Phase IV Watershed Assessment South Hominy Creek Watershed March 2007
Introduction The North Carolina Ecosystem Enhancement Program (NCEEP) contracted with Buck Engineering to develop a local watershed plan for the South Hominy Creek Watershed in the French Broad River Basin. The objective of this plan was to develop a set of management strategies to restore and protect the functional integrity of the watershed. The present document is a result of Phase IV of the planning process, and it identifies and prioritizes stream and wetland project opportunities to address functional deficits. This work is being completed as part of the Local Watershed Planning (LWP) initiative that is administered by the North Carolina Ecosystem Enhancement Program (EEP). This fourth phase of the assessment presents a Stream Mitigation Opportunity Atlas with a prioritized list of potential stream mitigation project sites based on work completed summarized in four project memos and recent efforts. The HU of interest is the South Hominy Creek Watershed, (HU 06010105060020) which is located in the southwest portion of Buncombe County and has an area of 38.4 square miles. This watershed includes the communities of Beaverdam, South Hominy, Stony Fork, Glady, Dunsmore, and portions of Candler. Pisgah National Forest spans the southern and southwestern periphery of the watershed and composes approximately 22.3% of the total watershed area. There are four major tributaries in the watershed: Beaverdam Creek, Stony Fork, Glady Fork, and Warren Creek. In Phase IV, specific project sites were identified and prioritized based on a number of factors including the potential for functional improvement, site constraints, potential stream mitigation units (SMUs), location within the watershed, and the number of landowners per site. An initial list of potential project sites was created based on stream length and the number of landowners per project using GIS. These sites were then visited to determine constraints, restoration approaches, and the potential for improvement. All potential sites were then prioritized based on observations and collected data and undesirable sites were culled. This report presents a GIS based atlas of the prioritized sites along with photos and a site assessment.
Methods Base mapping of the South Hominy Watershed was complied in GIS using aerial photography flown in 2002 and Buncombe County parcel data from 2006. GIS was used to make an initial list of potential stream mitigation sites. These sites were identified based on stream length and the number of landowners per site. The stream length cutoff for a project was 2,000 feet. This cutoff is due to the economies of scale when considering design and construction costs. Projects with numerous landowners were eliminated to save time and effort with landowner negotiations. For a site to be considered it had to have no more than 4 landowners per 2,000 linear feet of stream.

The number of parcels and landowners per project site was determined using GIS parcel and stream data. However, these determinations were often difficult to make because of the limited detail represented in the GIS parcel layers. For example, it is often unclear whether a property boundary is defined by the location of a stream channel or nearby road. In the atlas, project parcels are outlined in blue and non-project parcels are outlined in gray. Appendix 1 gives parcel numbers, landowner names, and contact addresses for all of the project parcels and relates them to a prioritized project site. An effort was also made to demonstrate circumstances where one landowner owns several properties on one project site as this would lessen the number of necessary landowner negotiations. In the atlas, parcels are shaded to represent instances when one person owns more than one parcel on a single restoration site. This information is subject to interpretation based on variations in spousal and corporate ownership as well as inconsistencies with spelling and abbreviations in the parcel geodatabase. For example, an individual may own two properties; one that is listed in his name in the parcel database, and another that is listed in the name of his company. In instances such as this, the properties are represented in the atlas as owned by two individuals. Site visits were conducted in December 2006 and January 2007 to quickly assess the sites, identify constraints, and determine appropriate restoration strategies. Generally, landowner permission was not obtained for these site visits. Sites were inspected from roads and other areas with public access. Site Assessment Forms were filled out during these visits. Observations and recommendations made during the site visits should be viewed within this context and the potential SMUs listed for each site are rough estimates. Sites that were determined to be particularly promising were revisited to collect cross-section data, with landowner permission. These data are displayed in the atlas along with the site assessments. Wetlands that were identified in Technical Memo 3 and during the most recent site assessments are also included in the atlas. The identification of wetlands was conducted using a combination of GPS points, field data, and remote sensing data (as noted in section 2.3.5 of Technical Memo 3). The only site that has any of the identified wetlands located on project parcels is Glady Fork #2. This site has an estimated 1.1 acres of potential wetland restoration. Potential agricultural and stormwater best management practices (BMPs) are also identified. BMP strategies include fencing livestock out of streams, controlling sediment from gravel roads, and constructing stormwater detention wetlands. These BMPs are included in the descriptive assessment of the site. Restoration approaches are suggested for each site and the corresponding SMUs are calculated. For the purposes of mitigation credit, the US Army Corps of Engineers defines a stream improvement hierarchy with the associated SMU credit generation (USACE, 2003). For the purposes of this report, conservative estimates of potential SMUs per site were made by using the lowest ratio (stream feet repaired to SMUs earned) provided by the USACE per hierarchical level as follows:

Assumed SMU Ratio* 1:1 1.5:1 2.5:1 5:1
*Stream feet repaired to SMUs earned
Site constraints such as structures, power lines, ponds, and roads located near streams that could limit restoration options were identified at each site. Each site was given a score according to a qualitative assessment of these constraining factors. Sites with many constraining factors were given a score of 1, sites with some constraining factors were given a score of two, and sites with few constraints were given a 3. An example of a site with few constraints is a preservation stream on which there are no structures or roads that would interfere with an easement. An example of a site with many constraints is a reach in need of restoration that parallels a road and has several structures located within 50 feet of the channel. These constraints were helpful in narrowing the list and prioritizing the sites. Constraints at each site are described in the individual assessment forms. The opportunity for improvement at each site was also qualitatively assessed and assigned a numerical value for the purposes of ranking. Preservation sites were given low scores as these sites will be protected but not improved. Severely impaired sites where livestock access the streams were given high scores. The opportunity for improvement was also useful in prioritizing the sites and is described in the individual assessment forms. The location of each site within the watershed was used as a ranking category. This ranking was driven by priorities identified by stakeholders during Phase III of the Local Watershed Planning (LWP) process. Streams located adjacent to forested headwater streams were identified as the highest priorities because of the potential to restore or preserve ecological connectivity. The Beaverdam drainage of South Hominy watershed was identified as a lower priority because stakeholders felt there was less opportunity for restoration and less chance for functional uplift due to impacts in the drainage. The ranking system that was developed for the location of streams within the watershed placed streams not adjacent to forested headwaters in the lowest category, Beaverdam streams adjacent to forested headwaters in the middle category, and South Hominy streams outside of the Beaverdam drainage and adjacent to forested headwaters in the highest category. After the GIS and field assessments were completed, sites were prioritized based on five categories: length of stream per landowner, potential for improvement, on-site

