SUBJECT: REVIEW OF UPCOMING WORK SESSION AND CITIZEN WORKSHOP:
ENVIRONMENTALLY SENSITIVE LANDS PLAN & ORDINANCE
BACKGROUND:
The Environmentally Sensitive Lands Project consists of two main components. The primary one is a new
consolidated Focus 2020 General Plan element, which is the vehicle to establish the vision, goals, and policies
of the ESL project. The Plan must clearly establish the direction or tone of the subsequent ordinance.
Ordinance objectives include identification, enhancement, and preservation of significant resources and
consolidation and simplification of existing ordinances.
Over the past year, staff and the consultants, Jones & Stokes Associates and Harris Environmental, have
collected an array of citizen and special interest input, land use data, field verified biological data, and guidance
through a Technical Advisory Committee (TAC) and very diverse Public Advisory Committee (PAC).*
Over the past year, staff has solicited input through the following mechanisms:
• Two Public Workshops
• Town Council Approval of Public Advisory Committee (PAC) & Technical Advisory Committee (TAC)
• Five Public Advisory Committee Training Sessions (Instruction Provided by Various Specialists)
• Eleven Public Advisory Committee Meetings (Each Noticed in the NW Explorer Town Page)
• Two Technical Advisory Committee Meetings
• One joint Commission and Council Study Session
• Distribution of 3,500 Random Surveys (28.1% Return Rate!)
• Stakeholder Meetings (NW Chamber of Commerce, Association of Realtors, SAHBA Technical Review
Board, Neighborhood Coalition, and Sun City Vistoso Community Association—Government Affairs
Committee)
• Direct Mailings to all of the Homeowner's Associations within the Town
• Meetings with other Jurisdictions with Similar Plans and Ordinances
• Provision of an Interactive Website (www.j onesandstokes.cornlplanloro-valley)
The team is nearing completion of a final draft. Our aim is to present the Plan to the Commission early in
August. Upon receiving a recommendation of approval, it will be scheduled for Town Council review.
WORKSESSION/WORKSHOP PURPOSE
The PAC primarily shaped the current draft. At this point, we are redoubling are efforts to broaden, again, the
spectrum of involvement. On July 13, 2000, a worksession and a public workshop have been scheduled in order
*Member list attached
TOWN OF ORO VALLEY
COUNCIL COMMUNICATION Page 2 of 3
to solicit specific comments regarding the Plan. The primary aim is to generate input from non-PAC members
to gauge whether the Plan reflects the broad spectrum of citizens concerns.
The evening will commence at 6:00pm with a joint Council and Commission worksession. Staff and the
Consultant will begin with a brief presentation aimed at educating the citizens in attendance and providing a
progress report to the Council and Commission. From 6:00pm to 7:00pm, the two bodies will have the
opportunity to ask questions and provide input. Please review the attached draft Plan. Specific comments
(verbal and/or written) are encouraged.
At 7:00pm, the public workshop portion will commence in earnest. Several professional booths and displays
will be staffed to encourage citizen input via one on one conversation. To help garner attendance,
approximately 11,000 postcard invitations were mailed by utilizing the Town water bill database. In addition,
brochures were mailed to the all of the HOA's in Town, surrounding jurisdictions, and various special interest
groups. Newspaper and television coverage is currently being arranged.
COMPONENTS OF THE PLAN:
The draft Plan is comprised of the following elements:
• Community Analysis and ESL Process
• Community Survey
• Identification of Strengths, Weaknesses, Opportunities, and Threats
• Open Space Resources, Issue Identification, and Policies & Recommendations
• Biological Resources, Associated Maps, Issue Identification, and Policies & Recommendations
• Visual Resources, Issue Identification, and Policies & Recommendations
• Water Resources, Issue Identification, and Policies & Recommendations
• Cultural Resources, Issue Identification, and Policies & Recommendations
• Air Quality Resources, Issue Identification, and Policies & Recommendations

SUMMARY
From the start of the Plan effort, staff has solicited input via a broad spectrum of venues. Over the past six
months, the PAC and TAC have been a primary source of input. In fact, the PAC has reviewed each of the
elements, except Air Quality, one at a time. We have also had two marathon PAC sessions whereby the Plan
was reviewed in its entirety. Now that we are close to finalizing a draft, our primary goal on July 13 is to
reinvigorate an even broader spectrum of involvement. Our focus is to solicit specific comments to incorporate
into the Plan, which will guide the formation of an Ordinance.

