1 Introduction The Florida Department of Transportation (FDOT) made improvements to the Interstate 95 (I-95) mainline in Palm Beach County in the 1990s and 2000s, adding a High Occupancy Vehicle (HOV) lane and auxiliary lanes from south of Linton Boulevard to north of PGA Boulevard. Minor interchange improvements were also made to eight (8) of the existing 18 interchanges along this section of the corridor. At the time of that project, FDOT committed to re-examining the need for short-term and long-term interchange improvements at the interchanges that were not improved as a part of this previous I-95 mainline project. FDOT District Four also identified the need to reexamine the 2003 I-95 Master Plan Study for Palm Beach County to develop new improvements to interchanges based on changes in traffic volumes and updated design standards since the Master Plan was developed a decade ago. The purpose of this study is to identify short-term and long-term needs through the 2040 design year horizon and develop design concepts to address traffic spillback onto I-95, improve interchange operations, reduce congestion, and increase safety at the 17 study interchanges from Linton Boulevard to Northlake Boulevard. The only interchange within the project limits that is not analyzed in this report is the Palm Beach International Airport (PBIA) direct connection ramps, which do not have signalized ramp terminal intersections. The study also considered Strategic Intermodal System (SIS) connector improvements needed within the project area and is consistent with plans for the I-95 mainline, including the potential extension of I-95 Express lanes through Palm Beach County. This Interchange Master Plan (IMP) report summarizes the evaluations contained within the I-95 Freeway Facility Analysis Report as well as the 17 individual interchange Concept Development Reports (CDRs) produced as part of this study. The location of the overall IMP study area is shown in Figure 1. Master Plan Page 1 December 2015
I-95 (SR 9) Interchange Master Plan Figure 1: I-95 Interchange Master Plan Study Area Master Plan Page 2 December 2015
2 Project Location The overall project area extends approximately 27 miles from just south of Linton Boulevard (Mile Post (MP) 8.1) to just north of Northlake Boulevard (MP 27.1). The study areas for individual interchanges included the interchange ramp terminal intersections and at least one adjacent intersection to the east and west. The interchange Concept Development Reports (CDRs) contain more detailed descriptions of the study area for each interchange. 3 Land Use Plans I-95 crosses through multiple municipalities within the study limits. The land uses adjacent to I-95 varies from municipality to municipality containing uses ranging from residential to commercial or industrial. An excerpt from the Palm Beach County Future Land Use Map is included as Figure 2, depicting the land uses within the study area. The interchange Concept Development Reports (CDRs) contain descriptive details of the existing land uses and land use plans within the project limits at each interchange.

