Project Setting and Background Summary
The Cat Creek stream and wetland restoration site in Macon County, North Carolina was identified by the North Carolina Department of Transportation (NCDOT)
as a potential stream, riparian buffer, and wetland restoration site. The site consists of reaches on four separate tracts of land referred to as: Swartwout, Waldroop,
Parker, and Preserve. The Swartwout, Parker, and Preserve tracts were purchased by the NCDOT, while the Waldroop tract is in private ownership. Following
initial studies of the site by NCDOT beginning in 2002, the site was turned over to the Ecosystem Enhancement Program (now Division of Mitigation Services) in
2005 for final design, construction, and monitoring. A permanent Conservation Easement was obtained for the Waldroop tract. The Waldroop Conservation
Easement was recorded in 2008.
The restoration area entails 7,105 linear feet of Cat Creek, and 948 linear feet of four small tributaries in a rural area of Macon County. Cat Creek and the
tributaries have been impacted by past land use including use as pastureland and a golf course. Both stream restoration and enhancement was proposed for the
various reaches of Cat Creek dependent upon the existing stream conditions and other constraints. The type of restoration by tract is presented in table 1 below.
Wetland restoration and enhancement also occurred on the Swartwout, Parker, and Preserve tracts. Restoration activities were performed to restore pre-disturbance
hydrology to the site by removing fill and drain tiles. Following fill removal these areas were planted with native hardwoods. Areas proposed for enhancement are
areas that still retained hydrology to qualify as jurisdictional wetlands. These areas, at a minimum, were planted with hardwoods. In some of the enhancement
areas, hydrologic enhancement also occurred with the removal of drain tiles. Livestock were removed from the Swartwout Tract.
In December 2013 (Monitoring Year 4), wetland boundary delineations were performed to confirm the boundary of wetland features on the project site. A Level-II
Routine Determination method, as outlined in the USACE Wetlands Delineation Manual (1987), was used to identify wetland boundaries. A total of 8.97acres of
wetlands were delineated within the project site, including 7.55 acres of restoration and 1.42 acres of enhancement. The MY4 wetland boundary delineation
indicates a 1 acre expansion in total wetland area compared to the original baseline delineation of 7.97 acres. The shift in acreage is a result of a 0.13 acre and 0.02
acre loss on the Swartwout and Cat Creek Preserve tracts, respectively, and a 1.15 acre expansion on the Parker tract. The 0.13 acre loss on the Swartwout tract
failed to meet the hydric soil field indicator. The 0.02 acre loss on the Cat Creek Preserve tract failed to meet hydrology success criteria 3 of the 4 monitoring
years. Most of the expansion on the Parker tract was along the right and left descending banks on the upstream end of the tract, as well as several areas along the
periphery of previously delineated areas. Assets in the maps depicted as “not meeting” have been removed from the mitigation assets.
In general, the easement is well vegetated with both herbaceous and woody stems well established throughout the project. The stream components have exhibited
stability since MY1 after an initial settling, post-construction. Minor areas of deposition and scour were noted throughout all reaches, but did not exceed a level
expected in natural stream systems. Remediation activities associated with the project were related to beaver activity on the lower end of the Parker and Preserve
Tracts and invasive plant control throughout the project (Figure 4). Beaver dams were promptly removed with only temporary impacts to the channel bed and
bank documented. Likewise, herbaceous vegetation was temporarily impacted within impounded areas, however has since re-established. A total of four invasive
plant control treatments were applied, with one additional treatment planned for 2015.

