3. HEEL RINGS
A. Chairman Klinkiewicz introduced the hearing item as a proposed amend-
ment to Municipal Land Use ordinance No. 348, amending Sections 18.5
and 18.11 regarding minimum size of dwellings in Planned Residential
Developments. He noted that this is a City initiated proposal. This
hearing was continued from the July 12, 1983 meeting. He then called
for staff's report.
1. Principal Planner Sandra Bonner stated there were two points she
wished to bring up in addition to the staff reports of last meeting
and this meeting. The first point is that approval of this amend-
ment to the ordinance will not affect the density of a project. It
only affects the size of the units. The second point is that the
proposed amendment to the ordinance is not a lowering of the
standards.
Based on findings in staff's reports, staff recommends that the
Planning Commission reccmmend to the City Council the adoption of
the proposed amendment to Sections 18.5(5) and 18.11 of the
Municipal Land Use Ordinance No. 348, and the adoption of the
negative declaration prepared for the environmental assessment.

mittal of that to the Redevelopment Agency and City Council (under
state law) is the responsibility of the local Planning Commission. He
I' r

explained that what was being intended for redevelopment is to provide
flood control protection for the entire cove from Tampico southward on
both east and west sides. By providing that type of flood control pro-
tection, other parts of la Quinta and areas to the east will also be
protected. Mr. Usher provided photos of areas that had been eroded by
flooding in the past explaining that after the flood control improvements
have been completed, this would not reoccur.
The Citv Manager went on to report that through Coachella Valley Water
District, the channels would be improved - probably with concrete lining -
to carry flood waters, particularly on the west side, from Bear Creek
directly down the west side of the cove to the Oleander Reservoir, which
is now the La Quinta Golf Course, which has been designed to hold flood
waters and then slowly release the water to the La Quinta Storm Evacuation
Channel to the Whitewater Channel. He stated the project will cost be-
tween $12 - $15 million dollars according to current estimates. This
cost will be handled through the issuance of bonds which will be supported
by tax increment financing through establishment of the redevelopment
project. The tax increment method of financing is one in which funds are
derived from the crrowth of taxes as new development occurs. The project
will not involve any type of assessment to property owners currently in
the Citv. It will not involve any special assessment which would other-
wise occur without redevelopment. This growth of tax increment would
develop as properties are reassessed through new development in any case,
but in this case, a portion of the tax increment would be channelled to
the Redevelopment Agency to pay for the bonds. other portions would be
passed through to other taxing agencies to recognize their needs for
continued additional growth in revenue.
Mr. Usher stated that the power of inrrinent domain will not be used to
assemble residential property for sale or disposition to private developers.
In conclusion, City Manager Usher stated that any questions the Commission
may have will be answered and informed them of the proposed Resolution
included with their packets selecting the La Quinta Redevelopment Project
Area and approving the Preliminary Plan formulated for the redevelopment
of the project area. The project area is basically the entire City south
of Avenue 50 to a northwest corner of the cove from the westerly mountains
in which Coachella Valley Water District plans to do additional flood
control work, and the entire Kennedy Ranch which is owned by LML Development
Corporation of California.
Commissioner Juan Salas reauested to know what would happen to surface
water which starts at Calle Tampico.
Mr. Usher replied that this plan is designed to handle flood waters coming
out of the mountain canyons and mountain watershed. It is not designed
to handle surface water which falls on the streets of the cove itself
from Tecate northward. That would require a system of street storm drains
and orobably curbs and qutters cdnich will be addressed separately_ most
likely. several years ,.r

Commissioner Salas explained that he wished to make everyone aware
that this plan would alleviate any catastrophic flooding, but that
there would still be flooding from surface waters.
All discussion having been caTpleted, Chairman Klimkiewicz called
for a motion.

