9. Describe the existing conditions on the site and general land use in the vicinity of the project
at the time of this application: Steele's Mill Dam is located within Hitchcock Creek and
Page 6 of 15
consists of a 100 ft. x 15 ft. stone dam with abutments on the southern and northern sides. A
20 ft wide channel above the dam has formed and the surrounding streambanks of the former
impoundment have stabilized and become covered with dense vegetation. The project site is
bound to the north by CSX Railroad and to the west by Ledbetter Road. To the south is the
Laurel Hill Paper Company and to the east is an undeveloped area. Land use surrounding the
project site is mainly rural and agricultural The town of Cordova includes residential and
industrial areas No residences are located in the immediate vicinity of the Steele's Mill
Dam The area to the north of the site is currently zoned as "Rural Residential" and the area
to the south of the site is zoned "Village Residential." A photographic record of the site is
attached as Appendix A.
10. Describe the overall project in detail, including the type of equipment to be used: The
proposed project entails a two-phased approach Phase I includes the removal of the dam to
bedrock elevations ensuring the integrity of the structure at the project site and providing for
remnants of the dam to remain for historical purposes. As part of the demolition, boulders
extracted from the dam will be placed along the stream bank to provide additional scour
protection Phase II includes an adaptive approach to the in-stream restoration of Hitchcock
Creek through further design enhancements to allow for the passage of fish species following
the dam removal process - after morphological changes to the channel have stabilized. The
project is separated into two phases because the design of Phase II will be dependent on the
conditions of the stream bed following Phase I. A separate permit application will be
submitted at a later date for Phase 11 of this project.
Phase I of the dam removal project involves partial removal of the stone dam to bedrock
elevations using a rectangular cut approximately 15 feet high at the dam and 88 feet wide.
The sluice gate structure at the northern end of the dam is approximately 30 feet high and is
composed of a concrete frame and a wood and metal gate. This structure will also be
removed as part of Phase I. The cut will be flush with a retaining wall located along the
northern stream bank. The sluice gate is being removed to minimize future shear stress
levels across the width of the channel.
Phase I includes the demolition of approximated 610 cubic yards (CY) of stone and
concrete leaving an opening 88 feet wide at the base of the dam after removal. As part of
the demolition approximately 110 feet of stream bank and/or structures will be stabilized;
boulders extracted from the dam (approximately 285 CY of stone will be placed along the
streambank and along adjacent remaining structures to provide stabilization. Approximately
128 feet of stabilization will be placed along the right streambank and approximately 86 feet
of stabilization will be placed along the left streambank (looking downstream). Because the
quantity of sediment that has accumulated behind the dam is minimal (approximately 370
CYO the sediment will not be removed prior to removal of the dam, but will be flushed
downstream during the dam removal process. However, the removal of the dam will be
gradual and completed during periods of low flow, thus allowing for small pulses of
sediment to flow downstream instead of releasing a large sediment plume.
For Phase I construction there is no immediate access road to the project site from the
adjacent land due to the steep surrounding slopes. All access to the project site, including
Page 7 of 15
construction equipment, will be in-stream, moving upstream a distance of approximately 488
feet. Proposed construction equipment includes an excavator with either a hammer or
grapple attachment and a dump truck. The dump truck will be kept at a staging area near the
access road. The excavator will travel from the access road (point) and upstream to the
project site. Rubble from the dam demolition will be placed along both streambanks
immediately upstream of the dam (approximately 30 feet, maximum) for scour protection.
The dam will be removed during low flow conditions. If practical, demolition will occur
from 15 October through 15 March; however, if demolition activities are scheduled prior to
this period, demolition will be scheduled as close to October 15 as practical. Construction
activities during this time will minimize impacts to aquatic species. In addition, it is safer to
remove the dam during low flow conditions. Figure 4.1 depicts the topography of the area
and the plan view of the project.
11. Explain the purpose of the proposed work: The NOAA Restoration Center provides direct
project support to locally driven fisheries habitat restoration projects. The purpose for the
proposed action is to restore Hitchcock Creek to a free-flowing stream, allowing passage of
diadromous fish species from the Pee Dee River to upstream of the existing dam which is
the first impoundment of Hitchcock Creek. The dam removal would open access to
approximately 15 miles of riverine habitat in Hitchcock Creek and its tributaries. Migration
to and from spawning habitats is currently blocked by the dam for aquatic species. In
addition, Atlantic sturgeon eon (Acipenser oxyrinchus) and the federally endangered shortnose
sturgeon (Acipenser brevirostrum) have been sighted in the Pee Dee River and could
potentially use the Hitchcock Creek as habitat. Additional needs of the project area include
improving water quality conditions and ecological integrity of the watershed system.
IV. Prior Project History
If jurisdictional determinations and/or permits have been requested and/or obtained for this
project (including all prior phases of the same subdivision) in the past, please explain. Include
the USACE Action ID Number, DWQ Project Number, application date, and date permits and
certifications were issued or withdrawn. Provide photocopies of previously issued permits,
certifications or other useful information. Describe previously approved wetland, stream and
buffer impacts, along with associated mitigation (where applicable). If this is a NCDOT project,
list and describe permits issued for prior segments of the same T.I.P. project, along with
construction schedules. N/A
V. Future Project Plans
Are any future permit requests anticipated for this project? If so, describe the anticipated work,
and provide justification for the exclusion of this work from the current application.
Proposed Phase II includes an adaptive approach to the in-stream restoration of Hitchcock Creek
through further design enhancements to allow for the passage of fish species following the dam
Page 8 of 15
removal process - after morphological changes to the channel have stabilized. The design of
Phase II will be dependent on the conditions of the streambed following Phase I and will be
implemented only if both post-removal conditions indicate the streambed elevations are still
insufficient for fish passage and if funding is available. If implemented, Phase II could include
the design and construction of a rock ramp or step pools using off-site stone/materials to
facilitate flow conditions conductive for fish passage. If implemented, a subsequent permit
gpplication will be submitted at a later date for Phase II of this project.
VI. Proposed Impacts to Waters of the United States/Waters of the State
It is the applicant's (or agent's) responsibility to determine, delineate and- map all impacts to
wetlands, open water, and stream channels associated with the project. Each impact must be
listed separately in the tables below (e.g., culvert installation should be listed separately from
riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts,
permanent and temporary, must be listed, and must be labeled and clearly identifiable on an
accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial)
should be shown on a delineation map, whether or not impacts are proposed to these systems.
Wetland and stream evaluation and delineation forms should be included as appropriate.
Photographs may be included at the applicant's discretion. If this proposed impact is strictly for
wetland or stream mitigation, list and describe the impact in Section VIII below. If additional
space is needed for listing or description, please attach a separate sheet.
Provide a written description of the proposed impacts: There would be temporary aquatic
impacts from movement of construction equipment in the stream from the access point to the
dam There would be temporary increases in turbidity during demolition of the dam and
some loss of sediment upstream of the dam. The construction period is expected to last no
more than 2 months. There would be permanent fill of 0.020 acres of stream and wetlands
for bank stabilization. Debris from the dam removal would be used for fill.
There would be a permanent beneficial impact to the stream and river basin by restoring
access for diadromous fish to approximately 15 miles of Hitchcock Creek /upstream
tributaries.

VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts. The purpose of this project is
to restore Hitchcock Creek to a free-flowing stream to allow the passage of diadromous fish
species Removing the dam will open access to approximately 15 miles of riverine habitat in
Hitchcock Creek and its tributaries resulting in a net increase in aquatic resource functions and
values in the project area and Yadkin-Pee Dee River Basin.
Impacts to water quality will be minimized by the gradual removal of the dam. The removal of
the dam will be completed during periods of low flow, thus allowing for small pulses of
sediment to flow downstream. Therefore several acute and high levels of total suspended solids
(TSS) and turbidity would occur instead of one longer sediment release. The project will be
completed during low flow conditions. Construction activities during this time will minimize
impacts to aquatic species.
The long-term environmental benefit to fisheries from the removal of the Steele's Mill Dam far
outweighs short-term impacts from re-suspended sediment that will occur during demolition
of the dam. The approximate 15 miles of restored habitat is expected to transform the existing
reservoir and creek reach into a more natural creek and riparian habitat suitable for fish species,
including Federally and State listed species. As stated above, the dam will be removed during
low flow conditions to reduce adverse impacts to the aquatic environment.
The total wetland and stream impacts for the Steele's Mill Dam project have been minimized to
the extent practicable. There are no feasible alternatives to avoid the wetland and streams that
have not been considered. Access to the project site from the closest road is through the stream
channel. This is the only viable route due to the steep slopes that surround the project area.
Page 11 of 15
Construction techniques to be followed during removal of the dam include confined ingress and
egress to the same path/alignment each time the equipment is moved through the stream.
Complete avoidance of effects to Steele's Mill Dam a historic resource, would not be possible in
order to provide fish passage To minimize adverse effects to historic resources, the powerhouse
structure and retaining walls will remain in place and a historic marker will potentially be erected
documenting historic information about Steele's Mill Dam. In addition, The State of North
Carolina will continue to work with the State Historic Preservation Office (SHPO) to ensure
preservation of the historical significance of the site.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on January 15, 2002, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete.

