Opportunity Areas 1. Normandy Isle (Rue Vendome) - This area has been identified in the North Beach Master Plan as a critical corridor within North Beach. Rue Vendome has been permanently closed off to vehicles and transformed into a public plaza. This street has very little shade and while Staff has started to activate this space with weekly programming, a shade structure would provide additional value.
The Administration would recommended allocating 100,000.00 for a project by Sextafeira. Page 5 of 221 The Administration would recommended allocating 100,000.00 for a project by Sextafeira. Timeline: 1 year (*The Giralda Avenue project took from March 2017 to July 2018 to plan, execute, and launch) 2. Partner with Arts in Public Places and the Office of Cultural Affairs to issue a local call for artists to commission a shade installation. This would be a unique way to foster creativity within our local artistic community. This has been done in other cities such as Houston which did a call for artists to create a shade project at Discover Green, as 12-acre park. As noted in the aforementioned examples of creative placemaking this concept has been performed throughout the country. Notably, the Bloomberg Art Challenge supports innovative, temporary art projects to promote vibrancy in cities. The Administration would recommend allocating 50,000- 75,000.00 for this project. Timeline: 6-8 months https://www.americansforthearts.org/by-program/networks-and-councils/public-art-network/public-art-year-in-review-database/firmament https://publicartchallenge.bloomberg.org/finalists 3. Perform a quick build project using temporary shade sails of various colors. This method would be the quickest way to provide shade over identified areas. Shade sales range in price but would cost around 30,000.00. While this approach could provide a practical enhancement to an area, this tactic would not spur the same traction as the Umbrella Project did for Giralda Avenue, nor would it have a curated artistic component. A budget of 30,000.00 would allow for 2-4 shades to be installed which could be performed by City Staff.
The following counts were concluded: 41st Street: 8 vacancies Lincoln Road (100 block - 1100 block): 23 vacancies Washington Avenue (5th-15th Street): 55 vacancies Ocean Drive: 10 vacancies North End (63rd to 70th Street): 21 vacancies Concurrently, Staff began further reviewing and researching background information for each of the vacant storefronts, with the specific intent to identify the reason for extended vacancy and to identify any barriers that might be alleviated at the City level. This study includes cross-referencing each address with the City's BTR registry along with vetting each address through property appraiser and Sunbiz to determine ownership. We also Page 7 of 221 reviewed all permits that are currently active with the Building Department. A full spreadsheet of this information is attached (Exhibit B). Through this process we were able to identify that 15 of the properties mentioned above had active permits and were currently under construction or in the process of redevelopment. This information allowed for Staff to begin outreach to better understand the challenges and issues brokers and property owners have been facing in finding new tenants. Staff contacted all of the brokers that were identified through Sunbiz and/or property appraiser that represented the properties surveyed. Unfortunately, many of these representatives did not provide information or respond to our inquiries. Therefore, we began to survey additional industry professionals in the community (Business Improvement District, Miami Beach Chamber of Commerce, and individual property owners in Miami Beach).

Broadband in Miami Beach is currently provided by digital subscriber line (DSL), cable, fiber optic, and satellite. Cable and DSL are the most widely used broadband service method, with coverage across approximately 98 of the City.
Table 1.1 summarizes the characteristics of the different broadband service types available in Miami Beach. Table 1.1: Comparison of Broadband Service Types in Miami Beach Broadband Service MethodParameter of Comparison DSL Cable Fiber Optic Satellite Speed of connection Slowest Fast Fastest Slow Potential for lag in service Common1 Common2 Uncommon Common3 Availability Wide Wide Limited Wide
Wired broadband infrastructure, including DSL, coaxial cable, and fiber optic cable, are traditionally installed separately from the sewer infrastructure. Broadband infrastructure may be installed above or below ground. Above ground, aerial cables are affixed to power or telephone poles. Below ground cables are most commonly installed via open trench and are protected by PVC or galvanized steel ducts. Underground installation may also be completed via horizontal directional drilling (HDD), which is the process of reaming an arced pathway which cables can be pulled through. Trenchless technology such as HDD is less disruptive to the public and environment. In Miami Beach, the broadband network provider is responsible for installation, operation, and maintenance of the system. Sewer systems are installed below ground by open trench or through trenchless technology, such as tunneling or HDD, when necessary. The City of Miami Beach is responsible for installation, operation, and maintenance of its sewer system. Small diameter sewer pipes service homes and businesses while larger diameter pipes collect flow and are typically located closer to pump stations. Currently, the City s sewer network is comprised of approximately 113 miles of below ground gravity sewer and 2,750 manholes which allow access to the sewers at regular intervals.
