Agenda Item No. 6
CITY COUNCIL STAFF REPORT
TO: Honorable Mayor and City Council DATE: April 10, 2023 FROM: Matthew Bronson, City Manager
PREPARED BY: Greg Ray, Public Works Director/City Engineer SUBJECT: Authorization for Purchase of Real Property at 0 Calvin Court
RECOMMENDATION
Provide ratification and approval of the escrow and contract for the purchase agreement for the property at 0 Calvin Court identified as Assessor’s Parcel Number 060-543-007.
BACKGROUND
Property located at 0 Calvin Court in Grover Beach was listed for sale in January of 2023. The property is located near the corner of Calvin Court and South 4th Street, is approximately 0.5 acres in area and is bounded by S. 4th Street, Calvin Court, Huber Street and Griffin Street. The property is vacant, undeveloped and is currently fully covered by Eucalyptus trees. The property is identified as Assessor’s Parcel Number 060-543-007 and is depicted in the map below with an aerial view of the property on the following page:
Staff Report: Property Acquisition for 0 Calvin Court Page 2 April 10, 2023
This property is adjacent to the Central Coast Blue treatment facility site under development to the north of this property. The Central Coast Blue partner agencies have identified benefits in using this property to expand the Central Coast Blue project footprint, route proposed water and sewer mains away from the proposed homeless housing facility located nearby on South 4th Street, and provide additional buffers between the treatment facility and the surrounding uses. It is anticipated that this property once acquired would ultimately be transferred to the Central Coast Blue Joint Powers Authority (JPA) and the City would be reimbursed for the portion of the cost beyond the City’s cost-sharing percentage in the Central Coast Blue project.
Staff has negotiated a price of $200,000 to acquire the property along with a waiver of approximately $3,000 in City penalties assessed on the property for failure to maintain the property and hazardous conditions related to the condition of the trees. The property currently is liened by the Five Cities Fire Authority (FCFA) in the amount of $11,000 for other weed abatement and cleanup. The seller is responsible to pay off this lien as part of this transaction but the City will assure the FCFA receives payment. A phase 1 Environmental survey was performed to identify any record of uses that could result in contamination of soils or groundwater on the property and the result determined that there are no records indicating a potential for contamination.
The current property owner put the subject property on the market for sale in January 2023. The importance of the property for future City interest along with the interest in using this lot by the Central Coast Blue project required immediate consideration of acquisition. The Central Coast Blue JPA Board also provided direction to consider the purchase of the property for the needs of the project. Staff entered into a purchase agreement and escrow for the purchase of this property on February 2, 2023 to assure the ability to consider this property for use by CCB or the City with an escrow closing of April 24, 2023. Due to the timing of needing to complete this transaction, Staff Report: Property Acquisition for 0 Calvin Court Page 3 April 10, 2023
staff is requesting Council ratification and approval of the purchase agreement to ensure the timely acquisition of this real property for public benefit.
ENVIRONMENTAL IMPACT
Acquisition of the property is covered by the common sense rule exemption that CEQA applies only to projects which have the potential for causing a significant effect on the environment. It can be seen with certainty that there is no possibility that the acquisition of the property may have a significant effect on the environment. Therefore, the activity is not subject to CEQA (CEQA Guidelines Section 15061(b)(3)). A Common Sense Rule Exemption will be filed pending Council action related to the purchase.
FISCAL IMPACT
The recommended action would result in the City purchasing the property for $200,000, waiving approximately $3,000 in City penalties, and providing assurance to FCFA for payment of the $11,000 in liens which are the responsibility of the seller. The City’s cost would be paid from the Water Fund. Subject to future actions by the CCB JPA, The City is expecting to be reimbursed for approximately $136,000 of the total cost by the other participating agencies in Central Coast Blue with the City’s remaining cost at $64,000.
ALTERNATIVES
The City Council has the following alternatives to consider:
1. Ratify and approve the February 2, 2023 purchase agreement and escrow for the acquisition of the subject property.
2. Provide alternative direction to staff.
PUBLIC NOTIFICATION
The agenda was posted in accordance with the Brown Act.

