Kenmar Road and S. Fortuna Boulevard/Ross Hill Road Intersection 5 1. INTRODUCTION
Project Description
The project proposes to improve traffic, pedestrian, and bicycle operations at the intersection of Kenmar Road and S. Fortuna Boulevard/Ross Hill Road in Fortuna in Humboldt County, California. The existing intersection controls, roadway geometry, and the high volumes of local and regional traffic result in poor traffic operation at and near the intersection. Proposed project components include a roundabout at the intersection as well as crosswalks and sidewalks for pedestrians. Refer to Figure 1 and Attachment A for a location map.

The full closure of the Drake Hill Road intersection with US 101 in 2010 resulted in an increase in traffic volume to the US 101-Kenmar Road interchange and the Kenmar Road and S. Fortuna Boulevard/Ross Hill Road Intersection. The additional traffic volume contributed operational issues and safety concerns at the intersection.

Improvements to the Kenmar Road and S. Fortuna Boulevard/Ross Hill Road intersection were identified as a priority project in the City of Fortunas 2021 Local Road Safety Plan (LRSP).

2. BACKGROUND
Existing Conditions
The project study area is focused on the intersection of Kenmar Road and S. Fortuna Boulevard/Ross Hill Road. Along Kenmar Road from Eel River Drive and Renee Avenue and along S. Fortuna Boulevard/Ross Hill Road from 400 feet north of the intersection to 700 feet south of the intersection.

Refer to Figure 2 for the existing intersection configuration, control and traffic counts.

Kenmar Road is 100 feet wide on the west side of the intersection with an eastbound through-left lane, and a right turn lane. On the east side of the intersection, Kenmar Road is the same configuration with a westbound through-left lane, and a right turn lane. West of the intersection Kenmar Road is listed as an Other Principal Arterial per the California Road System (CRS) – Functional Classification. East of the intersection Kenmar Road is a major collector.

City of Fortuna
Kenmar Road and S. Fortuna Boulevard/Ross Hill Road Intersection 6 Ross Hill Road is the south leg of the intersection and is 55 feet wide at the intersection with a northbound left turn lane, a through lane, and a through-right lane. S. Fortuna Boulevard is the north leg of the intersection and is 55 feet wide at the intersection with a southbound left turn lane, two through lanes, and a right turn slip-lane that begins approximately 250 feet north of the intersection. Per the CRS, Ross Hill Road is classified as a Minor Arterial and S. Fortuna Boulevard is classified as an Other Principal Arterial.

Also, according to CRS, S. Fortuna Boulevard, and Kenmar Road east of the intersection, are both part of the National Highway System (NHS).

Purpose:
• Simplify and improve navigation and traffic operations through the Kenmar Road and S. Fortuna Boulevard/Ross Hill Road intersection;
• Improve operations, reduce congestion, and minimize conflicts intersection; • Improve intersection safety; and
• Improve bicycle and pedestrian facilities through the intersection.

Need:
• Poor traffic operations and safety concerns resulting from high volumes and insufficient storage; and
• Limited bicycle and pedestrian facilities resulting in a barrier to bicycle and pedestrian circulation and connectivity.

4. TRAFFIC ENGINEERING PERFORMANCE ASSESSMENT
This section provides the results of the operations analysis for the intersection of Kenmar Road and S.

Fortuna Boulevard/Ross Hill Road & Kenmar Road. The term project as used in this section refers to the intersection improvements being proposed for the study intersection.

Traffic Operations
A traffic operations analysis was prepared by GHD Inc. to analyze the existing and future performance of the Kenmar Road and S. Fortuna Boulevard/Ross Hill Road intersection. The operational analysis used the traffic counts that were collected in March 2016 for the Highway 101, Fortuna Downtown and Riverwalk Area Complete Streets and Connectivity Planning Study. These counts were adjusted upwards utilizing growth factors to reflect Year 2022, 2025, and 2045 traffic volumes. Year 2022 represents existing conditions that are experienced in the AM and PM peak hour. Year 2025 volumes represent Opening Year conditions after the stated improvements are expected to be built. Year 2045 volumes represent the design year approximately 20 years in the future after intersection improvements are completed.

The growth rate applied to Year 2016 counts to develop Year 2022, 2025, and 2045 volumes was provided by the City of Fortuna General Plan. The growth rate was identified as 1.6% per year. Applying this growth rate over a 6-, 9-, and 29-year period yields growth rates of 10%, 15%, and 47%, respectively.

