Executive Summary In 2016, the Hillsborough County Economic Development Department created the Targeted Redevelopment Program to enhance and encourage development within several pilot areas. The primary objective of the program is to encourage private sector investment in sites and buildings that will encourage retention and attraction of businesses and jobs for the communities identified as pilot areas. One of these pilot areas is the 56th Street Redevelopment Area. The purpose of the Infrastructure Assessment is to evaluate how well the current transportation, utility, and stormwater infrastructure will support infill, redevelopment, and economic development in the 56th Street Redevelopment Area, consistent with the Targeted Redevelopment Program goals. This Infrastructure Assessment includes a Transportation Assessment (page 16) identifying locations for capacity, safety, mobility, and roadway condition improvements based on context sensitive users including pedestrians, cyclists, commuters, freight and commercial vehicles. The improvements identified in the Transportation Assessment seek to improve the roadway conditions of users and connections that promote development in the study area. Improvements in the highest areas of need include intersection safety improvements, complete street improvements including speed management and dedicated user facilities, and pavement rehabilitation or preventative treatments. The Utility Assessment (page 38) estimates the available water and wastewater treatment plant capacity and potential transmission line upgrades necessary to better serve the existing development and support infill and redevelopment in the study area. Improvements in the highest areas of need include sewer system extension, converting septic to sewer facilities, and water system extension or replacement. The Vulnerability Assessment (page 46) identifies areas with the highest flood potential. These locations should be a focus of flood mitigation and adaptation strategies to improve conditions for the existing development and promote redevelopment in the study area. Improvements in the highest areas of need should include roadway and area flood exposure treatments which could include but is not limited to hardening and elevating infrastructure, additional stormwater storage, bioswales, and landscaping. The recommended actions (page 54) are a summary of the assessment findings and identification of the highest areas of need and respective recommended infrastructure improvements. A map of the recommended improvements is shown on page 57, Figure 20. A summary of assessment measures and improvement benefits is provided in the Assessment Matrix in Appendix A. The matrix may be used to further prioritize and identify improvement projects following more detailed project scope definition through analyses, public outreach and coordination with responsible parties including Hillsborough County departments, City of Tampa, Florida Department of Transportation and CSX.

Section 1 Introduction and Context
Introduction and Context Background
In 2016, the Hillsborough County Economic Development Department created the Targeted Redevelopment Program to enhance and encourage development within several pilot areas. The primary objective of the program is to encourage private sector investment in sites and buildings that will encourage retention and attraction of businesses and jobs for the community identified as pilot areas. One of these pilot areas is the 56th Street Redevelopment Area. The 56th Street Redevelopment Area, located in central Hillsborough County, is comprised of approximately 1,030 gross acres of land. As shown in Figure 1 , the redevelopment area is bounded by E. Sligh Avenue to the north, Hillsborough Avenue/State Road 580 to the south, Orient Road to the east, and 50th Street/State Road 583 to the west. Key elements within the study area include NetPark Tampa Bay (formally known as the Eastlake Square Mall) and a freight rail line that diagonally traverses the study area. The redevelopment area also borders the Seminole Hard Rock Hotel & Casino that is located south of Hillsborough Avenue and east of Orient Road. The expansion of NetPark and the Seminole Hard Rock Hotel & Casino will require thoughtful planning for the future. Project Purpose The purpose of this assessment is to evaluate the current infrastructure in terms of how well the 56th Street Redevelopment Area will support infill and redevelopment consistent with the economic development goals for the area. The infrastructure assessment, including a resiliency analysis, is the starting point to determine future investment and make infrastructure decisions. Another consideration of this study is the relationship between the redevelopment area as a whole and the surrounding major activity centers and future expansion opportunities. This infrastructure assessment provides recommendations that Hillsborough County can consider and implement as part of continued planning efforts in the 56th Street Redevelopment Area. The recommendations focus on identifying current inadequacies in the existing critical infrastructure, as well as opportunities to plan for enhanced infrastructure. A critical element in the assessment will be providing recommendations to improve the resiliency of the existing infrastructure in the redevelopment area.

