  5. Acme Basin B Discharge ProjectThe Problem with Current Conditions Acme Basin B Phosphorous Discharges Flow-Weighted Mean Concentration, WY02 (May 1, 2001 through April 30, 2002) Source: 2003 Everglades Consolidated Report, Chapter 8B: Everglades Stormwater Program

  6. Acme Basin B Discharge Project Project Purpose Acme Pumps #1 and #2 must be shut down on December 31, 2006 to comply with the Everglades Forever Act. Water in Acme Basin B must be re-routed north through Acme Basin A and discharged into the C-51 canal. Requires: • Improvements to C-1 canal to increase conveyance capacity and connect the C-1 canal to the C-51 Canal • Construction of new pump station AcmePS7 to pump from C-1 canal into C-51 Canal • Construction of detention area in Section 24 for temporary offline storage • Construction of new pump station AcmePS24 to fill the Section 24 detention area

  7. Acme Basin B Discharge Project Project Features S-319 PUMP #4 C-51 CANAL PUMP #3 PUMP #6 Southern Blvd. S-155A NEW PUMP #7 (220 cfs) BASIN A STA-1E C-1 CANAL S-361 PUMP #8 40 SEC 24 NEW PUMP #24 (200 cfs) S-362 BASIN B WCA-1 LOXAHATCHEE NATIONALWILDLIFE REFUGE PUMP #1 PUMP #2

  8. Acme Basin B Discharge Project C-1 Canal Improvements and AcmePS7 • C-1 Canal Improvements • 3 miles of modified section for 67 to 220 cfs conveyance capacity • Two 84” culverts at FPL crossing • Meets DOT setback requirements for Flying Cow Road • Pump Station AcmePS7 • Connects C-1 to C-51 canal • 220 cfs (three 110 cfs pumps) • Diesel • Includes gravity discharge bay

  9. Acme Basin B Discharge Project Section 24 and AcmePS24 • Section 24 • Converts 365 acres of agricultural land to impoundment with upland areas and tree islands • Storage of up to 5 feet of water (1,028 ac-ft) • Two gated culverts (100 cfs each) for inflow/outflow • Pump Station AcmePS24 • Inflow pump station • 200 cfs (three 100 cfs pumps) • Diesel

  10. Section 24 with additional recreational components

  11. Acme Basin B Discharge Project Project Benefits • C-1 canal improvements and pump station AcmePS7 • Allows Basin B water to be conveyed to the C-51 canal and STA-1E • Section 24 and AcmePS24 • Provides temporary offline storage of 1,028 ac-ft of water • Maintains flood protection in Acme Basin B • Reduces phosphorous load to C-51 canal / STA-1E • Potential water supply • Provides a buffer between natural and developed areas • Converts 365 acres of agricultural land to upland and open water habitat • Provides recreational opportunities • Walking trails, overlooks, equestrian trails

  12. Required C-1 Canal modifications are less than BODR Modeling indicates that 220 cfs is not needed along entire length – flow incrementally increases from 67 cfs at Structure #40 to 220 cfs at AcmePS7 Realignment of Flying Cow Road minimized by using curb & gutter, guardrail, and steeper canal slopes Reduces cost AcmePS7 was moved 1,000 ft south from C-51 canal to near FPL crossing Moves pump station away from residences AcmePS7 equipped with gravity discharge bay Reduces cost of operation Pump stations will be diesel not electric To meet District standards Section 24 primary purpose changed from passive wetland to detention area Maintains flood attenuation and level of service locally and in the C-51 Canal Temporary storage provides regional benefits Reduces phosphorus load to C-51 Canal / STA-1E Section 24 seepage canal added Protects against groundwater mounding Acme Basin B Discharge Project Design Modifications After BODR / August 2005 Workshop