constraints, SMUs, and location within the watershed. A priority matrix was used to rank the sites. Each site was scored according to the following parameters: • • • • •
Opportunity for improvement: low 1, moderate 2, good 3, excellent 4 Site constraints: many 1, some 2, few 3 Site location within the watershed: streams not adjacent to forested headwaters 1, Beaverdam streams adjacent to forested headwaters 2, South Hominy streams outside of the Beaverdam watershed that are adjacent to forested headwaters 3 Feet of stream per project divided by the number of landowners: 504 to 5,290 Estimated SMUs: 771 to 5,535
The numerical values of the scores vary greatly between categories. For example, SMUs generated per site vary from 771 to 5,535, while the opportunity for improvement varies from 1 to 4. To be able to prioritize the sites based on all of the prioritization categories the category scores are normalized. This was done by dividing the true score by the largest possible score per category. To illustrate, a stream with a low opportunity for improvement and a score of 1 is normalized by dividing by 4 (the largest possible value for this field) and thus calculating a prioritized score of 0.25. The result of this strategy is that the score for all normalized priority categories rank between 0 and 1. The five prioritization categories are then summed per site to achieve a final multi-parameter priority ranking (Table 3). Project cost estimates are also provided. These cost estimates include permitting, design, construction, five years of monitoring, and land costs of $10,000/acre. Table 2 shows the costs per linear foot assumptions used to generate these estimates. The ranges that are provided allow for adjustments according to site specific strategies, stream length, and constraints such as excessive earthwork. For example, the cost per linear foot would have been priced on the lower end of the range that is provided in Table 2 for a restoration project on a 4,000 foot stream reach with a small drainage area running through a field with few constraints. Project cost estimates are rough, often based only on aerial photography and roadside visits. Detailed information such as rock requirements and variations in land prices were not considered. These estimates should be considered cautiously. The project costs are displayed in the priority matrix but were not used as a ranking category. Table 2 Cost Assumptions for Project Sites

Results and Conclusions Of the 73.6 miles of mapped streams in the South Hominy watershed, 20 miles or 27 percent were identified as potential project streams. In comparison, of the 4,334 parcels in the same area, only 127 parcels or 0.62 percent were identified as potential project parcels. There are less than 100 landowners who own these 127 parcels. Overall, site lengths range from 1,960 to 9,950 feet and the potential SMUs generated per site range from 771 to 5,535. Twenty-seven sites and 68,944 SMUs were identified through this process. The combination of sites ranked with the highest priorities of 1 through 13 meet the project goal of generating 40,000 SMUs. Figure 1 presents an overview of these sites and their locations. Figure 2 is a representation of the priority matrix used to rank each site; Table 3 provides assessment scores for the sites based on parameters including location, constraints, project length, opportunity for improvement, and potential SMUs.

Figure 2 shows the Stream Restoration Site Prioritization Tool that was developed to aid in decision making when selecting sites for further investigation. This figure gives a graphic representation of each prioritization category at each site along with the forecasted project costs. The bars and right axis show forecasted project costs. The colored areas and the left axis show the priority rankings at each site. Each color represents a category. The total area represents the category rankings summed, so the upper line indicates the final prioritization ranking. Figure 2 Stream Restoration Site Prioritization Tool
This figure is helpful in understanding why the sites are ranked as they are and may be useful in targeting sites based on one of the represented categories. For example, sites ranked between 14 and 21 have a similar overall priority ranking. If the EEP is looking at these eight sites and is trying to maximize SMUs then Site 20 might be chosen. Or if the EEP wants a site in a beneficial location, Site 14 might be chosen.

Another issue that the Stream Restoration Prioritization Tool brings up is the ranking of preservation sites. Preservation sites ranked seven and eight by their nature will be inexpensive, have few constraints, and a high number of feet per landowner. These sites also inherently have a low opportunity for improvement.

This site is located on South Hominy Creek and on two tributaries to South
Hominy Creek by Davis Creek Road and Pisgah View Ranch Road. This is a large project maintained as one site because the streams are contained primarily within the Pisgah View Ranch owed by the Cogburn family (Ranchlands Inc). Streams on this site vary in size (drainage areas from 0.23 to 4.40 sq miles) and condition.
Some sections are fully functional, some sections are straightened and channelized with
minimal riparian buffers, and in some areas damage from hurricanes Ivan and Francis is still visible.
Riparian Vegetation: The upper reaches of Tributaries 1 and 2 (Photo 1) are largely forested (except for 400 feet on the uppermost right side of reach 2). Invasives are growing along Tributary 1. Down from these reaches the riparian buffers vary greatly in width from nonexistent to greater than 100 feet.
Wetlands:
None
Expected Restoration Type and General Approach:
This site has potential for restoration,
enhancement, and preservation. The forested upper reaches on Tributaries 1 and 2 may be suitable for preservation. Downstream from these reaches a mix of restoration and enhancement will be appropriate.
Potential BMP Opportunities:
There are several fields on the property that have streams running
through them. The streams are generally not fenced to prevent livestock access. No horses having direct access to streams were observed. However, if horses are occasionally kept in these fields they should be fenced out of the streams.
11
Constraints (bridges, utilities, structures, natural areas): Overall, there are relatively few constraints in this site as a whole. Several structures are located near the streams and there are several road crossings. There is also a large pond located off of Tributary 2. These constraints should not pose a significant threat to a successful project.
Potential for Improvement (water quality, hydrology, habitat):
All functional aspects of the
streams may be improved by restoring dimension, pattern and profile; allowing the stream greater access to its floodplain; controlling erosion; fencing horses out of the stream, restoring bedform diversity; and enhancing riparian buffers. These streams display varying degrees of need but considering the size of the site, the potential for improvement is good.
Landowner Contact: Buck personnel spoke with Mrs. Cogburn while doing the site assessment. She is aware of this program and may be open to a restoration project on her property.

