AGENDA ITEM SUMMARY
Meeting Date: May 20, 2015
Bulk Item: Yes X No
Division: Engineering & Public Works
Department: Wastewater
Staff Contact Person/Phone #:Wilson (453-8797)_
AGENDA ITEM WORDING: Approval for expansion of the Cudjoe Regional Wastewater system to
include 42 properties on No Name Key and 57 properties on Middle and Big Torch Keys.
ITEM BACKGROUND: FKAA recommends inclusion of an additional 99 properties located on No
Name Key, Middle Torch Key and Big Torch Key. They have developed a plan that brings the
average cost per connection for these properties to under $30,000 on No Name Key and under $25,000
for Big & Middle Torch. In the past, the cost breakpoint used for central service vs. on -site systems
has been $22,500. Inclusion of additional properties reduces the number of on -site systems to less than
100. Design and construction of on -site systems has proven more challenging than anticipated and
cost of inclusion in the central system has proven less expensive than anticipated. Centralized
treatment also offers better treatment than can be achieved in on -site systems.

From: Tom Walker, FKAA
Subject: Extension of Cudjoe Wastewater Service Area No Name, Middle Torch and Big Torch Keys
The original consideration for providing service to outlying areas required an estimated construction
>>»�
cost of less than or equal to $22,500 per connection. This cost thr rd was based solely on cost
»N
considerations which assumed an on -site treatment system cod b built for approximately $22,500
and that central sewers were less than this cost per conned$
Since these initial rules of engagement with handlingng areas wdf"t in place, many properties
have been brought into the regional service area, ��� on competitive [: ' and locations of these
properties which led to a reduction of more than to -site systems to be b�nd maintained. Also,
during this time, FKAA:
• Evaluated remaining propertid )� j ode the central ��}r° area to determine potential

f
FKAA recommendJfipt Monroety add these three islands (42 EDUs on NNK & 57 EDUs on Big &
Middle Torch) into th j /S Ou r =ommendation is based on several considerations:
1. CRWS provier level of wastewater treatment and system reliability than any on -
site system.
2. The DOH -approved on -site systems take a considerably large space (on the order of 400-600
square feet) considering installation on many small, existing properties.
3. With the conversion of many LPS areas to gravity areas, the price point for central sewers has
increased well above the $22,500 per connection in the conversion areas.
4. Property owners would much rather have central sewer services than an on -site system.
Given the approval to proceed, FKAA can have these properties available for central service by October,
2016.
