(Ordinance 2912 adopted 7/22/19)
Notice of the adoption of this division at a regular city council
meeting was posted and interested members of the public were given
an opportunity to express opinions and concerns regarding the plan.
(Ordinance 2912 adopted 7/22/19)
(a) The city will inform and educate the public about its drought contingency
plan by the following means:
(1) Making the plan available to the public through the city's website
at www.cityofkaty.com.
(2) Notifying local organizations, schools, and civic groups that city
staff members are available to make presentations on the drought contingency
plan.

drought stage changes, the city will notify local media of the issues,
the drought response stage, and the specific actions required of the
public. The information will also be publicized on the city's website,
www.cityofkaty.com. Billing inserts or mail-outs will also be used
as appropriate.
(Ordinance 2912 adopted 7/22/19)
(a)
Initiation.
(1)
The mayor or his/her official designee may order the implementation
of a drought response stage or water emergency when one or more of
the trigger conditions for that stage is met. The following actions
will be taken when a drought stage is initiated:
(A) The public will be notified through local media,
website postings, message boards, and other communication strategies
as they are developed.
(B) If any mandatory provisions of the drought contingency
plan are activated, the city will notify the executive director of
the TCEQ within five business days
(2)
For other trigger conditions, the mayor or his/her designee
may decide not to order the implementation of a drought response stage
or water emergency even though one or more of the trigger criteria
for the stage are met. Factors that could influence such a decision
include, but are not limited to, the time of the year, weather conditions,
the anticipation of replenished water supplies, or the anticipation
that additional facilities will become available to meet needs.
(b)
Termination.
(1)
The mayor or official designee may order the termination of
a drought response stage or water emergency when the conditions for
termination are met or at his/her discretion. The following actions
will be taken when a drought stage is terminated:
(A) The public will be notified through local media,
website postings, message boards, and other communication strategies
as they developed.
(B) When any mandatory provisions of the drought contingency
plan that have been activated are terminated, the city will notify
the executive director of the TCEQ within five business days.
(2)
The mayor or his/her designee may decide not to order the termination
of a drought response stage or water emergency even though the conditions
for termination of the stage are met. Factors that could influence
such a decision include, but are not limited to, the time of the year,
weather conditions, or the anticipation of potential changed conditions
that warrant the continuation of the drought stage.

75% of total water well pumpage for three (3) consecutive days;
(ii) Water demand for all or part of the delivery system
approaches delivery capacity because delivery capacity is inadequate;
(iii) The supply source becomes contaminated;
(iv) The water supply system is unable to deliver water
due to the failure or damage of major water system components; or

stage 1.
The goal for water use reduction under stage
1, mild, is a 5 percent of water use compared to baseline historical
monthly average water usage as calculated by the city (based on the
water usage data over the previous 12-month period). The purpose of
actions under stage 1, mild, is to raise public awareness of potential
drought problems. The mayor or his/her designee can order the implementation
of any of the actions listed below, as deemed necessary:

water use.
(iii) Review the problems that caused the initiation
of stage 1.
(iv) Notify major water users and work with them to

equals delivery capacity because delivery capacity is inadequate;
(iii) The supply source becomes contaminated;
(iv) The water supply system is unable to deliver water
due to the failure or damage of major water system components; or
(v) Water demand is approaching the limit of the permitted
supply.

caused the initiation of stage 2 no longer prevail. Stage 1 becomes
operative on termination of stage 2.
|
(B) Goal for use reduction and actions available under
stage 2.

2, moderate, is a 10 percent of water use compared to baseline historical
monthly average water usage as calculated by the city (based on the
water usage data over the previous 12-month period). The mayor or
his/her designee can order the implementation of any of the actions
listed below, as deemed necessary:
