CASE NO.: DO WE WANT ONE?
REQUEST: APPROVE AN ELEVATED POLE MOUNTED SOLAR PANEL FOR
THE SOUTHERN CALIFORNIA GAS COMPANY AND CONSIDER
A POLICY FOR FUTURE ABOVE GROUND FACILITIES FOR THEIR
AGENCY
LOCATION: CAMINO PALMS DRIVE AND CRESTVIEW TERRACE
(ATTACHMENT #1)
APPLICANT: MR. MIKE MCGUIRE
PROPERTY
OWNER: PUBLIC PROPERTY
ENVIRONMENTAL
CONSIDERATION: SUPPLEMENTAL EQUIPMENT INSTALLED IN THE PUBLIC
RIGHTS-OF-WAY FOR PUBLIC AGENCY USAGE IS EXEMPT
FROM THE CALIFORNIA ENVIRONMENTAL QUALITY ACT BASED
ON SECTION 15301, CLASS 1(B) BECAUSE IT INVOLVES MINOR
ALTERATION OF EXISTING PUBLIC FACILITIES.
BACKGROUND:
Site Background
On November 1, 1996, Mr. Mike McGuire of the Southern California Gas Company,
submitted information to staff concerning the installation of a 20 -foot high pole with a solar
panel on top in the street rights-of-way of Camino Palms Drive and Crestview Terrace.
The purpose of the new equipment is to provide a power source for their existing
underground gas lines valves. The information is attached (Attachment #2). Besides the
pole mounted structure, the applicant also provides information on a ground -mounted
pedestal box which measures 24 -inches wide by 5 -feet high by 18 -inches long which are
also available in certain instances. The applicant states that their solar panel option is
the most cost-effective alternative for this site because they do not need to provide an
electric meter for their new equipment since the solar panel provides an adequate power
STRT111,12A
source. The applicant has stated to staff that they would like the Planning Commission to
recommend approval of the pole mounted solar panel for this site to assist their service or
maintenance needs. Additionally, they have other sites in the City which may need this
type of equipment as the need arises.
STATEMENT OF THE ISSUES:
Issue #1 - General Plan/Zoning Code Consistency
The properties surrounding this area are vacant or developed with single family houses.
The properties are zoned RL (Low Density Residential) by the Municipal Zoning
Ordinance.
The policies for this type of improvement are addressed in Chapter 7 (Infrastructure and
Public Services Element) of the General Plan. The purpose of the element is to establish
official City policy which: "Provides for a coordinated system of infrastructure and public
services to adequately serve the City at full buildout."° Policy 7-1.4.1 of Chapter 7 further -
states that the City shall coordinate with the Southern California Gas Company to ensure
the perpetual delivery and accessibility of natural gas to serve all La Quinta residents. To
implement these policies, Table IPS -3 of Chapter 7 requires new infrastructure
improvements to be sensitive to the areas where they are placed (i.e., aesthetic integrate).
The improvements whether above or below ground shall "... visually match the character
of the surrounding development." This request, as proposed, is not sensitive to the
surrounding neighborhood as proposed. Staff will address this issue in more detail in the
following sections of the report.
Issue #2 - Health and Safety Concerns
The undergrou�as lines that are in this area serve residential and commercial
properties in the City and surrounding municipalities. The applicant is proposing a solar
power source help shut off the gas line valves for servicing by their company and in case
of an emergency. The Gas Company requires these supplemental facilities to meet their
day-to-day business needs and supply natural gas to City residents. No major heath and
safety concerns were found other than possible safety risk that occurs when pole mounted
structures are knocked over accidentally by vehicles or during natural disasters.
Staff Comments
Staff supports the applicant's desire to install solar panel equipment to augment their
infrastructure facilities because this type of equipment is environmentally sensitive and
cost effective. However, pole mounted equipment in a residential district without proper
STRT111,12A
landscape screening would be offensive to this low density area. Staff would advocate
ground mounted facilities for residential areas and pole mounted equipment in commercial
areas provided landscaping or buildings screen the equipment depending on the location
being considered. Another possible solution would be to permit the installation of a solar
panel on an existing Imperial Irrigation District utility pole to eliminate the need for a new
vertical pole structure in thin residential neighborhood. All design solutions shall be
aesthetically pleasing and be approved by City staff prior to installation or placement.
Adopt Minute Motion No. 96- creating a policy for the Southern California Gas
Company to permit accessory equipment for their existing infrastructure facilities provided
low-level, pedestal mounted equipment or structures are used in residential neighborhoods
unless the solar panel(s) can be attached to an existing utility pole. Pole mounted
equipment can be used in commercial districts if screened by landscaping or buildings to
be approved by the Public Works and Community Development Departments. The
placement of any new accessory equipment or structures in the City shall adhere to the
provisions of Chapter 7 of the City's General Plan.

Cathodic Protection Systems
Galvanic Anodes
EC15--NE I
_ll
I'C)Y-1W - J_
CITY OF LAQUINTA
PLANNING DEPARTMENT
Galvanic anodes are used when no outside power source is available.The driving
potential is usually quite small (less than one volt) and, consequently, the current output
is equally small.
As a result of the small current output, multiple anode installations are required. This
presents a problem in designing a Cathodic Protection area. Smaller areas are
necessary, usually less than 10,000' and additional anodes are needed. For example, a
typical Galvanic Anode system is approximately 5000' in length and requires 5 anode
locations. Because the anode corrodes in order to produce the protective current it is
consumed over a period of time. Consumption of the anode material gives it a finite life.
When completely expended, it must be replaced if the system is to continue operation.
Installation of multiple anodes can, in some cases, be cost effective for smaller areas,
but in other cases may be uneconomic. Many Cathodic Protection systems require up
to 20 amps or more. Use of multiple anodes for such an installation could be both
physically and economically undesirable. The need for higher current led to the
development of the Impressed Current system.
Impressed Current System
As the required current for a system becomes larger, there comes a point at which the
use of a galvanic system is unacceptable. This may be because of excessive cost,
limitation of space, etc. At this point the impressed Current system comes into play. The
theory of operation of these systems are exactly the same as that of the Galvanic
Anode type. The difference between the systems is the power source.The galvanic
system derived it's power from the difference between two metals, the power for an
impressed current comes from commercial power. The impressed current must be
connected to a source of electrical energy.
While the principles of Cathodic Protection remain the same for both the galvanic and
impressed systems, there are several very different characteristics:
1. Impressed current systems require the use of an external AC power source.
They are not self generating as in the case of a galvanic system.
2. Impressed systems are not limited by a low driving voltage and consequently
have a theoretically unlimited output capacity.
3. Current output of a rectifier is normally adjustable over a wide range. This
feature makes the system highly versatile and readily adaptable to changes
within the protected area.
4. Development of low consumption anode materials has made it possible to
design impressed current systems with a very long life expectancy.

I have spoken with Christine about your request, and we both agreed that Planning Commission
approval would not be required if you install ground mounted rectifier equipment at Camino Palms
and Crestview Terrace. This type of request can be approved by the Community Development
Director. However, if you plan to install pole mounted rectifiers in the City soon, we would request
Commission review on Nov. 12th.
Please call me when you receive this transmittal. Thank you.
