7 PONTE VEDRA BLVD CI REPLACEMENT PROJECT DEFINITION TECHNICAL MEMORANDUM Index Number Ponte Vedra Blvd 6 CI WM Replacement PREPARED FOR: JEA Water System Planning PREPARED BY: Joshua M. Brown, E.I. DATE: 3/27/2018 Introduction & Background The purpose of this Technical Memorandum is to define the scope, schedule, and estimated capital cost for the replacement of the existing 6 cast iron (CI) potable pipe along Ponte Vedra Blvd between Pablo Rd and Corona Rd, referred to in this memo as the project. The 6 CI is to be replaced with 8 inner diameter pipe. In addition, the enclosed information is provided for JEA s use in procuring a design consultant to complete the management, engineering design, and permitting of the Project improvements. In sum, the Project, as defined further herein, will replace the entirety of the CI pipe in the area defined above, as it has reached the end of its useful life. Figure 1 shows an overview of the project area and the length of pipe to be replaced is shown. Justification Approximately 9,400 linear feet of 6 CI along the east side Ponte Vedra Blvd between Pablo Rd and Corona Rd was installed in 1997 according to historical records. According to GIS records there are approximately 11 hydrants connected to the existing 6 in line. During hydrant flow tests of these lines it was noted that they were producing extremely low flows along with unusually large drops in residual pressure. These conditions are not favorable for reliable fire protection of the area. Two recent flow tests are detailed in Table 1. Hydrant Location Date/Time Static Residual Flow Ponte Vedra Bv 140 S of Miranda Rd 12/15/17 11:07am Ponte Vedra Bv and Miranda Rd 12/15/17 11:18am Table 1: Two recent fire flow tests along Ponte Vedra Blvd show low hydrant production and large drops in pressure during hydrant flow. In addition to more reliability for the fire protection system; Ponte Vedra s water system experiences regular intervals of lower pressures. This is partially because smaller isolated systems are more sensitive to demand related pressure fluctuations, but also because the Ponte Vedra system still includes lengths of aging cast iron pipe. The replacement of these pipes would very likely have a measurable impact on pressures for the system as a whole. Figure 2 below shows a trend of pressures recorded in August 2017 to JEA s SCADA system for the three potable system gauges that JEA maintains in Ponte Vedra, there are regular occurrences of pressures dropping below 50 psi. It can also be argued from this data that the Ponte Vedra system is more sensitive during times of peak demand. 1

9 PONTE VEDRA BLVD CI REPLACEMENT PROJECT DEFINITION Figure 2: August 2017 trend of pressures from JEA s potable system gauges in the Ponte Vedra grid. These results indicate that the 6 CI length of pipe has likely experienced an accelerated rate of tuberculation decreasing the effective inner diameter of the pipe, therefor inhibiting its functionality. It is recommended to increase the size of the pipe as well to meet expected increases in demand and fire protection. The currently installed hydrants will remain on the new line. Scope Reliability The entire length of 6 CI along Ponte Vedra Blvd between Pablo Rd and Corona Rd is to be replaced by 8 inside diameter pipe. Methodology The methodology is to be determined by the consulting engineer but for the purposes of budgeting is assumed to be pipe bursting. Pipe bursting will limit disruption of private residential property as the pipe to be replaced currently lies under a large number of residential driveways. There are approximately 11 fire protection hydrants connected to the existing 6 CI line, these will need to be connected to the new 8 line as it is being installed. At least two additional laterals will also be installed connecting the new 8 line to the existing 12 water line on the western side of Ponte Vedra Blvd at Pablo Rd as well as Corona Rd Routing and Alignment The new 8 water main will take the place of the existing 6 CI line along the east side of Ponte Vedra Blvd between Pablo Rd and Corona Rd The line is currently capped at Pablo Rd and the new line will be as well, however the new 8 line should also be connected to the 12 water line on the western side of Ponte Vedra Blvd at Pablo Rd The new line will be connected to the 8 water main on Ponte Vedra Blvd at Corona Rd and should also be connected to the 12 water line on the western side of Ponte Vedra Blvd 3

10 Special Crossings PONTE VEDRA BLVD CI REPLACEMENT PROJECT DEFINITION There are no crossings that would specifically require a prescribed installation method, but it should be noted that the layout of the proposed pipe runs under approximately 75 residential driveways as well as the main road that runs through Ponte Vedra Country club. Because of these considerations it is recommended that the installation method be pipe bursting. Land Ownership The proposed work should all occur within existing easements. Permitting An FDEP construction permit will be required for this project. The need for any additional associated permitting should be addressed during the design phase. Any permits determined necessary for construction should be assessed and obtained by the design team. Maintenance of Traffic will likely be needed for this project installation.
