Benson Quarry
Groundwater and Surface Water
Monitoring Report
Johnston County, North Carolina
1.0 Project Description
Martin Marietta Materials, Inc. (Martin) is expanding the existing Benson Quarry facility, located
southeast of the intersection of Raleigh Road (SR 1330) and Camelia Road (SR 1354) in Johnston
County, North Carolina (Figure 1). The proposed quarry expansion activities involve unavoidable
impacts to jurisdictional wetlands that have been authorized under Clean Water Act Section 404 and
401.
The project includes diversion of hydrology in the Stony Fork wetland system on the property. This
diversion occurs upstream of the proposed direct wetland impacts. The portion of this wetland system
between the diversion channel and the direct impact area (Figure 1) may be subject to secondary impacts
as a result of this hydrologic alteration. Potential secondary impacts may include changes to natural
hydrology which may affect the quality of the wetlands in this area through changes in the number,
frequency, duration, and level of flooding events, changes in groundwater levels and shallow
groundwater recharge, or other changes in hydroperiod.
The purpose of this monitoring report is to provide the results for monitoring hydrology levels and
vegetation in this area of interest. Automatic monitoring gauges were installed on August 20, 2016;
these gauges collected groundwater elevation data daily for the duration of the 2017 growing season.
This monitoring process is a condition outlined in both the U.S. Army Corps of Engineers (SAW -2014-
00845) and N.C. Division of Water Resources (95-0153) permit authorizations.
2.0 Existing Conditions
The portions of the Stony Fork wetland system upstream of the quarry expansion currently exhibit the
same natural characteristics that were present during the jurisdictional determination and permitting
processes for this project. Construction of the diversion channel in the upland has been completed and
a portion of the hydrology in the Stony Fork wetland system is being actively diverted. Construction to
connect the diversion channel to the wetland system was completed on May 5, 2017.
3.0 Monitoring Specifications
The site was monitored for two primary wetland parameters: hydrology and vegetation. The hydrologic
success criterion requires the soil to be ponded, flooded, or saturated within 12 inches of the surface for
a least 12.5 % of the growing season during years with normal precipitation. The growing season extends
from March 20th to November 181h in Johnston County (243 days).
Monitoring gauges were installed to a depth of 20 inches at all seven (7) locations. Monitoring gauges
are manufactured by Remote Data Systems (Ecotone WM model). These are automatic gauges that are
programmed to collect data at the same time daily.
Four (4) monitoring gauges (Gauges 1-4 on Figure 1) were installed within the portion of the wetland
system where secondary impacts may occur in order to document the wetland's hydrologic response to
the construction of the diversion channel.

Three (3) monitoring gauges (Gauges 5-7 on Figure 1) were installed within the portion of the wetland
system upstream of the diversion channel in order to provide reference condition hydrologic data.
Rainfall data was collected by a previously installed rain gauge on the Benson Quarry property. Figure
1 depicts the approximate locations of the monitoring gauges within the wetland area. The rainfall totals
are provided in Table 1.
Photographs were taken monthly adjacent to the monitoring well locations to document any changes in
vegetation that may occur as a result of altered hydrology. The photograph origin locations were marked
with a wooden stake in the field.
Hydrologic data collection occurred monthly during the growing season. The data presented in this
report represents the 2017 growing season. Ground water and surface water data was collected on all
244 days in growing season.

4.0 Findings
During the 2017 monitoring period, all 7 monitoring gauges met the hydrologic success criterion that
requires the soil to ponded, flooded, or saturated for at least 12% of the growing season. All results are
also depicted in graphs located in Appendix B.

* Reference gauge upstream of diversion channel
Gauges 1 and 2, located at the downstream end of the area of interest, exhibited longer hydroperiods
than gauges in the reference location.
Of the 1708 possible data samples, 42 of the samples (2%) were lost or not collected due to gauge
malfunctions. This loss of data did not affect the determination of hydrologic success for any of the
wells.
Photographs to record vegetative characteristics were taken monthly at each well and are provided in
Appendix C. Based on visual examination of photographic evidence, no significant changes in the
wetland vegetative communities has occurred as a result of this project as of the end of the 2017 growing
season.
Based on the hydrologic success of gauges 1-4 (downstream of diversion channel connection) and the
absence of changes to vegetation with the Stony Fork wetland system, it was determined that
jurisdictional wetland criteria still exist within the area of interest.
5.0 Future Monitoring
Monitoring will resume during the official 2018 growing season. The 2018 Groundwater and Surface
Water Monitoring Report will be completed in December 2018.
