Santa Fe County, New Mexico is known the world over for its beautiful scenery and
unique landforms. Generations of artists have lived or painted here. People of all
walks of life have vacationed here. But the beauty of the County's landscapes can
be degraded if care is not taken. There are things a community can do to ensure it does not
lose its scenic beauty. A first step is knowing which places and things the community
thinks are important. That was the purpose of this project.
This report presents the results of that project--a visual resources inventory and
analysis of Santa Fe County. The study relied on both public and expert evaluation
in identifying areas within the County that have significance for visual reasons.
The study was initiated by the County because of widespread concern for the loss of scenic
quality in the County.
Why examine visual quality in the County?
Some may wonder why visual quality should be examined at all because it seems like
such a subjective undertaking. But County residents have expressed concern at the
degradation of beautiful places due to development. The quality of life for citizens
of Santa Fe County is defined, to a large degree, by the scenic nature of the place where
they live and work. Conservation of the important visual resources and sensitive
scenic areas is critical to the maintenance of this quality of life.
Process
The overall process used to assess visual quality combines extensive public input
with computerized map manipulation within a geographic information system (GIS).
The process began with an extensive photographic reconnaissance of the entire County
to record the full range of landscape types. These photographs are sorted and categorized
into landscape types. These types were then presented to the public for ranking of their visual quality. Rankings were subsequently used to create a map that shows
the average public value held for each typical landscape type.
The scenic influence of each landscape type was then rated for potential influence
on every other landscape type. These ratings were then used to modify the visual
quality rankings. Without this modification, aspen forests throughout the County
would have the same scenic quality. In fact, aspen forests adjacent to mountain creeks or coniferous
forests should rank higher scenically than aspen forests next to utility corridors
or roads.
A separate public nomination of special places helps create a complementary map of
those landscape features that are unique and would not necessarily show on a map
of typical landscapes.
Taken together, these two maps -ranking the visual quality of both typical and special
places--paint a comprehensive visual assessment of the County. The maps also provide
a framework for further computer analysis of visual sensitivity.
Detailed Process Description:
The following describes the specific steps that were carried out in assessing the
visual quality of Santa Fe County. For each step a description is given of what the
task involves, why it was undertaken, and what resulted.
A. Photographic Reconnaissance
of Study Area
Photographs of Santa Fe's landscapes play an important part in the analysis process
because they are something that the public readily identifies with and because the
categories they represent can be mapped.
A.1 Typical landscapes throughout the study area were photographed.
We conducted a county-wide field survey to begin the process of classifying the broad
Santa Fe landscape into categories of typical landscapes that in turn could be mapped.
Hundreds of photographs were taken throughout the County.
A.2 The photographs were sorted into logical, consistent categories.
The photographs were sorted into distinct groups, that could be used to represent
the entire County. Through this process, twenty-six landscape types were identified
and later refined with the assistance of the working group.
A.3 The categories of typical landscapes were reviewed and revised with locally knowledgeable
persons.
A working group of citizens was organized to advise the project. (The group represented
a wide range of interests from across the county. The working group commented on
the proposed methodology prior to initiating this study, as well as acting in a review
capacity at critical stages throughout the project.) The group reviewed and helped
revise the names used for landscape types so that they would be intelligible to the
public. (The names of members of the working group may be found in the Appendices.)
Local review of the category names was important to make certain the terminology being
used would be readily understandable to the public. Adjustments in category names
were made and English/ Spanish pairs were used when possible. At the end of the task,
photographs with category names were in-hand.
B. Data Base Creation
A computerized geographic information system (GIS) was used to map scenic resources
across the entire County. A GIS is an efficient and rapid means of creating and analyzing
maps of the entire area of the County. Such a system can also be updated quickly
and its maps recombined easily.
B.1 Create geographic information system with data layers capable of describing the
visual aspects of the study area.
A computer data base was created to carry out the mapping of the primary visual components
of the landscape so they could be used as part of the visual assessment process.
Some of these data, such as locations of roads and other built features, were readily available in the County's existing geographic information system. Other data, such
as land cover and elevation, were obtained from a variety of other sources.
The following data layers were
created:
Vegetation (Figure 13.)
The State of New Mexico provided a map of vegetation that was based on a Landsat image.
