EXHIBIT E:   SCENIC AREAS, HISTORIC SITES AND STRUCTURES, 

AND ARCHAEOLOGICAL SITES 

Describe any existing scenic areas, historic sites and structures or archaeological sites 

in  the  vicinity of  the proposed  facilities and  state  the  effects,  if any,  the proposed 

facilities will have thereon. 

Exhibit  E  includes  summaries  of  existing  visual  (scenic),  historic  sites  and  structures,  and  cultural 

resources, as well as the potential impacts the proposed Project may have on each resource. 

E.1 Scenic Areas and Visual Resources 

E.1.1 Overview 

This portion of Exhibit E addresses the scenic and visual resources in the project area.  The study area does 

not contain designated national, state, or local scenic areas.  Visual resource inventory data were collected 

based on a review of existing and future  land use plans, aerial photography, field reconnaissance, and 

visual simulations to compare the visual impact of the proposed facilities with the existing facilities.  The 

narrative  that  follows provides  a description of  the  visual  resource  inventory  and  characterization of 

impacts to the landscape setting and the associated sensitive viewers. 

E.1.2 Landscape Setting 

The landscape setting for the Project study area is associated with urban or developed land within the City 

of  Tucson  and  Pima  County.  Generally,  within  the  study  area,  there  are  five  settings:  residential, 

commercial,  industrial,  park/recreation/open  space,  and  commuter,  each  of which  exhibits  a  unique 

landscape character. Each of these settings has viewers and associated viewer sensitivity, which pertains 

to the degree of concern for changes to the developed setting. Residential and recreational viewers are 

typically  associated  with  longer  viewing  duration;  therefore,  viewer  sensitivity  in  these  settings  is 

anticipated  to be high. Viewers associated with commercial and commuter settings are anticipated  to 

have moderate sensitivity, due to a shorter or temporary viewing duration. Sensitivity is anticipated to be 

low for industrial settings because these developments are associated with active industrial uses where 

viewers may not be as sensitive to changes in the landscape. The results of the visual inventory described 

by project alternative follow the methods. 

Alternative A 

This route travels arterial streets through Tucson.  The four‐lane roadways travel through areas that are 

characterized  by  industrial  buildings, warehouses,  commercial  establishments  including motels,  open 

space, mobile home parks,  and,  at  the north  end  of  the  route,  a  large mixed‐use  development  (the 

Bridges), residential neighborhoods, and a planned Open Space park.   Medians  in the roadways, when 

present,  contain  scattered  landscape  plantings.    Palm  trees  and  saguaros  that  occasionally  line  the 

roadways add to the existing vertical features along the route. 

The road beds are at‐grade, and therefore the distant views are limited to breaks in roadside plantings 

and buildings which line the streets.  Existing distribution and transmission lines, and lighting structures

E‐2  

line and cross the roadways.  Viewers that would have direct views of Alternative A along E Irvington Road, 

Benson Highway, and Park Avenue are associated mainly with  commercial  settings. Benson Highway, 

between  Tucson  Boulevard  and  Campbell  Avenue,  is  also  used  as  a  gateway  between  the  Tucson 

International Airport and the City center. 

Alternative B 

Approximately half of this alternative route parallels I‐10, a regional transportation corridor. I‐10 is a wide 

paved corridor that  is characterized with vertical structures such as: existing 138kV  lattice towers, tall 

highway  lighting  poles,  billboards  and  other  signage, which  are  similar  in  scale  to  existing  industrial 

facilities  (i.e., warehouses, manufacturing  facilities).   At  the east end of  the  route  there are scattered 

industrial and commercial buildings. The west section of I‐10 that the route parallels is bordered by the 

existing North Kino Sports Complex on the north side of I‐10 and the planned expansion of Kino Sports 

Complex on the south side of I‐10 and vacant land used as overflow parking for the sports and recreation 

facilities. 

This alternative route leaves the highway to head north along Campbell Avenue, aligning between existing 

and future commercial facilities facing Kino Parkway on the west, and existing residential neighborhoods 

on the east, paralleling existing power distribution lines and street lighting structures. 

