REPRESENTATIVE:
BOCC 1210312007 cM
Amend the text of County Zoning Resolution of
1978, as amended, to include "Solar Power
Generating Facilities" as a Special Use in the
Agricu ltu ritlResidential/Ru ral Density (AR RD)
Colorado RockY Mountain School
Balcomb & Green, P'C' (Larry Green)
I. BACKGROUND
cororado Rocky Mountain schoor (cRMs) has applied for a special Use Permit (sUP) to
construct a ground mounted Solar Power Generating System (SPGS) also known as a solar
"iir, * in"bnfr,fS."rfrt in Carbondale. Presentty, tl'ris type of system is not listed as a use
in any of the County's zoning districts; iherefore, the Applic#t has applied to amend the text of
the Zoning Resolution to inc'iude tne use as a special use in the Agricuttural/Residential/Rural
Density (ARRD). RJOitionatly, the nppft"nt is pursing a Special ose Permit for their specific
proleci concurrently with this proposed text amendment.
staff brought the proposed special Use Permit Application to th: Board of county
commissioners (BOCC) to determin" it lt should be referred to the Planning commission prior
to being heard by the BOCC. The Board decided not to refer the Application but also discussed
the possibility of these types of facilities being permitted in other zone districts and also possibly
as a Use-By-Right where appropriate. fo thit end, Staff has taken a broader approach to these
points as well a-s tf,e speciiic text amendment request by the Applicant'
II. CRMS PROPOSAL
The Applicant proposes to add the following use to the ARRD zone district as a special Use
and add its oeiinition to sectio n 2.0 of the county's Zoning Resolution:
solar Electric Power Generatinq svstPm. A ground-y.?y!t'.d photovoltaic power
generating system aesigned@mori thu, 50kW of energy consisting of
some, but not necessarily ail, oi the foilowing components.: Photovoltaic modules;
array support structures, including footers; power conversion/ inverler system; balance
of system components; aniitpfi, *a2nng ,?d monitoring equipment; acceptable
seruice panel ior consur", u"l" of phot-ovoltaic power; AC grid connection; and
securitY fencing.
Staff understands this use, as proposed by the Applicant, is meant to cover solar array facilities
that are large and commercial in nature that create electricity for a variety of consumers rather
than for personal use to power a single-family residence or principle use of a lot without
commercial gain. However, Staff suggests the definition may be too specific which may result in
being too restrictive because it is specific to the particular components on the proposed facility.
As an alternative, Staff suggests a broader definition as follows:
Solar Power Generatina Svstem. Also referred to as solar arrays, d device/
system which converts the sun's radiant energy into thermal, chemical,
mechanical, or electric energy. Such facilities are intended to create
electricity to be delivered to a variety of consumers beyond the facility and
are not constructed specifically for, or accessory to, the principal use of the
subject property.
Staff believes this definition provides a broader ability for a multitude / variety of systems that
may have varying design techniques to fall under this definition with the continued purpose of
allowing a system that is intended to create energy from the sun.
While the Applicant proposes a definition of the use and requests it be included as a Special
Use in the ARRD zone district, the Applicant did not suggest any standards / criteria that might
be used by Staff and the BOCC to evaluate a project in order to deal with any impacts
associated with a project of this type. To that end, the Board is required to address the following
provisions so that appropriate standards are also put in place for this use, if necessary:
A. The Application shall demonstrate how the proposed project will not impact
wildlife and domestic animals through the creation of hazardous attractions,
alteration of existing native vegetation, blockade of migration routes, use
patterns or other disruptions.
B. The Application shall demonstrate how the proposed project will impact truck
and automobile traffic to and from such uses and their impacts to areas in the
County.
C. That sufficient distances shall separate such use from abutting property which
might otherwise be damaged by operations of the proposed use(s).
D. The Application shall provide a plan for site rehabilitation after the use is
terminated.
E. The County Commissioners may deem necessary a financial security before a
land use permit is issued. The Applicant shall then furnish evidence of
financial security payable to, in a fashion acceptable, and in the amount
calculated by the County Commissioners. The financial security shall be
adequate to secure the execution of the site rehabilitation plan in workmanlike
manner and in accordance with the specifications and construction schedule
established or approved by the County Commissioners.
F. The Application shall demonstrate that the facility shall be able to comply with
the volume of sound standards set forth in the Colorado Revised Statutes.
G. The Application shall demonstrate that the facility shall be operated that the
ground vibration inherently and recurrently generated is not perceptible,
without instruments, at any point of any boundary line of the propefi on which
the use is located;
H. The Application shall demonstrate how the proposed facility will be operated
so that it does not emit heat, glare, radiation or fumes which substantially
inbrtere with the existing use of adjoining property or which constitutes a
public nuisance or hazard.
l. Any repair and maintenance activity requiring the use of equipment that will
generate noise, odors or glare beyond the property boundaries will be
conducted within a building or outdoors during the hours of I a.m. to 6 p.m.
J. Any lighting of the facility shall be pointed downward and inward to the
property center and shaded to prevent direct reflection on adjacent propefi.
K. Such facilities shall not result in any structure exceeding the maximum height
limit, setbacks, or lot coverage of the applicable zone district in which it is
located.
Based on these standards, Staff suggests that this use be allowed as a Special Use in
the following zone districts:
o 3.01 A/l--Agricultural/lndustrial. 3.02fuHlRD--Agricultural/Residential/Rural Densityo 3.O7 C/L--Commercial/Limitedo 3.08 C/G--Commercial/Generalo 3.09 O/S Open Spaceo 3.10 F/L--Resource/Lands (all sub zones)o $. 12 Ul-Light/lndustrialo 3.13 P/A--Public Airport. 3.14 Drinking Water Constraint Zone. 3.15 Commercial Water Constraint Zone
III. SOLAR POWER GENERATING SYSTEM FOR PERSONAL USE
Staff examined this use as it also applies to Solar Power Generating Svstem for personal use
such as solar panels on roof tops of individualsingle-family dwellings and / or principle uses of
a lot. Staff believes these types of facilities are non-commercial in nature and personalto the
use it serues on the same property. ln this case, Staff finds these facilities should be
3
considered as Accessory Uses / Structures to the Principle Use and would be a use-by-right in
all zone districts in the County. There may be building code requirements but no use
requirements. The Zoning Resolution already addresses this use as the following:
2.02.011 Accessoru Uses: lncident only to a lavvful use, any use, which
complies, with all of the following conditions may be operated as an accessory
use:
(1) ls clearly incidental and customary to, and commonly associated with a
lavvful use;
(2) ls operated and maintained under the same ownership and on the same lot
as the lavvful use;
(3) Does not include structures or structural features inconsistent with a lauvful
use; and
(4) Does not include residential occupancy except by domestic employees
employed on the premises and the immediate families of such employees.
As a result, Staff suggests that no action is necessary by the BOCC regarding these
personal facilities and that they would exist a use-by-right in all zone districts as accessory
uses / structures.
IV. COMPREHENSIVE PLAN LAND USE GOALS AND OBJECTIVES
The proposed text amendment is consistent with the following Objective of the Garfield
County Comprehensive Plan:
Objective: 2.4 The County should encourage the development of energy etficient
design, including solar access.
