Pavilion - Onslow Memorial Hospital
The Wilmington Regional Office received a complete Stormwater Management Permit
Application for ER & Surgical Services Pavilion on August 3, 2006. Staff review of the plans
and specifications has determined that the project, as proposed, will comply with the,
Stormwater Regulations set forth in Title 15A NCAC 2H.1000. We are forwarding Permit No.
SW8 950317 Modification dated August 3, 2006, for the construction of the subject project.
This permit modifies Permit No. SW8 950317, issued May 28, 1996, by: (a) changing the
Owner/Signing Official to Mr. Daniel T. Waller, Senior Vice President; (b) revising the permit to
incorporate development of a high density pocket in an overall 30% low density development;
and (c) adding a wet detention pond for the treatment of the increase in built -upon area of
169,771 square feet caused by the subject project.
This permit shall be effective from the date of issuance until August 3, 2016, and shall be
subject to the conditions and limitations as specified therein. Please pay special attention to
the Operation and Maintenance requirements In this permit. Failure to establish an adequate
system for operation and maintenance of the stormwater management system will result in
future compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have
the right to request an adjudicatory hearing upon written request within sixty (60) days
following receipt of this permit. This request must be in the form of a written petition,

Stan,
The last item to clarify is the drawdown calculation for the pond. You used a
Manning Pipe Calculator instead of the orifice equation. A 3" orifice results in
a 1.1 day drawdown using the orifice equation and a 2" orifice results in 2.4 days.
Use Q, cfs = 0.0438 * C * (d 1 )Z * (h)1/2
where C = dischg coef = 0.61
d 1 = orifice diam, inches
h = differential head at orifice, ft = ((TP elev - PP elev)/2) - ((d 1 /12)/2)
Q = 0.075 cfs for a 2" orifice & drawdown of the design volume is in 2.4 days. (see
attached spreadsheet)

Onslow Memorial Hospital
Jacksonville, NC
1 Introduction
' This report presents the findings of a pre -development and post -development stormwater
evaluation for a proposed expansion of Onslow Memorial Hospital (OMH) to be located
behind the existing hospital facility along Western Boulevard in Jacksonville, North
1 Carolina. This study is intended to assure that the proposed stormwater facilities are of
adequate size to handle the anticipated flows after development with no surcharging of
pipelines or overflowing of channels.
1 This evaluation follows the guidelines set forth by the City of Jacksonville Engineering
Department and by the North Carolina Department of Environment and Natural
Resources (NCDENR).
Data Gathering
A topographic survey was completed for the proposed hospital expansion. Currently, the
hospital consists of a main building (OMH), maintenance buildings, mental health
buildings, helicopter pad, sidewalks, paved patios, minor connector roads, and parking
lots. The western part of the hospital is the proposed area of improvements. The
proposed site consists of 54.88 total acres with portions of that containing impervious
surfaces and open space.
Conclusion
Drainage area 91 drains to a drainage ditch on the north side of White Street and flows
toward Western Blvd. There will be an insignificant decrease in the drainage area and
will not require any qualitative controls.
Drainage area 92 drains to the drainage ditch on the northwest side of the project site.
Impervious area from pre -development to post -development will grow from 2.64 acres to
6.54 acres. This increase will be treated by the ronsxuction of the proposed detention
pond. The pond will treat the 1.0" storm and will be designed as a wet pond to reduce the
total suspended solids by 90%. The overflow will drain through the outlet structure and
into the existing drainage ditch behind the basin.
Drainage area #3 also drains into a drainage ditch on the northwest side of the project
site. The drainage area will be reduced due to the increase in drainage area 42 and will
not require any qualitative controls. Drainage area #2 and 43 will join as they currently
do and discharge the stormwater from the site.