Existing Conditions:
This site is located on Sam’s Branch near Sam’s Branch Road and includes
several tributaries to Sam’s Branch. Many of the streams on this site have been straightened and are incised. Sam’s Branch closely parallels Sam’s Branch Road and functions as a ditch (Photos 4 and 5). Upstream portions of the project are forested (Photos 1 and 2). Though much of the landuse surrounding these streams is pasture, no livestock were noted as having access to the creek at the time of inspection. According to the parcel data, Ellen and Johnnie Davis own approximately 3000 feet of this project reach. Their land alone could support a project.
Riparian Vegetation:
The riparian buffer in this reach varies from nonexistent to over 100 feet wide.
Invasive plant species are present throughout the project reaches.
Wetlands:
None
Expected Restoration Type and General Approach: Stream improvements at this site may include a combination of restoration and enhancement level II. Conditions vary from lightly impacted to extremely degraded. Generally, the forested areas may be improved through enhancement level II techniques such as the removal of invasive species and the areas without riparian buffers may be improved through full restoration practices. Wherever possible, the stream should be moved away from the road.
Potential BMP Opportunities:

Constraints (bridges, utilities, structures, natural areas): Several constraints exist on this project site. Sam’s Branch Road parallels the stream, coming within 20 feet of the channel. However, in this case because of the flat topography the stream may be moved away from the road. This alignment may be considered an opportunity for improvement rather than a constraint. Other constraints include a pond adjacent to the stream, driveway crossings, and power lines. On the Davis property none of these constraints are significant factors. Considering the size of this project, constraints present a minimal threat to a successful project.
Potential for Improvement (water quality, hydrology, habitat):
Restoration at this site has the
potential to improve all functional aspects of the stream. However, the channel is not incised or unstable throughout the entire project site and it appears that livestock do not have access to the stream. Therefore, the potential for improvement here is good but not great.

Preservation (ft):
This site is located on Glady Fork and includes 3 tributaries to Glady Fork along
Upper Glady Fork Road. The site is contiguous with Glady Fork #1. Streams on this site generally run through pasture and mowed fields. These streams are incised and have minimal riparian buffers. On Tributaries 1 and 2 livestock have access to the stream channels which are trampled and lack bedform diversity. The headwater of Tributary 2 is located within the project parcel boundaries. The upper portion of Tributary 1 may be intermittent. Several potential wetlands that were identified in this and previous surveys are located on this site. Tributary 3 was flowing during the site visit but may be intermittent.
Riparian Vegetation:
Riparian buffers throughout this project reach vary in width between nonexistent
and one tree wide.
Wetlands:
Four potential wetland restoration locations were identified on this site. These are areas
in mowed fields and pastures where livestock access the wetlands.
In total, the estimated wetland
restoration area is 1.1 acres.
Expected Restoration Type and General Approach: Stream improvements at this site should involve restoration throughout. This is a classic restoration site running through pasture and fields with a minimal riparian buffer and few constraints. The mainstem has a rather large drainage area but the smaller tributaries originate within or near the property boundaries. This large site has over 5,000 possible feet of restoration. Within this site, 2,500 feet of stream are owned between just two landowners. This portion alone would be a suitable restoration project.
26
Potential BMP Opportunities:
Fence livestock out of streams and wetlands.
Constraints (bridges, utilities, structures, natural areas): Constraints near this site include road crossings and a few structures.
Overall, these constraints are minor and pose little threat to the
implementation of a successful project.
Potential for Improvement (water quality, hydrology, habitat):
Restoration here would greatly
improve all functional aspects of the stream by restoring pattern, profile, and dimension; stabilizing the banks; fencing out cattle; allowing the stream access to its floodplain; and enhancing the riparian buffer. Work done at this site would greatly improve the functionality of this stream.
Landowner Contacts:
Mr. Ray Pressley (101) the largest landowner at this site was contacted and is
currently not interested in the program. Kristen Hillegas and Mary Lyn Roman (108) were also contacted and they signed a site proposal form. Evangeline Wheeler and her daughter Kathy Edwards (104) are interested in the project and also signed a site proposal form. Dale Edmunds (107) has been contacted by Land Quality about grading and erosion problems on his property and may be opposed to a state project. P. J. Duck (103) is not interested in the program. Kathryn Wagner (Moody) (99) and husband Thomas Wagner have an interest in the program but did not sign a site proposal form.

Preservation (ft):
Existing Conditions:
This site is located on an unnamed tributary to Beaverdam Creek along Smith
Cove Road and a short section on Beaverdam Creek. These streams have been straightened and the majority of this site has no riparian buffer. Cows have direct access to much of the downstream portion of the site. The middle portion the unnamed tributary to Beaverdam Creek flows through a community park. Upstream from the park is first a mowed field, then a residential area with several nearby ponds, and finally an area where more cows have access to the stream. Part of this upstream section has been channelized and the banks reinforced with brick walls (Photo 1). Downstream from the community park land use is pasture and cows have access to the streams.
Riparian Vegetation:
Generally, the riparian buffers on this project reach vary in width between
nonexistent and one tree wide. There are short isolated areas with wider buffers.
Wetlands:
None
Expected Restoration Type and General Approach: Stream improvements at this site should involve enhancement I on the upper half and restoration on the lower half. In the upper half of the site adjusting dimension and enhancing the riparian buffer is appropriate. In the downstream half, sinuosity should be increased and the brick walls that are reinforcing the banks should be removed. A functional pattern, profile, dimension, and riparian buffer should be returned to the stream.
Potential BMP Opportunities: Livestock should be fenced out of the stream. Erosion control devices should also be placed by the borrow pit (Photo 3) to prevent sediment from entering the stream.
34
Constraints (bridges, utilities, structures, natural areas): Constraints near this site include roads, road crossings, power lines, ponds, and structures. It may be difficult to get landowner approval for removing the brick walls that line the channel. This project reach is so long that even if the upstream landowners do not grant an easement the downstream portion could still present a viable project. Constraints on this reach pose a slight threat to a successful project.
Potential for Improvement (water quality, hydrology, habitat):
Restoration here would improve all
functional aspects of the stream by restoring pattern, profile, and dimension; fencing livestock out of the channel; reducing erosion; and enhancing the riparian buffer. The reaches where livestock access the stream are severely degraded and have a particularly high potential for improvement (Photos 4 and 6). Restoration at this site would greatly improve the functionality of this stream.
Landowner Contacts:
Robert and Vicki Warren own five parcels along this site (46, 48, 97, 100, 106).
We attempted to contact these landowners to determine if they would be interested in a project. We were referred to their attorney, Ms. Cathleen Fish (667-0875). Apparently their property has been seized by the federal government over tax issues and there isn’t a timetable for resolving the case. No other landowners at this site have been contacted.

