NAPLES BEACH STORMWATER OUTFALLS - SCOPE OF SERVICES (AMENDMENT 4)PURSUANT TO THE AGREEMENT BETWEEN THE CITY OF NAPLES AND ERICKSON CONSULTING

ENGINEERS, INC

PROJECT DESCRIPTION

This Scope Amendment (Amendment 4) is to outline the amended scope of services to complete

the tasks as directed by City Council at a September 17, 2020 Special Meeting, following the

September 14, 2020 City Council Workshop at which Project Structure, Water Quality Goals, and

Key Components were presented and reviewed by City Council.

Adjustments to the Scope of Services included herein are specific design, permitting, and final

engineering tasks necessary to achieve the goals set forth by City Council, including:

. Modify the design and permits for the South System (Outfall Basins 5-10, further

described below) and design and permitting of the North System (Outfall Basins 2-4,

further described below) in accordance with Project Structure Alternative A (described

below).

. Include a public outreach component that assists staff with necessary graphics and

technical support.

. Continue to engage volunteer members of the Environmental Review Committee.

PROJECT BACKGROUND

There have been long-standing concerns from the State's regulatory agencies, City officials andstaff, environmental groups, property owners, residents and visitors that the beach outfalls

adversely impact beach erosion, lateral beach access, sea turtle nesting habitat, water quality

and beach aesthetics. In addition, the City has experienced significant flooding of Gulf ShoreDrive during high frequency rainfall events.

In 2012, the City adopted Resolution No 12-13028 and amended their stormwater master plan

to require^the removal of the City's stormwater beach outfalls. In September 2015 to June 2016,

Erickson Consulting Engineers, Inc. (ECE) conducted a technical analysis and presented the Design

Development Phase 1 to the City Council assessing the feasibility of and providing a design (30%)

for consolidation of the nine publically owned outfalls to a stormwater pump station(s) in alocation that would receive all or a portion of the stormwater currently discharging along Naples

Beach (Drainage Basin II); and discharge the collected and treated stormwater through anoffshore gulf discharge pipeline(s). This work was detailed in a report by ECE entitled "Naples

Page | 1


Beach Restoration and Water Quality Improvement Project: 30% Design Technical Report" datedMay 2016.

The City Council directed City Staff to proceed with Project Structure Alternative A, as more fully

described in the Agenda Memorandum for Item 6-A presented at the September 14, 2020 City

Council Workshop and at the September 17, 2020 City Council Meeting.

The Project Structure Report included the identification and ranking of three (3) alternatives thatmet the prescribed project goals and objectives which include:

1. Reduce flooding and provide measurable water quality improvements;

2. Eliminate erosion rates from outfall induced scour and improve lateral beach access byremoving pipelines;

3. Reduce adverse impacts to the beach and nearshore natural resources (sea turtles and

hardbottom);

4. Meets or exceeds the existing level of Service (LOS) to convey flows and improve the

stormwater system's resilience for:

a. 5-yr/l-hr rain event (City of Naples Comprehensive Plan);

b. 5Yr/24-hr rain event, and the

c. 25-yr/3-day rain event (SFWMD);

5. Convey treated stormwater to a pump station(s) and offshore; and

6. Community education and outreach (project goals & objectives).

City Council directed staff to proceed with Project Structure Alternative A, which is comprised of

a north system and a south system as follows:

North Drainage and Treatment System (North System) - consolidates the existingstormwater flows associated with Outfalls 2, 3 and 4 (25-Yr 3 day), redirects flows from

7th Street North and South Golf Drive (currently draining into the Alligator/South/NorthLake system), and conveys the flows to a pump station located in the vicinity of the Naples

Beach Hotel and Golf Club with treatment and discharge lines deep drilled and a diffuser

system placed offshore in the Gulf. All pipeline consolidation is along Gulf Shore Blvd.

and the portion of South Golf Drive between Gulf Shore Blvd. and approximately 7th

Street. The north system treats 100% of the 25-yr peak flow through the pump station.