The operations analysis utilized the following technical parameters:
• Peak Hour Factor (PHF) comes from traffic counts. Based on information obtained from traffic counts, the PHF was determined to be 0.84 for AM and 0.99 for the PM peak hours. • The environmental factor in SIDRA was based on the guidelines provided by Caltrans memorandum titled SIDRA Settings and Related Parameters for US HCM and SIDRA Roundabout Capacity Model (Dec 20, 2017). Based on the guidelines, environmental factors have been set for 1.05 for design year conditions.
• A peak hour truck percentage for the study intersection was estimated to be 2% for the AM and PM peak hours.
• Signal analysis was performed in Synchro 11 for the LOS and SimTraffic for the queues. • Roundabout analysis was performed in Sidra 9 for both the LOS and Queues.

The following three alternatives were analyzed in the operations analysis:
• Existing Conditions (No Project).
• Signal Alternative (including Minimum Build, opening year 2025). • Roundabout Alternative.

Note: Values in red indicate queue exceeds available storage length As indicated in the table above, the intersection currently operates at LOS D in the AM peak hour and LOS C in the PM peak hour. LOS D indicates that traffic conditions are approaching an unstable flow with high delays. As the LOS is currently a mid-D, it will worsen to an LOS E in the future. Additionally, the intersection has the following movements that have current 95th percentile queues that exceed available storage (as indicated by the red text in the Table 2):
• AM Peak Hour
o Northbound Left
• PM Peak Hour
o Eastbound Right
Full Build Conditions
The full build conditions refer to an analysis scenario in which the identified improvement(s) were built.

Two different improvements were analyzed in this scenario. The first improvement was to improve the existing signal with additional lane channelization’s, turn pocket extensions to provide improved operations. The second improvement was to convert the signalized intersection to a roundabout controlled intersection.

City of Fortuna
Kenmar Road and S. Fortuna Boulevard/Ross Hill Road Intersection 9 Signal Alternative (including Minimum Build)
The signal alternative analyzed the current signalized intersection with the addition of key improvements that would provide improved conditions over “No Build” for the AM and PM peak hours.

Opening Year 2025 (Minimum Build)
Under Year 2025 conditions, an additional eastbound left turn pocket of 300 feet was added, converting the existing left/through lane to a through only, and the westbound approach was re-striped to convert the left/through lane and right turn pocket to a left turn pocket and through/right lane. This lane addition and restriping allows for an update to the signal timing plan that provides full phasing for the eastbound and westbound approaches instead of the existing split phases. To keep within the existing paved footprint and not extend into the creek for the extra lane, eliminating the southbound right slip lane may be necessary. The signal would then need to be modified to have a southbound right at the intersection.

Tables 3 and 4 present the Opening Year level of service and 95th percentile queues for the AM and PM peak hours.

Notes: Values in red indicate queue exceeds available storage length As presented in the tables above with the addition of a second eastbound left turn pocket, the intersection is projected to operate at LOS D for the AM and LOS C for the PM peak hours. This build alternative also greatly reduces the eastbound queue lengths compared to the existing condition. The 95th percentile queues for the following turning movement is projected to exceed the available storage:
• Southbound Left
• Southbound Right
City of Fortuna
Kenmar Road and S. Fortuna Boulevard/Ross Hill Road Intersection 10 The eastbound and northbound queues are projected to be within the available storage.

Design Year 2045 (Full Build)
Year 2045 refers to an analysis scenario approximately 23 years in the future as is known as the Design Year. The improvements identified to provide stable intersection operations are the following:
• A second northbound left turn pocket. This will require a receiving (second) lane on the west side of the intersection.
• Provide a 300-foot protected left turn pocket, a through lane and a 100-foot right lane for Eastbound approach, same as the 2025 minimum build scenario. • Provide a 100-foot left turn pocket, a through lane and a 100-foot right lane for Westbound approach.
• Convert split phase to protected left turn phasing for Eastbound and Westbound approaches, same as in the 2025 minimum build scenario.
• Extend the left turn pocket for the southbound approach to 120-feet. • Remove the Channelization from the southbound right pocket and extend the storage length to 200 feet.

City of Fortuna
Kenmar Road and S. Fortuna Boulevard/Ross Hill Road Intersection 11 As presented in the tables on the previous page with the identified improvements, the intersection is projected to operate at LOS C for the AM and PM peak hours. As it operates acceptably in the design year, it would also operate acceptably in the opening year if it were constructed in place of the 2025 minimum build. The 95th percentile queues for the following turning movement are projected to exceed the available storage:
• Westbound Right
• Southbound Right
The eastbound and northbound queues are projected to be well within the available storage.

Roundabout Alternative
The roundabout alternative would convert the signalized intersection to a four-legged roundabout intersection.