Preservation (ft):
Existing Conditions: This site is located on Curtis Creek along Curtis Creek Road and Ladybird Lane. This site is composed of a 660 foot reach on Curtis Creek and a 3,040 feet on two unnamed tributaries to Curtis Creek. The Curtis Creek reach has been straightened and is very incised. The unnamed tributaries to Curtis Creek are also generally very incised (except in the uppermost sections). These streams appear to be perennial near their confluence and the headwaters likely occur within the project parcel. The tributaries run through pasture where, in sections, cattle are not fenced out. They are trampled and lack bedform diversity as a result.
Riparian Vegetation: The riparian buffer on Curtis Creek is less than 20 feet wide on both sides with few trees and many invasives. The right bank is bordered by pasture and the left bank is next to a equipment storage site. The tributaries have virtually no riparian buffer and flow through pastureland.
Wetlands:
None
Expected Restoration Type and General Approach: On the Curtis Creek reach, stream improvements should involve enhancement level I in the form of restoring pattern, dimension, and a riparian buffer. On the unnamed tributaries to Curtis Creek full restoration would be appropriate including restoring pattern, profile, and dimension as well as planting a riparian buffer and fencing out the cattle.
Potential BMP Opportunities:
Fencing out cattle from the unnamed tributaries will improve water
quality.
41
Constraints (bridges, utilities, structures, natural areas): Constraints at this site include several driveways, road crossings and structures near the tributaries as well as an equipment storage area adjacent to Curtis Creek. Though there are several constraints at this site, there are few constraints in the upper reaches of the tributaries which contain a good deal of stream length.
Potential for Improvement (water quality, hydrology, habitat): Enhancement and restoration here would improve all functional aspects of the stream by reducing erosion, allowing storm flows to access a floodplain, increasing bedform diversity, keeping cattle out of the stream, and restoring a functional riparian buffer. This site has a great potential from improvements.
Landowner Contact:
Marie Elliot, the primary landowner at this site, was contacted and is not
interested in the program at this time.

Existing Conditions: This site is located on South Hominy Creek by South Brooks Cove Road and an unnamed tributary to South Hominy Creek. A mowed field boarders the stream on the left with a riparian buffer separating the stream from the field by at least 40 feet. The field does not appear to be used for agricultural purposes. The upstream section is not incised and has a relatively fully functioning riparian buffer. The downstream section of this stream is incised and the riparian buffer is impaired. This site is contiguous with South Hominy Creek #4.
Riparian Vegetation: On South Hominy Creek the left bank has a functioning (upstream) to impaired (downstream) riparian buffer. This buffer width varies from 40 to 150 feet. On the right bank the riparian buffer is generally fully functioning (except at the uppermost section of the reach) with a width of greater than 100 feet. On the left bank the buffer is mostly intact in the upstream section but generally gets narrower in the downstream direction. There are invasives growing in the downstream portion of the site. The unnamed tributary to South Hominy Creek has no riparian buffer and invasives growing throughout.
Wetlands:
None
Expected Restoration Type and General Approach: The downstream section of South Hominy Creek would benefit from level II enhancement.
The banks should be stabilized and riparian vegetation
enhanced. The uppermost section would likely be preservation. The unnamed tributary to South Hominy Creek has been channelized and would benefit from full restoration.
50
Potential BMP Opportunities:
Erosion control along dirt roads would lessen the supply of fine
sediments to downstream reaches.
Constraints (bridges, utilities, structures, natural areas): Constraints include the road crossings at South Brooks Cove and Smathers Roads and a barn on the downstream end located within 35 feet of South Hominy Creek. These constraints should not pose a significant threat to a successful project.
Potential for Improvement (water quality, hydrology, habitat):
Water quality, hydrology, and
habitat may all be improved by allowing the stream greater access to its floodplain, controlling erosion, and enhancing riparian buffers. This stream is not severely impaired. So, the potential for improvement is less than what might be realized in a more damaged stream.
Landowner Contact: The entire site is owned by the Cogburn family, the same family who also own the majority of South Hominy #2 and South Hominy #4. South Hominy #2 is listed as having the highest priority in this atlas.

This site is located on several unnamed tributaries to South Hominy Creek along
McFee Road. Landuse in the area is varied. Livestock have access to the streams which are in pasture (Photos 3 and 4). There are little to no riparian buffers in the pasture and agricultural areas. The stream is straightened, trampled, and lacks bedform diversity. The short tributary in the downstream portion of the project reach has recently been channelized and straightened (Photo 2). At the time of the original investigation these banks were raw earth, but have since been reseeded.
Riparian Vegetation:
The riparian buffers on this project vary in width between nonexistent and
greater than 100 feet. Agricultural landuse in the area is intense, with stream bank conditions that approach those seen in Photo 2.
Wetlands:
None
Expected Restoration Type and General Approach: Work done at this site should involve a mix of enhancement level II and restoration. In the downstream portions of the project, where there is no riparian buffer, land use is agricultural and pasture. Stream improvements should involve restoration. In the upper reaches, where the stream is less impacted, improvements should involve enhancement level II practices such as enhancing the riparian buffer and isolated areas of bank stabilization.
Potential BMP Opportunities:
Livestock should be fenced out of the stream.
59
Constraints (bridges, utilities, structures, natural areas): Constraints near this site include road crossings, utility lines, agricultural fields, and structures. These constraints should not pose a significant threat to a successful project.

In the upstream portion of this project reach the stream has been
straightened and flows through a mowed field (Photo 1, 2, and 3). In the middle portion cattle have access to the stream and the channel is trampled, over-wide, and lacks bedform diversity (Photos 4 and 5). The downstream portion the stream is forested and in good condition.
Riparian Vegetation: The riparian buffer widths on this project reach vary between 0 and over 100 feet. There are invasives growing in the existing upstream buffers.
Wetlands:
None
Expected Restoration Type and General Approach: Stream improvements at this site should include full restoration throughout the upper 3,865 feet. A functional pattern, profile, dimension, and riparian buffer should be returned and livestock fenced out of the stream. In the downstream section preservation will be appropriate. Aside from this creek having a rather large drainage area, this should be a typical restoration site.
Potential BMP Opportunities:
Fence out livestock.
Constraints (bridges, utilities, structures, natural areas): Constraints located near this site include roads, road crossings, power lines, and structures. These constraints should not pose a significant threat to a successful project.
65
Potential for Improvement (water quality, hydrology, habitat):
Restoration here would improve all
functional aspects of the stream by restoring pattern profile, and dimension; fencing livestock out of the channel; reducing erosion; and enhancing the riparian buffer. This site is in great need of restoration.
Landowner Contacts: The inspector spoke with Mr. Clark’s son who reported that Mr. Clark, the upstream landowner, had already been contacted and is unlikely to be interested in a stream restoration project on his property. This project reach would still be approximately 3,700 feet long without Mr. Clark’s segment.