4 Existing (2012/2013) Conditions Existing conditions within the study area for each interchange was collected/gathered from various sources for inclusion in the Concept Development Reports (CDRs). Information collected included roadway and intersection characteristics; bridge, waterway, interchange, or grade separation structures; transit facilities and services; planned and programmed transportation projects; and traffic data. The data was collected/gathered at various times during the project schedule from January 2013 to December 2014 and sources included aerial photography, field visits, FDOT Road Atlas, FDOT Crash Analyses Reporting System (CARS), FDOT Florida Traffic Online, Palm Beach County Engineering Division, Palm Beach County Planning, Zoning, and Building Division, Palm Beach County Metropolitan Planning Organization, School District of Palm Beach County, and Palm Tran. Information was collected from the agency/division websites, coordination with staff, or access to databases. A detailed listing of the collected information is provided below: Roadway and Intersection Characteristics Functional Classifications Typical Sections Lighting Interchange/Ramp Design Intelligent Transportation Systems Utilities Merge and Diverge Areas Posted Speed and Design Speed Pavement Conditions Bicycle and Pedestrian Facilities/Safe Routes to Schools Traffic Signals Emergency Evacuation Routes Intersection Geometry Bridge, Waterway, Interchange, or Grade Separation Structures Typical Section Structures Bridge Inspection/Condition Transit Facilities and Services Transit Services Van-Pool/Car-Pool Activities Park-and-Ride Facilities Connection and Access to Seaport and Airport Planned and Programmed Transportation Projects MPO Plans Long Range Transportation Plan Cost Feasible and Needs Plans Master Comprehensive Bicycle Transportation Plan County and Local Agency Plans and Projects Department Plans and Projects Traffic Data Traffic Counts Field Reviews Master Plan Page 5 December 2015
Crash Data A detailed discussion of each of these topics is included in the Concept Development Reports (CDRs). The following figures summarizing key information have been included in the Appendix: FDOT Functional Classification Maps for Palm Beach County (Appendix A) FDOT Roadway Jurisdiction Maps for Palm Beach County (Appendix B) Florida Division of Emergency Management Evacuation Routes and Zones Maps for Palm Beach County (Appendix C) Palm Tran Bus System Map (Appendix D) Palm Beach Metropolitan Planning Organization (MPO) Long Range Transportation Plan (LRTP) Cost Feasible Plan Map (Appendix E) MPO LRTP Needs Plan Map (Appendix F) MPO Master Comprehensive Bicycle Transportation Plan Needs Map (Appendix G) Existing traffic counts from the Kittelson and Associates, Inc. (Kittelson) I-95 Interchange Master Plan 2012 AADT and Peak Hour Volumes Memorandum, dated March 2013 were utilized for existing conditions analysis. Existing traffic volume figures obtained from the Kittelson Report are included in Appendix H. 5 Design Performance Criteria, Policies, and Procedures As summarized in the I-95 Palm Beach County Interchange Master Plan Methodology Letter of Understanding (MLOU), dated June 2013, analyses of the I-95 system, including the mainline and the interchange ramps, were based on criteria and policies detailed in the FDOT Interchange Handbook, 2002 Edition. A copy of the MLOU is included in Appendix I. Palm Beach County As outlined in the MLOU, factors for analyzing the signalized intersections and arterial segments were consistent with the values provided by the Palm Beach County Traffic Division in the document titled HCM Default Inputs. The Palm Beach County document provides guidance on default values to be utilized in analyses and minimum operational criteria for signalized intersections in Palm Beach County. Input criteria includes traffic factors along with minimums and standards for non-coordinated and coordinated traffic signals. Operational criteria include maximum volume-to-capacity (v/c) ratios and maximum delays. The Palm Beach County Traffic Performance Standards Ordinance (TPSO) specifies Test 1 standards that require that all intersections and roadways satisfy the LOS D threshold using the Highway Capacity Manual Planning Methodology. Palm Beach County TPSO also specifies a Test 2 five-year analysis standard that requires all intersections and roadways to satisfy the LOS E threshold at the end of the fifth year of the Florida Department of Transportation Five-Year Transportation Improvement Program (TIP) in effect at the time of the traffic analysis. The following LOS criteria were utilized for the analyses. Florida Department of Transportation FDOT Topic No. 000-525-006-a provides Level of Service (LOS) standards for the State Highway System (SHS). The SHS automobile LOS Standards during peak travel hours are stated to be LOS D in urbanized areas and C outside urbanized areas. It is the Department s intent to plan, design, and operate the SHS at an acceptable LOS for the travelling public. Master Plan Page 6 December 2015
The I-95 interstate and associated interchange ramps are a designated part of the SIS system and SHS. Therefore, the FDOT LOS D criteria for urbanized areas and LOS C criteria for outside urbanized areas was utilized for the interstate, the ramp terminal intersections, and intersection approaches (i.e. deficient at LOS E or D, respectively). For cross streets that are designated as state roads the LOS D (urbanized) and LOS C (outside urbanized) standards were also utilized for all adjacent intersections and their approaches. For cross streets that are not designated as state roads, the Palm Beach County LOS E standard was utilized for all adjacent intersections and their approaches (i.e. deficient at LOS F). Signalized intersection analyses were conducted utilizing Trafficware s Synchro software package. The HCM2000 reports were utilized for output results. The I-95 mainline analysis was conducted utilizing McTrans Highway Capacity Software (HCS) 2010 Freeway Facilities module. The FDOT Design Standards (Standard Indexes), booklet dated 2014, and FDOT Plans Preparation Manual (PPM), dated 2014, were utilized in the design of the Master Plan improvements. 6 Existing (2012/2013) Operational and Safety Analysis The interchange study intersections within the study limits of each interchange were analyzed during the A.M. and P.M. corridor-wide peak hours (7:30 A.M. 8:30 A.M. and 4:45 P.M. 5:45 P.M.). The detailed analyses are documented in the individual Concept Development Reports (CDRs). In addition, crashes for the years 2010 through 2012 were summarized at each interchange. The existing operations of the I-95 mainline High Occupancy Vehicles (HOV) lane, the four (4) general purpose lanes, and the on- and off-ramps were analyzed during the A.M. and P.M. peak hours. The detailed analysis is documented in the Interstate 95 Master Plan Freeway Facility Analysis (Palm Beach County) Report, dated May 2015. During the A.M. peak hour, at least one of the study intersections currently operates at a deficient LOS at 10 of the 17 interchanges. During the P.M. peak hour, at least one of the study intersections currently operates at a deficient LOS at 10 of the 17 interchanges. Seven of the 17 interchanges have at least one deficient study intersection during both the A.M. and P.M. peak hours. Figures 3A, 3B, and 3C summarize the existing LOS at each of the study intersections during the A.M. peak hour. Figures 4A, 4B, and 4C summarize the existing LOS at each of the study intersections during the P.M. peak hour. For I-95 mainline, 7 northbound freeway segments and 4 southbound freeway segments are anticipated to operate at a deficient LOS E during either the A.M. or P.M. peak hour. Figure 5 summarizes the critical existing LOS along the I-95 mainline during the A.M. and P.M. peak hours (i.e. worse LOS in either the A.M. or P.M. peak hour). Master Plan Page 7 December 2015

