Contract #SD624AA o Basin and Sub -Basin Boundaries with Acreage's delineated o Basin/Sub-Basin Identification Number • Hydrography • Channel cross sections within major flow ways • Structure Location and Identification Number Q Existing and Future Land Use • USDA-NRCS Soil Type • Wetland delineations (Based for Existing Available Land Use Land Cover Data) ® Corporate Boundaries Inventory of drainage structures and basin network by the Consultant for detailed study reaches shall include the following parameters: • Structure Identification Number Structure Type and Size • Channel Flow Length to Next Structure The existing stormwater management facilities, within each basin, including manmade facilities (i.e., constructed retention and detention areas and conveyances) and natural facilities (i.e., wetlands, waterways, and lakes), will be inventoried from existing permit data by the Consultant and included in the modeling by ECT and the St. Johns River Water Management District. The size of the facility, the size of the contributing watershed and hydrological characteristics will characterize the stotmwater management facilities. Environmental assessment of existing wetland habitat conditions along the canal corridors shall be studied and documented in detail. The potential for recreation, enhancement and preservation or conservation of wetland habitat areas shall be included in the assessment. The created wetland at COUNTY's Wastewater Treatment Facility may be studied as an example. Indicate known presence of any rare, unique, threatened or endangered plant or animal species and provide requirements and recommendations associated with proposed improvements for protecting these species within the Master Plan Area. The report, maps, and inventory shall be completed by the Consultant and submitted to the steering committee by December 31, 2000. Task No. 3 — Modeling of the drainage system for existing and future conditions: 3-A The conversion of the version 3 SWMM model to the most current version of the SWMM model (Visual SWMM model) and all existing available data shall be evaluated by DISTRICT to identify any problems with the model or missing data necessary to the study. Additionally, conflicting data will be identified. Missing or conflicting data will be evaluated to determine the appropriate method of obtaining the needed data or resolving conflicts. Following completion of the model conversion by ECT, a coordination meeting will be scheduled with COUNTY, IRFWCD, and DISTRICT to discuss the model conversion and to obtain input from COUNTY and IRFWCD concerning the modeling.
