Drainage

PGA was founded by two drainage engineers and excellence in the discipline is engrained in our firm’s identity. We pride ourselves on our innovative approach to projects that often lead to significant savings for the client. Our persistence to achieve excellence has allowed our team to become extremely adept at handling every aspect of drainage design. We excel at surface water management and stormwater management design, including the use of ICPR 4. We stay on the cutting edge of the latest 3D drainage design technology, which includes signing and sealing the first 3D drainage model as the legal document on our Polk Parkway AMG/3D pilot project for Florida’s Turnpike Enterprise.

Separately, our stormwater analysis experience goes beyond the traditional approaches. We understand the need to provide alternative solutions and continually train our drainage staff in Low Impact Design such as BAM, planter box biofiltration systems, CDS units, and regional stormwater approaches. We regularly coordinate with Florida’s water management districts and environmental regulatory agencies.
