1. Meeting called to order at 4:05 p.m.
2. ESLO Code Review Strategy
Mr. Vella explained that at today's meeting, PAC members would receive a 42-page ESL
Ordinance draft for review and discussion at the next meeting. Updated drafts will be
distributed in advance of future meetings. Today, the PAC will discuss the ESL Overview and
Purpose Statements.
Mr. Adler asked how"cultural resources" fits into this ESL discussion. Mr. Vella explained
that while the ESL PAC is working on all elements, the Historic Preservation Commission
(HPC) is addressing the cultural resources aspect. The ESL draft has a placeholder for
Cultural. Mr. Williams added that if the process is viewed as a flowchart, the HPC's cultural
resources work will parallel the PAC work on the rest of ESL
Mr. Adler said he was concerned because this body needs to review the HPC draft so that
both efforts have the same approach. The HPC measurements and definitions are different
than ESL. Ms. Davis said she agreed that we should review HPC's work, but that the
decision to work independently was made by the HPC Chair, who attended the first ESL TAC
meeting. Mr. Vella said that if the HPC work does not fit seamlessly with the ESL work, any
discrepancies will be addressed by staff and the consultant.
Mr. Adler said that the term "significant" has a federal definition that applies only to cultural
historic resources. Mr. Solomon asked if we have a definition. Ms. Davis said that we don't
have that now but we will, and Mr. Williams said that a definition could be included. Ms. Davis
said that a discussion on Cultural Resources will be included in a future ESL PAC agenda.

3. The First Draft: Delivery and Overview
Mr. Williams presented the PAC with the first draft of the ESL Ordinance and accompanying
materials, which he discussed and explained as follows.
• Table of Contents
o Section A, the intent of the Ordinance, is based on the County's Plan but
will be customized for Oro Valley.
o Section C addresses open space requirements.
o Section D addresses Use and Development Standards.
o There is a distinction between III (Regulations for Development under the
ESL Conservation System) and IV(Regulations for Development on ESL
with Zoning Prior to ESL Adoption)
o Section F, Maintenance and Violations, will include ways to ensure that
areas are protected.
• Table III -1 (Lists the amount of open space required under each category and in
what category the resources belong)
• Conservation Systems Categories (color table)—derived from ESL TAC
definitions, and based on Sonoran Desert Conservation Plan.
• 42-page ESL Ordinance
Mr. Solomon expressed concern that on the color table, rock outcrops are in the Critical
Resource area. Mr. Williams said that categories can be added or removed, as long as they
are in alignment with Town code. Mr. McKee said that rock outcrops are not in the Core
Resource Area Category.
Mr. Andrews explained that the discussion of these topic is not on the agenda. The draft is
for the PAC members to take away and review, so they can bring up questions and concerns
in future meetings. Ms. Davis said that we will need to be very clear in future agendas, to
ensure that we can properly discuss concerns. Mr. McKee said that the agenda items still
need to be broad. Mr. Andrews stated that agendas need to be specific as to what will be
discussed. Ms. Davis said that this discussion is a good first step.
Mr. Vella said that future meetings will be dedicated to specific topics such as "Applicability"
and "Conservation Systems," and we will have as many meetings as are needed. Mr. Adler
said that our meetings will need to be longer. Mr. Andrews offered to assist with agenda
drafting, and suggested that meeting end times be left open. Mr. Kline asked if the Town
could provide food at these longer meetings. Ms. Davis said light, simple meals could be
provided if we anticipate going past 6 p.m.
Mr. Adler asked if the ordinance will allow additions or code update amendments. Mr.
Williams explained that the draft of design standards is not yet ready for review, but assured
Mr. Adler that his earlier questions and concerns would be addressed. The intent is to revise
the ordinance within the limits of Proposition 207.
Mr. Adler referred to Section D3 (Design Tools and Incentives) said that incentives can still
represent an opportunity. Mr. Andrews said that if a project is being considered under
Section III, then it would be rezoning, and the issue would be what the Town can do as part of
a rezoning. Mr. Williams suggested that a faster, more efficient process could be created to
encourage rezonings.
Mr. Adler suggested that the Ordinance could include the use of administrative decisions, as
long as they are not used to circumvent the application process.

