BACKGROUND

The following is a brief summary of pertinent background information on the project. It is included to

provide the basis and reference for the Historic Effects Assessment, but not intended to be

comprehensive standalone information on the project itself. For that information, please refer to the

original documents cited and/or the sources provided.

Property Description

The United States Naval Base, Pearl Harbor (Pearl Harbor) was designated as a National Historic

Landmark (NHL) for its historic function as an active naval base with a mission to support the U.S. fleet.

That function was performed to the date of the nomination and continues into the 21st Century. Because

of the effectiveness of Pearl Harbors’ mission, the naval base was attacked by aircraft of the

Japanese navy on December 7, 1942. During that attack, the USS Arizona sunk with more than a thousand Americans on board, who are now entombed in the wreck. The wreck can be accessed as

part of the USS Arizona Memorial, which is at the center of the Pearl Harbor NHL. The attack by the

Japanese Navy caused the United States to enter World War II, contributing to the historical

significance of the property.

Property Boundary

On the basis that the fundamental quality that defines Pearl Harbor as a national historic landmark is

based on its historic function, which continues to date, as well as the attack on December 7, 1941;

then the boundary of the landmark includes those water and land areas that have historically been

intimately and directly associated with that function and action. The NHL boundaries contain various

built resources ranging from buildings directly related to the Navy’s wartime work to more modest

support buildings. All of the water areas of Pearl Harbor are included within the project boundary in

addition to certain adjacent land. A detailed verbal description of the boundary of the NHL is included

in the nomination form to the National Register of Historical Places (NRHP). The boundaries of the

landmark include those water and land areas historically, intimately, and directly associated with the

property’s use as a historic naval base, with mission to support the U.S. Fleet, and the attack on

December 7, 1941. See National Register of Historic Places Inventory Nomination Form for verbal

description of boundary. (Attachment 1)

Project Description

Within proximity to the NHL, the Honolulu Rail Transit Project (Project) will be located within

Kamehameha Highway. The design of Pearl Harbor Naval Base (PHNB) Station itself is driven by the

characteristics of the existing site and efforts to provide safe and direct access to the station by all

modes, particularly pedestrians. The only access to the station will be from properties on the mauka

side of Kamehameha Highway and is facilitated via a generous station plaza that connects to adjacent

sidewalks, facilitating safe pedestrian access from adjacent residential neighborhoods surrounding the

station and from the Naval Base across Kamehameha Highway. All access to the station plaza and the

station itself is fully ADA compliant and focused on enhancing the pedestrian experience.

Project Design

Most of the building elements associated with the station are configured like a pavilion. This open

setting, allowing for natural sunlight and ventilation to flow freely through the station, corresponds to

and is respective of its park-like setting. It is also inspired by and respectful to the adjacent Makalapa

Navy Housing Historic district and it’s planning principals, which followed “Garden City” concepts that

were prevalent at the time of its development. Most of these features of the station design were

developed in coordination with and in response to comments and feedback received from the

Consulting Parties and other affected stakeholders in response to earlier conceptual station designs.

Particular design modifications that were implemented include:

- A lighter and less massive entry structure compared to the one presented in the original preliminary

engineering design

- A canopy design that recalls the angular forms of the Makalapa housing and simultaneously creates

a treelike, layered configuration of the canopies recalling the adjacent existing Monkeypod trees

and the park-like setting of the existing conditions

- A smaller footprint of the station pavilion, shifting the station itself mauka from the original location

and allowing additional landscape features to be protected.

Most importantly the design delivers on one of the key requests established during previous reviews by

the Consulting Parties and other stakeholders of the project. Specifically, it implements a design that

restricts all touch downs for pedestrian access to the mauka side of Kamehameha highway and does

not take any of the Pearl Harbor NHL property.

Most importantly, the makai edge of the guideway will generally be approximately 25 feet from the

mauka edge of the NHL boundary, aiding to assure that the project will be a substantial distance away

from the NHL and will not eliminate primary views of or from the elements that contribute to its eligibility

and are identified as having potential for adverse effects under Section 106. The design and

configuration of the station and guideway in this area will be in accordance to the section illustrated in

Figure A-1 below.

Governing Regulations

The U.S. Naval Base Pearl Harbor NHL was listed in the National Register of Historic Places (NRHP) in

1974 with exact boundaries accepted in 1978. The designation of Pearl Harbor as a NHL makes it

subject to the requirements of the Secretary of the Interiors Standards (36 CFR 68.1) for the treatment

of historic properties.