DATE: 20 April 2007
SUBJECT: Final Environmental Assessment for Steele's Mill Dam Removal, Hitchcock Creek,
Richmond County, North Carolina, DENR Project No. 07-0310
Biologists with the North Carolina Wildlife Resources Commission (NCWRC) have reviewed the
subject document and we are familiar with the habitat values of the area. Our continents are provided in
accordance with provisions of the North Carolina Environmental Policy Act (U.S. 113A-1 through 113A-
10; 1 NCAC 25), Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661 et seq.),
and North Carolina General Statutes (G.S. 113-131 et seq.).
The National Oceanic and Atmospheric Administration Restoration Center proposes to remove
the Steele's Mill dam. The damis located on Hitchcock Creek approximately two miles upstream of the
confluence of the Pee Dee River. Plisse I involves partial removal of the dam to bedrock elevations and
no blasting will be required to remove the dam structure. Phase II, if needed, includes design and
construction of in-stream enhancement structures for fish passage such as a rock ramp or step pools.
Phase II will be implemented if after dam removal the stream bed elevations are still insufficient for fish
passage and funding is available.
The dam inhibits upstream fish passage for diadromous species such as American shad (Alosa
sapidissima), hickory shad (Alosa mediocris), striped bass (Moron saxatilis), Atlantic sturgeon
(Acipenser oxyrhynchus), shortnose sturgeon (Acipenser brevirostrum), and American eel (Anguilla
rostrata). There are records for the federal species of concern and state endangered Carolina creekshell
(lrllosa vaughaniana), the state threatened Carolina fatmucket (Lampsilis radiata conspicua) and Eastern
pondmussel (Ligumia nasuta) downstream of Steele's Mill dam. Additionally, there are records for the
federal species of concern and state endangered yellow lampmussel (Lampsilis cariosa); the federal
species ofcopcern and state significantly rare robust redhorse (Moxostoma robustum) and Carolina
redhotse (Moxostoma sp.); and the state threatened Eastern pondmussel (Ligumia nasuta), Eastern
lampmussel (Lampsilis radiata), Roanoke slabshell (Elliptio roanokensi.s), and creeper (Strophitus
undulates) in the Pee Dee River.

The proposed project will resulf in many benefits to aquatic resources in Hitchcock Creek and the
Pee-Dee River. We appreciate the initiative each agency has taken in pursuing the removal of this dam.
We will concur with the project. Although we recommend instream activities are performed between 15
October and 15 March, as detailed in our correspondence of 23 August 2006, timing instream activities to
begin as close as'possible to 15 October and completing these activities as soon as possible is preferable-
Thank you for the opportunity to provide input in the planning stages for this project. If we can
be.pf'further &-distance, please contact our office at [phone].

