Ardaman Project No. 13-33-4533 11-SEPT-2013 Hole Montes 6200 Whiskey Creek Drive Fort Myers, FL 33919 Attention: Mr. Bob Murray, P.E. SUBJECT: Subsurface Soil Exploration Tice Street Water Main Loop Fort Myers, Lee County, Florida Gentlemen: As requested and authorized by Hole Montes, Ardaman & Associates, Inc. (Ardaman) has completed the subsurface soil exploration program for the subject project. The purposes of this program were to evaluate the general subsurface conditions at the project site and discuss our findings. This report documents our findings and conclusions. It has been prepared for the exclusive use of Hole Montes and their consultants 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 Standard Penetration Test (SPT) borings to 50 feet and two SPT boring to 25

feet to determine the nature and condition of the subsurface soils at the location of the directional bore under I-75 and the drainage ditch crossing Country Lakes Drive, and 17 hand auger borings to a maximum depth of 6 feet to define subsurface conditions along the route of the proposed water main within the south right-of-way of Tice Street and west right-of-way of Country Lakes Drive.

2. Reviewing each soil sample obtained in our field testing program by a geotechnical engineer in

our laboratory for further identification and assignment of laboratory tests.

3. Performing the appropriate laboratory tests on selected samples. 4. Analyzing the existing soil conditions with respect to the proposed construction. 5. Preparing this report to document the results of our field exploration and laboratory testing

programs.

SITE LOCATION AND PROJECT DESCRIPTION The Tice Street Water Main Loop project limits are from the Tice Street and Detar Way intersection eastward along the south right-of-way of Tice Street to Country Lakes Drive, then southward along the west right-of-way of Country Lakes Drive to Longleaf Drive. New 12-inch ductile iron pipe (D.I.P.) water main is proposed along Tice Street, and 10-inch D.I.P. water main along Country Lakes Drive. Under I-75, 14-inch HDPE pipe within 24-inch HDPE casing will be installed by directional bore. Under the Country Lakes Drive drainage ditch, 12-inch HDPE pipe will be installed. Aerial photographs of the water main alignments with boring locations are presented as Figures 1 and 1A in Appendix 1.

REVIEW OF SOIL SURVEY MAPS

The United States Department of Agriculture Natural Resources Conservation Services Soil Survey of Lee County, Florida (1984) was reviewed for major shallow soil types within the project limits. The Soil Survey identified four major soil map units described as follows:

Wabasso sand, limestone substratum (42). This soil map unit occurs within the Tice Street right-of-way from the project beginning near Detar Way to about 500 feet eastward. This soil type is described as fine sand (SP, SP-SM) and silty fine sand (SM) to a depth of 3 feet underlain by silty clayey sand (SM, SC-SM, SC). Weathered bedrock is at a depth of 4 feet. Oldsmar sand (33). This soil map unit occurs in the Tice Street right-of-way from about Lexington Avenue to the start of the I-75 east bridge approach embankment. This soil type is described as fine sand (SP-SP-SM) and slightly silty fine sand (SM) to a depth of 4 feet underlain by silty clayey sand (SM, SC-SM, SC) to 5 feet. Slightly silty fine sand (SP-SM, SM) is encountered again below 5 feet.



Hallandale fine sand (6). This soil map unit occurs within the Tice Street right-of-way from the start of the I-75 east bridge approach embankment to Country Lakes Drive. This soil is described as fine sand (SP, SP-SM) to a depth of 12 inches underlain by soft weathered limestone bedrock that has solution holes extending to a depth of 25 inches. Boca fine sand (13). This soil map unit occurs within the Country Lakes Drive right-of-way from Tice Street to the project end at Longleaf Drive. This soil is described as fine sands (SP, SP-SM) to a depth of about 2 feet underlain by 0.5 feet of clayey sand (SC). At a depth of 2.5 feet is a layer of soft fractured limestone.

FIELD EXPLORATION PROGRAM Our field exploration consisted of performing two Standard Penetration Test (SPT) borings labeled SPT-5 and 6 at the directional bore location under I-75, two SPT boring labeled SPT-15 and 16 and 17 hand auger borings labeled A-1 through A-5, A-7 through A-14 and A-16 through A19 on approximately 300-foot centers along the proposed water main routes. The SPT borings located within the I-75 right-of-way were drilled to a depth of 50 feet below the existing ground surface, and the SPT borings for the drainage ditch crossing on Country Lakes Drive were drilled to 25 feet. The SPT borings were conducted using methods consistent with ASTM D-1586. A hand-held bucket auger was used to advance each hand auger boring to a depth of 6 feet unless refusal on rock was encountered. The equipment and procedures used in the SPT and hand auger borings are described in detail in Appendix 3. The approximate locations of the four SPT borings and 17 hand auger borings are shown on the Boring Location Plan presented as Figures 1 and 1A included in Appendix 1. The GPS coordinates of each boring are shown on each boring log.

