Re: PCN for Lower Longview Lake Dam Repairs, Raleigh, Wake County ( Neuse River basin).
Dear David,
Attached is the PCN (NWP -3) for the City of Raleigh's proposed repairs to Lower Longview
Lake Dam on an unnamed tributary of Crabtree Creek, two miles east of downtown Raleigh. I
discussed the project with Jamie Shern in 2011, and based on that conversation he agreed the
work could be permitted under Section 404 Nationwide Permit 3 for repair and maintenance.
Let me know if you'd like to arrange a site visit to confirm this. DWQ staff visited the site with
me in 2011, when we determined that the abandoned channel (original stream) below the dam
is not subject to Neuse riparian buffers.
The road across the dam crest (Albemarle Avenue) has been closed since 2008 due to the poor
condition of the dam and its spillway culvert which serves as a bridge. The project will include
the following much - needed structural and safety improvements to the dam and street: 1) widen
the dam footprint to reduce the slopes of both the upstream and downstream faces; 2) replace
the inadequate culvert spillway with a new dropbox riser, twin culverts through the base of the
dam, and stilling pool below the dam; 3) raise the dam crest about three feet to prevent
overtopping during major storms; and 4) widen the street to meet City standards and provide a
sidewalk. The project as described herein, designed by Schnabel Engineering of Greensboro,
will include the following unavoidable impacts to wetlands, streams, open waters (lake), and
riparian buffers:

The State Historic Preservation Office (SHPO) sent a scoping response letter stating that the
dam is within Longview Gardens Historic District, which was listed in the National Register of
Historic Places in 2011. SHPO requested site photos and plans for the reconstructed dam and
road, and confirmation that the house to be demolished is not within the Historic District.

3. Project Description
3a. Describe the existing conditions on the site and general land use in the vicinity of the project at time of this application:
Lower Longview Dam was built in the 1950s in the Longview Gardens neighborhood, on an unnamed tributary about 1900 feet
upstream of its confluence with Crabtree Creek. The dam has a drainage area of 1.1 square miles, and impounds about 8 acres
at normal pool level. Albemarle Ave runs along the crest of the dam, but has been closed to traffic since 2009 due to the poor
structural condition of the culvert containing the spillway. Twenty residential properties border the lake, and several others
border the creek below the lake. Milburnie Rd crosses this creek about 450 feet northeast (downstream) of Lower Longview
Dam. Upper Longview Dam, which impounds a smaller lake upstream, is about 1400 feet west of Lower Longview Dam.
Lower Longview Dam is approximately 20 to 25 feet tall and 550 feet long, with a crest elevation (road surface) ranging from
206 feet (lowest point near middle of dam ) to 210 feet (SE end of dam directly above spillway). The spillway crest elevation in
the culvert beneath the road is approximately 201 feet, which is the normal pool elevation. The streambed elevation below the
toe of the dam is approximately 183 feet. Elevations provided above are referenced to the North American Vertical Datum of
1988 (NAVD88). The downstream embankment slope is steep (1.5H:1 V and steeper in some areas) and the upstream slope has
a shallow failure mass near the center of the dam. Both the upstream and downstream slopes of the dam are vegetated with
brush and trees (many trees larger than 6 inches diameter). The existing principal spillway is a concrete box culvert, 15.8 feet
wide by 7.5 feet tall, with concrete sidewalls and a steel and timber- framed roof which serves as a bridge for Albemarle Ave. A
3 -inch diameter natural gas pipeline and an 8 -inch diameter water pipeline are located within the roadway and are suspended
below the culvert roof . The culvert inlet sill and much of the culvert floor is bedrock, and additional bedrock downstream of
the culvert forms a 150 -foot long step -pool cascade that drops 18 feet to the sand/gravel creek bed below the dam.
The receiving stream below the bedrock cascade is perennial, generally 10 to 15 feet wide, with sand, gravel and bedrock
comprising the bed materials. Crayfish, mayfly and caddisfly larvae, sunfish, creek chubs and other small fish were observed by
RJG &A during field surveys in February 2011. A muddy channel 140 feet long and 10 to 16 feet wide is located west of the
stream and joins the stream 220 feet north of the spillway culvert. This sparsely- vegetated channel is the remains of the original
(abandoned) stream prior to dam construction, and is now characterized as a linear wetland. It receives minor leakage from the
lake's clogged drainpipe, seepage from under the dam, and runoff or seepage from adjacent uplands.
3b. List the total estimated acreage of all existing wetlands on the property:
The only wetland in the project area is the abandoned stream channel on the floodplain northeast of the dam and west of the
active stream channel. It is approximately 140 feet long and 10 to 16 feet wide, with an area of 2000 sq.ft (0.046 acre). It is
sparsely vegetated with a few wetland herbs, vines and small shrubs in the muddy channel bed, and larger shrubs and trees
rooted on the non - wetland banks. The prevalence of soft silty mud and decomposing leaf litter indicates that it rarely conveys
significant flow above the channel bed. The lake shoreline near the dam supports a narrow fringe (1 to 4 ft wide) of typical
marsh herbs and shrubs, but these areas are within the normal lake pool and counted as open waters rather than wetlands. There
may be additional wetlands along the upper lake shoreline beyond the project construction area; these areas were not examined.
Page 3 of 12
PCN Form — Version 1.3, Dec 2008

