According to the EDR Report, the subject property contains several small areas that are designated as a wetland, per the National Wetlands Inventory (1994).

Due to poor or inadequate information, EDR is unable to map certain sites. These sites are referred to by EDR as Orphans. No Orphan sites were identified in the EDR Report.

The Aerojet Corporation site boundary encroaches into the subject property in the north-center area and is visible in the EDR Radius Map as a National Priority List Site.

6.2 Review of State and/or Local Government Records
The Sacramento County NextRequest system was used to request any records pertaining to hazardous materials or well records at each individual parcel within the subject property.

Records pertaining to the septic system and private well on the subject site were provided for 12525 Douglas Road (Whitlow property), 12535 Douglas Road, and 12565 Douglas Road (Divine property). Records showing a domestic well at 3450 Grant Line Road (073-0010-011) were provided. The well was permitted to be inactive in February 2015. Past sampling of the well for the Aerojet contamination plume showed that the well had trace level hits of NNitrosodimethylamine (NDMA) and no volatile organic compounds or perchlorate. The well was sealed in October 2014 and destruction of the well was mentioned in an email correspondent with a deadline of 26 December 2014; the well has yet to be destroyed.

Records were also provided for the Teichert Aggregates plant located at 3417 Grantline Road.

Records show that a number of above-ground storage tank (ASTs) are present at the facility and hold a number of different fuels, oils, and lubricants. Past inspection reports were reviewed and no significant violations were discovered; any spills or violations were found to have been corrected to the satisfaction of Sacramento County.

The State of California Water Resources Control Board’s GeoTracker database was researched to identify if sites with groundwater contamination exist within the minimum search distances to the subject property (www.geotracker.swrcb.ca.gov). Also, the Department of Toxic Substance Control’s (DTSC) Envirostor database was researched for sites of environmental concern near or at the subject property (https://www.envirostor.dtsc.ca.gov/public/). The subject property was not identified on the GeoTracker or Envirostor web sites.

The Fall 2018 iso-Concentration maps by Geosyntec Consultants depicting the extent of contamination of the Aerojet area for trichloroethylene, perchlorate, and N-Nitrosodimethylamine (NDMA) were reviewed. The NDMA contours do not intersect the subject property. The maps show that the 5 ppb (parts per billion) contour for TCE in groundwater Layers C and D reach monitoring wells OS-10C1/OS-10C2 located in the southwest of parcel 072-0300-001 (12555 Grant Line Road), partially encroaches into parcel 072-0010-011, and continues west through parcel 072-0300-008 to the west adjacent parcel where extraction well 4757 is located. The 50 ppb contour for Layer C encroaches near the northern part of parcel 072-0300-001, near a monitoring well just outside the north property boundary (well OS-5C).

The 4 ppb contour for perchlorate in Layer C intersects the subject property at the northeast corner of the site within parcels 072-0010-010 and -011. The maximum contaminant level (MCL) for groundwater and drinking water established by the Environmental Protection Agency (EPA) is 5 ppb for TCE and 6 ppb for perchlorate. Perchlorate is found to be below the MCL at the subject property. Perchlorate and perchlorate anions do not volatilize from water or soil surfaces to air according to the Agency for Toxic Substances and Disease Registry (ATSDR) “Toxicological Profile for Perchlorates,” 2008, and was not found to have values for soil vapor or ambient air in screening level criteria tables produced by the EPA and DTSC; perchlorate does not pose a soil vapor intrusion risk. The 5 ppb TCE contour does not intersect any domestic wells within the subject property, but has potential to create a soil vapor intrusion scenario for future development.

According to the Geotracker Website, two Inactive Rancho Cordova Test Sites associated with the past Aerojet Rocketdyne and Boeing activities are located west of the subject property: The Sigma Debris Area and the Antenna Station. Both sites are currently in remediation stages.

The Antenna Station Site, located to the northwest, has been designated that No Further Action is necessary as of February 2005, although monitoring and in situ bioremediation continues.

The Sigma Debris Area was designated as a No Further Action site in a Remedial Action Plan ITEM 11.1. ATTACHMENT 4

and was investigated for soil vapor and contaminated groundwater between 1992 and 2002.

Investigation data shows that the site is not a threat to human health and the environment.

