HIALEAH -- '4, . - INTERNATIONAL 'AVEOrY CORAL ! f.ARI FS - KEY BISCAYNE STATEPAIR 5 m1 D 6 MIAMI 1-395 UNDERDECK Situated north of Downtown Miami, the project is within or adjacent to multiple established and emerging neighborhoods: Overtown, Omni, Downtown, and the Innovation District. The Underdeck TAT, PAH is a new 33 -acre open space that is slated to transform a formerly infrastructural corridor near Miami's urban core into a significant landscape and actively programmed destination for residents, - workers, and visitors. The entire 1-395 project will be built by the Florida Department of Transportation ("FDOT"). The City of Miami will operate and maintain the open space and therefore has an important voice in every MIAMI4 stage of the project. The Concept Plan presented here builds on the significant work that the City, -., BEACH owl. `-Tr FDOT, and others have completed over the past several years to create a broad vision and practical roadmap for integrating the City's goals, from community development to fiscal prudence, into the ,VIRGINIA KEY larger project's plan and execution.

Overtown sustained the most significant damage to its physical structure and urban vitality and was separated further from Miami's other downtown neighborhoods by the FEC Railway. This potential for the Underdeck to transform 1-395 from a feature that divides the City and neighborhoods to one that unifies them has been fully embraced by the FDOT and Joint Venture (JV) Team. The Underdeck is an expansive and intentionally pedestrian -oriented open space, achieved by Increasing bridge clearances (from as little as +/- 25' in the east to as much as +50' in the west), and by reducing the number of columns (from +/-800 to +/-200). As the future operator of the Underdeck, the City of Miami has committed to designing and implementing a governance structure that provides responsible, sustainable stewardship of the open space in perpetuity in line with three key City objectives, which will also underpin the business plan and programming strategy for long-term open space operations: MIAMI 1-395 UNDERDECK 0 CREATE A SIGNATURE OPEN SPACE The Underdeck will be a place with strong identity and a cohesive design. • Distinctive design elements will generate excitement • Innovative and evolving programming will draw return visitation • Best -in -class design and a well-defined identity will create a space that reinforces Miami as one of the world's most distinctive cities 0 STRENGTHEN COMMUNITIES The Underdeck will strengthen adjacent communities, their assets, and their future. • By creating a common public realm and providing open space for use by all, the Underdeck will become a place of gathering for people of all ages; a diversity of neighbors; and regional, national and international visitors to Miami. • Green infrastructure forms the backbone of the design, to ensure a legacy open space t that will allow varied and evolving programming — from passive to active. • In maintenance, operations and programming, the park has the opportunity to support the development of the local workforce and to be an incubator for small businesses. • Revenue -generating opportunities onsite will support both nearby communities and Underdeck operations. 0 DRIVE ECONOMIC VITALITY The Underdeck will create value, a critical element in the success of this project. • Create anew and memorable gateway to downtown • Harmonize and engage with adjacent development • Increase property values and tax increment to drive a critical funding source for long- term operations and maintenance 0 WELCOME ALL USERS The Underdeck will be a place that feels safe and welcoming to all users. Public realm that is vibrant, attractive, programmed and heavily used is the best deterrent to undesirable use that detracts from the beneficial impacts of the Underdeck. • Attracting a diversity of users and making a place that is inclusive will drive the success of the project. The design of the open space supports this goal in many ways: ample and beautiful lighting, appropriate material selection, features that will attract a variety of users and use, and infrastructure needed for maintenance and operations. • CPTED (Crime Prevention Through Environmental Design) principals have been incorporated throughout planning and design of physical improvements and anticipated use of the Underdeck. MIAMI 1-395 UNDERDECK 9 INTRODUCTION This Basis of Design document is a high-level visual and narrative description of City of Miami's ex- BASIS x- BASIS OF DESIGN pectations for the 1-395 Underdeck, to be designed and constructed in close collaboration with Flori- da Department of Transportation (FDOT) and the Archer -Western -de Moya Joint Venture (JVTeam). The contents of this document represent the goals and objectives of the City of Miami, FDOT, adja- cent stakeholders, communities and civic leaders, as interpreted by the design team at the time of issue. This document sets forth the baseline criteria for the desired program, aesthetics, functional- ity, performance and compliance of the project, given the diverse and complex drivers and pressures on the project. The Basis of Design document is a development of the vision established in the JVTeam's'Heritage Trail Aesthetic Master Plan and Manuals: The planning and design reflected in this document has been deeply informed by FDOT's prior planning and design work, including significant neighbor- hood -level community engagement. Additional stakeholder, community, City and County input, as well as on-going coordination with FDOT has significantly guided the creation of this document. As a "living document", the Basis of Design is anticipated to evolve through revision and addenda, in order to ensure the communication of project intent through design, construction, commissioning, and the initial operations & maintenance phases of the Underdeck. The City believes that a robust governance strategy is essential to the phased development and long-term operational sustainability of the Underdeck. Indeed, a high-quality design as proposed in this Basis of Design document, will require experienced, accountable, and dynamic leadership to deliver and maintain. Over the next several months, this project team will work with the City and its cross -sector partners who are committed to the success of the Underdeck to develop a governance strategy and business plan for the open space that enables the City to operate the Underdeck effi- ciently and responsibly, and which ensures that the open space's neighbors and Miamians of all ages can enjoy the Underdeck for generations to come. A summary of the City's progress and next steps regarding the development of these plans can be found in the Appendix.

The Underdeck is a public landscape designed to promote the equitable environmental, social, and economic vitality of Miami, while also forming a resilient and flexible framework for evolving program needs, creating a shared public resource, while also supporting on- site revenue generation. This project is a precedent -setting reclamation of marginalized and underused infrastructural space for much-needed public green open space and recreation. Dense understory and broad canopy plantings are maximized, while hardscapes are minimized, in order to achieve a welcoming counterbalance to adjacent development and the highway above. The Underdeck is a surprising and revelatory respite, woven beneath and between FDOT and Miami's bustling transportation system. The Underdeck is a landscape framework, which integrates multiple distinct character zones across the mile -long open space, responding to its diverse urban context through a range of flexible and evolving programming: COMMUNITY GREEN I The western -most node is defined by community green space, interspersed with play opportunities for all ages and abilities, and small-scale food and beverage facilities. ACTIVE HEART I Both sides of the FEC rail crossing are activated with recreational uses for children and adults, supporting connectivity across the rail tracks. LIVE WORK PLAY I Further east near Omni, the open space provides larger hardscaped and lawn areas for temporary events and festivals, as well as urban gardens for respite. CIVIC WATERFRONT I The eastern end of the Underdeck serves as a civic front yard and bridge to Miami's arts and culture destinations. HERITAGE TRAIL I Connecting these spaces, the continuous east -west promenade flows seamlessly through the length of the project, bridging over the FEC rail.

The following proposed regulations primarily govern two areas, short-term uses and defining a framework for future long-term changes to the site -plan. Land -use regulations governing the FDOT owned space and City leased space below and adjacent to 1-395 are based on the Miami 21 Code and are organized according to that document structure. Numbering of articles, figures, and tables conforms to Miami 21. (Two sections of italicized text show subjects which remain to be resolved). ARTICLE 1. DEFINITIONS 1.1. DEFINITIONS OF USES 1.1.1. Unless otherwise stated, definitions of terms from Miami 21 Article 1 shall apply. 1.1.2. CIVIC EMERGENCY SHELTER: Short-term facilities erected related to an emergency which may provide all uses required for sustained comfort including, for example, sleeping accommodations, dining, bathing, recreation, education, administrative space, and all activities required of a self-contained facility.