design considerations, has the opportunity to f� 7, �x
achieve an integration of desirable residential
and employment growth while protecting its
environmental assets.
Climatic variations, especially temperature extremes and rainfall intensities, are natural conditions that have
shaped Oro Valley's environment. Sonoran Desert communities have adapted to, and in fact thrive in, these
harsh conditions; however, removal and destruction of habitat can occur through unwise or uncontrolled
building and excavation practices.
Protecting the area's natural attributes has been designated by the citizens and Town officials as a high
priority among Oro Valley's planning objectives. All other Plan elements, as they are implemented, must be
sensitive to the overriding desire to conserve the quality of these resources.
In order to provide for this comprehensive assessment and treatment of environmentally sensitive lands, this
element has been designed to address issues related to open space, biological, visual, water, and cultural
resources. To guide the development of this element, the Town has adopted the following vision statement.

4.8.2 Existing Conditions
Spectacular mountain backdrops of the Santa Catalinas and Tortolitas frame the Planning Area. Oro Valley
enjoys the scenic attractiveness of mountain views and vistas. Largely contained in federally and state-owned
protected mountain preserves,the Town is assured of the natural backdrop provided by these mountains(under
current federal and state policies).
Foothills,forming an undulating and less rugged apron of landforms,can be more easily developed and are a
greater conservation concern. Developments on erodible steep slopes,highly visible from within the Town,can

sensitive to the visual environment.
Occupying the majority of the Town,the desert"flatlands",interspersed with washes and usually dry riverbeds,
form the groundplain where most activity occurs. The valley floor supports several unique plant communities,
such as the Ironwood Plant Community(west of La Cholla and North of Magee Road)and mesquite bosques
along the edges of floodplains and washes with associated animal communities. These biotic associations
encourage high species diversity and food chain interdependence that should be better understood,and then
protected through regulations.
The Town of Oro Valley owes much of its attractiveness and development appeal to the abundance of its natural
resources. These resources,however,must be thoughtfully managed by the Town to achieve its maximum long-
term potential and retain its well-known character.
Located in the heart of the Sonoran Desert,Oro Valley must cope with a limited water supply. Relatively low
precipitation, 15.48 inches(average)per year,and high dissolved mineral content in the water are contributing
factors to water quality and supply issues. Even with these limitations,Oro Valley is fortunate to be located in
the special water service area of the Central Arizona Project;thereby virtually assuring the Town of adequate
water supplies to support expected growth. The Town's water-related policies are intended to support water
resource stewardship.
Recent residential developments,in addition to being served by municipal water supplies,are connected to sewage
treatment facilities. The wastewater treatment plants provide an opportunity to conserve valuable water supplies
through reuse of treated wastewater. Properly designed recycling systems should be allowed for individual
residences and Planned Area Developments(PADs)to reduce water usage. The Town should also encourage
economic,regulatory,and voluntary water conservation practices.
Clean,clear air has always been a hallmark of Oro Valley and has attracted thousands of residents seeking
freedom from allergies. However,with increased urbanization and reliance on private automobiles for
transportation,and increased planting of non-native species for landscaping,higher amounts of suspended
particulates and higher pollen counts has become a reality.
Air quality concerns are most effectively addressed at the local level through Town-adopted design standards that
can limit undesirable species of plant materials or restrict fossil fuel burning,and through
transportation/circulation policies that encourage reduced emissions through conservation practices and
emphasize mass transit services. Regional air quality solutions are encouraged that would also benefit Oro
Valley.

A. Community Analysis
For any plan to be successful,it must reflect the input and desires of the public. In the development of this
element,public input was sought through public workshops/hearings,involvement by citizens in a series of Public
Advisory Committee(PAC)meetings,and through input collected using a community survey.
Community Survey
In August of 1999,a survey was mailed to 3,500 property owners(selected at random)in the Town. Of the
surveys mailed out,984 responses were received(over 28%). This was an excellent response rate to a mail
survey,and provides a good overview of the desires of citizens in Oro Valley.
In general,the survey set out to gather input on:
• What are considered to be sensitive environmental resources of importance?
• What types of restrictions should be used to protect sensitive environmental resources?
