proposed project:
2b. Water Quality Classification of nearest receiving water: C, NSW
2c. River basin: Neuse
3. Project Description
3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this
application:
A portion of the site is the home of the existing Cherry Hospital (NC mental hospital) serving eastern NC. The majority of
the site is undeveloped. The proposed impacts occurs adjacent to an existing sanitary sewer easement maintained by
the City of Goldsboro.
3b. List the total estimated acreage of all existing wetlands on the property:
Unknown (the entire 1,230 acre tract has not been delineated)
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
Unknown (the entire 1,230 acre tract has not been delineated)
3d. Explain the purpose of the proposed project:
The project consists of a proposed 12-inch aerial santiary sewer crossing which will replace an existing 8-inch aerial
sanitary sewer crossing. The proposed aerial crossing will be located in a 30-inch steel carrier pipe for additional
protection (the existing sewer crossing is not located in a carrier pipe).
3e. Describe the overall project in detail, including the type of equipment to be used:
The proposed 12-inch aerial santiary sewer crossing will replace an existing 8-inch aerial sanitary sewer crossing. The
proposed aerial crossing will be encased in a steel carrier pipe (the existing sewer crossing is not protected). There are
two proposed piers to support the aerial crossing and will replace the existing five (5) piers currently located in the stream.
One of the proposed piers will be located on solid ground within the Neuse Buffer. The second proposed pier will be
located in the stream but away from the main channel. Traditional construction equipment will be utilized including
excavators, drill rigs, and bulldozers. The pier to be located in the stream channel will be installed utilizing a micropile
foundation which will allow the use of a much smaller piece of construction equipment.
4. Jurisdictional Determinations

Corps or State been requested or obtained for this property / ? Yes ? No ® Unknown
project (including all prior phases) in the past?

removed are approximately 1'-6" by 2'-0" (15 SF), therefore a reduction in permanent impacts is expected. Rip rap will be
installed along the stream banks to account for the remaining permanent stream impacts. In order to construct the proposed
pier, a temporary 35' by 35' (1,225 SF) platform will be constructed in the river to support the construction equipment. Once
the pier has been constructed, this temporary platform will be removed.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
During the design phase, we attempted to design a support system which could span the entire river. This would require a
carrier pipe approximately 90 LF without supports. In order to span this distance, a stainless steel carrier pipe approximately 2
inches thick would be required which would be extremely cost prohibitive. In addition, a ful size crane would be needed to
install the pipe and access for this equipment would have created enen more impacts. The foundations required for the piers
are to be installed utilzing micropiles in lieu of driven H piles. The micropiles utilize a smaller drill rig than the traditional H pile
rig. The mircopiles are more costly to construct but access to the site is easier and reduces the impacts to the stream and
buffers. Because the proposed aerial crossing connects to an existing pump station located approximately 200 feet away,
there was no opportunity to design the pipe to go below the stream.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
The micropile rig is a much smaller piece of construction equipment as compared to the traditional deep foundation pile rig. In
order to access the site with a traditional deep foundation pile rig, additional impacts would have been required along with a
larger work platform in the river.
