1 INTRODUCTION

1.1 SCOPE & PURPOSE

Monroe County (County) is proposing to fortify the Long Key Transfer Station within and adjacent to parcels 00098460-000000 and 00098710-000000. The project is part of the County’s effort to protect critical infrastructure from storm damage by strengthening assets vulnerable to storm surge.

Current conditions include a riprap fortified shoreline and wetland fringe. The proposed work consists of repairing the existing riprap shoreline, restoring storm damaged areas of the wetland fringe through native wetland plantings, and installing wave attenuation devices.

WSP USA, Inc. (WSP) has been contracted by Monroe County to provide permitting and ecological assessment services for the duration of this project. This report intends to define the existing on-site environmental conditions including sensitive regulated benthic resources, wetland extent, and vegetation as defined in 62-312 F.A.C., 62-340 F.A.C., and the Florida Keys National Marine Sanctuary Resource Assessment Survey Protocols for Nearshore Construction Projects Version November 30, 2022 (FKNMS Survey Protocols-November 30, 2022).

A wetland delineation was performed to identify the landward extent of wetlands and locate the federal jurisdictional line using the methods and requirements defined in 62-340 F.A.C. Mangrove fringe and saltmarsh were detected and have been summarised in Section 3.2.

All location data was collected using a Trimble Geo 7X equipped with the Centimeter Accuracy Edition software package. Data collected in the field was then post-processed using GPS Pathfinder Office to further increase location accuracy. Project maps contained within this report were created using Esri ArcGIS Pro.

1.2 SITE HISTORY

1.2.1 OVERVIEW

The proposed project area consists of 2 parcels (00098460-000000 and 00098710-000000) located approximately 16 miles north of Marathon, Florida. The parcels are bounded to the east and west by US-1 and Florida Bay respectively and experiences moderate to high boat and vehicle traffic of vacationers and fisherman traveling to and from the Florida Keys. The transfer station allows visitors to enter the property and dispose of residential solid waste on site.

The survey encompassed approximately 0.39 acres of wetlands. The survey area begins along the service road adjacent to the shoreline and extends to the mean high-water line. The proposed project scope is limited to the survey area.

Figure 1: Location Map

1.2.2 PROJECT SITE - PARCELS 00098460-000000 AND 00098710-000000

The site consists of established solid waste facilities. On site, waste is prepared for transportation and disposal at facilities outside Monroe County. The facility has existing landfills surrounded by service roads. The property is owned by Monroe County and has an existing riprap fortified shoreline and wetland fringe spanning most of the survey area.

2 METHODOLOGY

2.1 ECOLIGICAL SURVEY

On March 26, 2025, WSP scientists conducted a survey of the proposed project area to document the terrestrial vegetation community (landward of the apparent mean-high water line) using the methods defined within Chapter 62-340 of the Florida Administrative Code Data Form Guide to be included within the permitting package. The survey area consisted of approximately 0.4 acres of mangrove fringe, saltwater marsh wetlands, and mixed species uplands. The survey was conducted by a two-person team to ensure safety and accuracy of data. Location data was collected using a Trimble Geo 7X equipped with the Centimeter Accuracy Edition software package. Data collected in the field was then post-processed using GPS Pathfinder Office and Esri ArcGIS Pro to further increase spatial accuracy. Survey design and methodology included:

• Complete a desktop review of the proposed survey area using aerial imagery.

• Conduct a comprehensive on-site survey to describe the vegetation community within the proposed project area.

• Post process data collected using Pathfinder Office and Esri ArcGIS Pro.

• Summarize the findings within a biological report.

2.1.1 DATA COLLECTION & ANALYSIS

On March 26, 2025 WSP staff surveyed the portion of the proposed project area waterward of the mean-high water line to the edge of Card Sound Road to document the vegetation community for use during project design and submitted as part of the permitting package. Location data was collected using a Trimble Geo 7X equipped with the Centimeter Accuracy Edition software package.

Data collected in the field was then post-processed using GPS Pathfinder Office and Esri ArcGIS Pro to further increase spatial accuracy. The results of the vegetation survey have been depicted in Figures 3 & 4.