3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
The stream channel from the spillway culvert outlet at Albemarle Ave to the culvert inlet at Milbumie Rd is approximately 500
feet long. The upper 150 feet beginning at the culvert outlet is a bedrock cascade flowing over former uplands (not the natural
channel) and below that it joins the low - gradient natural channel. Most of this stream is on parcel #1724014398, except the
lowermost 50 ft near Milbumie Rd, which is on a residential lot beyond the project construction area. This stream is mapped on
both the USGS Topographic Quadrangle (Raleigh East) and the USDA Soil Survey of Wake County (Sheet 59).
3d. Explain the purpose of the proposed project:
Dam safety inspection has revealed that Lower Longview Dam and spillway are in serious need of repair. Albermarle Ave
along the dam crest has been closed to traffic since 2009 due to the poor condition of the road and spillway culvert roof which
serves as a bridge for this road. The dam and spillway will be repaired and upgraded to meet current NC Dam Safety Act
standards for a high - hazard dam. Trees will be removed from both dam slopes, and fill added to create a wider footprint and
flatter slope of 3H:1 V. The new dam crest will be 36 feet wide to meet Raleigh street standards (with curb, gutter and
sidewalk). The finished grade low point elevation will be approximately 209 feet, or three feet higher than the existing road
surface low point. The old spillway culvert will be demolished and filled in, and a 1 -foot diameter pipe installed to maintain
normal baseflow in the existing perennial stream. A new concrete drop box spillway inlet will be built near the middle of the
dam to convey storm flows greater than the 1 -ft pipe's capacity, with twin culverts installed through the dam, and a stilling basin
discharging to the old stream channel below the dam. The drop box and culverts are sized to pass the design storm without
overtopping the dam, and the stilling basin will provide non - erosive flow velocity in the receiving stream. The lake's normal
pool elevation will remain approximately the same at about 201 feet, but the lake surface area will be slightly reduced due to
extension of the upstream slope. The project will maintain consistency with the City of Raleigh's Lake Preservation Policy.
3e. Describe the overall project in detail, including the type of equipment to be used:
Construction work will be performed in three stages, described below. Other tasks involving demolition and construction of
utility lines, signs, driveways, and other structures that do not affect waters or riparian buffers are not described here.
Stage 1: Install a temporary siphon pipe through the culvert spillway to drain the lake. Base flow and storm flow will be
conveyed through the old culvert spillway (elevation 201 ft) during Stage 1 construction. Install the erosion and sedimentation
control measures. Excavate sediment and woody debris along the upstream slope of the dam and adjacent lake bed, and
construct the Stage 1 coffer dam (earth fill and geogrid) to dewater the proposed construction areas for the drop box spillway
and upstream slope grading. Construct a second, smaller coffer dam across the former stream channel (wetland) downstream of
the proposed stilling basin. Excavate the lake bed and a trench through the central portion of the dam down to residual soil
foundation, remove the old clogged drain pipe, and construct the new drop box riser, twin culverts through the dam with filter
drainage and diaphragm, and stilling basin below the dam. The drop box riser will have a 25 x 40 ft footprint, a bottom drain
outlet at 188 ft elevation, a 20 -ft long front spillway at 201.6 ft, and two 35 -ft long side spillways at 206.3 ft. Backfill the trench
over the new culverts and riser, then complete the Stage 1 grading on the center and left portions of the upstream dam
embankment up to 208 ft elevation. Place riprap on the upstream slope between 196 and 206 ft elevation. Remove the Stage 1
cofferdams and siphon.
Stage 2: Construct the Stage 2 coffer dam in the lake around the existing culvert spillway area, and a rock check dam across the
creek below the bedrock cascade (180 ft downstream of the old culvert). Pass storm flows through the bottom drain outlet on the
new drop box riser. Demolish and remove the existing spillway bridge and culvert, and clear, grub and excavate the
downstream dam slope as required to install the drainage structures. Clean the bedrock downstream of the culvert, apply
concrete to achieve proper grade for the new base flow spillway pipe, and install the concrete pipe (1 ft diameter, approximately
130 ft long) with inlet and outlet headwalls. The pipe inlet elevation in the lake will be the same as the old culvert spillway (201
ft) and the outlet will be at 194 ft elevation, located about 55 ft downstream of the old culvert outlet (to accommodate the fill
required to widen the downstream dam slope). The exposed sewerline along the right bank below the culvert will also be
encased in concrete. Build a reinforced concrete toe wall (68 ft long) just above and parallel to the left bank of the stream,
downstream of the baseflow spillway pipe outlet, at the proposed toe of the expanded dam. Backfill the old spillway over the
new baseflow pipe, and grade the remaining upstream and downstream portions of the dam embankment. Place riprap on the
upstream slope between 196 and 206 ft elevation to match the central and left upstream portions. Seed all exposed soil areas on
both slope with groundcover appropriate for dam embankments.