Views along  I‐10 are  largely open and expansive due to superior (elevated) viewer position associated 

with the road bed. As such, distant views of the  larger developed area of Tucson, as well as the Santa 

Catalina Mountains to the north, the Rincon Mountains to the east, and the Tucson Mountains to the west 

are typical. Approximately 85,609 vehicles travel this route every day (per ADOT Average Annual Daily 

Traffic count  for  June).   Travelers using  this high‐volume corridor would have  relatively  short viewing 

durations;  therefore, viewer sensitivity  is anticipated  to be moderate. High sensitivity viewers  include 

recreation viewers associated with the Kino Sports Complex.  There are a large number of existing light 

poles which punctuate the vistas over the ball stops for the baseball fields at the complex. 

Views along Campbell Avenue include distant vistas of the Santa Catalina mountains to the north, big box 

retail stores to the west, and residential homes behind a screening of trees and shrubs.  Existing power 

distribution and light poles line the roadway.   

Alternative C 

Alternative C replaces  the section paralleling  I‐10 with segments along Palo Verde Road and Ajo Way.  

These four‐ and six‐lane roadways travel through areas dominated by industrial, warehouse, commercial, 

health care, and recreation facilities.  The remainder of the route is the same as for Alternative B along 

Campbell Avenue, as described above. 

The views along Palo Verde Road and Ajo Way are similar to those along E Irvington Road and Benson 

Highway.  At‐grade road beds limit distance views to breaks in buildings and landscaping.  Existing power 

lines and lighting poles line and cross the roadways.  Alternative C is different from Alternative A in that 

is also travels between the North Kino Sports Complex on the north side of Ajo Way and the South Kino 

Sports Complex and the Kino Veterans Memorial Stadium on the south side of Ajo Way. These complexes 

are circled by field lighting structures and there is also stadium seating at the Veterans Memorial Stadium.  

A  footbridge  spans Ajo Way  to  provide  for  pedestrian  traffic  crossing  between  the  north  and  south

complexes. The view of the project route by those enjoying the trails and paths in the North Complex is 

largely blocked by  vegetation, buildings,  and  landscape berms.    Power distribution poles  are  already 

visible along Ajo Way. 

E.1.3 Visual Simulations Methods 

Field work was conducted to photograph the existing conditions from various locations throughout the 

study area.   Eighteen (18) Key Observation Points (KOPs) were selected which best captured the view that 

could be impacted by construction of the new facilities.  The view of individuals traveling through the area 

on I‐10 and the arterial streets, residents in the neighborhoods, attendees of area schools, and users of 

recreational  fields  were  taken  into  account  in  selection  of  the  KOPs.  See  Exhibit  H  for  additional 

information regarding public facilities and Exhibit F for additional recreation opportunities in the project 

area. 

A georeferenced 3‐dimensional (3d) model was created, using the engineered transmission line design, 

structure locations, types, pole finish, and heights.  Note that only TEP’s standard pole finish, which is self‐

weathering steel was simulated and analyzed. The model included the proposed 138 kV transmission lines 

and towers, and the 138 kV substations.  Eighteen (18) visual simulations were created of the proposed 

condition to illustrate what the Project would look like to viewers in the study area.  See Exhibit G‐5 for 

simulations of the proposed facilities, and Exhibit J‐15 for the visual simulations in the format provided to 

the public.  

E.1.4 Visual Assessment Results 

The  visual  resources  impact  assessment  evaluated  the  level  of  visual  change,  or  contrast,  that  the 

proposed transmission  line would  introduce  into each  landscape setting  in conjunction with effects  to 

associated sensitive viewers. The components of the visual assessment included identification of the types 

of viewers and their sensitivity to the project in each segment of the route and characterization of impacts 

that were quantified as low, medium, or high. The visual impact assessment considered the effects of new 

structures (the proposed Project)  introduced  into the existing setting and associated sensitive viewers, 

which  considered  the  influence  of  existing  facilities  (i.e.,  existing  transmission  lines,  street  light 

structures).  

Overall, impacts are anticipated to be low for the proposed Project when it is adjacent to or parallel with 

similar  developed  settings  or  features,  such  as  industrial  settings,  because  visual  change  would  be 

reduced. Residential and park/recreation settings, which are typically characterized by open space and 

developed  recreational  facilities,  typically  result  in  greater  impacts  when  adjacent  to  the  proposed 

Project, because it differs in form and line. Commercial and urban settings are characterized by large to 

moderate sized structures and/or open space; here,  impacts are anticipated to be  lower because form 

and line are similar to the proposed Project. Visual impacts resulting from the Project would typically be 

reduced when: (1) the proposed route occurs within an industrial setting that is similar in form and line, 

and (2) the route is within a corridor that has existing 138 kV or 46 kV transmission lines. 

