The owner of Lot 46, Block 1, Wynter Park Subdivision No. I has requested the septic
system serving the house on the lot be upgraded for four bedrooms. The attached site
plan shows the location of the 1,250-gallon tank and the absorption trench. Sufficient
area exists on the lot for the larger system and no conflicts are apparent. The lot is
served by a community water system and all setback requirements are met. Please
revise Permit No. SW010063 to allow a four bedroom septic system. Thank you for
your assistance with this modification.

Septic System Design and Permit Application
· , . . . Impacts to Adjacent Properties
Dear Onsite Services Engineer:.
.The existing s~ptic system on Lot 46, Block 1,.Wynter Park Subdivision No. 1 has failed
and must be replaced. We are therefore applyIng for a permit to construct a new system
on the lot to'serve the existing three-bedroom home. The attached Site' Pla~ and
backup documentation identify the location and configuration of the new se, ptic system'
and the parameters used In the design. It also shows the location of the ex~sting septic
system, absorption crib and water service line, ·Existing drainage pattems are shown
and will not be altered by the development of the lot. The existing septic tank will be
crushed, backfilled and abandoned In place. The cdb will also be abandoned after .-
crushing and backfilling. The cdb is currentfy located in the garage and the septic tank
" is under the porc~ of the house. ' · "
A test.hole was placed at the proposed location for the new absorption trench and
.. revealed gravel with varying degrees of silt.· No groundwater was noted in the test
· holes dudng excavation and none was noted dudng the monitoring period.·. The soil
' percolated at a rate faster than 1 minute per inch, but the majodty of the material in the
hole passed the. No. 4 Seive indicating a sand liner was not necessary. We are
therefore proposing to place ~, 3' w~de by. 27' !ong by 7'. effective depth absorption
trench to treat the septic effluent, :The p~pe wIll be· placed at 3' below the existing
g."ound surface and the total depth of the trench will be 10'..'. 'A minimum of 3' of cover
will be placed over the bed to prevent frost penetration and possible freezing.
· . The ground surface on the'lot slopes as shown on the attached Site Plan with'slight
~rades from s,outh to north and west to east, The area for the new absorpt on trench,
owever, is fa[rty fiat. The new trench will be constructed parallel to the contours of the
,surf'ace in conformance with Municipal requirements. Grading will be accomplished to
assure surf,a, ce drainage is away, from the new trenches. The existing drainage pattern
. on the lot w~ll not be affected dunng development,
· if the'system is cohstructed In accordance with our design 'the following st~temen'ts