This site is located on an unnamed tributary to South Hominy Creek along Upper
Glady Fork Road. Short sections of other streams are also included on these parcels and should be included in this site. The majority of this site flows through pastureland and livestock have access to these reaches. There is little to no riparian buffer. The stream is trampled and lacks bedform diversity. 1,700 feet of this project stream is located on one parcel owned by Paul and Martha Moses. This section is in the greatest need of improvements and may be long enough to serve as its own project.
Riparian Vegetation:
Riparian buffers on this project vary in width between nonexistent and one tree
wide. There are short areas with wider buffers.
Wetlands:
None
Expected Restoration Type and General Approach: Stream improvements at this site should involve restoration throughout the length of the streams. Functional pattern, profile, dimension, and riparian buffers should be returned to the stream. The stream runs through a field so design and construction should be relatively straight forward. The stream is not severely incised so earthwork will not be a major concern.
Potential BMP Opportunities:
Livestock should be fenced out of the stream.
Constraints (bridges, utilities, structures, natural areas): Constraints near this site include road crossings, power lines, and structures.
These constraints should not pose a significant threat to a
successful project.
72
Potential for Improvement (water quality, hydrology, habitat):
Restoration here would improve all
functional aspects of the stream by restoring pattern, profile, and dimension; fencing livestock out of the channel; reducing erosion; and enhancing the riparian buffer. Restoration at this site would greatly improve the functionality of this stream.
Landowner Contact: Mr. Moses has been contacted regarding this program. It was not clear if Mr. Moses would be interested in participating in a project.

This site is located past the end of Sam’s Branch Road. The reach is the
headwater of Sam’s Branch. “Posted, No Trespassing” signs prevented any inspection or photography of the site. According to aerial photography, this is a steep mountain stream that is surrounded by forest.
Riparian Vegetation:
Because of its remote location, it is assumed that the vegetation surrounding this
site is primarily composed of native species.
Wetlands:
None/Unknown
Expected Restoration Type and General Approach:
It is assumed that this site is in a relatively
pristine condition and would be a candidate for preservation only.
Potential BMP Opportunities:
Constraints (bridges, utilities, structures, natural areas): Because of its forested nature, it is unlikely that any constraints on this site would pose a significant threat to a successful project.
Potential for Improvement (water quality, hydrology, habitat):
It is likely that this reach is fully
functional. Preservation here would prevent future degradation to this stream.

This site is located on Curtis Creek along Curtis Creek Road and on two
tributaries to Curtis Creek. The Curtis Creek reach runs through residential and agricultural areas and has virtually no riparian vegitation.
This reach is incised and over-wide.
Tributary 1 flows through
residential, agricultural, and some forested areas (Photos 3 and 4). This channel is very straight and currently functions as little more than a ditch. Tributary 2 is bordered by a field on the right bank and forest on the left bank. This stream is extremely incised, but has created bankfull benches in places.
Riparian Vegetation: The riparian buffers on these reaches generally vary between 0 and 25 feet wide. The exception to this is left bank of Tributary 2 where the riparian buffer is greater than 100 feet wide.
Wetlands:
None
Expected Restoration Type and General Approach: All three of these reaches are candidates for full restoration. Furthermore, restoration of these tributaries is greatly needed. The pattern, profile, and dimension should be returned to a functional condition and riparian areas should be either established or enhanced.
Potential BMP Opportunities:
Fence out livestock.
Constraints (bridges, utilities, structures, natural areas): Constraints in this project reach include roads and homes. Two driveways and three homes are located within approximately 50 ft of Curtis Creek and Tributary 1. The agricultural land is also intensely utilized in this area. These constraints may limit restoration options at this site, especially in the downstream areas.
81
Potential for Improvement (water quality, hydrology, habitat): Restoration here would improve all functional aspects of the stream by reducing erosion, allowing storm flows to access a floodplain, increasing bedform diversity, fencing out livestock, and enhancing the riparian buffer. This site has a very good potential for improvement.

This site is located at the end of state maintained Warren Creek Road. This
reach is the headwater to Warren Creek. “Posted, No Trespassing” signs prevented a thorough inspection of the site. The only portion on the stream that was accessible to the public was the downstream portion, which crosses under Warren Creek Road (Photo 1). This is a steep mountain stream that is primarily surrounded by forest.
Riparian Vegetation:
Invasive plants were noted in the downstream portion of the reach during the
site visit. Though the upstream portion was not investigated, it is assumed to be in a more natural state.
Wetlands:
None/Unknown
Expected Restoration Type and General Approach: From aerial photography, the downstream half of this reach appears to parallel a private driveway. Though the entire reach was not inspected, invasives were seen at the very downstream end and it is assumed that site disturbance along the driveway has introduced invasive plants. Stream improvements on this downstream portion would likely involve enhancement level II techniques through the removal of invasive plants. It is assumed that this will be a candidate for preservation because of its remote location.
Potential BMP Opportunities:
Constraints (bridges, utilities, structures, natural areas): No significant constraints were noted during the site visit. It is unlikely that there are any constraints on this site which would pose a significant threat to a successful project.
88
Potential for Improvement (water quality, hydrology, habitat):
Enhancement II and preservation
here would improve habitat by enhancing the riparian buffer and preserving the stream from future degradation.

This site is located on an unnamed tributary to South Hominy Creek along Kile
Road off of Carolina Mountain Drive. The stream has been straightened, is very incised, and flows primarily through fields. The upstream 350 feet of this reach is adjacent to Pisgah Hwy and has recently been disturbed by major road construction (Photos 1 and 2). This short section is extremely incised. The downstream sections of this stream were not accessible without violating “No Trespassing” signs. However, from a distance this section appears to be incised and straightened. It runs through a field and has a limited riparian buffer (Photos 3 and 4).
Riparian Vegetation: The riparian buffer on this project reach generally varies between 10 and 30 feet wide. The exception to this is the right bank on the downstream section where the riparian buffer is greater than 100 feet wide for approximately 650 stream feet. Invasives are growing in the riparian buffers throughout the project reach.
Wetlands:
None
Expected Restoration Type and General Approach:
This stream is a candidate for full restoration
throughout its length. Furthermore, restoration of this stream is greatly needed. Restoration options on the upstream 350 feet are limited because of the number of constraints. The downstream section would be a more traditional restoration project. Earthwork should be a consideration at this site due to constraints
Potential BMP Opportunities: None
93
Constraints (bridges, utilities, structures, natural areas): The main constraints on this project reach are located on the upstream section near the Pisgah Hwy crossing. Constraints in this area include homes, roads, and earthwork.
These constraints make restoration unlikely on this short section.
Fewer
constraints are located in the lower sections of the project. If constraints in the upstream 350 feet prove to be prohibitive, this may still be a viable site with 1870 stream feet left in the downstream reach.
Potential for Improvement (water quality, hydrology, habitat): Restoration here would improve water quality, hydrology and habitat by reducing erosion, allowing storm flows to access a floodplain, increasing bedform diversity, enhancing the riparian buffer, and possibly fencing livestock out of the stream.

