Scope of Work for:

Rookery Bay National Estuarine Research Reserve

Henderson Creek Flatwoods & Low-water Crossing

Hydrologic Enhancement Project: Phase 2

Background: The FDEP reached out to Mott MacDonald (MM) to provide the following services under the BS135 statewide contract. The project tasks were broken out into two phases. Phase 1 was complete in February of 2023. This scope is for Phase 2.

Project Area Significance: Forested and non-forested coastal freshwater wetlands were bisected by a roadway and powerline right-of-way before the area was designated a reserve. The roadway and right-of-way are necessary for infrastructure and resource management access, both from Florida Power and Light and the NERR staff. The roadway alters forested wetland hydrology by collecting and channeling water away, causing a drying of hydric flatwoods and invasion of exotic plants. The shell-capped right-of-way has six low water crossings in disrepair that facilitate flow across the non-forested marsh system.

Current hydrological and habitat conditions are altered and facilitate invasion by exotic plant species such as melaleuca, Brazilian pepper, ear-leaf acacia, and Australian pine. Restoration of historical flow patterns will benefit 1,300 acres of wetland habitat. Hydrological modeling as part of the engineering and design of Phase I will determine if additional low water crossings are warranted. Phase I will also design and permit the low water crossings and relocation of the dirt roadway to a fence-line. Restoration of the current roadway to hydric flatwoods and other construction will occur in Phase II.

Project Description: The project is located at the Rookery Bay National Estuarine Research Reserve (RBNERR) in Collier County, Florida approximately 10 miles south of the City of Naples. The entrance to the RBNERR is located off Tower Road approximately 0.2-miles west of Collier Boulevard (SR 951). The RBNERR encompasses an area of approximately 110,000 acres comprised of a mixture of land and water that is part of the Everglades ecosystem. The Rookery Bay National Estuarine Research Reserve is managed by the Florida Department of Environmental Protection's (FDEP) Coastal Office in cooperation with the National Oceanic and Atmospheric Administration (NOAA).

Approximately 1,300 acres of state-managed wetlands within Rookery Bay National Estuarine Research Reserve (RBNERR) lying west of Tower Road have experienced hydrological alteration from two roadways identified as Trash Road located at the east end of the RBNERR and Powerline Road located within an existing Florida Power and Light (FPL) easement.

Trash Road contains deep ruts and low spots where sheet flow is intercepted and concentrated in channels. Therefore, the water is redirected westward to the coastal wetlands and away from the hydric pine flatwoods to the south. This has caused a subsequent drying of the wetlands down gradient in the hydric pine flatwoods and allowed exotic invasive plant species to invade.

Bottlenecked overland flow in wetlands from six undersized low water crossings (LWCs) along Powerline Road, in addition to upstream urbanization, has caused degradation of habitats to the northeast of Powerline Road. Upstream inflows have changed due to local housing development storm water management and changes in runoff patterns. Wetland ponding and sheet flow which formerly began near the onset of the rainy season in July are now delayed up to a month because of mandated retention and treatment by the developments. The effect has been to shorten the hydroperiod of the project area and allow for tidal habitat encroachment. Restoration actions will enhance wildlife habitat and water quality by extending the period of flooding in hydric flatwoods, attenuating nutrients, excluding exotic plant species intolerant of flooding, and facilitate connectivity across the coastal wetland continuum. The six existing LWCs along Powerline Road are degraded and crumbling due to heavy use and age and restrict water flow to the southwest.

RBNERR is providing this narrative to facilitate a request for proposal to include design services and permitting services to remove and relocate Trash Road to restore historical sheet flow patterns and upgrade the existing six low water crossings along Powerline Road to improve the passage of water to restore wetland hydroperiods. Upgrade of LWC’s may include replacement with a combination of large box-culverts and/or small bridge-spans. The project includes the following components as described below and depicted on Figure 1 – Project Area Map:

Relocating Trash Road to extend approximately 3,360-feet along the northern fence line and southward along an existing wetland.

Determining the length and/or number of low water crossings along

Powerline Road to effectively restore wetland hydroperiods by updating and modifying the existing integrated surface water model originally prepared for the RBNERR.

Designing new low water crossings based on the results and conclusions determined from the hydrologic model. At a minimum the project will include removing and replacing the six existing low water crossings with upgraded LWC infra-structure and/or with box culverts or small bridge-spans. All work must meet ratings to accommodate Florida Power and Light (FPL) heavy Trucks and other equipment. However, the lengths of the six existing low water crossings could be increased or additional low water crossings could be added.

Installation of bridge at northernmost extent of existing pictured section of FPL power-line access road is needed to provide land management (including prescribed fire and response to instances of wildfire) access northward across a small creek to continuation of the FPL power-line access road and easement.

The new low water crossing will be a long-lasting durable material comprised of interlocking blocks to provide a more durable driving surface that must meet the needs of access for FPL power-line maintenance trucks.