Mr. Tom Budge of the New Mexico Gap Analysis project, in providing the data, noted
that this data set had been classified, but not yet extensively field verified. This
data set was particularly important in describing land cover of the undeveloped areas
of the County.
Land Use (Figure 14.)
U.S. Geological Survey land use/land cover information was used for this study. These
data gave specific land uses for the developed areas of the County, uses, such as
commercial development, that may not be directly discernible from satellite imagery.
Elevation
U.S. Geographical Survey digital elevation models (30-meter supplemented with 90-meter
resolution where necessary) were combined to create a continuous terrain model. These
data are used in calculating viewsheds and slopes.
Natural and Built Features
County data were used for locations of such features as roads, streams, lakes, and
canals.
Existing Conditions Map (Figure 15.)
As a tool to help participants visualize the landscape of Santa Fe County, an existing
conditions map was created. This is an illustrative map that depicts land forms as
a colored, shaded relief (based on the elevation data) and has roads, streams, lakes
and canals overlaid for reference.
B.2 A base map was produced for public use.
The process depends on public comment and nomination of special places. The base map
needed to have enough detail and reference points that people could mark the features
they wanted to. A base map was prepared for public meetings and survey.(A copy of
the m map survey may be found in the appendix.)
C. Public participation was used to document public values
As a significant portion of this evaluation process depends on public values for rating
scenic quality, a means of assessing those public values was devised that would yield
both the quality and quantity of response needed.
There were two rounds of public meetings for the project. The first round was held
at seven locations across the County. (Meetings were held at Santa Fe, Tesuque, Chimayó,
Eldorado, Edgewood, La Cienega, and Pojoaque.)
C.1 A public survey was administered which solicited (on the base map) the locations
of scenic places, important view points, view corridors (e.g., scenic highways),
and viewsheds.
The survey (See Appendices.) was administered in two ways. First it was inserted in
the New Mexican and East Mountain Telegraph newspapers, made available through several
post offices and markets in the northern valleys, and given to all County employees
with their paychecks. Approximately 16,000 copies were distributed in these ways. One-hundred-thirty
copies were returned. Secondly, it was used at the first round of public meetings.
The process depends on knowing the locations that the public considers to be scenic
or important viewpoints or view corridors.
C.2 The public rated (from least to most scenic) each of the typical landscape categories.
At the first round of public meetings, participants were asked to rank the visual
quality of the landscape types. Using slides and photographs of a representative
image of each type, participants were asked to rate each type on a scale between
most scenic to least scenic (Figure 16).
To use public assessment of scenic quality there has to be a consistent rating system
so that an average rating can be reached.
The participants at the meetings seemed to have little difficulty ranking the 26 categories
of typical landscapes. There was little or no comment on the names used for the categories.
C.3 The public rated (from least to most compatible) the overall scenic quality that
would result when each landscape type occurs with each of the other categories.
In the final exercise of the first round of meetings, participants evaluated the effects
of one landscape type on adjacent landscape types. Using a matrix that had all landscape
types on one axis and all potential adjacent types on the other, participants evaluated whether a potential relationship would be visually positive or negative.
(Figure 17). Each respondent's evaluation was documented.
Scenic quality may be reduced when something that is beautiful is next to something
that is not. This exercise allowed the public to evaluate these kinds of relationships.
The matrix required considerable time to complete (20-30 minutes) and there were some
comments made about the unlikely occurrence together of several of the categories
of landscape. Participants rated the relationship between all possible combinations
of the 26 visual character types and each response was recorded as follows: Positive visual
relationship between types = +1, Neutral relation = 0, and negative visual relationship
= -1.
C.3 The results of the analysis were presented to the public for comment.
This allowed the public to see reported back to them what resulted from the first
round of workshops and public input. This allowed for a very helpful critique of
the conclusions of the earlier results.
The earlier way that visual sensitivity was calculated was vigorously questioned by
some residents of areas that they felt were sensitive, but the maps showed as not
especially sensitive. This caused the maps to be reexamined and reconfigured.
D. Scenic quality analysis based on
public values
D.1 Consolidate and digitize the publicly
nominated scenic areas.
To be used in the GIS the publicly nominated places had to be digitized. The map provides
locations for two landscape types: sacred places and unique landforms and features.
(Figure 4)
D.2 The public ratings of the scenic
quality of the typical landscape categories were averaged.
