About this file
This document is a Basin Data and Calculations report for the Jetty Park Stormwater project, prepared by engineer Cydney Sims in January 2021 for the Canaveral Port Authority. The report details stormwater management calculations for a development site, specifically focusing on post-development basin data, treatment volume requirements, and storage calculations for multiple basins (Basin01, Basin02, and Basin05). The technical document provides comprehensive hydrological measurements, including area breakdowns of impervious (3.18 acres) and pervious (5.39 acres) surfaces, totaling 8.57 acres.
The calculations demonstrate that the project meets and slightly exceeds required treatment volume specifications. The total required treatment volume is 25,755 cubic feet, while the total provided treatment volume is 25,903 cubic feet. The calculations include detailed measurements at different elevations (6.00 feet and 5.00 feet), with specific computations for runoff volumes from total and impervious areas. The document shows meticulous engineering analysis of stormwater management strategies, ensuring appropriate water treatment and volume management for the Jetty Park development site.

Treatment Volume:
1) Volume from 0.5 inch of runoff from total area
(0.5 in.)(total area)(43,560 sf/ac) = 15,555 cu. ft.
12 in/ft
2) Volume from 1.25 inches of runoff from impervious area
(1.25 in.)(imperv. area)(43,560 sf/ac) = 14,429 cu. ft.
12 in/ft
3) Therefore, greater volume = 15,555 cu. ft.
Total Required Treatment Volume Basin01 and Basin05 = 15,555 cu. ft.
Total Required Treatment Volume Basin02 = 10,200 cu. ft.
Total Required Treatment Volume = 25,755 cu. ft.
Total Provided Treatment Volume = 25,903 cu. ft.