South Drainage and Treatment System (South System) - consolidates the existingstormwater flows associated with existing Outfalls 5, 7, 8, 9 and 10 and the portion of

Outfall 6 south of 7th Avenue North (25-Yr 3 day) and conveys these flows to a pumptation located at 3rd Avenue North with treatmentand discharge using directional drilled

Page | 2


deep pipelines through an offshore diffuser system. The south system treats 57% of the

25-yr 24 hour peak flow through the pump station. An overflow line will be located at

Outfall 6 to convey stormwater during extreme storm events when peak dischargevolumes exceed the maximum rates for the pump stations, by diverting the flows from

Alligator Lake. The overflow line will be located below the visible beach and open only

during extreme storm events, estimated to occur once in 10-15 years and when AlligatorLake Water Levels exceed the designated storage limits at 3. 25 feet. The potential exists

for pipeline consolidation along the back-beach or Gulf Shore Blvd.

The scope of work described herein continues the development of the Project StructureAlternative A North and South Systems, hereinafter referred to as the "Project, " through the

detailed design, permitting and bidding phase based on the following tasks.

Task 1. Project Administration and Contract Management

Task 2. City Council Meetings, Environmental Advisory Coordination and Grant

5) The Engineer will rely on Collier County's Spring 2020, or more recent as it becomes

available, beach profile and bathymetric data and sub-bottom sediment depths for

the design of the directionally drilled line. This Scope does not include bathymetric

mapping of the offshore discharge site.6) Mapping of the hardbottom in the Gulf of Mexico near the outfall shall be conducted

to verify the locations of the HDD diffusers. A preliminary Historical Data Analysis will

be performed to determine historic hardbottom coverage and persistence in the area.

A side-scan sonar imagery survey will be conducted to delineate areas of different

surface type to map potential hardbottom within the survey area. A field survey will

be performed along a 1,200 to 1,700 foot radii from the City's existing drainage

easement near Oleander Drive and GSB, focusing on the seaward edge of the

hardbottom, to assess of major benthic functional groups (e.g. seagrass, stony coral,

gorgonians, macroalgae, sponges, and tunicates), which is intended to satisfy

requirement for environmental permits. If present, coral colonies will be identified tospecies level and assessed for maximum size (to nearest cm) and overall health.

Representative photographs/video will be taken using an underwater camera.

Electronic survey files signed and sealed by registered land surveyor will be provided to the City.

The scope does not provide for a subsurface utility locate to determine utility conflicts. These

services, if needed, will be provided as an additional service.

Task 3B: Geotechnica I Invest! ation Dee Core Bonn

One (1) standard penetration test (SPT) boring will be performed to determine the nature and

condition of the subsurface soils. The boring will reach 80-100 ft below the natural ground

surface or at least 20 feet into limestone rock exhibiting a minimum blow count of 50, whichever

is less. Any limestone encountered will be characterized by recording Time-Pressure Cutting

Profiles that record the time it requires to drill through 12" of limestone with a specific down

pressure on the drill bit. This will give a profile of relative rock consistency/hardness. For design

of the pump station, samples will be taken to a depth of 50 ft below the surface at 5 foot intervals

and tested to determine (a) soil stratification, (b) a generalization of subsurface soil conditions

encountered in the borings, (c) analysis of existing soil conditions with respect to the proposed

construction of the pump station and (d) standards soil gradation, as necessary, should materials

other than sand be encountered. Sediment samples analyzed and described from the log shall

be of sufficient spacing and frequency to adequately describe the sediment layers within thecores. Individual sample analysis and total sample composite analysis shall be provided including

percent silt, organics, rock and debris, as well as, any other significant compositions. The cores

will be cataloged using standard drilling log forms, granularmetric reports, and rain size

distribution plots with the testing and analysis performed to characterize the sediments usingPage | 7


-^-.L'WB. -^

standard statistical methods (mean, standard deviation, etc. ).

A geotechnical report summarizing the findings of the boring, signed and sealed by a professional

geotechnical engineer, will be provided to the City.