Study Area Context Study Boundary
The study boundary was developed based on the Redevelopment Area, as shown in Figure 2 . The study boundary shown in the dashed black line is bounded north of E. Sligh Avenue, south of Hillsborough Avenue/State Road 580, east of Orient Road, and west of 50th Street/State Road 583. Existing Land Use There are numerous categories of existing land uses within the redevelopment area which are primarily non-residential. Shown in Figure 3 , the majority of existing land uses include industrial, commercial, public/quasi-public/institutions, and vacant land. There are some residential uses, single- family and multi-family, located near the southeast and northwest corners of the redevelopment area. Community Facilities The 56th Street Redevelopment Area includes several community facilities within the redevelopment area boundary. The community facilities include schools, libraries, parks, and emergency management/police/fire. The community facilities in the redevelopment area are identified in Figure 3 . The area contains two high schools, one fire station, and one large park which also includes a community center. The two high schools located in the redevelopment area are King High School and Tampa Bay Technical High School. King High is located near N 56th Street and E Sligh Avenue, and Tampa Bay Tech is located near Orient Road and E Sligh Avenue. Table 1 shows existing and projected school capacities to the 2024-2025 school year based on Florida Department of Education Florida Inventory of Schools Houses (FISH) data. Both high schools have available capacity and are not projected to reach maximum capacity through 2025. Table 1. Existing and Projected School Capacities

Business and Demographics An estimated 249 businesses are located in the study area that support 3,680 employees, based on 2021 ESRI Business Analyst data. The breakdown of businesses by North American Industry Classification System (NAICS) category are shown in Table 2 . Retail Trade and Wholesale Trade businesses, and Other Services make up the largest percent of total businesses in the study area at 36.1%, and 30.4% of the employees. These trades include the businesses across the study area including supply and food stores, repair and maintenance shops, and other commercial and personal services. The other significant businesses in the area include construction and engineering services, and warehousing and distribution centers. Many of the businesses are accessed by freight and truck, requiring a large footprint for parking lots and rail right-of-way. The United States Census Bureau tool, OnTheMap, was used to identify employee inflow and outflow within the study area based on most recently available data (2019). According to the OnTheMap application, approximately 97% of the labor market (employees in the area or residents in the area) comes from outside of the study area. The remaining labor market includes 3% who leave the study area for work, and less than 1% who live and work in the study area. The 56th Street Redevelopment Area has an estimated population of 397 people and 124 households, based on ESRI 2021 projections. Residential uses are located on the edge of the study area including single-family homes on Orient Road, and multifamily homes on Sligh Avenue and 50th Street. Vulnerable populations in the study area include those 65 years old or older, and households with a median income less than the county average or income less than $25,000. When compared to Hillsborough County as a whole, the study area has a higher percentage of population that is 65 years old or older, a lower median household income, and higher percentage of households with income below $25,000, than that of Hillsborough County. A comparison of socioeconomic statistics for the study area and Hillsborough County is provided in Table 4 .

Future Land Use and Planned Development The primary future land use in the redevelopment area is identified as Light Industrial. There is a portion of the redevelopment area that is categorized as office commercial and community mixed-use at Orient Road and Hillsborough Avenue. The Public/Quasi-Public future land uses are government- owned land which includes King High, Tampa Bay Tech, and the Hillsborough County Schools Logistics Warehouse. Currently, there are approximately 224 acres of Planned Development (PD) within the redevelopment area. One PD area includes a 27-acre industrial site that is currently under development construction, located along Harney Road between Hillsborough Avenue/US 92 and Hanna Avenue. This site is an example of a Competitive Site, defined by the Hillsborough County Economic Development Department. The Competitive Sites Program identifies locations with the capacity to support targeted industry office/industrial development and crafts policies and programs to guide public sector engagement and investment to meet economic development objectives. Most competitive sites have an approved Planned Development or Development of Regional Impact (DRI) Development Order with a minimum of 100,000 square feet of office and/or industrial entitlements or the site has appropriate zoning that allows for a minimum of 100,000 sf of office/industrial targeted industry development. Competitive sites located in the redevelopment area have a lower threshold with a minimum of 50,000 square feet. The redevelopment project locations shown in Figure 5 are part of Hillsborough County’s Targeted Redevelopment Grant program. The grant program targets development and uses in areas that are traditionally seen as declining in value or are underutilized relative to their location and existing built infrastructure. In the 56th Street Redevelopment Area, these sites include site development and construction for manufacturing and warehouse uses. In the 2017 Market Analysis for the redevelopment area, five Key Vacant Buildings were identified as qualified sites for multiple incentives including site permitting review and fee assistance, grants for site development and improvements, and intentional marketing strategies for qualified properties. Of the five vacant properties identified in the analysis, all five are now occupied warehouse spaces and one property is a part of the redevelopment grant program. In addition to vacant space becoming leased, the market analysis estimated an additional demand of 100,000 to 325,000 square- feet of net new industrial space by 2023. These estimates are based on job growth forecasts by the Florida Department of Economic Opportunity and do not include redevelopment generated through the County’s Targeted Redevelopment Grant Program.

