performed by the City, which concluded that substantial upgrades were required to the existing storm sewer collection and conveyance system. Mr. Flick provided oversight of the plans preparation and closely coordinated with the City in preparing the SJRWMD permit application. To facilitate an early construction start, the project was divided into two separate projects: Carnation Road Drainage Improvements and Raines Vikings Way Drainage Improvements. Allen Ditch Improvements Jacksonville. Florida Mr. Flick worked on maintenance improvements on this project. The existing ditch collected and conveyed runoff from a 67 -acre watershed and residents at the upstream end of the ditch had been experiencing localized Flooding. Based upon a detailed field reconnaissance, coupled with hydraulic modeling, it was determined that maintenance rather than reconstruction was the most cost effective solution. Plans were prepared that proposed removing accumulated sediment, stabilizing selected segments of stream bank with sod, rebuilding other segments of ditch bank and stabilizing them with erosion control blankets, and adding rubble rip rap as scour protection at selected locations. Old Middleburg Road Redesign Project Jacksonville. Florida Mr. Flick was in charge of redesigning Old Middleburg Road, an urban roadway project. Design involved upgrading an existing rural roadway to three -lane curb and gutter urban roadway section with a continuous center turn lane. Design included an extensive storm sewer pipe network (enclosed drainage) system and two wet detention ponds. The design included an analysis of two watersheds: 318 acres and 282 acres in size. The analysis of the 282 - acre watershed included a channel routing computer model that served three functions: it established City of Sunny Isles Beach 37 Continuing Professioncl Servic_-s for engineering RFallo. 14 -07 -02 P.ugusr 12, 2014 the water surface profile of the stream (tailwater elevation) for 10- year and 25 -year storm events; it verified that a section of improved channel was properly sized (i.e., of adequate cross - section); and it designed two box culverts.to their optimum (most economical) size by allowing multiple "what if' runs of round, oval, arch and box culverts of varying sizes. Storm water permits were secured from St. Johns River Water Management District and Dredge /Fill permits were secured from the Florida Department of Environmental Protection. HCA Oakhill Hospital Brooksville, Florida Mr. Flick worked on the primary civil engineering /site -work elements of this project, which involved the addition of a 432 car employee parking lot and relocation of the existing helistop. The parking area covered 8.57 acres and storm water attenuation and treatment required the construction of a dry retention pond, 200 feet long, 150 feet wide and 6 feet deep. The pond was designed to contain the increased runoff resulting from the 100 year, 24 hour storm event. Water quality was achieved thorough percolation into the bottom of the pond. The storm water design required a determination that the project was surrounded by a closed drainage basin and an analysis of its 190 - acre watershed. A surface water management permit was secured from the Southwest Florida Water Management District. C