Kenmar Road and S. Fortuna Boulevard/Ross Hill Road Intersection 13 Traffic Collision Analysis
Collision data for the City of Fortuna was gathered using the Statewide Integrated Traffic Records System (SWITRS), Transportation Injury Mapping System (TIMS), and collision data from the Fortuna Police Department. Each data set was analyzed, crosschecked, and compiled into one complete comprehensive data set. This process was done to ensure that all reported collisions occurring at the project location are accounted for and to provide additional information that one system may not have captured. The data set analyzed contains collisions between January 1, 2015, and December 31, 2019 (5 years).

During this period, a total of 14 collisions were reported. Many of these collisions were rear ends and low severity. Intersection congestion can increase the likelihood of rear end collisions as there are more vehicles operating in a specific area. A summary of the collisions is shown in Table 9 below.

5. DEFICIENCIES
The existing conditions analysis shows that the intersection is operating below a LOS of C (below Fortuna’s minimum standard). The tables above also show that currently there is not enough storage to meet the peak hour demands on multiple legs of the intersection. In the AM peak hour, the northbound left turn lane has 95th percentile queues that exceed the available storage. In the PM peak hour, the eastbound right turn and the southbound left turn have 95th percentile queues that exceed the available storage.

The poor level of service and intersection congestion may be contributing to the number of rear end collisions occurring at the intersection.

The existing intersection also lacks adequate pedestrian and bicycle facilities.

6. CORRIDOR AND SYSTEM COORDINATION
The following discussion highlights the state, regional and local planning considerations for the proposed project improvements.

State Planning
Complete Streets
Caltrans Director Policy 37 (DP-37) requires in locations with current and/or future pedestrian, bicycle, or transit needs, all transportation projects funded or overseen by Caltrans to provide comfortable, convenient, and connected complete streets facilities for people walking, biking, and taking transit or passenger rail unless an exception is documented and approved.

Regional Planning
The City of Fortuna plans to add the project to the next update of the Humboldt County Associations of Governments (HCAOG) Regional Transportation Plan (RTP).

City of Fortuna
Kenmar Road and S. Fortuna Boulevard/Ross Hill Road Intersection 14 Local Planning
General Plan
The City of Fortuna General Plan 2030 (General Plan) formalizes a long-term vision for the City’s physical development. The Kenmar Road and S. Fortuna Boulevard/Ross Hill Road intersection improvements would fulfill many policies set forth in the General Plan, including the policies are detailed below.

Roadways and Highways
Policy TC-1.1 Reducing Mode Conflicts – The City shall seek to minimize conflicts between pedestrians, automobiles, and bicycles.

Policy TC-1.2 New Roadway Improvements – The City shall design and phase roadway improvements so that a level of service (LOS) C or better is maintained on all City streets, except that LOS D or better shall be maintained on Main Street.

Policy TC-1.3 Balanced Transportation System – The City shall strive to meet the level of service standard through a balanced transportation system that provides alternatives to the automobile and by promoting pedestrian, bicycle, and transit connections between employment areas and major residential and commercial areas.

Policy TC-1.4 Improved LOS – The City shall identify economic, design, and planning solutions to improve levels of service currently below LOS C. Where physical mitigation is infeasible, the City shall consider developing programs that enhance alternative access or otherwise reduce automobile travel demand.

Bicycle and Trail Facilities
Policy TC-5.2 Bicycle System – The City shall develop and maintain a safe, convenient, and effective bicycle system that encourages increased bicycle use.

Pedestrian Facilities
Policy TC-4.2 New Developments – The City shall continue to require new development to finance and install sidewalks and pedestrian pathways connecting them to existing sidewalks or widening the right-of-way fronting the development to accommodate new sidewalks.

Policy TC-4.3 Specific Plans – The City shall encourage specific development plans to include design continuity of pedestrian access that enables residents to walk from their homes to places of work, recreation, and shopping.

Local Road Safety Plan
Improvements to the Kenmar Road and S. Fortuna Boulevard/Ross Hill Road intersection were identified as a priority project in the City of Fortuna’s 2021 LRSP.

7. ALTERNATIVES
Unless noted otherwise, the alternatives identified below address the purpose and need of the project.

The "No Build" Alternative
This is the "No Build" condition, where the study intersections would remain unaltered with respect to intersection geometrics and stop control. This alternative does not meet the purpose and need.

Signal (including Minimum Build) Alternative
As a supplement to the adjacent on-going US101/Kenmar Road interchange project to the west of this intersection, it may become necessary to support potential queuing going eastbound into the intersection.