2. Several nearby automotive repair shops and junk/vehicle storage yards Deviations from ASTM Standard
1. Deviation resulting in possible data gap (User Questionnaire not completed) Because we have no evidence indicating that the subject property has been impacted by hazardous materials or petroleum products, no additional assessment is recommended. However, to evaluate the potential subject property impact associated with the reported PFAS in groundwater, we recommend that the user contact Newsom Springs Mutual Water Company or the potable water provider for the City of Grover Beach. Additionally, we recommend that the solid waste and equipment observed on the subject property be removed and disposed of offsite.

1 Introduction
This report presents the findings of a Phase I Environmental Site Assessment (ESA) conducted for the Central Coast Blue Project property located in Grover Beach, California (subject property; Figure 1). The Phase I ESA was performed by Rincon Consultants, Inc. (Rincon) for the City of Grover Beach in general conformance with American Society for Testing and Materials (ASTM) E1527-21, our proposal dated February 13, 2023, and our contract dated March 7, 2023. The following sections present our findings and provide our opinion as to the presence of recognized environmental conditions (RECs) on the subject property.
1.1 Purpose and Definitions
The City of Grover Beach has requested this assessment and will use the information for the purpose of purchasing the subject property. The purpose of this Phase I ESA was to determine if there are RECs on the subject property, taking into account commonly and reasonably ascertainable information, and to qualify for Landowner Liability Protections under the Brownfields Amendments to the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).
Recognized Environmental Condition (REC)
A REC is defined pursuant to ASTM E1527-21 as,
“(1) the presence of hazardous substances or petroleum products in, on, or at the subject property due to a release to the environment;
(2) the likely presence of hazardous substances or petroleum products in, on, or at the subject property due to a release or likely release to the environment; or (3) the presence of hazardous substances or petroleum products in, on, or at the subject property under conditions that pose a material threat of a future release to the environment”.
As stated in ASTM E1527-21,
“likely is that which is neither certain nor proved, but can be expected or believed by a reasonable observer based on the logic and/or experience of the environmental professional, and/or available evidence, as stated in the report to support the opinions given therein”.
Controlled REC
A Controlled REC is defined pursuant to ASTM E1527-21 as, “recognized environmental condition affecting the subject property that has been addressed to the satisfaction of the applicable regulatory authority or authorities with hazardous substances or petroleum products allowed to remain in place subject to implementation of required controls (for example, activity and use limitations or other property use limitations)”.

Introduction
Rincon Consultants, Inc. 5
Historical REC
A Historical REC is defined pursuant to ASTM E1527-21 as, “a previous release of hazardous substances or petroleum products affecting the subject property that has been addressed to the satisfaction of the applicable regulatory authority or authorities and meeting unrestricted use criteria established by the applicable regulatory authority or authorities without subjecting the subject property to any controls (for example, activity and use limitations or other property use limitations). A historical recognized environmental condition is not a recognized environmental condition”.
De minimis
A de minimis condition is defined pursuant to ASTM E1527-21 as, “a condition related to a release that generally does not present a threat to human health or the environment and that generally would not be the subject of an enforcement action if brought to the attention of appropriate governmental agencies. A condition determined to be a de minimis condition is not a recognized environmental condition nor a controlled recognized environmental condition”.
Property Use Limitation
A Property Use Limitation (PUL) is defined pursuant to ASTM E1527-21 as, “a limitation or restriction on current or future use of a property in connection with a response to a release, in accordance with the applicable regulatory authority or authorities that allows hazardous substances or petroleum products to remain in place at concentrations exceeding unrestricted use criteria”.
Significant Data Gap
A Significant Data Gap is defined pursuant to ASTM E1527-21 as, “a data gap that affects the ability of the environmental professional to identify a recognized environmental condition”.
Notable Finding
Although not defined by ASTM E1527-21, Rincon utilizes the term Notable Finding for potential environmental concerns present at or possibly present at a property that do not specifically fit one of the above ASTM-defined situations, yet may impact current or future use of the subject property.
1.2 Scope of Services
The scope of services conducted during this study is outlined below:
▪ Performed a reconnaissance of the subject property to identify obvious indicators of the existence of hazardous materials.
▪ Observed adjacent or nearby properties from public thoroughfares in an attempt to see if such properties are likely to use, store, generate, or dispose of hazardous materials.

