DATE: September 11, 1991
TO: Members of the City Council and Drought Committee
FROM: Don Froelich, Drought Committee Member
SUBJECT: PRACTICES VS. PERCENTAGE REDUCTION IN WATER USE
DISCUSSION
In January and February of this year, it has become very apparent that
California was going into the fifth year of a drought. Many communities,
especially in the Santa Barbara area, were reducing the deliveries of water to
their customers by upwards of 40 percent. Much of Southern California was
looking at the prospects of a 30 to 40 percent reduction in supply by summer.
Many communities started developing ordinances that contained a phased
reduction in water use to accommodate the prospects of water shortages. The
City of Santa Clarita likewise developed an Ordinance that both prohibited
wasteful uses of water and a goal to reduce water use by 254. This level of
reduction was based on a review of anticipated water supplies and water
demands. This effort was very similar to that being done in other communities.
The State of California requested that all communities develop drought
contingency plans for a possible .504 reduction in water supplies. The State
was also developing a "water bank" so that communities would obtain water
under the State program. To be eligible, a community was required to have a
program in place to reduce water use by 254. The need for the 254 reduction
was based both on available supplies and eligibility to participate in the
State program.
A 254 reduction creates a substantial hardship. It means that a typical user
would have to substantially reduce outdoor water use with a significant
portion of the landscaping not be watered. Also, a conscious reduction in
indoor water use would also have to occur. For business and industry, there
would be a reduction in the number of products that could be produced and
possible reduction in employment. Therefore, this level of reduction should
only be imposed when necessary.
In March, the State had a significant amount of rain and snow. This
dramatically increased the snow pack in Northern California and produced near
normal rainfall in Southern California. This substantially altered the water
supply conditions by reducing the possible severity of the water shortage.
Communities that were facing 30 . to 404 reduction were now looking at 10 to
204. Areas with significant groundwater supplies had essentially a full
supply.

CITY COUNCIL AND DROUGHT COMMITTEE

After the first few meetings .of -the Drought Committee, it became apparent
based on information from the water purveyors that the -Santa Clarita Valley
(SCV) had essentially a full supply. The purveyors were of the opinion that
little need existed for any reduction in use except for possible system
limitations during peak demand periods. The possibilities of shortages would
be related more to the reliability of the emergency backup in the water
delivery system than deficiencies in water supply. This raised the issue as
to whether the City should continue to advocate a 25% reduction in water use
when there was no water shortage. Continuing to advocate a large reduction
with a full water supply could create a credibility problem during future
droughts.
Based on a full supply of water, the Drought Committee considered abandoning
the 25% reduction goal, recommending a lower percentage reduction, and
eliminating any reference to a percentage reduction. The Committee looked at
a 10% reduction just to keep conservation in the minds of the users or a
program based on a continuation of the conservation practices in the
Ordinance. In other words, should the conservation effort be a "percentage or
a practice approach?" After considerable discussion, it was felt that absent
changes in water supply conditions, the SCV's conservation program should be
based on elimination of wasteful practices.
This approach is consistent with the development of "best management
practices" (BMP's) at the State level. The BMP's are water conservation
practices and programs to be implemented by all agencies. within the State.
There are no specific percentage reductions incorporated -- only practices.
The elimination of specific percentage reduction numbers in the conservation
Ordinance. is appropriate because water supplies are adequate to meet all
demands. The prohibition against wasteful practices should continue as part
of the new water ethic. If water supply conditions change for the worse, the
Drought Committee can report to the City on the need for implementing specific
reductions in water use.
In addition to the recommendation on the percentage goal, the Committee would
like the Council to consider three other recommended modifications presented
in our first .report to the Council on June 25, 1991. These modifications are
as follows:
1. The Ordinance restrict watering times to 6:00 p.m. to 8:00 a.m., and only
on every other day. This results in over -watering and excessive runoff.
Watering every other day will be too stressful for landscaping in Santa
Clarita's hot summer sun.
Recommendation: Modify.the Drought Ordinance to allow watering each day,
for no more than 10 minutes per watering station or cycle.
2. Commercial gardeners are only restricted from watering lawns between
10:00 a.m. and 3:00 p.m., even if the property under their care is
residential. This causes .some confusion in the enforcement and creates
the impression that some residents are not being subject to the Ordinance.

Recommendation: Prohibit the watering of all residential lawns between
8:00 a.m. and 6:00 p.m.
3. The recycling regulations require that glass bottles be washed out prior
to placing them in the green barrels. This seems to be a waste of
water. The .Public Works Department has indicated- that it is not
necessary to thoroughly clean all bottles, only to remove the heavier
deposits.
Recommendation: Reduce the requirement that bottles be washed prior to
placement in the City's recycling containers.
RECOMMENDATION
1. The Council eliminate the specific. reduction in water use from the
Ordinance but that prohibition against wasteful water use practices
continue and should.be monitored.
2. The Council consider the recommended modifications to. the Ordinance
relating to water every day, prohibiting watering of all residential
lawns and deleting the bottle washing requirement.