PROJECT NARRATIVE
ER & Surgical Services Pavilion — Onslow Memorial Hospital
The existing site is 54.88 acres and contains the main hospital building, medical office
buildings, helipad, parking lots and sidewalks. The proposed project is to add a new
emergency room and surgery center. The footprint of the proposed building is
approximately 85,000 sf and will be located over an existing parking lot. Several new parking
lots are proposed around the perimeter of the new building along with the relocation of the
helipad, one parking lot and the existing roadway behind the building. A proposed
construction sequence is included. The proposed parking lots are to be built first because
the building construction will eliminate most of the employee parking.
The existing site does contain jurisdictional wetlands in the northwest corner of the property
that will not be impacted by this project. The US Army Corps of Engineers approval is
included. The location of the existing swales will hydraulically separate the proposed basin
from the wetlands. Storm water runoff will be decreased or remain the same in most areas
of the site. Drainage area 2 will provide the only increase due to the increase in impervious
area. Calculations have been completed to show that the proposed detention basin will
control the increased runoff from this drainage area for the 1 inch storm and will provide an
overflow structure along with an emergency spillway for storms in excess of the design
storm. Rip -rap is proposed at all of the discharge points to provide sedimentation and
erosion control.
The City of Jacksonville has issued the sediment and erosion control permit for this project
which provides drainage swales to promote overland flow along with temporary sediment
traps to ensure that the receiving ditches and swales will not be impacted by the construction
of this project.

Mr. Sugg:
My answers are numbered the same as your questions.
1. Section .1008 (9)(2) pertains to the longitudinal slope of a curb outlet swale.
Perhaps you are referring to .1008 (h)(2) which is the design criteria for
alternative measures? Wet detention ponds, exfiltration trenches and infiltration
basins are not considered alternative measures, so they are designed using a design
storm for high density projects which is simply just the runoff from a 1" rainfall.
Whether that 1" rain falls in 15 minutes or 24 hours, makes no difference. High
density measures must be designed to store and treat the runoff from 1" of rain
(i.e., first flush). For projects within 1/2 mile of SA waters, the volume
requirement is increased to 1.511.
2. 85% TSS is the only quality control that the State of NC has at the moment. By
following the design criteria for Wet detention bains, infiltration, sand filters,
and bio-retention basins as listed in the BMP Manual, all of these measures will
provide a minimum of 85% TSS removal. vegetated filters are required at the outlet
from all of these measures, except for a pond designed with additional surface area
to remove 90% TSS.
3. I don't know anything about your site, so I am unable to assist in determining
what is the most suitable measure. If a high density project (i.e., >30%) is more
than 1/2 mile from SA waters, wet detention is the most common stormwater measure
chosen. However, if your site has suitable soils and a deep water table, use of
infiltration or bio-retention is completely permisible. For high density sites
(i.e., >25%) within 1/2 mile of SA waters, infiltration is the only option allowed.
4. 1 see no problem with a stormwater control system located remotely from the
development as long as adequate drainage to the system is provided. The Division
encourages projects to plan for future development by locating and sizing the
control to account for the future development.
5. For high density sites, use of catch basins, piping, ponds, curb cuts, etc., is
commonly used, as long as all devices direct runoff into the treatment system.
Under low density, hard -piped collection systems are not allowed -only sheet flow
and grassed swales.

Ms. Lewis,
I'm working with Stan Fortier on this project and I was asked to review the
requirements that you sent to him. I called you earlier today but thought I
would send you an email so you would have my questions in written form also. I
have reviewed the "EHNR-T15A: 02H.1000" and have the following question:
1) What design year and intensity storm do we need to design for? I see in
section .1008 g (2) "the post development discharge rate shall be no larger than
predevelopment discharge rate for the one year 24 hour storm." Does this mean we
just need to make sure the pre and post development discharge is the same for
the one year, 24 hour storm only?
2) Are there any quality controls other than the 85% TSS that we need to be

Re: Onslow Memorial Hospital
aware of for design?
3) Do you have a preference on which type of control system you think is best
for our site? We were rolling around the idea of long (500') vegetative ditches
that may drain to a detention pond. Another idea was to try to have as much
overland(sheet) flow as possible. Any reasons you feel better or worst about
either idea?
4) we are trying to design for the Hospitals long term design so we may place
the possible detention system a good distance from the current building to be
properly place for future build out. Is there any reason you see this as a
problem?
5) We hope to us a system of catch basins in parking lots, curb cuts, grass
swales, ditches and detention pond. Are there any problems that come to mind
with the use of these items for the site?
Thank you for your time and consideration on this matter.
