AGENDA ITEM: Evaluation of Options for Irrigation for Selva Marina Country Club
Golf Course
SUBMITTED BY: Jim Han ,
DATE: January 22, 2013
STRATEGIC PLAN LINK: Golf Course
BACKGROUND: Financial difficulties and possible sale of the Selva Marina Golf Course was
brought to the City Commission's attention several months ago. The
Commission expressed concerns about possible future uses of the property
which may have included dense residential or commercial development that
could have overwhelmed the capacity of adjacent streets, devalued adjacent
properties and created other problems. The Commission authorized staff to get
proposals from qualified consultants to evaluate possible public ownership and
operation of the golf course. More recently, representatives from the Country
Club indicated that their loan had been refinanced to provide more time to plan
for the long term continued operation of the golf course as a private country
club. However, they asked for the assistance from the City of Atlantic Beach
to find long term solutions for the irrigation problems resulting from the use of
brackish water from the Selva Marina lagoon system.
The City subsequently authorized J. Collins Engineering Associates to look
into the possible alternatives for irrigation on the golf course. These included
both the possibility of using wells and the additional treatment required to
provide wastewater effluent for reuse at the golf course. The study for this
project is now completed and will be presented by Utility Director Donna
Kaluzniak at the City Commission meeting on January 281n
BUDGET: Capital costs for the construction of reuse facilities range from approximately
$450,000 to $744,000 and 20 year operational costs for each option are also
estimated in the attached report (See page 14). If the City decides to move
ahead with the project for reuse, appropriate rate(s) should be adopted for reuse
cost to recover a portion of the expense of treating the reuse water to meet all
appropriate state and federal standards.
RECOMMENDATION: This report is being made to the City Commission to provide status of this
project. No decisions are requested at this point.

SECTION 1.0 - INTRODUCTION
1.1 - Purpose
The Selva Marina Country Club (SMCC) is seeking alternate options for a
feasible long term irrigation water supply for the golf course. Current irrigation
source is onsite storm water ponds and Sherman Creek, but the water supply is
inadequate during periods of the year and has a high concentration of dissolved
solids or salts. Over the last few years, SMCC has had the potential for
development of additional housing unit and golf course upgrades. The plan for
development has included the options of wells as a new supplemental water
supply. In addition, the City of Atlantic Beach (COAB) previously conducted an
analysis of upgrading Wastewater Treatment Facility #1 (WWTP #1) to provide
reuse.
This irrigation evaluation study described within includes an assessment of two
water supply options: onsite supplemental water wells or utilizing reuse from
WWTP #1.
1.2 - Scope of Services
The scope of services included:
Planning and preliminary design services for two irrigation options at SMCC
include:
New Onsite Wells at the SMCC to Supplement Current Source from Stormwater
Ponds
• Historical data evaluation included the review of documents provided by
SMCC that includes existing maps of golf course, storm water ponds and
irrigation system; proposed golf course improvements such as golf course
modifications, development plans or concepts for new irrigation (costs,
ideas and conceptual plan for supply wells, ponds and golf course
irrigation system modifications). In addition, contact was made with St
Johns River Water Management District (SJRWMD) staff to discuss the
feasibility of permitting new wells (since the District has been involved in
the preliminary design concepts with SMCC personnel).
• Since SMCC has in the last few years looked closely at development that
included using onsite wells for new irrigation sources, it was anticipated
that the historical data available was significant enough that no preliminary
design would be required.
• Present a summary of findings and provide updated costs and description
of work effort required to install and implement onsite wells for golf course
irrigation. The results and findings are presented in this document

SUPPLY FOR SELVA MARINA COUNTRY CLUB).
New Reuse Water Supply from City of Atlantic Beach
• Historical data evaluation includes the review of Technical Memorandum
#4 — Task 1 — Preliminary Evaluation for Reuse Treatment Components for
Selva Marina Country Club (2008).
• Review the previous reuse upgrades proposed in TM#4 and update costs
and consider options to reduce the project costs
• Develop method to transport reuse to the golf course to existing storm
water pond or new pond and interconnect to existing golf course irrigation
system.
• Prepare a summary of findings and provide updated costs and description
of work effort to install and implement reuse facility upgrade at or near
WWTP #1 for irrigation purposes. The results and findings are presented in
this document (EVALUATION OF OPTIONS FOR LONGTERM