Potential visual impacts for each of the routes are described below.

E‐4  

Alternative A 

Alternative A (see Exhibits G‐5.1 to G‐5.7 and G‐5.9 for simulations) is compatible with the existing setting 

and impacts are anticipated to be low to moderate.  This conclusion is based on the mainly industrial and 

commercial setting along E Irvington Road and Benson Highway, and the mixed‐use setting of The Bridges 

at the north end of the study area. Moderate  impacts are anticipated to those residential and (future) 

recreational viewers in the area. Exhibit E‐1 provides more detailed information and identifies the types 

of viewers in each segment of Alternative A and the potential impacts to these viewers. The most sensitive 

segment  of  Alternative  A  is  along  the  portion  of  Benson  Highway,  between  Tucson  Boulevard  and 

Campbell  Avenue,  which  is  a  gateway  route  from  Tucson  International  Airport  to  the  City  center. 

Furthermore,  the north  side of  the  road  is  the  location of  the  future expanded Kino Sports Complex. 

Therefore, viewer sensitivity in this segment of Benson Highway is moderate to high. However, since there 

are existing 46 kV transmission lines with underbuilt distribution and existing light and traffic signal poles, 

the  additional  impact  to  commuters  (namely  tourists)  and  future  recreationists,  as  a  result  of  the 

proposed Project, would likely be only moderate and not rise to a high impact.  

The northern portion of Alternative A runs along Park Avenue and 36th Street. Here there are residences 

to the west and north and a mixed‐use (existing commercial and future residential) development to the 

east and south (The Bridges). Impacts would be moderate for these high sensitivity viewers because the 

existing setting includes electrical transmission and distribution lines and street lighting along 36th Street 

and Park Avenue and the setting is mixed‐use. 

Alternative B 

Alternative B  (see Exhibits G‐5.8  to G‐5.15  for simulations)  follows  Irvington Road  to  I‐10  to Campbell 

Avenue to 36th Street. The Irvington Road segment is as described above for Alternative A. The open views 

along I‐10, though they include vertical structures such as transmission lines, lighting, and signage, are not 

blocked from travelers as they are along the at‐grade roadways. Though these travelers are of moderate 

sensitivity, the length of open space and relatively unobstructed views along I‐10 increase the impact to 

commuters.    Impacts  to  the  residences  and  the  future Open  Space  Park  in  the north portion of  the 

Alternative B route along Campbell Avenue would be high because the only existing vertical features are 

wood distribution poles. While viewers along 36th Street are the same type as on Campbell Avenue, the 

existing setting includes electrical transmission and distribution lines and street lighting and are within a 

mixed‐use setting, which is more compatible with the Project, therefore impacts would be low. Exhibit E‐

1 provides more detailed information and identifies the types of viewers in each segment of Alternative 

B and the potential impacts to these viewers.  

Alternative C 

Alternative C (see Exhibits G‐5.9 and G‐5.13 to G‐5.18 for simulations) follows E Irvington Road to Palo 

Verde Road to Ajo Way, to Campbell Avenue, to 36th Street. The E Irvington Road segment is as described 

above for Alternative A and the Campbell Avenue and 36th Street segments are as described above for 

Alternative B. Impacts to viewers associated with commercial and urban settings along Palo Verde Road 

are anticipated to be moderate. The long distance views of the Santa Catalina Mountains along this stretch 

of Palo Verde Road would be broken up by the addition of taller vertical structures associated with the 

proposed Project. Impacts along the east end of Ajo Way are anticipated to be low as changes in existing

E‐5  

views are minor. Impacts to recreation viewers associated with Kino Sports Complex and the health care 

facilities at Kino Hospital, however, are anticipated to be greater, given the likely longer viewing durations 

of  recreationists,  although  the  existing  vertical  features  in  the  area  reduce  project  impacts.    New 

transmission line poles could also be visible to trail users as they are taller than the existing distribution 

structures. 