Crew-accessible sewers are defined by CableRunner as sewers with a diameter of greater than 80 cm (30 in). A human crew enters the sewer and manually affixes cables to the wall of the pipe with mounting clips at pre-defined intervals. The depth that these clips are driven into the pipe wall depends on the pipe material and wall thickness. The mounting clips hold 8.2cm x 3.6 cm (3.2 x 1.4 ) rectangular cable trays in place. The cable trays run along the length of the pipe and are used as a conduit for fiber optic cables. Figure 2-1 shows CableRunner technology installed in a crew accessible sewer. Page 27 of 221 Page 7 of 19 CableRunner Technology Review City of Miami Beach
A key element to the functionality of the CableRunner system is redundancy. Ideally, the system would be very interconnected and have multiple pathways for each connection, to assure reliable uninterrupted service. CableRunner s intent is to install fiber optic connections through multiple pathways, so in case of an interruption in service along one pathway, there are backup pathways to maintain service. The interconnectivity of a sewer system to homes and businesses makes it a potential conduit for installation of a fiber optic network. Table 2.1 summarizes the installation requirements for CableRunner technology, as discussed above. Page 29 of 221 Page 9 of 19 CableRunner Technology Review City of Miami Beach Table 2.1: CableRunner Installation Requirements Parameter Capability of Installation Condition of Pipe Damage Class 1-3 CableRunner may perform installation. Damage Class 4-5 Pipe in too poor condition for CableRunner installation. Pipe Diameter 4-10 Too small to access via robot or crew. 12-27 Accessible via robot. 30-36 Accessible via crew. Pipe Material Concrete Bolts are drilled partially through wall of pipe. The depth of the bolts
As discussed in Section 2.2, CableRunner classifies a crew-accessible sewer as one that is greater than 80 cm (30 in) in diameter. According to CableRunner s size classification, less than 1 of City s sewer system is crew-accessible. The current version of the CableRunner robot is able to install cable trays in sewers greater than 30 cm (12 in) in diameter. As presented in Table 3.1, approximately 23 of the City s existing gravity collection system is robot accessible. The remaining 75 of sewer system of known diameter is too small to be accessed via either crew or robot.
Table 3.2 presents a breakdown of the City s sewer system by material. A majority (approximately 54.5 ) of the City s existing gravity sewer system is constructed out of terracotta pipe. Terracotta pipe is very susceptible to cracking once an initial fracture is made. Drilling bolts partially or fully into a terracotta sewer pipe for mounting of cable trays could compromise the structural integrity of the pipe and likely lead to leakage. The second most common material of construction for Miami Beach sewer is concrete (37.3 ). CableRunner has previously successfully installed fiber optic cables in large diameter concrete tunnels and pipes. Other materials within the City s sewer system include PVC (7.6 ) and Ductile or Cast Iron (0.3 ), which can better structurally support CableRunner technology.