7 Traffic Forecasting The enhanced SERPM version 6.5, Managed Lanes model, (base year model 2005 and future year model 2035) developed as part of the I-95 Project Development and Environmental (PD&E) Study (Stirling Road to Linton Boulevard), was used for the Palm Beach County Interchange Master Plan (IMP). This model uses adopted 2035 cost feasible networks which were enhanced with I-95 subarea-specific improvements for this I-95 IMP and MPO-developed socio-economic data. The design year 2040 scenario was developed by extrapolating the MPO-developed TAZ data to 2040 conditions. Bureau of Economic and Business Research (BEBR) 2040 estimates were used to benchmark the 2040 extrapolated TAZ data. 7.1 Land Use Changes A review of the SERPM employment and population data revealed the trends for changes in the future land use in the project area. Figures depicting the 2005 and 2035 population and employment data are included in Appendix J. Each interchange Concept Development Report (CDR) includes a description of the observations for population and employment growth within the vicinity of the interchange. 7.2 Analysis Years and Model Runs The following are the analysis years for this I-95 IMP. Base/Validation Year: 2010 Opening Year: 2020 Design Year: 2040 7.3 2020 and 2040 Directional Design Hour Volume (DDHV) The 2040 base model produced the 2040 A.M. peak period, P.M. peak period, and off-peak volumes for the ramps, arterials, and I-95 mainline. These A.M. and P.M. peak period volumes represent 3-hour peak periods; the model s off-peak consists of an 18-hour period. The A.M. and P.M. 3-hour peak period volumes were converted to A.M. and P.M. directional design hour volumes (DDHVs) using factors of 0.395 and 0.365, respectively. These DDHV factors were calculated for the I-95 corridor utilizing data obtained from 24-hour counts along I-95. First, the total volume for the peak three hour periods was calculated (6:30 9:30 A.M. and 3:30 6:30 P.M.). Next, the total volume for the peak one-hour within the peak three-hour period was calculated. The DDHV factor was then calculated by dividing the peak one-hour period volume by the peak three-hour period volume (see below). DDHV Factor = Peak one hour count within three hour peak (i.e. 7:30 8:30 A.M.) Peak three hour count (i.e. 6:30 9:30 A.M.) The 2020 DDHVs were interpolated between the 2040 DDHV and the existing 2012/2013 traffic counts. Master Plan Page 15 December 2015
A calibration effort using Cube Analyst produced satisfactory model validation results. The reasonableness checks indicated consistent growth across the corridor. Post-processing adjustments were performed to adjust volumes for ramps with negative growth. Future Year Turning Movement Forecasts The 2040 travel demand model was refined to produce turning movement forecasts for the intersections within the study limits. These turning movement forecasts were extracted from the model to an excel spreadsheet for processing. The processing step was conducted to adjust the forecasts as follows. The estimated turning movements were reviewed to ensure the forecasts were not less than the existing volumes. If the 2040 forecasts were lower than the existing volumes, adjustments were performed using a growth rate method. An annual growth rate of 0.89 percent was applied to the existing volume to estimate the 2040 volumes. This growth rate is the weighted annual growth rate estimated from the overall Palm Beach County population and employment growth. Manual adjustments were applied to movements to balance the network of intersections. The forecasts were reviewed to ensure each leg of the study intersections presented logical growth. A combination of manual adjustment for balancing and the growth rate method was applied to develop the refined forecasts. Figures summarizing the balanced 2020 and 2040 forecasted volumes along I-95 as well as the turning movements for each of the study interchanges and adjacent intersections are included in Appendix K and Appendix L, respectively. 8 Opening Year (2020) No Build Conditions Traffic Operational Analysis Traffic operational and queuing analyses were conducted to evaluate the short-term 2020 No-Build conditions (without roadway improvements) for all study interchanges. Traffic signal timing has been optimized which reflects routine maintenance operations. It has been assumed that the traffic signal timing would be optimized to accommodate changes in approach demand due to future traffic growth and the optimization would be practical to implement. The traffic signal optimization was only assumed for the intersections within the AOI and implementation of optimized signal timings was not analyzed for adjacent intersections within the control section but outside the AOI. Additionally, committed improvements by FDOT and/or Palm Beach County anticipated to be by 2020 were also included as part of the No-Build Conditions. The following committed improvement were included in the analysis: Gateway Boulevard I-95 southbound ramp southbound approach: restripe two (2) left-turn lanes and one (1) right-turn lane as one (1) left-turn lane and two (2) right-turn lanes. I-95 southbound ramp eastbound approach: restripe four (4) through lanes and one (1) right-turn lane as three (3) through lanes, one (1) shared through/right-turn lane, and one (1) right-turn lane. Master Plan Page 16 December 2015
Woolbright Road I-95 southbound ramp westbound approach: one (1) additional left-turn lane. I-95 northbound ramp eastbound approach: one (1) additional left-turn lane. Incorporation of the optimized signal timing and programmed improvements resulted in certain intersections having a lower delay (i.e. better LOS) in the 2020 No-Build conditions than for the existing conditions. The purpose of the 2020 No-Build analysis was to identify anticipated short-term deficiencies and needs at the study intersections that could be addressed prior to the implementation of the longterm improvements identified for the 2040 Design Year. Utilizing the results of these intersection operational and queuing analyses, recommended roadway improvements could then be developed to address the short-term needs at the interchanges and adjacent signalized intersections. A.M. and P.M. peak hour operational analyses were performed for the study intersections to estimate 2020 delay and LOS utilizing Synchro. The Synchro results are included in the Appendices of each individual Concept Development Report (CDR). During the A.M. peak hour, at least one of the study intersections is anticipated to operate at a deficient LOS at seven of the 17 interchanges. During the P.M. peak hour, at least one of the study intersections is anticipated to operate at a deficient LOS at seven of the 17 interchanges. Three of the 17 interchanges have at least one deficient study intersection during both the A.M. and P.M. peak hours. Due to the signal timing optimization and committed improvements several of the interchange intersection operations were improved from the existing conditions. Figures 6A, 6B, and 6C summarize the 2020 No-Build LOS at each of the study intersections during the A.M. peak hour. Figures 7A, 7B, and 7C summarize the 2020 No-Build LOS at each of the study intersections during the P.M. peak hour. I-95 mainline was analyzed utilizing HCS. The HCS results are included in the Appendix of the Interstate 95 Master Plan Freeway Facility Analysis (Palm Beach County) Report, dated September 2015. For I-95 mainline, 8 northbound freeway segments and 10 southbound freeway segments are anticipated to operate at a deficient LOS E or F during either the A.M. or P.M. peak hour. Figure 8 summarizes the critical 2020 No-Build LOS along the I-95 mainline during the A.M. and P.M. peak hours (i.e. worse LOS in either the A.M. or P.M. peak hour). Master Plan Page 17 December 2015