 

E.2 Historic Sites and Structures, and Archaeological Sites 

E.2.1 Overview 

A Class  I  records  review was  conducted by Tierra Right of Way  Services,  to determine  the extent of 

archaeological survey work performed along  the  three alternative routes, and whether any sites have 

been recorded within a 200‐foot‐wide buffer surrounding each alternative’s corridor, see Exhibit E‐2.   

5.2.2 Inventory Methods and Results 

The study included a records search of the Arizona State Museum’s (ASM’s) online database, AZSITE. The 

records review identified 110 cultural resource studies conducted within the Class I study area, which is 

within 0.5‐mile of each alternative route.  Of these studies, 12 have been conducted within the past 10 

years.   

The review identified 22 previously recorded sites, of which three (3) are within 100 feet of the alternative 

routes (see Exhibit E‐2, and Table 5).

Recommendations 

The archaeologist’s recommendations for the Project are to avoid the El Paso Natural Gas (EPNG) Pipeline, 

SR 80, and Country Club Road, and to abide by the requirements of A.R.S. § 41‐865 should any human 

remains or cultural materials be discovered during ground‐disturbing activities (Tierra, 2018b). These sites 

can  be  avoided  by  spanning  and  no  impacts  or mitigation  are  anticipated.  A  Class  III  survey will  be 

conducted upon approval of a route by the ACC and any impacts to newly discovered resources will be 

mitigated, as required by law.

April 10, 2018 Tucson Electric Power Company Attn: Renee Darling 3950 E. Irvington Road Tucson, Arizona 85714-2114 RE: Cultural Resources Records Search for the Irvington – Kino 138kV Line Siting Project At your request, Tierra performed a Class I records search of the Arizona State Museum’s (ASM’s) online database, AZSITE, to determine the extent of archaeological survey work performed along the three proposed route alternatives (Alternatives A, B, C) and whether any sites have been recorded within a 200-foot-wide buffer surrounding the project corridors. In addition, Tierra consulted the National Register of Historic Places to identify any National Register Historic Districts or buildings within a 200-foot-wide buffer surrounding the alternative project corridors. The study area, which encompasses all three of the transmission line alternative corridors, is in south-central Tucson and is roughly bounded by Irvington Road, Benson Highway, Park Avenue, 36th Street, Campbell Avenue, Ajo Way, and Palo Verde Road (Figure 1). Specifically, the study area is located within portions of Sections 28–33, Township 14 South, Range 14 East, Gila and Salt River Baseline and Meridian (G&SRB&M), as indicated on the Tucson, Arizona 7.5-minute 1: 24,000 U.S. Geological Survey (USGS) topographic quadrangle map. The Class I search began by identifying all previously recorded archaeological sites and projects conducted within one-half mile of the three proposed route alternatives (Figure 2). Archaeological sites are any area that contains physical remains of past human activity that are more than 50 years old and meet certain density and variety criteria. Previous projects include pedestrian field surveys conducted by qualified archaeologists to identify and evaluate archaeological sites. The search identified a total of 110 previous projects conducted within the Class I study area (Table 1). Of these, 12 have been completed within the past 10 years. Areas covered by surveys older than 10 years may require an updated, current resurvey. The Class I study area contains a total of 22 previously recorded sites located within one-half mile of the three route alternatives (Table 2). No National Register Historic Districts or buildings listed on the National Register of Historic Places are located within one-half mile of the proposed alternatives. The results of the search by each proposed alternative route (Alternatives A, B, and C) and information on previous surveys and previously recorded archaeological sites within the 200-foot buffer are presented below. The 200-foot buffer centered on each alternative route was used to identify projects that intersect the proposed alternative corridors and to identify archaeological that may be impacted by the proposed undertaking. Alternative routes within 100 feet of all previous projects and previously recorded sites within 100 feet of the alternatives are identified in Tables 1 and 2. Of the 22 archaeological sites located within the Class I study area, only three sites are located

Page 12: EXHIBIT E: SCENIC AREAS, HISTORIC SITES AND STRUCTURES ...

2

within 100 feet of or are crossed by the proposed route alternatives and could be impacted by the proposed undertaking. Only these three sites are analyzed below by alternative.