ARTICLE 3. GENERAL TO ZONES 3.4 DENSITY AND INTENSITY CALCULATIONS 3.4.1 Lot Area, inclusive of any dedications, is used for purposes of Density and Intensity calculation. Italicized text is for reference to understand the implications of and need to establish a clear framework for subsequent regulations. (City of Miami intent is to either create zoning which applies to the parcel boundary or create a mechanism in the Lease agreement which effectively creates zoning regulations. A. Zoning as shown in typical Right of Way (R.O. W.) a. Zoning regulations do not typically apply to areas of ROW b. Adjacent zoning is typically shown in maps since adjacent owners regain area upon vacation of ROW and current zoning on the private property would then apply to reclaimed land. B. Buildings and business crucial for operation and maintenance typically require: Platted land=> Parcels => Folio => Physical Address => Certificate of Occupancy => Business Tax Receipt, C. Folio creation method is to be determined and options include: a. Defining boundary line as parcel and applying regulations through lease. b. Replat to create a parcel c. Create a lease arrangement to supplant folio requirement. D. Future steps (to be completed prior to next agreement) a. Precisely define the boundaries of the project with a survey containing metes and bounds. b. Determine method to create folios or suitable facsimile for building and business permitting through options above.) ARTICLE 4.

Each'strand'is horticulturally distinct, composed of planting palettes that draw on both native species and habitats, while also integrating culturally significant species from the Caribbean, Central and South America. Each'strand'is characterized by specific requirements for sun exposure and water. The strands and species within each strand are organized in response to sun & shade conditions created by the 1-395 bridges, existing and anticipated future development. The planting of the Underdeck will be a robust living framework, essential to the success of this significant addition to Miami's public open space infrastructure. Sufficient landscape soils in volume and quality are expected, in order to ensure successful establishment and growth over time. Irrigation is anticipated for all planting areas; plant communities are designed to accommodate efficient irrigation zoning. 42 MIAMI 1-395 UNDERDECK PLANTING - UNDERSTORY H o - SCHOOL BOARD GIBSON PARK LAWN PLANTING Eleventh St® ADRIENNE ARSHT I�p/`� MUSEUM PARK MAURICE A.

The proposed storm water management system for the project as presented in the report"100% Final Draft Drainage Report 1-395 Reconstruction" dated August 2019, consist on the collection of the deck runoff by Non -Standard scuppers and conveyed by vertical downspouts (8"-12"diam) located on the interior of the bridge piers. The flow is then intercepted by AVS (22) for water quality and ultimately discharge on gravity wells (34). Due to the low-grade elevation east of NE 2nd Avenue and high groundwater elevations, a pump station will be required to discharge runoff into the Biscayne Aquifer via three (3) deep injection wells. The collection of runoffs on the Underdeck and surrounding areas will be addressed by existing infrastructure and connections to the new gravity well system. The revised storm water concept review mainly focuses on the Underdeck in order to incorporate the revised concept Design developed by the city of Miami Team, maintaining as much as possible the proposed design. DESIGN OBJECTIVES The revised Stormwater Management Conceptual Design for the Underdeck objective is to incorporate The City of Miami design and philosophies with minimal changes into the proposed design, including green stormwater infrastructure systems. 62 MIAMI 1-395 UNDERDECK INTERACT Pass Through Potable WATER - STORM N O' r� t J ; m ; W ; Z ; Q PRECIPITATE N Dry/ Wet Seasons m Hurricanes CAPTURE EVAPOTRANSPIRE Green Roofs Tree Canopy Vertical Biofiltration INTERACT Above -Grade Cisterns Re -Circulating Potable .......

Additional Guidance on Green Infrastructure: • Regional Impacts of Climate Change and Issues for Stormwater Management • Low -Impact Development & Green Infrastructure: Pollution Reduction Guidance for Water Quality in Southeast Florida. BOUNDARY CONDITIONS The groundwater parameter will remain as per project documents. • For the purpose of water quality, a groundwater elevation of 1.0 NAVD will be accepted. • For all other drainage calculations, a variable tailwater will be required for the groundwater elevation. The elevation varies from 1.0 NAVD to 2.0 NAVD at the peak of the storm event modeled. • Safety Factor of 1.5 is required for well capacity calculations. Ground elevation varies throughout the project from approximated 2 ft to 12 ft. Moving highest to lowest from west to east respectively. STORMWATER GREEN INFRASTRUCTURE The incorporation and diversification of Stormwater Management Strategies addresses the City of Miami and the regions efforts to use public spaces to develop green stormwater infrastructure to re- duce runoff, improve water quality, and educate the public. Both Miami Dade County and the City of Miami governments have developed strategies to address the current and projected future climate changes and build a resilient and sustainable future. (Table x). The revision to the Underdeck concept design consist on the incorporation of green infrastructure wherever feasible on the open space. The effectiveness of most proposed green stormwater Man- agement Systems depends on the depth of the groundwater table. Therefore, as a standard practice the seasonal high groundwater table must be at least two feet beneath the bottom of any filtration system, unless an alternative design can be demonstrated as being more appropriate for the specific site conditions based on plans, test results, calculations, or other documented information. HARVESTING /TREATMENT/INFILTRATION Proposed Stormwater management Green infrastructure: Rain Harvesting System and Irrigation System Stormwater will be intercepted after it passes through the AVS an directed to an underground tank. Capacity of proposed rain harvesting water and Irrigation system will be determine based on the irrigation needs of the final design landscape plan. The system must include: • Underground tanks must be groundwater stable. must be designed to resist buoyant forces from high water tables. • Rainwater harvesting system must include pre-treatment component. • Rainwater harvesting system must include Rainwater Pump Stations for distribution. • Irrigation Distribution System must be connected to both storage and Water Service. MIAMI 1-395 UNDERDECK Access must be provided for inspection and cleaning, but humans or animals must be prevented from entering the cistern. o Very large cisterns may need to have an OSHA Confined Entry permit and meet other safety criteria. Pervious Pavements Permeable pavers, gravel paths and other pervious material must be used on walkways whenever possible and according to the design ascetics. Full infiltration design is recommended for this proj- ect. Adherence to design guidelines for pavement design and base courses will ensure structural stability. Bioretention Systems A variety of bioretention measures should be implemented on the project stormwater system, utilizing vegetated areas as stormwater management and reducing the size of the stormwater system. This system will be combined with proposed with overflows connected to current system. Bioretention facilities should beset back at least 15 ft from building foundations. Design standards on roadway drainage should be consulted. It may be necessary to provide a barrier to keep water from saturating the road's sub -base. Types of bioretention included as proposed measures are: Vegetated Swales Vegetated Swales provide conveyance while slowing, infiltrate, and filter stormwater flows. Over- flow shall be connected to the storm water system. Swales should not be constructed within 75 feet of a public or private potable water supply well or within 15 feet of an onsite wastewater dis- posal and treatment system. Swales are not appropriate on sites with potential hazardous or toxic materials. MIAMI 1-395 UNDERDECK Curb extensions and tree pits Part of the Green Street concept, curb extensions and tree pits are proposed on the areas adjacent to roads where street parking is proposed or sidewalks close to the road. They are usually are located within the road right of way and take advantage of the landscaped space between the sidewalk and street. They can be designed to take runoff from the sidewalk or street. They are typically designed to be offline, that is when they are full the stormwater will bypass the practice and flow to the down- stream street inlet. Stormwater Planter Planters Infiltration planters are small scale variation of bioretention areas, Stormwater planters are recom- mended throughout the project area, as of many configurations are possible. Stormwater planters located near building foundations will need to have an impermeable liner under the bioretention media or the foundation will need to be waterproofed. 1 In the case of drainage wells and AVS, provide the injection well chamber with physical access devices or maintenance activities. Maintenance of the injection well includes cleaning, removing debris, and, NW 15TH STREET in some cases, redeveloping the well to re-establish discharge capacity. The well location needs to be • accessible from the surface to allow these activities to take place.

