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 Palm River 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 Palm River 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 including the criticality of flood depths. 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 68) are a summary of the assessment findings and identification of the highest areas in which to focus to support the Targeted Redevelopment Program goals. A map of the recommended improvements is shown on page 71, Figure 23 . 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 communities identified as pilot areas. One of these pilot areas is the Palm River Redevelopment Area. The Palm River Redevelopment Area, located in central Hillsborough County, is comprised of approximately 6,610 gross acres of land. As shown in Figure 1 , the redevelopment area is bounded by Causeway Boulevard and Selmon Expressway/State Road 618 to the north, Madison Boulevard/ Progress Boulevard to the south, I-75 to the east, and the Port of Tampa/Hillsborough Bay to the west. Key elements within the study area include the freight terminals on Hillsborough Bay and a freight rail line that vertically traverses the study area. Additional key elements of the redevelopment area include the Port of Tampa to the west, multiple new housing developments being constructed, and various manufacturing and warehousing operations located near the port. Project Purpose The purpose of this assessment is to evaluate the current infrastructure in terms of how well the Palm River 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 Palm River 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.

Business and Demographics An estimated 585 businesses are located in the study area that support 7,050 employees, based on 2021 ESRI Business Analyst. The breakdown of businesses by North American Industry Classification System (NAICS) category are shown in Table 2 . Wholesale Trade and Retail Trade make up the largest percent of total businesses in the study area based on percent of total employees with 18.7%, and 14.0%, respectively. These trades involve businesses across the study area including supply and food stores, repair and maintenance shops, and other commercial and personal services. Other significant businesses in the area include construction and engineering services, and warehousing and distribution centers. Many of the businesses are accessed by freight rail and trucks, requiring a large footprint for parking lots and rail right-of-way. The United States Census Bureau tool, OnTheMap, was used to summarize employee inflow and outflow within the study area based on most recently available data (2019). It should be noted that the number of employees vary between the OnTheMap and ERSI projection due to different data sources, time frames and analysis methodologies. According to the OnTheMap application, approximately 63% 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 35% who leave the study area for work, and 2% who live and work in the study area. The Palm River Redevelopment Area has an estimated population of 19,996 people and 7,735 households, based on ESRI 2021 projections. Residential uses are concentrated in the redevelopment area between S 66th Street and S 86th 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 15 years old or younger, 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 uses in the redevelopment area are Heavy Industrial, Light Industrial, Residential, and Mixed Use, shown in Figure 4 . There are portions of the redevelopment area along Causeway Boulevard that are categorized as Office Commercial. There is a small portion at the southwest corner of the redevelopment area that is categorized as Natural Preservation. Currently, there are approximately 2,263 acres of Planned Development (PD) within the redevelopment area. Competitive Sites have also been identified in the redevelopment area. Competitive Sites are defined by the Hillsborough County Economic Development Department’s Competitive Sites Program as locations with the capacity to support targeted office/industrial development. The Program crafts policies and programs to guide public sector engagement and investment to meet economic development objectives in redevelopment areas. 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 square feet 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 Palm River Redevelopment Area, these sites include site development and construction for warehouse and flex workspace uses.

Transportation Assessment Section 2
Transportation Assessment The Palm River Redevelopment Area is generally bounded by state-owned principal and major arterial roadways including US 41, US 301, I-75, Selmon Expressway and Causeway Boulevard (FL 676). Access from I-75 to the study area is limited to only US 301 and Causeway Boulevard. Falkenburg Road and Madison Avenue/Progress Boulevard are also classified as arterial roadways, but are maintained by Hillsborough County with Suburban context classification and provide connection to residences and employment areas internal to the area. 36th Street, Hartford Street, and 78th Street are defined as collector roadways, maintained by Hillsborough County and have Suburban or Urban context classification to provide 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 To measure travel time reliability, Travel Time Index (TTI) data was documented from Iteris Clearguide for 2019. TTI 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 TTI indicates travel times greater than 20% of the free-flow speed travel time in both directions for all study roadways except for US 41 and S 78th Street. Both US 41 and S 78th Street have travel times greater than 10% in the southbound direction. The evening TTI indicates travel times greater than 20% of the free-flow speed travel time in both directions for all study roadways except for S 78th Street and I-75. Both roadways have travel times greater than 10% of free-flow speed travel time in both directions. Trucking and Freight shown in Table 5 and Figure 6 . Travel Time Reliability As defined in the Hillsborough TPO’s 2016 Freight Logistics Zone Strategic Plan, the Palm River 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 truck routes to be reliable from a travel time and pavement condition perspective. Truck routes are shown in Figure 9 with the underlying p.m. peak-hour TTI, and in Figure 10 with the underlying pavement conditions.

