Status As Of: June 25, 2009
Final model calibration including review of hydrology and water quality modules is complete. The SIMPLE model
installation files have been made available for trial runs. Final calibration of the water quality module was anticipated to
be completed in late November or early December 2008; however, data reviews noted inconsistencies in the values
reported. Further inspection revealed stormwater samples collected were not flow weighted, therefore they are not
suitable for use to develop EMCs (Event Mean Concentrations) for pollutants of interest. Established literature values for
EMCs were used for model simulations and calibration. Project team members met in early December for model
discussions and reviews. Additional time for final model calibration and testing was needed. Likewise, additional time was
needed to subsequently draft the final project report. Sarasota County requested a no-cost time extension to the
agreement. District staff concurred with the request. Approval of the extension was completed by early January 2009.
The approved amendment extends the contract termination date to June 30, 2009. Additional time may be needed to
sort out the EMCs issues and to process final invoices.