The water and sewer infrastructure have been analyzed based on MIAMI 1-395 UNDERDECK size, material and age of the piping systems to identify potential system deficiencies and potential required improvements to bring the system up to code as part of the project. Below is a description of each. POTABLE WATER The purpose of this section is to identify the potential points of connection to the MDWASD water distribution system in the project area, as well as to analyze the distribution system for possible deficiencies and identify water main extension requirements that may be needed to provide adequate service to the proposed facilities included in the Underdeck Conceptual Plan. Required improvements shall conform with the MDWASD Donation Standard Specifications and Details for Design and Construction. EXISTING SYSTEM The project is in the urban downtown core where water distribution systems are available throughout the site. The existing system has been analyzed for size, material and age in order to establish viable potential new points of connection to service the Underdeck. Within the project limits, existing water lines range from 2 inches to 24 inches, and most are either ductile iron or cast- iron piping. A significant portion of the water distribution system in the area is over 50 years old, with some newer pipes on the eastern side of the project area. The Underdeck project is located in the water central sub -basin, and will be served by the Hialeah -Preston Water Treatment Plants, which have a permitted capacity of 225 million gallons per day (MGD) and an annual average flow of 131.3 MGD. MIAMI 1-395 UNDERDECK DEMAND ESTIMATION Potable water demand has been estimated based on Exhibit B of the MDWASD manual, Schedule of Daily Rated Gallonage for Various Occupancy, for both the Underdeck water uses and the Emergency Response site demand. The following is a list of the demand assumed for concept development: COMMERCIAL LAND USES • Restaurant (Full Service) —100 gpd/100 sq. ft. • Food Preparation Outlet— 35 gpd/100 sq. ft INDUSTRIAL LAND USES • Public Park with toilets and showers — 20 gpd/person (assume 2,000 per day) OTHER • Water Features—TBD • Splash Pad — 50 gpm Since landscape irrigation does not include sewer collection, landscape irrigation is not included in the water demand calculations for MDWASD reservation application. A separate irrigation line will be proposed with an irrigation meter, and water used for irrigation will be billed as it is used. Demands for the Emergency Response Site will require further discussions with MDWASD, as these demands are atypical and do not require constant flow, but rather would be used only in the event of activation of the Emergency Response Site. These demands will likely fall under a category not currently shown in Exhibit B indicated above, and will therefore require special consideration. POINTS OF CONNECTION AND REQUIRED IMPROVEMENTS MAINTENANCE REQUIREMENTS AND RESPONSIBILITIES The main service to the Underdeck will be provided by tapping new connections to the MDWASD All water mains installed for the purposes of water distribution, within FDOT right-of-way and within system in the vicinity. These locations have been identified based on estimated order -of -magnitude Underdeck project limits, will be conveyed to MDWASD after installation and will thereafter be demand needed for specified service points and the nearest feasible connection to a watermain, operated and maintained by MDWASD. Service connections will require easements up to the water considering its size, age, and material. Ultimate points of connection will require further coordination meter. Anything beyond the water meter is the responsibility of the City of Miami. with MDWASD. On the east side of the project [east of the Florida East Coast (FEC) railroad track] existing watermain sizes would allow for new service connections. On the west side, some watermains may have to be upsized from the existing 6 -in diameters to 12 -in lines to allow service connections to distribute to proposed service points. Based on the new demand and the existing infrastructure available, the following infrastructure SANITARY SEWER The purpose of this section is to identify the potential points of connection to the MDWASD sanitary sewer collection system in the project area, as well as to analyze the sanitary sewer system for possible deficiencies and identify sewer main extension requirements that may be needed to provide adequate service to the proposed facilities included in the Underdeck Conceptual Plan. Required improvements shall conform with the MDWASD Donation Standard Specifications and improvements may be required: Details for Design and Construction. • A 12 -inch water main extension along NW 1st Place between NW 11 Terrace and NW 17 Street EXISTING SYSTEM • A 12 -inch water main extension along the west end of NW 1 st Avenue between NW 11 Terrace The project is in the urban downtown core where sanitary sewer distribution systems are available and NW 13 Street • A 12 -inch water main extension along NW 11 Terrace between NW 2nd Avenue and NW 1st Avenue throughout the site. The existing system has been inspected forage, material, and size in order to establish viable potential new points of connection to service the Underdeck. Within the project limits, existing sewer lines range from 8 inches to 10 inches, and most are either vitrified clay or unknown material. The system in the area appears to be at least 50 years old. The project is located in the central service area, and is served by the Central District Wastewater Treatment Plant, which currently has a permitted capacity of 143 MGD and an average influent flow of 110.20 MGD. MIAMI 1-395 UNDERDECK PUMP STATION CAPACITIES N EXT STEPS The entire Underdeck project falls within the County's pump station No. 002 boundary. The Due to the extensive development in the urban core of the County, it is recommended the City operating status of this pump station, which is typically measured by the Nominal Average Pump of Miami apply for a letter of availability to MDWASD in order to secure flow from the water and Operating Time (NAPOT), is currently set as OK, with an operating time of 6.47 hrs. Therefore, this sewer systems. This process will require preliminary demand calculations for the project, and once pump station shows adequate capacity for the projected flows from the proposed project. approved will allow for the City to move into final design without concerns that the systems will POINTS OF CONNECTION AND REQUIRED IMPROVEMENTS not have adequate capacity. In addition, once a final conceptual design is approved by the City and FDOT for the Underdeck project, it is recommended to submit for a Water & Sewer Developer's The main service to the Underdeck will be provided by making new connections to the Miami -Dade Agreement with MDWASD, as this will determine the actual points of connection and identify any WASD system in the vicinity. These locations have been identified based on estimated order -of- additional water and sewer main extensions not identified to date. magnitude demand needed for specified service points and the nearest feasible connection to an existing sewer line, considering its size, age, and material. Ultimate points of connection will require further coordination with MDWASD. In addition, since concession buildings are being added under the 1-395 bridge and assuming existing gravity sewers in the area are shallow, small private grinder pumps are being proposed. MAINTENANCE REQUIREMENTS AND RESPONSIBILITIES Sanitary Sewer collection mains will be conveyed after construction and will be operated and maintained by MDWASD. Lateral connections extending from the property line and inside the property are to be maintained by the City of Miami. A cleanout will be installed at the property line to separate the two lines.

