Re: Hifllsborough River Flood Profile Maps

Dear Mr. Correia:

The maps you requested on August 22, 1973 are enclosed. You will note at
various points on the map that the nean annual flood (MAF) elevation has
been marked In red. 1

A permit is required from this office for all types of work below the
ordinary high water level of a lake or stream which is a "Work of the
"District". For easy reference, we use the mean annual flood as being
equivalent to the ordinary high water level. Present policy is to pro-
hibit the placement of fill or dwelling structures within the area of
the ordinary high water.

In regards to land development, we suggest that you consider the following:

1. Building construction not to take place on land flooded by the
25-year flood.

2. Land fill not be placed below an elevation flooded by the 10-year

3. Land lying between the limits of the 10-year and 25-year flood
be used for building construction only if:

(a) A retention area of equal water storage to that filled is
created on the property.

(b). No especially unique hydrologic or ecologic areas are filled.
(c) The property is filled to at least the elevation of the 25-
year flood. (Hlllsborough County may require fill elevations
for greater flood frequency.)
4. Drainage considerations:

(a) Water level in the shallow, water-table aquifer should not

be lowered below an average level.

(b) Amount or rate of runoff that existed on the property prior
to development should not be changed.

(w Depth of drainage ch nels should controlled b the depth J Q
the clay confining layr of the Fl1 idan Aquifer -this co rol
tbe dete ined by teC boring aloryfthe proposed inage rltes.

(d) Drainage plan should include utilization of cypress heads as
green areas and as natural water retention basins. In addition
to these natural retention basins, other water retention basins
should be considered within the property.

(e) Drainage into tidal waters should have adequate control
structures to prevent salt water intrusion.

Enclosed are copies of Chapter 16CB-l and 16CC of the Florida Administrative
Code. Chapter 16CB-1 explains the permit system and defines and designates
many of the water areas presently classified as a "Work of the District".
Chapter 16CC explains drilling regulations and water use regulations.

Very truly yours,

Engineer, Permits Department
