Structural Projects

	CSI is providing multidisciplinary consulting design services to the SJRWMD. The task order for the E-1 structure consisted of the development of plans and specifications for construction of this water control structure, as part of the Sunnyhill Restoration Project. E-1 Structure is a single box rectangular reinforced concrete culvert with headwalls, wingwalls and an outflow spillway. The culvert has approximate dimensions of 10 (W) x 6 (H) x 60 (L) feet and crosses the existing U.S. Army Corps of Engineers (USACE) levee L-231, discharging water into the C-231 canal. The Sunnyhill Restoration Project, of which E-1 Structure is the upstream-most component, involves the restoration of the historic Ocklawaha River basin and includes several water control structures such as box culverts, circular culverts, levee embankments, impoundments, borrow pits and other minor features. The E-1 project comprised the replacement of the existing structure, consisting of two corrugated metal pipes with risers utilized as means to control water flow. The pipes were highly corroded, with one in such a detrimental state that it had collapsed and caused a sinkhole within the L-231 levee. While the structure owner and operator is the SJRWMD, the levee is maintained by the USACE and is used as both a flood control and vehicular traffic embankment. The levee provides access to this remote area to maintenance crews, construction crews, firefighting personnel, etc. Therefore, it was of utmost importance that the embankment’s overall integrity and functionality was not jeopardized. Considering the above, the SJRWMD tasked CSI to design a new robust and resilient structure to replace the existing pipes, locating the new structure approximately 40 ft south as replacement at the same location was not feasible.