The project’s Environmental Impact Statement (EIS) and particularly the Section 4(f) Evaluation in

Chapter 5 of the EIS identify the Pearl Harbor NHL as a whole, the Ossipoff’s Aloha Chapel, SMART

Clinic, and Navy-Marine Corps Relief Society – Facility 1514, as well as the Makalapa Navy Housing

Historic District specifically as having potentially adverse effects triggered by the implementation of the

PHNB station. (Figure A-2) The purpose of this report is to evaluate effects on the Pearl Harbor NHL only

since it is the only historic property affected by the optimized design.

The Honolulu High Capacity Transit Corridor Project (HHCTCP) Programmatic Agreement establishes a

series of stipulations that shall be implemented in order to take into account the potential adverse

affects of the project on existing historic properties

Figure A-2 – Historic Properties in Areas of Potential Effects

The purpose of this Historic Effects Assessment (HEA) report is not to replicate, revise, or replace the

assessments made previously under these governing regulations. The purpose is to establish that the

design optimization efforts required at the PHNB Station do not represent additional or more severe

adverse impacts than those that have previously been found acceptable under the governing

regulations listed above. This report will establish that the revised, optimized design fits well within the

agreements reached between participating parties under the governing regulations applicable.

Previous Assessments

Previous assessments regarding the potential adverse effects of the construction of the PHNB Station

on the Pearl Harbor NHL have been completed as part of the preparation of the EIS for the project. The

previous assessment has been organized along the commonly recognized seven aspects or qualities

that establish the integrity of a NHL. Below is a summary of that assessment. The full assessments are

included in Attachment 2 of this report.

Location: No Effect. The Pearl Harbor NHL and its contribution resources retain integrity of location and

this would not be altered by the project. The NHL resources and their relocated boundaries would

remain in their current location and are not utilized by the project.

Design: No Effect. The Pearl Harbor NHL’s contributing resources retain a reasonably high level of

integrity of design. As outline in the nomination form Pearl Harbor is by nature subject to changes in the

base’s mission and configuration. While change to the design of the historic resource is therefore

inevitable and anticipated, the project does not contribute to these changes.

Setting: No Adverse Effect. The project would be visible from select areas of the NHL but would not be

visible from other portions. Numerous other changes to the setting of the NHL have not affected the

integrity of its setting. These changes include modifications to the increasingly busy Kamehameha

Highway which has been widened in some areas and has seen the addition of tall power transmission

poles that dwarf surrounding structures. The project itself would not be visible from the vast majority of

the NHL property particularly since the NHL, based on its character as a naval base is oriented to its

harbor and not the mauka side. While the station and guideway of the project introduce new elements

to the setting of the NHL creating an effect, these changes do not result in an adverse effect.

Materials: No Effect. The project would not alter the current integrity of materials. All project work would

occur outside of the NHL’s boundary and the project would not affect the integrity of materials.

Workmanship: No Effect. The project would not affect any characteristics or features related to the

workmanship used to create the property’s historic elements. No project activity would occur within NHL

boundary.

Feeling: No Effect. The Pearl Harbor NHL has a high level of integrity of feeling and conveys its origin as

a significant pacific naval base. This feeling is created by the presence of its many World War II-era

buildings and structures that remain on site today. The site’s military mission remains clear, due in large

part to its orientation to the harbor as a naval resource. The addition of the PHNB Station would have

no effects on the NHL property or diminish the expression of its historic character.

Association: No Effect. Pearl Harbor NHL has a high level of integrity of association and continues to

demonstrate its role in the establishment of the U.S. Navy in the Pacific during World War II. The project

would not alter this integrity which is directly related to its designated resources and not the surrounding

environment outside of the NHL boundary.

Summary Finding: The project would have No Adverse Effect on the Pearl Harbor NHL. Construction of

the guideway would not adversely affect the historic landmark’s integrity, although the project would

introduce new elements into areas outside of the property’s NHL Boundary.

Pending National Historic Landmark Applications

STG understands that, under the agreements reached within the Programmatic Agreement, the City of

Honolulu will be processing a nomination of the Little Makalapa Navy Housing Historic District to the

NRHP. By the time of completion of this report the status of that nomination had not yet been finally

determined. As a result, the evaluation of any potential adverse effects to this possible future NHL is

not a part of this report. Additionally, since the focus of this report is a comparative analysis of any

additional, or more sever adverse effects, the analysis of any potential impacts to potential additional

historic properties will have to be a part of a separate analysis.