Task 3C: Basema s

The data acquired and compiled will be used to update the Project's base drawings and maps

and utilized throughout the design, permitting and construction phases to create design andworking drawings. The compiled base maps in AutoCAD format (2015/16) will be distributed to

the City and the Project sub-Engineer(s), as appropriate.

In addition to the basemaps, the work products and findings forthe Supplemental Data Collection

and Mapping work will be presented in monthly progress meeting(s) and through a brief andconcise technical memorandum.

Task 4: Storm Water Modeling

Storm water modeling required for the project includes four main modeling tasks: (1) Revise the

approved and permitted InfoSWMM model for Basins 5-10 to remove the impervious areasassociated with the sidewalk and re-compute flows, (2) Model the reduced South Pump Station

with flows along 3rd Street re-routed to Alligator Lake (or South Lake), (3) Model the North PumpStation and revised Sub-Basins 2-4 and 6, and (4) Prepare the Plume/Sediment Mixing Zone

Modeling for the North Diff user System.

The SYr-lHr, 5Yr-24Hr and 25Yr-3Day rainfall hydrographs will provide the hydrology forcing. The

1 %" rain event will also be modeled to assess pump station cycling for higher frequency events.Compilation and analysis of measured data with comparison to prior stormwater studies will

drive the model development. The model will then be developed and adjusted to represent the

observed stormwater staging and flows in Sub-Basins 5-10 (South System) and Sub-Basins 2-4

(North System) of the City of Naples' Basin 11. Following the model verification, tl-Te SYr-lHFand

25Yr-lHr (City Requirement) and 25Yr-3Day (District Requirement) events will be simulated for

the Project design development to revise the trunklines and pump stations for the system's"design" operating conditions. The extent of the South System model domain will cover Basin II

from 2nd Avenue South (at the south end of the Project Area), up to 7th Avenue North (at thenorth end of the Project Area); the extent of the North System model domain will cover Basin II

from 7th Avenue North (at the south end) to the northern limits of Sub-basin 2 within the City ofNaples' Basin II.

Page | 8


The stormwater model studies will be summarized in an updated and revised report including adescription of the revisions to the model setup, sub-basins, pipeline system, collected data,

comparison with prior studies, and results. The report will be provided to the City and the State

(SFWMD /FDEP) as part of the regulatory permitting revisions.

Task 4A: South Pum Station - Revise Permitted Model to Remove Bike Lanes

The model for the South System (as permitted) will be revised to remove the impervious area

associated with the bike lanes. The impervious area calculations for Basins 5-10 will be updated,and run-off simulations will be performed to calibrate the updated model to the permittedconditions.

Task 48; South Pum Station - Reroute 3rd Street Draina e

The model developed and calibrated in Task 4A will be further modified to re-route flows from

3rd Street to either Alligator Lake or South Lake.

Task4B. l: Model Setu - Revise Basin Boundaries Im ervious Areas 3rd St. Surve and

or sub-catchments

The Model will include adjustments to total and impervious areas in Basins 6, 7 and 8 toshift drainage (from Basins 7 and 8 within the 3rd Street Corridor) to Basin 6. Sub-

catchments will be updated according to the survey data collected underTask 3A. 1 above.

The Engineer will design a new trunkline within the 3rd Street corridor to collect and routeflows to Alligator Lake, and review of the trunk line sizing on Gulf Shore Blvd. between 2ndAvenue South to 3rd Avenue North to allow increased distance between the trunk line and

adjacent properties.

Task4B.2: Model Veri ication - Corn are Simulated elevations lows with Previous Model

In ormation

Model verification will include adjustment of friction coefficients, impervious areas, andpre-storm upstream storage until agreement is obtained between observed and re-simulated data to meet the District (or FDEP) acceptance.

Task 4B. 3: Run-o Simulations 5 rlhr 5 r 24hr 25 r 3 da - 3rd St. to All! ator Lake

and 3rd St. to South Lake

The SYr-lHr and 25Yr-lHr (City Requirement) and 25Yr-3Day (the District Requirement)

events will be simulated for the Project design development to evaluate the trunkline,pump station and overflow line for the system's "design" operatin conditions.