This site is located on Curtis Creek along Curtis Creek Road. Generally, the
project reaches have been straightened, run through mowed fields, and have no riparian buffers (Photos 3 and 4). A short tributary is included in this site. The area around this tributary is currently under development and has recently been channelized. Currently, the stream banks along this tributary have no vegetation (Photo 1). Because of public access restraints, the upstream section was not investigated but from aerial photography this section appears to be in a similar condition as the rest. Access to the downstream portion of this project site was also limited but observations made from the road and through aerial photography indicate that this reach is in a somewhat more stable condition (Photo 2). Riparian enhancement and isolated stream bank stabilization may be appropriate for this section.
Riparian Vegetation:
As is obvious through the aerial photography, there is no riparian buffer along
most of this reach. The downstream section does have a buffer that varies between 0 and 60 feet wide. Invasives are common in this downstream section.
Wetlands:
None
Expected Restoration Type and General Approach:
This is a classic restoration project on a
straightened and incised channel that runs through fields with little or no riparian buffer. Restoration in the form of re-establishing functional pattern, profile, dimension, and riparian buffers would be appropriate. The downstream section is more sinuous and has some riparian buffer. This portion of the project may be suitable for enhancement level II improvements.
Potential BMP Opportunities: None
99
Constraints (bridges, utilities, structures, natural areas): Few constraints are present in this project reach. Driveway road crossings and a few utility lines would have to be considered. Access is easy and little earthwork would be involved.
Potential for Improvement (water quality, hydrology, habitat): Restoration here would improve all functional aspects of the stream by reducing erosion, allowing storm flows to access a floodplain, increasing bedform diversity, and restoring a functional riparian buffer. Because of the condition of the stream and lack of riparian buffer, the potential for improvement here is excellent.
Landowner Contact: Mr. Blazer was contacted and is not interested in the program at this time. Velda Morgan (82) is elderly and in the process of selling her land. Her real estate agent was contacted (Cindy Revis, 442-0034) and they may be amenable to selling part of the property near the creek for the program. Nick Antonov (90) lives in Portland but his father and sister-in-law live on the property. Mr. Antonov was initially interested but later said that he had changed his mind and was no longer interested. Ken Myers (83) is interested in the project. Micky Hinson (88) has been noncommittal up to this point.

This site is located on Glady Fork along Upper Glady Fork Road and includes
850 feet of an unnamed tributary to Glady Fork. The mainstem flows through pastureland and mowed fields. It has been channelized and is incised. Fill dirt has been placed on the right floodplain and more material has been deposited on the banks at the upstream mainstem portion of this site (Photo 1). The mainstem is a somewhat typical restoration reach. The tributary is 850 feet long and runs through a more residential area. This stream has also been channelized and is incised. Parts of the bank have been reinforced with walls and a 300 foot section flows through a culvert. This site is contiguous with Glady Fork #2.
Riparian Vegetation:
Riparian buffers throughout this project reach are minimal and vary in width
between nonexistent and one tree wide.
Wetlands:
None
Expected Restoration Type and General Approach: Stream improvements at this site should involve restoration throughout the entire length. The 850 foot long tributary that is located in a residential area has significant constraints along with anticipated landowner requirements. These issues may make restoration on this reach unlikely. However, this reach should still be proposed because of the need. The mainstem is a more traditional restoration site. It is straightened, incised, runs through pastureland, and has a limited riparian buffer.
Potential BMP Opportunities:
105
Constraints (bridges, utilities, structures, natural areas): Constraints near this site include roads, road crossings, a culverted section of stream, an equipment staging area, a vegetable plot, and several structures. The majority of these constraints are located adjacent to the 850 foot tributary making restoration on this section unlikely. However, constraints on the remaining 1550 feet of the mainstem are few. This mainstem reach may be short but is a more typical restoration reach.
Potential for Improvement (water quality, hydrology, habitat):
Restoration here would improve all
functional aspects of the stream by restoring pattern, profile, and dimension; stabilizing the banks; allowing the stream access to its floodplain; day-lighting the stream; and enhancing the riparian buffer. Work done at this site would greatly improve the functionality of this stream.
Landowner Contact:
Charles Heron and Sue Palmer (32 and 98) are generally not interested in the
program but may be open to options. Charles and Joyce Warren (30) are not interested in the program and have a history with DOT taking their land. Katherine Davis (Don Davis Heirs 31) is not interested in the project. Contact with this landowner has been through her brother Charles Davis. He has issues about disrupting views and rights within the easement.

Expected Restoration Type and General Approach: Stream improvements at this site should include a combination of enhancement level II and restoration practices. Improvements on the shorter tributary and downstream section of the mainstem may involve just enhancement level II. Though the downstream end of the mainstem reach appears to be quite degraded, simply planting a riparian buffer may be the best solution.
However, on the upstream reaches of the mainstem full restoration practices should be
employed because of the degree of incision.
Potential BMP Opportunities: Fence cattle out of the stream.
Constraints (bridges, utilities, structures, natural areas): Several constraints are located near this site including a pond, utility lines, structures, and a well. Overall, constraints are few and should not be a great deterrent to implementing a successful project.
111
Potential for Improvement (water quality, hydrology, habitat):
Some sections on this site are in
more need of restoration than others. Restoration work at this site would improve all functional aspects of the stream by reducing erosion, allowing storm flows to access a floodplain, increasing bedform diversity, and enhancing the riparian buffer.

Preservation (ft):
This site is located on Curtis Creek along Curtis Creek Road. The upstream 350
feet is forested and is in relatively good condition. The remainder of the project is in need of more intensive restoration. The middle portion of the project reach is residential, runs through the front yards of two homes, and closely parallels Curtis Creek Road. The downstream portion flows through a mowed field.
Riparian Vegetation: The riparian buffer on the upper reach of Curtis creek varies from approximately 35 to over 60 feet wide. This buffer is in relatively good shape but may benefit from some invasive removal.
Further downstream, the buffer narrows to virtually nonexistent with only mowed grass
stabilizing the banks in most sections.
Wetlands:
None
Expected Restoration Type and General Approach:
The upstream 350 feet may benefit from
enhancement level II improvements by enhancing the riparian buffer and isolated areas of bank stabilization. The rest of the project reach should receive full scale restoration, returning a functional pattern, profile, dimension, and riparian buffer. This site would greatly benefit from restoration.
Potential BMP Opportunities:
None
Constraints (bridges, utilities, structures, natural areas): The most significant constraint at this site is the fact that the stream runs through the front yard of two homes and flows within 35 feet of Curtis Creek Road. The area around this section is mowed and carefully landscaped (Photos 2 and 3). Unfortunately,
118
this section is in the middle of the project reach and will likely pose a significant threat to the implementation of a restoration project.
Potential for Improvement (water quality, hydrology, habitat): Enhancement and restoration here would improve all functional aspects of this stream by reducing erosion, allowing storm flows to access a floodplain, increasing bedform diversity, and enhancing the riparian buffer. This project reach is in great need of restoration.

