Re: Express review of Stormwater BMP of Metropolitan I
Dear Joseph,
Please find attached as per your email of February 9, 2009 the following:
1. A check for $1,000.00
2. Storm water Application form in 1 Original and 2 Copies
Which includes also the breakdown of Impervious Surfaces.
3. One Metropolitan I Erosion Control plan which has the full site + the requested
delineation of the Drainage Area Attributed to the BMP. Since there are multiple
delineations, there is a legend on the drawing that explain the used symbols. This is sheet
# 10. In 3 copies
4. Sheet 13, BMP details, Calculations, cross sections, details of the structures, planting,
maintenance access ( partly shown in drawing and the rest described I nthe notes on the
lower right had side.
5. 1 have also included excerpts of the Dr. Barrett L. Kays soils related findings, I could not
locate Dr. Hargett's Report that was jointly paid by the state and me, it should be in the
file, which more details, pictures, etc.
6. I have also included the grading plan. sheet # 15 which has the required fencing for the
Riparian buffer as well as other undisturbed buffers.
7. The letter from EEP
Please note that there may be a retaining wall of 5 ft max along the 30' phase 1 buffer north of
the BMP (continuation of the existing retaining wall), that decision will be made during the
grading of the project, this we would ask to be placed in the letter you would write, we would
need to provide Cary with changes if needed, such change does not effect the BMP or storm
water plan. Please kindly look over the application, if you would see something is missing, or
needs amendment, please let me know ahead of time, before proceeding with the express review.
Looking forward to your kind reply.
Sincerely

Stormwater Wetland 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:
- Immediately after the stormwater wetland is established, the wetland plants will
be watered twice weekly if needed until the plants become established
(commonly six weeks).
- No portion of the stormwater wetland will be fertilized after the first initial
fertilization that is required to establish the wetland plants.
- Stable groundcover will be maintained in the drainage area to reduce the
sediment load to the wet detention basin.
- Once a year, a dam safety expert will inspect the embankment.
After the wet detention pond is established, I will inspect it once a month 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.

The stream flow on September 24, 2003 exceeded the monthly mean flows for the winter
and spring. Therefore, if the subject stream is in fact intermittent, and has flow in the
winter and spring as defined in the Rule, it should have flow on September 24, 2003.
However, the author's field inspection determined that no flow was present in the stream
on the subject property.
On-Site Evaluation of Water Table
A hand auger boring using a 2.75-inch open bucket soil auger was conducted approximately 3 to
5 feet back from the stream channel, but within the alluvial/colluvial deposits along the stream
channel. Location of investigations is shown on Map #1. The soil profile at Location #1
consisted of the following:
A-horizon: 0 to 12 inches: Dark brown (10YR 4/3) loam, wet soil moisture condition.
conditionhorizon: 12 to18 inches:
con Pale brown (10YR 6/3) loamy sand, moist soil moisture
.
C-horizon: 18 to 60 inches: Variegated (2.5 YR 5/8) and (5 YR 7/3) silt loam, saprolite,
moist to dry soil moisture condition, boring terminated at 60 inches, soil was dry from 20
to 60 inches, no water table within 3.0 feet below the stream channel.
Approximate Surface Elevation: 438 feet above MSL (based upon Town of Cary
topographic map)
Approximate Water Table Elevation: 400 feet above MSL (based upon off-site
determination of water table)
Stream Channel. Approximately 1 inch of standing water, no discernible flow in the
channel or seepage into the channel was present. The water was determined to be
remnant of the stormwater runoff from the rainfall the day prior to the inspection.