set a special study session for August 29, 1983 at 3:00 p.m. to discuss the

To: The Honorable Chairman and Members of the Planning Commission
From: Sandra L. Bonner, Principal Planner
Date: September 13, 1983
Subject: PU7P PLAN NO. 83-031, A Request to Construct a Single -Family House or.
a Trot Located Along Calle Paloma, North of Calle Tampico; Donel Korte,
Applicant
BACKGROUND AND ANALYSIS
The Applicant is requesting approval to construct a single-family house on a .29-acre
lot located along the east side of Calle Paloma approximately 80 feet north of Calle
Tampico (see attached map). This house will be the Applicant's home.
Sitin4
The siting of the house is consistent with the zoning requirements and compatible
with the surrounding development. The house will have a 23-foot front setback,
10-foot sideyard setbacks and a 60-foot rear yard setback.
Floor Plan
The floor plan is substantially consistent with the City's adopted standards for
single-family houses. The hone will have approximately 1,545 square feet of gross
livable area (including the pool area). The plan of the house features one bedroom
with width and depth dimensions exceeding 10 feet, two bathrooms which share
a
sunken tub/shower (for a total of 1, bathrooms), an indoor swimming pop a
an
attached double -car garage with no connecting door into the house. Concerning the
connecting pedestrian door from the garage into the house, staff recommends that the
Commission make the finding that the attached garage conforms substantially with the
City's adopted standards.
Exterior Design
The overall height of the building is 14 feet, which is below the maximum 35-foot
height limit required by the R-1 zoning on this property. The house will have
stucco -coated exterior walls, a peaked roof which will be entirely screened by
parapet walls and a misiimu m 18-inch overhang located approximately 4 feet below the
top of the wall. Incorporated into the design of the overhang are 6-foot wide patio
covers over all doorways entering the house. Additional light will be provided to
the pool area by two large skylights.
Although the existing houses in this area are the traditional California ranch style
with peaked roofs, it is staffs opinion that the appearance of this,house will be
Compatible. BV the design incorporating the large patio covers :;ith ne overhang,
esoecially over the front entryway, the straight lines of the walls are effectively
broken up.

From Sandra L. Bonner, Principal Planner
Date: September 13, 1983
Subject: REVIEW OF CITY COUNCIL AMENDMENT TO SECTION 5 (d) OF A PROPOSED AMENDr=\';
TO MUNICIPAL LAND USE ORDINANCE NO. 348, AMENDING SECTIONS 18.5 AND 18.11
RD,,ARDING MINIMUM SIZE OF DWELLINGS IN PLANNED RESIDENTIAL DEVELOPMENTS;
CITY INITIATED.
C • M • • IUD,
At its August 16, 1983 hearing, the Citv Council approved the above mentioned
amendment to Municipal Land Use Ordinance No. 348 with an amendment to Section 5(d)
as recommended by staff. The City Council has referred this item back to the
Planning Commission for its consideration.
Section 5(d) reaarding when exceptions to the standards may be granted by the City
Council was approved by the Planning Commission as follows:
5. (d) The standards may be decreased or increased by the City
Council for a specific project based upon:
1. Efficiency of unit design;
2. Usability of the dwelling by the ultimate occupants;
3. Compatibility of the dwelling to the area.
As amended by the City Council, this section now reads:
:5. (d) The number of units having living area less than 1,000
square feet may be increased for a specific project if
the City Council makes the findings, including but not
limited to:
1. The location and appearance of the units are
compatible with the area in which the develop-
ment is located.
2. The amount of usable open area substantially
exceeds the 40 percent of net area as reo-uirec
by Section 18.5(2).
3. The dwellings having less than 1,000 square feet
of livable area are evenly distributed throughout
the entire project.

ANALYSIS
Staff recamended a change to Section 5(d) in response to a concern raised by
Chairman Klimkiewicz that while this section provided needed flexibility to the
ordinance, the section as originally proposed did not establish definable standards
for when exceptions could be granted by the City Council for specific projects.
The proposed amendment requires that the City Council make all three findings prior
to granting an exception to the standards limiting the number o` units which have
less than 1,000 square feet of livable area. Subsections (2) and (3) impose
standards which exceed those required for a planned residential development which
is constructed in accordance with the standards. For instance, as a trade-off for
constructing more smaller units, the developer would be required to provide addi-
tional usable open space for the residents (usable open space is that area not
covered by buildings, streets, drives or autombile storage). The requirement for
the units being evenly distributed throughout the entire project area prohibits
the clustering of all the smaller units at one location within the project.
Reconrendation
That the Planning Commission report to the City Council its support of the change
in Section 5(d) regarding when exceptions may be granted for specific projects.