FERRE PARK SANITARY SEWER EAST MIAMI 1-395 UNDERDECK UTILITIES POWER The project provides new electrical connections to the proposed Underdeck open space facilities and infrastructure. The project will provide power for concessions, restrooms, play and active rec- reation areas, event/stage areas, plazas, irrigation systems, water features, lighting on the pedes- trian bridge, and supplemental aesthetic lighting on abutment walls, art installations, and general aesthetic lighting. Additionally, the project assumes to provide GFCI receptacles at light poles, wi-fi capabilities, security, and future charging stations for electric vehicles. The Underdeck also allows sufficient capacity for establishment of a 500-1000 person base camp during emergencies. DESIGN OBJECTIVES Estimate additional power demand for the Underdeck open space programming, features, and ame- nities; and identify locations for new load centers. CODES, STANDARDS, AND REFERENCES Florida Power and Light (FPL) Electric Service Standards and per the project RFP. References for load estimation • National Fire Protection Agency (NFPA) NFPA-70-2020 • FDOT Standards • Federal Highway Administration (FHWA) Lighting Handbook August 2012 • Illuminating Engineering Society of North America (IESNA) ANSI/IES RP -8-18 Recommended Prac- tice for Design and Maintenance of Roadway and Parking Facility Lighting 9 MIAMI -395 UNDERDECK INFRASTRUCTURE & DESIGN ELEMENTS Initial assumptions FDOT, FPL, and the JV team have identified load centers A through G to service the infrastructure systems on 1-395 roadways and structures over the Underdeck open space. Also included in the 1-395 loads is the lighting embedded in the structures soffit to provide illumination to the Under - deck surface below. Since there is no spare capacity in the 1-395 load centers, additional ones are required to distribute power to the proposed amenities and programming in the Underdeck. Demand Estimation and Distribution The electrical load to support the Underdeck programming and infrastructure has been estimated at approximately 2,750 kVA, via five (5) new load centers. These are distributed in two main elec- trical zones divided by the Florida East Coast (FEC) Railway, Electrical Zones 1 and 2. This approach allows for separate utility services that eliminate any encroachment into the FEC right of way, and evenly distributes loads throughout the area. One load center is provided in each zone to service most of the Underdeck demand, and addition- al load centers are provided to service'event'areas. Event areas are assumed to be flexible spaces for programming, which can become power intensive and should be isolated from the remainder of the site. For Electrical Zone 1 west of the FEC Railway, a 750kVA, 480/277V, three (3) phase, four (4) wire ser- vice at NW 2nd Ave is proposed to minimize conductor sizes for the community plaza area, where flexible programming is expected (Le. food trucks, farmer's market, community events). Electrical MIAMI 1-395 UNDERDECK Zone 1 also features a separate 500 kVA, 480/277V, three (3) phase, four (4) wire service near the in- tersection of NW 14th Street and NW 2nd Court to support Event 1 site. For Electrical Zone 2 encompassing the portion east of the FEC railway, a 315kVA, 480/277V, three (3) phase, four (4) wire service at NE 1 st Ave is proposed for the bulk of the Underdeck open space loads. A separate 500kVA, 480/277V, three (3) phase, four (4) wire services at NE Miami Court and near the intersection of NW 13th Street and NE 1 st Court are proposed to support the Event 2 and Event 3 sites, respectively. The estimated power capacity provided for the Underdeck would also allow for the establishment of a temporary base camp at the designated areas for emergency response in the site. Performance and Specifications Power load center estimates are based on equipment kVA. It is assumed that FPL will only provide services at one voltage, 480 V. Thus, transformers are needed to accommodate voltage level require- ments and voltage drop based on specific needs. Load center locations have been established outside of bridge envelopes to eliminate potential overhead clearance restrictions. Locations consider maintenance accessibility from public right-of- way. The space assumed at each location is based on clearance requirements provided in the FPL Electric Service Standards Figure V-1: three (3) feet of clearance to non -access faces and eight (8) feet to collocated equipment or where access is needed. Each site would feature a hedge enclosure, with an eight (8) foot wide access break. A typical location is approximately fourteen (14) feet wide by ten (10) feet deep.

FERRF PARK ELEVENTH ST J LJ I Oo' ioo zoo' aoo ON -STREET PARKING ANALYSIS The team assessed the availability of existing on -street parking to understand how much supply exists in the areas adjacent to the Underdeck. A partial on -street parking inventory was obtained from the Miami Parking Authority (MPA). Where MPA data was not available, the study team used aerial images and Google Street View data to estimate the length of on -street parking on each block. The study team sought to account for no parking zones, driveways, fire hydrants, loading and taxi zones, and no -parking zones. However, the values presented in this analysis should be considered estimates, since individual parking spots are not striped in the study area. Having measured the estimated length of available on -street parking, the study team then esti- mated the number of available parking spaces. Miami -Dade County's Code of Ordinances (Article VII, Section 33-122) sets 23 feet as the minimum length for a legal parallel parking spot. Thus, the total length of legal on -street parking on the block was divided by 23 to determine the number of spaces. Area of Analysis: This analysis is based on an estimated of on -street parking located between NW 15th Street and NW 3rd Avenue to the northwest, NW 11 th Street and NW 3rd Avenue to the southwest, Biscayne Boulevard and NE 15th Street to the northeast, and Biscayne Boulevard and SE 11 th Street to the southeast. DESIGN OBJECTIVES CURRENT DESIGN VS. PROPOSED DESIGN The City's proposed design seeks to minimize parking in the Underdeck space, instead relying to the fullest extent possible on the existing supply of on -street parking. From the on -street parking per- spective, no significant departures are proposed from the Joint Venture team's current design, with some exceptions. The City's proposal provides more detail and context than the existing JV concepts. Second, the City's design proposal identifies specific pick-up and drop-off zones for Transportation Network Companies (TNC). Itwill also identify, through further refinement, locations for bus loading and unloading. Subsequent refinements will call for micro -mobility parking and hubs, where appro- priate. The goal, is to minimize to the extent possible the number of passenger vehicle trips made to the Underdeck space. This will be accomplished through the strong transit linkages (Miami Trolley, Metromover, DTPW bus routes), TNCs, micro mobility technologies, and an activated, and bicycle and pedestrian -friendly environment that encourages walking and cycling. Summary of Conditions More than 1,180 on -street parking spaces are located within the areas adjacent to the underdeck. Parking is more prevalent west of the FEC corridor, where this analysis counted over 600 spaces. The east side of the corridor has approximately 560 spaces. Some of this parking will be removed once the 1-395 rebuild is complete. For instance, parking on NE 13th Street, which is anticipated to serve as access to the 395 on -ramps will likely result in a reduction or elimination of on -street parking on this street. This assumption is supported by typical sections obtained from FDOT. LOCATION ESTIMATED NUMBER OF ON -STREET SPACES The City's team is seeking to balance the needs for a successful Underdeck open space with the need for vehicular accessibility and parking convenience. Both elements are important compo- East of FEC 560 nents for the project's success. Providing excessive parking in the Underdeck space has the poten- West of FEC 624 tial to compromise the functionality of the open area, limiting FDOT and the City's'opportunities TOTAL: 1,184 for maximizing utility in the space. To minimize the number of parking spaces provided in the Underdeck, the study team quantified the availability of on -street parking.

