This document summarizes the low impact development design approach used for improvements at Siesta Beach Park in Sarasota, Florida. The goals were to improve aesthetics, environmental quality, and stormwater management. Features included new restrooms, landscaping, permeable parking areas with underground storage and infiltration, bioswales, and water quality treatment with an ultraviolet disinfection system. The $21.5 million project met its goals of enhancing the park while protecting water quality with sustainable stormwater infrastructure.

Permeable Pavers for Cross Walks

38. Overview – Pervious Concrete
• Pervious or no-fines Concrete –
mixture of Coarse
Aggregate, Portland
Cement, Admixtures and Water
• Increased/Enhanced Porosity due
to limited fines
• Can be placed directly on parent
soils with no aggregate sub-base
(rigid pavement type)

39. I-4 TRUCK STOP (Shoulder application)

40. FCPA – Florida Concrete Products
Association BUILDING (Orlando)

41. Overview – Permeable Pavers
• Expanded openings at the
sides/edges encouraging water to
infiltrate
• Openings are filled with small
size stone
• Many different styles/patterns

42. Permeable Pavers studied at UCF

43. ERIK TESTING
E.R.I.K. Embedded Ring Infiltrometer Kit
-In-situ, nondestructive, replicable
- Constant head test @ 1” above surface
- Measures rate of water “upstream” of sample
- Infiltrometers can be embedded from surface of
pavement down into parent soil, in order to monitor
where clogging is taking place
(ie. near the surface or deeper in the pore structure)