From: Sandra L. Bonner, Principal Planner
Date: September 13, 1983
Subject: SUMMARY OF PLANNING COMMISSION STUDY SESSION REGARDING DESIGN TREATMENT
ALONG WASHINGTON STREET
Discussion of the Specific Plan for Washington Street was limited to design standards
for the parkway and median areas. Consideration of the design of the roadway was
deferred until such time that a Citv Engineer has been hired in September.
The following are the major items which were discussed by the Planning Commission.
Parkway Width. The Commission favored supplementing the current 12-foot-wide parkway
by requiring an additional 20-foot-wide setback for all structures and fences along
Washington Street. Thus, there would be a total 32-foot-wide strip along Washington
Street for landscaping and walkways. The C_oTinission directed staff to obtain measure-
ments on the widths of parkways for existing projects in other cities to determine if
the 20-foot setback is adequate.
Exceptions to Setback Requirement. After reviewing the plans for Laguna de Is Paz
and the proposed Isla Medtterranea, both of which are M. B. Johnson projects, the
Commission discussed the need for flexible standards to encourage the creation of
design treatments which comply with the intent of the Specific Plan.
Center Median. The majority of the Commissioners favored the installation of a center
planting strip on Washington Street on the basis that this roadway is the main entrance
to the City and that the median would significantly improve the roadways appearance.
City Manager Frank Usher discussed the possibility of having a planted center median
for that portion of Eisenhower Drive north of Avenue 50. Chairman Klimkiewicz
suggested that a center median be installed along Avenue 52 at such time that new
development occurs and this street becomes the second major entryway into the City.
Street Trees. The Commission discussed continuing the use of palm trees along
Washington Street as has been done along Highway 111 in the cities to the west.
The Commission agreed that this theme should be continued along Highway ill within
the City. There was discussion as to whether Mims should be planted along Washington
Street using robusta palms rather than date palms. The Commission agreed that street
trees are needed and that one type of tree should be predominant along the length of
Washington Street.

Landscaping of Parkways. The Commission agreed that a unifying design theme is
needed along Washington Street. The Commission discussed a desert landscaping theme
versus a theme using turf. The commission favored the use of undulating terrain or
nm:)unds to provide visual relief. The Commission directed staff to consult a landscape
architect and other desert cities regarding possible landscaping plans.
Walkways. The Commission favored the use of a meandering sidewalk and requested that
additional information be obtained by staff regarding different designs. The
Cacmi.ssion favored weaving the walkway over and through the mounds to create a more
interesting appearance.
Bike Path/Bike Lane. The Commission discussed designating a bike lane within the
roadway rather than constructing a bicycle path in the parkway. The Commission dis-
cussed the possibility of combining the pedestrian and bicycle paths to minimize the
amount of paving within the parkway. Staff reco vended against a bike lane on the
street due to safety concerns.
Iandscaoina of Center Median. After discussion, the Commission favored the use of
desert landscaping for the median as a means for reducing maintenance and watering
costs. The desert landscaping would also provide a contrast to the landscaping along
the sides of the street in the parkways which may include turf.
Maintenance of Landscaping. The Commission agreed that the homeowners of developments
should maintain all the landscaping within the parkway, but that the City would irLain-
tain the landscaping along the length of the center median. The Commission supported
the formation of a landscape maintenance district whereby homeowners along Washington
Street would be assessed for the maintenance of the median.
Undergrounding of Utilities. Commissioner Salas provided information on the require-
ments and general costs for undergrounding the existing electric distribution lines
along Washington Street. The Commission supported the undergrounding of these
facilities. A suggestion of Commissioner Salas was that the developer install the
conduit and boxes for the underground lines at the time of construction with the
wiring or actual undergrounding of the facilities to occur at a later date when the
conduit extends down the length of Washington Street. The Commission discussed the
costs of undergrounding and the possibility of speeding up the timetable for under -
grounding.