Goals and Objectives
As stated in the March 2011 Cat Creek Mitigation Report, the specific objectives and goals of the project are as follows:
Project Goals:
Provide a stable stream channel for the main channel and the unnamed tributaries to Cat Creek that neither aggrades nor degrades while
maintaining their dimension, pattern, and profile with the capacity to transport their watershed’s water and sediment load.
Improve water quality to the receiving watershed through stream bank stabilization measures, the installation of a riparian buffer, and the
exclusion of livestock.
Improve aquatic habitat of the main channel and tributaries with the use of natural material stabilization structures such as root wads, rock
vanes, woody debris, and a riparian buffer.
Provide aesthetic value, wildlife habitat, and bank stability through the creation or enhancement of a riparian zone.
Create contiguous wildlife corridor and provide diverse amphibian habitat with added topographic and wetland features.
Provide shading and biomass input to the stream and mast for wildlife when vegetation is mature.
Enhance wetland biochemical and geo-chemical processes over an extended area.
Project Objectives:
Restore or enhance over 8,881 feet of Cat Creek and its tributaries.
Restore a natural riparian buffer .Plant native trees and shrubs throughout site.
Restore or enhance 7.97 acres of swamp forest bog complex wetlands.

Success Criteria:
Success Criteria Measured Parameter Criteria Met
Stream Dimension, Pattern, and Profile- Minor changes
such as settling of the channel and banks, increase in
vegetative density, decrease in width/depth ratio, and
decrease in cross sectional area may occur and can be
interpreted as a shift towards stability. Longitudinal profiles
should show that bedform remains stable. Short term
aggradation and degredation may occur depending on peak
annual discharge. Planform geometry should not change
over the monitoring period.
13 cross-sections (7 riffle and 6 pools); 2,885
feet of longitudinal profile.
Yes- Dimension, pattern, and profile
have remained stable throughout the
monitoring period. Cross-section data
shows relatively little change between
years. Longitudinal profiles indicate that
bedform has remained stable with some
short-term scour and deposition.
Bed Material- D50 and D84 should increase (become
coarser) in riffles and decrease (become finer) in pools. 13 pebble counts at permanent cross-sections
Yes- Substrate is coarser in riffles and
finer in pools. D50 has remained
relatively stable at each cross-section
over the monitoring period.
Stream Hydrology- Two bankfull events occurring in
separate years
Two crest gauges; one on lower Swartwout and
one on lower parker
Yes- A total of five bankfull events were
documented over the monitoring period,
with three occurring in separate years. A
variety of flows were documented in the
watershed.
Wetland Hydrology- 8% success criteria for all wetland
assets 18 groundwater monitoring wells
Yes- With the exception of CC-7 and
CC-18 all wells met hydrology a
majority of the monitoring period.
Assets were adjusted accordingly based
on data from failing wells.
Vegetation- Minimum of 260 stems per acre after year five. 12 permanent vegetation plots
Yes- With the exception of plot 2, 7, and
10, all plots are meeting the vegetation
criterion. When natural stems are
included, all plots exceed the vegetation
criterion.

Property Issues:
A permanent Conservation Easement
was obtained for the Waldroop tract.
The Conservation Easement was
recorded in 2008. Prior to the 2008
cattle and horses had access to the
streams on the property. The
Waldroop tract was included in the
project to connect the existing NCDOT
tracts which are owned fee simple by
NCDOT.
Due to the existing agricultural land
use, the property owners were
unwilling to place a full 30 foot stream
buffer on their section of the project
site. DMS obtained the maximum
amount of conservation easement that
the landowners would approve in 2008.
In addition, DMS acquired an
additional 20 feet from the restricted
conservation easement.
The additional conservation easement
area stipulates that agricultural
practices are currently allowed in this
additional 20 foot buffer area;
however, if the parent tract is ever
taken out of agricultural use, all
conservation easement restrictions will
apply to the full easement area in perpetuity. In December 2013, the landowners placed the entire parent tract in a farm conservation easement. Based on this
unique easement and the additional buffer on the three tracts owned fee simple by NCDOT, DMS is requesting that the Enhancement I and II project credits on the
Waldroop tract not be reduced.

