Hydraulic & Hydrologic Modeling and <br />Water Resources Engineering <br />SOUTH FLORIDA WATER MANAGEMENT DISTRICT <br />IMMOKALEE STORMWATER MASTER PLAN <br />(2004 -2005) <br />(a- <br />Ross Engineering, Inc. <br />17670 NW 78th Ave <br />Suite 214 <br />Miami, Fl. 33015 <br />Phone: 786.468.8304 <br />Fax: 305.392.1019 <br />owner/Contact Information: <br />South Florida Water Management District BCB Office <br />Max Guerra, PhD, P.E., Project Manager <br />2640 Golden Gate Parkway 3205, Naples, FL 34105 <br />Tel. 239 - 263 -7615 <br />Completion Date: <br />2005 <br />Project Description: <br />Ross Engineering Scope of work as follows: <br />• Assisted in the data collection effort that included Big Cypress <br />Basin (BCB) gauges, recently flown Lidar Data used in DTM, survey <br />of culverts, canal, ditch and wetland cross sections, DB -Hydro <br />data extraction and field testing. <br />• Assisted in the build -out of the XP -SWMM model that consisted of <br />33 hydrologic sub - basins spanning over 15 square miles urban and <br />rural area. Hydraulic links included canals, culverts, ditches and <br />wetland flowways. <br />• Continuous simulation modeling of long term rainfall as part of the <br />calibration and verification of the model with simulated <br />groundwater interaction with surface water facilities. <br />• Event mean concentration water quality modeling using Harvey <br />Harper method of estimating pollutant loadings for P, TN, Ecoli, TSS <br />and NH4. Water Quality modeling was calibrated using District <br />gauge information and was verified by field testing performed <br />after a summer 2004 storm event. <br />Reports that were submitted to the District: (1) water quality <br />assessment report, (2) engineering evaluation, (3) environmental <br />evaluation, (4) flood control improvement plan, (5) wetland <br />flowway improvement plan and (6) water quality improvement <br />plan. <br />• Alternative Design Models for 6 options included both water <br />quantity and quality comparisons to the existing conditions. <br />Improvements included 2 impoundments, culvert upgrades, <br />dredging and widening of a canal, proposed collection systems <br />and exfiltration trenches. <br />Conceptual design of improvements with conceptual ERP permit, <br />easement identification, and funding method analysis. <br />Key Staff: <br />Robert J.