Introduction .. .
All factors point to a continually increasing popula-
tion in the Coachella Valley with no end in sight. This
increasing population will continue to strain the very
natural resources our lives depend on.
Why should anyone be interested in conserving
water? After all, there is no "water crisis" in the
Coachella Valley. However, there Is a ''water pro-
blem"! Presently, the underground water table is
recharged by imported water. Even with recharging,
the water table in the Upper Coachella Valley is
receding about three feet per year. As the water table
drops, more energy is required to pump the water the
increased distance. The additional amount of energy
required to obtain water, combined with increasing
electricity rates, could result in consumers paying
higher water rates.
Why are we urging you to use drought tolerant (low
water use) plants when you landscape? Simply
because studies show that up to seventy-five percent
of all residential water use in the Upper Coachella
Valley goes towards landscape irrigation. Therefore, a
great deal of water can be saved by planting drought
tolerant plants.
Conserving water in the landscape can be done
basically in two ways: (1) increase the efficiency of
your irrigation system, e.g. improve the design, use
low -flow sprinkler heads, reduce run-off, etc. and (2)
plant drought tolerant plants.
This book contains a list of drought tolerant plants
designed to fit most of the landscaping needs of the
Coachella Valley, offering a variety of form, size and
color. The plants were selected using information ob-
tained from a plant test project being conducted at
the Desert Water Agency Operations Center, Palm
Springs, California. The test project, which began
April 1981, is being conducted by the Soil Conserva-
tion Service, in cooperation with the Desert Water
Agency.
Drought tolerant plants can be used for: landscap-
ing and beautification, screening purposes, wildlife
food and cover, as well as windbreaks. Many also of-
fer shade during the summer months and let the sun's
warming rays in during the winter months (deciduous
trees) or, if desired, year round shade (non -deciduous
trees).
Studies have shown that air-contitioning and
heating costs may be reduced by shading the
southern and western exposures of your home. If one
uses deciduous trees to accomplish this, it will result
in reduced cooling costs during the summer months
and reduced heating costs during the winter months.
This is just one example of how, through the wise use
of drought tolerant plants, you can not only save
water, but energy too.
In addition, drought tolerant plants can be used to
serve other needs, such as erosion control, and fire
retardance. Drought tolerant plants, once establish-
ed, have the added virtue of requiring relatively little
care — a useful attribute for people with second
homes or little time for gardening.
The goal of this booklet is not to provide you with a
complete list of all drought tolerant plants, nor is it
designed to make you an expert on all facets of land-
scaping with drought tolerant plants. It is designed to
make you aware of the problems occuring in the
Coachella Valley and to provide you with enough infor-
mation so that you may better evaluate your landscap-
ing needs.