STATE NUMBER: 07-E-0000-0310
APPLICANT: North Carolina Department of Environment and Natural Resources
DESCRIPTION: Removal of the Steele's Mill Dam in Rockingham, Richmond County
Section 3.2.6.7 (Floodplains) of the Final Environmental Assessment Steele's Mill Dam
Removal, Hitchcock Creek, North Carolina states that "According to the Flood Insurance
Rate Maps published by Federal Emergency Management Agency (FEMA), the project
site is located in a special flood hazard area inundated by 100-year floods, also referred
to as the 100-year floodplain (FEMA 1989). The area along Hitchcock Creek is also
titled Zone A, meaning that there have been no base flood elevations determined along
Hitchcock Creek (Figure 3-6)." On November 15, 2006, FEMA and the North Carolina
Floodplain Mapping Program issued a preliminary Flood Insurance Rate Map (FIRM) for
the Yadkin River Basin portion of Richmond County that includes new flood hazard data
for Hitchcock Creek based on a limited detailed hydraulic study that includes a HEC-
RAS model. Base (100-year) Flood Elevations (BFEs) and the revised 100-year
floodplain boundary are shown on preliminary FIRM number 3710745200 J. The
floodplain is now identified as Zone AE. In the accompanying preliminary Flood
Insurance Study (FIS) report for Richmond County, Table 10 (Limited Detailed Flood
Hazard Data) provides BFEs and non-encroachment area widths at studied cross
sections along Hitchcock Creek. FEMA regulations require use of the BFE and non-
encroachment data provided on the preliminary FIRM and FIS as Best Available Data
by Richmond County in the enforcement of its Flood Damage Prevention Ordinance.
Since removal of the Steele's Mill Dam meets the National Flood Insurance Program
(NFIP) definition of development in a non-encroachment area, the proposed project
requires a floodplain development permit issued by the Richmond County Floodplain
Administrator. A condition for issuance of this permit will be either a valid No-Impact
study certified by a North Carolina licensed professional engineer or an approved
Conditional Letter of Map Revision (CLOMR) issued by FEMA.

An Equal Opportunity/Affirmative Action Employer
Section 4.1.6.7 of the Steele's Mill Dam Removal environmental assessment states that
"Although a detailed floodplain analysis has not modeled [sic], major changes in the
100-year floodplain are not expected as a result of the Proposed Action." A detailed
floodplain analysis is required according to FEMA regulations to support either No-
Impact certification or an approved CLOMR before the proposed project can be
permitted by Richmond County. The analysis is required to show the impact on BFEs,
100-year floodplain boundaries, and non-encroachment area widths upstream and
downstream of the dam location if the dam is removed. If BFEs, etc. are impacted, a
CLOMR is required to show that BFEs are not increased on any existing structures.
Within six months after the project is completed, the agency responsible for the project
must submit an application for a Letter of Map Revision (LOMR) to FEMA and the
NCFMP to document the revised BFE's, 100-year floodplain boundaries, and non-
encroachment area widths so that the FIRM is kept up to date.
Please let me know if you have any questions about this.

1. PROJECT DESCRIPTION
1.1 PROJECT BACKGROUND
The Restoration Center (RC) of the National Oceanic and Atmospheric Administration (NOAA)
Fisheries line office provides direct project support to locally driven fisheries habitat restoration
projects. The SE Region Team of the RC, in partnership with the North Carolina Division of
' Water Resources (DWR) and other agencies, is cooperatively working to restore the ecological
integrity of the Hitchcock Creek Watershed near the city of Rockingham, North Carolina. The
RC has committed to providing the design, engineering, and regulatory compliance support
' necessary to implement the removal of the Steele's Mill Dam. The State of North Carolina has
committed to undertaking (i.e., funding) the actual removal of the dam through its competitive
' bid process. The Steele's Mill Dam Project site is shown in Figure 1.
In addition to restoring the water quality and ecological integrity synonymous with an
unimpeded river, NOAA Fisheries is specifically in support of removal of Steele's Mill Dam, as
it is a barrier to habitat of important catadromouslanadromous (migratory) fisheries. Historic
records indicate that American shad and American eel inhabited Hitchcock Creek. Other
species, such as hickory shad, herring, striped bass, Atlantic sturgeon, and the federally listed
shortnose sturgeon migrate up the nearby Pee Dee River annually and potentially could utilize
' Hitchcock Creek. Some species, such as shad, have recently been observed at the base of the
dam. Removal of this dam, which is the first blockage on Hitchcock Creek, will restore passage
to approximately 15 miles of important spawning habitat for these fisheries. Additionally, other
dams on Hitchcock Creek, above Steele's Mill, are being targeted by local interests as candidates
for removal, potentially opening further access to habitat throughout the watershed-

