BACKGROUND:
Staff requests approval of SA No. 1 with Meskel to provide geotechnical and engineering services
for the Mid-Clay WRF Reclaimed Storage Tank No. 3 Project.
CCUA operates and maintains the Mid-Clay WRF, which serves the southern portion of our
service area with reclaimed water. Reclaimed water peak demand has increased, creating the need
for additional reclaimed storage capacity. CCUA Engineering staff is currently preparing the
design and construction contract documents for a 750,000-gallon reclaimed water storage tank.
Approval of this supplemental agreement will allow Meskel to perform subsurface soil
investigations and provide tank foundation design recommendations. Meskel previously provided
geotechnical services at the Mid-Clay WRF for the recent plant expansion and the potable
reclaimed pilot facility, giving them valuable knowledge of subsurface conditions at the proposed
tank site.
Meskel's proposed scope of services includes field exploration consisting of soil penetration tests
(SPTs), Including one (1) SPT to a depth of 100 feet and four (4) SPTs to a depth of 60 feet. In
addition, Meskel will evaluate the feasibility of using soil currently stockpiled at the Governor's
Park Water Treatment Plant as structural fill to support the new reclaimed storage tank at the Mid
Clay WRF. Meskel will analyze, test, and classify soil samples obtained during their field
exploration and prepare geotechnical recommendations for the tank foundation design.
The construction cost for the reclaimed storage tank will be partially funded by the $6 million
Florida Department of Environmental Protection (FDEP) grant approved by the Board of
Supervisors on November 18, 2025, as part of CCUA's reclaimed water optimization program.
BUDGET:
The 5-year Capital Improvements Plan includes $2.27 million for the Public Access Reuse Storage
Tank Improvements at the Mid-Clay WRF. After reviewing Meskel's proposal, staff determined
the proposed services fee in the amount of$24,500.00 to be fair and competitive for the scope of
work provided.
RECOMMENDATION:
Staff respectfully requests the Board of Supervisors approval of Supplemental Agreement No. 1
with Meskel & Associates Engineering, PLLC, for geotechnical and engineering services for the
Mid-Clay Water Reclamation Facility Reclaimed Storage Tank No. 3 Project,with a not-to-exceed

Subject:Revised Proposal for Geotechnical Exploration and Engineering Services
CCUA Mid-Clay WRF—Tank No. 3
Green Cove Springs, Clay County, Florida 32097
MAE Proposal No. 260034
Dear Mr. Paterniti:
MESKEL & ASSOCIATES ENGINEERING, PLLC (MAE) is pleased to present this proposal to provide the
geotechnical exploration and engineering services for the subject project. Based on your proposal request
via email on January 16, 2026, and the plan sheet provided for the "Mid-Clay Reclaimed Tank No. 3, CCUA
Project No.: 2205-084," dated November 12, 2025, we understand the project consists of installing an
additional ground storage tank at the existing Mid-Clay Wastewater Reclamation Facility(WRF), located in
Green Cove Springs, Clay County, Florida.
The proposed water storage tank will be for reclaimed-water storage and will be approximately 85 feet in
diameter. The preliminary plans propose the ground storage tank will be up to 20 feet in height and of
prestressed concrete construction. Additionally, we understand the tank will be supported on up to
approximately 6 feet of proposed infill to reach final grade within a majority of the tank footprint.
MAE has completed a Report of Geotechnical Exploration at the CCUA Mid-Clay WRF for the following
facilities and has utilized our knowledge of the subsurface conditions encountered in these explorations
to determine recommended boring depths for this proposed Tank No. 3 exploration:
• "CCUA Mid-Clay WWTF Upgrades," MAE Project No. 0146-0005, dated July 22, 2020; this
exploration included 8 SPT borings to depths of 80 to 120 feet for the proposed "Oxidation Ditch,"
as well as 3 SPT borings to a depth of 30 feet for other upgrade components, and
• "Pilot Facility at CCUA Mid-Clay WWTF," MAE Project No. 0159-0005, September 23, 2021; this
exploration included two Standard Penetration Test (SPT) borings to a depth of 25 feet for the
proposed Pilot Program building.
Furthermore, at the request of the CCUA, MAE will visit the Governor's Park WTP site to observe test pits
and obtain representative bulk samples from an existing CCUA stockpile to assess the stockpiled soil as an
import source of structural fill for the Mid-Clay WRF site. A mini excavator will be provided by CCUA for
approximately one half day to assist MAE personnel with test pits and sample collection of the stockpiled