(Note that this analysis only accounts for the on -street parking within the limits described above. Thus, it does not consider parking east of Biscayne Boulevard, or north of NE 15th Street, or south of NE 11 th Street.). The walksheds were created using straight-line 1/4 and 1/2 mile buffers. Studies typically show that a quarter -mile is a comfortable walking distance. Additionally, the study team assessed parking within a 1/2 mile buffer. This distance was evaluated because walksheds can be increased when safe, well -lit, and engaging pedestrian environments are provided. The Underdeck project, once completed, will be a welcoming pedestrian environment that will encourage longer walking distances. Thus, when estimating the amount of on -street parking within walking distance of the Arsht Center, counts for both walksheds are presented. DISTANCE FROM ARSHT NUMBER OF ON -STREET PARKING SPACES AVAILABLE '/4 mile 251 1/2 mile 816 The team estimated approximately 250 on -street parking spaces within the 1/4 mile walkshed, which is approximately 20 percent of the study area's total parking. Over 810 parking spaces exist within the half -mile walkshed, which accounts for nearly 70 percent of the study area's total. PARKING SPACES PERSON -TRIP ASSUMPTION THEATERGOERS % PATRONS (ZIFF CAPACITY 2,400) 816 1.4 1,100 45% 2.0 1,600 66% The City of Miami assumes a person -trip rate of 1.4 passengers per vehicle. Thus, the 816 parking spaces available within the 1/2 mile buffer could accommodate over 1,100 theatergoers (45% of the Opera House's capacity). A person -trip of over 2 per vehicle is probable for the theater, which could equate to over 1,600 patrons (66% of the Opera House's capacity). Note that this analysis is of on -street parking spaces within the Underdeck study area and excludes surface lots and garages. Moreover, it does not account for on -street parking to the north and east of the Performing Arts Center. As such the on -street capacity within the study area should not be expected to accommodate 100% of the performing arts center's demand. With the assumptions delineated here, it is the conclusion of this analysis that the on -street parking available in the study area is sufficient to meet the demands of the Arsht Center, in coordination with use of the multi -use plazas between Biscayne Boulevard and NE 1 st Avenue for valet during events. Valet circulation on the block between Biscayne Boulevard and NE 2nd Avenue will be accomodated on the plaza, separated from pedestrians by bollards and trees. The Arsht Center has seen significant changes in how their patrons are commuting to performances;TNCs now account for 15% of the modal split, and that percentage is only expected to row. Additionally, other measures should be implemented to enhance multimodal access to the facilities. Coordination between the City, County and Arsht Center could extend DTPW and Miami Trolley operating hours, thereby accommodating later performances. Other transportation modes, such as the Free Bee shuttles, should also be considered as part of the general mobility strategies. Finally, the Arsht, in coordination with the OMNI CRA and surrounding property owners, should institute a central parking garage strategy. This final recommendation would shift the burden of parking demands from existing public facilities and vacant surface lots (that are becoming increasingly scarce as development continues to expand), and provide another parking resource to the Arsht.

They will provide sound attenuation for the traffic above and nearby, and create delight for all ages. At Biscayne Blvd, beneath the signature bridge and in the civic heart of the open space, the water feature will be of a scale that will serve as a gateway feature to the Underdeck. The fountain will emphasize the opening between the bridge structures above by catching the sunlight that will stream through, and will create adjacent veils of water and light, seemingly falling from the bridge structure above - emphasizing the height and drama of the bridge. West of the FEC Rail, an interactive water feature will animate the plaza formed by the pedes- trian bridge landing. The waterjets will both fall from the bridge structure above as it curves "pFE around the plaza and will erupt from the plaza surface next to the ramp in a random pattern rte- thatwill be animated for maximum play and surprise effect. The third water feature will be a splash pad integrated with the children's play area to the -1 west of NW 3rd Ave, facilitating play by smaller kids and relief from the heat for all. 1 l SME. oE I'EI`XE IEI E UIF LQ MAURICE A.

X DETAIL ANALYSIS . . . . . . . . . . . . . . . . . . . . . . X COMPARISON JV PLAN & CITY PLAN Both the JV Plan and the City Plan demonstrate a commitment to delivering a quality public open space to the citizens of Miami, achieving FDOT's guiding objectives for the 1-395 Resconstruction/ Enhancements: (1) Reconnecting Communities and (2) Revitalizing Overtown. The JV Plan for the Underdeck identifies four key design objectives: Community, Safety, Mobility, and Sustainability. The'I-395 Miami Heritage Trail Aesthetic Master Plan, identifies the following benefits / advantages / added value of the design: 1. Heritage Trail, providing connectivity between Overtown and Biscayne Boulevard, bonds together the communities across This diverse urban landscape. 2. Bold landscape design underneath the entire i-395 viaduct commensurate with transformative nature of 1-395 reconstruction. 3. Extensive bridge underdeck lighting system for the Heritage Trail and all open spaces below 1-395 (turning night into day) for maximum nighttime use and safe community conditions. 4. The resulting under bridge areas serves to attract people for a variety of activities and entertainment, becoming a focal point for the community 5. Accommodation for future mixed use building sites including water and power stub -outs, allowing the municipal and civic stakeholders to further plan out the long-term future of the area. 6. Illuminated crosswalks and LED signage to improve safety for pedestrians and bicycles. Based on the City of Miami's intent to operate and maintain the Underdeck, the City Plan presents a modification to the JV Plan, aligning the physical improvements with anticipated governance, programming, operations & maintenance strategies. The broad approach to landscape systems (paving, planting, furniture / lighting) and programmatic features are consistent with the JV Plan, as outlined in the following detailed analysis. In particular, the Clty Plan recognizes and builds from the JV Plan's inspirational vision for a 'Miami Heritage Trail'- a civic promenade linking NW 3rd Avenue in Overtown to Biscayne Boulevard, and celebrating the diverse historic and contemporary cultural richness of Miami. 124 MIAMI 1-395 UNDERDECK MIAMI 1-395 UNDERDECK LEGACY WALL MIAMI 1-395 UNDERDECK 125 JV PLAN / CITY PLAN COMPARISON 0 EMBRACE'MIAMI HERITAGE TRAIL' CONCEPT Build on the JV Plan concept of a'Miami Heritage Trail', linking neighborhoods from Biscayne Bay to Overtown and celebrating Miami's historic and contemporary culture through integrated public art, feature lighting, and open space enhancements.