Mr. Williams urged PAC members to read and mark up the draft, and return comments to him
through Ms. Davis. Mr. Andrews reminded everyone to send emails directly to Ms. Davis or
her delegate and not to blind copy anyone. Another suggestion was to bring comments to
the meeting, and to review the document section by section. Mary agreed that concerns
should be brought up section by section, so they can be discussed and recorded.
Mr. McKee asked if the sequence or listing of what the PAC will be discussing could be
provided with the next agenda.
4. ESLO Overview& Purpose Statement
Ms. Davis explained that the Purpose Statement was derived from the PAC's input and the
language previously presented by staff to Council. She added that it was very important to
ensure that the Overview and Purpose Statement clarify ESL goals, and that they be in line
with the Sonoran Desert Conservation Plan.
Mr. Adler said that the drafts use language that doesn't exist in other places, and asked if we
intend to develop a glossary.
The PAC discussed the first sentence, and more specifically the word "critical", in the
Overview. Mr. Andrews suggested using the term "science-based." Mr. Adler asked why the
word "conservation"was included when it wasn't part of the PAC's Purpose Statement. Ms.
Davis said that the overview included some historical sequencing, and commented that we
don't want the entire document to be driven by the wishes and decisions of the Historical
Preservation Commission.
Mr. Williams said he was hearing that the use of the words "protection" and "critical" in the
Overview were viewed as suspect or troubling.
Mr. Solomon said that the term "community sustainability" may have different meanings. Ms.
Davis said that the term was used deliberately, but noted that it wasn't used in an
enforcement context. Mr. Andrews said it is okay to use broad phrasing like that and for the
meaning to change, and added that specific language is enforceable, whereas general
language is not.
(Meeting discussion was suspended while two PAC members took a short break and left the
room.)
The following changes to the Purpose Statement were proposed:
• Trim the section down (Mr. McKee)
• ESLS needs to be spelled out(Mr. Williams)
• Section II, 2a: Remove "so" (Mr. McKee)
• Section II, 1g: Replace "ensure"with "encourage" , (Mr. Solomon)
• Why use "system" instead of"regulation?" (Mr. Adler)— Mr. Williams said he views this
as an entire system, and is following the Pima County plan.
• Use ESL "Regulations" instead of"system" (Mr. Kline)
• Section 4b: refers to "peaks, ridges and highly visible slopes" but elsewhere it states
that these are outside of Town boundaries(Mr. McKee)
• Section 4: Use "preserve" instead of"conserve" or"protect" (Mr. Adler)
• Mr. Williams clarified that the PAC wishes to use "conserve" or"protect"
• Ms. Davis said that definitions would be introduced at the next meeting.
• Ms. Davis and Mr. Andrews stated that the use of the word "protect" can still be used
and is applicable in some form.
3
•
• Section 3a:
o Do not use the word "integrate" (Mr. Solomon)
o Replace word "unique"with more applicable term (Mr. Andrews)
• Section 6b: Statement that reduction of glare is "important to humans" is
questionable(Mr. McKee)
• Need to say that one purpose is to preserve cultural resources while still allowing
access (Mr. Adler) Mr. Williams suggested that"manage" might be a better term.
• Mr. Adler's use of word "balance" is good (Mr. Andrews)
• Section 8a:
o "Economic opportunities" may not fit into this discussion (Mr. McKee).
o There is a strong correlation between keeping land values high and maintaining
open space benefits (Mr. Kline)
• Overall, the language used is balanced (Mr. Solomon).
Ms. Davis asked the PAC members to email any additional thoughts to her by 5 p.m. Friday,
Oct. 29, , which she will then forward to Mr. Williams.
5. Review of October 15, 2009 Meeting Minutes
Minutes approved with no changes.
6. Future Agenda Items
The PAC will proceed to review the Ordinance draft by section, following the Table of
Contents. The next meeting will be at 4 p.m. (ending time will be left open) on Thursday,
November 12th, in the Hopi Conference Room.
7. Meeting adjourned at 6 p.m.