Transportation Assessment Section 2
Transportation Assessment The 56th Street Redevelopment Area is bounded by state owned principal arterial Hillsborough Avenue to the south, County owned collector roadways Orient Road and Sligh Avenue on the east and north, and 50th Street on the west. Arterial roadways 56th Street and Harney Road bisect the study area and provide access to employment areas for vehicles and trucks but present barriers for vulnerable users like pedestrians and cyclists. Hanna Avenue is also a collector roadway and a designated truck route between 56th Street and Harney Road. The roadways within the study area have a Suburban Residential, Commercial or Town context classification which is envisioned to include user facilities for higher non- vehicle activity. The roadway classifications and characteristics are described further in the following Transportation Assessment. Congestion Management Roadway Level of Service Peak volume to capacity (v/c) data from the 2019 Level of Service (LOS) Report was reviewed as the most recently available data due to COVID-19 impacts to traffic conditions. Capacity is based on the adopted LOS for each roadway. A v/c ratio of 1.00 or greater indicates that the volume exceeds the capacity of the road and indicates areas with a high amount of peak congestion. The roadway v/c ratios and average daily traffic are shown in Table 5 and Figure 6 . Table 5.

Travel Time Reliability To measure travel time reliability, Travel Time Index (TTI) data was documented from Iteris Clearguide for 2019. The Travel Time Index is the ratio of the travel time during the peak period to the time required to make the same trip at free-flow speeds. The TTI was documented for the a.m. peak- hour period (7 a.m. to 9 a.m.) and the p.m. peak-hour period (4 p.m. to 6 p.m.). The morning and evening TTI indicate travel times greater than 20% of the free-flow speed travel time in both directions for all study roadways except Sligh Avenue. Sligh Avenue has travel times greater than 10% in the westbound direction and typical travel times in the eastbound direction in the morning and evening. Trucking and Freight As defined in the Hillsborough TPO’s 2016 Freight Logistics Zone Strategic Plan, the 56th Street Redevelopment Area is within a logistics cluster as an existing center of freight activity. As a result of the industrial uses and freight-oriented businesses, several truck routes and rail lines connect into the redevelopment area. To best serve those uses, it is important for the routes to be reliable from a travel time and pavement condition perspective. Truck routes are shown in Figure 9 with underlying p.m. peak-hour TTI, and in Figure 10 with the underlying pavement condition. Pavement condition is discussed further beginning on page 24. As noted in the Market Study for the redevelopment area, CSX representatives have determined several of the existing tracks and spurs in the area are not maintained or owned by CSX. The mix of CSX and private ownership limits the ability to improve rail connections that can ultimately improve the shipping activity in the area and region, an expressed interest by CSX. The tracks and spurs owned by CSX are shown in Figure 10 . Based on rail volumes from the Federal Railroad Administration, 1 train per week operates on the CSX track (Neve Spur) in the 56th Street Redevelopment Area. This spur has low utilization compared to the activity countywide which may be attributed to the termini within the redevelopment area and the close proximity to the Tampa Terminal rail yard. The CSX freight rail use has been reviewed by agencies throughout the region for potential passenger use for over 10 years. Although this segment of the CSX track would not be recommended for passenger use, it connects to other segments that may provide regional commuter rail potential.