Monitoring continues as part of the IRCTS as a whole.

The 3920 Security Park Drive site was listed on the Envirostor database. The former General Electric Company Facility was once known as the Administration Area within the Inactive Rancho Cordova Test Site. GE Medical Systems were given authorization to operate a wastewater treatment system and discharge treated wastewater to the facility’s septic system and leach field. The treatment system was moved to the neighboring address adjacent to a hazardous waste storage area. An approval of the Closure Certification for the GE facility was issued on June 28, 1991. A Termination of Corrective Action was also issued in July 2009 which was relied almost entirely upon data in a report titled “Remedial Action Plan for the Unsaturated Zone Administration Area IRCTS” dated August 2000 by ENSR.

6.3 Vapor Encroachment Screening
Vapor intrusion is the term used to describe the migration of volatile organic compounds (VOCs) via soil vapor from the sub-surface soil and/or groundwater upward into buildings, potentially causing unacceptable chemical exposure for building occupants. The vapor intrusion pathway is evaluated using the Conceptual Site Model (CSM) and vapor intrusion pathway screening.

Volatilization of petroleum products in the subsurface occurs via the volatilization of constituents that are in the dissolved phase (in pore water or groundwater), volatilization from light nonaqueous phase liquid (LNAPL) (either mobile or residual) directly, and volatilization from impacted soil. Once the individual constituents are in the vapor phase, they can continue to migrate in the vadose zone (soil zone between first groundwater and ground surface).

Transport will occur through diffusion caused by concentration gradients. The greatest movement will take place in the most permeable materials. If the soil-moisture content in the vadose zone is high, then relatively soluble compounds such as ethanol and MTBE will tend not to stay in the vapor phase, but rather will stay in the soil moisture.

Soil vapor is one of the pathways of contamination to the subject property, along with ground water and soil. ASTM E1527-13 requires that vapor migration be treated no differently than contaminated groundwater. The soil vapor contaminant pathway needs to be considered in evaluation of RECs or other environmental concerns. The ASTM Standard Guide for Vapor Encroachment Screening (VES) on Property Involved in Real Estate Transactions (ASTM E2600-10) is the industry-accepted guidance for using Phase I ESA information to determine if a vapor encroachment condition (VEC) exists at the subject property. EDR’s Vapor Encroachment Worksheet was designed to assist parties seeking to meet the search requirements of the ASTM E 2600-10. The Aerojet Rocketdyne, Inc. site was identified during our VES on the property to have a potential to create a soil vapor intrusion scenario. A copy of the EDR VES is provided in Appendix D.

7.0 SITE RECONNAISSANCE

7.1 Purpose
A reconnaissance of the subject property and a windshield survey of the surrounding area were conducted by Youngdahl Consulting Group, Inc. on 9 May 2019. Views of the subject property at the time of the reconnaissance visit are presented as Figures 3 - 28.

7.2 Subject Property
Some features discussed in this section are shown on the Site Plan – Figure 2.

ITEM 11.1. ATTACHMENT 4

Page 1544 of 3764 ends

APNs 073-0010-011 & -010 (3450 Grant Line Road)
These parcels are adjoining with 073-0010-010 being a small parcel northeast from 073-0010- 011. Collectively, they comprise the east portion of the subject site and together are triangular in shape (Figure 2). The majority of 073-0010-011 is vacant grazing land (Fig. 3), but an orchard of olive trees was observed in the northeastern corner of the parcel (Fig. 4, Photo 3).

The orchard also occupies the entirety of APN 073-0010-010. Just south of the orchard is an area once occupied by a residence and was observed to have miscellaneous building debris (Fig. 4, Photo 4); no remnant of the building foundation was observed. Wood poles were also observed near the former residence (Fig. 5, Photo 5). More debris and a dilapidated shed were observed west of the location of the former residence (Fig. 5, Photo 6). A standing wood pole was observed just north of the dilapidated shed (Fig. 6, Photo 7). Near the southwest corner of the orchard, a shallow, rectangular pit (Fig 6, Photo 8) and stockpiled material (Fig. 7, Photo 9) was observed near Morrison Creek. More miscellaneous debris was observed within the orchard (Fig. 7, Photos 10 & 11). An inactive domestic well was observed southwest of the former residence location (Fig. 9, Photo 12). Two steel pipes were seen protruding from the ground to the northwest from the dilapidated shed (Fig. 8, Photo 13).