9 Opening Year (2020) Build Conditions Traffic Operational Analysis (With Improvements) Based on the results of the 2020 No-Build analyses short-term, interim, improvements were developed for the 2020 opening year. Peak hour (A.M. and P.M.) operational analyses were performed for the study intersections to estimate 2020 delay and LOS after implementation of the improvements utilizing Synchro. The Synchro results are included in the Appendices of each individual Concept Development Report (CDR). Tables summarizing the changes in delay anticipated in 2020 with the implementation of the recommended improvements at each of the 17 interchanges during the A.M. and P.M. peak hours is included in Appendix M. With the recommended improvements, all study intersections are anticipated to operate at an acceptable LOS, except Boynton Beach Boulevard at Seacrest Boulevard. Improvements were developed for this intersection; however, significant right-of-way acquisition would be necessary for construction and was determined not to be feasible. It should be noted that although the intersection will operate at a deficient LOS, the operations will not impact the I-95 interchange ramps. A list of the recommended improvements for each interchange is included below. The Interchange Concept Development Reports (CDRs) provide a detailed description of the recommended improvements and the associated roadway design considerations.

Figures 9A, 9B, and 9C summarize the 2020 Build LOS at each of the study intersections during the A.M. peak hour. Figures 10A, 10B, and 10C summarize the 2020 Build LOS at each of the study intersections during the P.M. peak hour. A list of the recommended improvements along I-95 mainline at each interchange is included below. I-95 mainline was analyzed utilizing HCS. The HCS results are included in the Appendix of the Interstate 95 Master Plan Freeway Facility Analysis (Palm Beach County) Report, dated September 2015. Okeechobee Boulevard Interchange Extend two-lane southbound on-ramp to 1,500 feet prior to merging into the single lane ramp/auxiliary lane. 45 th Street Interchange The two-lane southbound on-ramp should be extended to 1,500 feet prior to merging into the outside lane of I-95. For I-95 mainline with improvements, 8 northbound freeway segments and 10 southbound freeway segments are anticipated to operate at a deficient LOS E of F during either the A.M. or P.M. peak hour. Figure 11 summarizes the critical 2020 Build LOS along the I-95 mainline during the A.M. and P.M. peak hours (i.e. worse LOS in either the A.M. or P.M. peak hour). It should be noted that the Build mainline LOS results in Figure 11 are the same as the No-Build mainline LOS results in Figure 8. An improvement in LOS upon implementation of the ramps improvements was not recognized along the mainline because HCS calculates LOS based on density for the mainline and while the improvements will benefit traffic utilizing the ramps, the number of mainline lanes and vehicles in those lanes (i.e. density along the mainline) remained effectively unchanged.