Climate And Physical Characteristics
Of The Coachella Valley .. .
The Coachella Valley, an area which extends from
Palm Springs to the Salton Sea, receives a very
limited amount of rainfall. The average annual
precipitation is two to four inches, with most occur-
ring in the form of gentle rains during the winter -
months. However, very high intensity rains can occur
during the mid -summer months, producing flash
floods
The temperatures in the Coachella Valley vary
widely. During the winter months temperatures can
reach as low as 201 to 300, with light frosts occurring
in January and early February. Summer tempera-
tures, on the other hand, are quite hot, reaching 1200
or more.
The growing season, which occurs from January to
December, is about 300 days, with some plants con-
tinuing to grow throughout the entire year.
The Coachella Vallev is surrounded by mountain
ranges, the highest being Mount San Gorgonio
(11,485 feet), with the majority of the valley floor lying
below sea level. Elevations range from a high of about
1600 feet to a low of about 250 feet below sea level.
As a result of these differences In elevations, con-
siderable variations in minimum temperature can oc-
cur within short distances. These temperature varia-
tions must be taken into account when selecting your
landscape material.
Both windstorms and sandstorms are common oc-
currences, particularly during the late spring months.
These can cause considerable damage to un-
protected soil and plants, as well as automobiles,
houses, etc. The use of windbreaks can greatly
reduce the effects of sand and wind damage and
hence, increase the amount of plants suited to your
particular area.
Soils ...
The nature of the soil at any given location depends
on the composition of the parent material. Parent
material is the weathered rock or unconsolidated
mass of material from which soils form. It largely
determines the chemical and mineralogical composi-
tion of soils.
In the Coachella Valley there are three major
sources of parent material: recent outwash, which is
mainly granitic material from the mountains surround-
ing the Coachella Valley, lacustrine deposits of Lake
Cahuita. and the weathered rock in the San Jacinto
Mountains
In general, the valley floor is made up of lacustrine
deposited soils consisting of fine textured sediments.
The alluvium and weathered rock from the surround-
ing mountains is -coarse textured near the mountains.
The soils in the Coachella Valley contain a
measurable amount of calcium carbonate and hence,
are referred to as ''calcareous'' soils. Almost all the
soils tend to be moderately alkaline (pH of 7.0 or
higher). When a soil is alkaline many cations are
precipitated (removed from solution), and such
elements as iron, manganese and phosphorus may
become unavailable to plants. (See the fertilization
section for a discussion of these deficiencies).
Irrigation And Salinity ...
"How much water should I apply to my newly
planted ornamentals?'' This is probably the most fre-
quently asked question by the novice gardener, and
one that cannot be answered by a simple statement.
There are many factors that must be considered when
trying to determine how much and how often your
plants should be watered. The needs of the particular
plant, its age, the nature of the soil (and the water), the
weather (temperature, humidity, and amount of wind),
the season, and the method of water application all
must be taken into account.
One important thing to remember is even if your
plants are drought tolerant, they still must be ade-
quately watered until they become established.
Once your plants are established. watering every
three or four days will suffice. However, if newly
established plants are over -watered, stunting of
growth and eventual death may result.
One way to avoid over or under watering your
plants is to learn how to read the soil. The easiest way
of doing this is to take a shovel into the garden and
turn one blade of soil. If the soil is dry, water it.
There are, however, some general guidelines that
may be applied to most drought tolerant ornamentals.
(1) Plants one to four feet in height provide one
gallon of water per day during summer months
(2) Plants four to ten feet in height — provide three
gallons of water per day during summer months.
(3) Plants greater than ten feet in height — may re-
quire as much as ten to twenty gallons of water per
day during the summer months.
NOTE: Reduce water application in half during
winter months
6
u J .,
-; d
Regardless of the time of year (a) Plants piantee on
coarse sandy soils may require water caily. (b) Plams
planted on fine soils may be watered every other day.
I1 you choose to water every other day, double your
application of water.
Remember, shallow watering equals shallow roots.
Plants must be deep watered in order to grow and
develop properly. Their roots develop and grow in the
presence of air, water and nutrients. Plants will root
only In the area that these are available. For example,
if only the upper one foot of soil is kept watered. roots
will develop only in the upper one foot. If roots develop
only near the surface, plants will become less drought
tolerant and more susceptible to wind damage.
Irrigation water may be applied by:
(1) Furrows or basins around the plants, in which
the water is contained while it soaks into the ground.
(2) Subsurface irrigation, in which water is put
directly into the root zone.
(3) Sprinkling, and thus providing a means of arti-
ficial rainfall.
(4) Drip irrigation and soaker hoses, in which water
is delivered slowly and for a longer period of time.
No one method of irrigation can be considered the
best type. One must take into account the type of
plant, topography, soils, climate and water supply
when designing an irrigation system.
Mulches can be used to help conserve water. By
placing a mulch on the surface of the soil, your soil
will be kept cool and moist for a longer period of time
Mulches can also be used to reduce the amount of
weeds.
Many materials can be used for mulches: Compost,
animal manures, leaves, sawdust, bark chips, straw,
even shredded newspapers make very effective
mulches.
Salinity in the soil is a common problem in some
areas of the Coachella Valley. In most cases, salinity
may be reduced by providing necessary drainage and
adequate amounts of water.
Plants vary in their tolerants to salts. If the soils in
your area have an unusually high concentration of
salts, it may be a good idea to select plants that are
more salt tolerant.
It Is also a good practice to soak the area to be
planted with water four or five days prior to planting.
This will assure deep washing of toxic salts away from
the root zone, thus reducing the chances of salt
damage to your plants.
11
Fertilization .. .
From time to time, plants require the addition of
organic or inorganic fertilizers to ensure healthy
growth and development.
Physical, as well as chemical properties of soils in-
fluence the amount of nutrients held by the soil. This
in turn, can effect the availability of nutrients to plants.
The individual properties of your soil can determine
the amount and frequency of fertilization necessary.
The finer the soil, the more nutrients and water will be
held within the soil. For example, if one were applying
nitrogen fertilizer to a soil, a sandy soil (course tex-
tured soil)would require more frequent applications of
fertilizer and In smaller amounts, than a clay soil (fine
textured soil).
Sixteen elements have been found essential for
plant growth. If the availability of any one element is
limited, the plant may not grow and/or develop as
desired- (See table 1).

