AGENDA TITLE: Introduce Ordinance Amending Lodi Municipal Code Title 17 "Development Code," by
Repealing and Re-enacting Section 17.30.070 "Water Efficient Landscape
Requirements" in its Entirety
MEETING DATE: September 21, 2016
PREPARED BY: Public Works Director
RECOMMENDED ACTION: Introduce ordinance amending Lodi Municipal Code Title 17
"Development Code, "by repealing and re-enacting Section 17.30.070
"Water Efficient Landscape Requirements" in its entirety.
BACKGROUND INFORMATION: Lodi Municipal Code (LMC) Section 17.30.070 "Water Efficient
Landscape Requirements" was first introduced during the City Council
meeting on February 6, 2013 and adopted on February 20, 2013. On
July 15, 2015, the California Water Commission approved the revised Model Water Efficient Landscape
Ordinance (MWELO). The State estimates that under the revised MWELO, a typical California landscape
will use approximately 20 percent less water than landscape installed per the requirements of the previous
ordinance.
Staff has reviewed the City's existing LMC and revised Section 17.30.070 to comply with the requirements
of the State's MWELO. The changes to be incorporated are briefly described below:
• Reduces project size subject to the ordinance from 2,500 square feet to 500 square feet and now
includes a "prescriptive compliance option" for those projects between 500 and 2,500 square feet.
The prescriptive compliance option is intended to provide a more simple approach that includes
basic landscape design standards to reduce water usage.
• Updates and expand definitions.
• Revises the maximum applied water allowance. This water allowance reduces the landscape area
that can be planted with high water use plants.
• Revises soil management report requirements for multi -lot projects. Clarifies soil testing frequency
for multi -lot projects.
• Revises the landscape design plan section to address soil preparation, clarify plant selection, and to
prohibit high water use plants in street medians.
■ Revises irrigation design plan section to require high-flow sensors and dedicated landscape meters
on residential landscapes over 5,000 square feet and on commercial projects of certain size, and
clarifies the standards in which irrigation sprinklers must comply.
• Revises graywater systems section.
• Adds a storm water and rainwater retention section to encourage additional pervious surfaces such
as porous concrete and rainwater retention elements in the landscape design.
• Adds a reporting section to require local agencies to report on the implementation and enforcement
of the ordinance.

Staff has been working to establish a plan to implement the additional requirements of the MWELO. The
plan will involve a combination of in-house resources and/or outside consulting services depending on the
size and complexity of each project.
Staff recommends City Council introduce the ordinance amending Lodi Municipal Code Title 17
"Development Code, "by repealing and re-enacting Section 17.30.070 "Water Efficient Landscape
Requirements" in its entirety.
FISCAL IMPACT: Staff anticipates the revised MWELO compliance oversight will be performed
by a combination of in-house and outside resources. The cost to review,
approve, and inspect the projects subject to the MWELO is currently unknown.
Plan check and inspection costs will be evaluated as staff gains more
experience with the compliance efforts and, if needed, additional plan review
fees to recover these costs will be recommended.
FUNDING AVAILABLE: Not applicable.

heads installed in the landscape must document a distribution
uniformity low quarter of 0.65 or higher using the protocol defined
in ASABE/ICC 802-2014.
xiv. It is highly recommended that the project applicant or city inquire
with the local water purveyor about peak water operating
demands (on the water supply system) or water restrictions that
may impact the effectiveness of the irrigation system.
xv. In mulched planting areas, the use of low volume irrigation is
required to maximize water infiltration into the root zone.
xvi. Sprinkler heads and other emission devices shall have matched
precipitation rates, unless otherwise directed by the

use to a level that does not exceed the maximum applied water allowance
for existing landscapes. The maximum applied water allowance for
existing landscapes shall be calculated as: MAWA = (0.8)
(ETo)(LA)(0.62).
b. For all landscapes that do not have a meter, the city shall administer
programs that may include, but not be limited to, irrigation surveys and
irrigation audits to evaluate water use and provide recommendations as
necessary in order to prevent water waste.
2. All landscape irrigation audits shall be conducted by a certified landscape
irrigation auditor.
W. Water Waste Prevention.
1. The city shall prevent water waste resulting from inefficient landscape irrigation
by prohibiting runoff from leaving the target landscape due to low head drainage, overspray, or
other similar conditions where water flows onto adjacent property, non -irrigated areas, walks,
roadways, parking lots, or structures. Penalties for violation of these prohibitions shall be
established locally.
2. Restrictions regarding overspray and runoff may be modified if:
a. The landscape area is adjacent to permeable surfacing and no runoff
occurs; or
b. The adjacent non -permeable surfaces are designed and constructed to
drain entirely to landscaping.
X. Effective Precipitation. The city considers effective precipitation (twenty-five percent of
annual precipitation) in tracking water use and uses the following equation to calculate
maximum applied water allowance:
MAWA= (ETo - Eppt) (0.62) [(0.7 x LA) + (0.3 x SLA)] for residential areas.
MAWA= (ETo - Eppt) (0.62) [(0.45 x LA) + (0.55 x SLA)] for non-residential areas.