All of the participants' scores were averaged to compute a County-wide average and
to be able to assign these average values to each category and ultimately to map
these values.
The resulting County averages are shown in Table 4, sorted from most scenic to least
scenic. They portray a high level of scenic quality for the mountain backdrop of
the Sangre de Cristo Mountains, unique land forms and features, Rio Grande Valley,
the traditional irrigated valleys, canyons, aspen forests, the desert mountains, sacred places
and mesas. Commercial areas, utility corridors, surface mines and industrial areas
were considered the landscapes types with the lowest scenic quality.
D.3 Typical landscape categories were mapped.
Using the data layers in the geographic information system (vegetation, topography,
land use and the public nominated special and unique places), the twenty-six typical
landscape categories were mapped for the entire county (Figure 18).
This is a very important map in the visual assessment process because it is an intermediate
between the landscape types (reality)--photographs of which the public can readily
relate to--and abstractions of the landscapes--computer maps.
D.4 The Scenic Quality map was recategorized using the County-wide scenic quality
averages.
This step converts an inventory map (of landscape categories) into a map that shows
public values for intrinsic scenic quality (Figure 19). Visibility is not part of
this mapping exercise, that issue is addressed later in the process.
D.5 The public ratings of relational scenic quality were averaged.
An average of the public ratings allows these values to be mapped and therefore integrated
into the assessment process.
The list of the resulting values is very lengthy. Table 5 shows the most positive
relationships that exist in the County. When these landscapes are seen adjacent to
one another, the scenic quality is improved because of the relationship between each
type.
D. 6 Relational scenic quality of the study area was mapped to show the influence
of adjacent scenery.
This map was created so that the effects of adjacent scenery could be considered in
the map analysis. (See Figure 20.)
D.7 Scenic Quality and Relational Scenic Quality maps were combined to map overall
scenic
quality.
This step produces the final scenic quality map by modifying the initial map with
the relational ratings, giving a map that represents two aspects of scenic quality
(Figure 6).
The relational scenic quality map modifies the intrinsic scenic quality map by shifting
its values in a positive, neutral, or negative direction. When these two maps are
combined, the relational scenic quality map has the potential of affecting specific
areas by as much as 20 percent of the values assigned to the Intrinsic Scenic Quality
Map. For example, an area that had a value of 3.44 on the intrinsic scenic quality
map, may have specific areas enhanced due to a very positive adjacent use to make
that area's new value as much as 4.44; or by a very negative visual relationship, lowered
to 2.44.
The areas on the influence map do not correspond directly to landscape character type
units, since it is the edges of adjacent uses that are affected by this computation,
thus areas on the composite scenic quality map are not directly compatible either.
The resulting values from combining the general scenic quality map with the influence
map represent a ranking of scenic quality, from the highest to the lowest for the
entire county.
Highlights of Scenic Quality Map by quadrant:
Northwest Quadrant
The Rio Grande Valley received one of the highest scenic quality ratings in the
County. This area is one of the icons of the County (along with the Sangre de Cristo
Mountains) and is a tremendous visual resource.
Northeast Quadrant
Industrial, commercial areas, which are scattered through the City of Santa Fe and
along highways, are generally of very low scenic quality.
The traditional irrigated valleys of Santa Cruz and Nambe/Pojoaque are of high scenic
quality on this map and received considerable mention through the public process.
Southeast Quadrant
The very extensive area that extends south from the intersection of Highways 41
and 285 has a great deal of visual variety, with a mixture of open and wooded areas.
Southwest Quadrant
The mountains in the southern part of the County--the Ortiz, San Pedro, and South--are
of very high scenic quality.
Mining in the Ortiz Mountains has created an area of very low scenic quality at
the edge of an area (the mountains) of extremely high quality.
E. Visual sensitivity analysis based on expert judgment
Some parts of the Santa Fe landscape are more visually prominent than others. Specific
hillsides, fields and valleys are seen by large proportions of the population, while
other parts are only rarely seen. Those parts that are seen most often have the highest visual sensitivity, while those areas not seen are considered to have low visual
sensitivity. While all the characteristics of this perceptual phenomena are complex,
the primary factors are visibility from major viewing points, distance from viewing
points, topographic influence, and land cover influence.
E.1 The publicly nominated view points and view corridors were consolidated and digitized.
This step brings together all of the locations suggested by the public and puts them
into a digital form that can be used in the GIS. (See Figure 4.)