GENERAL SUBSURFACE CONDITIONS The general subsurface conditions encountered during the field exploration are shown on the attached soil boring logs in Appendix I. 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. The two SPT borings SPT-6 and 7 at the directional bore under I-75 disclosed similar subsurface conditions described as follows. Depth From To Soil Description Ground Surface 22' Loose to medium dense fine sands (SP) and slightly silty fine sands (SP- SM) with trace amounts of shell fragments. 22' 27' Soft calcareous very clayey fine sands (SC). 27' 42' Medium dense to dense fine sands (SP) and slightly silty fine sands (SP- SM) with shell fragments. 42' (50') TERM Medium stiff clayey sands (SC) and sandy clays (CL) with medium plasticity. The two SPT borings SPT-15 and 16 for the crossing under the Country Lakes Drive drainage ditch also disclosed similar subsurface conditions described as follows. Depth From To Soil Description Ground Surface 4' Loose to medium dense fine sands (SP). 4' 5' Medium stiff clayey sand. (SC). 5' 13' Loose fine sands (SP) with trace amounts of shell fragments. 13' 23' Loose calcareous slightly silty fine sands (SM) with trace amounts of gravel-size shell and limerock fragments. 23' (25') TERM Loose silty clayey sands (SC-SM), with trace to some amounts of gravel- size shell and limerock fragments.



The 17 hand auger borings encountered mostly fine sands (SP) from the ground surface to the 6-foot depth explored. Occasionally a thin stratum of silty clayey sand (SC-SM or A-2-6) or clayey sand (SC or A-2-4) was encountered in the 3-1/2 to 4-1/2 foot depth range. The hand auger borings along Country Lakes Road encountered a gravelly fine sand (SP or A-3) below a depth of about 4 feet with the gravel composed of shell and limerock fragments. It is possible that cobble and boulder-size pieces of limerock and cemented sands occur within this stratum. No rock was encountered in the borings except in boring A-10 where refusal was encountered at a depth of 2.5 feet. Additional auger borings A-10A and 10B were drilled 50 feet west and east, respectively, to determine the extent of the rock. Boring A-10A did not encounter rock within the 6-foot depth explored. Boring A-10B encountered rock at a depth of 1-foot. This indicates that shallow caprock should be expected within this segment. Groundwater was encountered within 1-foot of the ground surface in the auger borings performed along Tice Street on the date of drilling (9/4/13). Along Country Lakes Drive, groundwater was typically encountered in the 3 to 3.5-foot depth range on the date of drilling (8/29/13). The groundwater depths shown on the boring logs represent the ground water surface encountered on the dates shown. 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. Laboratory testing was performed on selected samples as deemed necessary to aid in soil classification and to further define the engineering properties of the soils. The laboratory tests included Natural Moisture Content, Percent Finer that the U.S. No. 200 Sieve (percent silt and clay) and Sieve Analysis. The test results are presented on the attached soil boring logs at the depths from which the samples were recovered. The boring logs are included in Appendix 1 of this report. The results of sieve analysis are presented on grain-size distribution sheets included in Appendix 2. 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. The soils recovered from the borings were also classified in accordance with AASHTO M-145–Recommended Procedure for the Classification of Soils and Soil-Aggregate Mixtures for Highway Construction Purposes.

DISCUSSION

The hand auger borings encountered mostly fine sands (SP or A-3) occasionally underlain by thin layers of silty clayey sands (SC-SM or A-2-4) and clayey sands (SC or A-2-6) from the ground surface to the 6-foot depth explored. Only auger borings A-10 and A-10B terminated on rock at depths of 2.5 feet and 1-foot, respectively. The Soil Survey indicates that weathered bedrock occurs at a depth of 4 feet within the Wabasso sand, limestone substratum (42) soil map unit identified at the project beginning near Detar Way. The soil survey also indicates that soft weathered limestone bedrock occurs at a depth of 12 inches within the Hallandale fine sand (6) soil map unit identified along Tice Street east of the I-75 bridge. It also indicates that soft fractured limestone occurs at a depth of 2.5 feet within the Boca fine sand (13) soil map unit identified along Country Lakes Drive. Based upon the auger borings, limestone rock should be expected along some segments of Tice Street east of I-75 bridge. Also, cobble and boulder-size pieces of limerock and cemented soils may occur within the gravelly sand stratum encountered below a depth of 4 feet in the auger borings along Country Lakes Drive. Typically, heavy excavators can remove soft limestone and boulders; however, dynamic methods using hydraulic hammers or hoes will be needed to remove hard limestone or large boulders where they occur. Use of excavated rock as a fill material will require further processing (crushing and screening) to reduce particle size to mostly sand and gravel size. The fine sands (SP or A-3 soils) encountered in the test borings are suitable for use as backfill materials and suitable for pipe bedding. However, the pipe should be bedded in gravel such as FDOT No. 89 or 57 Stone if rock occurs within 6 inches of the pipe bottom, or unsuitable soil types are encountered at pipe invert such as silty clayey sands (SC-SM or A-2-4) or clayey sands (SC or A-2-6).
