PRELIMINARY STATUS REPORT -
LAKE WATER LEVEL - STREET CONDITIONS
Tuscawilla Section 4 Street Conditions
1. First off, let me say that the conditions experienced
this year are not unusual compared to similar problems occuring
in other cities and subdivisions in various sections of the
county. This is the first year, recently, that we have had a
normal or above normal rainfall and high ground water tables
for the last several years or since this section was built.
In problem soil or suspect soil areas, under drain should have
been installed at time of construction by the developers'
contractor or an alternate base material used in the suspect
soil areas. We have not been able to ascertain at this time
4It to what extent this was done.
From the field investigation to date, it appears there
may be considerable area which should have been so treated in
this section.
.
2. The lake level problem is more easily solved than
the street problem. The developer modified the structure as
originally designed and added 3.5 feet to the sides of the inlet
structure and removed the open throat feature from around the
top grate or put the top grate flush on top of the raised side
walls. This resulted in less than 1 ft. freeboard between the
top of the structure and the down hill lots.
~1e would recommend that measures be made to gradually
lower the lake level and observe its affect of the adjacent
ground water table,then after hearings or whatever are held to
establish the lake level, and its allowed range, the structure

should be remodeled to provide the safety factor originally
intended and the control and maintenan~e arrangements be drawn
up.
3. The major problem we see at this time lS the deter-
ioration of the streets in several areas of this section.
Emergency measures should be taken to reduce or all but eliminate
traffic on the problem areas until the ground water drops or
can be controlled by addition of underdrains. Once this water
table can be brought under control, tests will be needed to
actually determine the extent of past damage and recommend action.
~1e have a quotation for the soils consultant on this work for
all the areas marked in orange on our work sheet. As you can
see, all of the problem areas are not in close proximity to the
4It lake and its high water level. There are some other suspect
areas, but the pavement had not yet started to break down and
there may not require any action.
The cost of the under drain system could really be ~xpensive
as would the rework of the base in the broken up areas and
resurfacing. Some of the bad areas need to be barr~caded as
soon as possible and repair started by controlling the water
table and then start the reprocess~ng of the base and resurface
after all areas are ready.