Objective

The objective of this report in return is to document that the design, in all of the categories evaluated,

has equal or less adverse effects to the integrity of the Pearl Harbor NHL than the design previously

agreed to. The next chapter of this report will describe the path that led to the current design, document

its critical components, and complete an item by item comparison of the adverse effects to reach a

summary finding.

A significant amount of work has been completed on establishing the findings of “No Adverse Effects”

on the Pearl Harbor NHL by the project. In addition to all required environmental documentation for the

project that has been completed in accordance with federal requirements, the completion of the

Programmatic Agreement stands out as the record of a broad agreement that has been reached

between all partied involved to establish what constitutes an acceptable project. This Programmatic

Agreement is for regarding the Honolulu High-Capacity Transit Corridor Project in the City and County of

Honolulu, Hawaii and is made between:

- The U.S. Department of Transportation Federal Transit Administration

- The Hawaii State Historic Preservation Officer

- The United States Navy

- The Advisory Council on Historic Preservation

This Programmatic Agreement establishes a series of stipulations that, as long as fulfilled, will result in

the project being acceptable to all those that are a party to the agreement.

The objective of the design optimization efforts for the PHNB Station has been to fully respect the

commitments made in the Programmatic Agreement and deliver a design that continues to meet all

stipulations outlined therein and, as a result does not require any revisit of the agreement itself or any

of the commitments made in it.

EVALUATION OF POTENTIAL ADVERSE AFFECTS

Design Status

At the time of the completion of the project’s RFP drawings the configuration of the foundation systems

on the makai side of Kamehameha Highway remained unresolved. While the RFP documents illustrated

structural support columns on the makai side, notes on the structural drawings included in the RFP

indicated that a cantilevered solution might have to be evaluated. (Figure A-3)

Figure A-3 – North Elevation of PHNB Station at NHL in RFP

The Project Specific Requirements (PSR) and specifically Section 1.7.3.B.2.b and Section 1.7.3.B.2.c

identify potential conflicts with existing underground utilities, namely Navy communication facilities. It

is of note that the PSR do not make any reference to the potential impact of the resolution of these

conflicts to the integrity of the NHL other than the previously established requirement that no facility

shall be located within the Pearl Harbor National Historic Landmark. In order to address the potential

conflicts with the Navy communication facilities the PSR requires the following actions:

- Performance of a field investigation to determine locations of existing utilities

- Coordinate with the Navy

- Evaluate a cantilevered concourse with no foundation structure on the makai side of Kamehameha

Highway.

- Modify the conceptual design shown on the RFP drawings to construct the station structural

components such that there shall be “no outage” of the communication facilities

The following sub sections of this report illustrate the efforts that were undertaken in response

to these required action items.

10



Subsurface Investigation

STG conducted an extensive investigation to identify and record all existing subsurface improvements

in the vicinity of the Navy communication facilities. These investigations utilized both, research into

existing utility as-builds and record drawings that were made available, as well as extensive potholing

in the field to identify subsurface improvements that were not, or only insufficiently documented.

The findings and results of that subsurface investigation were modeled in a comprehensive 3D model

to assure that the extent of all subsurface improvements and all clearances associated with them were

available in a geospatially correct depiction. Figure A-4 shows a screen shot of the utility map. While

that figure is a single static representation of the design data included in the model it is important to

note that all utilities were modeled in a 3D model and the data contained in that model was used in the

evaluation of all optimized design solutions discussed in this report.

Figure A-4 – Subsurface Investigation Data

The results of the subsurface investigation discovered a significant amount of utilities in a complex

geometric configuration. It also discovered utilities that were installed within the last few month prior to

the writing of this report that had not been documented within any of the as-builts or record drawings

that were available. The investigation confirmed significant congestion of existing utilities within the

public ROW, but it also identified an area within the footprint of an existing bus stop that is outside of the

NHL boundary but is virtually free of existing utilities. The report will discuss the exploration of the bus

stop area in more detail in later sections.

11



Cantilevered Concourse Solutions

While the area of the existing bus stop was identified as a potential location for structural support of

the pedestrian bridge, consistent with the suggestion in the PSR STG initiated an evaluation of potential

cantilevered solutions for the pedestrian bridge. During the coordination of potential cantilevered

solution HART suggested that design team members evaluate the conceptual solution developed for

the project’s Chinatown Station and re-emphasized that notes in the RFP drawings suggested a

cantilevered solution be evaluated to avoid impacts to the Navy communication facilities. STG

intentionally cast a wide net to explore a series of cantilevered solutions. These concepts were initially

developed without constraints with respect to the adjacent NHL, or any project commitments that were

made in earlier stages of the project.