• How do current Town ordinances do in protecting environmental resources?
• What are some techniques that can be used to protect sensitive environmental resources?
• How should protections be paid for?
• What types of uses are appropriate in environmentally sensitive areas?
The first question posed in the survey asked respondents to rank a list of resources in order of importance to them
(with"1" being the most important and"10"being the least). In ranking responses,the order selected is as
follows.
Question 1
1. Groundwater 5. Native plants
2. Scenic views/vistas 6. Desert wash areas
3. Open space 7. Geologic formations
4. Wildlife habitats 8. Archaeological/historic
The second question stated that the Town had ordinances to address hillside development,archaeological sites,
riparian protection,and native plants,but don't include the protection of other environmental resources. On a
scale of 1 (strongly agree)to 5 (strongly disagree),there was good support for adding open space,scenic
vista/view regulations,geologic formations,and wildlife habitat.
Question 2
Open space 1.6 average score
Scenic vistas/views 1.7 average score
Geologic formations 2.2 average score
Wildlife habitat 2.0 average score
Revised: 6/20/00(Workshop#3,ESL Plan 10) Page 3 DRAFT General Plan Element(Electronic Version)
The third question asked respondents to evaluate the performance of existing Town ordinances based on recent
projects. In every case,the average response was that the ordinances worked"in some cases". The interpretation
of this is that there is room for improvement in the protection of environmentally sensitive resources. It should be
noted that the Town recently adopted a revised native plant ordinance.
Question 3
Hillside development 3.1 average score
Archaeological sites 2.7 average score
Riparian protections 3.0 average score
Native plant salvage 2.9 average score
In Question 4,the survey asked respondents to select from a range of techniques that could be used by the Town
to protect resources. The survey showed a need for new regulations and a general support for policies that
reduced the amount of development. The concept of smaller lots with open space was not widely supported,
although the concept of clustering is not well known in the public. The final two items related to costs(who
pays),with an increase in development fees being favored over the Town purchasing development rights
(although this may apply in some cases).
Question 4
No new environmental regulations 3.4 average score
Tax incentives to retain open space 2.6 average score
Allowing smaller lots w/open space 3.4 average score
Reducing residential densities(large lots) 2.1 average score
Requiring open space dedications 1.9 average score
Raising development fees to finance 2.0 average score
Town purchase of development rights 2.5 average score
The next question stated that some land preservation techniques might involve the Town purchasing land or
development rights,and asked individuals if they would support an increase in sales tax rates,a bond measure,or
a property tax increase. The data below shows respondents are about equally split between those for and against
increases in sales taxes and new bonds to pay for some preservation techniques. On property taxes,the majority
fell on the"No" response. Regarding potential amounts,there was not a clear direction given. In assessing these
responses,there are two caveats that could affect the responses. First,without a good understanding of what will
be purchased with an increase,public support is typically low. Second,there is likely to be a lack of knowledge
on the impact the amounts listed would have on Oro Valley(i.e.,how much money would a 1/4 cent sales tax
increase raise,and is this a significant amount).
Question 5
Sales Tax Bond Measure Property Tax
48.2% No increase 46.3% No 65.5% No
28.6% '/4 cent 22.0% $10 million 16.8% $25/house
18.4% '/2 cent 12.6% $20 million 5.2% $50/house
9.9% $50 million 7.0% $100/house
Revised: 6/20/00(Workshop#3,ESL Plan 10) Page 4 DRAFT General Plan Element(Electronic Version)
Question 6 asked if an interim ordinance or fix should be prepared to protect resources while this plan and
associated Environmentally Sensitive Lands Ordinance was being prepared. This concept received a fair level of
support,and changes to the Riparian Ordinance map were prepared.
If environmentally sensitive lands are designated,Question 7 asked what types of activities would be appropriate.
Overall,the uses that people wanted tended to be more passive in nature,with active recreational uses getting
lower support.
Question 7
Yes No Activity
- • Undeveloped/undisturbed open space
• Habitat/species protection
• • Horseback riding
• • Multi-use trail(paved)
• Golf course
• Habitat restoration
• Hiking
• Mountain biking
• Campgrounds
• Park/recreation facility
The final question on environmental resources asked people to name the top three locations for scenic views,
natural resources,and cultural resources. The results of this question are shown below.