10 Design Year (2040) No Build Conditions Traffic Operational Analysis Traffic operational and queuing analyses were conducted to evaluate the long-term 2040 No-Build conditions (without roadway improvements) for all study interchanges. Traffic signal timing has been optimized which reflects routine maintenance operations. It has been assumed that the traffic signal timing would be optimized to accommodate changes in approach demand due to future traffic growth and the optimization would be practical to implement. The traffic signal optimization was only assumed for the intersections within the AOI and implementation of optimized signal timings was not analyzed for adjacent intersections within the control section but outside the AOI. Additionally, committed improvements by FDOT and/or Palm Beach County anticipated to be by 2040 were also included as part of the No-Build Conditions. The following committed improvement were included in the analysis: Gateway Boulevard I-95 southbound ramp southbound approach: restripe two (2) left-turn lanes and one (1) right-turn lane as one (1) left-turn lane and two (2) right-turn lanes. I-95 southbound ramp eastbound approach: restripe four (4) through lanes and one (1) right-turn lane as three (3) through lanes, one (1) shared through/right-turn lane, and one (1) right-turn lane. Woolbright Road I-95 southbound ramp westbound approach: one (1) additional left-turn lane. I-95 northbound ramp eastbound approach: one (1) additional left-turn lane. Incorporation of the optimized signal timing and programmed improvements resulted in certain intersections having a lower delay (i.e. better LOS) in the 2040 No-Build conditions than for the existing conditions. The purpose of the 2040 No-Build analysis was to identify anticipated long-term deficiencies and needs at the study intersections. Utilizing the results of these intersection operational analyses and queuing analyses, recommended roadway improvements and corresponding Conceptual Design Alternatives (CDAs) could then be developed to address the long-term travel demand at the interchange and adjacent signalized intersections. Peak hour (A.M. and P.M.) operational analyses were performed for the study intersections to estimate 2040 delay and LOS utilizing Synchro. The 2040 forecasted volumes are presented in Appendix C. The Synchro results are included in the Appendices of each individual Concept Development Report (CDR). During the A.M. peak hour, at least one of the study intersections is anticipated to operate at a deficient LOS at 16 of the 17 interchanges. During the P.M. peak hour, at least one of the study intersections is anticipated to operate at a deficient LOS at 14 of the 17 interchanges. Fourteen of the 17 interchanges have at least one deficient study intersection during both the A.M. and P.M. peak hours. Figures 12A, 12B, and 12C summarize the 2040 No-Build Master Plan Page 37 December 2015
LOS at each of the study intersections during the A.M. peak hour. Figures 13A, 13B, and 13C summarize the 2040 No-Build LOS at each of the study intersections during the P.M. peak hour. I-95 mainline was analyzed utilizing HCS. The HCS results are included in the Appendix of the Interstate 95 Master Plan Freeway Facility Analysis (Palm Beach County) Report, dated September 2015. For I-95 mainline, 12 northbound freeway segments and 12 southbound freeway segments are anticipated to operate at a deficient LOS E or F during either the A.M. or P.M. peak hour. Figure 14 summarizes the critical 2040 No-Build LOS along the I-95 mainline during the A.M. and P.M. peak hours (i.e. worse LOS in either the A.M. or P.M. peak hour).

11 Conceptual Design Alternative Evaluation Conceptual design alternatives (CDAs) were developed for each interchange and evaluated to determine the most viable alternative that considers practical design and the optimum Benefit-to- Cost (B/C) ratio without compromising overall traffic operations and safety. CDAs were evaluated for horizontal geometry, typical section, constructability and impacts on structures, drainage, signing, utilities, adjoining side street connections and signalized intersections, as well as opportunities for the integration of multimodal systems, utilization of ITS applications, and consideration for prioritization for SIS connectors. The interchange CDAs along with their typical sections are included in the appendices of the individual reports. 12 Summary of 2040 Build Improvements 12.1 I-95 at Northlake Boulevard The following improvements are recommended, impacting all five study intersections: Widen I-95 northbound off-ramp left-turn movement to provide triple (3) left-turn lanes. Widen I-95 northbound on-ramp to accommodate free-flow westbound to northbound right-turn. Widen I-95 southbound off-ramp to provide quadruple (4) left-turn lanes. Add a second westbound left-turn lane at the Northlake Boulevard and Keating Drive intersection. Build retention pond to account for additional impervious area.

One community resource, an undeveloped parcel partially owned by the Covenant Centre International (church), is anticipated to be impact by a recommended stormwater pond. The areas in the vicinity of the interchange are not considered minority or low income communities. The proposed improvements will require additional right-of-way along the north and south sides of Northlake Boulevard both east and west of the I-95, as well as the west side of Sunrise Drive north of Northlake Boulevard. This acquisition of right-of-way has the potential to impact approximately 39 commercial businesses. Four (4) gas stations are anticipated to be impacted by the improvements. These four gas stations have documented discharges within the FDEP State Storage Tank and Petroleum Contamination Monitoring (STCM) program that have ongoing cleanup activities. Master Plan Page 47 December 2015
The C-17 Canal and stormwater ponds are located near the proposed improvements, but will not be impacted. However, an unnamed canal connecting to the SFWMD C-17 Canal has the potential to be impacted by the proposed improvements. Impacts to threatened or endangered species or their habitats are not anticipated. The cost for the improvements is estimated to be approximately $10.3 million including maintenance of traffic, mobilization, and contingency costs, but does not include right-of-way acquisition costs. The estimated Benefit-to-Cost (B/C) ratio is 9.8 and Net Present Value (NPV) is approximately $55.0 million. The recommended next steps are an Interchange Modification Report (IMR) and a Project Development and Environment (PD&E) Study. This project is considered a Major Project as the costs are anticipated to exceed $20 million, including right-of-way acquisition costs. 12.2 I-95 at Blue Heron Boulevard The following improvements are recommended, impacting all four study intersections: Extend eastbound left-turn lane at the 42nd Way intersection. Add a third southbound left-turn lane to the I-95 southbound off-ramp. Extend the eastbound auxiliary lanes at the I-95 southbound ramps. Add a third northbound left-turn lane to the I-95 northbound off-ramp. Extend the westbound auxiliary lanes at the I-95 northbound ramps. Extend eastbound left-turn lane at the Garden Road intersection. Add northbound right-turn lane at the Garden Road intersection. Extend southbound right-turn lane at the Garden Road intersection.