“Easement Area B - All reserved uses and restricted activities for Easement Area A set forth above apply to Easement Area B with the exception of E (Agricultural
Use). No waste lagoons or permanent structures may be placed in Easement Area B at any time, however, cropland and pastureland uses are allowed in
accordance with agricultural best management practices. Such practices are allowed in Easement Area B, as long as the parent tract is being used by the Grantor
as cropland, pasture land, or other agricultural uses, as defined by the North Carolina General Statute Related to Present Use Values: G.S. 105-277.2, and in
accordance with water quality protection goals. If the parent tract is ever taken out of such agricultural uses, Grantor shall notify Grantee of this change, and
then all restrictions above that are specified for Easement Area A will then apply to Easement Area B, including restrictions specified in II. E.”

An approximately 400 foot section of fencing was identified inside of the easement during closeout preparation. The
landowners will move this fence to the conservation easement line in July 2015.

A dilapidated NCDOT cross pipe and stormwater runoff adjacent to DOT bridge # 198 have caused scour on the corner of Cat Creek
Road and Jack Cabe Road (downstream end of the Swartwout tract). NCDOT will be repairing the cross pipe and the area adjacent
to bridge # 198 in August 2015.

EEP Recommendation and Conclusion
Overall the project has met its goals of providing a stable stream channel, improving water
quality, aquatic habitat, and providing improved wildlife habitat and connectivity in the stream
and riparian corridors.
Both herbaceous and woody vegetation has become well established throughout the project
easement. The annual mean stem density in Year 5 was 384 stems per acre, well above the
success criterion of 260 stems per acre for Year 5 (Table 7). Plots 2, 7, and 10 failed to meet the
planted stem density criterion, however, when natural recruits are included all plots are well
above the criterion. Herbaceous vegetation is well established throughout the easement,
particularly in wetland restoration areas where a dense, diverse herb layer has developed.
Stream restoration and enhancement areas show stable dimension, pattern, and profile (Figures
6-7 and Table 4) according to both morphological survey data as well as visual assessment of the
site. Cross-section and longitudinal profile data demonstrate stable channels throughout the
project.
A total of five bankfull events have been documented at the project site with three occurring in
separate years (Table 5). More events likely occurred during the monitoring period. The USGS
Cartoogechaye Creek gauging near Franklin, NC—located in a neighboring watershed—
indicates that the area and Little Tennessee watershed have experienced a variety of flows during
the monitoring period (Figure 7).
Groundwater monitoring results indicate that with the exception of CC-18, all wells are meeting
the 8% hydrology criteria (Table 6). Assets in the vicinity of the failing well was adjusted
accordingly during an MY4 wetland delineation (Figure 1).
In summary, the Cat Creek Restoration Site is meeting success criteria for channel stability,
wetland hydrology, and vegetative survival as outlined in the original restoration plan. NCDMS
recommends submitting the project for regulatory closure and requests a total of 6,429 SMUs
and 8.13 WMUs.

71 - Cat Creek
Watershed Characteristics Overview
The Cat Creek project is located in eastern Macon County, approximately 3 miles east of the
Town of Franklin in the Little Tennessee River Basin (CU 06010202). It is located within HUC
06010202040010 (Watauga-Rabbit-Cat Creeks), which is listed as a Targeted Local Watershed
(TLW) in the 2008 Little Tennessee River Basin Restoration Priorities (RBRP) plan and is
located within the Franklin to Fontana Local Watershed Plan (LWP) area. The TLW is 25
square miles in area, comprising a predominantly rural landscape of private forest lands, rural
homes and cattle farms, except for the Lake Emory subwatershed, which drains urban/suburban
portions of Franklin. Based on information in the 2010 Franklin to Fontana Watershed
Assessment Report, the 3.7-square mile Cat Creek subwatershed (within the TLW) is
characterized by 21% agriculture, 67% forest cover, and 12% developed area. The Cat Creek
subwatershed includes 34% degraded (non-woody) riparian buffers (as a percentage of total
stream channel length) and significant pasture areas (321 acres) where livestock have direct
access to stream channels. Also, a total of 22 miles of unpaved roads exist within the Cat Creek
subwatersheds. The Cat and Rabbit Creek drainages within the TLW are identified as two of the
most highly impacted subwatersheds within the Franklin to Fontana LWP area and are priority
subwatersheds for stream and wetland restoration.
