PROJECT NARRATIVE
PROJECT LOCATION AND DESCRIPTION
The proposed project 163 Belvedere Street is located southeast of the intersection of David Street and Belvedere
Street. The proposed drainage plan includes a house and 3 retention ponds with a 1-foot depth.
SOIL TYPES AND GROUNDWATER ELEVATIONS
The site contains one soil group that is defined as follows by the United States Department of Agriculture
(U.S.D.A.):
· 71 – Urban land
This soil information was utilized to establish the Curve Numbers within the post development.
CURVE NUMBERS (CN)
Standard SCS procedures have been used to develop Curve Number’s (CN’s) for the post-development conditions.
POST-DEVELOPMENT STORMWATER CALCULATIONS
Based on the impervious area of the lot, a required 1,088 is to be held by the ponds. To ensure that the
supplied treatment volume meets the required treatment volume, the inground storage and the total pond
storage were calculated. Refer to the Delta Volume Calculations.
The Estimated Seasonal High Groundwater Level at this site was tested to be approximately 2 feet below the
existing ground surface. Therefore, the depth to ESHWT from the Bottom is 2 feet.

Attention: Ms. Marianne Mendenhall
Subject: Report of Groundwater Level Monitoring
163 Belvedere Street – Lot 593
Atlantic Beach, Florida
MAE Project No. 0149-0006
Dear Ms. Mendenhall:
Meskel & Associates Engineering, PLLC (MAE) has completed a groundwater level monitoring program
for the subject project. Our work was performed in general accordance with our proposal dated
November 7, 2022. The work was performed to measure the groundwater level at the site for a period of
2 months.
PROJECT INFORMATION
The site for the subject project is located at 163 Belvedere Street - Lot 593 in Atlantic Beach, Florida. The
general site location is shown on Figure 1.
FIELD EXPLORATION AND GROUNDWATER MONITORING
A piezometer was installed on November 8, 2022, at the subject property. The groundwater level was
measured approximately every 2 weeks until January 3, 2023. An aerial obtained from Google Earth,
which shows the approximate Piezometer location, is included as the Piezometer Location Plan, Figure 2.
GPS coordinates for the piezometer location were obtained from Google Earth and then uploaded to a
Garmin GPSMAP78 hands-held receiver. Prior to installing the piezometer, a utility locate request was
submitted to the Sunshine 811 call center. Once the site utilities were located or cleared, our field crew
mobilized to the site. The piezometer location, as shown on Figure 2, should be considered approximate.
AUGER BORING AND PIEZOMETER INSTALLATION
A borehole was advanced at the piezometer location to a depth of about 6 feet below the existing ground
surface. The boring was advanced using a hand-held bucket auger in general accordance with the
methodology outlined in ASTM D 1452. Representative soil samples were recovered from the boring at
1-foot intervals and returned to our laboratory for testing and classification. A summary of the field
procedures is included in Appendix A.
Once the boring was complete, a piezometer (PZ-1) was installed within the borehole. The purpose of this
piezometer was to measure fluctuations in the groundwater level over a period of two months. The
piezometer consisted of a 2-inch diameter PVC pipe string, 8 feet in length, that was installed to the
bottom of the borehole such that approximately 2 feet of pipe extended above the ground surface. The
163 Belvedere Street – Lot 593
MAE Project No. 0149-0006
Page | 2
bottom 5 feet of the pipe string was screened, while the top 3 feet consisted of solid pipe. The pipe
annulus was then backfilled with fine 20/30 sand along the 5-foot screened interval and then a bentonite
seal to the ground surface. Upon completion of the groundwater monitoring period, the piezometer was
removed, and its borehole was backfilled with soil cuttings. The location of the piezometer is included on
Figure 2, and a Piezometer Construction Log is included as an attachment to this report.
LABORATORY TESTING
Representative soil samples obtained during our field exploration were visually classified by a geotechnical
engineer using the Unified Soil Classification System (USCS) in general accordance with ASTM D 2488. A
key to the soil boring logs and a description of the soil classification system are attached to this report.
Quantitative laboratory testing was performed on selected samples of the soils encountered during the
field exploration to better define the composition of the soils encountered and to provide data for
correlation to their anticipated strength and compressibility characteristics. The laboratory testing
determined the natural moisture and organic contents, and the percent passing a U.S. No. 200 sieve
(percent fines) of selected soil samples. The results of the laboratory testing are shown in the Summary
of Laboratory Test Results included as an attachment to this report. Also, these results are shown on the
Generalized Soil Profile on Figure 3, and on the Log of Boring record at the respective depths from which
the tested samples were recovered. A summary of the laboratory test procedures is also included in as an
attachment to this report.
GENERAL SUBSURFACE CONDITIONS
General Soil Profile
Graphical presentation of the generalized subsurface conditions is presented on the Generalized Soil
Profile, Figure 3. A detailed soil boring log is also included as an attachment to this report. When
reviewing the soil profile and boring log, it should be understood that the soil conditions will vary away
from the boring location. The following table summarizes the soil conditions encountered.

Groundwater Levels
The groundwater level was measured and recorded at the time of piezometer installation, and then
measured approximately every two weeks for a period of 2 months. The measured groundwater level at
the time of piezometer installation is shown on the Generalized Soil Profile, Figure 3, and on the soil boring
log. The groundwater measurements recorded at installation and during the monitoring period are
presented on the Piezometer and Groundwater Level Measurements table, included as an attachment to

this report. It should be anticipated that the groundwater level will fluctuate seasonally and with changes
in climate.
CONCLUSION
We appreciate this opportunity to be of service as your geotechnical consultant on this phase of the
project. If you have any questions, or if we may be of any further service, please contact us.

FIELD EXPLORATION PROCEDURES
Hand Auger Boring
The auger boring(s) were performed manually by the use of a hand-held bucket auger in
general accordance with the latest revision of ASTM D 1452, “Standard Practice for Soil
Exploration and Sampling by Auger Borings.” Representative samples of the soils brought to
the ground surface by the augering process were placed in sealed containers and transported
to our laboratory, where they were examined by our engineer to verify the driller’s field
descriptions and classify the soil, and to select samples for laboratory testing.
KEY TO BORING LOGS – USCS
Soil Classification
Soil classification of samples obtained at the boring locations is based on the Unified Soil Classification System
(USCS). Coarse grained soils have more than 50% of their dry weight retained on a #200 sieve. Their principal
descriptors are: sand, cobbles and boulders. Fine grained soils have less than 50% of their dry weight retained on a
#200 sieve. They are principally described as clays if they are plastic and silts if they are slightly to non-plastic.
Major constituents may be added as modifiers and minor constituents may be added according to the relative
proportions based on grain size.

LABORATORY TEST PROCEDURES
Percent Fines Content
The percent fines or material passing the No. 200 mesh sieve of the sample tested was
determined in general accordance with the latest revision of ASTM D 1140. The percent fines
are the soil particles in the silt and clay size range.
Natural Moisture Content
The water content of the tested sample was determined in general accordance with the latest
revision of ASTM D 2216. The water content is defined as the ratio of “pore” or “free” water in
a given mass of material to the mass of solid material particles.
Organic Loss on Ignition (Percent Organics)
The organic loss on ignition or percent organic material in the sample tested was determined in
general accordance with ASTM D 2974. The percent organics is the material, expressed as a
percentage, which is burned off in a muffle furnace at 455±10 degrees Celsius.