to 48 inches, no water table within 2.5 feet below the stream channel.
Approximate Surface Elevation: 432 feet above MSL (based upon Town of Cary
topographic map)
Approximate Water Table Elevation. 400 feet above MSL (based upon off-site
determination of water table)
Stream Channel: Approximately 2 inch of standing water; no discernible flow in channel
or seepage into the channel was present. The water was determined to be remnant of
the stormwater runoff from the rainfall the day prior to the inspection.
Stream Flow: No stream flow was present
Geology/Groundwater Evaluation
The location of the investigation is shown on Map #1. The geologic map of the area is shown on
Map #2. The geology/groundwater evaluation at Location #3 consisted of the following:
The geology and groundwater discharge was evaluated at the confluence of a stream
approximately 740 feet downstream of the subject property. The geologic unit consisted
of Big Lake-Raven Rock schist 1. No springs, seepage, water, or flow was found
between Maynard Road and Location #3.
25
The geology/groundwater evaluation at Location #4 consisted of the following:
The geology and groundwater discharge was evaluated downstream of Gregory Drive
and approximately 1,250 feet downstream of the subject property. The geologic unit
consisted of Big Lake-Raven Rock schist 1. Springs and seepage of water was noticed
coming from an apparent quartz dike at Location #4. The stream channel had
approximately 0.1 cfs flow.
The geology/groundwater evaluation at Location #5 consisted of the following:
The geology and groundwater discharge was evaluated after the confluence with the east
branch of Black Creek, approximately 2,080 feet downstream of the subject property and
just upstream of Maynard Road. The geologic unit consisted of Big Lake-Raven Rock
schist 1. The east branch of Black Creek is running parallel to contact with Sycamore
Lake greenstone unit. The stream channel had approximately 1 cfs flow.
The geology/groundwater evaluation at Location #6 consisted of the following:
The geology and groundwater discharge was evaluated at the downstream of Maynard
Road on the east branch of Black Creek and approximately 2,880 feet downstream of the
subject property. The geologic unit consisted of Sycamore Lake greenstone unit. This
unit is considered to be well fractured and contains good flow rates. The stream channel
had approximately 2 cfs or more flow. Downstream of this location the stream flow
increases appreciably due to the greenstone unit.
Based upon the off-site geologic/hydrologic analysis the groundwater seepage into the stream at
Location #4 occurs at approximately 394 to 396 feet above MSL. Therefore, the water surface
elevation under the subject property should be approximately 400 feet above MSL and
approximately over 30 feet below the elevation of the bottom of the stream channel.
Map #3 shows my assessment of the stream order based upon the Strahler system. Typically 1St
Order streams in the Piedmont region of North Carolina are ephemeral streams. The Soil Survey
of Wake County North Carolina also shows the stream on the subject property as 15t Order.
Soil Survey of Wake County North Carolina
The soil survey was used to evaluate the approximate trend in water table depths. The soil
survey does not contain site specific information. However, it can be useful to determine general
relationships. The Worsham soil shown along the stream on the property is shown to have a
seasonally high water table to the surface, although in this case it determined to be a perched
seasonal water table. The Cecil soils shown on each side slope adjacent to the stream is shown
to have a seasonally high water table of 10+ feet below the surface. Based upon the authors
experience in the general area, the water table under Cecil soils frequently is as much as 50 feet
or more below the surface. Therefore, it is quite reasonable for the water table and seasonal high
water table to be considerably below the bottom of the 1st order stream channels in this area.
Analysis of Documents
The perennial streams as shown on the United State Geological Survey 7.5 Minute topographic
map of the Cary Quadrangle are illustrated on Map #4. Portions of the east branch and a portion
of the west branch of Black Creek are shown as perennial as well as the main stem of Black
Creek.

The stream flow on September 24, 2003 exceeded the monthly mean flows for the winter
and spring. Therefore, if the subject stream is in fact intermittent, and has flow in the
winter and spring as defined in the Rule, it should have flow on September 24, 2003.
However, the author's field inspection determined that no flow was present in the stream
on the subject property.
On-Site Evaluation of Water Table
A hand auger boring using a 2.75-inch open bucket soil auger was conducted approximately 3 to
5 feet back from the stream channel, but within the alluvial/colluvial deposits along the stream
channel. Location of investigations is shown on Map #1. The soil profile at Location #1
consisted of the following:
A-horizon: 0 to 12 inches: Dark brown (10YR 4/3) loam, wet soil moisture condition.
AC-horizon: 12 to18 inches: Pale brown (10YR 6/3) loamy sand, moist soil moisture
condition.
C-horizon: 18 to 60 inches: Variegated (2.5 YR 5/8) and (5 YR 7/3) silt loam, saprolite,
moist to dry soil moisture condition, boring terminated at 60 inches, soil was dry from 20
to 60 inches, no water table within 3.0 feet below the stream channel.
Approximate Surface Elevation: 438 feet above MSL (based upon Town of Cary
topographic map)
Approximate Water Table Elevation: 400 feet above MSL (based upon off-site
determination of water table)
Stream Channel: Approximately 1 inch of standing water; no discernible flow in the
channel or seepage into the channel was present. The water was determined to be
remnant of the stormwater runoff from the rainfall the day prior to the inspection.

