PROJECT DESCRIPTION / SCOPE OF WORK:
Performed data Collection, Existing Conditions
continuous simulation modeling, calibration of 5, 10,25 and 100 year storm
events, Alternatives Modeling and Analysis, Alternative Designs, Conceptual
design and permitting. Project was completed in February 2006. Project covered
25 square miles of coverage area with the Turnpike as the western boundary,
SR836 (Dolphin Expressway) as the southern boundary, Okeechobee industrial area
as the northern boundary and SR826 (Palmetto Expressway) as the eastern boundary
condition.
The objectives of this project were to develop a SWMP to accomplish the
following goals:
1. Analyze the Citys SWMP system and identify deficiencies
2. Propose improvements and develop a Capital Improvement Plan
3. Develop a plan to address Community Rating System (CRS) items
Our team developed a hydrologic and hydraulic (H&H) computer model (SWMM) to
simulate the existing system and develop improvements. We performed the
following tasks to accomplish the stated goals above.
This phased approach was performed on the following itemized tasks:
Phase 1:
Collected and Developed Existing
Information
1. Coordinated with DERM to collect the existing models and information from
reports currently being developed by other consultants including Earth Tech for
the C-6 Basin and PBSJ for the C-4 Basin.
2. Collected available information on the existing stormwater system from the
City, DERM, and FDOT.
3. Collected Hydrologic data using the SFWMD DBHYDRO Database and the USGS GIS
Database.
4. Developed a 3-D terrain model from LIDAR data and Hydrologic Information from
that model.
Phase 2:
System Evaluation and Capital
Improvement Plan
1. Constructed a Hydrologic and Hydraulic Model (Numerical Model) using SWMM.
2. Simulated the Existing Conditions utilizing boundary conditions from the C-4
and C-6 canals (DERM models).
3. Identified Deficiencies with Existing Conditions.
4. Proposed Improvements in the problem areas that were discovered with Existing
Conditions modeling and field verification with City Public Works staff.
5. Modeled Alternative design improvements including control structure
discharges to canals, culvert upgrades, proposed collection systems and
exfiltration trenches.
6. Developed a Capital Improvement Plan
