The fill impact listed is for possible replacement of an existing sanitary sewer pipe crossing that is partially exposed In the stream bed It will be placed
at the same location and elevation as the existing pipe, so it is only "fill" in relation to removal of the old pipe The temporary impact is for putting
equipment within the stream bed to remove a large concrete pier The actual pier removal (excavation) only affects 10 -12' of stream length, but the
work areas for the pier removal and the sewer replacement could extend as much as 40 to 50 feet each

Narrative for Pre - Construction Notification
Revolution Mill Bridge Removals and Sanitary Sewer Replacement
The Revolution Mill site was developed prior to 1900 and was one of the major textile mill sites in
Greensboro, a part of the overall Cone Mills enterprise. Two of the historic buildings straddle North
Buffalo Creek, at a point where the contributing drainage area is roughly 15 square miles. A multi-
million dollar site redevelopment effort was initiated in 2003 to convert the former mill buildings to a
mix of commercial and residential uses, primarily office space. An aerial view of the Revolution Mills site
is shown in Figure 1. As part of the redevelopment of the site, and also to enhance conveyance of floods
through the property, the owners intend to remove all or portions of five abandoned bridge crossings on
the site. The purpose of this pre- construction notification is to obtain authorization for very limited
potential temporary impacts within the stream channel associated with the bridge removals and
rehabilitation or replacement of an existing sanitary sewer pipe slightly exposed above the bed of the
stream. The bridges have all been abandoned for some time and the removal of these structures will
improve flood conveyance through the site. The bridge decks are deteriorated and /or partially missing.
All of the removal work for the bridge decks will be accomplished using equipment working from the
stream banks. These structures are referenced as numbers 1 to 5 on the attached plan sheet, with
markups for the contractor on what will be removed and how the removals are to be done. The
following descriptions relate to plans for removal work of the bridge piers. The references to left and
right are when one is facing downstream.
Structure 1 — There are no stream impacts associated with this demolition. All of the piers to be
removed are up on the left bank of the creek well above the ordinary high water mark (last 3 piers at the
far end of the photo below).
Narrative for Revolution Mill PCN 1 AWE"
ENGINEERING CONSULTANTS. PC

Structure 2 —The site owners are hoping to retain all or part of this structure, dependent on the
outcome of a request to FEMA for a Conditional Letter of Map Revision. However, if they opt for
removal, they plan to demo and remove only the portion of the pier which is above the concrete base
footing. The contractor will plan to place concrete median barrier or some other type of barrier along
the edge of the concrete base to prevent concrete from falling into the stream bed as the removal is
being accomplished.
Narrative for Revolution Mill PCN 2 AWELL
ENGINEERING CONSULTANTS. PC

Structure 3 —The contractor expects that the piers in the stream bed were built such that they can be
"rocked" loose from the underlying bedrock and lifted out with equipment working from the adjacent
bank. No discharges or use of equipment within the stream channel is proposed.
Narrative for Revolution Mill PCN 3 AWBU
ENGINEERING CONSULTANTS. PC

Structure 4 — This bridge is built on wooden piers, which are proposed to be sawed off at the stream bed
level. No discharges or use of construction equipment is proposed within the stream channel, with the
exception of an individual operating an underwater saw.
Narrative for Revolution Mill PCN 4 gown"
ENGINEERING CONSULTANTS. PC

Structure 5 — There is a single concrete pier under this bridge. Although the contractor expects that it
can be "rocked" loose from the stream bed, they are not confident that it can be pulled out of the
stream because it is so large. There is a possibility that they will need to use equipment within the
stream channel to complete the removal. In that case, they plan to place a concrete barrier around the
work area in order to divert the channel flows to the other side of the stream. This removal work is
listed on the PCN form as a temporary stream impact.

Sanitary Sewer Pipe Replacement — There is an existing 12" ( ?) ductile iron sanitary sewer pipe partially
exposed above the stream bed. It was taken out of use by previous property owners because of
problems with leaks, reportedly at an adjacent manhole. The applicant /owners plan to repair or replace
that manhole and also the existing sewer pipe. The owners will coordinate plans with the City of
Greensboro to discharge to their existing sanitary sewer main on the south (right) side of North Buffalo
Creek. The contractor will either temporarily dam the creek to facilitate a pump- around, or will replace
the pipe in sections, working in half of the stream bed at a time while diverting flows around the work
area.

Additional Proposed Site Work in Vicinity of North Buffalo Creek
No Proposed Impacts to Jurisdictional Waters
New Dock Access at Building A
As with the removal of Structures 1 to 4, there are no impacts to jurisdictional waters expected with this
work, but it will occur in an area immediately adjacent to the overbank area of North Buffalo Creek so
we are including the information with the PCN. The structure pictured below will be removed, with the
intent that piers be completely removed and not just sawed off at ground level. That access ramp to the
dock along Building A will be replaced with one at the same elevation as the dock, which will be bolted
to the building on one end with the other end atop a support foundation in the parking area. The area
beneath will be an open span, with the existing retaining wall to be repaired /replaced to the extent
necessary.
New Pedestrian Bridge
The site plan submitted to the City of Greensboro includes plans for construction of a new pedestrian
bridge just upstream of Building I. The bridge deck will completely span North Buffalo Creek at an
elevation at least a foot above the effective 100 -year FEMA flood elevations. There will be bridge
supports constructed within the stream buffer area under authorization to be obtained from the City of
Greensboro.
