Ordinance Approach (Utility Service Rules)
17
Local ordinances can take numerous forms to assist in improving landscape
planning and
design for water conservation. Ordinance provisions include local compliance
plus
enforcement of state requirements for irrigation licenses; tree ordinances;
landscape
ordinances; stormwater permits and building permits including plat or site
plan approvals.
Each of these approaches provide unique opportunities to save water by
ensuring that
new landscape installations are planned and designed with water conservation
in mind.
Landscape guidelines in municipal ordinances in Texas are often found
in the zoning
code. Understanding all of the potential measures which could be passed
by ordinance
requires a review of zoning codes for numerous types of land uses, and
potentially of
specially designated zones within a community. To pass the water conserving
features of
an ordinance, the utility water conservation staff must work with city
planners, and be
prepared to go to Planning and Zoning Commissions for adoption of proposals
prior to
presenting to a city council for approval. Each Home Rule City has the
potential of
approaching this problem uniquely, and the conservation staff should
work closely with
utility legal staff and city attorney(s) to ensure that ordinance provisions
fit with local
ordinance structures.
Local ordinances which focus on compliance with state irrigation licenses
need to
provide a point in the planning process and plan or permit review where
the licensed
irrigator can submit proof of license and penalty for non-compliance.
An advantage of
this approach is that the state license procedures and requirements are
in existence, and
require certain standards of training. The training ensures that irrigators
have the
knowledge to produce plans with appropriate irrigation uniformity, pressure
management, and zoning principle in mind. However, without compliance
activities to
ensure that plans are followed the water savings are not likely to be
realized.
Tree ordinances can assist in limiting the area of existing or native
landscape which is
disturbed or destroyed, thus reducing the amount of water needed for
an entirely new
landscape.
Ordinance Elements
Landscape ordinances can be included as elements in a city’s zoning
ordinance, water
conservation code, or as a separate stand alone set of guidelines. This
manual will offer an approach to designing a landscape water conserving
ordinance, or service rules for
those utilities which do not have ordinance-making powers. It is not
a comprehensive list
of all possible ordinance language – many time cities have distinct
ordinance structures
or landscape rules related to the history of ordinance passage, and these
distinctions will
need to be addressed as new and improved ordinances are passed by a city
council. Some
of the distinctions necessary for utilities which are privately held
or otherwise do not
have ordinance powers are dealt with at the end of this section. Such
utilities may use
service rules as a method for addressing required or recommended elements
in landscape
design and implementation.
There is not one comprehensive model ordinance in Texas, although there
are numerous
water conservation provisions in various ordinances throughout the state.
California has
produced a model ordinance [http://www.owue.water.ca.gov/docs/WaterOrdIndex.cfm],
and Cities of San Antonio [http://www.saws.org/conservation/ordinance/],
El Paso
[http://www.epwu.org/conservation/ordinance.html], and Austin all have
ordinance
provisions impacting water conservation year-round. Many more cities
in Texas have
year-round or summer restrictions on time of day watering, and water
waste. Examining
the wide variety of approaches which are possible, ordinances and/or
service rules can
include provisions which restrict, permit, encourage, or provide incentives
for:
- Plant Selection
- Soil depth
- Determination of soil texture, indicating the percentage of
organic matter.
- Hydrozone grouping of plants
- Regionally adapted plant lists (use the U.L.G. Database!)
- Preferences for native species
- Landscape design plan specifications
- Requirements for properly prepared landscape plans following
landscape design
practices recommended by the American Landscape Association for Xeriscape
landscapes.
- Grading Design Plans with limits on slopes or requirements
for specific groundcovers on slopes.
- Minimum depth of mulch application (2” to 3”)
in beds
- Listing of turfgrass approved species
- Excluding species such as invasive plant species, or species
not adapted to
bioregional climate conditions.
- Water Budget
- Limits on turf/landscaped area
Medians, Buffers, Basins and Entrances
Size of medians is an essential concern when determining whether a landscape
can thrive,
and whether it can be irrigated efficiently. Plant health is affected
by the heat island effect
of small landscape areas surrounded by pavement, as well as the room
available for roots
to grow. Approaches focused on irrigation system choices are dealt with
in Chapter 4.
Landscape ordinances can limit the types of plants based upon the size
of these small
landscaped areas and the specific environmental stresses that plant materials
encounter in
them.
Ensuring Success
In pursuing landscape ordinances or services rules, it is important that
a utility evaluate
its ability to ensure or enforce compliance. Compliance activities by
a municipal
government may require code enforcement personnel such building inspectors,
plumbing
inspectors or as 3rd party certifiers to certify that an ordinance has
been properly
followed. Conservation staff should communicate with all personnel involved
in
compliance and enforcement prior to finalizing ordinances or service
rules. Some
activities which should be anticipated, depending upon the approach taken
include:
- Landscape design approval
- Backflow prevention review and approval
- Meter installation/permit
- Ability to identify recommend plant species, and excluded
invasive species
- Measuring soil depth.
- Education about the ULG plant database.
Education
Like the programmatic approaches dealt with in Section 3.8, successful
ordinances and
rules require education. Without an understanding of the ordinances,
local builders,
developers, irrigation, and landscape professional and homeowners are
unlikely to
comply. During the passage of an ordinance, public meetings and hearings
can help
introduce the concept to the most affected parties. But this will not
be sufficient. Some
annual reminders of the rules in the form of bill stuffers, Public Service
Announcements
on radio, TV and in newspaper, and flyers or brochures will all assist
the utility in
informing the public and explaining its program.
Workshops for landscape professional can also provide an opportunity
to inform the
professional and development community about the ordinance provisions
as well as
voluntary or incentive programs the utility may sponsor. The need for
continuing
education by many of these professional can be met by utility cooperation
with certifying
agencies, like the TCEQ or the Texas Nursery & Landscape Association.

can be consulted to find a trainer near your utility who may be willing
to work with
your workshop efforts. |
