1.0 INTRODUCTION

Milian, Swain & Associates, Inc.'s (MSA) subconsultant, Amec Foster Wheeler Environment & Infrastructure, Inc. (Amec Foster Wheeler), conducted a Supplemental Phase I Environmental Site Assessment (ESA) for sections (designated as Character Zones) of the 10 miles of The Underline within the Miami-Dade Metrorail right-of-way site, extending from the Miami River to SW 98th Street along US-1 in Miami, Florida (the site or subject property). Miami-Dade County Parks, Recreation, and Open Spaces (MDPROS) intends to develop the subject property into a linear park, urban trail, and living art destination. The Character Zones of The Underline are proposed for extensive recreational uses including basketball courts, skating fields, soccer field, butterfly gardens, seating areas and exercise gymnasium. A Limited Phase I ESA dated May 23, 2016, prepared by Amec Foster Wheeler, was submitted to the Miami-Dade County Department of Environmental Resources Management (DERM). The Supplemental Phase I ESA was performed to address DERM’s July 25, 2016 and September 28, 2016 memoranda in response to the Limited Phase I ESA. DERM’s memoranda requested additional information and a sampling & analysis plan for a Phase II ESA of The Underline. Copies of the DERM memoranda are included in Appendix A.

Our Supplemental Phase I ESA services were conducted in accordance with industry- accepted standards. The services include a review of topographic, fire insurance maps, aerial photographs and historical use documents for sections of The Underline. The sections of The Underline reviewed are proposed for extensive use recreational purposes. MSA and Amec Foster Wheeler’s qualifications and limitations for this Supplemental Phase I ESA are provided under the appropriate sections of this report.

1.1 PURPOSE

The purpose of the Supplemental Phase I ESA is to further document current and historical use information on sections (Character Zones) of the subject property and in the site vicinity (within 500 feet laterally of the site) to identify actual and potential environmental concerns relative to the site. The report is intended to assist MDPROS with the evaluation of the risk of adverse environmental impact to the subject property. In addition, the report provides information for the design of a Phase II sampling and analysis program included in the report for review by MDPROS and DERM as the next step in the environmental evaluation of the site.

The goal of the Supplemental Phase I ESA process is to identify additional recognized environmental conditions (RECs). The term REC means the presence or likely presence of any hazardous substances or petroleum products in, on, or at a site: (1) due to any release to the environment, (2) under conditions indicative of a release to the environment, or (3) under conditions that pose a material threat of a future release to the environment. De minimis conditions are not RECs. A de minimis condition generally does not present a

1-3 The Underline, Miami FL - Supplemental Phase I & Sampling Plan Amec Foster Wheeler Project Number 6783-16-2797 February 20, 2017

threat to human health or the environment and generally would not be the subject of an enforcement action if brought to the attention of appropriate governmental agencies.

Separate and distinct from a REC are two other types of conditions that may be noted in a Phase I ESA: a controlled REC (CREC) or historical REC (HREC).

A CREC is a REC resulting from a past release of hazardous substances or petroleum products that has been addressed to the current satisfaction of the applicable regulatory authority (for example, as evidenced by a no further action [NFA] letter or the equivalent, or meeting risk-based criteria established by the regulatory authority), with hazardous substances or petroleum products allowed to remain in place subject to the implementation of required controls, such as site use restrictions, activity and use limitations (AULs), institutional controls, or engineering controls.

An HREC is a REC from a past release of any hazardous substances or petroleum products that has occurred in connection with the site and has been addressed to the satisfaction of the applicable regulatory authority (using current criteria) or meets the unrestricted residential use criteria established by the regulatory authority and applicable at the time of this Supplemental Phase I ESA without subjecting the site to any required controls.

1.2 DETAILED SCOPE OF SERVICES

A Supplementary Phase I was conducted at the request of DERM. Based on the linear nature of the site, the Supplemental ESA scope is as requested by DERM and was designed to adhere to the applicable aspects of Guidance Document E-1527-13 - ASTM Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process. The deviations from the ASTM standard are designed to better serve the intended purpose of the report – to provide the basis for the design of a Phase II sampling and analysis plan for the site. Because there is no proposed property sale or purchase transaction, the elements of the ASTM guidance that are designed only to provide protection for property purchasers, were not included. The exclusion of the property transaction aspects of the ASTM standard were discussed during separate planning meetings and telephone conversations with DERM and MDPROS. DERM agreed with the modification of the study area to address the linear nature of the property and determined that the exclusion of property transaction aspects of the ASTM Standard should be discussed with MDPROS. MDPROS agreed that, because there would be no property transaction, it would not be necessary to adhere to the property transaction aspects of the ASTM Standard. MDPROS also indicated that groundwater would not be used for irrigation or any other purpose in their planned used for the property. As such, potential groundwater impacts to the site are not a significant element of this ESA.