The intent of that approach was to assure that no potential solution was precluded from the evaluation

and the resulting assessment would represent an exhaustive evaluation of all potential cantilevered

solutions and determine their suitability to deliver a “no outage” solution without violating any of the

requirements of the governing regulations and the commitments made in the Programmatic Agreement.

Figures A-5 through A-9 illustrate the range of potential cantilever solutions evaluated. Attachment 3 to

this report provides more detailed information and plan views of the alternates considered.

Figure A-5 – Cantilevered design solution with extended hammerhead

Figure A-5 illustrates a solution that extends the existing hammerheads of the main guideway girders

allows for a reduction in the free cantilevered length of the makai side of the pedestrian bridge to control

deflection and torsional movements of the elevators located at the end of the pedestrian bridge. The

solution additionally considered the relocation of the elevators and position them closer to the platform

girders for the same reasons.

12



Figure A-6 – Cantilevered design solution with modified hammerhead

Similarly, Figure A-6 depicts a solution that modifies the existing hammerheads to increase their

structural capacity to account for the cantilevered elements located furthest away from the platform

girders. In addition the design introduces a steel truss that is paired up with the hammerhead to create

a balanced structural support system for the pedestrian bridge and vertical circulation elements on either

side of it.

Figure A-7 – Cantilevered design solution with supporting truss

Figure A-7 depicts a design solution that is similar to a solution currently contemplated for the Chinatown

station, which is part of the City Center Guideway and Stations of this project. The design envisions a

large truss extending from the pedestrian bridge level below the platform to above the canopies of the

platform, forming a large structural support system that carries the cantilevered elevators on the makai

side of Kamehameha Highway.

13



Figure A-8 – Cantilevered design solution with off-center mast support

Acknowledging the cantilevered character of the desired design solution, Figure A-8 depicts a scenario

that introduces a new major structural element in the form of a large mast support that utilizes cable

stay supports to facilitate the cantilevered pedestrian bridge and supports the elevators at the end of

that cantilever. To achieve proper support angles, the mast is likely to become the tallest element of that

design.

Figure A-9 – Cantilevered design solution with center mast support

Similar to the off-center mast solution, the center mast solution depicted in Figure A-9 introduces a new

structural element to the station design. This center mast is placed in line with the existing guideway

piers and supports a cantilevered pedestrian bridge and associated circulation element on either side.

This mast would also become the tallest element of the station design.

14



Summary of Cantilevered Concourse Solutions Evaluation

A number of the evaluated cantilevered concourse concepts show potential to provide support of the

PHNB Station pedestrian bridge without affecting the Navy communications facilities and without

placing any improvements within the boundary of the NHL.

However, all concepts include significant alterations to major project components, or require the

addition of new project elements. Both of those changes have the potential to significantly alter the

appearance of the station. As illustrated above the Setting and the Feeling of the Pearl Harbor NHL are

two of the critical aspects or qualities that establish the integrity of it as a NHL. Significantly altering the

design of the station and/or adding significant new elements therefore carries significant potential for

additional or more severe impacts to the integrity of the Pearl Harbor NHL.

Particularly the concepts depicted in Figure A-7 through A-9 that require a significant increase in the

overall height of the PHNB station have the potential to become more visible from within the NHL, which

could create additional adverse effects. The setting of the NHL and the dominance of its orientation on

its harbor is a critical factor in its integrity. The assessment of “no adverse effect” on this Setting quality

is largely based on the fact that the PHNB station would not be visible from within the NHL. An increase

in height of the station design and the resulting ability to see the station is likely to adversely affect the

assessment of that quality.

Additionally, the Programmatic Agreement conveyed a specific station character and resulting aesthetic

image to a large group of Consulting Parties. This station character represents the project team’s

commitment to the Consulting Parties and the general public for delivery. Any design solution that

triggered significant deviations from those aesthetic solutions are seen as carrying the risk to re-open

the evaluation by the Consulting Parties. In coordination with HART, STG determined that the potentially

larger adverse effects on the Setting and Feeling qualities of the Pearl Harbor NHL as well as the

potential project delay from additional project reviews did not make support the selection of either of

the cantilevered design solution as the preferred option.