SECTION 2.0 - IRRIGATION WATER SUPPLY OPTIONS
2.1 - Irrigation Water Supply Options Summary
The two options evaluated for irrigation water supply at SMCC were:
• New Onsite Wells at the SMCC to Supplement Current Irrigation Water
Source from Stormwater Ponds /Sherman Creek
• New Reuse Supply from City of Atlantic Beach to Replace Current SMCC
Irrigation Water Supply
2.2 - New Onsite Wells (Supplemental Supply)
2.2.1. - Summary:
JCEA and City Staff met with SMCC Officials during the study period and
discussed the previous engineering and /or developer efforts to secure a
supplemental water supply for the golf course. SMCC was very helpful with
providing and discussing historical data and providing an onsite tour.
During discussions with SMCC Officials, it was determined that the irrigation
demand for the Golf Course is approximately 200,000 gallons /day with peak
demands around 600,000 gallons /day. Therefore - if the stormwater
ponds /Sherman Creek irrigation water supply was not available during dry
periods, the supplemental wells would need to provide 200,000 gallons /day and
have adequate storage to meet the peak demands.
Based on the SMCC visits, meeting and review of historical data, the most recent
current plan was to install ten (10) new surficial wells to provide supplemental
irrigation; install new onsite storage pond (with liner); relocate or replace the
existing golf course pumping station and install new piping to interconnect the
new wells, new storage pond and new or relocated pumping station. In addition
SMCC planning includes an updated golf course irrigation distribution system but
this work is not relative to this water supply study (only considers water supply).
While the scope of work did not include any Preliminary Engineering Design to
supplement work accomplished at SMCC by others, it was our opinion that 10
wells from the surficial aquifer would most likely not be an adequate and reliable
supplemental water supply. The key reasons for this were:
• Based on historical wells in the area (data obtained from St. Johns River
Water Management District historical well logs) - surficial aquifer wells will
not deliver a reliable or adequate supplemental water supply. Alternate
considerations would be utilization of a deeper wells from the Intermediate
Aquifer and installation of more wells
• The current St. Johns River Water Management District Consumptive Use
Permit (CUP) #619 for SMCC allows for wells as a supplemental irrigation
source. The permit allows for a total of 10 surficial aquifer wells but these

wells are only permitted to be used on an emergency backup and for a
grow -in period of developing new grass. The use of these wells for
emergency irrigation are when the surface water supply is insufficient to
provide irrigation to the golf course. Therefore, if the well option is
implemented and the quantity of wells are increased or a deeper well is
planned (Intermediate aquifer), a new or modified CUP permit would have
to be obtained (requires new CUP application and renewal process).
In order to develop an alternative solution to the proposed 10 well - surficial
aquifer option proposed at SMCC, JCEA performed preliminary well designs
within the scope and budget of this project (no additional fee). The preliminary
design effort included discussion with two local well drillers.
Based on the preliminary design efforts for the onsite wells; JCEA developed two
well options:
Option C -1 -25 Wells - New Design - Based on review of the 10 wells option, a
new option was developed to install more wells drilled into the Intermediate
Aquifer (to obtain a higher volume of irrigation water). While the number of wells
could not be verified until the results of onsite test wells are installed and tested,
a lower more conservative GPM was assigned to each well (based on historical
wells and discussion with well drillers). The result is that as many as 25 wells
would be required to develop a reliable supplemental irrigation water supply.
Work under this option would include: A new application for a new or modified
CUP; develop test wells; depending on the results - install up to twenty -five (25)
new Intermediate Aquifer wells and a lined storage pond. The costs (capital,
operating, maintenance, labor and life cycle) associated with this option
(increased quantity of deeper wells) were developed. A construction estimate
only was prepared for the new lined storage pond. The storage pond would be
required in all well or reuse scenarios /options. For the basis of this report, the
new storage pond would be constructed as a part of any re- development/site
work of the SMCC property since the location of the pond is not known at the
present time. While this option was developed to increase the quantity of
irrigation water available (via an increase in the number of wells), the option is
not ideal due to the permitting (SJWRMD) efforts required and the difficulty of
locating as many as 25 wells and associated piping /electrical throughout the
SMCC property.
Option C -2 -10 Wells - Modified Design - To increase the like hood that 10 wells
would provide an adequate supplemental water supply- a new conceptual plan
was developed. Prepare a new application for a CUP and develop test wells for
both Surficial and Intermediate Aquifer to determine available water supply.
Depending on the expected results - install ten (10) new Intermediate Aquifer
wells and a lined storage pond. Unfortunately, based on historical well data in the
area - the 10 wells installed into the Intermediate Aquifer are still not expected to
provide an adequate and reliable supplemental water supply. The costs (capital,
operating and life cycle) associated with this option were developed but this
option was removed from consideration due to the reliability factor (not meet