3.0 HISTORICAL RECORDS REVIEW

As requested in DERM’s July 2016 and September 2016 memoranda, Amec Foster Wheeler staff reviewed topographic, fire insurance maps, aerial photographs and historical use documents for sections of The Underline provided by EDR in January 2016 under Inquiry Number 4835529, to review the history of the previous uses of the surrounding areas in order to help further identify the likelihood of past uses that could have led to RECs in connection with the site. Due to the length of the 10-Mile Corridor Park and the extensive review that would be required, Amec Foster Wheeler requested in a correspondence dated September 26, 2016, that the review of historical fire insurance maps, historical aerials, historical topographic maps and historical use information be limited to twenty sections of the Park designated as Character Zones that are proposed for extensive recreational uses including basketball courts, skating fields, soccer field, butterfly gardens, seating areas and exercise gymnasium. Figures 1 to 12 illustrate the locations of the Character Zones. The DERM approved Amec Foster Wheeler’s request in their correspondence dated September 28, 2016. Amec Foster Wheeler grouped the twenty Character Zones into five areas for the historical records review. The five Character Zone areas are: Brickell to Vizcaya, Vizcaya to North Coconut Grove, North Coconut Grove to Douglas, Coral Gables to South Miami and South Miami to Dadeland North.

To further assess the land use history for the site and adjacent properties, Amec Foster Wheeler reviewed the following sources:

 Historic aerial photographs;  Historical USGS topographical maps;  Sanborn® Maps and;  EDR’s Local Street Directory (City Directory).

Service stations at 3498 S Dixie Hwy, Miami (currently 7 Eleven # 37601) and 3198 S Dixie Hwy (currently Grove Automotive) were identified and are listed in previous sections.

3.4 LOCAL STREET DIRECTORY

Amec Foster Wheeler obtained City Directory Abstracts from EDR from 1923 to 2013 for the five Character Zone areas: Brickell to Vizcaya, Vizcaya to North Coconut Grove, North Coconut Grove to Douglas, Coral Gables to South Miami and South Miami to Dadeland North and surrounding properties. A complete list of the results is included in EDR’s City Directory Abstract included in Appendix B. Amec Foster Wheeler reviewed the report as a screening tool to assist in evaluating potential contaminant sources resulting from past activities on or near the site. Due to the extensive list of residences and companies presented on the city directory please refer to Appendix B for the complete list of results. The Site was not in the City Directory Abstracts from 1923 to 2013. The adjoining properties are listed from 1923 to 2013 as commercial and residential properties. Amec Foster Wheeler’s review of the local street directory records did not identify historical usage of the Site that would be considered a REC in connection with the site.

3.5 HISTORICAL USE INFORMATION ON ADJOINING PROPERTIES

Amec Foster Wheeler staff obtained historical use information on several adjoining properties in the process of researching the site, as described in the preceding sections. Based on our review, historical records identified some adjacent sites that have the likelihood of past uses that cause them to be considered as RECs in connection with the site. The identified historical sites have been listed in the previous sections.

4.0 FINDINGS

Amec Foster Wheeler staff has performed this Supplemental Phase I ESA for the site identified as The Underline within the Metrorail right-of-way extending from the SW 98th Street northeast to the Brickell Station at the northern end in Miami-Dade County, Florida.

The following RECs and other environmental concerns were identified during the completion of this Limited Phase I ESA (May 2016) and this Supplemental Phase I ESA:

 An area located approximately 570 feet north of the Vizcaya Station and approximately 70 feet to the east of the underline of the rail was observed to the filled with trash, debris or other solid waste during the site reconnaissance (May 2016 Limited Phase 1 ESA) and is considered a REC.

 Twenty-three adjacent and surrounding properties along the site within 500 feet on each side of the site with documented contaminants are considered RECs. Figure 1 to Figure 12 illustrates the adjacent and surrounding properties considered as RECs.

4-1 The Underline, Miami FL - Supplemental Phase I & Sampling Plan Amec Foster Wheeler Project Number 6783-16-2797 February 20, 2017

5.0 OPINION

Based on the opinion of the environmental professional, the site may be impacted by contamination from adjacent and surrounding properties and as requested by DERM, a Phase II ESA should be performed for further evaluation. It should be noted that the groundwater contamination concerns associated with the RECs may not be relevant for the proposed use of the subject property since no groundwater use or likely groundwater contact is anticipated. Soil vapor that may emanate from the likely concentrations of groundwater contaminants to open surface areas would likely be insignificant.

5-1 The Underline, Miami FL - Supplemental Phase I & Sampling Plan Amec Foster Wheeler Project Number 6783-16-2797 February 20, 2017

6.0 SAMPLING AND ANALYSIS PLAN

Based on the location of the listed RECs identified during the Limited Phase I ESA and Supplemental Phase I ESA, sections of the site may be impacted by contamination from adjacent and surrounding properties. As requested by DERM, Amec Foster Wheeler has developed a sampling and analysis plan based on the history of the Site and the identified RECs. As stated in previous sections groundwater contamination concerns associated with the RECs may not be relevant for the proposed use of the subject property since no groundwater use or likely groundwater contact is anticipated. As such the sampling and analysis plan does not include groundwater assessment.