Page | 9


Tasks 4B.4: Pi eline Consolidation 0 tions 2nd Ave. South vs. Central Avenue

The resulting model will be applied to assess the design of the Project and varying systemcomponents (conduit geometry, capacities, and alternatives) to evaluate the Gulf Shore

Blvd. trunk line, the 3rd Street trunk line, and re-evaluate the pump station and overflowline for the system's "design" operating conditions.

The Engineer shall design the trunkline (main conveyance line which runs along Gulf Shore

Blvd and conveys flows from Outfalls 5, 6, 7, 8, 9, and 10 to the South pump station) and

feeder lines (connection of stormwater system inlet drainage to the main trunk line for

(Outfalls 5-10). In addition, the Engineer shall design a trunk line (main conveyance line

which runs along 3rd Street) to route flows from the 3rd Street Corridor to Alligator Lakeor South Lake.

The trunk line and feeder lines will be sited to minimize conflicts with existing utilities(power, re-use, sewer, potable water, etc. ) to the greatest extent practical;

Trunkline locations, alignments, and elevations will meet the 25 year, 3 day LOS. The LOS

will meet or exceed the City's minimum level of service (5-yr/l-hr and 25-yr/l-hr) and by

the requirements of the South Florida Water Management District (25-yr/3-day) for state-

level permitting.

The size of the required stormwater trunk line infrastructure will be determined based on

output and results of the stormwater system model simulations (Task 3C). Collection

points will be utilized where feasible at all existing inlet structures to minimize road and

new construction. The consolidation of feeder lines will be limited to those collection

points already identified within the North Gulf Shore Boulevard ROW and the ROWs of

the beach access streets to the west of North Gulf Shore Boulevard between North Lake

Drive (Outfall #5) and 3rd Avenue South (Outfall #10).

Existing inlet collection points within the 3rd Street ROW will be utilized where feasible at

all existing inlet structures to minimize road and new construction. The consolidation of

feeder lines will be limited to those collection points identified within the 3rd Street ROW

and the ROWs of intersecting streets between 1st Avenue North and 3rd Avenue North to

Alligator Lake or South Lake.

The consolidation, re-design and/or re-sizing of feeder lines and stormwater collection

points east of the 3rd Street ROW are not anticipated; however, existin connection ofthese lines to the 3rd Street stormwater system will be maintained. The re-direction of

Page | 10


existing trunk and/or feeder line stormwater conveyances to locations other than the

proposed Gulf discharge is outside the SOW presented herein.

Task 4C: North Pum Station

Task 4C. 1: Model Setu and Preliminar Simulations - Ex. Conditions & Re-route SGD to

GSB to Validate Ex. Conditions.

Available topographic and infrastructure (stormwater conduit and structures) survey

data, as well as data obtained from prior field data collection efforts, will provide therequired data/information to build out and confirm the model. These data will be

analyzed to provide a characterization of the hydrologic and hydraulic processes that the

model will simulate. These data will also be analyzed to provide the necessary model

inputs and comparison data sets for sub-basin set-up, and the baseline conditions Level

of Service (LOS) to evaluate required improvements to meet the City's required LOS (5-yr/l-hrand25-yr/l-hr).

The model setup will require several data sets. Baseline topographic and infrastructure

(stormwater conduit and structures) survey information will be utilized as the digital, geo-

referenced basemap of the model domain. This information will be used to verify and/or

modify the sub-basin boundaries delineated by AECOM (November 2011). Topography,

inlet and conduit geometry, and rainfall hydrographs will provide the inputs to the model.

The model verification will require data observed and measured water levels, flows and

rainfall for comparison to simulated staging during the model verification process.

Task 4C. 2: Model Basin Modi ications STL Storm Sewer Pum HDD and Roadwa

Revisions.

The model will be refined for Sub-Basins 2-4. The model space defines the model nodes,

links and storage areas, stormwater conduits and overland flow.