AC-horizon; 14 to18 inches: Brown (10 YR 5/3) gravelly loamy sand, moist soil moisture
condition.
C-horizon; 18 to 48 inches: Variegated (2.5 YR 5/8) and (5 YR 7/3) silt loam, saprolite,
moist to dry soil moisture condition, boring terminated at 48 inches, soil was dry from 24
to 48 inches, no water table within 2.5 feet below the stream channel.
Approximate Surface Elevation: 432 feet above MSL (based upon Town of Cary
topographic map)
Approximate Water Table Elevation: 400 feet above MSL (based upon off-site
determination of water table)
Stream Channel: Approximately 2 inch of standing water; no discernible flow in channel
or seepage into the channel was present. The water was determined to be remnant of
the stormwater runoff from the rainfall the day prior to the inspection.
Stream Flow: No stream flow was present.
Geology/Groundwater Evaluation
The location of the investigation is shown on Map #1. The geologic map of the area is shown on
Map #2. The geology/groundwater evaluation at Location #3 consisted of the following:
The geology and groundwater discharge was evaluated at the confluence of a stream
approximately 740 feet downstream of the subject property. The geologic unit consisted
of Big Lake-Raven Rock schist 1. No springs, seepage, water, or flow was found
between Maynard Road and Location #3.
25
The geology/groundwater evaluation at Location #4 consisted of the following:
The geology and groundwater discharge was evaluated downstream of Gregory Drive
and approximately 1,250 feet downstream of the subject property. The geologic unit
consisted of Big Lake-Raven Rock schist 1. Springs and seepage of water was noticed
coming from an apparent quartz dike at Location #4. The stream channel had
approximately 0.1 cfs flow.
The geology/groundwater evaluation at Location #5 consisted of the following:
The geology and groundwater discharge was evaluated after the confluence with the east
branch of Black Creek, approximately 2,080 feet downstream of the subject property and
just upstream of Maynard Road. The geologic unit consisted of Big Lake-Raven Rock
schist 1. The east branch of Black Creek is running parallel to contact with Sycamore
Lake greenstone unit. The stream channel had approximately 1 cfs flow.
The geology/groundwater evaluation at Location #6 consisted of the following:
The geology and groundwater discharge was evaluated at the downstream of Maynard
Road on the east branch of Black Creek and approximately 2,880 feet downstream of the
subject property. The geologic unit consisted of Sycamore Lake greenstone unit. This
unit is considered to be well fractured and contains good flow rates. The stream channel
had approximately 2 cfs or more flow. Downstream of this location the stream flow
increases appreciably due to the greenstone unit.
Based upon the off-site geologic/hydrologic analysis the groundwater seepage into the stream at
Location #4 occurs at approximately 394 to 396 feet above MSL. Therefore, the water surface
elevation under the subject property should be approximately 400 feet above MSL and
approximately over 30 feet below the elevation of the bottom of the stream channel.
Map #3 shows my assessment of the stream order based upon the Strahler system. Typically 1St
Order streams in the Piedmont region of North Carolina are ephemeral streams. The Soil Survey
of Wake County North Carolina also shows the stream on the subject property as 1St Order.
Soil Survey of Wake County North Carolina
The soil survey was used to evaluate the approximate trend in water table depths. The soil
survey does not contain site specific information. However, it can be useful to determine general
relationships. The Worsham soil shown along the stream on the property is shown to have a
seasonally high water table to the surface, although in this case it determined to be a perched
seasonal water table. The Cecil soils shown on each side slope adjacent to the stream is shown
to have a seasonally high water table of 10+ feet below the surface. Based upon the authors
experience in the general area, the water table under Cecil soils frequently is as much as 50 feet
or more below the surface. Therefore, it is quite reasonable for the water table and seasonal high
water table to be considerably below the bottom of the 1St order stream channels in this area.
Analysis of Documents
The perennial streams as shown on the United State Geological Survey 7.5 Minute topographic
map of the Cary Quadrangle are illustrated on Map #4. Portions of the east branch and a portion
of the west branch of Black Creek are shown as perennial as well as the main stem of Black
Creek.

Stormwater Wetland Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log ir- 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.
Impo rtant maintenance procedures:
- Immediately after the stormwater wetland is established, the wetland plants will
be watered twice weekly if needed until the plants become established
(commonly six weeks).
- No portion of the stormwater wetland will be fertilized after the first initial
fertilization that is required to establish the wetland plants.
- Stable groundcover will be maintained in the drainage area to reduce the
sediment load to the wet detention basin.
- Once a year, a dam safety expert will inspect the embankment.
After the wet detention pond is established, I will inspect it once a month 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.