MEMORANDUM To: Florida Department of Transportation (FDOT) From: HR&A Advisors, on behalf of Design and Planning Team for City of Miami Date: Tuesday, March 31, 2020 Re: Miami 1-395 Underdeck Governance and Business Plan [DRAFT — FDOT REVIEW] INTRODUCTION HR&A Advisors, as part of the City of Miami's consultant team, is working to develop a governance strategy and business operational framework for the 1-395 Underdeck. Enclosed, please find HR&A's presentation to FDOT on February 20, 2020. This presentation, delivered in person in Miami, walks through governance considerations and potential models that the City is weighing as it seeks to create a framework through which it and its partners can operate the Underdeck open space in a manner that is both fiscally sustainable in the long-term and that ensures the public purpose and use of the space in perpetuity. Also enclosed is an earlier progress report on potential funding streams for the open space delivered on September 10, 2019. This brief memorandum serves as a progress update to FDOT on the work of the City team to date and its plan to deliver a proposed operational structure by September 2020. GOVERNANCE STRATEGY The long-term success of an open space is wholly dependent on the strength of its governance strategy. A sound governance strategy is rooted in a clear vision for the open space and is supported by one or more entities with clear operational and oversight responsibilities, working in concert with one another to ensure that: (1) the open space's business model is funding its operations in a manner that is consistent with the needs of the space and its vision, and (2) the management of the space is accountable to its users and other stakeholders. For the Underdeck, HR&A has been advising the City team — in tandem with the design process led by Hargreaves Jones and WSP — on the range of governance models that have been developed to manage high-quality signature open spaces in other major cities. Each of these models is responsive to, and built upon, a unique local political, economic, and physical context, and no single existing model will translate directly to Miami and the Underdeck. However, The City of Miami's goal of maintaining public purpose while leveraging creative funding sources is a driving force for the most successful open space operators around the world. To date, the City has reviewed precedents from across the United States, Canada, and the United Kingdom to assess how the Underdeck can leverage capital investment, create a diversified funding strategy, ensure robust programming, and establish long-term stewardship, with a particular focus on three key precedents: Chicago's Millennium Park, as well as Brooklyn Bridge Park and the High Line in New York City. In an effort to secure wide support for a new Underdeck open space, and to ensure that its design and operations meet the needs of the people of Miami, the City has created an Advisory Body with representatives from major cultural institutions, community organizations, local philanthropic partners, and other neighbors of the future Underdeck. The City team has held design and brainstorming sessions with the Advisory Body as a whole and its subcommittees in-person and virtually on several occasions over the last few months, including to discuss the potential for subcontracting operational elements, questions of land New York I Dallas I Los Angeles I Raleigh I Washington DC ownership, opportunities for value capture, and strategies for ensuring that the entity is accountable to the public. In the most recent governance -focused conversation with the Advisory Board, a session on February 21 5t that covered the same information and models contained in the attached presentation delivered the day prior to FDOT, the group discussed: (1) the need for a new governing entity to be independent from, but accountable to, the City as well as local stakeholders and users; (2) the need for funds collected via value capture mechanisms to be fully and transparently dedicated to Underdeck operations; and, (3) a desire to evaluate other local models, including the operator agreement for the Adrienne Arsht Center for the Performing Arts (Arsht Center) adjacent to the future Underdeck, as potential templates for a governance structure for the open space. The Advisory Body is most interested in implementing a model in which various entities with unique responsibilities work together to manage and operate the space: A partnership between a new Conservancy that focuses most of its energy on fundraising and advocating for the Underdeck, and a "Friends of" group that leads day-to-day operations. This model is most similar to Brooklyn Bridge Park in New York and the Arsht Center, and is also similar to the emerging governance structure for Miami's own Underline. Between April and September 2020, the City and consultant team will continue to engage the Advisory Body for input on key questions related to the development of the Underdeck's future governance model, with a common understanding of the parameters under which such structure will operate, including the terms of the City's lease agreement with the State of Florida for the land on which the open space will sit. Crucially, the City and consultant team will also continue to engage other local government stakeholders, including: (1) the City Attorney, and representatives of the City's Department of Real Estate and Asset Management to understand the legal feasibility of the different governance models; (2) City Commissioners, whose buy -in is fundamental to the success of the open space; and, (3) representatives of the area's Community Redevelopment Agencies (CRAB). The City team has also begun to engage local foundations such as the Knight Foundation and the Miami Foundation and others, to create a programming vision for the Underdeck that ensures vibrant, sustainable activation of the space in the long term. BUSINESS PLAN A sustainable business plan goes hand-in-hand with an open space's governance strategy in ensuring the health of the space in perpetuity. While we understand that capital funds have been allocated to the construction of the Underdeck, an essential step towards the delivery of the space, this team's experience developing business plans for open spaces across the country suggests that ongoing revenues will be much harder to procure than these one-time capital funds. For this reason, over the next five months, the City and its consultant team will be developing an advanced estimate of ongoing operations and maintenance costs based on the Hargreaves Jones design presented in this document. We will estimate ongoing revenues from a variety of sources that could fill an expected operational gap. Revenue sources that will be considered as part of this analysis include: • Value capture: Open spaces like the Underdeck create immense value for cities and neighborhoods, and this value can often be quantified in the form of increased adjacent property values and pace of new development, new visitors and tourism, and increased retail spending. Local jurisdictions frequently use Business Improvement Districts (BIDS), Park Improvement Districts (PIDs), Special Assessment Districts (SADs), and Tax Increment Financing (TIF) to capture this value locally and leverage it to pay for the cost of the open space investment and/or its operations. • Earned income: Revenues collected from programming and activation of open space play a key role in revenue diversification strategies for open spaces, as is evidenced by the case study examples in the attached presentations. Open space operators and administrators can use this highly flexible revenue source to build the space's brand and strengthen operating revenue. This revenue source is fully determined and dependent on the design of the open space, as programming opportunities rely on specific physical features and spaces. Specific earned income sources include: temporary retail (e.g., markets, demountable kiosks), permanent on-site retail (including the HR&A Advisors, Inc. 1-395 Underdeck Progress Upu o,� i�,VCi.16fice Strategy and Business Plan 1 2 proposed restaurant at the southwest corner of Biscayne Blvd. and NE 13'h Street), events (e.g, concerts, recreational programming), venue rentals (e.g., for weddings, corporate events), digital advertising, equipment rental, and parking. Note: each of these potential strategies will be evaluated on the basis of feasibility and alignment with an overarching vision for the open space that emphasizes public purpose and use. Contributed income: Donations from various open space stakeholders and users, typically raised on an annual basis and requiring trained staff to source and manage. Sources can include: direct philanthropic contributions, memberships (annual support for space operations in exchange for merchandise, advance notice of events, ticket discounts, etc.), and sponsorship (most often used as a source of capital funding, but can also be paired with events to offset operational costs). Public funding: Open spaces typically require a base of public funding, particularly in early years of operation as other revenue streams stabilize. Recognizing the City's mission to deliver a revenue - neutral open space, the consultant team will prioritize the above three sources before considering direct City funding through general fund expenses and/or a dedicated tax stream. The consultant team's business planning work between April and September 2020 will focus on developing detailed revenue projections for a stabilized year of operations for the Underdeck. These revenue projections, as well as the underlying operating cost projections will be dependent on the space's design. As such, the HR&A team will closely evaluate the concept design as reviewed by FDOT to estimate costs driven by design features and revenues that can be generated by, among other sources, design -dependent earned income. Based on our understanding of the local open space context in Miami and the proposed concept design for the Underdeck, we believe that revenues will be evenly fairly distributed between three primary streams: (1) value capture and limited direct public funding, (2) earned income from events and on-site concessions, and (3) contributed income, including a mix of sponsorship, philanthropic donations, and giving. The consultant team's experience with high-quality signature open spaces nationwide that are comparable to the Underdeck suggests that the City can anticipate that annual operations and maintenance costs will fall within a range of $200,000 to $350,000 per acre, or between $6.6 and $11.5 million total per year. By comparison, Chicago's Millennium Park (25 acres) has an annual operating cost of $5.5M, Discovery Green in Houston (1 2 acres) annual O&M totals $4.2M, and nearby Bayfront Park, of a similar size to the future Underdeck, has a $6.2M operating budget, spending $194,000 per acre. The Underdeck's high per -acre operating cost relative to these spaces is a function of: (1) the concentration of high-quality design features that require specialized care to maintain, including several water features, designed landscapes, and a signature pedestrian bridge, (2) anticipated heavy programming across the space that will be necessary to keep the Underdeck an active, vibrant place, and (3) the anticipated wear -and -tear on the space resulting from high traffic on its surfaces (e.g., by valeted vehicles) and surrounding roadways (including 1-395 above). Over the next few months, we will further validate these figures to ensure that the final business plan is based on the most relevant precedents, adjusted for the local context.

