A. The
purpose of this chapter is to establish landscaping water use standards
consistent with the development landscape design requirements established
by the Water Conservation in Landscaping Act (the "California Landscaping
Act"),
Government Code Section 65591 et seq. In that legislation,
the State Legislature determined that the state's water resources
are in limited supply and recognized that while landscaping is essential
to the quality of life in California, landscape design, installation,
maintenance and management must be water efficient. Consistent with
the legislature's findings, this chapter:
1. Promotes
the values and benefits of landscapes while recognizing the need to
utilize water and other resources as efficiently as possible;
2. Establishes
a structure for planning, designing, installing, maintaining and managing
water efficient landscapes in new construction;
3. Promotes
the use, when available, of tertiary treated recycled water to irrigate
landscaping;
4. Provides
regulations that are at least as effective in conserving water as
the state's Model Water Efficient Landscape Ordinance (MWELO);
5. Encourages
water users of existing landscapes to use water efficiently and eliminate
waste;
6. Provides
minimum planting requirements to ensure new landscape has sufficient
plant materials in order reduce gas emissions and heat island effect,
create shady and pleasant outdoor spaces, and beautify the city;
7. Encourages
edible plants and enhances community agriculture.
(Ord. 387 § 3, 2010; Ord. 436 § 1, 2016)
This chapter implements the Efficiency Regulations in Landscaping
Act. The requirements of this chapter reduce water use associated
with irrigation of outdoor landscaping by designing, installing and
maintaining water efficient landscapes consistent with the water allowance.
The provisions of this chapter are equivalent to and at least as effective
as the provisions of the state Model Landscape Ordinance because the
calculation of maximum applied water allowance.
The requirements herein are intended to reduce water usage in
Lemon Grove to the same extent as the Model Landscape Ordinance prepared
by the state of California. In implementing this law, the city shall
endeavor to apply the law in a manner, which will result in long-term
water savings to the citizens of the state as required, by law. The
water savings shall be achieved through permanent landscape rules
using irrigation management, greater use of drought-tolerant plantings
and improved design criteria.
In adopting this chapter, the city council finds and determines
that this chapter will be as effective as the state Model Landscape
Ordinance. The threshold regulations are based on those in the state
Model Landscape Ordinance.