Right-of-way acquisition is not anticipated; however, coordination with the South Florida Water Management District (SFWMD) will be required to obtain a right-of-way occupancy permit for the proposed improvement at the southeast corner of the Garden Road intersection. No relocation impacts are anticipated. Seventeen (17) potential petroleum contamination sites were identified within the vicinity of the interchange; however, only two of these sites are located near the proposed improvements. No impacts to wetlands or surface waters are anticipated. Impacts to threatened or endangered species or their habitats are not anticipated. The cost for the improvements is estimated to be $2.1 million, including maintenance of traffic, mobilization, contingency, and design-build costs, but does not include right-of-way acquisition costs. The estimated B/C ratio is 19.4 and NPV is approximately $17.5 million. The recommended next steps are a Non-Interstate Access Report (Non-IAR) and a Programmatic Categorical Exclusion (PCE) Checklist. This project is considered a Minor Project as the costs are anticipated to be less than $8 million, including right-of-way acquisition costs. 12.3 I-95 at 45 th Street The following improvements are recommended, impacting all six study intersections: Add a fourth through lane in each direction of 45th Street from just west of Village Boulevard to east of Congress Avenue. Add additional two left-turn lanes and a right-turn lane on I-95 southbound off-ramp to provide quadruple (4) left-turn lanes and triple (3) right-turn lanes. Add additional two left-turn lanes and a right-turn lane on I-95 northbound off-ramp to provide quadruple (4) left-turn lanes and triple (3) right-turn lanes. Add a dedicated northbound through lane on Village Boulevard and convert shared lane to dedicated left-turn lane. Add a second (dual) southbound right-turn lane on Village Boulevard. Master Plan Page 49 December 2015
Add a dedicated southbound right-turn lane on Northpoint Boulevard. Figure 17 depicts the existing and proposed laneage configuration.

Civil rights and environmental justice considerations will need to be accounted for in the recommended Project Development and Environmental (PD&E) study due to a majority of minority households and large percentage of family incomes below poverty level. The proposed improvements will require additional right-of-way along the north and south sides of 45 th Street both east and west of I-95, the east side of Village Boulevard south of 45 th Street, the west side of Village Boulevard north of 45 th Street, and the west side of Northpoint Parkway/Metrocentre Boulevard north of 45 th Street. Acquisition of new right-of-way has the potential to impact 26 properties; however, none of these properties are anticipated to require relocation. Master Plan Page 50 December 2015
One (1) of the impacted properties is a gas station in the STCM program. The FDEP contamination locator map indicates that there is active petroleum cleanup for this site. The improvements will require the widening of the SFWMD C-17 Canal which may result in temporary impacts to the Canal. Impacts to wood stork foraging habitat are the only threatened or endangered species impacts anticipated. The cost for the improvements is estimated to be approximately $42.2 million including construction, maintenance of traffic, and mobilization, but does not include right-of-way acquisition costs. The estimated B/C ratio is 3.6 and NPV is approximately $25.4 million. The recommended next steps are an Interchange Modification Report (IMR) and a Project Development and Environmental (PD&E) Study. This project is considered a Major Project as the costs are anticipated to exceed $20 million, including right-of-way acquisition costs. 12.4 I-95 at Palm Beach Lakes Boulevard The following improvements are recommended, impacting all five study intersections: Add a fourth eastbound through/right lane on Palm Beach Lakes Boulevard to be extended from Robbins Drive until I-95 southbound. Add a fourth through lane on Palm Beach Lakes Boulevard between I-95 southbound ramps and Robbins Drive.