As a result, neither one of the cantilevered design concepts were seen as resolving the multifaceted

requirements at this location and STG began the evaluation of other “no-outage” solutions as required

by the stipulations in the PSR. Particularly the area of the existing bus stop was more closely evaluated

since it is the only area on the makai side of Kamehameha Highway and outside of the Pearl Harbor

NHL boundary that is virtually free from existing utilities and allows for the placement of support

columns as originally envisioned by the RFP designs without affecting the Navy communications

facilities.

15



Supported Concourse Solutions (no-outage solution)

The existing bus stop on the makai side of Kamehameha Highway is a standard bus stop with a small,

standard bus shelter positioned along the boundary of the NHL. Figure A-10 shows the existing

conditions of the bus stop. The photo was taken just prior to the potholing activities that STG undertook

to confirm the lack of any conflicting underground utilities.

Figure A-10 – Photo of existing bus stop on makai side of Kamehameha Highway

In order to take advantage of this area of public ROW outside of the NHL that is completely free of existing

utilities STG developed a design that reorganizes the location of the vertical circulation elements of the

station to be located above the area of the current bus stop. This reconfiguration allows for the

implementation of a pair of slender columns on either side of the existing slab on grade of the bus stop

to support the elevators, staircase, and pedestrian bridge above.

To minimize the loads required to be supported in this location, and in return minimize the sizes of

structural members touching down STG has additionally added supports for the pedestrian bridge to the

hammerheads of the project guideway. All of these design optimization strategies result in:

- A “no outage” solution

- A design that is similar to, yet optimizes the design concept included in the RFP

- A more efficient steel structure

- A “cleaner” more intuitive circulation pattern for passengers accessing the station

- A balanced structural design for the pedestrian bridge that employs similar solutions on both mauka

and makai ends.

elements and the constraining utility information below.

17



Adverse Effects

As indicated in prior sections of this report, the evaluation of adverse effects of the optimized design

solution for PHNB Station on the Pearl Harbor NHL is less of a standalone evaluation on neutral terms,

but much rather a comparative analysis of how the newly developed solution performs against the

established 7 aspects and qualities that establish the integrity of the NHL. Figure A-13 shows the

appearance of the proposed optimized station design and illustrates how it utilizes only formal elements

that have already been established by the previously prepared design solution that resulted in the “No

Adverse Affect” designation under the governing regulations of the project. Particularly with respect to

Materials and Workmanship the optimized design is well within the parameters established by the RFP

design and does not create any additional adverse effects.

Figure A-13 – View north along Kamehameha Highway

While the image above provides proof that the station elements utilizes design elements that are all

within the established vocabulary of the previously approved station design, the view itself, or the

appearance of the station as viewed from Kamehameha Highway was not a part of the “No Adverse

Affects” assessment under the Secretary of the Interiors Standards, nor was this view shared with the

consulting parties during the agreements reached under the programmatic agreement.

18



The figures below illustrate a comparative analysis of the renderings previously communicated to the

consulting parties with current views of the optimized design.

Figure A-14 – View of RFP design looking south Figure A-15 – View of optimized design

The view looking south included in the Programmatic Agreement is focused on the entry pavilion to the

station and its revised design that acknowledges the “park-like” setting of the existing condition and the

adjacent Makalapa Navy Housing District. The optimized design has no affect on this view and allows for

the design to be implemented as originally envisioned.

Figure A-16 – View of RFP design looking west Figure A-17 – View of optimized design

The view looking west illustrates that the optimized design allows for the implementation of a design

solution that is identical to the design previously evaluated. The lack of any new structural elements and

the continuation of the “tree-like” roofs as the station’s tallest project elements allow for the visual

character of the station to remain unchanged.

19



Summary Findings

The following is an item by item review of the aspects and qualities that contribute to the integrity of the

Pearl Harbor NHL with a particular evaluation as to whether or not the design optimizations trigger any

change in the designation of its effect. Since this is a comparative analysis, the original assessment is

repeated with the particular discussion of the quality based on new or optimized design features

included in bold below it.

Location: No Effect. The Pearl Harbor NHL and its contribution resources retain integrity of location and

this would not be altered by the project. The NHL resources and their relocated boundaries would

remain in their current location and are not utilized by the project.

The station location is not affected by the optimized design. All major project elements remain in their

current location and all pedestrian access points are unaffected. The assessment continues to be: No

Effect.

