This project is comprised of two components - WCA 2B Flows to Central Lake Belt Storage Area and Central Lake Belt Storage Area (L-30 partial).

The purpose of the first component is to attenuate high stages in WCA 2B and divert excess water primarily to Northeast Shark River Slough and eventually to Central Lake Belt Storage Area via pump station, culverts, canals such as L-33, L-35 and L-37 and conveyance features. A part of this component consists of the improvements to L-37 and L-33 borrow canals (renamed C-500A and C-500B, respectively) to enable excess flow. The Central Lake Belt Storage Area will require the upgrade of the L-30 Borrow Canal and a revision of its purpose. Initially, the L-30 borrow canal would make dry-season deliveries to the South Dade Conveyance System via C&SF L-31N system located south of US-41 (Tamiami Trail). However, it will now be upgraded to convey regional natural system deliveries to the Northeast Shark River Slough while still maintaining its primary purpose in reducing seepage loss from WCA 3B area. As a result, the L-30 canal will be redesignated as the C-501 canal and C-503 canal or the Dade Broward Levee Canal will make deliveries to the South Dade Conveyance system.
