<br /> (3) 2529 Broadway
<br /> This site contains two parcels, but with only one structure, as discussed in the Phase I ESA-2529 Broadway (p. 9), a
<br />former party equipment rental building in the northern parcel and a paved parking area with some landscaped islands
<br />in the southern parcel. The Phase I ESA-2529 Broadway discusses the site of the current buildings as well as adjacent
<br />and nearby properties; conducted a site visit, reviewed available information and environmental data relating to the
<br />property; interviewed persons with knowledge of the site; reviewed maps and aerial photographs of the site; and
<br />reviewed records maintained by federal, state, and local regulatory agencies. The Phase I ESA-2529 Broadway
<br />evaluated information on recognized environmental conditions (RECs) in connection with the property, . but did not
<br />identify any RECs, controlled recognized environmental conditions (CRECs), or historical recognized environmental
<br />conditions (HRECs). The report also evaluated de minimis conditions related to limited exterior surface staining,
<br />which “appears to have resulted from minor oil releases from customer vehicles” and did not seem “indicative of a
<br />widespread release” (pp. 22, 24) on the property. Finally, the Phase I-2529 Broadway discussed two conditions (see
<br />directly below) that do not fit into the set of ASTM definitions and are classified in the Phase I as “other findings.”
<br /> The site was developed for commercial uses in the 1940s; construction of the existing site structure occurred prior to
<br />1943. The building switched owners until the early 1980s when it was vacant. The party rental operation began in
<br />about 1985 (p. 17).
<br /> The Phase I ESA-2529 Broadway (pp. 4-5 and 26-27) concluded that there is no evidence of RECs; however, two
<br />”other findings” were of note: (1) potential migration of offsite contamination from the Unocal Station
<br />(#0060)/Robison Property/Holloway Cleaners property, which is approximately 300 feet from the 2529 Broadway
<br />site to the west; and (2) past operations both at the 2529 Broadway site and surrounding properties, in particular
<br />gasoline, oil, and grease storage facilities to the east, a gas station to the north, and printing and painting shops west
<br />across California Street. However, the Phase I ESA-2529 review did not “identify documentation of a release, a
<br />suspected release, or a potentially material threat of a release of a hazardous substance or petroleum product” and
<br />these could not be considered RECs. The Phase I ESA-2529 Broadway did not recommend further evaluation at this
<br />time.
<br /> The Phase I ESA-2529 Broadway identified one de minimis condition related to limited staining of exterior surfaces,
<br />especially near drains. Considering the limits of the stain from its minimal coverage plus the intact pavement, the
<br />item does not represent a material risk of harm to public health or the environment.
<br /> Because the Commercial Component proposes demolition of the existing buildings to redevelop the site, the Phase I
<br />ESA-2529 Broadway concluded a comprehensive ACM survey would be required prior to any renovation or
<br />demolition activities at the site (p. 29). Also based on the age of the onsite building, the Phase I ESA-2529 Broadway
<br />concluded that “it is possible that lead-based paints were used historically on facility structures” though during the
<br />site visit the paint of observed surfaces was in fair condition (p. 30).
<br /> (4) Soil Investigation Report
<br /> The Soil Investigation Report was prepared by Ramboll US Corporation (September 19, 2023) at the request of Union
<br />Pacific Railroad (UPRR) to evaluate chemical soil characteristics in shallow soils on two parcels that historically have
<br />been near railroad land use. Two soil samples were taken, one on California Street and one in the parking lot driveway.
<br />Laboratory results indicate that no chemicals were detected (e.g., metals, PAHs, PCBs, TPH-g/d/mo) that were above
<br />their respective screening criteria. Also, no chemicals typically associated with railroad use (PAHs, TPH, lead and
<br />arsenic) were detected above the criteria for unrestricted land use with the exception of arsenic. Arsenic was detected
<br />at concentrations within the accepted regional background levels. The Soil Investigation Report (p. 3) concluded that
<br />no further evaluation would be recommended based on this investigation.
<br /> Conclusion
<br /> In conformance with the DTPP program EIR (Chapter 14, Hazards and Hazardous Materials, pp. 14-13 through 14-
<br />16) and the DTPP Plan-Wide Amendments program SEIR (Chapter 14, pp. 14-8 through 14-9), regarding hazardous
<br />materials, ACM, PCBs, and LBP, the proposed Commercial Component would continue to be subject to all applicable
<br />existing local-, county-, regional-, State- and federally- mandated site assessment, remediation, removal, and disposal
<br />requirements of the City of Redwood City, San Mateo County Environmental Health Department (SMCEHD),
<br />Regional Water Quality Control Board (RWQCB), California Department of Public Health (CDPH), California
<br />Department of Toxic Substances Control (DTSC), and other responsible agencies. This requirement entails continuing