Resurfacing Roadway pavement condition inventory for all non-state roadways within the study area boundary is based on pavement condition data from July 2021. Roadway pavement condition is scored out of 100 to indicate the pavement condition index (PCI). Hillsborough County’s pavement condition target is 55. Approximately 9,343 feet of roadway in the study area are below the target condition. This is approximately 15% of the total linear feet of roadway (63,297 ft) in the study area with a PCI score below 55. Figure 11 shows roadways with the following score categories: Good, Fair to Satisfactory, Poor to Very Poor, and Serious to Failed. Figure 11 also shows the planned, unfunded resurfacing projects within the redevelopment area including Hanna Avenue from 50th Street to Harney Road, Parke E Boulevard, and Pine Grove Road.

Mobility and Safety Multimodal Facilities
Multimodal facilities provide non-vehicle connections to destinations and activity centers. Multimodal facilities in the redevelopment area include sidewalks, bicycle lanes, and connections with Hillsborough Area Regional Transit Authority (HART) routes and stops. Sidewalks are available along E Sligh Avenue, N 50th Street, and Orient Road. There are also fragmented portions of the sidewalk located along Harney Road shown in Figure 12 . Bicycle facilities are not as readily available as sidewalks in the study area but are available on state roads N 56th Street and Hillsborough Avenue. FDOT is currently conducting a planning study along N 56th Street to evaluate potential multimodal solutions and it is anticipated to be complete in October 2022. Another ongoing study for multimodal improvements includes 56th Street from Sligh Avenue to Busch Boulevard. This roadway has been identified by the Hillsborough Transportation Planning Organization (TPO) as one of the top high injury network facilities and a priority for Vision Zero. The high injury network is based upon the highest numbers of fatalities and injuries per mile. Additional planned and programed multimodal and safety improvements in the redevelopment area include funded School Route Safety Improvements for King High School. Unfunded pedestrian improvements include Orient Road from Hillsborough Avenue to Sligh Avenue, Sligh Avenue from Harney Road to Oakdale Drive, and Harney Road from Hillsborough Avenue to Hanna Avenue. HART provides transit service in the redevelopment area via Route 6 and Route 39 on N 56th Street, Route 38 on E Hillsborough Avenue, and Route 48 on Harney Road. Along these routes, the stops at the intersection of Hillsborough Avenue & Orient Road have the highest daily average ridership activity in the redevelopment area. The stop located south of Sligh Avenue & N 56th Street on the west side of 56th Street also experiences high ridership activity compared to other stops in the redevelopment area, shown in Figure 13 . Funded transit improvements identified in HART’s Transit Development Plan (TDP) in the redevelopment area include 15-minute frequency enhancements for Route 6 and Route 39.

Intersection safety improvements are recommended at the following intersections based on a pattern of crash types identified at the locations. Improvements for state road-to-state road intersections are not included. • N 50th Street & Diana Street : due to the reported angle crashes, including one resulting in a serious injury, intersection safety improvements could include access management strategies and lane geometry including review of the intersection skew. • Sligh Avenue & N 56th Street : based on the high number of reported angle and left turn crashes, intersection safety improvements could include signal timing and phasing adjustments and review of sight distances and traffic control visibility. Improvements should also take into consideration existing conditions of pedestrian facilities at the intersection as there was a pedestrian involved crash. • Harney Road & Sligh Avenue : based on the high number of reported angle and left turn crashes, intersection safety improvements could include geometric improvements due to the intersection skew and signal adjustments to include protected left-turn phases. • Harney Road & Hillsborough Avenue : based on the high number of reported left turn crashes, intersection safety improvements could include signal timing adjustments and review of sight distances and traffic control visibility. Improvements should also take into consideration existing conditions of pedestrian facilities at the intersection as there was a pedestrian involved crash. • Orient Road & Hillsborough Avenue : based on the high number of reported sideswipe and left turn crashes, intersection safety improvements could include signal timing and phasing adjustments and review of sight distances and traffic control visibility. It should be noted that the fatal crash was reported at this intersection.