soil. It is recommended by MAE that the test pits be performed from the top of the stockpile, where
practicable. Sampling will be performed in a manner to collect soil samples that reflect the overall
stockpile for visual classification and laboratory classification testing.
GEOTECHNICAL EXPLORATION AND ENGINEERING
The objective of the geotechnical exploration is to provide site and subsurface information to evaluate the
subsurface conditions at the site for the proposed construction. Based on the information provided, we
propose the following field services; note that boring depths have been selected based on our experience
at the project site:
Test Locations Test No. & Boring Type Test Depth
ft below ground surface
GST No. 3 5 SPT* Borings 1 X 100(center)
(85 feet in diameter) 4 X 60 (perimeter)**
CCUA Governor's Park WTP—Soil Up to 9 Test Pits*** 8 to 10
Stockpile
*Standard Penetration Test boring
**The perimeter borings are proposed to a depth of 60 feet due to clay soils encountered in other borings at the
site within a depth range of 50 to 60 feet below the ground surface.
***Mini excavator to be provided for one-half day of test pits by the CCUA
MAE will visit the site in advance of our drilling operations to stake boring locations. Based on our site
observations through available topographic survey information and Google Earth photographs, we
propose to access the site with our truck-mounted drilling equipment. We will obtain coordinates of our
final boring locations using our hand-held GPS receivers. If required, we will stake the boring locations
upon completion of our field work for the Project Surveyor to locate as part of their Survey.
We will attempt to locate existing underground utilities at the Mid-Clay site by utilizing the Sunshine State
One-Call (SSOC) system. MAE will not mobilize our equipment to the site until utilities have been located
and marked by representatives of the SSOC system. If all utilities cannot be located through SSOC and/or
CCUA, MAE recommends consideration of a private utility location service; however,we have not included
this fee herein and additional fees would apply.
Following completion of drilling, the SPT borings will be backfilled with a cement grout.
The recovered soil samples will be described in the field by the field crew. The field logs and samples will
be delivered to our laboratory, where the logs will be reviewed, and the samples classified by a
geotechnical engineer using the Unified Soil Classification System (USCS). Laboratory classification and
index property tests will be performed on selected soil samples to confirm the soil classification and
estimate engineering characteristics. In addition, one bulk soil sample will be obtained for laboratory soil
corrosion potential testing including soil pH, resistivity, chloride content and sulfate content.
A geotechnical engineer, licensed in the State of Florida, will direct the geotechnical exploration and
provide an engineering evaluation of the subsurface conditions encountered at the boring locations. The
results of the exploration and evaluation will be documented in a geotechnical engineering report that will
include the following:
• Our understanding of the planned construction;

• Recommendations for shallow foundation design parameters, including allowable bearing
capacity, subgrade modulus, and estimated settlement (total and differential) within the tank
footprint;
• Recommendations for cut, subgrade preparation, fill and compaction within the structure areas
and any special recommendations required, such as preloading, surcharging, or over-excavation;
• The results of CCUA stockpile sampling and laboratory testing, including USCS classification and
reuse evaluation;
• Recommendations on the ability to use site soils as structural fill;
• Recommendations for pipe bedding and backfill placement for the on-site utility pipelines;
• Recommendations for safe trenching methods and potential dewatering requirements within
excavation areas; and
• Recommendations for construction earthwork and Quality Control testing required during site
preparation and earthwork construction.