B. Open Space
The Parks,Open Space,and Recreation Element of this General Plan contains existing conditions information
and goals,policies,and implementations designed to provide for a range of active and passive recreational
opportunities. This includes the provision and use of open space areas for trails and the enjoyment of the natural
environment that is prevalent in the Oro Valley area. For open space,the ESL Element enhances the Parks,Open
Space,and Recreation Element by providing additional guidance on the use of open space areas that also have a
high value as an environmentally sensitive area.
As shown in the Parks,Open Space,and Recreation Element,the Town's open space areas are primarily
comprised of larger wash areas and surrounding regional open space resources. These regional resources include
the following.
• Tortolita Mountain Park. Located adjacent to the northwest corner of the Town,Pima County
maintains over 3,000 acres of undeveloped open space that is a favorite for outdoor recreation.
Revised: 6/20/00(Workshop#3,ESL Plan 10) Page 6 DRAFT General Plan Element(Electronic Version)
• Santa Catalina State Park. This state park is located east of Oracle Road at the north end of Oro
Valley. This 5,500-acre high desert park includes limited camping(48 camping spots),picnicking,bird
watching,and multi-use trails.
• Coronado National Forest. The Coronado National Forest,managed by the U.S. Forest Service,
includes almost 1.8 million acres of land in southern Arizona. This National Forest includes the Pusch
Ridge Wilderness Area(53,933 acres),portions of which are located adjacent to the eastern border of
Oro Valley. Recreation opportunities include camping,hiking,multi-use trails,birds/wildlife viewing,
historic and prehistoric cultural resources sites. The Santa Catalina Ranger District is the district next to
Oro Valley,and includes 200 miles of multi-use trails.
C. Biological Resources
Oro Valley is located in a part of Arizona containing rich ecological resources in the form of diverse biological
communities supporting a wide variety of plants and animals. Oro Valley residents recognize that these resources
are a highly desirable part of the Town,and an important part of the Sonoran desert ecosystem.
In late 1999,a reconnaissance survey of the Town was conducted to identify habitat types that exist in the Town.
This resource inventory was the first step toward identifying sensitive biological resources,connections and
corridors between habitat areas,sensitive habitat types and locations,buffer areas needed to protect these
resources,and the most appropriate strategies for protecting,enhancing,and managing these resources.
The inventory focused on three areas:
• Riparian Plant Communities. Riparian communities were previously mapped in 1995. The most
recent inventory updated this data and mapped portions of the Town that were not included in the 1995
survey.
• Upland Vegetative Communities. Areas of predominantly native vegetation were mapped and
classified. Areas containing significant stands of ironwood and saguaro(defined as areas with more than
five individuals per acre averaged over five acres)were also mapped.
• Other Biologically Significant Features. Other features that have biological significance were mapped.
These features include mineshafts,caves,and rock outcroppings.
Table 2 summarizes the results of the biological resources survey. This table also shows the habitat that is
projected to remain once lands that are considered"committed"are removed from the total. For this study,a
parcel was defined as"committed"if it had:
• Parcel Number,Improvement($10,000 or up),Address
• Parcel Number,Improvement($10,000 or up),No Address
• Parcel Number,No Improvement($0),Address
• Parcel Number,Some Improvement(less than$10,000),Address
• Plans for Building(plans submitted to Town for consideration)
Revised: 6/20/00(Workshop#3,ESL Plan 10) Page 7 DRAFT General Plan Element(Electronic Version)
A parcel was defined as "Uncommitted"if it had:
• No Parcel Number,No Improvement,No Address
• Parcel Number,No Improvement,No Address
• Lack of plans for Building
On Table 2,three habitat modifiers are also shown. Areas with significant stands of saguaro or ironwood or with
significant rock outcroppings are important for the biological make up of the Town. These areas are mapped as
overlays of the habitat types shown on the top of Table 2.

sensitive lands(defined as essential habitats under Goal BIO.2).
D. Visual Resources
The Town of Oro Valley has a distinctive scenic quality as a result of three primary factors: native vegetation,
open space,and scenic mountain vistas.
• Native Vegetation. The Town of Oro Valley and the surrounding area contain an excellent example of
the richness that can be found in the Sonoran desert. In this area,upland habitats include a diversity of
plants that provide visual interest at both a distant and close in perspective. Signature saguaro and
ironwood stands are especially dominant in the views of the community. Within this desert setting,
riparian vegetation within the numerous washes that thread through the community also plays an
important role in defining the community's natural beauty.