Existing Conditions:
This site is located on Beaverdam Creek along Beaverdam Road. Most of the
right bank is bordered by R. and V. Warren Farms, an old tomato farm (Photo 1). In the upstream portion, horses have direct access to the stream (Photo 3 and 4). In these areas the stream is less incised but the channel is trampled, lacks bedform diversity, and has no riparian buffer. In the downstream portion of the site the stream has been straightened, is incised, and lacks an adequate riparian buffer.
Riparian Vegetation:
The riparian buffers on this project reach vary in width between nonexistent and
one tree wide. There are short isolated areas with wider buffers. In the upstream portion where horses access the stream there is no riparian buffer. There is potential for an additional 300 feet of riparian restoration in the upstream portion where only one side of the creek is contained within the project boundary.
Wetlands:
None
Expected Restoration Type and General Approach:
Work done at this site should involve full
restoration. In most places the stream has been straightened and is incised. A functional pattern, profile, dimension, and riparian buffers should be returned to the stream.
Potential BMP Opportunities:
This site offers several opportunities for BMPs. A retention pond or
swale should be built to treat agricultural runoff from the tomato farm. Cars, equipment, and the mixing station should be removed from the bank. Livestock should be fenced out of the stream.
124
Constraints (bridges, utilities, structures, natural areas): Constraints near this site include roads, road crossings, power lines, an equipment staging area, and structures. Several greenhouses are located within 50 feet of the stream. These constraints are moderate in scope and should pose a slight threat to a successful project.
Potential for Improvement (water quality, hydrology, habitat):
Restoration here would improve all
functional aspects of the stream by restoring pattern profile, and dimension; fencing livestock out of the channel; reducing erosion; and enhancing the riparian buffer. Water quality would be further enhanced by moving the mixing station and equipment away from the stream and fencing livestock out of the streams. Restoration at this site would greatly improve the functionality of this stream.

Existing Conditions:
This site is located on Morgan Branch along Morgan Hill Road. The majority of
the site flows through pastureland and mowed fields. Livestock have access to sections of the stream. In these areas there is little to no riparian buffers and the stream is incised, unstable, and lacks bedform diversity. The remainder of the site flows through forested areas that are heavily populated with invasive species. These areas could not be inspected without trespassing. However, by viewing these reaches from the road and by looking at aerial photography it is assumed that these sections have been straightened and are incised.
Riparian Vegetation:
Riparian buffers on this project reach vary in width between nonexistent and
over 100 feet wide. The riparian buffers on more than half of the project reach are one tree width or less. Buffers are heavily populated with invasive species.
Wetlands:
None
Expected Restoration Type and General Approach: Stream improvements at this site should involve a mix of restoration and enhancement level I practices. The upstream 700 feet would benefit from restoration. Stream improvements on the downstream 2,070 feet should be in the form of enhancement level I. For the most part the stream runs through fields, so design and construction should be relatively straight forward. The downstream reach is severely incised. Constructing a bankfull bench here would involve significant grading.
Potential BMP Opportunities:
Livestock should be fenced out of the stream.
130
Constraints (bridges, utilities, structures, natural areas): Constraints near this site include roads, road crossings, and structures. These constraints may be a moderate consideration to the implementation of a successful project.

Existing Conditions: This site is located on Ballard Creek along Black Oak Cove Road. A 2,060 foot reach on Ballard Creek and a 900 foot reach on an unnamed tributary to Ballard Creek make up this project site. Ballard Creek is somewhat forested and fairly stable. Incision in the Ballard Creek reach varies from not incised to moderately incised. The unnamed tributary to Ballard Creek been straightened, runs through a field where cattle are not fenced out (Photo 3), and is piped through a culvert under Black Oak Cove Road and beyond for approximately 50 additional feet (Photo 4).
Riparian Vegetation: The riparian buffer on Ballard Creek varies from 0 to greater than 100 feet wide. The tributary has virtually no riparian buffer and flows through a cow pasture and mowed field until the last downstream 150 feet where the tributary confluences with Ballard Creek.
Wetlands:
None
Expected Restoration Type and General Approach: On the Ballard Creek reach, enhancement level II practices such as sloping banks and restoring the riparian buffer may be appropriate in the downstream sections. Preservation would be appropriate for the upstream portion of Ballard Creek. On the unnamed tributary to Ballard Creek stream improvements should involve full restoration including restoring pattern, profile, and dimension as well as planting a riparian buffer and fencing out the cattle. The stream should also be returned to daylight through the 50 foot section that is currently piped.
Potential BMP Opportunities:
Fencing out cattle from the unnamed tributary will improve water
quality.
136
Constraints (bridges, utilities, structures, natural areas): Constraints at this site include the Black Oak Cove Road crossing, several structures near the unnamed tributary, and the pond adjacent to the unnamed tributary. The pond and several of the structures are located less than 30 feet from the tributary and will likely limit restoration options. The constraints on this project site will require significant consideration.
Potential for Improvement (water quality, hydrology, habitat): Enhancement and restoration here would improve all functional aspects of the stream by reducing erosion, allowing storm flows to access a floodplain, increasing bedform diversity, keeping cattle out of the stream, and restoring a functional riparian buffer. Restoration on the tributary has a great potential for stream improvement. However, this is a short reach with many constraints. The remainder of this site is in less need of stream improvements.

Existing Conditions:
This site is located on Warren Creek and parallels Warren Creek Road. The
stream flows mostly through pastureland. No livestock were seen that had access to the creak at the time of inspection. The stream has been straightened and is somewhat incised. There is bedrock at the downstream end that holds the grade (Photo 1). A pond has recently been constructed near the stream (Photos 3 and 4).
Riparian Vegetation:
The riparian buffer in this reach varies from nonexistent to one tree wide.
Invasive plant species are present throughout the reach.
Wetlands:
None
Expected Restoration Type and General Approach: Stream improvements throughout this site should involve restoration level work. The stream has been straightened and is incised. The riparian buffer is also impaired. Improvements at this site should involve reestablishing pattern, profile, and dimension as well as enhancing the riparian buffer.
If possible, the stream should be moved away from Warren
Creek Road.
Potential BMP Opportunities:
Constraints (bridges, utilities, structures, natural areas): Several significant constraints exist on this project site. Warren Creek Road parallels the stream for approximately 500 feet and comes within 30 feet of the channel. A pond has recently been excavated next to the stream. Several structures are also
143
located near the stream and a number of driveways cross over the channel. These constraints present a moderate threat to the likelihood of a successful project.
Potential for Improvement (water quality, hydrology, habitat):
Restoration at this site has the
potential to improve all functional aspects of the stream. The channel is not terribly incised and unstable even though it appears that livestock do not have access to the stream. Therefore, the potential for improvement here is good but not great.