As such, a minimum build signal alternative that provides an extended left turn lane and new right turn lane with a bike lane has been provided. This alternative could potentially be further modified to eliminate the existing southbound slip right, dependent on timing of improvements and availability of funding. See City of Fortuna
Kenmar Road and S. Fortuna Boulevard/Ross Hill Road Intersection 15 Attachment B for conceptual drawings of the minimum build signal alternative with and without the current adjacent interchange geometrics for context.

The full build signal alternative would add a second left turn lane heading north on Ross Hill Road. This would reduce wait times and provide more storage for cars turning left. The west leg of Kenmar Road would be widened to add another receiving lane for the two left turn lanes on Ross Hill Road. The East leg of Kenmar Road would also be widened to provide for a bike lane. The bike lane addition would change the lane configuration at the intersection separating the right turn lane from the through lane with the bike lane. This alternative also includes bicycle facilities for all legs of the intersections providing connectivity to cyclists in the area. See Attachment B for conceptual drawings of the full build signal alternative with and without the current adjacent interchange geometrics for context.

Although the full build signal alternative does offer several operational and safety improvements compared to the no build, the full build signal alternative would provide inferior intersection operations compared to the roundabout alternative and would require substantial geometric changes to accommodate and provide improved operations for Year 2025 and 2045 conditions.

Note that in order to accommodate the required lane configurations on Kenmar Road, west of the intersection, the existing box culvert on Mill Creek would need to be extended or replaced, and approximately 250 feet of the Mill Creek channel north of Kenmar Road would need to be relocated.

These required culvert and channel modifications would likely face significant regulatory challenges, including the need to provide for fish passage through the culvert crossing. Before advancing with the alternative, consultation with regulatory agencies should occur to ensure to ensure that work would be allowable.

Roundabout Alternative
The roundabout alternative would provide increased safety and circulation for the intersection.

Roundabouts reduce speed at intersections which reduces the impact intensity of collisions that occur; they also reduce the number of potential conflict/collision points at the intersection. With the roundabout alternative, the available movements at the intersection have been maintained, while the number of lanes has been reduced. The roundabout alternative includes pedestrian crossings on each leg of the intersection providing connectivity to existing facilities to help close the gap in pedestrian facilities. Bicycle ramps and paths are also proposed for each leg of the roundabout allowing cyclists to travel through the intersection without entering the roundabout if they feel more comfortable being physically separated from the cars. See Attachment B for conceptual drawings of the roundabout alternative.

The roundabout alternative would provide better intersection operations compared to the signal alternative, as well as acceptable 95th percentile queues through Design Year 2045. The roundabout alternative would provide a single lane approach in the southbound, eastbound, and westbound directions with dedicated right turn pockets. The northbound approach would require a dedicated left turn lane with a through-right lane due to the heavy demand to the US 101 highway interchange to the west.

Cost Estimates
Capital, support, and total estimated costs for each alternative are summarized in Table 10 on the following page. The costs presented are escalated to the expected year of expenditure. The total capital costs include traffic control, mobilization, right-of-way, utility relocation, and contingencies. The total support costs include costs for environmental clearance, plans, specifications, and estimates (PS&E), right-of-way engineering and acquisitions, and construction support and management. Costs for the Minimum Build signal differ from the alternative shown in Attachment B and are based on the smallest potential footprint for the alternative, which would not include a realigned southbound slip lane, but rather a new southbound right that would be added as part of the westbound thru realignment/widening. Refer to Attachment F for detailed costs estimates for each alternative.

8. RIGHT-OF-WAY
Right-of-Way
The initial conceptual design relied on assessor parcel lines to approximate the public right-of-way and property lines as existing survey-level right-of-way information was not available at the time of this study.

Refer to Attachment C for copies of the assessor parcel maps for the project area.

Based on the assessor parcel lines, it appears that both the signal and roundabout alternatives can be constructed entirely within the existing City right of way with the exception of one discrete location northeast of the project intersection (APN # 202-021-004).

If the project advances, research should be conducted to determine accurate right-of-way widths, property lines, parcel ownerships, and maintenance responsibilities. Right-of-Way Data Sheets will need to be prepared during the right-of-way phase of the project.

In addition to permanent acquisitions, temporary permissions/easements and/or encroachment permits will need to be obtained during the Right-of-Way phase of the project.

Existing underground and above ground utilities in the vicinity of the project may need to be modified or relocated to accommodate the proposed improvements. The relocation of non-City owned utilities is not expected to be required. During the Project Approval and Environmental Document (PA&ED) phase the City should request utility mapping from the utility companies identified in Table 11 and identify potential conflicts with the proposed work.