Model will include adjustment of friction coefficients, impervious areas, and pre-stormupstream storage until agreement is obtained between observed and simulated data.Comparisons will include qualitative (i.e., water surface elevations and flows) and

quantitative analysis and observational agreement.

Task4C.3: Runno Simulations 5 rlhr 5 r 24hr 25 r 3 da GSB Flows to NPS

The SYr-lHr (City Requirement), 5Yr-24Hr and 25Yr-3Day (the District Requirement)

Tasks 4C.4: Pi eline Consolidation 0 tions and Pum Station 0 tions

The resulting model will be applied to assess the design of the Project and varying systemcomponents (pipe geometry, capacities, and alternatives). These initial simulations will

provide data to refine the design of the system hydraulics and for the trunkline, pump

station and offshore outflow designs for varying directionally drilled line geometries andoffshore operating conditions.

The model will be applied to simulate the Project performance and resulting level of

service; including simulating the Project effects on upstream staging.

The Engineer shall prepare the detailed design for the pipeline consolidation including the

consolidated trunk line and feeder lines and associated utility, easement and structural

conflicts. The Engineer will design standard concrete replacement sections for drivewaysimpacted as a result of the consolidated trunkline and feeder line placement.

At the project initiation meeting, the City shall provide direction as to the routing of the

consolidated trunkline along the North or South ROW of South Golf Drive. Design of the

trunk line and feeder lines along GSB will require coordination with the developers of the

NBC and their design professionals.

The Engineer shall design the trunkline (main conveyance line which runs along N Gulf

Shore Blvd and conveys flows from Outfalls 2, 3, and 4 to the North pump station) andfeeder lines (connection of stormwater system collection points to the main trunk line for

(Outfalls 2-4). In addition, a new trunkline carrying flows collected along S. Golf Drive and

presently discharging into North Lake will be designed to redirect stormwater away from

the three lake system and GSB Sub-basin 3 to the North Pump Station.

The trunk line and feeder lines will be sited to minimize conflicts with existing utilities(power, re-use, sewer, potable water, etc. ) to the greatest extent practical.

The line locations, alignments, elevations and level of service (LOS) will be specifically

identified in the design. The LOS will meet or exceed the minimum level of service as

specified by the City of Naples Comprehensive Plan (5-yr/l-hr) and by the South Florida

Water Management District (25-yr/3-day) for state-level permitting.

The size of the required stormwater trunk line infrastructure will be determined based on

output and results of the stormwater system model simulations (Task 4C. 3). Collections

points will be utilized where feasible at all existin inlet structures to minimize road andnew construction. The consolidation of feeder tines will be limited to those collection

points within the North Gulf Shore Boulevard ROW and the ROWs of the beach access

streets to the west of North Gulf Shore Boulevard between North Lake Drive (Outfall #4)

and 3rd Avenue South (Outfall #10). The consolidation, re-design and/or re-sizing offeeder lines and stormwater collection points east of the North Gulf Shore Boulevard

ROW are not anticipated; however, existing connection of these lines to the North Gulf

Shore Boulevard stormwater system will be maintained. The re-direct of existing trunkand/or feeder line stormwater conveyances to locations other than the proposed Gulf

discharge is outside the SOW presented herein.

Task 40: Plume Sediment Mixin Zone Modelin

The mixing zone for the freshwater discharge to the gulf waters is a function of the flow rates,

water depths and diffuser system design. A mixing zone analysis will be developed based on the

discharge rate from the North Pump Station, in conjunction with FDEP and USAGE requirements,

to address salinities resulting from the discharge of stormwater to refine and maximize the

dilution rate(s) at the discharge point. The EPA's Visual Plumes model system (or other method

approved by FDEP) will be used to simulate the expected mixing and dispersion. Suspended

sediment modeling is not expected to be required. If this should exceed the state allowablemixing zone of approximately 150m, a separate application for a mixing zone variance will be

required in the permitting phase (mixing zone variance request).