E.2 GIS was used to calculate what can be seen from these viewing points and corridors
(creating the Visibility map).
Visibility from major roads, based on topography and vegetation is an important consideration
in determining visual sensitivity (Figure 21).
The collective viewshed of all major roads and nominated scenic routes produces a
map depicting most of the landscape as being visible. Viewsheds from individual viewing
points are not shown here because there are too many overlapping points. Using the
map of viewing points and a GIS it is readily possible to calculate the viewsheds of
any of the viewing points or any other points that may be identified in the future.
(It is also helpful to use the GIS to calculate a viewshed in the opposite direction,
i.e., from the point that is being viewed.)
E.3 A topographic factor map was calculated that identifies visual sensitivity based
on slope and elevation.
The landforms in the County are a major contributor to what we see or don't see. Raised
elements like mountains and mesas are seen more often than low areas and depressions.
Slope and exposure are also important topographic considerations (See Figure 22).
The Topographic Sensitivity Map shows the vulnerability of raised and steep places
in the County.
E.4 Use the GIS to calculate a land cover factor map that identifies visual sensitivity
based on land cover types (creating the Land Cover influence map).
Land cover is one of the most important characteristics to be considered in examining
visual sensitivity in this County. This covering may be coniferous forest or industrial
park, open prairie or a parking lot. Different types of cover have various levels
of ability to absorb or mask change. Adding another building to an industrial park
may not change the nature of that landscape, while that same building in the midst
of a plowed agricultural field will stand out prominently. Figure 23 illustrates
some of these relationships.
Each landscape type was rated for its absorption capability and these characteristics
mapped to depict the county wide pattern.
E.5 Combine the Visibility map with the Topographic and Land Cover maps to map combined
visual sensitivity (creating the Composite Visual Sensitivity map).
The factors described above were those used to prepare the Composite Visual Sensitivity
Map. From publicly presenting a range of combination strategies for uniting these
three maps into one composite map, it was determined the land cover influences were
the most important. After land cover, topographic influence was of next most importance,
while visibility and near-to-far issues were the least important. A multiplier was
used when combining the three maps and as listed below:
Land Cover Sensitivity x 4 (plus)
Topographic Sensitivity x 2 (plus)
plus Visibility/Near to Far x 1
The weighting for this map was based on the premise that land cover was the strongest
controller of visual sensitivity.
The result of combining the three component maps together produces a map that depicts
county-wide visual sensitivity. The exposed southern mountains, mesas, canyons and
prairies appear to have the highest level of visual sensitivity. The areas with the
lowest visual sensitivity includes built up areas in and around towns, as well as the
heaviest vegetated areas associated with the Sangre de Cristo Mountains.
F. Findings
The conclusions of this study were drawn by examining both the Combined Scenic Quality
map and the Publicly Nominated Scenic Resources map. From that process, suggested
first priorities were identified. A map (Figure 4.) and a listing (Table 3.) of those
priorities is presented in the first part of this report. Further discussion is presented
below.
Industrial, commercial areas, which are scattered through the City of Santa Fe and
along highways, are generally of very low scenic quality. It may be possible, in
some cases, to mitigate this low quality with measures such as plantings between
the area and nearby key viewing points. In some areas, such as along Cerrillos Road, few such
opportunities now exist because of extensive strip development.
The mountains in the southern part of the County--the Ortiz, San Pedro, and South--are
of very high scenic quality and, as free standing mountains, are very prominent.
Mining in the Ortiz Mountains has created an area of very low scenic quality at
the edge of an area (the mountains) of extremely high quality. That high quality
area would be further degraded if the mine were to expand.
The very extensive area that extends south from the intersection of Highways 41
and 285 has a great deal of visual variety, with a mixture of open and wooded areas.
The very expansiveness of this area is likely a part of the reason for its high scenic
quality.
The pattern of low scenic quality associated with the agricultural lands in the
southwestern part of the County demonstrate a need to update the land cover information
for that area. Areas that are no longer in agriculture are showing up with the same
rating as the lands under pivot sprinkler irrigation.
The lower Galisteo Basin is a scenic area that is like an oasis of riparian vegetation
in the midst of a more arid area.