Railroad
A railroad corridor owned by the Great Redwood Trail Agency (formerly North Coast Railroad Authority) roughly parallels the east side of US 101 and crosses through Kenmar Road East of the project area. At the time of this study the railroad corridor was in the process of being railbanked, allowing the corridor to be utilized for a trail system until rail operation become viable. There are no railroad facilities in the project area.

City of Fortuna
Kenmar Road and S. Fortuna Boulevard/Ross Hill Road Intersection 17 9. STAKEHOLDER INVOLVEMENT
As part of the outreach conducted to support the development of the City of Fortuna’s 2021 LRSP, the City solicited public input on road safety concerns through an online interactive map and a survey. The Kenmar Road and S. Fortuna Boulevard/Ross Hill Road intersection received some of the most comments on the City’s online interactive map. The common comment theme for the project intersection were as follows:
• Merging onto Kenmar Road from S. Fortuna Boulevard
• Red light running
According to the results of the public survey, the primary safety concern in the City of Fortuna is intersections, followed by a lack of infrastructure (sidewalks, bike lanes, turn lanes, etc.). Refer to Figure 4 below for a chart of all responses provided. Both of these items have been identified as specific needs for this project.

10. ENVIRONMENTAL COMPLIANCE
Preliminary Environmental Analysis
In 2022, an initial environmental evaluation of the project and alternatives was conducted to help anticipate potential environmental constraints that may affect project design, alternatives, cost, schedule, and delivery. The evaluation included a reconnaissance-level site investigation of existing conditions in the project area to identify the presence or potential presence of biological resources listed under the Federal Endangered Species Act (ESA), the presence of wetlands and Waters of the US as regulated by the US Army Corps of Engineers (USACE), the presence or potential presence of species listed as endangered or threatened under the California Endangered Species Act (CESA) or considered a species of special concern (SSC) by the California Department of Fish and Wildlife (CDFW), or the potential for special-status plant species having a rare plant ranking as determined by the California Native Plant Society (CNPS) rare plant inventory, and to present the potential of sensitive habitats as listed by the CDFW. A map of the potential environmental constraints is included in Attachments D.

NEPA, CEQA and Permitting
During the PA&ED phase, the project will need to be evaluated for potential impacts on the environment in compliance with the California Environmental Quality Act (CEQA) and National Environmental Policy Act (NEPA). Feasible opportunities to avoid or reduce impacts will need to be pursued and mitigation City of Fortuna
Kenmar Road and S. Fortuna Boulevard/Ross Hill Road Intersection 18 measures developed to reduce potentially significant impacts as appropriate. The draft CEQA document would be made available to the public for review and comment.

Based on the information currently available, the expected compliance pathways are a Mitigated Negative Declaration of environmental impact for CEQA and a Categorical Exclusion for NEPA in conformance with the Federal Highways Administration/Caltrans programmatic process.

During the initial environmental evaluation, potential riparian habitat was identified along the Kenmar Road, South Fortuna Road, and Ross Hill Road margins. This potential riparian habitat is largely associated with Mill Creek, which crosses under Ross Hill Road via a 72 inch culvert and under Kenmar Road via a ten foot by five foot box culvert. Potential wetlands were identified in the upland ditch island between Kenmar Road and South Fortuna Boulevard, along with a ditch on the south side of Kenmar Road.

Mill Creek is an anadromous waterway. Replacement or alteration of the two Mill Creek culverts could affect special status anadromous salmonids and other aquatic organisms. Sediment and erosion control Best Management Practices would need to be implemented during construction to reduce the likelihood of impacts to Mill Creek and aquatic organisms.

The wetland and riparian habitats in the project area have a moderate to high likelihood of supporting listed reptile, frog and fish species including Western Pond Turtle Emys (Actinymys) marmorata, Northern Red-legged Frog Rana aurora, and Foothill Yellow-legged Frog Rana boylii, along with other special status species. Several sensitive plant species and Sensitive Natural Communities also have a moderate likelihood of occurring in the study area. The following database searches are included in Attachment E:
• California Natural Diversity Database
• Fortuna California Native Plant Society Database
• National Marine Fisheries Service Species List
• United States Fish and Wildlife Service Species List
Subsequent environmental investigations, including a wetland delineation, will be needed to be completed to identify any sensitive species and habitats in the project area, and to identify any necessary protection and minimization measures. Additionally, a variety of permits and related environmental review will be necessary for project planning and design.

Anticipated Environmental Permitting and Compliance Requirements are presented in Table 12.

