SFWMD Expedited Construction
On October 14, 2004, in the presence of the USACE, Department of Interior, Council on Environmental Quality and other state, local and federal partners, the SFWMD entered into an agreement to expedite implementing portions of eight critical CERP projects, including Biscayne BCW
SFWMD has completed 100% Design Plans for the expedited portions of the Deering, Cutler Flowway and L-31E project components
SFWMD has received all required permits for the expedited portions of the Deering and L-31E Flowway components
SFWMD has completed 100% of the construction for the expedited portion of the L-31E project component (four culverts)
SFWMD expedited construction of a 500-foot extension of the C-100A Spur Canal
SFWMD expedited construction of a 100-cubic feet per second (CFS) pump station (S-700) to withdraw water from C-100A Spur Canal
SFWMD expedited installation of 538 linear feet of 60” pipe downstream of the pump station
SFWMD expedited construction of a spreader structure for discharges to the coastal wetlands located within the Deering Estate
Deering Estate
SFWMD expedited construction of a 400-CFS pump station (S-701) on the C-1 Canal
SFWMD expedited construction of a 1.3-mile-long lined conveyance canal to deliver water from the pump station to a proposed spreader
SFWMD expedited installation of box culverts under SW 97 Ave, SW 87 Ave, and L-31E
SFWMD expedited construction of a two-mile-long spreader canal
USACE to construct remaining portions of spreader canal and plug 2,500 LF of remnant mosquito ditches
Cutler Flowway
L-31E Flowway
SFWMD expedited installation of four flap-gated culverts (S-23A, S-23B, S-23C, & S-23D) to discharge from L-31E to saltwater wetlands East of L-31E

USACE to construct a 100-CFS pump station (S-705) on L-31E to discharge south to L-31E
USACE to construct a 40-CFS pump station (S-709) to discharge from C-103 north to L-31E, and install an inverted siphon (S-707) at Military Canal to isolate it from L-31E
USACE to install six remaining flap-gated culverts (S-706A, S-706B, S-706C, S-708, S-712A, and 712B) to discharge from L-31E to saltwater wetlands
USACE to construct a 40-CFS pump station (S-711) and spreader canal (C-711) to deliver water from C-103 to freshwater wetlands south of C-103
USACE to construct 40-CFS pump station (S-710) to deliver water from C-103 to freshwater wetlands south of C-103, via spreader structure
L-31 E Flowway (Cont.)

Federal CERP Project History and Status
July 2002 – Initiated planning effort
January 2008 – USACE Headquarters approves incremental PIRs, with Alternative O - Phase I as the Tentatively Selected Plan (TSP) for PIR-1
May 2009 – Draft PIR for the TSP was published
Final PIR is currently waiting resolution of a policy issue regarding agrochemical cost-sharing
Federal CERP Project Next Steps
Establish Agrochemical Policy Hold Civil Works Review Board Briefing Revise Final PIR per Coastal Wetlands Review Board
(CWRB) Comments Transmit and Publish Draft Final PIR Respond to Public and Agency Comments File Final PIR Submit Chief’s Report OMB Review Record of Decision Rulemaking for Protection of Water Project Partnership Agreement Congressional Appropriations