PCN Form — Version 1.3, Dec 2008

3e. continued:
Stage 3: Remove the Stage 2 cofferdam and reconfigure the stream diversion to convey base flow through the new pipe
spillway. The lake can now begin to refill, and storm flow will pass through both the concrete pipe spillway and the new riser.
Install stormwater collection and drainage features for the road and downstream slope of the dam, with riprap extending 3 feet
beyond the toe of slope below the downstream storm drain outlets. Install new utility lines (water, gas, electric) on the dam
crest, build up the embankment to the design sub -base elevations for the road, then complete fine grading and paving of
Albemarle Ave (209 to 211 ft elevation) and the new sidewalk. Remove the erosion and sediment control devices after
permanent vegetation is established.

acre. Fill in the lake is required to widen the dam embankment slope to 3:1 for dam safety purposes. The permanent lake fill (0.410 acre)
includes 0.225 acre of pool area reduction (fill extending above 201') and 0.185 acre of lake bed made shallower. The lake will be
temporarily drained during dam repair, and the sediment thus dewatered prior to removal.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
Page 7 of 12
PCN Form — Version 1.3, Dec 2008

1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The downstream dam face must be extended to meet current safety requirements, so it is not possible to avoid the small wetland at the toe
of the dam or the 58 -ft segment of stream below the old culvert. The stilling basin outlet will match the grade of the natural receiving
stream below. The toe wall along the left stream bank will avoid the need to relocate or pipe the perennial stream. Open water impacts
within the lake will be mostly temporary (dewatering, cofferdam, excavation and backfill) except that the lake surface area will decrease
by 0.22 acre. The new drop box riser and fill required to broaden the upstream dam slope are unavoidable, but will have minor adverse
impact on aquatic life or neighborhood use of the lake. The riprap along this slope will provide habitat structure for juvenile fish and other
aquatic life.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Temporary cofferdams and bypass piping will keep the work area dewatered to minimize erosion, turbidity, and potential concrete
toxicity. Erosion and sediment controls and flow bypassing will ensure minimal damage and adequate flow to the stream below the dam
during construction. Trees must be permanently excluded from the dam embankment by periodic mowing, but all areas of the dam
embankment that do not require concrete or riprap for stability will be kept vegetated to enhance stormwater infiltration.

Habitat?
US -FWS and NC -NHP online lists of federal endangered species reported from Wake County include Dwarf Wedgemussel,
Red - cockaded Woodpecker, and Michaux's Sumac. No suitable habitat for these species exists in or adjacent to the project
area, based on field surveys by RJG &A in February 2011 and June 2013. Habitats in the project area have been fragmented and
isolated by urban development for 50+ years, and it is unlikely that any of these species could persist in or colonize this site.
6. Essential Fish Habitat (Corps Requirement)
6a. Will this project occur in or near an area designated as essential fish habitat?
❑ Yes ® No
6b. What data sources did you use to determine whether your site would impact Essential Fish Habitat?
NC -DMF and NC -WRC have not designated any Essential Fish Habitat in the Crabtree Creek watershed.