Caja del Rio Plateau is a large area on the western side of the County that has
strong public recognition as a place or a unit, perhaps because of its recreational
use. The ground rises gradually, for the most part, from the City of Santa Fe, but
has more dramatic topography on its riverside. This plateau shows up as a strong feature
in the scenic quality analysis because it was nominated by the public as a very large
area worthy of recognition. Taken as a whole it is a very significant landscape,
even though much of it is made up of terrain similar to many other places in the County and
it is not generally visible unless you are on top of it.
The Rio Grande Valley received one of the highest scenic quality ratings in the
County. This area is one of the icons of the County (along with the Sangre de Cristo
Mountains) and is a tremendous visual resource.
The Barrancas northwest of Pojoaque and the Cerrillos Hills are also areas that
were nominated by the public and show up here with high scenic quality.
The traditional irrigated valleys of Santa Cruz and Nambe/Pojoaque are of high scenic
quality on this map and received considerable mention through the public process.
The map suggests something that was borne out in discussions with the public: many
members of the public value the open expansiveness of some parts of the County. It
is not always the specific land cover of these areas as much as their quality of
openness. This suggests that there is a public value for extensive roadless areas.
Canyons, including part of Bandelier National Monument in the western part of the
County and the Santa Fe River Canyon through La Bajada are visually very rich.
The ski area in the Sangre de Cristos is another example (like mining in the Ortiz
Mountains) where something with low or neutral value is surrounded by great beauty.
Care should be taken if the ski area were to be expanded
Residential areas, whether in the city or in the County, were perceived as neutral
in scenic value. Residential areas in the County, such as Eldorado, are often surrounded
by scenic areas, so if the residential areas expand those scenic areas will be lose some of their scenic value.
Potential further GIS analysis
When an individual landscape type is selected and its potential rankings when paired
with all other landscape types are listed, planners can begin to see the potential
public reaction to siting certain land uses together.
For example, Table 6 shows (from most compatible to least compatible) are the types
of landscape and their ratings when adjacent to utility corridors. Such a list may
be useful when deciding future utility line alignments.
Note that only four types could be considered compatible (positive values), while
all types showing negative values would be considered incompatible. The highest visual
conflicts would occur if utility corridors were placed through or adjacent to aspens,
mountain foothills, unique land forms and features, canyon and mesa areas.
Lists like the one in Table 6 can be generated for each landscape character type.
Thus planners might use this kind of evaluation to help identify future locations
for rural residences or secondary roads, etc.
Recommendations for next steps in conserving scenic resources in Santa Fe County
1. Visual Resource Design Guidelines (design guidelines for development in "typical
landscapes")
Consider implementing a Visual Resources Management System that sets up guidelines
for development in the specific landscape character zones. These development and
design guidelines would specify acceptable design solutions to implement in each
typical landscape. For example, housing density, color, and configuration should vary greatly
between housing in the pinon-juniper woodland versus the prairie/ grassland areas.
The guidelines might include: setbacks, density and massing, grading and berming,
landscape materials and landscape protection, colors and architectural styles, etc.
2. Interface with the future Open Places Plan: Setting Priorities
In any open lands program, it is critical to have a clear and flexible methodology
for determining a course of action for any given time. Setting priorities through
a sound process will help to maximize each action that is taken toward conserving
important open lands. Knowing the value of the lands is an important first step. Visual resource
is one very important component that is looked at in an open lands program. Knowing
the landscapes that are valued by the community for its scenic quality allows those
lands to be added to the inventory of lands that are desirable to conserve and answers
the first question that must be asked, "Is the land worth protecting?".
3. Scenic Areas Overlay Zoning
Consider implementing an overlay zoning designation for the most highly scenic areas
within the county. This zoning designation would allow the county and other jurisdictions
to set additional guidelines for development, such as requesting detailed materials (including visual simulations) as part of the development application process.
4. Technical Assistance Team
A technical assistance team could be set up that would work with developers to ensure
that their projects are as visually compatible as possible. The team might consist
of specialists in architecture, landscape architecture, land planning, and visual
simulation. The developer would pay for this service as part of their planning process.
5. Ongoing Public Input into the Visual Resources Inventory
Consider an ongoing process to allow citizens to comment on important landscapes and
places in Santa Fe County. This would compensate for the relatively low public input
received in this study on the relative importance of the typical landscapes. A citizen's workbook could be developed to continue to educate the public about scenic resources
and to solicit additional input. This would allow the inventory to be refined as
the open lands plan gets put into place.