Context Classification Context Based Classifications have been defined for all the County maintained roadways and prioritize the users of the roadway to best serve them and support the adjacent land use and development patterns. Context Based Classifications provide a link between land use and transportation planning efforts by defining overall development patterns and form for Collector and Arterial roadways. Along with Context Based Classifications, the Complete Street Guidebook and County Design Manual provide guidance to implement appropriate street improvements for the context of the roadway, travel modes, and community environment. Hillsborough County’s Context Based Classification system includes five contexts derived from Future Land Use Community Plans - Rural, Suburban Residential, Commercial, Town, and Urban General. The context classifications of County roads in the 56th Street Redevelopment Area include Suburban Residential, Suburban Commercial, and Suburban Town. As indicated in Table 9 , Harney Road and Orient Road currently have a posted speed limit that is greater than the target speed for their respective context classifications. It is recommended to implement speed management strategies in order to reduce the posted speed limit based on the target context classification speed. Each context classification includes typical section design elements that are designated as high and low priority. The missing required elements identified in Table 9 are considered high priority for each context classification and are recommended improvements for the roadways.

Transportation Infrastructure Assessment Findings
The Transportation Assessment included a review of the existing roadway conditions along Hillsborough County maintained roadways and state facilities based on available data. The review of congestion, mobility, and safety conditions included data for volume to capacity ratios, travel time index, Context Classifications, pavement conditions, existing truck routes, existing HART routes, and crash patterns. Based on a review of the existing volume to capacity ratios and Context Classification considerations, the following roadways are recommended for complete street and safety improvements which could include speed reduction, improved facilities for all modes, and congestion reduction measures: • 50th Street from Clifton to Hanna Avenue • Hanna Avenue from 50th Street to Harney Road • Harney Road from Hillsborough Avenue to Sligh Avenue • Orient Road from Hillsborough Avenue to Sligh Avenue • Sligh Avenue from 52nd Street to Orient Road • 56th Street from Hillsborough Avenue to Sligh Avenue • Hillsborough Avenue from 56th Street Orient Road
Intersection safety improvements are recommended at the following intersections based on a pattern of crash types. Improvements should take into consideration access management strategies, lane geometry, existing pedestrian and bike facilities, and sight distance, following a detailed safety analysis at the intersection locations.
• N 50th Street & Diana Street • Sligh Avenue & N 56th Street • Harney Road & Sligh Avenue
• Harney Road & Hillsborough Avenue • Orient Road & Hillsborough Avenue
Based on the pavement condition index of County maintained roadways in the study area, the following roadways have poor to very poor pavement condition and are recommended to be considered for major rehabilitation: • Hanna Avenue from 50th Street to 54th Street • Hanna Avenue from Pine Grove Road to Orient Road • Diana Street from 50th Street to 56th Street
To further identify the project scopes for the transportation improvements, identifying the required funding sources, public engagement, and coordination with partner agencies including the City of Tampa and Florida Department of Transportation, should be completed.

Utilities and Services Assessment Section 3
Utilities and Services Assessment Central Services
This analysis identifies the water/sewer service provider, water and wastewater treatment plant permitted capacities, and locations of large water/ sewer transmission infrastructure within the 56th Street Redevelopment area. Traffic Analysis Zone (TAZ) data and future land use data from 2015 to 2045 were used to determine future population growth in the study area. Hillsborough County and City of Tampa utility GIS files, 2018 City of Tampa Howard F. Curren AWTP Phase 2 Master Plan Report, 2018 City of Tampa Master Plan Report – Potable Water Master Plan, Florida Department of Environmental Protection (FDEP) permit data, and 2018 Hazen and Sawyer Hillsborough County Septic Tank Conversion – Neighborhood Prioritization Report were used to analyze the existing utility infrastructure. The projected water demand and wastewater flow increase was estimated from the future population growth to determine if there is enough capacity available to support the anticipated growth in the redevelopment area. The 56th Street Redevelopment Area existing water and wastewater collection and transmission systems are both managed by the City of Tampa. Hillsborough County utilities does not serve this service area. The David L. Tippin water treatment plant (WTP), managed by the City of Tampa, provides treated potable drinking water to the 56th Street Redevelopment Area. Wastewater flows in the study area are collected and treated at the Howard F. Curren Advanced Wastewater Treatment Plant (AWWTP), managed by the City of Tampa. Future Land Use/Growth A map showing the future land use of the 56th Street Redevelopment Area is included in Figure 4 . The primary land use of the 56th Street Redevelopment Area is light industrial. There are also large sections of research corporate park, public/quasi-public, and office commercial land; community mixed use and heavy industrial land account for only a small portion of the study area. Based on the future land use from the provided TAZ data, Hillsborough County population projections in the 56th Street redevelopment area are not expected to have an increase in population from 2015 to 2045 and the water and wastewater system flow is not anticipated to increase due to population increase as shown in Table 10 .