Environmental Justice considerations will need to be accounted for in subsequent phases due to the large percentage of minority households. The proposed improvements will require additional right-of-way along the north and south sides of Okeechobee Boulevard, both east and west of the I-95 interchange. The right-of-way acquisition has the potential to impact 11 commercial properties; however, none of the aforementioned businesses are anticipated to require relocation. Of the 11 commercial properties potentially impacted, one (1) is a gas station. Based on the FDEP contamination locator map and associated OCULUS database files, this gas station has potential contamination risks. The canals and stormwater ponds near the proposed improvements will not be impacted. However, Clear Lake has the potential to be impacted by the proposed construction of a multiuse path that has a segment running along the southern shoreline of the lake. Impacts to threatened or endangered species or their habitats are not anticipated. The cost of improvements is estimated to be approximately $8.9 million including construction, maintenance of traffic, mobilization, and contingency costs, but does not include right-of-way acquisition costs. The estimated B/C ratio is 3.9 and NPV is approximately $10.5 million. The recommended next steps are a Non-Interstate Access Report (Non-IAR) and a Programmatic Categorical Exclusion (PCE) Checklist. This project is considered a Medium Project as the costs are anticipated to be between $8 million and $20 million, including right-of-way acquisition costs. Master Plan Page 54 December 2015
12.6 I-95 at Belvedere Road The following improvements are recommended, impacting all five study intersections: Add a fourth through lane in each direction of Australian Avenue extending from 600 feet north of Australian Avenue to James L. Turnage Boulevard. Add a fourth through lane in each direction of Belvedere Road from just west of Australian Avenue to west of I-95 southbound. Add a third southbound and westbound left-turn lane to the intersection of Belvedere Road and Australian Avenue. Add a second eastbound left-turn lane to Belvedere Road at Parker Avenue. Add a second northbound through lane on Parker Avenue north of Belvedere Road. Extend I-95 southbound off-ramp auxiliary lane. Add a second right-turn lane to I-95 northbound off-ramp. Add an auxiliary lane on I-95 southbound on-ramp to accommodate free flow movement from eastbound Belvedere Road. Figure 20 depicts the existing and proposed laneage configuration.

One State Historic Preservation Officer (SHPO) Structure in the vicinity of the improvements has been evaluated by SHPO and was determined to be ineligible for NRHP listing. The bridge over the West Palm Beach Stub Canal is proposed to be widened, but this canal may be considered a resource protected under Section 4(f) of the Department of Transportation Act. Coordination with the Federal Highway Administration would be required to determine if the resource is protected under Section 4(f). No other SHPO Resource Group, SHPO Structure, or community resources are anticipated to be impacted. Civil Rights and Environmental Justice considerations will need to be accounted for in subsequent phases of Project Development and Environmental (PD&E) due to the large percentage of minority households and families with incomes below the poverty level. The proposed improvements will require additional right-of-way along the north and south sides of Belvedere Road west of I-95, the north side of Belvedere Road at Parker Avenue, the east side of Parker Avenue north of Belvedere Road, the east side of Australian Avenue south of Belvedere Road, and the west side of Australian Avenue north of Belvedere Road. Acquisition of new rightof-way has the potential to impact 48 properties and it is anticipated that at least 14 of these properties are likely to require relocation. The recommended improvements are anticipated to impact four (4) gas stations. The FDEP OCULUS database indicates that petroleum cleanup is pending at one (1) gas station and is active at the other three (3) gas stations. Widening of the bridge over the Stub Canal will result in impacts to the canal and the construction of the northbound thru lane on Australian Ave may impact one (1) stormwater pond northeast of the intersection with Belvedere Road. No other impacts to wetlands or surface waters are anticipated. Relocation permits for gopher tortoises and nest removal permits for burrowing owls may be required. Potential foraging habitat for wood storks is marginal; thus no impacts are anticipated. Impacts to other threatened or endangered species are not anticipated. The cost for improvements is estimated to be approximately $12.1 million including construction, maintenance of traffic, and mobilization, but does not include right-of-way acquisition costs. The estimated B/C ratio is 2.8 and NPV is approximately $5.5 million. The recommended next steps are an Interchange Modification Report (IMR) and a Project Development and Environmental (PD&E) Study. This project is considered a Major Project as the costs are anticipated to exceed $20 million, including right-of-way acquisition costs. Master Plan Page 56 December 2015
12.7 I-95 at Southern Boulevard The following improvements are recommended, impacting three of the four study intersections: Add an eastbound-to-northbound single lane flyover ramp to access I-95 northbound onramp. Add a westbound-to-southbound single lane flyover ramp to access I-95 southbound onramp. Realign I-95 northbound off-ramp approach to Southern Boulevard and provide quadruple (4) left-turn lanes and dual (2) right-turn lanes. Widen I-95 southbound off-ramp southbound right-turn movement to provide triple (3) right-turn lanes. Widen I-95 southbound on-ramp eastbound-to-southbound right-turn movement to dual (2) right-turn lanes. Widen Southern Boulevard to provide dual (2) left-turn lanes both eastbound and westbound at Parker Avenue. Add a second northbound left-turn lane at the Southern Boulevard and Parker Avenue intersection. Provide southbound dedicated right-turn lane on Parker Avenue at Southern Boulevard intersection. Replace/modify all affected existing overhead sign structures. Construct all affected sidewalk crossings per ADA standards. Figure 21 depicts the existing and proposed laneage configuration.