The scope of work for screening for potential soil contamination includes the following tasks:

 Install one soil boring to a maximum depth of 2 feet below ground surface (bgs) at locations along the Site that are in the vicinity (within 500’) of dry cleaner contaminated sites. Collect two soil samples from the 0-6” and 6”-2’ bgs for laboratory analysis of VOCs by EPA Method 8260B, PAHs by EPA Method 8270C, TRPH by FL PRO, and 8 RCRA metals by EPA Method 6020B.  Install one soil boring to a maximum depth of 2 feet bgs at locations along the Site that are in the vicinity (immediately adjacent) of petroleum contaminated sites. Collect two soil samples from the 0-6” and 6”-2’ bgs for laboratory analysis of BTEX/MTBE by EPA Method 8260B, PAHs by EPA Method 8270C, TRPH by FL PRO, and 8 RCRA metals by EPA Method 6020B.  Install one soil boring to a maximum depth of 2 feet bgs immediately adjacent to the former rail line or the current Metrorail tracks at approximately 2,000 feet intervals, along the Metrorail. The sampling locations have been adjusted to be more concentrated on the proposed character zones due to the proposed greater use and potential for exposure. Collect two soil samples from the 0-6” and 6”-2’ bgs for laboratory analysis of PAHs by EPA Method 8270 and Pb EPA Method 6020B.  An area located approximately 570 feet north of the Vizcaya Station and approximately 70 feet to the east of the underline of the rail was observed to the filled with trash, debris or other solid waste during the site reconnaissance (May 2016 Limited Phase I ESA). Install one soil boring to a maximum depth of 2 feet bgs in the vicinity of the solid waste area. Collect two soil samples from the 0-6” and 6”-2’ bgs for laboratory analysis of VOCs by EPA Method 8260B, PAHs by EPA Method 8270C, TRPH by FL PRO, and 8 RCRA metals by EPA Method 6020B.  Soil types will be classified using the Unified Soil Classification System.

6-1 The Underline, Miami FL - Supplemental Phase I & Sampling Plan Amec Foster Wheeler Project Number 6783-16-2797 February 20, 2017

As requested in DERM’s July 2016 memo, Amec Foster Wheeler researched the National Pipeline Mapping System for the location of the Everglades Pipeline owned by Buckeye Partners LP to determine the proximity and potential impact of the Everglades Pipeline to the Site. In addition, Amec Foster Wheeler reviewed Buckeye Partners’ system map for pipelines in Miami Dade County (Figure 13). The National Mapping Pipeline System and Buckeye Partners’ system map did not identify any pipeline conveying hazardous liquid in the vicinity of the Site. As such, sampling and analysis to evaluate the impact of the Everglades Pipeline is not required. A figure illustrating the location of a pipeline conveying hazardous liquid from the National Mapping Pipeline System and the Site is included as Figure 14.

Figure 1 through 12 illustrates the locations of the proposed soil borings.

7.0 CONCLUSIONS

Amec Foster Wheeler staff has performed a Supplemental Phase I ESA for the sections (Character Zones) of the 10-mile long site identified as The Underline within the Metrorail right-of-way extending from the SW 98th Street northeast to the Brickell Station in Miami- Dade County, Florida. This assessment has revealed evidence of recognized environmental conditions in connection with the site. The RECs are primarily associated with contaminated groundwater, which may not be relevant based on the anticipated non groundwater use of the subject site. The listed RECs were used in the design of a Phase II sampling and analysis plan (included in this report) for the site.

Should additional surface, subsurface, chemical, or other data become available after the date of issue of this report, the findings, conclusions, and recommendations contained herein may need to be modified.

Hi Becky

Below, please find information requested per your email:

1. No construction activities that may provide exposure pathways to construction workers for potential soil or groundwater impacts (if any are present) are plannecl for the areas outside of the character zones. In addition, no extensive recreational activities that may expose the public to potential soil or groundwater impact (if any are present) are planned for the non-character zone areas. The non-character zone areas are proposed to be passive bike and walking paths. 2. At this time the locations and extents of the character zones are not intended to change and are planned to remain as currently proposed. No groundwater use or contact 1Nith groundwater is necessary or proposed anywhere on the project. If any irrigation is required for character zone landscaping, municipal water supplies will used.

Best regards,

Good Morning,

DERM is reviewing the referenced submittal dated September 16, 2016 and requires the following information prior to completing our review:

1. Please provide details of those areas not within the character zones that substantiate your request not to perform the historical analyses outside of the character zones. What is the specific design plan for the areas not within a zone (i.e., passive bike/walking path versus any other type of activity)?

2. Regarding the planning process, provide details on whether the location and extent of the character zones are subject to change or whether the zones will remain as currently proposed.

If you have any questions, Please let me know.