6. Revisions to Regulatory Tools: Incentive Techniques
As part of the process of developing guidelines for development in the various types
of landscapes, consider revising current regulatory tools to encourage developers
to create projects that protect more open land. Specific changes might provide incentives and bonuses to encourage cluster development, conservation easements, and transfer
of density rights (TDR).
7. Create a scenic areas registry that encourages residents to register their property
in a program that gives them a plaque for displaying roadside and generally raises
awareness of the significance of scenery.
8. Cooperate with land trusts to help in protecting sensitive areas. (Frequently they
can move faster in acquiring lands than a government agency and they then can sell
or donate the land to the County or some other appropriate agency.)
9. Provide the maps developed in this project to subareas (or neighborhoods) so that
the evaluations can be refined locally.
Process Discussion:
Why: To use public assessment of scenic quality there has to be a consistent rating
system so that an average rating can be reached.
Results: The participants at the meetings seemed to have little difficulty ranking
the 26 categories of typical landscapes. There was little or no comment on the names
used for the categories.
C.3 Have the public rate (from least to most compatible) the overall scenic quality
that would result when each typical landscape category occurs with each of the other
categories.
In the final exercise of the first round of meetings, participants evaluated the effects
of one landscape type on adjacent landscape types. Using a matrix that had all landscape
types on one axis and all potential adjacent types on the other, participants evaluated whether a potential relationship would be visually positive or negative.
Each respondent's evaluation was documented.
Why: Scenic quality can be reduced because of the proximity to something that is beautiful
something that is not. This exercise allowed the public to give their values for
these kind of relationships.
Results: Ratings of the compatibility of each potential pair of typical landscapes.
The matrix required considerable time to complete (20-30 minutes) and there were
some comments made about the unlikely occurrence together of several of the categories
of landscape. Response took the form of: positive (+), neutral, or negative (-). Participants
rated the relationship between all possible combinations of the 26 visual character
types and each response was recorded as follows: Positive visual relationship between types = +1, Neutral relation = 0, and negative visual relationship = -1.
D. Scenic quality analysis based on public values
D.1 Consolidate and digitize the publicly nominated scenic areas.
Why: To be used in the GIS the publicly nominated places had to be digitized. The
map provides locations for two typical landscape types: sacred places and unique
landforms and features.
Results: XXX map
D.2 Average the public ratings of the scenic quality of the typical landscape categories.
All of the participants' scores were averaged to compute a County-wide average.
Why: To be able to assign these average values to each category and ultimately to
map these values.
Results: County-wide averages for each category.
The resulting County averages are listed below, sorted from most scenic to least scenic.
They portray a high level of scenic quality for the mountain backdrop of the Sangre
de Cristo Mountains, unique land forms and features, Rio Grande Valley, the traditional irrigated valley, canyons, aspen forests, the desert mountains, scared places
and mesas. These landscapes are considered most scenic when individuals scenic preferences
were summed into a county average. Commercial areas, utility corridors, surface mines and industrial areas were considered the landscapes with the lowest scenic quality.
D.3 Use the GIS to map the typical landscape categories.
Using the data layers in the geographic information system (vegetation, topography,
land use and the public nominated special and unique places), the twenty six typical
landscape categories were mapped for the entire county.
Why: This is a very important map in the visual assessment process because it is an
intermediate between the landscapes types (reality)--photographs of which the public
can readily relate to--and abstractions of the landscapes--computer maps.
Results: Scenic Quality map
D.4 Recategorize the Scenic Quality map using the County-wide scenic quality averages.
Why: This step converts an inventory map (of landscape categories) into a map that
shows public values for scenic quality.
Results: XX map
D.5 Average the public ratings of relational scenic quality.
Why: An average of the public ratings allows these values to be mapped and therefore
integrated into the assessment process.
Results: The list of the resulting values is very lengthy. The following ranking shows
the most positive relationships that exist in the County, and when these landscapes
are seen adjacent to one another the scenic quality is improved because the relationship between each type.
