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 North Airport Redevelopment Area. The purpose of the Infrastructure Assessment is to evaluate how well the current transportation, utility, and stormwater infrastructure will support infill redevelopment, redevelopment, and economic development in the North Airport Redevelopment Area, consistent with the Targeted Redevelopment Program goals. This Infrastructure Assessment includes a Transportation Assessment (page 13) 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 34) 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 42) 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 52) 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 55, Figure 22. 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, Tampa International Airport, 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 North Airport Redevelopment Area. The North Airport Redevelopment Area, located in central Hillsborough County north of the Tampa International Airport, is comprised of approximately 1,426 gross acres of land. As shown in Figure 1 , the redevelopment area is bounded by Linebaugh Avenue to the north, Hillsborough Avenue/State Road 580 to the south, Veteran’s Expressway to the west, and the Woodland Center business park to the east. Freight rail lines traverse the north and east sides of the redevelopment area. The redevelopment area also borders the Tampa International Airport, as shown in Figure 1 . Therefore, the expansion of Tampa International Airport will impact the redevelopment area and 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 North Airport 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 North Airport 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 redevelopment area is bounded by W Linebaugh Avenue to the north, W Hillsborough Avenue/State Road 580 to the south, Veteran’s Expressway to the west, and Woodland Center business park to the east Existing Land Use The existing land uses within the redevelopment area are primarily non-residential. As shown in Figure 3 , a large portion of the existing land uses include industrial, commercial, public/quasi-public/institutions, and vacant land, as well as some single-family residential uses dispersed throughout. Community Facilities In the North Airport Redevelopment Area there are community facilities that include a school and an emergency service facility which are identified in Figure 3 . There are no parks in the redevelopment area. There is one park, West Park, located just outside the redevelopment area along the east boundary. The one elementary school located in the redevelopment area is Crestwood Elementary which is located off N Manhattan Avenue. There is also a middle school located just outside the redevelopment area boundary, Pierce Middle School. There are other nearby schools that are located outside the redevelopment area including Leto High School, Alexander Elementary, Morgan Woods Elementary, Webb Middle School, Town and Country Elementary. Table 1 shows existing and projected school capacities to the 2024-2025 school year of Crestwood Elementary.

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, timeframes and analysis methodologies. According to the OnTheMap application, approximately 99% of the labor market (employees in the area or residents in the area) comes from outside of the study area. The remaining labor market (1%) includes those who leave the study area for work, and who live and work in the study area. The North Airport Redevelopment Area has an estimated population of 129 people and 59 households, based on ESRI 2021 projections. Residential uses are located on the edge of the redevelopment area including single-family homes south of W Linebaugh Avenue and east of Veteran’s Expressway. Population and employmeny statistics are included in Table 3 . Vulnerable populations in the redevelopment area include those 65 years old or older, which make up a higher percentage of the study area population compared to that of Hillsborough County. In addition, the households with an income less than $25,000 represent a vulnerable population, while the median household income in the study area is greater than the County’s median household income, representing a less vulnerable population. A comparison of socioeconomic statistics for the redevelopment area and Hillsborough County is provided in Table 4 . Table 3. Employment and Population Statistics

Future Land Use and Planned Development The primary future land use in the redevelopment area is identified as Light Industrial. There is a small portion of the redevelopment area that is categorized as office commercial, community mixed-use, and residential. There is a limited amount of residential land in the redevelopment area and the Market Study completed for the area in 2017 suggested limited residential growth is anticipated. The Market Study noted there is already a diverse mix of workplace uses including a significant amount of office use and warehouse space as well as four hotels. The Market Study noted the market strengths for this area include the central location in the region, regional highway access, proximity to the Westshore business district, and proximity to the airport. Due to allowable height restrictions for buildings adjacent to the airport, there is a possibility of impacts to potential redevelopment in the southern portion along W Hillsborough Avenue and W Knox Street. Additionally, the Market Study included discussions with CSX representatives. The discussions revealed that there are several existing railroad tracks and spurs in the North Airport Redevelopment Area are not owned or maintained by CSX. Currently, there are approximately 395 acres of Planned Development (PD) within the redevelopment area. The planned developments may include a mixture of uses including residential units, office, and commercial opportunities. PD and competitive sites in the area include two competitive sites available for lease, two planned out competitive sites, and two competitive sites with available land that are zoned for industrial uses. There are seven competitive sites identified in the North Airport Redevelopment Area. The Competitive Sites Program identifies locations with the capacity to support targeted 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 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 North Airport Redevelopment Area, these sites include site development and construction for manufacturing and logistics uses.

