Dear Mr. Swink:
TNT Environmental, Inc. (TNT) is pleased to present this wetland delineation report for the above-
referenced project in general accordance with TNT Proposal Number 245 dated August 5, 2014. The
wetlands and Waters of the U.S. identified during this investigation for the above-referenced project
site were delineated by TNT based on the Corps of Engineers' Wetlands Delineation Manual (1987)
and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Eastern
Mountains&Piedmont Region and represent those areas that are most likely considered jurisdictional
by the U.S. Army Corps of Engineers (USACE). The delineation entails the gathering of appropriate
field data according to the applicable USACE Manuals, field flagging and mapping of approximate
wetland and stream boundaries located onsite, preparation of this final report, and a request to the
USACE for boundary confirmation and jurisdictional determination of U. S. Waters, including
wetlands, identified onsite. • •
PROJECT SITE DESCRIPTION
The Free State Run project site is approximately 7.09-acres located south of Free State Road in
Charlottesville, Virginia (Figure 1). The project site is further identified by parcel number 06200-00-
00-00800 and GPIN: 495308913478. The terrain of the project site consists moderate and steep
slopes and is within the Rivanna River drainage basin (Figure 2). The site is wooded and unimproved.
SECONDARY INFORMATION REVIEW
Secondary Information entails the background research and review of recorded data and/or mapping
associated with the project site. Resources reviewed include but are not limited to the following:

The USGS Charlottesville East quadrangle map shows elevations of approximately 450 feet above
mean sea level (MSL) in the northern portion of the site and approximately 375 feet above MSL in the
southern portions. As shown on the USGS Map,the project site drains to Town Branch, located within
the Rivanna River watershed and identified as Hydrologic Unit Code (HUC) 02080204. The NWI map
does not depict wetland features within the project site boundaries. The soil survey indicates that
the site is underlain primarily by 2C—Albemarle fine sandy loam, 21B—Culpeper fine sandy loam and
39D—Hazel loam.
FIELD INVESTIGATION & METHODOLOGY
Fieldwork was conducted during August 2014 using the Corps of Engineers' Wetlands Delineation
Manual(1987) and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual:
Eastern Mountains & Piedmont Region. The USACE Manual and associated Regional Supplement
follow three parameters for the identification of wetlands: dominance of hydrophytic vegetation,
presence of hydric soils, and hydrologic indicators. All three parameters must be present under
normal conditions for an area to be considered a jurisdictional wetland in accordance with Section
404 of the Clean Water Act. Wetlands are then further classified according to the Cowardin System
as described in Classification of Wetlands and Deepwater Habitats of the United States(1979).
The fieldwork was conducted to evaluate and characterize the soils, vegetation and hydrology, and
establish the boundaries of wetlands or Waters of the U.S. located within the area of investigation.
Wetland flags were placed in the field and sequentially numbered to provide an onsite record of the
location of wetlands and other Waters subject to the jurisdiction of state and federal agencies. The
data sheets used in this investigation are enclosed,along with the Delineation Map showing data point
locations and approximate wetland and Waters boundaries. A summary of the attached data sheets
is included below in Table 3. Additionally, a photographic log documenting site conditions
encountered is enclosed.
FINDINGS
Based on our field reconnaissance, TNT has identified and located one ephemeral seep, one ( ii
intermittent and one ephemeral stream onsite. Dominant riparian buffer vegetation is listed below
in Table 1. The main source of hydrology for these streams includes a culvert which directs flow onsite
from north of Free State Road and groundwater. The ephemeral stream also originates in the
northernportion of the site,
presumably from a perched groundwater table.

REGULATORY DISCUSSION
The USACE - Norfolk District and the Virginia Department of Environmental Quality (DEQ) have
implemented the State Programmatic General Permit (SPGP) program to streamline the permit
process and avoid duplication of agency review. For those projects impacting less than 0.1-acres of
non-tidal wetlands and less than 300 linear feet of stream bed a Nationwide permit from the USACE
can be obtained for most projects. For those projects impacting greater than 0.1-acres of wetlands
and 300-1,500 linear feet of stream bed,a General Permit can be obtained from DEQ. All SPGP permit
applications are reviewed by the USACE but the permit authorization comes solely from DEQ.
Notification of potential impacts should be filed with DEQ by completing the Joint Permit Application
(JPA) form which is submitted to the Virginia Marine Resources Agency (VMRC) and DEQ. Upon
receipt the VMRC distributes the JPA to the other resource agencies (USACE, VDEQ, etc.) for review
and comment. Compensatory mitigation for unavoidable impacts to non-tidal Waters and wetlands
will generally be provided at a ratio of 2:1 for forested wetlands, 1.5:1 for scrub/shrub wetlands, 1:1
for emergent wetlands,and a site-specific ratio based on the Unified Stream Methodology assessment
for streams. Mitigation can include: the purchase or use of mitigation bank credits; wetland
preservation; preservation of upland buffers; and in-lieu-fee contribution to the Virginia Aquatic
Resources Trust Fund.
PROCEEDINGS
With your authorization,we will contact the USACE to schedule a field meeting to conduct a wetlands
and Waters boundary confirmation and jurisdictional determination. This process takes an average
of three to four weeks depending on the availability of USACE personnel. After the boundaries of the
wetlands and Waters have been confirmed by the USACE,we suggest that the areas be surveyed for
future planning purposes and be submitted to the USACE as a final record. Once we have determined
potential impacts we can assist you with permitting options and support to complete the process. In
the interim, we recommend further review of state and federal agency records pertaining to Section
7 (Federal Endangered Species Act) and Section 106 (National Historic Preservation Act). These
reviews will generally be required to verify compliance for either the Nationwide Permit (NWP) or
General Permit conditions.
TNT would like to thank you for the opportunity to provide you with this wetland delineation. We
look forward to assisting you further with this project and other environmental concerns you may
have. If you have any questions, please feel free to contact us at any time at(703)466-5123.
Sincerely,
