Without knowing the ...

Without knowing the specifics, I'd speculate that the existing drainage system and golf course ponds are being tailwater controlled by tidally-influenced groundwater levels. Rainfall events coinciding with high tides are becoming increasingly problematic along the east coast of Florida. Creating additional storage or detention areas, such as wetlands, will really only be beneficial if there is the ability to place them above the groundwater table, otherwise most of the storage will already be filled when the storm occurs. Vaults that are normally dry and isolated from the water table may provide some relief, but may be costly. 

In terms of bid documents, any competent engineering firm that does drainage design can round up the information needed. I don't think the owners need to compile that information. As it appears to be a private organization, their purchasing rules may not require bids. I'd start with their board reaching out to local engineering consultants to see if they can have a few come out and look at the problem and then have them develop proposals to hopefully make things better. I'd proceed incrementally: have an engineer clearly identify the cause; develop several alternative solutions; and then implement the preferred solution.
