KLEiNFELDER 1. SUMMARY Kleinfelder, Inc. (Kleinfelder--) conducted a Phase I Environmental Site Assessment (ESA) for Andronico at a site in Petaluma, California. The site is being 'considefed for development as a City Fire Department. This report documents the findings of,Kleinfelder's assessment. In �, summary: The site is located at 3.07 Petaluma.Boulevard South, Petaluma, ;California (Plate 1). A u-shaped 22-room motel occupies .the approximately %Z-acre rectangular parcel. The remaining area is covered by a concrete -paved packing.lot. Adjacent land uses iriclude; residential; commercial, retail office-, and light industrial uses. According to Sanborn Fire Insurance Maps (Appendix B), the site was undeveloped from 1885 to sometime between 1910 and 1923'. During this time, the site was developed for use by the Petaluma Electric Incubator, :Company. The incubator 7company remained at the site until sometime • between 1923 and 1'949: By 1949, the current motel occupied the site. These businessesi did not likely 'involve the, use, storage, or possible release o.f hazardous chemicals. The site was not listed in the federal', state or local regulatory agency databases of 'businesses or properties that handle hazardous materials or waste, of ate known locations of a release of hazardous substances. No •properties.:immediately adj acent to, or surrounding the site were listed. Kleinfelder did not observe evidence of the use; storage or release of hazardous 'substances or petroleum products at the site other than relatively small amounts of janitorial and cleaning . supplies.

Munger Map Book According to page W-17 of the Munger Map, Book .(1993), there are°no oil or gas wells mapped nearthe site: 39393\,SR04R002 Page 5 of 17 January 9, 2004 m 2004, Kleinfelder, Inc. KLEINFELDER 3.2 SITE SOILS r . ` y According to the Soil Survey .of ,S,onoma County, California, site soils are mapped as Yolo clay loam. This soil consists of'w;ell-drained lo,ams underlain by recent alluvium from sandstone and shale and is found on alluvial, fans and flood plains., Permeability of this soil is moderate, runoff is slow and the hazard of erosion is,sfight. 3.3 REGIONAL AN LOCALSITF GEOLOGY The site lies within the Coast :Range Geologic _Province of California. This province is characterized by northwest atrending ,mountain 'ranges and intervening valleys, which are a reflection of the dominant northwest, structural trend inbedrock of the region. The basement rock in the northwest . ' ortion: of &s,• province p ` p ince is dominantly' highly, deformed sedimentary, metamorphic and volcanic rock 'of the Franciscan Complex of Upper Jurassic to .Cretaceous Age. u .. In the site vicinity, these rocks have' been unconformably overlain by Tertiary age, continental and marine sedimentary and" volcanic rocks. - Younger alluvial, colluvial and landslide deposits have overlain these, locally. According to Geology for,Planning in,Sonoma County, California, the site geology is mapped as alluvium, which consists ofsand,'gravel, silt and clay. 3.4 GROUNDWATER The published groundwater resources -reviewed for "this 'assessment did not contain information specific to the groundwater,conditions at the subject 'site.- However, Kl'einfelder'.s 'experience with, other sites in the ;area suggests that groundwater is likely to occur at :a depth of 15 to 18 feet below ground surface"and flows northwest to northeast. 39393\SRNR002 Page 6 of 17 January 9, 2004 ® 2004, Kleinfelder, Inc. K.LEINFELDER 4. HISTORY OF TH'E-:SITE The history of the site was researched to identify obvious use of the Site from the,present to first 'developed use, or back to 1940, whichever is earlier. The objective was to evaluate the likelihood that past uses resulted in Recognized Environmental Conditions. Table 4.1 summarizes the information reviewed during this assessment. Kleinfelder used this information to establish the site history.

RECORDS REVIEW 5.1 REGULATORY AGENCY DATABASE REVIEW The purpose of the records review is to obtain and review records that would help to reveal recognized environmental conditions at orin the area around site. Federal, state and local regulatoryagencies publish databases, or "lists" of businesses and - ---properties that handle - hazardous matenals.. or -:waste, _ orb are =known loc P P ations - of a -release of - - -- - - _ - - - --p -- hazardous substances. These databases are -available for review or purchase at the regulatory Iagencies, or they can be obtained through..a commercial. database service., Kleinfelder contracted with a commercial database ,service, Environmental Data Resources, Inc.-.(EDR),.to review the 9' agency lists for references to the -site and any listings within the ,appropriate ASTM_ minimum search distance from the site. The executive summary and maps from the database search report are included in Appendix A, Regulatory Agency Database Summary. The federal and state databases reviewed are summarized on Table 5.1.

January 9, 2004 A summary of facilities listed in -the databases is presented, in the executive summary of the EDR report and each facility is cross-referenced with a radius map showing the location of the listed facility with respect to the subject property (Appendix A). Kleinfelder conducted a review of the EDR report to assess which listings have a si;gri feant potential to impact the subject property. Factors used to screen the listed properties include distance to the' -site, geology, presumed or known direction of groundwater flow, type, and magnitude of hazardous material release, and nature of sensitive receptors. -Those considered to have,'a significant potential to impact the site were then subjected to a .file review at appropriate regulatory agencies. No facility files were reviewed for this. assessment, .-because,,yin__Kleinfelder's_opinion ,,the -'facilities _are located- either down -gradient or cross -gradient; of the site and groundwater is carrying contaminants away from the site; and because soils in he area consist of dense clay that typically restricts movement of Petroleum hYdrocarbons and groundwater. The site was not listed in the databases reviewed. There were no1acilities adjacent to the site listed. Five releases of hazardous chemicals that 'have affected soil and groundwater have occurred within a''/a-mile radius of the site. 5.2 REGULATORY AGENCY CONTACTS Local and state regulatory agencies were contacted for reasonably ascertainable and practically reviewable information regarding Recognized Environmental Conditions present at or adjacent to the site. The information wasp obtained by interviewing agency,representatives -or reviewing local j agency records. 39393\SR04R002 m 2004, Kleinfelder, Inc.