The following technical studies and plans are anticipated to be required based on available information:
• Natural Environmental Study (NES) of Biological Resources • Wetland Delineation and Special Status Botanical Resources Survey • Initial Site Assessment (ISA)
• Visual Impact Assessment (VIA), Minor VIA, or Visual Technical Memorandum • Floodplain Evaluation & Location Hydraulic Study
• Geotechnical Investigation
• Historic Property Survey Report (HPSR) and Archaeological Survey Report (ASR) • Preliminary Hydraulics/Hydrology Study
Note that if the project does not include federal funds, several of the special studies noted above would not be required.

11. FUNDING
Funding to advance the project has not yet been programmed, however the City of Fortuna intends to request funding to advance the PA&ED phase of the project utilizing the funding from the State Transportation Improvement Program (STIP), the Active Transportation Program (ATP), the federal RAISE program, local funds, or an alternative funding source.

Because of the likely cost of the project, a portion of funding would likely be in the form of federal funds. It has been determined that this project is eligible for Federal-aid funding.

Capital Outlay Cost Estimate
Table 13 presents a summary of the escalated capital outlay estimates for the proposed alternatives.

IPaC resource list
This report is an automatically generated list of species and other resources such as critical habitat (collectively referred to as trust resources) under the U.S. Fish and Wildlife Service's (USFWS) jurisdiction that are known or expected to be on or near the project area referenced below. The list may also include trust resources that occur outside of the project area, but that could potentially be directly or indirectly a�ected by activities in the project area. However, determining the likelihood and extent of e�ects a project may have on trust resources typically requires gathering additional site-speci�c (e.g., vegetation/species surveys) and project-speci�c (e.g., magnitude and timing of proposed activities) information.

Below is a summary of the project information you provided and contact information for the USFWS o�ce(s) with jurisdiction in the de�ned project area. Please read the introduction to each section that follows (Endangered Species, Migratory Birds, USFWS Facilities, and NWI Wetlands) for additional information applicable to the trust resources addressed in that section.

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 in�uence (AOI) for species are also considered. An AOI includes areas outside of the species range if the species could be indirectly a�ected by activities in that area (e.g., placing a dam upstream of a �sh population even if that �sh does not occur at the dam site, may indirectly impact the species by reducing or eliminating water �ow 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 e�ects to species, additional site-speci�c and project-speci�c 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 o�ce and a species list which ful�lls this requirement can only be obtained by requesting an o�cial species list from either the Regulatory Review section in IPaC (see directions below) or from the local �eld o�ce directly.

For project evaluations that require USFWS concurrence/review, please return to the IPaC website and request an o�cial 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 �sheries 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).

2. NOAA Fisheries, also known as the National Marine Fisheries Service (NMFS), is an 1 2

Certain birds are protected under the Migratory Bird Treaty Act and the Bald and Golden Eagle Protection Act .

Any person or organization who plans or conducts activities that may result in impacts to migratory birds, eagles, and their habitats should follow appropriate regulations and consider implementing appropriate conservation measures, as described below.

1. The Migratory Birds Treaty Act of 1918.

2. The Bald and Golden Eagle Protection Act of 1940.

Additional information can be found using the following links:

The birds listed below are birds of particular concern either because they occur on the USFWS Birds of Conservation Concern (BCC) list or warrant special attention in your project location. To learn more about the levels of concern for birds on your list and how this list is generated, see the FAQ below. This is not a list of every bird you may �nd in this location, nor a guarantee that every bird on this list will be found in your project area. To see exact locations of where birders and the general public have sighted birds in and around your project area, visit the E-bird data mapping tool (Tip: enter your location, desired date range and a species on your list). For projects that occur o� the Atlantic Coast, additional maps and models detailing the relative occurrence and abundance of bird species on your list are available. Links to additional information about Atlantic Coast birds, and other important information about your migratory bird list, including how to properly interpret and use your migratory bird report, can be found below.

For guidance on when to schedule activities or implement avoidance and minimization measures to reduce impacts to migratory birds on your list, click on the PROBABILITY OF PRESENCE SUMMARY at the top of your list to see when these birds 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 and understand the FAQ "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 e�ort (see below) can be used to establish a level of con�dence in the presence score. One can have higher con�dence in the presence score if the corresponding survey e�ort 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.

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 E�ort ( )
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. The number of surveys is expressed as a range, for example, 33 to 64 surveys. probability of presence breeding season survey e�ort no data To see a bar's survey e�ort range, simply hover your mouse cursor over the bar.

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 o� the Atlantic coast, where bird returns are based on all years of available data, since data in these areas is currently much more sparse.

Tell me more about conservation measures I can implement to avoid or minimize impacts to migratory birds.