7. Historic or Prehistoric Cultural Resources (Corps Requirement)
7a. Will this project occur in or near an area that the state, federal or tribal governments have
designated as having historic or cultural preservation status (e.g., National Historic Trust
® Yes ❑ No
designation or properties significant in North Carolina history and archaeology)?
7b. What data sources did you use to determine whether your site would impact historic or archeological resources?
Lower Longview Lake Dam is located within the Longview Gardens Historic District, which was listed in the National Register
of Historic Places in 2011. SHPO requested site photos and plans for the reconstructed dam-and road, and confirmation that the
house to be demolished is not within the Historic District. Photos, plans and requested information are being sent to SHPO.
SHPO also replied that it is unlikely that any archaeological resources would be affected, and no archaeological survey is
needed.

PCN Form — Version 1.3, Dec 2008

8. Flood Zone Designation (Corps Requirement)
8a. Will this project occur in a FEMA- designated 100 -year floodplain?
® Yes ❑ No
8b. If yes, explain how project meets FEMA requirements:
The new spillway was sized to match the flow characteristics of the existing structure, with the upper spillway on the dropbox
riser at 206.3 feet elevation. Schnabel Engineering has prepared a No -Rise Certification Letter based on HEC -RAS modeling
which shows a "no -rise" condition. The project will not affect the FEMA 100 -yr flood elevation upstream or downstream.
8c. What source(s) did you use to make the floodplain determination? Wake County FIRM Panel #1724 (May 2006, viewed on
www.ncfloodmaps.com) indicates a 100 -yr flood elevation of 201 feet (zone AE) extending from Crabtree Creek upstream to
Lower Longview Dam. The FIRM Panel does not indicate a flood elevation upstream of the dam.

Instructions for completion of worksheet (located on page 2): Begin by determining the most appropriate ecoregion based on
location, terrain, vegetation, stream classification, etc. Every characteristic must be scored using the same ecoregion. Assign points
to each characteristic within the range shown for the ecoregion. Page 3 provides a brief description of how to review the
c haracteri sties identified in the worksheet. Scores should reflect an overall assessment of the stream reach under evaluation. 11,0
characteristic cannot be evaluated due to site or weather conditions, enter 0 in the scoring box and provide an explanation in the
comment section. Where there are obvious changes in the character of a stream under review (e.g., the stream flows from a pasture
into a forest), the stream may be divided into smaller reaches that display more continuity, and a separate form used to evaluate each
reach. The total score assigned to a stream reach must range between 0 and 100, with a score of 100 representing a stream of the
highest quality.
Evaluator's Signature ,t�� 9�O.tw__ Date 0 dune 2013
This channel evaluation onrm is intended to be used only as a guide to assist landowners and environmental professionals in
gathering the data required by the United States Army Corps of Engineers to make a preliminary assessment of stream
quality. The total score resulting from the completion of this form is subject to USACE approval and does not imply a
particular mitigation ratio or requirement. Form subject to change - version 06/03. To Comment, please call 919 - 876 -8441 x 26.