3 SITE CONDITIONS

3.1 ECOLOGICAL SURVEY

The assessment areas consisted of approximately 0.4 acres of saltwater marsh. Riprap had been previously installed along the waterward edge of the road running parallel to the shore with staff noting areas with a slope greater than the 2:1 recommended. WSP scientists delineated the extent of wetlands while noting areas suitable for native plantings.

The wetland line follows the toe of the existing riprap (Figure 4) and consisted primarily of herbaceous obligate wetland flora interspersed with mature black and white mangrove (Avicennia germinans, Laguncularia racemosa) fringe (Figure 3). Gaps within the mangrove fringe where delineated as suitable for mangrove restoration plantings for erosion prevention as well as storm mitigation.

WSP staff also documented several species classified as Category I invasive by the Florida Invasive Species Council (FISC) most notable among them Seaside Mahoe (Thespesia populnea) and Brazilian Pepper (Schinus terebinthifolia). Category I invasives are especially problematic as they have been documented to quickly spread, establish dense monocultures, and displace native plant communities.

WSP staff were notified of the presence of a resident American Crocodile (Crocodylus acutus) by Monroe County staff. Monroe County staff described the crocodile as having lived within on of the saltwater marsh ponds south of the proposed construction site. Although the individual wasn’t observed by WSP staff, it’s important to note the presence of the federally and state listed species and ensure necessary steps are taken to ensure minimal impact during the construction phase of the project.

Endangered species This resource list is for informational purposes only and does not constitute an analysis of project level impacts.

The primary information used to generate this list is the known or expected range of each species.

Additional areas of influence (AOI) for species are also considered. An AOI includes areas outside of the species range if the species could be indirectly affected by activities in that area (e.g., placing a dam upstream of a fish population even if that fish does not occur at the dam site, may indirectly impact the species by reducing or eliminating water flow downstream). Because species can move, and site conditions can change, the species on this list are not guaranteed to be found on or near the project area. To fully determine any potential effects to species, additional site-specific and project-specific information is often required.

Section 7 of the Endangered Species Act requires Federal agencies to "request of the Secretary information whether any species which is listed or proposed to be listed may be present in the area of such proposed action" for any project that is conducted, permitted, funded, or licensed by any Federal agency. A letter from the local office and a species list which fulfills this requirement can only be obtained by requesting an official species list from either the Regulatory Review section in IPaC (see directions below) or from the local field office directly.

For project evaluations that require USFWS concurrence/review, please return to the IPaC website and request an official species list by doing the following:

1. Draw the project location and click CONTINUE.

2. Click DEFINE PROJECT.

3. Log in (if directed to do so).

4. Provide a name and description for your project.

5. Click REQUEST SPECIES LIST.

Listed species and their critical habitats are managed by the Ecological Services Program of the U.S. Fish and Wildlife Service (USFWS) and the fisheries division of the National Oceanic and Atmospheric Administration (NOAA Fisheries ).

Species and critical habitats under the sole responsibility of NOAA Fisheries are not shown on this list. Please contact NOAA Fisheries for species under their jurisdiction.

1. Species listed under the Endangered Species Act are threatened or endangered; IPaC also shows species that are candidates, or proposed, for listing. See the listing status page for more information. IPaC only shows species that are regulated by USFWS (see FAQ).

There are Bald Eagles and/or Golden Eagles in your project area.

Measures for Proactively Minimizing Eagle Impacts For information on how to best avoid and minimize disturbance to nesting bald eagles, please review the National Bald Eagle Management Guidelines. You may employ the timing and activity-specific distance recommendations in this document when designing your project/activity to avoid and minimize eagle impacts. For bald eagle information specific to Alaska, please refer to Bald Eagle Nesting and Sensitivity to Human Activity.

The FWS does not currently have guidelines for avoiding and minimizing disturbance to nesting Golden Eagles. For site-specific recommendations regarding nesting Golden Eagles, please consult with the appropriate Regional Migratory Bird Office or Ecological Services Field Office.

If disturbance or take of eagles cannot be avoided, an incidental take permit may be available to authorize any take that results from, but is not the purpose of, an otherwise lawful activity. For assistance making this determination for Bald Eagles, visit the Do I Need A Permit Tool. For assistance making this determination for golden eagles, please consult with the appropriate Regional Migratory Bird Office or Ecological Services Field Office.