Nationwide Conservation Measures describes measures that can help avoid and minimize impacts to all birds at any location year round. Implementation of these measures is particularly important when birds are most likely to occur in the project area. When birds may be breeding in the area, identifying the locations of any active nests and avoiding their destruction is a very helpful impact minimization measure. To see when birds are most likely to occur and be breeding in your project area, view the Probability of Presence Summary. Additional measures or permits may be advisable depending on the type of activity you are conducting and the type of infrastructure or bird species present on your project site.

What does IPaC use to generate the migratory birds potentially occurring in my speci�ed location? The Migratory Bird Resource List is comprised of USFWS Birds of Conservation Concern (BCC) and other species that may warrant special attention in your project location.

The migratory bird list generated for your project 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 �ltered to return a list of those birds reported as occurring in the 10km grid cell(s) which your project intersects, and that have been identi�ed as warranting special attention because they are a BCC species in that area, an eagle (Eagle Act requirements may apply), or a species that has a particular vulnerability to o�shore activities or development.

Again, the Migratory Bird Resource list includes only a subset of birds that may occur in your project area. It is not representative of all birds that may occur in your project area. To get a list of all birds potentially present in your project area, please visit the AKN Phenology Tool.

What does IPaC use to generate the probability of presence graphs for the migratory birds potentially occurring in my speci�ed location?
The probability of presence graphs associated with your migratory bird list are based on data provided by the Avian Knowledge Network (AKN). This data is derived from a growing collection of survey, banding, and citizen science datasets .

Probability of presence data is continuously being updated as new and better information becomes available. To learn more about how the probability of presence graphs are produced and how to interpret them, go the Probability of Presence Summary and then click on the "Tell me about these graphs" link.

How do I know if a bird is breeding, wintering, migrating or present year-round in my project area? To see what part of a particular bird's range your project area falls within (i.e. breeding, wintering, migrating or year-round), you may refer to the following resources: The Cornell Lab of Ornithology All About Birds Bird Guide, or (if you are unsuccessful in locating the bird of interest there), the Cornell Lab of Ornithology Neotropical Birds guide. If a bird on your migratory bird species list has a breeding season associated with it, if that bird does occur in your project area, there may be nests present at some point within the timeframe speci�ed. If "Breeds elsewhere" is indicated, then the bird likely does not breed in your project area.

What are the levels of concern for migratory birds?
Migratory birds delivered through IPaC fall into the following distinct categories of concern:

1. "BCC Rangewide" birds are Birds of Conservation Concern (BCC) that are of concern throughout their range anywhere within the USA (including Hawaii, the Paci�c Islands, Puerto Rico, and the Virgin Islands);

2. "BCC - BCR" birds are BCCs that are of concern only in particular Bird Conservation Regions (BCRs) in the continental USA; and

3. "Non-BCC - Vulnerable" birds are not BCC species in your project area, but appear on your list either because of the Eagle Act requirements (for eagles) or (for non-eagles) potential susceptibilities in o�shore areas from certain types of development or activities (e.g. o�shore energy development or longline �shing).

Although it is important to try to avoid and minimize impacts to all birds, e�orts should be made, in particular, to avoid and minimize impacts to the birds on this list, especially eagles and BCC species of rangewide concern. For more information on conservation measures you can implement to help avoid and minimize migratory bird impacts and requirements for eagles, please see the FAQs for these topics.

Details about birds that are potentially a�ected by o�shore projects For additional details about the relative occurrence and abundance of both individual bird species and groups of bird species within your project area o� the Atlantic Coast, please visit the Northeast Ocean Data Portal. The Portal also o�ers data and information about other taxa besides birds that may be helpful to you in your project review. Alternately, you may download the bird model results �les underlying the portal maps through the NOAA NCCOS Integrative Statistical Modeling and Predictive Mapping of Marine Bird Distributions and Abundance on the Atlantic Outer Continental Shelf project webpage.

Bird tracking data can also provide additional details about occurrence and habitat use throughout the year, including migration. Models relying on survey data may not include this information. For additional information on marine bird tracking data, see the Diving Bird Study and the nanotag studies or contact Caleb Spiegel or Pam Loring.

What if I have eagles on my list?
If your project has the potential to disturb or kill eagles, you may need to obtain a permit to avoid violating the Eagle Act should such impacts occur.