Context Classification 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. 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. Context based classification focus on local context and typologies to address use and community needs, connectivity, walkability, placemaking, livability, and community values. The context classifications of County roads in the Palm River Redevelopment Area include Suburban Residential, Suburban Commercial, and Urban General. As indicated in Table 9 , Hartford Street, South 78th Street, Causeway Boulevard, South Falkenburg Road, and Madison Avenue 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 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 or 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. Table 9. Context Classification

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 that could include speed reduction, improved facilities for all modes, and congestion reduction measures: • Falkenburg Road from Progress Boulevard to Selmon Expressway • Hartford Street from US 41 to 70th Street • Madison Avenue from US 41 to 78th Street • 36th Avenue from US 41 to 78th Street • 70th Street from Causeway Boulevard to end • 78th Street from Causeway Boulevard to Madison Avenue • S Falkenberg Road & Causeway Boulevard
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.
• S 78th Street & Causeway Boulevard • Progress Boulevard & S 78th Street • Madison Avenue & US 41 • Madison Avenue & 66th Street • US 301 & Causeway Boulevard • S Falkenberg Road & Causeway Boulevard
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: • Hartford Street from railroad to South 54th Street • 54th Street from Causeway Boulevard to St Paul Street • 66th Street south of Madison Avenue • Santa Fe Road west of railroad The following roadways are identified as serious to failed conditions and are recommended to be considered for reconstruction: • Port Sutton Road west of railroad • Trenton Street west of 51st Street • Towaway Avenue from US 41 South to Sagasta 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 includes the identification of water/sewer service providers, water and wastewater treatment plant permitted capacities, and large water/sewer transmission infrastructure locations. 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, the 2018 City of Tampa Howard F. Curren AWTP Phase 2 Master Plan Report, the 2018 City of Tampa Master Plan Report – Potable Water Master Plan, Florida Department of Environmental Protection (FDEP) permit data, and the 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 Palm River redevelopment area is served by a combination of City of Tampa and Hillsborough County water and wastewater collection and transmission systems. The City of Tampa provides potable water to approximately 75% of the study area, primarily in the western portion, from the David L. Tippin Water Treatment Plant (WTP). Hillsborough County provides water to the remainder of the study area through the South- Central water system which includes the Lithia WTP and the Central Hillsborough WTP. There are 12 interconnects between the City of Tampa and Hillsborough County water systems within the study area. Hillsborough County treats the majority of wastewater from the redevelopment area, but the City of Tampa owns and maintains several force mains on the northern edge of the study boundary. The redevelopment area is served by both the Hillsborough County Falkenburg Advanced Wastewater Treatment Plant and the City of Tampa Howard F. Curren Advanced Wastewater Treatment Plants (AWWTP). Future Land Use/Growth A map showing the future land use of the Palm River redevelopment area is included in Figure 4 . The redevelopment area is comprised mainly of heavy and light industrial land, with some larger areas of regional mixed-use, residential, and urban mixed-use land. Smaller portions of public/quasi- public, natural preservation, and suburban mixed-use land are also located in the study area. Based on the future land use from provided TAZ data, Hillsborough County population projections in the Palm River redevelopment area are expected to have a population increase of 9,978 people between 2015 to 2045. Using the County standard of 300 gallons per day (GPD) water demand per Equivalent Residential Connection (ERC) this population growth is expected to increase the water flows by 2.99 MGD. Using the County standard of 200 GPD of wastewater per ERC this population growth is expected to increase the wastewater flows by approximately 2.00 MGD.

Existing Public Water and Wastewater Infrastructure Water Treatment Plant Capacity
The Palm River redevelopment area is served by the South-Central water system which includes the Lithia WTP and the Central Hillsborough WTP, as well as the City of Tampa’s David L. Tippin WTP. The South-Central potable water system has a permitted capacity of 88.6 million gallons per day (MGD) of flow, as provided by the County. The system’s maximum flow is 68.9 MGD and its available treatment capacity is 19.7 MGD. As reported in the 2018 City of Tampa Master Plan Report – Potable Water Master Plan, the David L. Tippin WTP has a max flow of 120 MGD and an annual average daily flow of 81 MGD. The available potable water production capacity of the facility is 39 MGD for new development. Both the Hillsborough County and City of Tampa potable water production capacity are adequate to support growth in this study area. Wastewater Treatment Plant Capacity The Palm River redevelopment area is served by the Hillsborough County Falkenburg AWWTP and City of Tampa Howard F. Curren AWWTP. The Falkenburg AWWTP has a permitted capacity of 12 MGD, an annual average flow of 10.2 MGD, and a maximum flow of 11.71 MGD, with available annual average flow capacity of 1.8 MGD. As reported in the 2018 City of Tampa Howard F. Curren AWTP Phase 2 Master Plan Report, the Howard F. Curren AWWTP 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 MGD of available annual average flow capacity. See Table 10 below for a summary of the capacity analysis.

