Drainage System Site Work for Okeechobee High School

This is a request for proposal for drainage system site work. The purpose of this report was to identify problematic areas of drainage, areas Of drainage concerns and potential remedies, conveyance improvements as well as proposed minor recommendations for additional onsite stormwater storage. The high school site, along the east of Highway 441, with sport fields as shown below consists of 50,2 +/- acres. Cunently very minor storage and water quality components are located onsite. Conveyance swales and existing grading are the sole facilities. It is important to note, 2 onsite dry detention areas are onsite, however their size and location are not conducive to either expansion or adding additional flow towards them. These facilities are at the south end of the football field and flow stormwater offsite to the south. See Exhibit A. The agricultural education area on the west of Highway 441, consists of approximately 31.5+/- acres, however the focus of this report will be the 4.0+/- acres along Highway 441 and seen below. During the preparation of this report, high levels of stormwater were encountered and this project area was added to this report with a recommendation for additional storage. See Exhibit B. High School Conveyance Restrictions and Recommendations Restrictions during discussion with staff include grading within buildings, existing elevations of buildings and retaining all sports fields and open areas in as utilizable condition possible. The existing above is also coupled with cost restrictions and would be in order of most efficient for dollars spent.
