Assists designers and reviewers Presents a consistent level of expertise
Provides meaningful and practical E & SC drawings
“Toolbox” of latest BMPsToolbox of latest BMPs
Clear expectations for DOT designs
S (ERP) d F d l (NPDES) iState (ERP) and Federal (NPDES) permits:Must use BMPs to prevent the downstream discharge of sediment and turbid water
FDEP and FDOT: Manual is the source for BMPs in both permits.

Five separate sections covering different aspects of the Stormwater Pollution Prevention and Erosion Control Plans.
Five appendices that cover specific scenarios and provide inspection forms and typical detail examples.
Section I – General InformationSection II ‐ Developing Effective SWPPPs and
E&SC DrawingsSection III – Erosion Control MethodsSection IV – Sediment Containment SystemsSection V – Temporary Construction Site BMPs

Construction sites in a coastal environment present Construction sites in a coastal environment present unique challenges because of the direct link to sensitive water bodies and the limited available area to implement erosion and sediment control practices.
This Appendix presents technologies available to pp p gdesigners, hydrologists, and construction personnel for mitigating erosion and sedimentation in coastal areas of Florida.
The information provided for each technology i l d includes: A description of the technology.The general purpose(s) of the technology.Considerations for implementation of the
technology in coastal areas. h h h l h ld b ll dWhen the technology should be installed.
Where and when the technology should not be installed. Inspection and maintenance needs

W t l bl i i lWater-soluble anionic polymers
Used ….
to minimize soil erosion
to decrease loss by binding soil particles, especially claysy
as a water treatment additive to remove suspended particles from runoff.

Agencies involved in this Manual recognize the potential of PAMs for preventing erosion and controlling sedimentation

Yes! Yes!
Practices have not kept pace with developments
Wrong BMPs used – hay bales and silt fenceNew BMPs not being usedPAM “Cookie cutter projects”

Training for the Manual
References the Manual as the source for erosion prevention and sediment control materials and methods for contractors.
Requires the contractor to develop their own site specific sediment and erosion control plan as part of the SWPPPsediment and erosion control plan as part of the SWPPP.
Establishes performance standards for the design, implementation and maintenance of the contractor’s plan.

The contractor has to be involved in a site specific E&SC plan since they know how they want to build the job.End job site “discussions” over design versus
implementation in the event of a failureimplementation in the event of a failureProvide the contracting industry with the best
“toolbox” of materials and methods available to erosion and sediment control
Developed by the UCF Stormwater Management Developed by the UCF Stormwater Management Academy in conjunction with
HydroDynamics Inc.Applied Polymer Systems
Course will consist of three days of instruction ycentered on problem solving followed by a comprehensive final exam.
Tentatively, will be taught at UCF.
