ORDER N0.28420
CHANGE IN FLOOD DAMAGE PREVENTION ORDER # 26463
On this the 24th day of November 2003 upon motion made by Commissioner Letz,
Seconded by Commissioner Baldwin, the Court unanimously approved by a vote of 3-0-
1 to approve the changes of #1 & #2 only in the Flood Damage Prevention Order # 26463
as recommended by the Kerr County Engineer/Floodplain Administrator as follows;
1. Article 4, Section B (6): Change TNRCC to TCEQ
2. Article 4, Section B (9) currently states:
(9) When a regulatory floodway has not been designated, the Floodplain
Administrator must require that no new construction, substantial
improvements, or other development (including fill) shall be permitted
within Zones Al-3 0 and AE on the community's FIRM unless it is
demonstrated that the cumulative effect of the proposed development,
when combined with all other existing and anticipated development, will
not increase the water surface elevation of the base flood more than
one foot at any point within the community.
As development progresses in the "A" Zone, the "ultimate base flood elevation" will be
one foot higher than the current Flood Insurance Rate Map (FIRM) Base Flood
Elevation, BFE.
Therefore the base flood elevation in Article 5, Section B from "elevated to or above the
base flood elevation" will be changed to "elevated one foot above the base flood
elevation."

MEMORANDUM
TO: Commissioner's Court ,
FROM: Franklin Johnston, P.E., Kerr County Engineer/Floodplain Administrator
DATE: November 18, 2003
SUBJECT: Consider Changes in Flood Damage Prevention Order #26463
1. Article 4, Section B (6): Change TNRCC to TCEQ.
2. Article 4, Section B (9) currently states:
(9) When a regulatory floodway has not been designated, the Floodplain Administrator
must require that no new construction, substantial improvements, or other development
(including fill) shall be permitted within Zones Al -3 0 and AE on the community's FIRM
unless it is demonstrated that the cumulative effect of the proposed development, when
combined with all other existing and anticipated development, will not increase the water
surface elevation of the base flood more than one foot at any point within the
community.
As development progresses in the "A" Zone, the "ultimate base flood elevation" will be
one foot higher than the current Flood Insurance Rate Map (FIRM) Base Flood Elevation,
BFE.
I would recommend changing the base flood elevation in Article 5, Section B from "elevated
to or above the base flood elevation" to "elevated one foot above the base flood elevation."
It is my opinion that this change will help Kerr County meet its STATEMENT OF PURPOSE,
found in Article 1, Section C & D.
3. Article 5, Section C, add the following to Item 4:
"Any lot which is partially located within the flood hazard area shall have a minimum of one (1)
acre outside the flood hazard area. No lot shall be entirely within the Area of Special Flood
Hazard, as defined in Article 2".

Specie! Flood Hazard Area
Area of floodploin that could be

Flood elevation before
encroachment
The Floodway is the channel of a
river or other watercourse and
the adjacent land areas that must
be reserved i n order to pass the
base flood discharge without
increasing flood depths.
Computer models of the
floodplain are used to simulate
"encroachment'' or fill in the flood
fringe in order to predict where
and how much the base flood
elevation would increase if the
floodplain is allowed to be filled.
For any proposed Hoodway development, before a local flood~ain permit can be issued, the applicant
must provide evidence that "no rise" will occur (see page 32). You may need a qualified engineer to
make sure your proposed project won't increase flooding on other properties.