APN 072-0300-002 (12565 Douglas Road, Divine Property)
This parcel occupies the south-center portion of the subject property (Figure 2) and consists of an existing single-family home, a separate garage structure located east of the home (Fig. 9, Photo 14), a small shed just south of the garage outbuilding (Fig. 9, Photo 15), and vacant grazing land to the north and south of the home (Figure 10). Morrison Creek runs through the northern portion of the property, trends generally east-west, and was observed to be dry at the time of our reconnaissance. A fire break was observed north of the home. Oil staining was observed on the graveled area in the vicinity of the east garage building and near stored farm equipment (Figure 11). No large quantities of chemicals and/or fuel were observed in or around the east garage outbuilding. A drastic vegetation change was observed in the southern grazing land, potentially from the previously identified (Youngdahl, 2017) areas where organics were being dumped (Fig. 12, Photo 21). The existing residence is supplied by a well located west of the home; a propane tank was also observed in this area (Fig. 12, Photo 22).

APN 072-0300-005 (12525 Douglas Road, Whitlow Property) This property comprises the southwest section of the subject property and is primarily grazing land (Fig. 13, Photo 23) with a residence along the east-center property line (Fig. 13, Photo 24).

Near the residence is an associated well house to the west and a shop/shed building to the south of the well house. A corrugated metal cattle shed is just west of the residence and associated outbuildings (Fig. 14, Photo 25). The well house is northwest from the home (Fig. 15, Photo 26) and the interior is used as storage and to contain the water well (Fig. 15, Photo 27). A wood pole, concrete pad with concrete-filled steel drums, and remnant concrete foundation for a pole were observed north of the residence in the grazing field (Fig. 15, Photos 28 & 29). Additional wood poles are located in the north-center portion of the subject site at Morrison Creek (Fig. 16, Photo 30). The portion of Morrison Creek was observed to be artificially leveed and dammed (Fig. 16, Photo 31).

APN 072-0300-001 (12555 Grant Line Road)
This parcel is at the north-center portion of the subject site and consists of vacant grazing land (Figure 17). Standing water in a vernal pool was observed in the approximate center of the parcel. A monitoring well was observed near the southwest corner of the parcel (Figure 18).

APN 072-0300-008 (12535 Douglas Road)
This parcel is primarily vacant grazing land in the north (Fig. 19) with a residence and associated outbuildings in the southwest corner and a pond in the southeast corner.

ITEM 11.1. ATTACHMENT 4

Page 1545 of 3764 ends

Miscellaneous debris was found to be dumped inside, around, and to the north of the outbuildings. 55-gallon drums observed among the waste to the north of the buildings were found to be primarily used for trash or empty (Fig. 20, Photo 36) except for one drum which was sealed and contained an unknown liquid (Fig. 20, Photo 37). All automotive tanks and parts were observed to be empty (Fig. 21, Photo 38). A small stockpile with discarded tires was also found in the field (Fig. 21, Photo 39). The interior and exterior of the shed located near the debris in the field was filled with more trash and other solid waste; any fuel or chemical containers were empty (Fig. 22). Several sheds and a chicken coop were observed near the residential home which all contained miscellaneous debris and were in late stages of deterioration (Figs. 23, 24, & 25). The western shed had a storage room with miscellaneous items inside (Fig. 25, Photo 47). Underground utilities were observed around the outside walls of the northmost outbuilding including a storage tank of unknown use (Fig. 26). The residence was observed to be vacant and the windows and doors have been boarded up (Fig. 27, Photo 50). A domestic water well was observed just east of the home; a pressure system and filter were in place as a precaution for the contamination plume from the Aerojet General Corp. site (Fig. 27, Photo 51). A pond is created from a section of Morrison Creek being dammed at the southeast corner of the parcel (Fig. 28).

