• Running south: a new 12" reuse water distribution main will be installed from Sea Oaks and will run along the east side of SR A -1-A, south along SR A -1-A, approximately 8,594 If to Old Winter Beach Road, where it will connect to a recently constructed 16" reuse main in Old Winter Beach Road • Along the length of the reuse water distribution mains, stub -outs with valves will be located at strategic locations for the future connection and distribution of reuse water to several communities, providing irrigation quality reuse water. c. Construct a 3.0 MG reuse storage tank and a pumping facility. Optional systems that were considered are. Scenario A: Tank and Pump not needed Scenario C - (C-2): 1.607 MGD flow. 1115 gpm min. / 195 ft. pump capacity Scenario D — (D-1): 4.199 MGD flow. 2915 gpm min. / 195 ft. pump capacity Scenario D — (D-2): 1.995 MGD flow. 1385 gpm min. / 195 ft. pump capacity Constructabilitv The reuse transmission and distribution mains co tt5 empl�ated wit is preliminary engineering report and evaluation are proposed along SRA -1-A etween CR 510 and Old Winter Beach Road. Right of way width is limited, and existing roadway andIrray improvements limit the area available to install the reuse mains. Therefore, a detail d evaluation fj he constructability of the reuse main was prepared, and it was determined that ade to ms's available to install the proposed reuse mains along the east side of SR A-1- using the irectio al bore method of pipe installation. This evaluation included: 1. Obtained locates fro all utili ro iders. This is was provided by painting and flagging the location of thet, tail ies a' on th route. 2. Obtained availablebuilts of record from all utility providers. 3. Prepared a detailed rout sriey of SR A -1-A from CR 510 to Old Winter Beach Road. (by a registered land sou eyor). The survey included the location of the `location paint and flags" from utility providers, topography, location of any above ground utilities and other infrastructure. 4. The physical location of existing utility infrastructure on SR A -1-A ROW was obtained. After review of utility as-builts and utility field locates, it was determined that the east side of the ROW appeared to be the least congested and best location for a new reuse main. To confirm, a licensed utility contractor was retained to excavate a 6 ft. deep trench perpendicular to the road every 750 ft. +/- and other strategic locations, from the EOP to the ROW line, along the proposed A -1-A route. The utility contractor and surveyor recorded the location and depth of all utilities encountered with each excavation, and a cross section of every location was drawn depicting the existing grade, location, depth and elevation of each utility. 5. An Engineering base plan (CAD drawing) of existing conditions along the route of A -1-A was prepared, incorporating the information and drawings obtained or created via steps 1-4 above. The base plan was evaluated to determine the best route for the new reuse transmission and distribution mains. The east side of SR A -1-A was confirmed to be the least congested and easiest route to construct the new reuse main. 161 11