• Open Space. In defining the visual character of the Town,the existence of open space is critical.
Existing open spaces provide a natural feel to the community and provide for views of the visual assets in
Revised: 6/20/00(Workshop#3,ESL Plan 10) Page 8 DRAFT General Plan Element(Electronic Version)
the community. Natural washes play a critical role in the Town's open space by providing for view
corridors and scenic beauty.
• Scenic Mountain Vistas. When looking around in Oro Valley,it would be difficult to find locations
where the surrounding mountains do not form a backdrop that frames the community. To the east of Oro
Valley,the Santa Catalina Mountains are a dominant visual feature. Within this range,and immediately
adjacent to the community,is Pusch Ridge,an exposed mountain ridge that is considered by many as the
defining physical feature of the community. This ridge is even the centerpiece of the community's Town
seal. Looking to the north and northwest,the visual backdrop is formed by the Tortolita Mountains. To
the west,many can see the Tucson Mountains,especially at sunset.
E. Water Resources
In the arid desert environment where Oro Valley is located,water is a limiting resource. Local surface water
provides drinking water for wildlife and establishes riparian corridors that support a wide range of plants and
wildlife. Groundwater resources provide drinking water for the Town and support seeps and springs that are vital
to local plants and wildlife. Protection and maintenance of riparian corridors and groundwater recharge areas is
important to maintaining the water resources and biological resources remaining in the Town.
A network of natural drainages exist as part of the landscape of Oro Valley in the form of ephemeral desert
washes that convey runoff in response to periodic rain events. Two major washes in Oro Valley,Ca•ada del Oro
and Big Wash,are large regional washes that periodically convey large volumes of runoff.The remainder of the
undeveloped portion of the Town is covered with a network of washes of varying width and depth that provide
surface drainage generally toward the south. The desert washes in Oro Valley support a network of ecologically
valuable riparian habitat that is directly linked to the natural drainage regimen that is in place in undeveloped
areas. These washes also provide opportunities for runoff to percolate into the groundwater aquifers underlying
the Town.
Oro Valley depends on a network of municipal and private wells that pump groundwater for domestic use. These
wells are located throughout Oro Valley. Although Oro Valley has an assigned allocation of water from the
Central Arizona Project,this water is not currently used due to a lack of infrastructure.
In areas where development has occurred near natural drainages,these features have typically been altered.
Depending on the individual project designs,the natural washes have either been completely removed by grading
and installation of drainage systems,or have been partially incorporated into the site plan. For these projects,
partial preservation of the wash system,while ecologically preferable to total removal,has typically altered
drainage patterns to some degree and impacted natural vegetation communities.
Because water resources are interrelated with riparian habitat,this section will focus specifically on water as a
separate resource,while the biological resources section will address the riparian habitat associated with the wash
system.

c.3}
The Town of Oro Valley is located in an area that bears remnants from a multi-layered cultural heritage. These
remnants range from the native cultures that resided on or traveled through these lands thousands of years ago to
Euro-American cultures that established themselves in the American West during the more recent historic period.
Oro Valley citizens recognize the value of these cultural remains and encourage opportunities to protect and learn
about this heritage.
During 1999,a cultural resources sensitivity analysis was performed to determine how much is known about the
Town's cultural resources. This analysis also classified areas with regard to relative sensitivity for prehistoric and
historic resources. The analysis was based on a comprehensive search of survey records from various agencies
and a review of site records for documented cultural resource sites. From the 41 cultural resource surveys
projects undertaken in Oro Valley,92 historic and archaeological sites have been identified within the Town.
These known sites are predominantly associated with the Hohokam culture(86 sites),with the remaining six sites
considered historic sites associated with the late 1800's and early 1900's. Using this information,an evaluation
of cultural resources sensitivity for the Town was prepared.
Survey data suggests that four sections in the northwestern portion of Town and a portion of another section on
the western portion are the most sensitive. However,this perceived sensitivity may be due in part to the relatively
large number of surveys that have been performed in those areas,though the area may also contain village sites
that add to the potential sensitivity. Conversely,areas that appear to have low sensitivity have had fewer surveys.
G. Air Quality
The PAC recently requested that an Air Quality section be added to this document. This section is currently
under development.