Design: No Effect. The Pearl Harbor NHL’s contributing resources retain a reasonably high level of

integrity of design. As outline in the nomination form Pearl Harbor is by nature subject to changes in the

base’s mission and configuration. While change to the design of the historic resource is therefore

inevitable and anticipated, the project does not contribute to these changes.

The minor changes to the station design does not trigger or contribute to any changes in the design of

elements of the NHL. The assessment continues to be: No Effects

Setting: No Adverse Effect. The project would be visible from select areas of the NHL but would not be

visible from other portions. Numerous other changes to the setting of the NHL have not affected the

integrity of its setting. These changes include modifications to the increasingly busy Kamehameha

Highway which has been widened in some areas and has seen the addition of tall power transmission

poles that dwarf surrounding structures. The project itself would not be visible from the vast majority of

the NHL property particularly since the NHL, based on its character as a naval base is oriented to its

harbor and not the mauka side. While the station and guideway of the project introduce new elements

to the setting of the NHL creating an effect, these changes do not result in an adverse effect.

The optimized station design does not increase the height of the station, nor does it extend or increase

the footprint of the station. As a result the visibility of the station from the NHL itself is not affected. The

assessment continues to be: No Adverse Effects

Materials: No Effect. The project would not alter the current integrity of materials. All project work would

occur outside of the NHL’s boundary and the project would not affect the integrity of materials.

The optimized station design does not alter the current integrity of materials since it does not introduce

any new materials. The assessment continues to be: No Effects

Workmanship: No Effect. The project would not affect any characteristics or features related to the

workmanship used to create the property’s historic elements. No project activity would occur within NHL

boundary.

No changes have been implemented in the optimized design that would affect the workmanship of the

property’s historic elements. The assessment continues to be: No Effects

20



Feeling: No Effect. The Pearl Harbor NHL has a high level of integrity of feeling and conveys its origin as

a significant pacific naval base. This feeling is created by the presence of its many World War II-era

buildings and structures that remain on site today. The site’s military mission remains clear, due in large

part to its orientation to the harbor as a naval resource. The addition of the PHNB Station would have

no effects on the NHL property of diminish the expression of its historic character.

The orientation of the Naval Base continues to be onto its harbor. None of the changes implemented in

the optimized design solution affects this aspect. The assessment continues to be: No Effects

Association: No Effect. Pearl Harbor NHL has a high level of integrity of association and continues to

demonstrate its role in the establishment of the U.S. Navy in the Pacific during World War II. The project

would not alter this integrity which is directly related to its designated resources and not the surrounding

environment outside of the NHL boundary.

None of the station elements of the optimized station design are placed inside the Pearl Harbor NHL

boundary. No changes to its integrity are made. The assessment continues to be: No Effects.

Summary Finding: The project would have No Adverse Effect on the Pearl Harbor NHL. Construction of

the guideway would not adversely affect the historic landmark’s integrity, although the project would

introduce new elements into areas outside of the property’s NHL Boundary.

The key findings of the previous “No Adverse Effect” findings remain unchanged. The optimized station

design does not adversely affect the historic landmark’s integrity. The project introduces some new

elements outside of the NHL boundary but the optimized design does not affect those elements in a

significant way. The optimized station design does not alter this summary finding.

21



SUMMARY AND RECOMENDATIONS

Summary

The RFP design documents for the Pearl Harbor Naval Base station included a design for the makai

support of the pedestrian bridge that was unresolved. To address that condition and to develop a

corresponding design solution the PSR for the project include a number of specific requirements to be

met in order for the design to comply with the previously granted approvals.

In response to those PSR requirements STG has coordinated with HART and developed an optimized

station design solution for the Pearl Harbor Naval Base station that meets all of the requirements

stipulated in the PSR.

- It does not affect the Navy communication facilities

- It does provide a “no outage” solution

- It does not place any project element inside the Pearl Harbor NHL boundary

Based on the analysis presented above which was performed in compliance with the standards of

Secretary of the Interiors this optimized design solution does not create any additional or more adverse

effects to the integrity of the Pearl Harbor NHL. All elements of the optimized station design are based

on the formal language previously established and the developed design solution has minimal impact

to the aesthetic character of the station.

Recommendations

As a result and as documented in this Historic Effects Assessment the optimized design solution for the

Pearl Harbor Naval Base station meets the requirements of the governing regulations of the project and

is recommended to be further developed as the final design solution for the project. The solution

continues to be governed by previously reached agreements and environmental clearances and is

compliant with the Secretary of the Interior’s Standards.