Existing Public Water and Wastewater Capacity Water Treatment Plant Capacity
The 56th Street Redevelopment Area water is served by the David L. Tippin WTP. As reported in the 2018 City of Tampa Master Plan Report – Potable Water Master Plan, this potable water treatment facility has a maximum flow of 120 million gallons per day (MGD) and an annual average daily flow of 81 MGD. There is 39 MGD of available potable water production capacity at the water treatment plant. Wastewater Treatment Plant Capacity The 56th Street Redevelopment Area wastewater is treated by the City of Tampa Howard F. Curren AWWTP. As reported in the 2018 City of Tampa Howard F. Curren AWTP Phase 2 Master Plan Report, the treatment plant has a permitted capacity of 96 MGD, with an annual average flow of 60 MGD and a maximum hourly flow of 190 MGD. This leaves 36 MG of available wastewater treatment plant capacity (annual average flow) for new development or redevelopment if needed. See Table 10 below for a summary of the capacity analysis.

Existing Public Water and Wastewater Large Transmission Mains Water
The water infrastructure in the 56th Street Redevelopment Area is owned and managed by the City of Tampa. The study area has one major water main: 42” water main running east on E Hanna Avenue, turning south on N 56th Street, and continuing east on E Hillsborough Avenue. According to City of Tampa GIS records, this transmission main is ductile iron and was installed in 1989. Since ductile iron pipe has a service life expectancy of 50 or more years so this main should have a fair amount of remaining useful life. Figure 16 is a map of the existing water distribution infrastructure in this area. Wastewater Several wastewater force mains owned by the City of Tampa run along the boundaries of the redevelopment area ranging from 12-inch to 4-inch. A 12-inch cast iron force main runs along E Sligh Avenue on the north edge of the redevelopment area. Cast iron force main stopped production/ installation in the 1980’s and was replaced with ductile iron pipe/PVC pipe. It is expected the 12-inch cast iron force main is nearing the end of its useful life and needs to be replaced. A 12-inch PVC force main runs along Orient Road on the east edge of the redevelopment area, and a 12-inch force main of ductile iron and PVC runs along E Hillsborough Avenue on the south edge of the redevelopment area. The installation dates of the force mains are unknown however, a few observations can be made. The 12-inch force main composed of ductile iron and PVC may have issues with H2S gas corrosion, which is why this force main could be pieced together with both PVC and ductile iron. Ductile iron and PVC force mains have an expected useful life of 50 to 60 years and are assumed to be in fair condition. Only a few gravity mains are located in the redevelopment area, which is mainly comprised of small lift stations and force mains. The only Lift Station owned by the City of Tampa is located on the eastern portion of the area and feeds into the force main along Orient Road. Figure 17 is a map of the existing wastewater infrastructure in this area. Septic Tanks The study area has a mix of sewer and septic systems to treat the wastewater. Existing County data lists a total of 61 tanks, most of them located in the western portion of the redevelopment area. Locations of the septic tanks are shown on the wastewater infrastructure map (Figure 17 ) . Based on the existing available data provided by the County there are no current plans to convert septic to sewer in this study area. The 2018 Hazen and Sawyer Hillsborough County Septic Tank Conversion - Neighborhood Prioritization Report, identifies areas that should be prioritized for septic to sewer conversion. In this report, parcels that already had wastewater service were removed from the study and only parcels that were single family residential were labeled as a priority for conversion. Therefore, the 56th Street Redevelopment Area was not prioritized for conversion and it is unknown at this time if there are plans for future septic to sewer conversion. One location with existing single family residential and septic at Orient Road and Zeimis Drive may be a candidate for septic to sewer conversion.