As discussed in Section 2.2, prior to installation CableRunner performs a Damage Class evaluation and will not install on pipes assigned a Damage Class of 4-5, or a pipe that may need replacement within 10 years. Although the exact age distribution of the existing gravity sewer piping is unavailable, the major presence of terracotta piping indicates that a majority of the sewer system was installed circa 1950, making the system almost 70 years old. The US Environmental Protection Agency (EPA) issued a document in September 2002 titled Clean Water and Drinking Water Infrastructure Gap Analysis Report (document no. 816-R-02-020). This report indicates that the average expected useful life of gravity sewer piping is in the range of 80-100 years. The majority of the City s sewer piping is approaching this age threshold and will likely need a great deal of replacement and repair within the next 10-20 years. Comprehensive repair and replacement of an aging sewer system takes many years and resources. 3.3.2 Repair The CableRunner team is responsible for the maintenance of the CableRunner system. If the City must repair or replace a pipe where CableRunner is installed, the CableRunner team must be contacted to splice the cables as necessary and install a manhole to manhole cable bypass system to ensure that broadband customers do not lose service during the pipe repair. If enough redundancy exists, the CableRunner team may not need to install a bypass, but the system will still need to be removed for the City to perform the pipe repair. Following the repair, CableRunner must be present to reinstall the cable trays. The added step of coordinating with an additional crew can lead to longer repair times and potentially greater public disruption, which may be especially problematic in emergency repair situations. 3.3.3 Lining One common maintenance technique used on failing sewer pipes is lining. Cracked or damaged sewer pipe may be internally lined through cured-in-place piping (CIPP) or similar trenchless methods. CIPP is the process by which a flexible lining material containing fiber glass particles is inserted into the sewer pipe. Water is pumped through the liner so that it expands to the walls of the sewer pipe. The water is heated, which causes the liner to harden, essentially forming a new internal wall of the pipe. A pipe could not be lined with CableRunner technology present. The CableRunner crew would need to be contacted to install a bypass and remove the cable trays before lining could take place. This adds extra time and resources to a lining procedure. Commonly, the liner material is thin, as not to impact the hydraulic carrying capacity of the sewer pipe. The thickness of a liner does not often exceed one inch, as presented in Table 3.3. Attaching cable trays Page 36 of 221 Page 16 of 19 CableRunner Technology Review City of Miami Beach to the liner may penetrate the surface of the liner, potentially resulting in leaks and possibly voiding the liner warranty. As presented in Table 3.4, half of all sewer piping in Miami Beach has been lined. Table 3.3: Average Sewer Pipe Liner (CIPP) Thickness
3.3.4 Maintenance Inspection and maintenance is necessary for all sewer systems. A single clogged sewer pipe can compromise the functionality of the entire system. If a blockage or build-up is suspected, the City uses robotic cameras on wheels to perform an in-sewer TV inspection of the line.
The United States Geological Survey (USGS) records daily groundwater levels at various monitoring wells across the US. Well No. F-179 (254444080144801) is located at the intersection of SW 32 Avenue and SW 24 Terrace in Miami, Florida. The average wet season groundwater elevation for 2017 was 0.90 NAVD 88 and the average dry season groundwater elevation for 2017 was 0.75 NAVD 88. Table 3.5 shows the range of invert elevations of the City s gravity sewer. Approximately 90.5 to 99.5 of the entire gravity sewer system is below the groundwater table for the entire year. 90.5 conservatively assumes that all pipes of unknown elevation are above the water table, while 99.5 assumes that all pipes of unknown elevation are below the water table.
The majority of the gravity sewer is too small in diameter for installation by either human crew or the CableRunner robotic device. It is not advisable to drill into terracotta piping due to the limited knowledge of its physical condition. Drilling into existing piping regardless of the material will increase the potential for I/I problems that Miami Beach already faces due to the depth of pipes below the water table and the age of its sewer infrastructure.

ANALYSIS: On June 8, 2016, the City Commission, pursuant to Request for Qualifications (RFQ) No. 2016-124-KB, adopted Resolution No. 2016-29425 accepting the recommendation of the City Manager and awarded Desman, Inc. (Desman) a contract for Architectural and Engineering Design Criteria Professional Services For Mixed-Use Parking Garages. On October 21, 2016, the Neighborhoods and Community Affairs Committee (NCAC) heard a presentation exploring the construction of an all-wheels park at one of three locations in the North Shore area. The Committee selected the 72nd street parking lot (P-92) as the preferred location and requested additional information regarding parking and other uses. The site is located between 72nd and 73rd Streets, and between Collins and Harding Avenues. The item was discussed at the following committee meetings, November 18, December 9, 2016 and January 27, February 17 and March 17, 2017. On February 8, 2017, the City Commission referred a discussion item of a skate park at the 72nd Street parking lot (P-92) to the Finance and Citywide Projects Committee (FCWPC) and on March 31, 2017 FCWPC directed staff to work with Commissioner Aleman in developing possible footprints, volumetric analysis, area available for other uses and number of parking spaces. On April 26, 2017, the City Commission adopted Resolution No. 2017-29843 directing the City