1.3 Significant Assumptions, Limitations, Deviations,
Exceptions, Special Terms, and Conditions
This work is intended to adhere to good commercial, customary, and generally accepted environmental investigation practices for similar investigations conducted at this time and in this geographic area. No guarantee or warranties, expressed or implied, are provided. The findings and opinions conveyed in this report are based on findings derived from a site reconnaissance, review of an environmental database report, specified regulatory records and historical sources, and comments made by interviewees. This report is not intended as a comprehensive site characterization and should not be construed as such. Standard data sources relied upon during the completion of Phase I ESAs may vary with regard to accuracy and completeness. Although Rincon believes the data sources are reasonably reliable, Rincon cannot and does not guarantee the authenticity or reliability of the data sources it has used. Additionally, pursuant to our contract, the data sources reviewed included only those that are practically reviewable without the need for extraordinary research.
Introduction
Rincon Consultants, Inc. 7
Rincon has not found evidence that hazardous materials or petroleum products exist at the subject property at levels likely to warrant mitigation. Rincon does not under any circumstances warrant or guarantee that not finding evidence of hazardous materials or petroleum products means that hazardous materials or petroleum products do not exist on the subject property. Additional research, including surface or subsurface sampling and analysis, can reduce the City of Grover Beach’s risks, but no techniques commonly employed can eliminate these risks altogether.
In addition, pursuant to ASTM E1527-21 practice, our scope of services did not include any inquiries with respect to asbestos-containing building materials unrelated to releases into the environment; biological agents; cultural and historic resources; ecological resources; endangered species; health and safety; indoor air quality unrelated to releases of hazardous substances or petroleum products into the environment; industrial hygiene; lead-based paint unrelated to releases into the environment; lead in drinking water; mold or microbial growth conditions; polychlorinated biphenyl (PCB)-containing building materials (e.g., interior fluorescent light ballasts, paint, and caulk); naturally-occurring radon; regulatory compliance; substances not defined as hazardous substances (including some substances sometimes generally referred to as emerging contaminants) unless or until such substances are classified as a CERCLA hazardous substance; and wetlands.
1.4 ASTM Deviations
Deviations from ASTM E1527-21 practice were encountered during the completion of this Phase I ESA. The User Questionnaire was not returned as of the date of this report. In addition, an environmental lien search was not completed as part of this assessment; however, one was requested from the user.
1.5 User Reliance
The City of Grover Beach has requested this assessment and will use the information for the purpose of purchasing or acquiring the subject property. This Phase I ESA was prepared for use solely and exclusively by the City of Grover Beach. No other use or disclosure is intended or authorized by Rincon. Also, this report is issued with the understanding that it is to be used only in its entirety. It is intended for use only by the City of Grover Beach and no other person or entity may rely upon the report without the express written consent of Rincon.

12 3 Physical Setting Resources and
Government Records
3.1 Physical Setting Resources
Topography
The current USGS topographic map (Oceano Quadrangle, 2018) indicates that the subject property is situated at an elevation of approximately 25 feet above mean sea level with topography sloping down to the west. The adjacent topography is relatively flat. A copy of the current USGS topographic map is included in Appendix B (EDR 2023, page 6).
Geology and Hydrogeology
Based on information provided by the City of Grover Beach and the property owners, there are no site-specific geotechnical or geologic reports available for the subject property.
According to the current USGS Geologic Map (Dibblee 2006), the subject property is underlain by sand from older stabilized dunes.
During the preparation of this Phase I ESA, we reviewed the California SWRCB’s online GeoTracker database to determine groundwater flow direction in the vicinity of the subject property. File reviews conducted for the subject property and/or surrounding release sites indicate that groundwater is typically encountered in the upper 4 to 48 feet below grade with gradients to the west-southwest and south-southwest. The information obtained regarding groundwater in the vicinity of the subject property is listed below:

3.2 Government Record Sources and Agency Records
Review
Rincon outsourced with a regulatory database search contractor, Environmental Data Resources (EDR), to obtain records of sites that generate, store, treat, or dispose of hazardous materials and sites for which a hazardous material release incident has occurred. The regulatory database search was conducted for the subject property and included data from surrounding sites within specified radii of the subject property. A copy of the database report, which specifies the ASTM E1527-21 search distance for each public list, is included as Appendix B. As shown on the March 6, 2023 database report, federal, state, and county lists were reviewed as part of the research effort. Please Physical Setting Resources and Government Records
Rincon Consultants, Inc. 13
refer to Appendix B for a complete listing of sites reported by EDR and a description of the databases reviewed.
The Map Findings Summary, included in the database report, provides a summary of the databases searched, the number of reported facilities within the search radii, and whether the facility is located onsite or adjacent to the subject property.
As a follow-up to the database search, Rincon reviewed regulatory information for the subject property and nearby listings that were interpreted to have the potential to impact the subject property, based on one or more of the factors listed below:
▪ Reported distance of the facility from the subject property; ▪ The nature of the database on which the facility is listed, and/or whether the facility was listed on a database reporting unauthorized releases of hazardous materials, petroleum products, or hazardous wastes;
▪ Reported case type (e.g., soil only, failed underground storage tank [UST] test only); ▪ Reported substance released (e.g., chlorinated solvents, gasoline, metals); ▪ Reported regulatory agency status (e.g., case closed, “no further action”); and, ▪ Location of the facility with respect to the reported groundwater flow direction (discussed in Section 3.1 of this report).
Facilities/properties that were interpreted by Rincon to be of potential environmental concern to the subject property, based on one or more of the factors listed above, are summarized below. In accordance with ASTM E1527-21, contamination migration pathways in soil, groundwater, and soil vapor were considered in our analysis of offsite properties of potential environmental concern.
Because no database-listed sites were interpreted to be of potential environmental concern to the subject property, no agency files were reviewed as part of this research effort.

A review of the CalGEM Online Mapping System indicates that no oil wells are located on the subject property or adjacent properties, or within 0.25 mile of the subject property (CalGEM 2023).
3.4 Review of National Pipeline Mapping System
Records
A review of the National Pipeline Mapping System (NPMS) online Public Map Viewer indicates that no natural gas transmission pipelines or hazardous liquid pipelines are located on the subject property or adjacent properties. Additionally, no pipeline-related accidents or incidents are mapped within 0.25 mile of the subject property (United States Department of Transportation 2023).
3.5 Review of California Statewide PFAS Investigation
Beginning in 2019, the SWRCB sent assessment requirements to property owners of sites that may be potential sources of PFAS. These sites currently include select airports, chrome plating facilities, Department of Defense (DoD) sites, landfills, publicly owned treatment works facilities, and bulk fuel storage terminals and refineries. According to the SWRCB, “PFAS are a large group of humanmade substances that do not occur naturally in the environment and are resistant to heat, water, and oil” (SWRCB 2023).
Our March 2023 review of the California Statewide PFAS Investigation online Public Map Viewer indicates that there are no current airport, chrome plating, DoD, landfill, or publicly owned treatment works facilities with PFAS orders listed as located within 0.5 mile of the subject property (SWRCB 2023). Based on our review of the SWRCB’s March 8, 2023 Bulk Fuel Terminal/Refinery Investigative Order, the subject property is not listed on the Bulk Fuel Storage Terminals and Refineries List (Attachment 1 of the Order). In addition, none of the Bulk Fuel Storage Terminals or Refineries on the list are located within 0.5 mile of the subject property (SWRCB 2023).
Our March 8, 2023 review of the California Statewide Drinking Water System Quarterly Testing Results online Public Map Viewer indicates that perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) were detected in a Newsom Springs Mutual Water Co. (Arroyo Grande) drinking water well located approximately 2.6 miles to the east-northeast of the subject property and tested quarterly as part of a PFAS investigative order (SWRCB 2023). This well contains PFOA and PFOS at concentrations greater than their respective SWRCB notification and response levels.

