Dear Mr. Staub:
TRACY DAVIS
Dtrecror
The Wilmington Regional Office received a complete, modified Stormwater Management Permit
Application for Wilmington Health Associates Clinic on July 20, 2016. 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 and Session Law 2008-211. We are
forwarding modified Permit No. SW8 951014 dated July 21, 2016, for the construction,
operation and maintenance of the BMP's and built -upon area associated with the subject project.
This permit shall be effective from the date of issuance until January 2, 2022, and shall be
subject to the conditions and limitations as specified therein. Please pay special attention to the
conditions listed in this permit regarding the Operation and Maintenance of the BMP(s),
recordation of deed restrictions, certification of the BMP's, procedures for changing ownership,
transferring the permit, and renewing the permit. Failure to establish an adequate system for
operation and maintenance of the stormwater management system, to record deed restrictions, to
certify the BMP's, to transfer the permit, or to renew the permit, will result in future compliance
problems.
The following modifications are included and covered by this permit:
1. Permeable pavement has been added in the parking lot in drainage area of existing wet
pond in order to offset new built -upon area (MRI Suite Addition) on the site.
2. A permeable pavement Supplement and O&M Agreement have been provided.
3. Impervious allocations have changed and overall impervious area for the site has been
reduced.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the
right to request an adjudicatory hearing by filing a written petition with the Office of
Administrative Hearings (OAH). The written petition must conform to Chapter 150B of the
North Carolina General Statutes, and must be filed with the OAH within thirty (30) days of
receipt of this permit. You should contact the OAH with all questions regarding the filing fee (if
a filing fee is required) and/or the details of the filing process at 6714 Mail Service Center,
Raleigh, NC 27699-6714, or via telephone at 919-431-3000, or visit their website at

Stormwater Narrative
Wilmington Health Associate Clinic (WHA) — MR[ Suite Addition
Wilmington, NC
The project is located on the southwest corner of Medical Center and Canterwood Drives
in Wilmington, NC, New Hanover County, parcel ID # R06010-009-004-000, R06010-
009-008-000, R06014-005-002-000 and R06014-005-003-000. The entire site is
approximately 6.27 acres of land, of which a total of 0.3 acres is disturbed. No wetlands
exist on the project site.
The WHA — MRI Suite Addition is proposing a 1,332 sf building addition with 340 sf of
concrete area as well as replacing seventeen (17) asphalt parking spaces with pervious
concrete.
The entire site has three (3) drainage areas and is located in the Cape Fear River Basin
and drains to an unnamed tributary to Greenfield Lake; stream classification C-Sw;
stream Index Number 18-76-1. DA 1 as indicated on Sheet DI was constructed and
permitted with the State; Stormwater Permit No. SW8 951014, dated January 2, 1996
with a permit renewal, dated September 13, 2013. DA1 is treated by an existing wet
detention basin sized to collect and treat the first 1" of runoff storm and provides 90%
TSS removal. DA2 as indicated on Sheet D1 drains to an existing stormwater pond that
was not permitted as it was constructed prior to any State or City stormwater
requirements. DA3 as indicated on Sheet D1 either sheet flows or collected via closed
conduits to the City's stormwater system.
We are modifying the existing Stormwater Permit No. SW8 951014 to reduce the
permitted 77,000 sf of impervious (asphalt) area to 75,000 sf by replacing 2,667 sf of
asphalt with pervious concrete. A 75% credit of 2,000 sf is given to the 2,667 sf of
pervious concrete; therefore reducing the permitted impervious (asphalt) area to 75,000
sf. As all three (3) drainage areas within the site ultimately drain to Greenfield Lake, the
reduction in impervious area in DA1 allows/offsets the 1,332 sf of proposed building and
340 sf of proposed concrete to be constructed in DA3. Results are a reduction in
impervious surface areas for the entire site.

Dear Kelly:
We are requesting a plan revision for the above referenced permit. Enclosed please find 2 sets
of plans and the plan revision application for your review.
MedSery Management Company, LLC is proposing a 1,332 sf building expansion and 340 sf
of additional concrete. Current existing BUA totals 74,200 sf. The existing permit allows for
77,000 sf of impervious. The new addition of 1,672 sf will bring the total site BUA to 75,872
sf, allowing for 1,128 sf of future impervious area. No changes are proposed to the existing
stormwater system.
Please review for approval and contact us with any questions, comments or if you need
additional information. Thank you.

when we renew so it won't give you the detailed info you are looking for, but I wanted you to have it so you could see
that the permit is active. The second document is the "full" permit originally issued which details the info you need.

RETS Project No. 1328-16
Dear Ms. Valsi`:
RFTS is pleased to provide testing services ;during the design phase of the prol
Addition project located off Medical Center Drive in Wilmington, North
Specific site grading plans had not been provided. to us at the time this i
prepared.
DESCRIPTION OF ACTIVITIES AND FINDINGS
As requested, our staff visited the site on May 2, 2016, to perform infiltration
estimate the season a].high watertable at one location identified by.you. The
this testing was to* provide soil parameters for stormwater infiltration design.
Seasonal High Watertable Estimate

of
A hand auger boring was advanced at one location to a depth of approximately 6 172 feet
below the existing ground surface in the area proposed by the civil designer for an
infiltration structure. The encountered soilwere logged and visually classified by s depth
and a Munsell Soil Color Chart was, used to determine the hue,.value, and chrom i of the
visually distinct soil layers. Our soii7ogs are presented in Table 1.
Soils encountered in our boring consisted of interbedded clean fine sands (USCS Soil
Group "SP") through ,the boring termination depth' of 81 inches below the existing ground
surface. One exception to this generalizedcharacterization of the soil profile 'occurs
between 22 to 27 inches below the surface where a layer of.aggregate base course stone
was encountered. No distinct zones of soil cementation were encountered in the profile.
.Based on out experience with similar`soils;and comparisons pf the soil coloration to the
Mynsell Chart, it is our opinionthat seasonal high water table level, occurs approximately
56 inches below the existing ground surface. No water was encountered in the upper

68 inches. I
Infiltration Testing
Infiltration testing was performed using a model 2800 Guelph Permeameter which is a
constant -head device which operates on the Mariotte siphon principle and is referenced in
ASTM D-5126. The permeameter is used to determine field saturated hydraulic
conductivity in centimeters per second for soil at a specified depth. This testing involves
advancing a borehole to the desired infiltration depth and introducing water at a constant
head to determine the steady state flow rate from which the hydraulic conductivity can be
calculated. I
Our testing was performed approximately 14 inches below the existing ground
The results of our permeameter testing are presented in Table 2.
RECOMMENDATIONS
Based on the results of our field testing and soil classifications at the test location, we
offer the following recommendations for stormwater infiltration design:
At the test location INF-1 it is our opinion that in order to achieve the steadv state flow
rate obtained during our testing; the areas of infiltration galleries or other infiltration
structures should introduce stormwater at approximately 14 inches below the existing
ground surface elevation. For purposes of sizing the structures we recommend an
ultimate application rate of 5.9 inches per hour. These recommendations should be
reviewed by appropriate regulatory authorities before finalizing the details of any civil
design.