The Steele's Mill Dam is a 100-ft x 15-ft stone gravity structure constructed in 1886, 1 mile
' upstream from the creek's confluence with the Pee Dee River. The darn was originally built to
generate power for a cotton mill, and later used for electric production. In 1999, the power-
generating facilities ceased to operate and the reservoir behind the dam was drawn down to its
' current size of 0.33 acres. Since that time, a 20-ft-wide channel above the dam has reformed and
the surrounding banks of the former impoundment have stabilized and become covered with
dense vegetation. In 2001, the Federal Energy Regulatory Commission (FERC) issued an
exemption from licensing to operate a power generating facility.
The current owner of the dam, Laurel Hill Paper Company, has expressed a willingness to
allow removal of the structure. In addition, officials from the nearby city of Rockingham,
1-1

North Carolina, and other local resource agencies are proponents of removal, as it coincides with
other watershed enhancement initiatives. 'I'o complement this project, the City of Rockingham
intends to acquire lands adjacent to the dam, develop public access, and construct a city park.
The future actions proposed by the City of Rockingham are not considered as part of this project.
' 1.2 PROJECT SCOPE
The Steele's Mill Dam Removal Project entails a two-phased approach. The first phase of the
project focuses on the removal of the dam to bedrock elevations; ensuring the integrity of
structures within close proximity to the project site; and providing for remnants of the dam to
' remain for historical purposes. As part of the demolition, boulders extracted from the dam will
either be placed along the stream bank to provide scour protection.
' The second phase of the project entails an adaptive approach to restoration of the creek through
further design enhancement to allow for fish passage following demolition of the dam. Post-
removal evaluations will assess the need for further channel modifications to facilitate fish
passage after changes to the channel have stabilized.
' This Design Analysis Report describes the field investigations and technical basis for the darn
removal design. Specific tasks include:
' • e survey and base mapping
' • Hydrologic and hydraulic modeling
• Design documents
' Previous work performed at the site by EA Engineering, Science, and Technology included a
Phase I Environmental Site Assessment submitted to NOAA in January 2005, a Sediment
Quality Assessment submitted to NOAA in March 2005, a Draft Conceptual Design submitted to
NOAA in November 2005, and a Draft Final Design in December 2005_