Existing Public Water and Wastewater Large Transmission Mains Water The Palm River Redevelopment Area has several water transmission lines within its boundaries including the following: • US Highway 301 S – 36” ductile iron water main (installed 1990/1995) • South 50th Street – 24” cast iron water main (installed 1957) • Madison Avenue, Pendola Point, and 78th Street – 16” ductile iron water mains (installed in 1981, 2001, and 1975, respectively) The ductile iron pipes are within their lifespan of 50 years, but the cast iron piping on South 50th Street is reaching the end of its life expectancy of 80 to 100 years. It is recommended to further evaluate the remaining useful life of the cast iron pipe water main. There are 12 interconnects between the Hillsborough County and the City of Tampa water systems along the north edge and within the study boundary. The interconnects serve as redundancy for the potable water systems and emergency backup. Figure 16 is a map of the existing water distribution infrastructure in this study area. Wastewater The redevelopment area has several wastewater force mains within its boundaries including: • Falkenburg Road – 20” PVC force main south of Causeway, 24” force main north of Causeway (Hillsborough County) • Progress Boulevard – 16” PVC force main (Hillsborough County) • US 301 – 12” ductile iron force main (City of Tampa) • Madison Avenue – 6” PVC force main (Hillsborough County) • CSX track – 8” PVC force main (City of Tampa) According to County GIS records, most of these force mains were installed in the 1990s or later. Ductile iron and PVC pipes have an expected useful life of 50 to 60 years thus these pipes are assumed to be in fair condition and should have adequate remaining useful life. There is a total of 11 lift stations owned by the County and 3 lift stations owned by the City of Tampa within the eastern portion of the study area. There are residential gravity sewer mains that connect to lift stations, which connect to force mains within the eastern half of the study area, but wastewater infrastructure is minimal in the western half of the area. Figure 17 is a map of the existing wastewater infrastructure in this study area.

Septic Tanks According to the Florida Water Management Inventory – Hillsborough County Wastewater Map, the redevelopment area has a mix of sewer and septic systems. Primarily in the western half of the area, wastewater is treated by onsite septic systems. Existing County GIS data has a total of 246 septic systems within the study area and the locations of the septic tanks are shown on Figure 17 . The 2018 Hazen and Sawyer Hillsborough County Septic Tank Conversion – Neighborhood Prioritization Report, the Palm River redevelopment study area falls within group D of potential 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. The County has an estimated total of $17.3M for septic to sewer improvements in an area north of Causeway Boulevard but does not include the Palm River redevelopment area at this time. Based on this assessment of wastewater infrastructure, a location with existing single family residential and septic systems between 54th Street and 84th Street may be a candidate for septic to sewer conversion.
43 Section 3
Water and Wastewater Infrastructure Assessment Findings The Traffic Analysis Zone (TAZ) data and future land use data provided by Hillsborough County for the Palm River redevelopment area shows a 9,978 person increase in population from 2015 to 2045. The estimated increase in potable water demand is 2.99 MGD and the estimated increase in wastewater generation is 2.00 MGD. The South-Central water system has 19.7 MGD of available permit capacity and the David L. Tippin WTP has 39 MGD of available capacity showing adequate production capacity to serve the 2.99 MGD increase in water demand. The Hillsborough County Falkenburg AWWTP has 1.8 MGD of available permit capacity and the City of Tampa Howard F. Curren AWWTP has 36 MGD of available permit capacity. If the majority of the increased wastewater flow is to be routed to Hillsborough County, there may be a treatment capacity issue at the Falkenburg AWWTP to serve the anticipated growth. If no wastewater treatment plant expansions are planned by Hillsborough County at the Falkenburg AWWTP, wastewater would need to be diverted to the City of Tampa or to the Hillsborough County Valrico AWWTP so that the Falkenburg AWWTP does not exceed its available permit capacity. The Hillsborough County Valrico AWWTP has a permitted capacity of 12 MGD, with an annual average flow of 7.25 MGD and a maximum hourly flow of 7.93 MGD. This provides an additional 4.07 MGD wastewater treatment plant permitted capacity for new development or redevelopment. This capacity analysis is based only on the available permitted capacities of the water and wastewater treatment facilities; no hydraulic capacity analysis of water/sewer transmission mains was completed. Based on the water and wastewater infrastructure assessment completed for the Palm River 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 the two projects located along Hartford Street, which have septic systems. Further evaluation of the City’s and County’s water, sewer, and septic systems need to be studied prior to redevelopment. The following action items have been identified for the Palm River 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 Hartford Street to eliminate the septic sewer system • Provide water and sewer service connection along street areas that are not currently served to promote redevelopment: • Hartford Street, 36th Avenue, 70th Street, 78th Street, and US 41/50th street areas were identified as areas the County will need to coordinate sewer collection/transmission system extensions to eliminate septic to sewer systems • 36th Street and 70th Street areas were identified as areas that the County will need to coordinate transmission main extensions Water and Wastewater Infrastructure Assessment Findings
