Soils Properties
Soils encountered during this investigation are Roadway Embankment, Alluvial, and Residual.
Roadway Embankment soils are found at the creek crossing from -L- sta. 16+25 to 18+75. These soils
primarily consist of orange-tan, moist, loose to medium dense, silty sand (A-2-4).

Groundwater
DESCRIPTION: Construct Left Turn Lane on NC 42 at SR 2735 (Johnston Road) Groundwater measurements were taken during January of 2023 during average rainfall conditions.
Groundwater was present in borings adjacent to the creek, and it was 4.8' to 6.2' below existing grade.
SUBJECT: Geotechnical Report - Inventory
The Geotechnical Engineering Unit has completed a subsurface investigation for this project and presents
the following inventory.
Project Description
This project consists of intersection improvements and constructing a left turning lane on NC 42 at SR 2735
(Johnston Road)
A geotechnical investigation was conducted during January of 2023. Five hand-auger borings were
performed by the Geotechnical Engineering Unit. Representative soil samples were collected for visual
classification in the field and selected samples were submitted for laboratory analysis by the Materials and
Tests Unit.
The following alignment, totaling 0.187 miles, was investigated.
Line Stations

Physiography and Geology
The project is located approximately 12 miles south of the city limits of Raleigh and within the Raleigh Belt
physiographic province of North Carolina. Residual soils in this area are derived from the underlying biotite
gneiss. The topography is rolling hills. The widening project consists of a mixture of residential and
wooded areas.