Ensure Your Eagle List is Accurate and Complete If your project area is in a poorly surveyed area in IPaC, your list may not be complete and you may need to rely on other resources to determine what species may be present (e.g. your local FWS field office, state surveys, your own surveys). Please review the Supplemental Information on Migratory Birds and Eagles, to help you properly interpret the report for your specified location, including determining if there is sufficient data to ensure your list is accurate.

For guidance on when to schedule activities or implement avoidance and minimization measures to reduce impacts to bald or golden eagles on your list, see the "Probability of Presence Summary" below to see when these bald or golden eagles are most likely to be present and breeding in your project area.

Probability of Presence Summary

The graphs below provide our best understanding of when birds of concern are most likely to be present in your project area. This information can be used to tailor and schedule your project activities to avoid or minimize impacts to birds. Please make sure you read "Supplemental Information on Migratory Birds and Eagles", specifically the FAQ section titled "Proper Interpretation and Use of Your Migratory Bird Report" before using or attempting to interpret this report.

Probability of Presence ( )

Each green bar represents the bird's relative probability of presence in the 10km grid cell(s) your project overlaps during a particular week of the year. (A year is represented as 12 4-week months.) A taller bar indicates a higher probability of species presence. The survey effort (see below) can be used to establish a level of confidence in the presence score. One can have higher confidence in the presence score if the corresponding survey effort is also high.

How is the probability of presence score calculated? The calculation is done in three steps:

1. The probability of presence for each week is calculated as the number of survey events in the week where the species was detected divided by the total number of survey events for that week. For example, if in week 12 there were 20 survey events and the Spotted Towhee was found in 5 of them, the probability of presence of the Spotted Towhee in week 12 is 0.25.

2. To properly present the pattern of presence across the year, the relative probability of presence is calculated. This is the probability of presence divided by the maximum probability of presence across all weeks. For example, imagine the probability of presence in week 20 for the Spotted Towhee is 0.05, and that the probability of presence at week 12 (0.25) is the maximum of any week of the year. The relative probability of presence on week 12 is 0.25/0.25 = 1; at week 20 it is 0.05/0.25 = 0.2.

3. The relative probability of presence calculated in the previous step undergoes a statistical conversion so that all possible values fall between 0 and 10, inclusive. This is the probability of presence score.

To see a bar's probability of presence score, simply hover your mouse cursor over the bar.

Breeding Season ( ) Yellow bars denote a very liberal estimate of the time-frame inside which the bird breeds across its entire range. If there are no yellow bars shown for a bird, it does not breed in your project area.

Survey Effort ( )

Bald Eagle Haliaeetus leucocephalus This is not a Bird of Conservation Concern (BCC) in this area, but warrants attention because of the Eagle Act or for potential susceptibilities in offshore areas from certain types of development or activities.

Bald & Golden Eagles FAQs

What does IPaC use to generate the potential presence of bald and golden eagles in my specified location?

The potential for eagle presence is derived from data provided by the Avian Knowledge Network (AKN). The AKN data is based on a growing collection of survey, banding, and citizen science datasets and is queried and filtered to return a list of those birds reported as occurring in the 10km grid cell(s) which your project intersects, and that have been identified as warranting special attention because they are an eagle (Bald and Golden Eagle Protection Act requirements may apply).

Proper interpretation and use of your eagle report On the graphs provided, please look carefully at the survey effort (indicated by the black vertical line) and for the existence of the "no data" indicator (a red horizontal line). A high survey effort is the key component. If the survey effort is high, then the probability of presence score can be viewed as more dependable. In contrast, a low survey effort line or no data line (red horizontal) means a lack of data and, therefore, a lack of certainty about presence of the species. This list is not perfect; it is simply a starting point for identifying what birds have the potential to be in your project area, when they might be there, and if they might be breeding (which means nests might be present). The list and associated information help you know what to look for to confirm presence and helps guide you in knowing when to implement avoidance and minimization measures to eliminate or reduce potential impacts from your project activities or get the appropriate permits should presence be confirmed.

How do I know if eagles are breeding, wintering, or migrating in my area?

To see what part of a particular bird's range your project area falls within (i.e. breeding, wintering, migrating, or resident), you may query your location using the RAIL Tool and view the range maps provided for birds in your area at the bottom of the profiles provided for each bird in your results. If an eagle on your IPaC migratory bird species list has a breeding season associated with it (indicated by yellow vertical bars on the phenology graph in

If "Breeds elsewhere" is indicated, then the bird likely does not breed in your project area.