Administration to proceed with a consultant service order engaging Desman to prepare a feasibility study for a parking garage structure, and a new recreational park with a skate park and community use space, at the 72nd Street municipal parking lot (P-92). The Commission further directed the City Administration to prepare a budget item request for consideration of the project in the City s Capital Budget fiscal year 2017-2018. At that time, the Commission referred the feasibility study for this project to the FCWPC. On May 17, 2017, the City Commission approved a Capital Budget Amendment to the fiscal year 2016/2017, to prepare the initial feasibility study and preparation of renderings of the 72nd Street Park and Parking Structure. As the first step in developing the Design Criteria Package (DCP), Desman was engaged to commence the feasibility study and design options, and began meeting with the City s Parking, Parks and Recreation, Public Works, Office of Capital Improvement Projects (CIP) and Planning departments. Discussions with the various departments established project programming, planning/code constraints and other requirements. On January 19, 2018, subsequent to referral by City Commission on January 17, 2018, FCWPC directed staff Page 45 of 221 to meet with Commissioner Aleman and Desman to explore lower scale, larger footprint options and bring them back with other options. On January 22, 2018, Commissioner Aleman met with CIP and Desman to review the options and discuss other possibilities. On February 14, 2018, the City Commission referred the project to the FCWPC to discuss including a competition-sized swimming pool in the project and on February 23, 2018, the FCWPC discussed and recommended adding the pool, with support facilities, to the feasibility study. On March 7, 2018 the City Commission accepted the recommendation of the FCWPC to include a competition- sized pool (aquatic center) in the feasibility study for the proposed 72nd Street mixed-use project. On March 8, 2018, the Parks and Recreational Facilities Advisory Board, as described in Letter to Commission (LTC) 132-2018, made a motion for the City to prioritize building an aquatic center in the City of Miami Beach. On May 3, 2018, as described in LTC 249-2018, the Parks and Recreational Facilities Advisory Board passed a motion identifying potential sites for the aquatic center as the 72nd Street parking lot (P-92), Flamingo Park or the Scott Rakow Youth Center, and asked that money be set aside in the 2018 General Obligation Bond and for that money to be portable to accommodate a location once identified. On April 20, 2018, the FCWPC deferred discussion and review of this project to the June committee meeting, pending completion of the feasibility study. On June 8, 2018 the FCWPC heard a presentation of four (4) conceptual options, developed by Desman, for the proposed 72nd Street Mixed-Use Project. All four options addressed planning requirements and took the North Beach Master Plan into consideration. The variations reflected options in orientation, circulation and arrangement and included the following programming elements: Parking garage that can be converted to some other use in the future, having a maximum of 500 spaces Structure and Active Liner arranged to reinforce commercial corridor at southwest corner of site All-wheels park up to 20,000 SF in size 5,000-10,000 SF Library/Media Center Roof-top Community Pool measuring 50m x 25m, including all support facilities, with movable bulkheads and movable floor (high school competition model) Roof-top community meeting room up to 5,000 SF, potentially part of the Library Approximately 20,000 SF of civic/commercial space Adult focused, upscale fitness gym with running track Passive Park measuring approximately 56,000 SF The FCWPC recommended the following items to the proposed 72nd Street mixed-use project: Delete the all-wheels skate park and relocate to the West Lots Library component is mandatory Locate running track on grade Incorporate resilient and sustainable elements Provide an active park in lieu of passive park The FCWPC directed staff to meet and coordinate with the Parks and Recreational Facilities Advisory Board, Corradino Group working on the Ocean Terrace Neighborhood Master Plan and the developers of the Mixed Use Project on the south side of 72nd Street.
1. Architecture of Individual Garage Structures: Virtually all of our parking structures in the City (both public and private) each have a unique and distinct architectural identity. NONE were designed in a manner that could accommodate large advertising banners. The introduction of these large advertisements would significantly impair the architectural integrity of the garages. In furtherance of this, attached is a short piece, published in 2011, entitled BEEN THERE HAVEN'T DONE THAT Miami's Beached Cars . It nicely Page 49 of 221 and succinctly summarizes the architectural value of the City's parking structures. 1. Visual Blight and Urban Design Standards: Citywide, Miami Beach is a very unique concentration of well-planned and cohesive architectural forms. We have architectural representation from numerous eras both inside and outside of our historic districts. The introduction of large ads on parking structures will significantly compromise this carefully balanced urban form. CONCLUSION: Each of these options provide their own unique set of opportunities. Upon internal discussion, it was decided that both the sponsorship and trolley exterior advertising options could be relatively easy to move forward with and begin generating additional alternative revenue. Both of these options could be started through our procurement department or working with other municipalities to piggy-back off of any current contracts that may already exist. Exterior advertising on our parking garages, fleet building or anywhere else in the city may require additional discussion. Staff is seeking further direction from the Finance and Citywide Committee on these items.