2. TECHNICAL APPROACH
2.1 FIELD SURVEYS AND BASE MAPPING
The dam and site around the dam were surveyed in October 2004 utilizing fast static GPS to
provide a base map for design and construction of the dam removal. The survey also serves a
basis for the hydrologic and hydraulic (H&H) modeling- The base map created from the survey
is provided as Figure 1.
The survey was tied to local benchmarks and defines the dam structure in three dimensions,
providing enough data to produce a plan view, elevation view, and cross-sections through the
dam. The survey area included topography and other distinct site features relevant to the
feasibility of the dam removal. Cross-sections through the creek provided the information
' required for the H&H modeling.
' In addition to conducting the survey, sediment depths were measured at 23 locations upstream
(Figure 1) in order to estimate the total volume of sediment deposited behind the dam. The
depths were measured by pushing a steel probe into the sediment until the probe could not be
' pushed further, known as refusal. It is assumed that refusal occurred because the probe had
reached the elevation of the original creek bottom. The depths of the sediment ranged from
approximately 0.1 ft (approximately 1 in. on the north side of the stream bed) to approximately
4 ft (on the south side of the stream bed approximately 20 ft upstream of the dam). Results of
the volume calculations indicated that approximately 370 cubic yards of sediments are located
within a 6,050-ft2 area upstream of the dam.
2.2 HYDROLOGIC AND HYDRAULIC ANALYSIS
Steele's Mill Dam is located in Cordova, North Carolina, in the Lower Pee Dee Watershed.
i Hitchcock Creek is the largest tributary below the Blewett Falls Dam on the Pee Dee River. The
McKenney Lake National Fish Hatchery and the Sand Hills State Game Lands are located within
' the Hitchcock Watershed. As part of the dam removal study and design (phase I of the project),
a detailed hydrologic and hydraulic study was completed to determine current and proposed flow
regimes at the project site. For this study, the project team evaluated storm (2- and I0-year) and
' flood flow (I00-year) events under current conditions and a number of alternatives. Low flow
fish passage conditions were not evaluated as part of this study, and will be addressed after more
data from field gages are collected, specifically data for the spring flows/migration season in
2006.

2.2.1 Hydrology
The drainage area to the Steele's Mill Dam is 140.68 square miles. The topography of
the watershed is fairly hilly, especially in the upper reaches- The elevation ranges from
approximately 500 ft NGVD in the upper portion of the watershed to 125 ft downstream
of the dam.
To assess both present and proposed conditions at the project site, the North Carolina Regional
Regression Equations were used. Steele's Mill is in a rural area of North Carolina in the Blue
Ridge Piedmont hydrologic region. To determine the 2-, 10-, and 100-year peak discharges,
the following equations, provided by the U.S. Geological Survey, were used:
Q2 = 135Ao.702
Qia = 334A 0.662
Q. 745A°125
-
-
Knowing that the drainage area `A' of Steele's Mill Dam is 140.68 square miles, the peak
discharges `QT' are 4,349, 8,828.3, and 16,398.4 cfs for the 2-, 10-, and 100-year events,
respectively. These values were entered into HEC-RAS as upstream flows for the portion
of Hitchcock Creek being studied.
2.2.2 Hydraulics
To evaluate the removal of the Steele's Mill Dam, a hydraulic computer model was created for
Hitchcock Creek for approximately 700 ft upstream of the dam and 200 ft downstream of the
dam. The model was used to estimate existing and proposed flow depths, velocities, shear stress,
and water surface profiles-
For the existing conditions model, ArcGIS was used to view existing contour lines and the
stream centerline. Cross-sections were cut every 50-100 ft upstream and downstream of the dam
and approximately every 10 fl within the immediate vicinity of the dam. HEC-GeoRAS was
then used to translate these into the stream profile and cross-sections in HEC-RAS_ Figure 2
shows the locations of the HEC-RAS cross-sections and the corresponding river station
identifications.