Transportation Assessment The North Airport Redevelopment Area is generally bounded by state owned principal arterial roadways including Veterans Expressway to the west and Hillsborough Avenue to the south, County owned major arterial Linebaugh Avenue, and a CSX rail line to the east. Access into the study area is provided by major arterials including Waters Avenue, Sligh Avenue, and Anderson Road. These roadways provide access to employment areas for vehicles including trucks, but present barriers for vulnerable users like pedestrians and cyclists. Benjamin Road is defined as a collector roadway and is also a designated truck route. The majority of the roadways within the study area have Suburban Commercial 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. Roadway V/C Ratios Roadway Limits Peak V/C AADT

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 TTI, Figure 7 , indicates travel times greater than 30% of the free-flow speed travel time for both directions of W Sligh Avenue. Additionally, in the morning the northbound traffic along Benjamin Road and the southbound traffic along Anderson Road, Hoover Boulevard, and Henderson Road exceed the 30% free-flow speed travel time. The evening TTI, Figure 8 , indicates travel times greater than 30% of the free-flow speed travel time on both directions of W Waters Avenue, Hoover Boulevard, W Sligh Avenue, and the northbound direction along Henderson Road, Anderson Road, and Benjamin Road as well as the eastbound direction of W Hillsborough Avenue. The patterns suggest variability in travel time during peak periods for commuting traffic utilizing the northbound and southbound roads within the redevelopment area.

Trucking and Freight As defined in the Hillsborough TPO’s 2016 Freight Logistics Zone Strategic Plan, the North Airport Redevelopment Area is within a logistics cluster with heavy freight activity. As a result of the industrial uses and freight-oriented businesses, several truck routes and rail lines connect to and serve the redevelopment area. To better serve industrial and freight-oriented uses, it is important for the identified 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 22. 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 (Drew Spur) in the North Airport Redevelopment Area. This spur has low utilization compared to the activity countywide which may be attributed to the termini within the redevelopment area. 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 The 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 27% of the total linear feet of roadway (143,732 ft) in the redevelopment area has a PCI score of 55 or higher. 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 Sligh Avenue from Benjamin Road to Manhattan Road, Benjamin Road from Hillsborough Avenue to Waters Avenue, and minor local streets connecting from Benjamin 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 W Linebaugh Avenue, W Waters Avenue, and Anderson Road. There are also fragmented portions of the sidewalk located along Sligh Avenue, Benjamin Road, and local roads throughout the redevelopment area ( Figure 12 ). Bicycle facilities are also present in the redevelopment area. Bike lanes are available on W Linebaugh Avenue, W Waters Avenue, W Hillsborough Avenue, Hoover Boulevard, and Anderson Road. Unfunded multimodal improvements include the Kirby Canal Trail which is proposed to follow the canal through the redevelopment area and connect to the Town N Country Greenway. HART provides transit service in the redevelopment area via Route 16 on Waters Avenue and Route 34 on E Hillsborough Avenue. Along these routes, the stops at the intersection of Waters Avenue & Comfort Suites and Waters Avenue & Woodland Corporate Boulevard have the highest daily average ridership activity in the redevelopment area ( Figure 13 ). Funded transit improvements identified in HART Transit Development Plan (TDP) in the redevelopment area include 15-minute frequency enhancements for Route 34 and the addition of Sunday service for Route 16. A new on-demand service area for HART’s HyperLINK service is also identified as a funded TDP improvement in the redevelopment area.