Of these sixteen, carbon, oxygen and hydrogen are
supplied by the air and water, while the remaining thir-
teen, with the exception of nitrogen, may be supplied
primarily by the soil. Many of these elements are
referred to as "trace elements'' and are needed only
in very small amounts. Trace elements are present in
most soils and therefore it is usually not necessary to
add them through fertilization.
The elements that may have to be supplied
through fertilization are nitrogen, phosphorus,
potassium, iron, zinc, manganese and copper. Of
these, nitrogen is usually present in the least
amount. Nitrogen is used in large quantities by
plants; it is also easily lost by the leaching action
of rainfall or irrigation, and is eagerly used up by
soil organisms. As a result, nitrogen must be add-
ed to the soil from time to time if good growth is to
be expected. Phosphorus and potassium are pre-
sent in the mineral particles of most soils, but
they become available to plants so slowly that
supplementary feedings are often advisable.
The high levels of calcium in Coachella Valley
soils can result in a condition referred to as
"calcium induced chlorosis.'' This condition
results when the high levels of calcium in the soil
restrict iron, phosphorus and manganese from be-
ing taken in by the plant. It is therefore also
necessary to apply iron occasionally.
Zinc and copper may become deficient in areas
formerly used for livestock. such as corrals. These
deficiencies are usually brought about by heavy addi-
tions of manure to the soil
An imbalance of available nutrients can also cause
nutrient deficiencies. Nutrient deficiencies and toxic

your local Soil Conservation Service or County

Soil reaction (degree of acidity or alkalinity) can ef-
fect the availability to plant roots of the essential
nutrients present in the soil, whether they occur
naturally or are added by man. In Figure 1, page 10
the width of the bar for each nutrient shows the
relative availability of each element at different soil
reactions. For example, at a pH of 8 the availability of
phosporus. iron, manganese. boron, copper and zinc
is limited.
Most nutrients, when applied in excess, may cause
toxic symptoms and ultimately result in death to the
growing plants. This potential problem may be avoid-
ed by having your fertilizer reauirements determined
by a qualified laboratory test.
In most cases nitrogen fertilizers may be applied
safely. As a general rule, when dealing with trees less
than three feet in height, one tablespoon of nitrogen
fertilizer should be evenly spread around the base of
the tree. For trees three to ten feet in height, spread
one-half cup of nitrogen fertilizer evenly around the
tree. For trees over ten feet in height, nitrogen re-
quirements can be determined by leaf analysis.
Very small amounts of other elements may be re-
quired to correct deficiencies.
Remember, these are general guidelines recarding
fertilizer application. For best results, always follow
the fertilizer manufacturer's recommendations

Seven Common Misconceptions Regarding
Drought Tolerant Plants
1. All California Native Plants Are Drought Tolerant.
Many native plants grow well along streams and require
no irrigation or rainfall. These plants draw a great deal of
water from the stream and would not tolerate a drought if
they were removed from their water source
2. All Drought Tolerant Plants Are Native -
Many imported plants come from Mediterranean
climates simular to California's and do very well here with
minimal watering. Many of these reproduce and flourish
with little or no assistance from people.
3. Drought Tolerant Plants Never Need To Be Watered.
Even drought tolerant plants must be watered until their
root system becomes established. After a drought tolerant
plant becomes established, (usually one to two years) it will
require little watering
4. Using Drought Tolerant Plants In
Landscapes Is A New Idea.
Juniper, Rosemary shrubs, Cotoneaster, Bougainvillea
and Pyracantha are just a few examples of plants that you
can commonly find in your own yard or neighborhood that
require little or no water once they are established.
5. Drought Tolerant Landscapes Consist Of
Sand, Rocks, And Desert Plants.
There are probably some lush, green, flowering drought
resistant plants in your yard already. It is not necessary to
give up a lush green yard in the interest of water conserva-
tion
6 We Will Not Have The Same Landscaping Options
As We Have Now If We Use Drought Tolerant Plants.
Water conserving ground covers, turf substitutes,
hedges, shrubs, shade trees and flowering plants are all
available in drought tolerant varieties. Some are even fire
retardent.
7. Drought Tolerant Plants Can Be Successfully Combined
With More Water Demanding Plants.
Drought tolerant plants should be grouped together in
order to conserve water. Some drought tolerant plants are
susceptible to diseases or root rot when over -watered.
