past or existing operations on these properties included
automobile repair, painting, metal plating, and printing.
Several underground storage tanks, hydraulic hoists, clarifiers,
sumps, and painting booths were determined to have been present
on the properties. A geophysical survey of the properties was
conducted to identify possible underground structures and
utilities prior to implementing the investigation. Mobile
laboratories were used, whenever possible, to expedite sample
turn around and assist in directing the investigations in the
field.
The investigations identified
several properties within the area where remediation was
warranted. In addition, several under-ground storage tanks were
identified on the property, which required removal in accordance
with regulatory requirements.
SCS removed the contaminants
and underground tanks with the oversight of various regulatory
agencies. At the completion of remedial activities and following
removal of underground tanks, soil and groundwater samples were
collected for chemical analysis, to comply with regulatory
requirements.

FORMER KAISER
STEEL CORPORATION
Los Angeles, California
 |
|
Significant remedial action was
initiated and completed on a 500-acre Brownsfield site in
Fontana, California, under the oversight of the Department of
Toxic Substances Control. Fast-track remediation was initiated
and completed within a 5-month period due to site development
plans, which included construction and completion of the Roger
Penske Auto Raceway in early 1997.
Remedial actions included design
and construction of a 14-acre synthetic membrane cap,
construction, in-situ soil vapor extraction, excavation, on-site
soil treatment, and off-site disposal of over 7,000 cubic yards
of impacted soil, and treatment of 21,000 tons of residuals from
air pollution control systems. Verification sampling, analysis,
and health risk screening were also completed. This rapid
remedial action was possible only through close coordination of
simultaneous completion of multiple remediation tasks involving
continuous communication between the site owner, regulatory
agencies, and contractors.

PORTCENTRE
COMMERCE PARK
Portsmouth, Virginia
 |
|
Portcentre Commerce Park
constitutes more than 22 acres of prime commercial and light
industrial real estate in Portsmouth, Virginia. Portcentre is
located near deepwater ports, interstate highways, and
railroads. However, the former Abex Foundry, an NPL Superfund
site, borders the Park to the west.
SCS has provided environmental
assessments and remedial design services for various agencies of
the City of Portsmouth since 1988. Seventeen assignments have
been performed to date, including wetland assessments, Phase I
Environmental Assessments, and a number of site investigation,
evaluation, and remediation assignments.
Several projects involve sites
located within or near the Abex Foundry and other Superfund
sites, and three assignments relate to emergency orders of the
U.S. Environmental Protection Agency. In each instance, SCS
assisted the City in overcoming stigma and promoting productive
use of stigmatized land parcels.