Water and Wastewater Infrastructure Assessment Findings The Traffic Analysis Zone (TAZ) data and future land use data provided by Hillsborough County for the 56th Street Redevelopment Area shows no increase in population or change in land use from 2015 to 2045. The City of Tampa David L. Tippin WTP has 39 MGD of available treatment capacity and the City of Tampa Howard F. Curren AWWTP has 36 MGD of available treatement capacity, which may support any potential growth if population projections change. This capacity analysis is based on available permitted capacities of the water and wastewater treatment facilities; no hydraulic capacity analysis of water/sewer transmission mains was completed. Based on the available information and understanding of the existing water transmission mains, additional water and fire flow service should be available from the 42” transmission main along Hanna Avenue. Based on the water and wastewater infrastructure assessment completed for the 56th Street Redevelopment Area, potable water is available to all redevelopment project sites identified in Figure 5 of the report. Sewer collection is available for all redevelopment project sites except for the two projects located along E Hanna Ave, and one project along Harney Road, which have septic systems. Further evaluation of the City of Tampa’s water, sewer, and septic systems need to be studied prior to redevelopment. The following action items have been identified for the 56th Street Redevelopment Area: • Coordination between the County and City of Tampa utility departments to identify capacity issues in the potable water and sewer collection/ transmission systems • Study existing potable water hydraulic model to determine pipe capacity and sizing needs of future developments with new water demands • Study existing wastewater collection, transmission, and wastewater treatment plant capacity to determine if the increased wastewater flow will affect the system • Extend sewer collection/transmission system to the redevelopment projects on E Hanna Ave and Harney Road to eliminate septic to sewer system • Provide water and sewer service connections along street areas that are not currently served to promote redevelopment: • Orient Road and N 56th Street areas were identified as areas that the County will need to coordinate water transmission main extensions • 50th Street, E Hanna Avenue, and 56th Street area were identified as areas the County will need to coordinate sewer collection/ transmission system extensions to eliminate septic to sewer systems Water and Wastewater Infrastructure Assessment Findings

Vulnerability Assessment Section 4
Vulnerability Assessment Exposure Analysis This analysis evaluates the exposure of Hillsborough County assets within the redevelopment area. The exposure analysis is the first step in completing a vulnerability assessment identifying potential flood threats and assets exposed to flooding. As part of this analysis, Asset Threat Matrices were developed to identify the flood exposure for the following assets: • County Maintained Roads • Evacuation Routes • Hospitals • Shelters • Schools • Libraries • Public Pump Stations There are no pump stations, libraries, hospitals, or shelters within the 56th Street study area. The County assets within this area are analyzed based on four flood threats: 100-year event, FEMA Flood Zone, Category 1 Hurricane, and Category 3 Hurricane. The 56th Street Redevelopment Area is within the Hillsborough / East Lake Watershed so the SWFWMD Board Certified Hillsborough / East Lake Watershed 100-year floodplain is used for the 100-Year Floodplain analysis. To determine if an asset is exposed to flooding, the flood data is overlayed on top of the asset location. If the flood area intersects the asset footprint, then the asset is considered exposed. It was determined that neither of the Hurricane flood threats exposed any assets within this project area. County Maintained Roads There are 21 County maintained roads identified within the 56th Street Redevelopment Area. Out of all the flood threats evaluated, the 100-Year Event exposed approximately 90% of the County maintained roads. The FEMA Flood Maps were found to expose approximately 24% of County maintained roads exposed. These percentages refer to how many roads were impacted out of the total number of roads, not the total length of roadways submerged. Integrating flood depths is the next step of the vulnerability analysis. The asset threat matrix Table 11 identifies each County maintained road and its exposure to flooding during each flood threat. The results of this analysis were compared to the results of the USF Hillsborough County Community Vulnerability Study. The USF study maps showed there is no exposure in this project area for Category 1 and Category 3 Hurricanes with Intermediate-Low and High SLR. Additionally, the USF maps showed exposure of N 56th Street by the 100-Year Event. The maps for the 100-Year Event and FEMA Flood Map are shown in Figure 18 and Figure 19 .