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 County’s 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 North Airport Redevelopment Area include Suburban Residential, Suburban Commercial, Suburban Town, and Urban General. As indicated in Table 9 , all of the study roadways currently have a posted speed that is greater than the target speed for their respective context classifications. It is recommended to implement speed management techniques 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. Table 9. Context Classifications

Water and Wastewater 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: Transportation Infrastructure Assessment Findings
• Anderson Road from Linebaugh Avenue to Sligh Avenue • Benjamin Road from Waters Avenue to Hillsborough Avenue • Hoover Road from Hillsborough Avenue to Sligh Avenue • Linebaugh Avenue from Veterans Expressway to Mullis City Way • Manhattan Avenue from Waters Avenue to Broad Street • Sligh Avenue from Benjamin Road to railroad crossing • Waters Avenue from Veterans Expressway to Manhattan Avenue • Hillsborough Avenue from Veterans Expressway to Hoover Road
Intersection safety improvements are recommended at the following intersections based on a pat-tern 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.
• Linebaugh Avenue & Anderson Road • Anderson Road & W Waters Avenue • Hoover Boulevard/Anderson Road & Sligh Avenue • W Waters Avenue & N Manhattan Avenue
Based on the pavement condition index of County maintained roadways in the study area, the fol-lowing roadways have poor to very poor pavement condition and are recommended to be consid-ered for major rehabilitation: • Local Streets – Johns Road, Hanna Avenue, Knollwood Street, Knox Street, Idlewild Avenue, Clifton Street, Hangar Court, Conaty Drive, Benjamin Center Drive, Pioneer Park Boulevard, Turnmor Drive, Ann Ballard Road, Sunstate Street, and North Trask Street The following roadways are identified as serious to failed conditions and are recommended to be considered for reconstruction: • South of Sligh Avenue, Johns Road from Thompson Center Court to Sligh Avenue 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 identifying the water/sewer service provider, water and wastewater treatment plant permitted capacities, and locations of large water/sewer transmission infrastructure. 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 North Airport 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 manages approximately 75% of the water mains in the study area, with Hillsborough County providing water to the northern portion of the area (around 25% of the service area). The study area is served by the Hillsborough County Northwest water system, which includes the Fawn Ridge Water Treatment Plant (WTP), the Lake Park WTP, and the City of Tampa David L. Tippin WTP. There is one interconnect between the City of Tampa and Hillsborough County water systems within the study boundary. Hillsborough County provides all the wastewater collection services to the area. Based on the available GIS data, the wastewater flows are treated by the County owned Northwest Regional Water Reclamation Facility (WRF). Future Land Use/Growth A map showing the future land use of the North Airport redevelopment area is included in this report, see Figure 5 . The primary land use is light industrial, with larger areas of urban mixed use, office commercial, and public/quasi- public. The study area also includes small portions of residential, heavy industrial, and community mixed use land. Based on the future land use from the provided TAZ data, Hillsborough County population projections in the North Airport redevelopment area are expected to have a population increase of 440 people from 2015 to 2045. Using the Hillsborough County standard of 300 gallons per day (GPD) water demand per Equivalent Residential Connection (ERC), this population growth is estimated to increase the water flows by approximately 0.13 million gallons per day (MGD). Using the County standard of 200 GPD of wastewater per ERC, this population growth is estimated to increase the wastewater flows by approximately 0.09 MGD.

Existing Public Water and Wastewater Capacity Water Treatment Plant Capacity
The David L. Tippin WTP, managed by the City of Tampa, serves the majority of the redevelopment area. As reported in the 2018 City of Tampa Master Plan Report – Potable Water Master Plan, the treatment plant has a max flow of 120 million gallons per day (MGD) and an annual average daily flow of 81 MGD. The City of Tampa water production capacity at the David L. Tippin WTP has adequate production capacity to serve the growth of this redevelopment area. The northern portion of the redevelopment area is served by Hillsborough County’s Northwest water system. This potable water system has a permitted capacity of 56 MGD of flow and a maximum flow is 30.3 MGD, as received from the County. The available Hillsborough County potable water production capacity at the Northwest system is 25.7 MGD for new development or redevelopment if needed. The water main interconnect between Hillsborough County and City of Tampa also serves as a redundancy and emergency backup for the potable water system in the event of an emergency. Wastewater Treatment Plant Capacity The North Airport redevelopment area wastewater is treated by the Hillsborough County Northwest Regional WRF, all sewer infrastructure is owned and maintained by Hillsborough County. This treatment plant has a permitted capacity of 30 MGD, with an annual average flow of 17.05 MGD and a maximum flow of 19.34 MGD, as provided by the County. This leaves 12.95 MGD of available wastewater treatment plant capacity (annual average flow) for new development or redevelopment. See Table 10 below for a summary of the capacity analysis. Table 10.

