1.0 INTRODUCTION

This report summarizes the results of the geotechnical investigation performed by CHA for the

proposed roundabout at the Shelburne Road and Locust Street intersection in Burlington,

Vermont by the Vermont Agency of Transportation (VTrans). The project location is shown on

the Site Location Map included in Appendix A as Figure 1.

The objective of this investigation was to provide subsurface data in the general areas of the

proposed utility work associated with the roundabout design.


2.0 PROJECT AND SITE DESCRIPTION

We understand that the Vermont Agency of Transportation (VTrans) is planning to construct a

roundabout at the Shelburne Road and Locust Street intersection in the City of Burlington,

Vermont. As part of the construction, utilities will be relocated in the area.

The project site is approximately 1,800 linear feet and encompasses approximately 650 feet

south and 400 feet north on Shelburne Road, approximately 200 feet north on South Willard

Road, approximately 150 feet east on Ledge Street, and approximately 400 feet west on Locust

street all from the existing roundabout intersection at the project center. The existing roads are

lined with residential homes, yards, and occasional trees and the roadways experience heavy

traffic during the day. Bedrock outcrops were noted in several locations off of South Willard

Street and Shelburne Road.


3.0 SUBSURFACE INVESTIGATION

Thirty five auger probes, designated as B-301 to B-322 and B-324 to B-336, were advanced for

the subsurface investigation on September 6, October 3, and October 4, 2011. A log of

conditions encountered is included in Appendix B. This subsurface investigation was

supplemented by the borings completed by CHA in April 2011 for infiltration testing, which

were submitted to VTrans in the Geotechnical Data Report entitled “Burlington Roundabout

Infiltration Testing” and dated May 4, 2011. The boring logs from this previous investigation

are included in Appendix C. The boring and auger probe locations are shown on the Boring

Location Plan, Figures 2 through 4, included in Appendix A. Borings and auger probes noted

with an “A” were relocated from the VTrans proposed locations for utility clearance and drill rig

access purposes. The locations of these modified locations were determined by taping from

existing site features to the as-drilled boring locations. Auger probe B-323 was eliminated due to

an inability to confidently locate existing utilities within the planned probe location. The

locations of the borings should be considered accurate only to the degree implied by the method

used to determine them.

CHA retained Vermont Underground Locators, Inc. to assist with underground utility location

for sewer main lines and laterals not marked through the Dig Safe process.

CHA retained Specialty Drilling & Investigation, Inc. of Burlington, Vermont to advance the

auger probes. A CHA geotechnical engineer observed the field investigation to ensure that

proper drilling methods were used for this investigation, describe auger cuttings, and prepare

field logs documenting subsurface conditions.

The auger probes were advanced with a truck mounted drill rig (Simco 2800) using 2.25 inch

hollow stem augers. Augers were generally advanced to a depth of 15 feet or refusal, whichever

occurred first. Soil conditions were classified based upon visual observation of auger cuttings

during drilling.


4.0 SUBSURFACE CONDITIONS

4.1 Regional Geology

According to the Surficial Geologic Map of the Burlington, Vermont7.5 Minute Quadrangle

(Wright, S. et al, 2009.) the site is underlain by medium fine sand and clay rich glacial till.

According to the Geologic Map of Vermont (Doll, C. G., (1961), the bedrock within the project

area generally consists of Monkton Quartzite.

4.2 Subsurface Stratigraphy

Subsurface conditions encountered in the auger probes are detailed and described on the probe

log included in Appendix B of this report. General subsurface conditions are described below in

order of increasing depth.

Asphalt – Asphalt was encountered at the ground surface in all of the auger probes and extended

to a depth of 0.2 feet to 0.4 feet.

Concrete – Concrete was encountered below the asphalt in probes B-317 through B-319A and

was 0.5 foot to greater than 1.0 foot thick (B-317, and B-319A were terminated at auger refusal

in the concrete.

Sand – Fine to coarse sand was encountered below the asphalt in probes B-301 through B-316,

B-320 through B-332, and B-334 through B-336 and extended to depths ranging from 2.6 to 13.0

feet. The sand contained varying amounts of gravel, clay, and silt and was brown. The sand was

generally brown and the moisture content was visually classified as moist.

Glacial Till – Glacial till comprised of silty clay or clayey silt was encountered beneath the

asphalt or sand in probes B-311 through B-320, B-322 through B-329 and B-331 through B-336

and extended to boring termination. The clay and silt contained various amounts of fine to

coarse sand and fine to coarse gravel, was generally brown to gray in color and the moisture

content was visually classified as moist to wet.


Bedrock – Bedrock was inferred based upon auger refusal at depths ranging from 2.6 feet to

greater than depths explored of 15 feet.

4.3 Groundwater

Groundwater level observations were estimated from visual observation of auger cuttings

moisture content. Groundwater was observed and estimated at depths of 8.5 feet in B-320, 14.0

feet in B-322, and 13.0 feet in B-331. Local areas of perched water and seasonal factors such as

temperature and precipitation also affect groundwater levels. For this reason, long-term

groundwater levels may differ from those described in this report.


5.0 DEPTHS TO BEDROCK (AUGER REFUSAL)

The depth below the ground surface to bedrock was inferred from auger refusal during the

subsurface investigations. These depths have been summarized in the table below. A Greater

than symbol (>) indicates that bedrock was not encountered during drilling and the depth to

bedrock is greater than the depth indicated.