VISION -LED • The Underdeck needs to be highly programmed to create a critical mass of activity, which requires a focused, experienced, and empowered management entity. BUSINESS -MINDED • The governing entity must be entrepreneurial, creating revenue generating opportunities onsite and becoming a destination that attracts philanthropy and other contributed income (sponsorships, memberships, naming rights, etc.). FLEXIBLE • The governing structure of the Underdeck should be dynamic, allowing for shifting responsibilities and evolving core capacities over time, which may draw on expertise from multiple entities. COLLABORATIVE • The governing entity needs to be responsive to multiple stakeholders — FDOT, the City, and major funders — balancing needs through legal agreements, leases, and governing control.

Alba, PE, PTOE SUBJECT: Underdeck Roadway Closures Analysis DATE: April 1, 2020 INTRODUCTION The purpose of this memorandum is to assess the traffic impact of the closure of the following roadway segments as proposed in the concept plan for the I-395 Underdeck project. • NW 13'h Street between NW Ist Court and NW 1St Avenue • NW 1st Court between NW 13th Street and just south of NW 14th Street The I-395 Underdeck project is a new 33 -acre public open space, located beneath Interstate Highway 395, extending from NW 3rd Avenue and Gibson Park in the west to Biscayne Boulevard, Museum Park and Biscayne Bay in the east. Situated north of Downtown Miami, the project is within or adjacent to multiple established and emerging neighborhoods: Overtown, Omni, Downtown, and the Innovation District. The Underdeck is a new 33 -acre open space that is slated to transform a formerly infrastructural corridor near Miami's urban core into a significant landscape and actively programmed destination for residents, workers, and visitors. The entire I-395 project will be built by the Florida Department of Transportation (TDOT"). The City of Miami will operate and maintain the open space and therefore has an important voice in every stage of the project. The concept plan for the Underdeck builds on the significant work that the City, FDOT, and others have completed over the past several years to create a broad vision and practical roadmap for integrating the City's goals, from community development to fiscal prudence, into the larger project's plan and execution. City of Miami is requesting the closure of these two roadway segments to vehicular traffic to allow for a pedestrian bridge necessary to cross the FEC Railway and embankment and to encourage east -west multimodal connectivity. Figure 1 shows the study area and the location of the roadway segments to be closed. Figure 2 shows the portion of the concept plan for the Underdeck with the proposed pedestrian bridge and the roadway segments to be closed. Page 1 Figure 1 Location Map Page 2 Figure 2 Underdeck Concept Plan Page 3 STUDY AREA The following roadway segments will be most affected by the closure of NW 1St Court and NW 13d' Street and for that reason were selected to be analyzed as part of this traffic study. • NW 1 st Place between NW 13th Street and NW 14th Street • NW 1St Avenue between NW 13th Street and NW 14th Street • NW 14th Street between NW 1St Court and NW 1St Avenue NW 1 st Place is a two-way two-lane undivided state road that provides north -south movement in Overtown. South of NW 11th Terrace, NW 1St Place turns into NW 2nd Avenue. NW 1St Place at NW 13th Street is a two-way stop - controlled intersection, whereas at NW 14th Street it is a signal -controlled intersection. Most of the land adjacent to NW 1St Place within the limits of the analysis is empty. NW 1St Avenue is a two-way two-lane undivided local road that provides north -south movement in Overtown. NW 1St Avenue at both NW 13th Street and at NW 14th Street has signal -controlled intersections. The FEC Railway runs just east of NW 1St Avenue. Most of the land on the west side of NW 1St Avenue is empty. There is some residential land use on the southwest corner of the intersection at NW 1St Avenue and NW 14th Street. NW 14th Street is a two-way two-lane undivided local road that provides east -west movement in city of Miami. NW 14' street is an important facility as it provides a connection with the Jackson Medical Center and Downtown Miami. Figure 3 shows the land ownership for parcels adjacent to the roadway closures. This information was collected using the Miami -Dade property appraiser application available in the Miami -Dade County website. Please note that access to properties located in the southeast quadrant of the intersection at NW 1 st Court and NW 14th Street will not be affected by the roadway closures because the concept plan for the Underdeck keeps access to those properties on NW 1st Court from NW 14th Street. Page 4 Figure 3 Land Ownership Page 5 TRAFFIC VOLUMES, BACKGROUND GROWTH RATE AND COMMITTED DEVELOPMENTS Given that the roadway segments under evaluation are currently closed or affected by ongoing construction for the I-395 project, it is not be possible to get meaningful information from actual traffic counts. For this reason, and after discussions with Miami -Dade County and City of Miami, it was agreed that the subject traffic analysis will use traffic data from the Downtown Miami DRI Increment III and FDOT traffic monitoring sites to assess the traffic impact of the roadway closures. These two sources for traffic data were used as follows: • 2014 and 2024 PM peak hour person trips for the roadway segments under consideration came from the DDRI Increment III. This information is included in Appendix A. • Committed trips for the roadway segments under consideration came from the DDRI Increment III. This information is included in Appendix B. It is important to note that committed trips are estimated from the unbuild developments in the DDRI Increment II and projected developments in the DDRI Increment III. • Historical AADT reports for FDOT traffic monitoring sites 878154 and 877423 were used to calculate historical growth rates for this analysis. Synopsis Report for site 877423 was used to estimate the traffic demand for NW 13"' Street. FDOT site 878154 is located on NW 14"' Street, 200 feet east of NW 2"d Avenue. FDOT site 877423 is located on NW 13"' Street, 150 feet west of N Miami Avenue. These two FDOT sites are shown in Figure 1. Historical AADT reports and Synopsis reports are included in Appendix C. Historical AADT information from the FDOT traffic monitoring sites was used to calculate an annual growth rate for the study area. A growth rate was calculated for station 878154 located on NW 14"' Street considering a lineal growth, exponential growth and decaying exponential growth methodologies. A final annual growth rate of 16.04% for this station comes from the exponential methodology, which provides the highest W of the best fit for the historical AADTs. Table 1 shows a summary of the annual growth rate calculation for station 878154. Detail calculations using the methodology from FDOT are included in Appendix D. Please note that a trend analysis was not calculated for site 877423 given that the historical traffic data results in a negative growth rate and the spreadsheet is not able perform the calculations. Table I Trend Analysis using Historical Traffic Data Notes: (1) Souce: FDOT's Florida Traffic Online (2018) 2) G R = G rawth Rate 0) Data included for Trend Analysis from 2011 to 2018 Page 6 An annual growth rate for the study area was also calculated using the Southeast Florida Regional Planning Model Version 7.0 (SERPM 7.0). The Southeast Florida model is based on the CT -RAMP (Coordinated Travel Regional Activity -Based Modeling Platform) family of Activity -Based Models (ABM). Table 2 shows the annual growth rate calculation based on the 2015 and 2040 SERPM loaded networks. Daily traffic volumes for NW 2nd Avenue, NW Ist Avenue and NW 14th Street were extracted from the 2015 and 2040 networks. The SERPM model shows that there will be a 2.07% annual growth rate. Table 2 Trend Analysis using SERPM model Weigh#ed Average 2.07% In summary, the DDI Increment III estimates an annual growth rate of 0.695°/x. Historical data from FDOT sites estimate an annual growth rate of 16.04% for station 878154 and a negative growth rate for station 877423. The SERPM model estimates an annual growth rate of 2.07%. It is important to note that the growth rate calculated from station 878154 is very high when compared to the growth rate for station 877423 and the growth rate calculated from other methodologies. Also, the AADTs from station 878154 have not been measured in all previous years and often come from estimates rather than actual field measurements. For those reasons, it was concluded that the annual growth rate of 2.07% from the SERPM model, is the most appropriate for this analysis. Page 7 TRAFFIC ANALYSIS Table 3 provides a summary of the peak hour volumes and committed trips calculations. 2014 peak volume person trips were extracted from the DDRI increment III (refer to Appendix A). These volumes were used to calculate 2040 peak volumes using an annual growth rate of 2.07% as determined in the previous section of this report. Committed trips were also extracted from the DDRI increment III (refer to Appendix B). As mentioned before, committed trips were calculated from the unbuild developments from the DDRI increment II and the projected developments in the DDRI increment III. Person trips volumes from committed developments were converted into person -vehicular trips by removing non -vehicular trips, such as: pedestrian, bicycle, walking and transit trips. In fact, Figure 4 shows that only 65.3 percent of all the committed (person trips) will be made by private automobile within Census Tract No. 34, which is the location where the roadway closures are going to take place.

