SUBJECT: Subsurface Soil Exploration 42-inch Force Main Replacement Chiquita Boulevard S and SW 34 th Street Cape Coral, Lee County, Florida Dear Tyler: As requested and authorized by Tetra Tech, Ardaman & Associates, Inc. (Ardaman) has completed the subsurface soil exploration program for the subject project. The purpose of this program was to evaluate the general subsurface conditions at the site proposed for a jack and bore or directional drill for a 42-inch force main. This report documents our findings and conclusions. It has been prepared for the exclusive use of Tetra Tech for specific application to the subject project in accordance with generally accepted geotechnical engineering practices. No other warranty, expressed or implied, is made. SCOPE The scope of our services was limited to the following items: 1. Conducting two (2) Standard Penetration Test (SPT) borings to determine the nature and condition of the subsurface soils. 2. Reviewing each soil sample obtained in our field exploration program by a geotechnical engineer in our laboratory for soil classification purposes. 3. Performing the appropriate laboratory tests on selected samples, if required. 9970 Bavaria Road, Fort Myers, Florida 33913 Phone (239) 768-6600 FAX (239) 768-0409 Florida: Bartow, Fort Myers, Miami, Orlando, Port St. Lucie, Sarasota, Tallahassee, Tampa, West Palm Beach Louisiana: Alexandria, Baton Rouge, Monroe, New Orleans, Shreveport

Preparing this report to document the results of our field exploration and laboratory testing programs. SITE LOCATION AND PROJECT DESCRIPTION The project area is located on Chiquita Boulevard S. just south of SW 34 th Street in Cape Coral, Lee County, Florida. A Site Location Map is presented as Figure 1. We understand that a jack and bore or directional drill is planned under Chiquita Boulevard S. just south of SW 34 th Street as part of the 42-inch force main replacement project. The purpose of the subsurface soil exploration was to define the subsurface conditions at the specific directional drill location. FIELD EXPLORATION PROGRAM Our field exploration consisted of performing two (2) Standard Penetration Test (SPT) borings. The SPT borings were drilled to a depth of 20 feet below the existing ground surface. The SPT borings were conducted using methods consistent with ASTM D-1586. The equipment and procedures used in the SPT borings are described in detail in the Appendix. The locations of the borings are shown on the attached Boring Location Plan (Figure 2). They were located by measurement from the site features shown on an aerial photograph of the site obtained from the Lee County Property Appraiser s website. Therefore, the locations indicated should be considered accurate only to the degree implied by the method of measurement used. The GPS coordinates of each boring location from a hand-held device are provided on each boring log. GENERAL SUBSURFACE CONDITIONS The general subsurface conditions encountered during the field exploration are shown on the attached soil boring logs. Soil stratification is based on examination of recovered soil samples and interpretation of the field boring logs. The stratification lines represent the approximate boundaries between the soil types, the actual transitions may be gradual. Ardaman & Associates, Inc.
Report of Subsurface Soil Exploration for 22-APR-2016 42-inch Force Main Replacement Project No. 16-33-4532 Cape Coral, Lee Co., FL Page No. 3 A generalization of subsurface soil conditions encountered in the boring is described below. Depth From To Soil Description Ground Surface 2.5' - 3' Medium dense fine sands (SP). 2.5' - 3' 4' Boring SPT-1 encountered a medium dense clayey sand (SC). Boring SPT-2 encountered hard caprock. 4' 17' Loose to medium dense fine sands (SP) with varying amounts of gravel-size limerock and shell fragments. 17' TERM Medium dense calcareous clayey fine sands (SC). Groundwater was encountered in the boreholes at 5 feet below the existing ground surface at the time of our field exploration (20-APR-2016). groundwater surface encountered on the date shown. The groundwater depths shown on the boring logs represent the Fluctuations in groundwater level should be anticipated throughout the year due to seasonal variations in rainfall, and other factors. LABORATORY TESTING PROGRAM Representative soil samples obtained during our field sampling operation were packaged and transferred to our office and, thereafter, examined by a geotechnical engineer to obtain more accurate descriptions of the existing soil strata. The soil descriptions shown on the logs are based upon visual-manual procedures in accordance with local practice. Soil classification is in general accordance with the Unified Soil Classification System (ASTM D-2487) and is also based on visual-manual procedures. GENERAL COMMENTS While the borings are representative of subsurface conditions at their respective locations and for their respective vertical reaches, local variations characteristic of the subsurface materials of the region are anticipated and may be encountered. The boring logs and related information are based on the driller's logs and visual examination of selected sample in the laboratory. The delineation between soil types shown on the logs is approximate and the description represents our interpretation of subsurface conditions at the designated boring locations and on the particular date drilled.
