Dear Mr. Dodd,

ECS Southeast, LLC (ECS) has completed the limited subsurface exploration, laboratory testing, and

geotechnical engineering considerations for the above-referenced project. Our services were performed

in general accordance with our agreed to scope of work. This report presents our understanding of the

geotechnical aspects of the project along with the results of the field exploration and laboratory testing

conducted, and our design and construction recommendations.

It has been our pleasure to be of service to you during the design phase of this project. We would

appreciate the opportunity to remain involved during the continuation of the design and construction

phase to confirm subsurface conditions assumed for this report. Should you have any questions

concerning the information contained in this report, or if we can be of further assistance to you, please

contact us at (704) 525-5152.

Respectfully submitted,

1.0 INTRODUCTION

The purpose of this study was to provide subsurface exploration and geotechnical considerations for the

proposed improvements at the Forestview High School athletic field and track located in Gastonia, Gaston

County, North Carolina. The recommendations developed for this report are based on the project

information supplied by the Client. Our services were provided in accordance with ECS Proposal No.

08:30924P dated October 20, 2025, and includes the Terms and Conditions of Service outlined within the

agreement.

This report contains the procedures and results of our subsurface exploration and laboratory testing

programs, review of existing site conditions, and general considerations regarding the geotechnical

aspects of the project. The report includes the following items.

• Information on current site conditions, including geologic information and special site features.

• Description of the field exploration and laboratory tests performed.

• Final logs of the soil borings and records of the field exploration and laboratory tests performed.

• Measurement of the surficial materials at each boring location.

• Evaluation of the on-site soil characteristics encountered in the hand auger borings with respect to

the suitability of the on-site materials for reuse as Engineered Fill.

• General recommendations for compaction requirements for fill and backfill areas.

• General recommendations regarding site preparation and construction observations and testing.

2.0 PROJECT INFORMATION

2.1 PROJECT LOCATION/CURRENT SITE USE/PAST SITE USE

The project site is located at 5545 Union Road in Gastonia, Gaston County, North Carolina as shown on

the figure below and included on the Site Location Diagram in Appendix A. According to Mecklenburg

County GIS, the site is a portion of the parcel identified as Gaston County Parcels ID Number (PIN) 3562-

28-6984.

Based on our site reconnaissance, the site is currently developed with an athletic field and track,

associated ancillary structures, and drive areas. The site is located within the northeastern portion of the

Forestview High School Campus and surrounded by additional athletic fields and parking areas. Based on

available Gaston County GIS topographic information, existing site grade elevations range from

approximately 752 to 754 feet.

Based on a review of available historic imagery, as early as 1956, it appears that the site was undeveloped

and consisted primarily of wooded land. By 1998, the Forestview High School campus had been

constructed. The site has remained in a generally similar condition since that time. The previous use of

discussion is not considered a comprehensive or in-depth of the site history, rather a quick overview of

available aerial imagery.

2.2 PROPOSED CONSTRUCTION

The site is currently an active high school athletic field and track. Based on our correspondence with you,

we understand that the existing track will be removed and replaced, and a new synthetic turf field system

will be installed. No additional information has been provided to us.

3.0 FIELD EXPLORATION AND LABORATORY TESTING

Our exploration procedures are explained in greater detail in Appendix B including the insert titled

Subsurface Exploration Procedure. Our scope of work included performing four (4) asphalt cores within

the existing track pavement and three (3) hand auger borings coupled with WildcatTM Dynamic Cone

Penetrometer (WDCP) tests to depths of approximately 3 feet below existing grades within the athletic

field area. The borings were located using GPS technology and existing site features as reference and their

approximate locations are shown on the Exploration Location Diagram in Appendix A. The topographic

data and elevations noted on the Boring Logs, Subsurface Cross Section, and referenced in this report

were estimated from Gaston County GIS topographic information and should be considered preliminary

and approximate.

3.1 SUBSURFACE CHARACTERIZATION

The site is located in the Piedmont Physiographic Province of North Carolina. The native soils in the

Piedmont Province consist mainly of residuum with underlying saprolites weathered from the parent

bedrock, which can be found in both weathered and unweathered states. In a mature weathering profile

of the Piedmont Province, the soils are generally found to be finer grained at the surface where more

extensive weathering has occurred. The particle size of the soils generally becomes more granular with

increasing depth and gradually changes first to weathered and finally to unweathered parent bedrock.

The natural geology within the site has been modified in the past by grading, disturbance of near-surface

soils, and/or placement of fill materials. The quality of man-made fills can vary significantly, and it is

difficult to assess the engineering properties of existing fills. Furthermore, there is no specific correlation

between WDCP penetration test values and the degree of compaction of existing fill soils; however, a

qualitative assessment of existing fills can sometimes be made based on the penetration values obtained

and observations of the materials sampled in the borings.

The following sections provide generalized characterizations of the subsurface materials. Please refer to

the Generalized Subsurface Cross Section in Appendix A and Hand Auger Logs in Appendix B for more

detailed information.