Existing Public Water and Wastewater Large Transmission Lines Water The North Airport Redevelopment Area has several water transmission lines within its boundaries including the following: • Bejamin Road - 16” ductile iron water main (City of Tampa, installed 1979) • Henderson Road - 16” ductile iron water main (Hillsborough County, installed 1982)
• Sligh Avenue - 24” ductile iron water main (City of Tampa, installed 1989) • Waters Avenue - 20” ductile iron water main (City of Tampa, installed 1999)
Ductile iron pipe has a service life expectancy of 50 or more years, these mains should still be in fair condition and should have adequate remaining useful life. There is one interconnect between the Hillsborough County and City of Tampa water systems within the area boundary providing an emergency backup for the potable water system in the event of an emergency. Figure 16 is a map of the existing water distribution infrastructure in this area. Wastewater The redevelopment area has several Hillsborough County owned wastewater force mains within its boundaries including: • Waters Avenue - 24” ductile iron force main (Hillsborough County, installed 1989) • Hoover Boulevard/Anderson Road - 6” PVC force main (Hillsborough County, installed 1998) • Linebaugh Avenue - 8” PVC force main (Hillsborough County, installed 2000) Ductile iron and PVC pipes have an expected useful life of 50 to 60 years and are expected to be in fair condition with adequate remaining useful life. There is a small amount of gravity main and a total of 9 lift stations within the study boundary that make up the wastewater collection system. Figure 17 is a map of the existing wastewater infrastructure in this area. Septic Tanks According to the Florida Water Management Inventory – Hillsborough County Wastewater Map, there is a mix of septic and sewer systems in the area. Developments along Benjamin Road, Pioneer Park Blvd, Crenshaw Street, and Anderson Road are supported by a total of 101 septic systems. Locations of the septic tanks are shown on the wastewater infrastructure map ( Figure 17 ). In the 2018 Hazen and Sawyer Hillsborough County Septic Tank Conversion-Neighborhood Prioritization Report, the North Airport redevelopment study area falls within Town N’ Country group B 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 a total of $39.4M for septic to sewer improvements in Town ‘N Country group B but does not include the North Airport Redevelopment Area at this time. Based on this assessment of the wastewater infrastructure, one location with existing single family residential and septic systems along Benjamin Road 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 North Airport redevelopment area shows a 440 person increase in population from 2015 to 2045. The Hillsborough County Northwest water system currently has 25.7 MGD of available permit capacity and the City of Tampa David L. Tippin WTP has 39 MGD of available permit capacity to support the anticipated 0.13 MGD estimated potable water demand increase. Although both City of Tampa and Hillsborough County provide potable water, Hillsborough County owns and maintains all the public sewer infrastructure. The Hillsborough County Northwest Regional WRF currently has 12.95 MGD of available permit capacity to support the anticipated 0.09 MGD increase in wastewater flow if needed. 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 water and wastewater infrastructure assessment completed for the North Airport Redevelopment Area, potable water is available to all redevelopment projects identified in Figure 5 of the report except for the two sites along Citrus Park Lake that will need water transmission main extensions. Sewer collection is available for all redevelopment project sites except the two projects along Anderson Road and the project on Johns Road, which have septic systems. Further evaluation of the County’s and City of Tampa’s potable water, sewer, and septic systems need to be studied prior redevelopment. The following action items have been identified for the North Airport 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 along Anderson Road and Johns Road to eliminate the septic sewer system • Extend potable water transmission mains to the redevelopment projects along Citrus Park Lake • Provide water and sewer service connection along street areas that are not currently served to promote redevelopment: • Hoover Blvd area was identified as an area that the County will need to coordinate water transmission main extension • Anderson Road and Benjamin Road were areas 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
