Start with the receiving system

Ask how water reaches, moves through and leaves the site, and what information is needed to evaluate the proposed change. Existing grades, groundwater observations, surrounding drainage and discharge rights may all become questions for investigation. SFWMD describes environmental-resource permitting as addressing flooding, stormwater pollution, wetlands and surface waters. That overview identifies relevant concerns; it does not establish which permit, exemption or design is appropriate for a particular parcel.

Test the land budget

Consider a hypothetical layout that allocates almost every usable corner to buildings and parking. Engineering review may identify a need for treatment or storage space, revised grades or another drainage solution. The business issue is not simply adding a line item called pond. Ask whether the revised concept changes building area, circulation, earthwork or off-site scope. Do not assume an underground solution is available, approvable or less costly without site-specific design and pricing.

Include the operating obligation

Ask who will own, inspect and maintain the completed system and how that responsibility enters the operating plan. Coordinate drainage easements and off-site rights with counsel rather than treating a drawn discharge arrow as permission. Request the applicable local and water-management review pathway from the relevant professionals. Update the layout, estimate and schedule together when findings change. A feasible drainage concept needs engineering and appropriate review; a public explainer cannot supply calculations, certify flood protection or promise that the intended site yield will survive.