In HEC-RAS, the Steele's Mill Dam was inserted as an inline structure with the top of the dam
at an elevation of 138.5 ft. The sluice gate was input into the structure as fully open while the
power plant flow-through was considered closed.
The existing conditions model was run with the above flows. All three storm events are shown
' to overtop the dam in the HEC-RAS model with the maximum shear stress in the channel
occurring during the 100-year event at 13 lb/ft" while both-banks had a maximum shear stress of
approximately 0.95 lb/ft2. The stream profile is provided iri Figure 3, The model output for the
existing conditions is summarized in Table 1(A) and is detailed in Appendix A (Table A-I).
' For the proposed conditions, the cross sections in the existing model were modified to reflect the
removal of Steele's Mill Darn for two scenarios (the Conceptual Design and the Modified
Conceptual Design). The first scenario (Conceptual Design) involves removing the center
r section of the dam with a trapezoidal cut, leaving the powerhouse and the sluice gate in place but
closed. This scenario was depicted in the Conceptual Design dated November 2005. The second
scenario (Modified Conceptual Design) involves a rectangular removal of the dam, extending
from the powerhouse to the retaining wall as depicted in the Draft Final Design dated December
' 2005.
The model output for the Conceptual Design (first scenario) is summarized in Table I (B) and
' detailed in Appendix A (Table A-2). The shear stress in the channel increases from the existing
conditions (approximately 13 lb/ft2) to approximately 65 lb/ftz - a 500 percent increase over the
existing condition. This is due to the steep slope of the bedrock left behind when the dam is
removed and the contraction of water through the dam opening. The anticipated channel profile
is shown in Figure 4. The removal of the dam creates a hydraulic jump under proposed
' conditions- This means the Energy Grade line (EGL) is steeper for the Conceptual Design and
the shear stresses on the banks are greater. It is important to note that the elevations for the creek
profile beneath the dam were assumed because no investigations were performed beneath the
dam and as-built conditions are not known. If a flatter creek profile exists beneath the dam,
lower shear stresses in the channel would be expected post-removal. The maximum shear stress
' on the banks is approximately 0.9 lb/ft2 for the 100-yr storm as shown in Table 1(B)_ The
Modified Andrews Equation for shear stress calculations (Schlindwein 2003) was applied to
determine the size of stone needed to protect the banks- This equation yielded a median stone
' diameter of approximately 1.1 ft to protect the banks from scour during the 100-yr storm event.
' The model output for the Modified Conceptual Design (second scenario) is summarized in Table
I (C) and detailed in Appendix A (Table A-3). The channel shear stress for this scenario is also
2-3
r
1

higher than the existing conditions -- 28 lb/ft2 or a 215 percent increase over the existing
conditions for the 100-yr storm event. The maximum bank shear stress is 0.3 lb/ft2, which
requires a stone approximately 0.75 ft in median diameter to protect the banks from scour during
a 100-yr storm event. Stone this size most likely can be placed from the remnants of the
removed dam. The stream profile for this scenario is provided in Figure 5.

Cross-sections with water surface elevations for the existing conditions and the two proposed
scenarios described above are also included in Appendix A.
2.2.3 Low Flow Hydrology and Hydraulics for Fish Passage

This section will be further addressed after the migration season of 2006. The project team
installed two stream gages, one barometric gage, and a rain gage, to collect targeted flow
information for the specific purpose of fish passage design efforts. The project team has been
downloading the information on a regular basis, except for a short period of time after which the
' gages were vandalized and required replacement. To date, no further vandalism issues have
occurred, and the team will continue to monitor the flow information until late June 2006_ From
the information collected, the project team will provide hydrology and hydrar?lic conditions of
the system, such as stream power and stress, velocity, stage, and temperature, as well as a more
accurate indication of spring base flow conditions to create a more accurate tailwater rating curve
' for the purpose of designing a step pool or rock ramp structure, if determined to be necessary
after the Steele's Mill Dam is removed.

2.3 CONSTRUCTION DESIGN
The following sections describe the design basis in more detail and discuss the permitting
requirements for the project.
' 2.3.1 Construction Plans and Bid Documents
' A conceptual design was prepared for the partial dam removal and submitted to NOAA for
review and comment on 2 November 2005. NOAA responded verbally with comments on 22
' November 2005. The conceptual design included removal of the center section of the dam with
a trapezoidal cut, leaving the powerhouse and the sluice gate in place but closed.
' Subsequently, a draft final design was submitted in December 2005. In the draft final
submission, the design was modified to incorporate the results from the hydrologic/hydraulic

2.3.2 Cost Estimate
A construction cost estimate was prepared with the design and is included in Appendix B. The
job was estimated by assuming daily costs for crew and equipment to perform the demolition.
A separate line item cost for hauling and disposal of unsuitable material was also included to
account for the removal and disposal of undersized rubble, wood, or metal encountered during
demolition It is recommended that the job be bid as a lump sum item for the dam removal with
a separate line item for hauling and disposal of unsuitable material. This provides some
flexibility in the contracting since the darn core material is unknown and total quantity of
unsuitable material is unknown. The estimated cost to complete the project is $222,600.