Environmental Justice considerations will need to be accounted for in a future Project Development and Environmental (PD&E) because the surrounding census tracts are comprised of primarily minority communities. Minor right-of-way acquisition impacts are anticipated on the south side of Southern Boulevard west of the interchange and on the north side of Southern Boulevard to the east of the interchange. Relocation impacts are not anticipated. No direct impacts to hazardous waste or contaminated sites are anticipated. The SFWMD Stub Canal would be impacted by the proposed improvements, which include widening the crossing over the canal. No other impacts to wetlands or surface waters are anticipated. Impacts to threatened or endangered species or their habitats are not anticipated. The cost of improvements is estimated to be approximately $57.5 million including construction, maintenance of traffic, and mobilization, but does not include right-of-way acquisition costs.

Blue Heron Boulevard Interchange Extend northbound on-ramp lanes to provide two lanes for 1,500 feet past the gore point with I-95 prior to merging to a single lane. Extend southbound on-ramp lanes to provide two lanes for 1,500 feet past the gore point with I-95 prior to merging to a single lane. This improvement will require additional pavement, retaining wall, and two cantilever signs. No additional right-of-way acquisition is anticipated. The total cost for improvement is estimated to be approximately $2.2 million.

13 Design Year (2040) Build Conditions Traffic Operational Analysis (With Improvements) Based on the results of the 2040 No-Build analyses long-term improvements were developed for the 2040 design year. Peak hour (A.M. and P.M.) operational analyses were performed for the study intersections to estimate 2040 delay and LOS after implementation of the improvements utilizing Synchro. The Synchro results are included in the Appendices of each individual Concept Development Report (CDR). Tables summarizing the change in delay anticipated in 2040 with the implementation of the recommended improvements at each of the 17 interchanges during the A.M. and P.M. peak hours is included in Appendix O. With the recommended improvements, all study intersections are anticipated to operate at an acceptable LOS, except for 45 th Street at Congress Avenue, Okeechobee Boulevard at Congress Avenue, Boynton Beach Boulevard at Seacrest Boulevard, and Atlantic Avenue at Congress Avenue. Improvements were developed to allow these intersections to operate at an acceptable LOS; however, significant right-of-way acquisition would be necessary for construction and was determined not to be feasible. It should be noted that although the intersections will operate at a deficient LOS, the operations will not impact the I-95 interchange ramps. Figures 32A, 32B, and 32C summarize the 2040 Build LOS at each of the study intersections during the A.M. peak hour. Figures 33A, 33B, and 33C summarize the 2040 Build LOS at each of the study intersections during the P.M. peak hour. I-95 mainline was analyzed utilizing Highway Capacity Software (HCS). The HCS results are included in the Appendix of the Interstate 95 Master Plan Freeway Facility Analysis (Palm Beach County) Report, dated September 2015. For I-95 mainline, 10 northbound segments and 15 southbound segments are anticipated to operate at a deficient LOS E or F during either the A.M. or P.M. peak hour. Figure 34 summarizes the critical 2040 Build LOS along I-95 mainline during the A.M. and P.M. peak hours (i.e. worse LOS in either A.M. or P.M. peak hour shown). It should be noted that the Build mainline LOS results in Figure 34 are the same as the No-Build mainline LOS results in Figure 14 for all segments except Gateway Boulevard to Hypoluxo Road and Hypoluxo Road to Gateway Boulevard in the northbound and southbound directions, respectively. An improvement in LOS upon implementation of the ramps improvements was not recognized for most segments along the mainline because HCS calculates LOS based on density for the mainline and while the improvements will benefit traffic utilizing the ramps, the number of mainline lanes and vehicles in those lanes (i.e. density along the mainline) remained effectively unchanged. It is important to note that the purpose of the Interchange Master Plan was to identify interchange improvements. Subsequent studies of I-95 mainline will be needed to identify improvements to address the anticipated I-95 mainline delays and LOS. Master Plan Page 79 December 2015

14 Findings As summarized in the report, it has been determined that improvements are needed at 16 of the 17 study interchanges by 2020 (all interchanges except Forest Hill Boulevard) and improvements are needed at all 17 interchanges by 2040. The recommended improvements at each interchange can be categorized in three (3) separate groups: 2020 recommended improvements, 2040 recommended improvements, and Optional Non-Critical Arterial Improvements. Please note that Optional Non-Critical Arterial Improvements were identified, but determined not to be necessary or critical to the operations of the interchange; therefore, are considered optional/to be considered for funding by other local agencies. Each interchange Concept Development Report (CDR) has an in depth discussion of the implementation strategy for the recommended improvements. Table 1 provides a summary of the construction cost, B/C, and NPV for each of the interchanges based on the 2040 recommended improvements.

Utilizing the construction costs summarized above and through coordination with FDOT regarding initial right-of-way costs/assumptions, the interchange projects were categorized into Major, Medium, and Minor projects. The improvement projects were considered to be Major if the total costs were anticipated to exceed $20 million, Medium if the total costs were anticipated to be less than $20 million, but greater than $8 million, and Minor if the total costs were anticipated to be less than $8 million. Figure 35 depicts the project category for each of the interchanges. Figure 35: Major, Medium, and Minor Project Summary Master Plan Page 88 December 2015
