Converse Consultants - City of Moreno Valley

9.0 Conclusions and Recommendations
Converse has performed a Phase I Environmental Site Assessment in general
conformance with the scope and limitations of ASTM Practice E1527-05 for the Nason
Street Alignment, an approximate 2-mile stretch from Damascus Road to just south of
State Route 60 (Moreno Valley Freeway) in Moreno Valley, Riverside County,
California. Any exceptions to or deletions from this practice are described in the
Limitations and Exceptions of Assessment section of this report. This assessment has
revealed no evidence of recognized environmental conditions in connection with the
property except the following:
• The east and west properties were historically used for agriculture as early as 1938
until at least 2002.
Based on this assessment, Converse has the following conclusions and
recommendations:
• The historical agricultural use of the east and west adjoining properties is a HREC.
Agricultural chemical residues may be present in the surface and subsurface soils.
Portions of the east and west adjoining properties have either been redeveloped or
graded and concentrations of agricultural chemicals are not anticipated to be greater
than regulatory levels due to mixing and turning of the soil. Further assessment
does not appear warranted in these areas.
Portions of the east and west adjoining properties that are currently vacant and have
not been redeveloped or graded may contain residual agricultural chemicals. The
boundaries adjacent to Nason Street of the following parcels should be assessed for
the potential presence of agricultural chemical residues if they are to be affected by
the realignment project: APNs 486-280-028, 486-290-032, 486-290-033, 486-290-
035, 486-260-011, 486-260-010, 486-270-019, 487-470-023, 487-470-013, 487-470-
016/17, and 488-190-026.
Information was requested from the OSFM, but was not received in time for inclusion in this
report.