Re: Lower Longview Dam Rehabilitation, Raleigh, Wake County, ER 13 -1130
Dear Mr. Pottern:
Office of Archives and History
Deputy Secretary Kevin Cherry
Thank you for your letter of June 11, 2013, concerning the above project, which proposes: demolition of the
existing Albemarle Avenue bridge,' demolition of the sidewalls and headwalls on the east side of the dam,
demolition of one single - family house downstream of the dam, widening the existing dam footprint, and
constructing a new outlet structure.
There are no known archaeological sites within the proposed project area. Based on our knowledge of the
area, it is unlikely that any archaeological resources that may be eligible for inclusion in the National Register of
Historic Places will be affected by the project. We, therefore, recommend that no archaeological investigation
be conducted in connection with this project.
The lake, dam, and bridge are located within the Longview Gardens Historic District, which was listed in the
National Register of Historic Places in 2011. Before we can comment on the proposed undertaking, please
forward photographs showing the existing dam, headwalls, sidewalls, bridge, outlet structures, and the house to
be demolished. Also include a site plan showing the existing and proposed conditions. Will a new bridge be
constructed, or will Albemarle Avenue be disconnected permanently?
Please verify that the house to be demolished is 2541 Albemarle Avenue; this house is located outside of the
historic district.
The above comments are made pursuant to Section 106 of the National Historic Preservation Act and the
Advisory Council on Historic Preservation's Regulations for Compliance with Section 106 codified at 36 CFR
Part 800.
Location 109 Fast Jones Street, Raleigh NC 27601 Mailing Address 4617 Mail Service Center, Raleigh NC 27699 -4617 Telephone /Fax (919) 807 - 6570/807 -6599

Thank you for your cooperation and consideration. If you have questions concerning the above comment,
contact Renee Gledhill- Earley, environmental review coordinator, at 919- 807 -6579 or renee.gledhill-

Re: Lower Longview Lake Dam Repairs, Raleigh, Wake County (ER 13- 1130).
Dear Renee,
Thank you for your comment letter (July 16) on the Lower Longview Lake Dam repair project, -
located two miles east of downtown Raleigh on an unnamed tributary of Crabtree Creek. We
offer the following responses to your questions:
" The lake, dam, and bridge are located within the Longview Gardens Historic District, which was
listed in the National Register of Historic Places in 2011. Before we can comment on the proposed
undertaking, please forward photographs showing the existing dam, headwalls, sidewalls, bridge,
outlet structures, and the house to be demolished. Also include a site plan showing the existing and
proposed conditions."
Response: Project plans and photographs of the dam and house are attached, as requested in
your comment letter. The dam is overgrown with trees and vines and there is not much
.structure" to be seen in the photographs, except for the culvert. The house to be demolished at
2541 Albemarle Avenue is a single - family split -foyer style residence, built in 1968 according to
Wake County tax records (iMaps website). As stated in your letter, this house is located outside
of the historic district.
" Will a new bridge be constructed, or will Albemarle Avenue be disconnected permanently? "
Yes, Albemarle Ave will be rebuilt along the crest of the repaired dam, on its current alignment
and 2 to 3 feet higher than the existing road. The new road will be a few feet wider and will
include a sidewalk, which the current road does not.
Feel free to email or call, me if you have any further questions or comments about this project
and its impacts to the Longview Gardens Historic District.
Sincerely,
A41;6RAZ7