The 6-existing low-water crossings, existing Trash Road, and the proposed area to relocate Trash Road are located within and adjacent to wetlands and surface waters. Therefore, the scope of service includes quantifying the area of wetlands and surface waters impacted by the proposed improvements and the volume of material placed into the wetlands and surface waters to accommodate the construction of the proposed improvements. The scope of services includes discussions with the SFWMD, USACE, and Collier County to determine if the impacts require mitigation or if the project is self-mitigating due to the restoration of wetland habitats.

PROJECT APPROACH:

The tasks to be completed in by the ENGINEER for this scope of work are identified below along with a discussion of the ENGINEER’s approach to completing each task.

Task 1: Roadway Design Plans – The ENGINEER will develop a design and prepare construction plans to fill and re-grade the existing alignment of Trash Road, fill and grade the relocated alignment of Trash Road and reconstruct multiple low-water crossings along Power Line Road. The construction plans will show the existing alignment of Trash Road, the new alignment of Trash Road and the low-water crossings in plan, profile and cross-section views. The plans will also contain, general notes, temporary erosion and sedimentation controls, and details. The construction plans consisting of the following plan sheets will be submitted to the FDEP for review at final completion:

Coversheet (1 sheet) Signature Sheet (1 sheet) Overall Site Plan (1 Sheet) Typical Section and Details Sheets (3 sheets) General Notes (1 sheet) Plan Profile Sheets Existing Trash Road (12 sheets) Plan Profile Sheets of Proposed Trash Road (10 Sheets) Plan Profile Sheets of Low Water Crossings (9 Sheets) Cross-Section Sheets (6 Sheets) Sediment and Erosion Control Plan (4 sheets) Sediment and Erosion Control Details (2 Sheets)

DELIVERABLE:

1.) Submit Final design plans to include:

Final plans will be electronically signed and sealed by an

Engineer registered in the State of Florida Electronic files of the final construction plans in PDF format and CAD format

Task 2: Bridge Design Plans – The ENGINEER will develop a design and prepare construction plans for (2) replacement bridges, (2) new bridges, (5) new bridge culverts, and (1) new culvert to span over low-water crossings. The (4) bridges will utilize pile bents to minimize required excavation in the wetland areas. Micro piles installed with low-headroom equipment will be used to meet required clearances from the FPL electrical transmission lines. A low-profile superstructure will be utilized to minimize required roadway height. A standard bridge plan will be utilized for all bridges with the number of spans varied to match the location to reduce both design and construction cost. The bridge culverts and culvert will use precast box sections bolted together with connecting closure pours without a topping slab to reduce construction cost. Both the bridges and culverts use precast concrete components which will minimize site-cast concrete and reduce the potential for wetland contamination. The structures will be designed according to the AASHTO LRFD Bridge Design Specifications to carry HL-93 loading. Open W-beam railing will be used instead of typical bridge railing to reduce cost and minimize flow blockage during flooding events. The structural plans consisting of the following approximate plan sheets will be submitted to the FDEP for review at final completion:

Keysheet (1 sheet) Index (1 sheet) Signature Sheet (1 sheet) Quantity Sheets (7 sheets) General Notes (1 sheet) Project Layout (1 sheet) Typical Bridge Section (1 sheet) Typical Bridge Culvert Section (1 sheet) Report of Core Borings (3 sheets) Construction Sequence (2 sheets) Micro Pile Details (1 sheet) Precast Concrete End Bent Plan & Elevation (1 sheet) End Bent Details (1 sheet) Precast Concrete Intermediate Bent Plan & Elevation (1 sheet) Intermediate Bent Details (1 sheet) Approach Footing Plan and Details (1 sheet)

Task 8: Additional Hydrologic/Hydraulic Modeling Services – This task primarily includes additional hydrologic and hydraulic modeling in support of several potential hydrologic and habitat restoration projects within the boundaries of the RBNERR in coastal Collier County as described below:

Task 8.1 Meetings and Management

The ENGINEER shall attend a kickoff meeting for the additional services and regular progress meetings with RBNERR staff remotely via Zoom, Microsoft Teams, or other virtual meeting platform. Following the kickoff meeting, the ENGINEER shall prepare a detailed project schedule that meets the needs of RBNERR staff.

The ENGINEER shall prepare and submit monthly progress reports and maintain regular email and telephone communications over the duration of the project, assumed not to exceed 24 months. This task includes participation in up to three

(3) additional meetings with SFWMD, Collier County, and/or other stakeholders as needed to coordinate modeling of alternatives, if requested by RBNERR staff. The ENGINEER will participate in one meeting (in-person or remotely) to present the results of the hydrologic modeling analyses at the conclusion of this study.

1.) Submit additional project schedule and monthly progress reports.