Interpreting the Probability of Presence Graphs

Each green bar represents the bird's relative probability of presence in the 10km grid cell(s) your project overlaps during a particular week of the year. A taller bar indicates a higher probability of species presence. The survey effort can be used to establish a level of confidence in the presence score.

How is the probability of presence score calculated? The calculation is done in three steps:

The probability of presence for each week is calculated as the number of survey events in the week where the species was detected divided by the total number of survey events for that week. For example, if in week 12 there were 20 survey events and the Spotted Towhee was found in 5 of them, the probability of presence of the Spotted Towhee in week 12 is 0.25.

To properly present the pattern of presence across the year, the relative probability of presence is calculated.

This is the probability of presence divided by the maximum probability of presence across all weeks. For example, imagine the probability of presence in week 20 for the Spotted Towhee is 0.05, and that the probability of presence at week 12 (0.25) is the maximum of any week of the year. The relative probability of presence on week 12 is 0.25/0.25 = 1; at week 20 it is 0.05/0.25 = 0.2.

The relative probability of presence calculated in the previous step undergoes a statistical conversion so that all possible values fall between 0 and 10, inclusive. This is the probability of presence score.

Breeding Season () Yellow bars denote a very liberal estimate of the time-frame inside which the bird breeds across its entire range.

If there are no yellow bars shown for a bird, it does not breed in your project area.

Survey Effort () Vertical black lines superimposed on probability of presence bars indicate the number of surveys performed for that species in the 10km grid cell(s) your project area overlaps.

No Data () A week is marked as having no data if there were no survey events for that week.

Survey Timeframe Surveys from only the last 10 years are used in order to ensure delivery of currently relevant information. The exception to this is areas off the Atlantic coast, where bird returns are based on all years of available data, since data in these areas is currently much more sparse.

Measures for Proactively Minimizing Migratory Bird Impacts

Your IPaC Migratory Bird list showcases birds of concern, including Birds of Conservation Concern (BCC), in your project location. This is not a comprehensive list of all birds found in your project area. However, you can help proactively minimize significant impacts to all birds at your project location by implementing the measures in the Nationwide avoidance and minimization measures for birds document, and any other project-specific avoidance and minimization measures suggested at the link Measures for avoiding and minimizing impacts to birds for the birds of concern on your list below.

Ensure Your Migratory Bird List is Accurate and Complete

If your project area is in a poorly surveyed area, your list may not be complete and you may need to rely on other resources to determine what species may be present (e.g. your local FWS field office, state surveys, your own surveys). Please review the Supplemental Information on Migratory Birds and Eagles document, to help you properly interpret the report for your specified location, including determining if there is sufficient data to ensure your list is accurate.

For guidance on when to schedule activities or implement avoidance and minimization measures to reduce impacts to migratory birds on your list, see the "Probability of Presence Summary" below to see when these birds are most likely to be present and breeding in your project area.

Each green bar represents the bird's relative probability of presence in the 10km grid cell(s) your project overlaps during a particular week of the year. (A year is represented as 12 4-week months.) A taller bar indicates a higher probability of species presence. The survey effort (see below) can be used to establish a level of confidence in the presence score. One can have higher confidence in the presence score if the corresponding survey effort is also high.

How is the probability of presence score calculated? The calculation is done in three steps:

1. The probability of presence for each week is calculated as the number of survey events in the week where the species was detected divided by the total number of survey events for that week. For example, if in week 12 there were 20 survey events and the Spotted Towhee was found in 5 of them, the probability of presence of the Spotted Towhee in week 12 is 0.25.

2. To properly present the pattern of presence across the year, the relative probability of presence is calculated. This is the probability of presence divided by the maximum probability of presence across all weeks. For example, imagine the probability of presence in week 20 for the Spotted Towhee is 0.05, and that the probability of presence at week 12 (0.25) is the maximum of any week of the year. The relative probability of presence on week 12 is 0.25/0.25 = 1; at week 20 it is 0.05/0.25 = 0.2.

3. The relative probability of presence calculated in the previous step undergoes a statistical conversion so that all possible values fall between 0 and 10, inclusive. This is the probability of presence score.