irrigation guantity demand).
2.2.2. - Cost Evaluation:
The costs (capital, operating, maintenance, labor and life cycle) associated with
Option C -1 (C -2 removed from consideration) are detailed below:
• Construction - $399,960
• Total 20 Year Life Cycle Operation &Maintenance (O &M) Cost Estimate
(includes construction, O &M and replacement costs) - $1,608,173
2.3 - New Reuse Water Supply from City of Atlantic Beach to Replace
Current SMCC Irrigation Water Supply
2.3.1. - Summary:
City of Atlantic Beach operates Wastewater Treatment Facility #1 (WWTP #1) just
south of the SMCC that is capable without expansion of treating 3.5 MGD
wastewater. Currently WWTP #1 is now equipped with effluent polishing filters
that were installed during the recent Biological Nutrient Reduction Program. The
new filters will now allow the city to produce reuse without the cost of adding new
filters. In order to provide Public Access Reuse or Irrigation Quality Water, the
improvements that the City would need to focus on to produce reuse water -
would be upgrades to provide high level disinfection.
As previously discussed, during discussions with SMCC Officials, it was
determined that the irrigation demand for the Golf Course is approximately
200,000 gallons /day. For purposes of the reuse option in this report
(development of options and costs) - all options are based on 250,000
gallons /day.
With the amount of infrastructure in place and owned by the City in the vicinity of
SMCC, the opportunity existed for multiple reuse upgrade options. This included
construction at the current WWTP, construction at SMCC site (dedicated
property to COAB) and considerations for use of existing piping to transport flow.
Based on the preliminary design efforts for the reuse treatment facilities; JCEA
developed the following multiple options:
Option A - New Reuse Facility at WWTP#1 Site
• A -1 New Ultraviolet Light (UV) Facility at WWTP #1 Site
• A -2 New Dedicated Chlorine Contact Chamber (CCC) Facility at WWTP #1
Site
A -3 Use of 1/2 of Existing CCC at WWTP #1 Site
• A -4 Use Existing Aquastore Tank from Buccaneer Site at WWTP #1 Site
Option A is shown in the following exhibit - General Layout for "A" Options -
Reuse Treatment Located at WWTP #1.

design details of the 10 options (A, B & D) for producing reuse water for irrigation
purposes at the SMCC golf course.
2.3.2. - Cost Evaluation:
The costs (capital, operating, maintenance, labor and life cycle) associated with
each reuse facility option (A, B & D) is listed in Attachment B.
Operation and Maintenance (O &M) costs vary for each reuse option - therefore
each alternative was evaluated separately to determine the associated costs of
items such as: labor, electrical , major maintenance expenses (which occur at
various future dates depending on the life of the equipment), chlorine supplies
and major consumable items.
2.4 - Findings and Recommendations
2.4.1. - Overview:
As discussed within, the first task in the development of an irrigation source was
to develop a number of viable alternatives. In order to compare multiple irrigation
concepts and to determine the most cost effective selection - a total life cycle
cost concept (LCC) was utilized. The LCC is a "whole life cost" analysis that
determines the real cost of ownership over the life of an asset. Costs were
developed for each alternative to include capital, operation, maintenance and
labor costs. A life cycle comparison was then completed on all options and a
comparison was made to select the most economical alternative /option.
A table at the end of this report presents the results of Life Cycle Cost
Comparison (LCC):
The best and recommended alternative is the construction of a new reuse
treatment facility at WWTP#1 referred to as Option D -1 - New UV Facility location
at WWTP #1.
2.4.2. - Reuse Program Recommendations:
If the City implements the recommended reuse option (Option D -1 New UV
Facility at WWTP #1 Site - Use Existing 6" Pipe, there will be several coordination
issues to address:
1. City would be constructing a new reuse facility that would produce an
average of 200,000 gallons per day (gpd) of Public Access reuse water.
For the golf course to meet the irrigation requirements during dry and hot
periods, a lined storage pond (approximately 3 million gallons) would need
to be constructed somewhere on the golf course by SMCC. For purposes
of this report, the pond location was assumed to be in the southwest
corner of the SMC property. If the pond is located in another area of
SMCC, additional onsite pipe will be required to extend the reuse into the
site of the new storage pond.
2. Implementation of Option D -1 will require the conversion of a portion of the
J. COLLINS ENGINEERING ASSOCIATES, LLC Page 12
AGENDA ITEM # 8A
JANUARY 28, 2013
existing 6" diameter force main from Fleet Landing to a reuse main. The
new 12 "718" force main (part of the phase out of Buccaneer WWTP) is
located in an easement in Fleet Landing and has adequate capacity to
allow the Fleet Landing Lift Station to be interconnected and the 6" force
main can then be abandoned. The interconnection to the new 12 "/18 "force
main was part of the design, but coordination will be required with Fleet
Landing to investigate the effect of the interconnection. The existing Lift
Station may require pump modifications due to an increased pumping
condition (higher head conditions).
3. The recommendation is to upsize the reuse treatment facility to 250,000
gpd for a safety factor and to allow the City the potential to provide
residential reuse for any new homes constructed during the
redevelopment of the SMCC property. While residential reuse was not part
of the scope of this study, if in the future residential reuse is planned in the
new home development of SMCC property, at a minimum a separate new
reuse pipe would be required to deliver a pressurized reuse. The existing
6" pipe is only adequate to be used for filling the new storage pond with
reuse water. In order to deliver pressurized reuse water to the new
residential homes, a new separate reuse pipe from WWTP #1 would be
required as well as the addition of higher pressure pumps, also located at
WWTP#1.
4. A new reuse facility at WWTP#1 can be implemented to provide a reliable
irrigation supply for SMCC, but the recommended option (UV Reuse
Treatment Facility)is only sized to provide reuse for the immediate use by
the SMCC golf course and includes a reasonable amount of new homes.
In the event the City decides to provide reuse to other areas, the proposed
UV treatment capacity would have to be upsized or replaced and new
reuse pipes as well as reuse pumps would be required in order to expand
this new reuse facility.