8.0 CONCLUSIONS, OPINION, AND RECOMMENDATIONS
This Phase I Environmental Site Assessment (ESA) was performed for the Preserve, which comprises the following Sacramento County Assessor’s Parcel Numbers (APNs):

ITEM 11.1. ATTACHMENT 4

This Phase I ESA was conducted for the Winn Communities. Our study consisted of a review of environmental record sources, physical setting sources, review of site related documents, historical use information, and a site reconnaissance. We have performed a Phase I Environmental Site Assessment in conformance with the scope and limitation of ASTM Standard Practice E 1527-13. Any exceptions to, or deletions from, this practice are described in Section 1.0 of this report.

8.1 Summary of Historical Subject Property Use Information Date Source Subject Property Observations
1891-2016
Topographic
Maps and
Aerial Photos
The property had been primarily vacant grazing land with several residences that were constructed starting sometime between 1980 and 1984 with the last residence being built sometime between 1993 and 1998.

8.2 Recognized Environmental Conditions (RECs)
Recognized environmental conditions (RECs) are defined in the ASTM Phase I Standards to mean "the presence or likely presence of any hazardous substances or petroleum products in, on, or at a property: (1) due to release to the environment; (2) under conditions indicative of a release to the environment; or (3) under conditions that post a material threat of a future release to the environment.”
A contaminant plume of trichloroethylene (TCE) was discovered to encroach within some of the northern parcels. The 5 parts per billion (ppb) contour of TCE (the maximum contaminant level) extends to onsite and adjacent monitoring wells, but does not extend to any domestic wells identified on the subject property. Although existing domestic wells aren’t necessarily impacted, the presence of TCE within subject property boundaries has potential to create a soil vapor intrusion scenario and is considered a REC.

Two steel pipes were observed protruding out of the ground within parcel 073-0010-011 (3450 Grant Line Road). An inactive well was also observed, and we understand that is currently permitted as inactive. It is our opinion that the two protruding pipes have potential to be connected to an underground storage tank (UST), which is considered a REC. The orchard that occupies a portion of this parcel and parcel 073-0010-010 was planted sometime between 1980 and 1984, as indicated by the historical aerial photography and topographic maps, which means that lead arsenate and organochlorine pesticides were not likely used.

The residence and outbuildings within APN 072-0300-008 (12535 Douglas Road) were built sometime between 1975 and 1980, and the structures and soils adjacent to these structures have potential for containing lead-based paint; this has been identified to be a REC. Within APN 072-0300-008 is an unknown underground system found adjacent to the shed located north of the residence and a 55-gallon drum northeast from the residence with an unknown liquid inside; these are considered RECs if these vessels were used for fuel storage.

ITEM 11.1. ATTACHMENT 4

Page 1549 of 3764 ends

All residences and major outbuildings of wood construction on the subject property besides within APN 072-0300-002 (12565 Douglas Road, Divine Property) have the potential for termiticides present in adjacent soils and are considered RECs.

8.3 Historic Recognized Environmental Conditions (HRECs) Historic recognized environmental conditions (HRECs) is a term used to state that the property only includes a resolved or closed out REC that has been completely resolved (“clean closure”) with no restrictions. This assessment did not identify any HRECs in connection with the subject property.

8.4 Controlled Recognized Environmental Conditions (CRECs) The new term controlled REC (CREC) describes closed RECs that are managed under an activity and use limitation (AUL). This assessment did not identify any CRECs in connection with the subject property.

8.5 Recommendations
It is the opinion of the Youngdahl Consulting Group Inc. that the following recommended actions be conducted for the identified RECs:

buildings should be sampled
for total lead in surface soils
and termite pesticides at a
depth of approximately 1 foot.

ACBM should be investigated
at the main residence and
shed northwest of the
residence by a licensed
asbestos contractor. Soil
vapor sampling as part of a
soil vapor intrusion
investigation should be
conducted.
072-0300-010 (No Address) No RECs identified. No recommendations.

investigation should be
conducted.

Additionally, all inactive wells that are not planned for future use should be destroyed per Sacramento County requirements. Domestic wells were observed to be within parcels 073- 0010-011 (permitted inactive), 072-0300-002, 072-0300-005, and 072-0300-008.

8.6 Data Gaps
According to § 3.3.20 of ASTM Standard E 1527-13 a data gap is a lack of or inability to obtain information required by the ASTM Standard despite good faith efforts to gather same. Data gaps may result from incompleteness in any of the activities required by the ASTM Standard. It is our opinion that no significant data gaps were identified.