Existing Conditions: This site is located on the headwaters of Curtis Creek along Curtis Creek Road. The middle section of the site, below the Curtis Creek Road crossing, is incised with banks up to eight feet high. There is a headcut on this section that is approximately six feet high. The upstream and downstream reaches become more forested and less incised. It appears as if this stream originates within the identified project parcels. An investigation of the upstream extent of the stream was not conducted therefore, the length of preservation is also unknown.
Riparian Vegetation:
The riparian buffer on this reach of Curtis Creek varies greatly from 0 to over
100 feet wide. Invasives are common in the middle portion of the project site.
Wetlands:
None
Expected Restoration Type and General Approach:
The upstream and downstream sections of this
project reach are in good condition and may be suitable for preservation. The middle portion is incised, straightened, and lacks an adequate riparian buffer. Stream improvements on this portion should include restoration practices.
Potential BMP Opportunities:
Minimize sediment from adjacent gravel roads.
Constraints (bridges, utilities, structures, natural areas): Constraints at this site are considerable including roads, homes, earthwork, and utility lines. Curtis Creek Road parallels the stream frequently coming within 30 feet of the channel. Several structures are also located within 30 feet of the channel. These constraints are significant and lessen the likelihood of successful implementation.
150
Potential for Improvement (water quality, hydrology, habitat): Enhancement and restoration here would improve all functional aspects of the stream by reducing erosion, allowing stormflows to access the floodplain, increasing bedform diversity, reducing erosion, and enhancing the riparian buffer. The middle section has more potential for improvement than the rest. Overall, this site has a moderate potential for improvement.

*Depending on how the property lines are defined, this project may encompass more parcels.
Existing Conditions: This site is located on Morgan Branch and parallels South Morgan Branch Road. The stream has been moved over to the side of the valley and now comes within 40 feet of South Morgan Branch Road in places. The stream is very incised, lacks bedform diversity, and is mostly riffles (Photo 2). The channel is bordered by a mowed field on the right bank (Photo 4). Channel embeddedness was noted.
Riparian Vegetation:
The left bank, by South Morgan Branch Road, has a moderately functioning
riparian buffer. Trees are present and the buffer width varies from 40 to 100 feet. The slope from the road to the stream is very steep. On the right bank the riparian buffer is narrower varying from one tree wide to approximately 35 feet in width. Beyond this riparian buffer is a mowed grass field.
Wetlands:
None
Expected Restoration Type and General Approach:
The incision and channelization present in this
reach calls for enhancement I through adjusting pattern, dimension, and enhancing the riparian buffer. Because of the degree of incision earthwork will be a consideration at this site.
Potential BMP Opportunities: Erosion control on the steep left hillside by South Morgan Branch Road may decrease sedimentation and resulting channel embeddedness. Sediment and pollutant control from nearby dirt roads via ponds and or retention basins may also alleviate embeddedness.
157
Constraints (bridges, utilities, structures, natural areas): The largest constraint at this site is the amount of earthwork required to allow the stream access to its floodplain. However, the adjacent field offers a close location for spreading spoil. Other constraints include the proximity of South Morgan Branch Road, the Valley Market Gas Station, the Blackfoot Trail bridge, and power lines that run through the adjacent mowed field.
These constraints pose a moderate consideration when considering the
likelihood of a successful project.
Potential for Improvement (water quality, hydrology, habitat): Enhancement I here would improve all functional aspects of the stream by reducing erosion, allowing storm flows to access a floodplain, increasing bedform diversity, and restoring a functional riparian buffer.
Because of the degree of
incision at this site, the potential for improvement is good.

This site is located on South Hominy Creek and Beaverdam Creek, between
Beaverdam Road and Pisgah Road. Beaverdam Creek is a tributary to South Hominy. The South Hominy reach is on a large creek with isolated areas in need of bank stabilization (Photo 3). The aerial photograph shows an active oxbow bypass channel. The Beaverdam reach is on a smaller stream but still has a rather large drainage area of 8.15 square miles (Photo 5). This reach is incised and has established a new bankfull bench in sections.
Riparian Vegetation: The riparian buffer widths on this project reach vary between 0 and over 100 feet. There are invasive plant species growing throughout the buffers.
Wetlands:
None
Expected Restoration Type and General Approach: Stream improvements at this site should involve enhancement level II practices. There are isolated sections where the banks need to be stabilized. The riparian buffers should also be enhanced through widening, removing invasives, and planting native species.
Potential BMP Opportunities:
Constraints (bridges, utilities, structures, natural areas): Several constraints are located near this site including roads, road crossings, power lines, and structures. These constraints present a moderate threat to the likelihood of being able to implement a successful project.
163
Potential for Improvement (water quality, hydrology, habitat):
Restoration here would improve
water quality and habitat by reducing erosion and enhancing the riparian buffer. Though enhancement would benefit this stream, compared to other reaches in the watershed, this site is not in critical need of restoration. Therefore, this project has a moderate potential for functional improvements.

Existing Conditions:
This site parallels Upper Glady Fork Road at times coming within 30 feet of the
road. The stream flows through a fairly confined valley, a situation that is exasperated by the proximity of Upper Glady Fork Road. The site is contiguous with UT to South Hominy Creek #4 located directly downstream. Thus, a restoration project that pieces together adjacent landowners on both of these sites is possible. At this site, the section that is in the most need of improvement is the middle 400 feet of stream which is in pasture. The rest of the site is either less degraded or more confined.
Riparian Vegetation:
The riparian buffer on this reach varies from nonexistent to over 100 feet wide.
Invasive plant species are present throughout the site.
Wetlands:
None
Expected Restoration Type and General Approach:
Stream improvements on this site may include
enhancement level I and II practices. Restoration options are limited because of the confined valley. Enhancement level II type improvements may be appropriate for the forested areas (Photos 1 and 4) and Enhancement level I practices may be appropriate for the areas in pasture (Photos 2 and 3).
Potential BMP Opportunities:
Constraints (bridges, utilities, structures, natural areas): The major constraints on this site are the proximity of Upper Glady Fork Road and the degree of confinement in the valley. Less important constraints are the presence of several driveway crossings. These constraints pose a significant threat to the likelihood of a successful project.

Potential for Improvement (water quality, hydrology, habitat):
Improvements at this site have the
potential to enhance all functional aspects of the stream. Full restoration is not being proposed. The channel is not very incised or unstable and it appears that livestock do not have access to the stream. Therefore, the potential for improvement here is moderate.