Task 8.2 Simulate Henderson Creek Flatwoods Project Alternatives

The ENGINEER will assist RBNERR staff in refining this project design through modeling of alternatives, including the removal and relocation of Trash Road to improve overland flow to adjacent lands, and to restore historical sheet flow patterns. Modeling of this project will include proposed upgrades to the existing low water crossings of the FP&L powerline road, and an assessment of resulting hydroperiods to determine whether additional crossings are warranted. The objective of the low water crossings are to extend the hydroperiods of the hydric flatwoods downgradient of the powerline road. Model results will be used to estimate the difference in hydroperiods that can be expected as a result of the proposed improvements; the ENGINEER will generate hydroperiod maps and difference maps based on the 2-D model output. These results will be supplemented with wetland hydrographs and stage duration curves generated at up to ten (10) points of interest.

DELIVERABLE:

1.) Report (PDF format) summarizing the alternative analysis and results of the selected alternatives.

Task 8.3 Collier Boulevard Conveyance Improvements

The construction of Collier Boulevard (SR 951) decades ago effectively bisected the coastal freshwater and estuarine wetlands within the boundaries of what is now RBNERR. Although there are a handful of existing culvert crossings under the road, it is thought that the current cross drains are inadequate to accommodate the pre-development sheet flow (Figure 2).

Hydrologic and hydraulic modeling as part of this task will seek to determine to what extent the flows under this road need to be expanded to restore historical flow patterns. The ENGINEER will evaluate the addition of new culvert crossings and potentially raised bridges, and the need for spreader swales. MIKE SHE modeling results will be used to generate pre- and post-project hydroperiods on both the east and west sides of the road. Hydroperiod difference maps (based on 2-D gridded model output) will be generated to convey the potential hydrologic improvements that can be achieved. These results will be supplemented with wetland hydrographs and stage duration curves generated at up to six (6) points of interest to be defined by RBNERR staff.

1.) Task Report describing the model results and recommendations.

Task 8.4 Marco Shores Lake Tidal Connection

The Marco Shores Lake lies on the north side of Mainsail drive and extends east along the road to the Marco Island Executive Airport (Figure 3). Water levels within the lake are controlled by a weir/spillway on the western side of the lake, which discharges into a tidal creek flowing under Collier Boulevard (SR 951). The purpose of this project is to create or restore a tidal connection to the Marco Shores Lake system to provide opportunities for commercially important fish species to gain seasonal access to this system.

The ENGINEER will evaluate lake levels with the spillway removed and compare with current conditions lake levels. Specifically, the assessment will focus on how the lake levels will respond to the tidal signals (diurnal and semi-diurnal) once the spillway is removed. If adequate survey data of the downstream tidal creek exists and can be provided as part of Task 15.2.3, the ENGINEER will evaluate critical water depths and flow velocities with respect to fish passage criteria. The results of the analysis will be summarized in a brief Task Report.

1.) Task Report describing the model results and recommendations.

Task 8.5 Road to Nowhere Conveyance Alternatives

The Road to Nowhere extends east from the Marco Island Executive Airport, over a distance of approximately one mile, and dead-ends in a forested wetland system. This project would restore a more natural, possibly tidal connection between the north and south sides of this road and provide a more connected hydrologic system overall. This would be accomplished by installing a series of culverts or low-water crossings (Figure 4).

The ENGINEER will evaluate and preliminarily assess whether the proposed hydrologic system can be achieved. Prior to simulating model scenarios, the ENGINEER will compare current conditions water levels with recorded data in the vicinity (if available), to be provided by RBNERR staff. Model parameters will be adjusted locally, if necessary, to provide an acceptable match between simulated and observed water levels at up to four (4) locations. Modeling will be conducted to provide a comparison between current conditions and with-project conditions.

Model results will be used to generate pre- and post-project hydroperiods on both the north and south sides of the roads. Hydroperiod difference maps (based on 2-D gridded model output) will be generated to convey the potential hydrologic improvements that can be achieved. These results will be supplemented with wetland hydrographs and stage duration curves generated at up to six (6) points of interest to be defined by RBNERR staff.

Task 8.6 Shell Island Road Alternatives

The construction of Shell Island Road likely disrupted historical sheet flow patterns within what is now RBNERR, west of Collier Boulevard (Figure 5).

Figure 5 – Eastern Shell Island Road Potential New Culvert Crossings

Hydrologic and hydraulic modeling as part of this task will seek to determine to what extent the flows under this road need to be expanded to restore historical flow patterns. Prior to simulating model scenarios, the ENGINEER will compare current conditions water levels with recorded data in the vicinity (if available), to be provided by RBNERR staff. Model parameters will be adjusted locally, if necessary, to provide an acceptable match between simulated and observed water levels at up to four (4) locations.

The ENGINEER will evaluate the addition of new culvert crossings. MIKE SHE modeling results will be used to generate pre- and post-project hydroperiods on both the southeast and northwest sides of the road. Hydroperiod difference maps (based on 2-D gridded model output) will be generated to convey the potential hydrologic improvements that can be achieved. These results will be supplemented with wetland hydrographs and stage duration curves generated at up to six (6) points of interest to be defined by RBNERR staff.