I. Environmentally Sensitive Lands (ESL)
Overview
The Environmentally Sensitive Lands (ESL) regulations are a biologically-based
systems approach to the protection and conservation of critical resources.
The Town of Oro Valley's General Plan establishes goals and policies for Sonoran
Desert Protection,Natural Resource Conservation and Cultural and Visual Resource
protection. These environmentally sensitive resources include wildlife habitat,
riparian areas, interconnected open space, significant vegetation, rock and boulder
outcrops, peaks, ridges, steep slopes, cultural resources and scenic corridors. This
ESL System (ESLS) is designed to bring together existing Town codes and regional
policies, providing a comprehensive structure for the Town's conservation categories.
The Town has mapped environmentally sensitive resources, and established a
conservation system based on scientific analysis, regionally adopted conservation
policy and relative resource values. In order to accurately and consistently apply the
ESLS, clear standards for defining, identifying and mapping these key resources in
the Town are included in the ESLS.
The protections for critical resources identified by the ESLS are based on five basic
tenets of current conservation biology:
• Perpetuating the comprehensive conservation of vulnerable species
• Retaining those areas that contain large populations of vulnerable
species
• Providing for adjacency and proximity of habitat blocks
• Preserving the contiguity of habitat at the landscape level; and
• Retaining connectivity of reserves with functional corridors.
The ESLS is designed to balance the public health, safety and welfare goals of the
community with agreed-upon biological, cultural, and visual priorities to create a
holistic system for protection and management of identified resources.
Implementation of the ESL System carries broad local and regional significance with
regard to community sustainability and the conservation of the sensitive resources
that endow the Oro Valley area, giving it a distinct and valued character.

II.Purpose
Theoal of ESLS is to identify and address the Town's natural and cultural resources
g
in a comprehensive manner. The preservation, restoration, and maintenance of
environmental resources require an integrated approach. The Town's open space,
biologically significant areas, scenic and cultural resources must be defined,
prioritized and addressed holistically, using clear, science-based criteria and
innovative methods while respecting property rights.
The Environmentally Sensitive Lands System(ESLS) is designed to achieve agreed-
upon preservation and conservation goals, in conjunction with protecting the public
health, safety and general welfare by:
1. Conserving the Sonoran Desert
a. Provide a holistic and systematic approach to resource conservation based
on the current science of conservation biology.
b. Understand biological systems function with a comprehensive focus on
interrelated resources and the need for landscape preservation connections
to ensure the continued viability of animal and plant communities.
c. Implement the vision of Pima County's Sonoran Desert Conservation Plan
for conservation of biological corridors, critical habitat and riparian areas.
d. Conserve Significant Resource Areas (SRAs) identified by the General
Plan.
e. Protect and manage environmentally sensitive open space areas.
f. Pro -_- ion for key and essential habitats.
t. Ensure %e long-term survival of the native plants and animals by
.. aining ecosystem functions necessary for their survival.
h. Preserve, salvage and replace native vegetation, to stabilize desert soils
and provide food and protection for desert wildlife.
i. Encourage the preservation of wildlife habitat and wildlife friendly design
through improved site design.
j. Preserve the Sonoran Desert landscape, including riparian areas and rock
outcroppings.
2. Preserving Land Values
a. Preserve the Sonoran Desert landscape and scenic views th, are critic.
to attracting residents and visitors.
b. Encourage riparian habitat conservation and in-place preserva i s n o
native vegetation, an integral part of the Sonoran Desert that enhances
property values, quality of life and community lifestyles.
3. Conserving Cultural Resource
a. Provi.- ; . -.ervation t T unique a► haeological and cultural resources
fr•' integrate - ith the co s- . . .• - of other significant resources.
b. • sn 'a- e potential effect of development on historical and prehistoric
resources.

c. Preserve exceptional resources in place, if possible, and develop
mitigation strategies when needed that preserve the Town's rich cultural
heritage.

5. Guiding and Enhancing Urban Design
a. Ensure interconnected open spaces.
b. Provide direction for site and building design to protect sensitive
• resources.
c. Use context sensitive design.
6. Promoting Living Quality
�►� a. Protect the visual resources identified by the General Plan.
b. Conserve natural open space areas that provide direct and important
physical and psychological benefits to human beings to reduce glare and
to break up the monotony and soften the harsher aspects of urban
development, while addressing community-wide natural resource
conservation goals.
7. Protecting lives and property
Protect human life and property from recognized hazards including steep and
unstable slopes and soils, flood and erosion hazards.
8. Supporting Sustainable Growth
a. Effectively apply comprehensive and systematic management and
conservation of sensitive resources. Application of ESL principles of
interconnected open space and resource protection and conservation
provide the best opportunity for holistically sustaining the resources that
create the quality of life and economic opportunities attributable to the
Town of Oro Valley. Applying the ESL Conservation System to
properties that are being rezoned and to properties desiring to develop
under existing zoning regulations serves to implement agreed-upon
community conservation goals.
b. Provide incentives to encourage property owners to utilize the ESL
Conservation System when determining preferred uses and specific
development designs for private property where environmentally sensitive
resources exist, thereby furthering conservation efforts.
c. Recognize and respect existing zoning standards and promote compatible
development utilizing best environmental management practices.