In addition to these, the City of Miami's proposed Underdeck concept includes signalized pedestrian crossings at the following midblock locations where the Heritage Trail intersects surface streets with high vehicular traffic, and significant pedestrian crossings are expected: • North Miami Avenue between I-395 East Ramp and I-395 West Ramp • NE 1st Avenue between NE 11th Terrace and NE 13th Street • NE 2nd Avenue between NE 11th Terrace and NE 13th Street This memorandum analyzes the need and requirements for the mid -block signalized pedestrian crossings according to national and local standards or guidelines including: - The Manual on Uniform Traffic Control Devices (MUTCD) Chapter 4C.05 - Complete Streets Design Guidelines (Miami Dade County) - Downtown Miami Pedestrian Priority Zone (Miami Downtown Development Authority) WSP USA WSP.com STUDY AREA AND EXISTING SCENARIO The proposed Underdeck project involves the construction of a large greenspace with a shared use path for pedestrians and cyclists. It is expected that the Underdeck itself will be a large attractor of visitors throughout the day. However, it will also serve as an east -west connector between several attractors in the Downtown Miami area such as: - Frost Museum of Science, - Perez Art Museum Miami - American Airlines Area - The Adrienne Arsht Center for the Performing Arts - Knight Concert Hall - The Miami Entertainment District - Bayfront Park The existing road network and attractors are shown in Figure 1 with the area of influence highlighted. t ' Immwesl 18'hSheet t -• FYI Park'k ■ t ow ■ 3 Northwest 1611,511-1 3 3 • `` P c t 3 a 3 P P ■ 1 ■ k — „ r ■ v¢r�uart wa — t 1p t Sthool ■ Adrienne Ddphvl Expr[Ksp - .` Board ■ ■ ArsPht Center ;o o It It It .1n _ 41 O6 �� P _ _ — (:,.... ■ '071 P .—.

LiLiUL-iniF-, �I -Proposed Mid -Block Crossing Figure 2 - Proposed Pedestrian Network Page 3 WARRANT ANALYSIS The MUTCD Section 4C.05 Warrant 4, Pedestrian Volume states: "The Pedestrian Volume signal warrant is intended for application where the traffic volume on a major street is so heavy that pedestrians experience excessive delay in crossing the major street. " The standard 2A states that the volumes required to meet the definition of excessive delay is: "For I hour (any four consecutive 15 -minute periods) of an average day, the plotted point representing the vehicles per hour on the major street (total of both approaches) and the corresponding pedestrians per hour crossing the major street (total of all crossings) falls above the curve in Figure 4C-7.

Figure 3 - Pedestrian Peak Hour Warrant (Figure 4C-7, MUTCD) Projected traffic volumes are shown in Table 1 for the three proposed locations. This data has been extracted from the SR 836/1-395 From SR 9A/I--95 to Macarthur Causeway typical sections package.

The proposed roadway configuration for the I-395/SR 836/I-95 Design -Build Project is shown in Figure 4. It shows that there will be both on and off ramp access at Miami Avenue as well as connections to NE 1St Avenue and NE 2°d Avenue.

The Underdeck area today is underutilized due to vacant lots and adjacent construction. However, it is expected that pedestrian volumes will greatly exceed the thresholds defined in Figure 4C-7 due to the Underdeck development. As traffic volumes are shown to require at minimum 300 pedestrians an hour to satisfy the warrant, a pedestrian crossing is deemed necessary. At a 120 second cycle time, this is a requirement of 5 pedestrians crossing in each direction in each cycle, which is likely to be exceeded for 4 consecutive 15 -minute intervals. This area is highly urbanized, with the Underdeck re -stitching the surrounding communities and will become a safe mobility corridor. The Bicycle/Pedestrian Mobility Plan for the Miami Downtown Development Authority Area (2011), found that 6,565 pedestrians were observed to approach American Airlines Arena prior to the commencement of a Miami Heat game. Approximately 340 pedestrians were counted approaching the Performing Arts Center an hour before the performances started. Other surrounding civic centers listed in the study area section will also have significant pedestrian volumes. It is expected that many of these pedestrians will travel along the Underdeck to access these attractors within the study area. The mid -block signalized crossings provide east -west continuity along the site and not having these crossings will make this east -west corridor less enticing for pedestrians. Standard 4 states: "The Pedestrian Volume signal warrant shall not be applied at locations where the distance to the nearest traffic control signal or STOP sign controlling the street that pedestrians desire to cross is less than 300 feet, unless the proposed traffic control signal will not restrict the progressive movement of traffic. " It is expected that the adjacent signals at each three mid -block locations will incorporate heavy turning movements due to access to I-395, providing a less safe environment for pedestrians. It is deemed safer and more efficient to provide the majority of pedestrians a mid -block crossing away from the main intersections. It will also reduce the risk of pedestrians attempting to cross the road in the absence of a signal along the desire line within the center of the Underdeck, the Heritage Trail. The warrant guidance 6C states: "If this warrant is met and a traffic control signal is justified by an engineering study, then the traffic control signal should be coordinated. " As the proposed mid -block crossings will be within the vicinity of a freeway access, it is recommended that they are coordinated with the adjacent ramps, to ensure efficient flow of vehicles is not impacted. LOCAL GUIDELINES The Downtown Miami Pedestrian Priority Zone was established in January 2014 by the Miami City Commission. The ten targets of the priority zone are to: 1. Create a Clear Pedestrian Path 2. Align Curb Ramps with Sidewalks 3. Require Crosswalks at all Intersections 4. Provide Automatic Countdown Timers with More Crossing Time 5. Reduce Drive Lane Widths 6. Extend the Sidewalk at all Intersections 7. Enhance Mid -block Lighting 8. Provide Shade at Sidewalks 9. Designate 25 MPH Speed Limit 10. Prohibit Right Turns On Red These proposed crossings will assist in providing a clear pedestrian path and reducing vehicle travel speeds within the Pedestrian Priority Zone. The Miami -Dade County's Comprehensive Development Master Plan (CDMP) includes numerous policies related to Complete Streets and pedestrianism. Of note is Policy CHD-3D that states: "Update street design standards to incorporate traffic -calming measures, such as special paved crosswalks at key intersections and/or mid -block crossings, where applicable to promote pedestrian safety. " CONCLUSION Signalized mid -block crossings are deemed appropriate at the proposed locations due to the large volumes of vehicles and pedestrians both currently expected and projected to be travelling through the study area. As MUTCD Section 4C.05 Warrant 4 has been met, it is recommended that the mid -block crossings at the proposed locations be implemented for this project.
