Please see the attached proposed Deed Restriction as executed by my client„
regarding the Infiltration Trench Operation and Maintenance Agreement.
My client has also signed said Agreement, and please find that attached as well.
There are currently no deed restrictions or covenants recorded reflecting this
Agreement, and may not be for some time, or at least until said project plat is properly
subdivided and recorded. My client agrees to incorporate this Infiltration Trench
Operation and Maintenance Agreement in the proposed Deed Restriction (attached) and
record same at the time the project is properly platted and recorded, and/or at the time
when the Master Declaration is recorded.
My client further agrees to include this Agreement as an Exhibit to said
Declaration if required. Please let me know if you require anything further from our

Infiltration Trench Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity of
structures, safety of the public, and the removal efficiency of the BMP.
Important maintenance procedures:
R The drainage area of the infiltration trench will be carefully managed to reduce
the sediment load to the sand filter.
R The water level in the monitoring wells will be recorded once a month and after
every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal County).
The infiltration trench will be inspected once a quarter and within 24 hours after every
storm event greater than 1.0 inches (or 1.5 inches if in a Coastal County). Records of
operation and maintenance will be kept in a known set location and will be available
upon request.
Inspection activities shall be performed as follows. Any problems that are found shall be
repaired immediately.

Dear Ms. Karoly:
The following are our responses to your request for additional information dated 10-14-08.
1. After completing the level spreader supplement form for this project level spreaders cannot be
used because of the slope of the receiving buffer. An 18" cross pipe has been added to divert the
stormwater from both sides of the shared driveway into the infiltration trench.
2. Infiltration trench design information submitted.
Please find the additional information sufficient for your continued review and approval for the
referenced project. Please contact me if you have any questions.

RE: Saturated Hydraulic Conducs* Testing for potential Stormwater Infiltration
Trench on the MoGuinn Subdivisoin in northern Wake County.
Dear Mr. Stewart:
Central Carolina Sol Consulting conducted field analysis of the saturated hydraulic
conductivity of the saprolte for the proposed stormwater infiltration trench on the
McGuinn site per your request. The requested saturated hydraulic conductivity tests
were required to determine the hydraulic conductivity of the soltseprolite for a
stomwa ter best management practice (BMP) device system (Infiltration trench). The
soiVsite evaluation was performed with hand auger borings and a compact constant
head permeameter (Amoozemeter) under moist soil conditions, based on the criteria
found in the user manual provided by Ksat, Inc. The minknum hydraulic conductivity
required for sofa utilizing an infiftration trench is 0.52 inches/hour per the NCDENR
Stormwater BMP Manuel (Chapter 16). Please note that CCSC only recorded the
hydraulic conductivity analysis once the soillseprolite In each test zone was under
saturated conditions. This form of hydraulic conductivity is not required via the
aF I I , - I entioned Stormwater Mermel and is considered a more conservative technique
to the determft the hydraulic conductivity of a particular soil type and/or horizon.
The site investigation was conducted on May 23, 2008 at which time one area was identified
that consisted of suitable soils/ssprolibe to potentially support the proposed infiltration trench.
The proposed area is shown on the attached map. The soil in the proposed area is similar to
the Cecil sol series with a day textured subsoil extending to approximately 35 inches below
the surface. Underlying the subsoil was coarse textured (sandy loam) C horizon (saprolite).
Central Carolina Soil Consulting pedbn ned four hydraulic conductivity (Ksat) measurements at
representable locations within the saprolite. The results of which are attached to this report.
The saturated hydraulic conductivity tests were performed in order to recommend an infiltration
rate for the trench bottom of the BMP device. Based on the average results of the saturated
hydraulic conductivity test CCSC recommends that the maximum design infiltration rate not to
exceed 0.60 indresfiour, provided the top 40 inches of naturally occurring soil is removed or
the majority of the device is installed below the existing 40 inch grade so that the device is
installed into the highly permeable saprolite within this area. Indications of a seasonally high
MAY=30-2008 07:16 FROM:CENTRAL. CAROLINA SDI 19197949079 70:3631477 P.2
water table were observed at approximately 70 inches below the existing grade. Therefore the
lower treatment zone should be designed not to exceed 70 inches.
Central Carolina Soll Consulting, PLLC is a professional consulting firm lizing in
soil delineations, design for on-side wastewater dial systems and saturmated
hydraulic c wWudiv4 analysis. The rules govemingi ori4de wastewater disposal
systems are complex and the interpretation of the rules are based upon the opinions of
regulators (state and county !even. Due to the suave nature of the peg
process and the vadabildy of naturally occurring soft, CCSC cannot guarantee that
areas delineated as suitable for w"Re wastewater disposal systems andibr saturated
hydraulic condw%vi<y anaMft results will be Permitted by the governif 9 veencies.
These permitting considerations should betaken into account before a financial
commitment is made on a trail of land.
if you have any questions regarding the findings on the attached map or in this report,
please feel free contact me at anytime. Thank you allowing Central Carolina Soil
Consulting to perform this she evaluation for you.
