I-4 Infrastructure Assessment

minor service laterals servicing locations within Node Area 2, but there are not any distribution or transmission lines within the boundary. According to County GIS records these water mains are ductile iron and were installed in 1997 (CR 579/Mango Road) and 1988 (Pruett Rd). The County expects these water mains to be in fair condition based on the minimal repair efforts they have had in the area. Similarly, to Node Area 1, the areas not currently serviced by the County are expected to have onsite wells. Similarly, to Node Area 1, Node Area 2 does not have any County wastewater infrastructure within its boundary, and it is expected that this area and a majority of the surrounding area are on septic systems. Adjacent to the southern portion of Node Area 2 there is a 4” PVC force main running south on CR 579/Mango Road constructed in 2000. This force main is servicing a small area and is expected to have little capacity remaining. The primary land use of Node Area 2 is agricultural estate, septic and well systems are typical of large rural areas. Node Area 3 Node Area 3 is the furthest east area in the study boundary, with area to the north and south of I-4. This area does not have any County water infrastructure within its boundary or nearby. This area is expected to have onsite wells, similar to both Node Areas 1 and 2. Node Area 3 has minimal wastewater infrastructure with one force main within it’s boundary, a 6” force main running North/South on Gallagher Road servicing Strawberry Crest High School and Bailey Elementary School. According to County GIS records this 6” FM was constructed with PVC in 2009 and is expected to be in good condition. The remaining areas in Node Area 3 are similar to both Node Areas 1 and 2 and are expected to all be on septic systems. Public Water and Wastewater Existing Capacity Water Treatment Plant Capacity As outlined in the January 2020 Capacity Analysis Report, the Lithia water treatment facility is expected to handle new growth within the County since the Central Hillsborough water treatment plant has hydraulic limitations to provide water to the system. The Lithia Water Treatment Plant will not be able to handle new growth past 2026 in the County without upgrades to the plant. To support new growth in the node areas, the Lithia or Central Hillsborough water treatment plants will need capacity or hydraulic upgrades if growth is expected past 2026. Wastewater Treatment Plant Capacity As outlined in the May 2020 wastewater capacity analysis report, the Valrico AWWTF has the most capacity and is assumed to take the wastewater flow increase in the study boundary. There are currently no capacity issues anticipated unless flow is diverted from another wastewater plant at the County to the Valrico facility. Public Existing Stormwater Infrastructure The purpose of the existing stormwater infrastructure assessment is to define the existing drainage infrastructure supporting the three Node Areas and define known existing flooding issues based on a limited desktop study. The three Node Areas were studied together as a whole. The three areas are primarily rural areas with minimal impervious areas other than roadways to cause major runoff.