Alternative A

Alternative A is 4.64 miles in length. The S. Park Avenue portion of Alternative A was surveyed in 2012 (2012.73.ASM) approximately 0.77 miles have been surveyed in the past 10 years (2008-355.ASM and 2012.73.ASM). Approximately 3.85 miles of Alternative A have not been surveyed within the past 10 years, and the relevant land managing agencies may require a new survey. Because Alternative A follows existing developed road rights-of-way, especially E. Benson Highway and E. Irvington Road, there is very little potential for the survey to identify significant archaeological sites within the project corridor. Two archaeological sites are crossed by Alternative A: AZ AA:12:875(ASM), El Paso Gas Pipeline No. 1007, and AZ FF:9:17(ASM), State Route 80 (see Figure 2). Both are in-use linear features that include portions determined eligible by SHPO. Power poles would be placed to avoid the gas line and placed within the State Route 80 right-of-way; therefore, no impacts are anticipated and the undertaking would result in no adverse effect.

Alternative B

Alternative B is 3.63 miles in length. Only a narrow portion of Alternative B is crossed by a project completed within the past 10 years (2008-355.ASM), and the relevant land managing agencies may require a new survey of the entire corridor. Because Alternative B follows existing developed road rights-of-way, especially the I-10 corridor and E. Irvington Road, there is very little potential for the survey to identify significant archaeological sites within the project corridor. One linear archaeological site, AZ BB:13:688(ASM), Country Club Road, is crossed by Alternative B. This is an in-use linear feature that includes portions determined eligible by SHPO. Power poles would be placed within the road right-of-way; therefore, no impacts are anticipated and the undertaking would result in no adverse effect.

Alternative C

Alternative C is 4.26 miles in length and has been partially covered by portions of three projects within the past 10 years (2008-816.ASM, 2008-355.ASM, 2013-486.ASM). Approximately 3.8 miles of Alternative C have not been surveyed within the past 10 years, and the relevant land managing agencies may require a new survey. Because Alternative C follows existing developed road rights-of-way, especially E. Ajo Way, S. Palo Verde Road, and E. Irvington Road, there is very little potential for the survey to identify significant archaeological sites within the project corridor. One linear archaeological site, AZ AA:12:875(ASM), El Paso Gas Pipeline No. 1007 crosses the alternative. It is currently in use and includes portions determined eligible for the NRHP by SHPO. The linear feature is in use and power poles would be placed to avoid the gas line; therefore, no impacts are anticipated and the undertaking would result in no adverse effect.

Alternatives Analysis

TEP identified 11 criteria to be used in their alternatives analysis that are aligned to the CEC decision factors (Arizona Revised Statute § 40-360.06) and TEP’s design philosophy and standards. Tierra was tasked with assessing Criterion 7, which is described as: Criterion 7 - Known or potentially eligible cultural resources in the corridor as measured by documentation through previous survey effort and ranked by degree of mitigation required. Using Criterion 7, each alternative was scored based on the results of the cultural resources literature and records review, in which locations of recorded cultural resources were overlaid on maps of the study area and the alternatives. A score of 3 was given to alternatives where no impacts to known or potentially eligible cultural resources would occur. A score of 2 was given to alternatives where known or potentially eligible cultural resources would be impacted but could be mitigated. A score of 1 was given to those alternatives where impacts to known or potentially eligible cultural resources would occur and could be mitigated, but mitigation would approach cost- prohibitive. All three alternatives cross linear sites that are currently in use and where only portions have been determined eligible for the NRHP by SHPO. None of the alternatives would result in impacts to known or potentially eligible resources; therefore, all alternatives scored a 3.

Recommendations

Because only small portions of each alternative have been surveyed within the past 10 years and portions of each alternative have not been surveyed, Tierra recommends Class III surveys for significant portions of the selected alternative. A cultural resources survey would be required to identify, record, and assess the significance of any prehistoric or historic cultural resources within the project area that might be adversely affected by the proposed undertaking. However, because each alternative follows existing developed road rights-of-way and no significant prehistoric or historic archaeological sites have been identified in this part of Tucson, there is little potential for the survey to identify significant archaeological sites within any of the project corridors. If you have any questions, please feel free to contact me at (520) 319-2106. Sincerely,

Jerry D. Lyon Principal Investigator, Environmental Planning and Cultural Resources Division