4.8.3 Issue Identification
The following section lists some of the critical issues that must be addressed in implementing this element of the
General Plan.
A. General Issues
• Funding for Acquisition of Open Space Lands. The Town needs to establish a funding
mechanism for the acquisition and management of open space lands. Without timely establishment
of such a mechanism,the Town will continue to develop and further limit options for establishing a
connected system of open space.
Revised: 6/20/00(Workshop#3,ESL Plan 10) Page 10 DRAFT General Plan Element(Electronic Version)
• Open Space Tools. The Town needs to develop a wide-range of planning tools that can be used to
acquire,protect,and enhance the environmentally sensitive lands that help define the community's
character.
• Connectivity of Environmentally Sensitive Lands. The Town needs to ensure that connections are
maintained for ecosystem function and the movement of wildlife.
B. Open Space
• Lack of Integrated Open Space Areas. Additional open space lands need to be set aside for use by
the general public before ongoing development of Town further reduces or limits options for open
space planning.
• Connectivity of Open Space and Recreational Areas. Open space needs to be established with
consideration given to establishing connections with other open space and recreational areas within
the Town and adjacent lands.
C. Biological Resources
• Steady Loss or Degradation of Biological Resources. Development in Oro Valley has directly
affected the quantity and quality of natural resources. Unless something is done,a steady loss of
native habitats will continue.
• Fragmentation of Habitat. As the amount of developed land increases,habitat areas are becoming
fragmented,reducing the ecological value of these areas.
• Compatibility of Development with Biological Resources. Some projects constructed in Oro
Valley do not take into account the sensitive resources affected by the project. Adequate buffering is
not often taken into account,and has resulted in impacts on biological resources such as constraints
on wildlife movement,impacts on wildlife from urban lighting,and erosion into riparian corridors.
• Restoration of Degraded Habitat. Some areas within the Town once contained high value habitat
that has subsequently become degraded for a number of different reasons related to human activities
within the Town. These areas may provide excellent opportunities for environmental restoration.
D. Visual Resources
• Increases in Light and Glare. Increasing development will add to the amount of light and glare
within the community. This will result in loss of nighttime sky visibility.
• Protection of Hilltops,Ridges,and Slopes. Areas with higher topography,such as hilltops,ridges,
and slopes,are highly visible from many areas in the community,and development in these areas
could result in changes in the visual character of the Town and loss of significant topographic
features.
Revised: 6/20/00(Workshop#3,ESL Plan 10) Page 11 DRAFT General Plan Element(Electronic Version)
• Limit the"Sea of Rooftops" View. Design standards and restrictions are needed to keep
development from creating undesirable views,often referred to as a"sea of rooftops".
• Protect Scenic Corridors. Many roadways in the community provide views of scenic vistas,
washes,and native vegetation. The open feeling along some of these roadways also adds to the
character of the community.
• Maintain the Visual Character of the Community. Maintain the existing visual character of the
community. Look at issues related to placement or limits on aboveground utilities.
E. Water Resources
• Impacts to the Natural Drainage and Recharge System. Development activities in Oro Valley
have adversely impacted the natural wash system in the past and should be regulated.
• Use of CAP Water. Oro Valley should build a conveyance system to make use of Central Arizona
Project(CAP)water in order to reduce the use of groundwater resources.
• Use of Treated Wastewater. Treated wastewater should be used where appropriate for
groundwater recharge and irrigation.
• Protection of Wellheads. Wellheads for domestic water could be adversely affected by
development activities occurring in close proximity to well sites.
F. Cultural Resources
• Loss or Damage of Cultural Resources. As demonstrated by past survey work,Oro Valley is
located in an area that may contain significant cultural resources that could be permanently lost or
damaged during development. Regulations need to be developed to preserve significant resources.
• Defining the Significance of Cultural Resources. Cultural resources discovered during surveys
range from small insignificant finds to important cultural sites. The Town needs a standard of
significance to be used for managing cultural resources.
• Education Opportunities. Significant cultural resource sites provide an unparalleled opportunity
for the community to learn about its past.
• Interpretive Cultural Elements. Significant prehistoric and historic sites should be considered for
preservation as interpretative elements that can be accessed and used by the community for purposes
of education about past cultures.
G. Air Quality
The PAC recently requested that an Air Quality section be added to this document. This section is currently
under development.