Aspens:Sangre Uplands = 0.896
Canyons:Unique LANDFORMS & Features = 0.892
Desert Mt.:Unique LANDFORMS & Features = 0.857
Rio Grande Valley:Unique Landforms and Features = 0.821
Mt. Foothills: Unique Landforms and Features = 0.821
Desert Mt.: Mt. Foothills = 0.821
Arroyo/Creek: Unique LANDFORMS & Features = 0.793
Sangre Uplands : Unique LANDFORMS & Features = 0.785
Mt. Foothills: Prairie= 0.785
Mesas: Mt. Foothills = 0.785
Canyon: Mt. Foothills = 0.785
Arroyo/Creek: Mt. Foothills = 0.758
Arroyo/Creek: Aspens = 0.753
D. 6 Use the GIS to map the relational scenic quality of the study area, i.e., to
show the influence of adjacent scenery.
Why: This map was created so that the effects of adjacent scenery could be considered
in the map analysis.
Results: The XXX map
D.7 Combine the Scenic Quality and Relational Scenic Quality maps to map overall scenic
quality.
Why: This step produces the final scenic quality map by modifying the initial map
with the relational ratings, giving a map that represents two dimensions of scenic
quality.
Results: The influence map modifies the General Scenic Quality map by shifting its
values in a positive, neutral, or negative direction. When these two maps are combined
the influence map has the potential of affecting specific areas by as much as 20%
of the values assigned to the General Scenic Quality Map. For example, an area that had
a value of 3.44 on the General Scenic Quality map, may have specific areas enhanced
due to a very positive adjacent use to make that area's new value as much as 4.44;
or by a very negative visual relationship, lowered to 2.44.
The areas on the influence map do not correspond directly to landscape character type
units, since it is the edges of adjacent uses that are effected by this computation,
thus areas on the composite scenic quality map are not directly compatible either.
The resulting values from combining the general scenic quality map with the influence
map represent a ranking of scenic quality, from the highest to the lowest for the
entire county.
Highlights of Scenic Quality Map:
Mountainous areas are considered of highest scenic quality.
Unique land forms and features
Foothill areas
Canyons & River systems
Traditional Irrigation vs modern irrigation
Mesas, Aspens and Special Places
E. Visual sensitivity analysis based on expert judgment
Some parts of the Santa Fe landscape are more visually prominent than others. Specific
hillsides, fields and valleys are seen by large proportions of the population, while
other parts are only rarely seen. Those parts that are seen most often have the highest visual sensitivity, while those areas not seen are considered to have low visual
sensitivity. While all the characteristics of this perceptual phenomena are complex,

E.1 Consolidate and digitize the publicly nominated view points and view corridors.
Why: This step brings together all of the locations suggested by the public and puts
them into a digital form that can be used in the GIS.
Results: XX map
E.2 Use the GIS to calculate what can be seen from these view points and corridors
(creating the Visibility map).
Why: Visibility from major roads, based on topography and vegetation is an important
consideration in determining visual sensitivity.
Results: The collective viewshed of all major roads and scenic routes produces a map
depicting most of the landscape as being visible. The white areas on the following
map are areas not seen from the major network of roads.
E.3 Use the GIS to calculate a topographic factor map that identifies visual sensitivity
based on slope and elevation (creating the Topographic Influence map).
Why: The landforms in the county are a major contributor to what we see or don't see.
Raised elements like mountains and mesas are seen more often than low areas and depressions.
Slope and exposure are also important topographic considerations.
Results: The Topographic Sensitivity Map shows the vulnerability of raised and steep
places in the county.
E.4 Use the GIS to calculate a land cover factor map that identifies visual sensitivity
based on land cover types.
Why: Land cover is one of the most important characteristics to be considered in examining
visual sensitivity in this county. This covering may be coniferous forest or industrial
park, open prairie or a parking lot. Different types of cover have various levels of ability to absorb or mask change. Adding another building to an industrial
park may not change the nature of that landscape, while that same building in the
midst of a plowed agricultural field will stand out prominently. The diagram that
follows illustrates some of these relationships.

Results:Each landscape type was rated for its absorption capability and these characteristics
mapped to depict the county wide pattern. Land Cover Visual Sensitivity

E.5 Use the GIS to calculate a near-to-far factor map that identifies visual sensitivity
based on distance from view points and corridors (creating the Near-to-far Influence
map).
Why: A traditional means of characterizing visibility is to rate near ground, middle
ground and background. Those areas nearest to the viewer have a higher visual sensitivity
that areas in the distant background because they are more evident.
