A Stormwater Master Plan was prepared for the 900-acre main campus at the University of South Florida. The project involved data collection, water quantity modeling, alternative analysis, conveyance system modeling, construction plans and permitting. Advanced Interconnect Pond Routing (adICPR) was used to model the system. Modret and Ponds was used to perform pond recovery analysis. The master plan involved the construction of a cascading lake system which would provide the necessary water quality treatment volume, attenuate the 25-year/24-hour storm event and pre-post the volume for the 100-year/24-hour storm. The volume criteria was due to the location of the campus in a land locked watershed. The plan will allow the University to plan and construct master treatment and attenuation facilities so that future building and parking facilities will not be delayed by permitting plus eliminating the need for individual building-by-building stormwater ponds. This is the first such planning effort for stormwater management for a major university in Florida and may well become a model for other campuses.

Phase I construction was the first design phase to implement this master plan and involve the following design elements:

• Construct one wet retention pond (recovered by exfiltration).
  
• Construct one wet detention pond.
  
• Construct 1,100 LF large diameter (5 to 7-foot) culvert in an urbanized environment.
  
• Construct primary outfall control structures.

DRMP was contracted to complete Phase I upon successful completion and conceptual permitting for the Stormwater Master Plan. For Phase I the tasks included:

• Prepare construction plans.
  
• Obtain SWFWMD, ACOE and FDEP Permits.
  
• Prepare design specifications.
  
• Bidding assistance.
  
• Construction services and shop drawing review.