Proper Interpretation and Use of Your Migratory Bird Report The migratory bird list generated is not a list of all birds in your project area, only a subset of birds of priority concern. To learn more about how your list is generated, and see options for identifying what other birds may be in your project area, please see the FAQ "What does IPaC use to generate the migratory birds potentially occurring in my speci�ed location". Please be aware this report provides the "probability of presence" of birds within the 10 km grid cell(s) that overlap your project; not your exact project footprint. On the graphs provided, please also look carefully at the survey e�ort (indicated by the black vertical bar) and for the existence of the "no data" indicator (a red horizontal bar). A high survey e�ort is the key component. If the survey e�ort is high, then the probability of presence score can be viewed as more dependable. In contrast, a low survey e�ort bar or no data bar 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 of concern 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 helps you know what to look for to con�rm presence, and helps guide you in knowing when to implement conservation measures to avoid or minimize potential impacts from your project activities, should presence be con�rmed. To learn more about conservation measures, visit the FAQ "Tell me about conservation measures I can implement to avoid or minimize impacts to migratory birds" at the bottom of your migratory bird trust resources page.

Coastal Barrier Resources System
Projects within the John H. Chafee Coastal Barrier Resources System (CBRS) may be subject to the restrictions on federal expenditures and �nancial assistance and the consultation requirements of the Coastal Barrier Resources Act (CBRA) (16 U.S.C. 3501 et seq.). For more information, please contact the local Ecological Services Field O�ce or visit the CBRA Consultations website. The CBRA website provides tools such as a �ow chart to help determine whether consultation is required and a template to facilitate the consultation process.

THERE ARE NO KNOWN COASTAL BARRIERS AT THIS LOCATION.

Data limitations
The CBRS boundaries used in IPaC are representations of the controlling boundaries, which are depicted on the o�cial CBRS maps. The boundaries depicted in this layer are not to be considered authoritative for in/out determinations close to a CBRS boundary (i.e., within the "CBRS Bu�er Zone" that appears as a hatched area on either side of the boundary). For projects that are very close to a CBRS boundary but do not clearly intersect a unit, you may contact the Service for an o�cial determination by following the instructions here: https://www.fws.gov/service/coastal-barrierresources-system-property-documentation Data exclusions
CBRS units extend seaward out to either the 20- or 30-foot bathymetric contour (depending on the location of the unit). The true seaward extent of the units is not shown in the CBRS data, therefore projects in the o�shore areas of units (e.g., dredging, breakwaters, o�shore wind energy or oil and gas projects) may be subject to CBRA even if they do not intersect the CBRS data. For additional information, please contact [email protected].

Facilities
National Wildlife Refuge lands
Any activity proposed on lands managed by the National Wildlife Refuge system must undergo a 'Compatibility Determination' conducted by the Refuge. Please contact the individual Refuges to discuss any questions or concerns.

THERE ARE NO REFUGE LANDS AT THIS LOCATION.

Wetlands in the National Wetlands
Inventory
Impacts to NWI wetlands and other aquatic habitats may be subject to regulation under Section 404 of the Clean Water Act, or other State/Federal statutes.

For more information please contact the Regulatory Program of the local U.S. Army Corps of Engineers District.

WETLAND INFORMATION IS NOT AVAILABLE AT THIS TIME
This can happen when the National Wetlands Inventory (NWI) map service is unavailable, or for very large projects that intersect many wetland areas. Try again, or visit the NWI map to view wetlands at this location.

Data limitations
The Service's objective of mapping wetlands and deepwater habitats is to produce reconnaissance level information on the location, type and size of these resources. The maps are prepared from the analysis of high altitude imagery. Wetlands are identi�ed based on vegetation, visible hydrology and geography.

A margin of error is inherent in the use of imagery; thus, detailed on-the-ground inspection of any particular site may result in revision of the wetland boundaries or classi�cation established through image analysis.

The accuracy of image interpretation depends on the quality of the imagery, the experience of the image analysts, the amount and quality of the collateral data and the amount of ground truth veri�cation work conducted. Metadata should be consulted to determine the date of the source imagery used and any mapping problems.

Wetlands or other mapped features may have changed since the date of the imagery or �eld work.

There may be occasional di�erences in polygon boundaries or classi�cations between the information depicted on the map and the actual conditions on site.

Data exclusions
Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and nearshore coastal waters. Some deepwater reef communities (coral or tuber�cid worm reefs) have also been excluded from the inventory. These habitats, because of their depth, go undetected by aerial imagery.

Data precautions
Federal, state, and local regulatory agencies with jurisdiction over wetlands may de�ne and describe wetlands in a di�erent manner than that used in this inventory. There is no attempt, in either the design or products of this inventory, to de�ne the limits of proprietary jurisdiction of any Federal, state, or local government or to establish the geographical scope of the regulatory programs of government agencies. Persons intending to engage in activities involving modi�cations within or adjacent to wetland areas should seek the advice of appropriate federal, state, or local agencies concerning speci�ed agency regulatory programs and proprietary jurisdictions that may a�ect such activities.
