AGENDA ITEM WORDING: Approval for use of suitable County owned parcels in the Sands
Subdivision of Big Pine Key for stormwater drainage infrastructure for the Sea Level Rise Pilot
Project.
ITEM BACKGROUND:
The engineering design for the Sea Level Rise Pilot Project for the Sands Subdivision in Big Pine
Key requires installation of drainage system pump station equipment. Due to safety and design
considerations, the above ground drainage system equipment will need to be installed partially on
the Right of Way and partially on the County owned Tier 1 ROGO lot RE number: 00306160-
000000, located on the SE corner of Father Tony Way/Avenue H. Alternate lots have been identified
for purchase by the County (RE 00302870, 00302880, 00304870) if this lot is not approved for use,
although use of another lot will require purchase by the County and some redesign by the Engineer
of Record.
The above ground equipment includes a fenced area with a concrete slab for electrical equipment, a
generator and transformer and will occupy approximately 20 feet by 85 feet of the lot running
parallel to Father Tony Way. There will be 5 underground structures to house the pump station
equipment and appurtenances (under Father Tony Way) which includes a valve box, 2 wet wells, an
inlet structure and a treatment unit. (see attached schematic).
The intent of the design is to lessen the severity of flooding and decrease predicted flood damage.
The County adopted an interim standard methodology for adapting transportation infrastructure for
sea level rise in January 2017, based on the Sea Level Rise Pilot Project Report. Based on the report,
the Sands Community specified roads should be designed to 11 inches of elevation NAVD88 and the
recommended drainage solution is a pretreated pressurized closed system.