E.6 Combine the Visibility map with the Topographic, Land Cover, and Near-to-far influence
maps to map combined visual sensitivity (creating the Composite Visual Sensitivity
map).
The factors described above were those used to prepare the Composite Visual Sensitivity
Map. (WEAK) From publicly presenting a range of combination strategies for uniting
these three maps into one composite map, it was determined the land cover influences
were the most important. After land cover, topographic influence was of next most
important, while visibility and near to far issues were the least important. A multiplier
was used when combining the three maps and as listed below:
Land Cover Sensitivity x 4 (plus)
Topographic Sensitivity x 2 (plus)
plus Visibility/Near to Far x 1
Why:
Results: The result of combining the three component maps together produces a map
that depicts county-wide visual sensitivity. The exposed southern mountains, mesas,
canyons and prairies appear to have the highest level of visual sensitivity. The
areas with the lowest visual sensitivity includes built up areas in an around towns, as well
as the heaviest vegetated areas associated with the Sangre De Cristo Mountains.
F. Analysis
At the second round of public meetings, the results of first meetings were presented.
Participants were first given an overview of the planning process. Presented next
were a review of the specific input collected at the first public meeting and the
results that were quantified from that process. The maps that were generated using
the public values quantified from the earlier workshops were presented and explained in detail.
Finally, there was a discussion of how these maps could be used to inform future
county and neighborhood planning decisions.
Once the presentation of visual inventory and analysis mapping was complete, the participants
were asked to comment on all aspects of the project to date. Comments were recorded
and summarized after the meetings.

scenic lands are under private versus public ownership.

Next steps -further analysis
When an individual landscape type is selected and its potential rankings when paired
with all other landscape types are listed, planners can begin to see the potential
public reaction to siting certain land uses together.
For example, listed below (from most compatible to least compatible) are the types
of landscape and their ratings when adjacent to utility corridors. Such a list may
be useful when deciding future utility line alignments.
Note that only four types could be considered compatible (positive values), while
all types showing negative values would be considered incompatible. The highest visual
conflicts would occur if utility corridors were placed through or adjacent to aspens,
mountain foothills, unique land forms and features, canyon and mesa areas.

Lists like the one above can be generated for each landscape character type. Thus
planners might use this kind of evaluation to help identify future locations for
rural residences or secondary roads, etc.

Next Steps
Uses of the products of this study:
Problem areas, hazard areas and resource lands of all kinds are often included within
an open lands plan to conserve them or shelter them from inappropriate development.
However the significance of Visual resources within Santa Fe County suggests the
management of these visual resources alone may be warranted.

Citizens Workbook
(see draft mock-up included- this could be an appendix item in this report if there
is enough interest)
Recognizing that we haven't had as much public involvement as we would like, thus
keep the door open for additional input by defining the process as dynamic.
Open Lands Plan:
suggest a strategy to prioritize areas for possible inclusion within open lands plan
(recognizing that a site scale, parcel level assessment, will be required to realize
the ultimate implementation).
General Planning Contributions:
Project desirable locations for future uses to occur, knowing the implications of
those uses on visual resources (sf:clarify)
i.e. show sorted results of the relational affect of Rural Residences that depicts
the most to least appropriate landscapes for that use to occur.
Development Review Process:
Compare each development proposed to both the Visual Quality Map and the Visual Sensitivity
Map and ask the developer how they intend to address the issues both on and around
the project site. Thus used to negotiate mitigation measures.
Define Overlay zoning areas:
Demonstrate how these map products can be used to define a logical overlay zone that
could be amended to the county plan. Additional regulations and specialized review
processes would apply to all proposed development within this overlay zone.
Conclusions:
Since the project objective was to create a county-wide framework for visual resources,
the use of public domain data sets, coupled with site specific nominations of special
places accomplished those objectives very well.
Much of the problem was finding a methodology that was sophisticated enough for the
intellectual elite in Santa Fe, yet simple enough to explain in public meetings throughout
the County.
The technique of using survey result as weighting factors was very successful and
citizens that don't necessarily agree with the results, recognize that the results
are valid since it reflects their neighbors values rather than a expert's opinion.
The only way citizens will hold-the -line against future inappropriate growth patterns, is
if visual resources are a reflection of their values.
The County Open Space Plan approach to protecting the most significant scenic resources
appears to be a wise strategy.