Potential Vapor Migration
Rincon Consultants, Inc. 27
7 Potential Vapor Migration
The database report and other resources were reviewed to identify nearby known or suspect contaminated sites that have the potential for contaminated vapor originating from the nearby sites to migrate beneath the subject property. Based on the ASTM E2600-15, Standard Guide for Vapor Encroachment Screening on Property Involved in Real Estate Transactions, the following minimum search distances were initially used to determine if contaminated soil vapors from a nearby known or suspect contaminated site have the potential to be migrating beneath the subject property:
▪ 1/10 mile (528 feet) for petroleum hydrocarbons
▪ 1/3 mile (1,760 feet) for other contaminants of concern (COCs) Groundwater depth and flow direction is also utilized to determine risk of vapor migration.
Groundwater in the vicinity of the subject property is reportedly present between 4 and 48 feet and has varying flow directions to the west-southwest and south-southwest (Section 3.1).
Online agency resources are reviewed to determine the extent of the contaminated soil or groundwater plume at known or suspect contaminated sites as specified below:
▪ Onsite or adjacent to the subject property,
▪ Within 100 feet, or
▪ Within the above referenced distances from the subject property and upgradient or crossgradient to the subject property.
Sections 7.1 and 7.2 describe contaminated soil, soil vapor, and/or groundwater plumes of petroleum hydrocarbons (528 feet from the subject property) and other COCs (1,760 feet from the subject property). Per ASTM E2600-15, vapors associated with impacted soil or groundwater present within these distances have the potential to migrate beneath the subject property.
7.1 Petroleum Hydrocarbons
Based on our review of the database report and other information as indicated above, there are no known or suspect petroleum hydrocarbon-impacted sites within 528 feet of the subject property.
Therefore, per ASTM E2600-15, as this distance exceeds the 30-foot distance considered the critical distance wherein such migration may pose a threat to the subject property, there are no potential threats to the subject property posed by the potential migration of petroleum hydrocarbon vapors from listed sites.

1 Reported PFAS in
groundwater within
three miles of the subject
property
According to the California Statewide Drinking Water System Quarterly Testing Results online Public Map Viewer, PFOA and PFOS were detected in a drinking water well located approximately 2.6 miles east-northeast of the subject property at concentrations greater than their respective SWRCB notification and response levels.
It is unknown if this wells is currently in service, or if concentrations of PFAS have an impact on water quality with Newsom Springs Mutual Water Company’s service area.
For information regarding potable water quality provided to the subject property, contact Newsom Springs Mutual Water Company or the potable water provider for the City of Grover Beach.
It is unknown if groundwater beneath the subject property is planned for use onsite; therefore, it is unknown if a further assessment of PFAS in groundwater is warranted at this time.
Notable Finding Contact Newsom Springs
Mutual Water Company
(Arroyo Grande) or the
potable water provider
for the City of Grover
Beach
2 Several nearby
automotive repair shops
and junk/vehicle storage
yards
During our review of the historical records and our onsite reconnaissance, junk/vehicle storage yards were noted to the north, west, and northeast of the subject property.
While these facilities have the potential to utilize hazardous materials, no releases have been reported. Therefore, it is not expected that these properties will impact the subject property.
However, during our site reconnaissance, various solid waste and equipment was observed in the northwestern corner of the subject property. We recommend that this solid waste and equipment is removed and disposed of offsite.
Notable Finding Proper removal and
offsite disposal of solid
waste and equipment
