Executive Summary This Preservation and Maintenance Plan for the Historic Immigration Station, currently home of the U.S. Immigration and Customs Enforcement Facility, was prepared by MASON under contract with Solv LLC. Fieldwork was conducted by the historical architects at MASON in October and November 2018 to determine existing site conditions and to provide the Building Analysis portion of the report. Historical Architect, Joy Davidson, met with onsite maintenance staff and the mainland-based facility manager to discuss current and ongoing maintenance issues.

Previous reports on the condition of the facility, the original architectural drawings, as well as the National Register Nomination form (NRHP), were consulted for background information. The Recommended Treatment section itemizes preservation maintenance, repair, and building upgrades according to location. They are also assigned a priority.

Additional recommendations, regarding whether these activities may require no further Section 106 consultation, if itemized and agreed upon in a formal Programmatic Agreement (PA), are provided. The final section, Programmatic Compliance, discusses the alternative options for complying with the National Historic Preservation Act (NHPA) including the implementation of a PA.

Appendix B includes basic plans of the three historic buildings addressed in this report. The plans show where original building fabric remains and where modifications have taken place over the course of time. The original 1932 design plans along with subsequent renovation plans were consulted to make these determinations.

Introduction The Historic Preservation and Maintenance Plan for this Immigration and Customs Enforcement (ICE) facility will accomplish several objectives. It will identify important character defining features of the buildings. It will also provide a comprehensive plan to describe actions necessary to preserve the historic buildings, and it defines certain categories of maintenance and minor rehabilitation activities that may not require Section 106 review if the Historic Building Preservation Plan is adopted through a PA with the State Historic Preservation Division (SHPD).

History Hawaii has a history of immigration and for nearly one hundred years, immigrants arriving in Hawaii have had their initial processing in the area of the present immigration building at the entrance of the Honolulu Harbor. Hawaii’s polyracial society with its strong Asian strains is a result of the Hawaiian government and the sugar industry joining together to encourage and support immigration to these islands. By the middle of the 19th century, the Hawaiian population had declined drastically through high mortality, low fertility, and the dispersal of young men from the Kingdom on whaling cruises and seeking fortunes in the California gold fields. In the one hundred years from 1850 to 1950, over 350,000 labor immigrants were brought in to supply workers for the plantations and to augment a declining population.

In 1852, the first group of 200 Chinese labor contract immigrants was brought to Hawaii to work in the sugar plantations. New laborers were sought from China because the earliest sugar growing and milling operation on the islands had been Chinese. The Chinese, predominately single males, came in two periods, between 1876 and 1885 and 1890 and 1897. The next major ethnic group to be brought in as laborers were Portuguese families from the Azores and the Madeira Islands.

Japanese began to come in large groups after the signing of a convention between the two governments in 1886 and continued through the first decade of the 20th century. During these years, several other ethnic groups came in smaller numbers. The last major ethnic group, the Filipinos, came from 1907 to 1930 and again at the end of World War II, in 1946.

In the 19th century, immigrants came over the channel wharf to be processed at the pavilion and quarters of the Kingdom’s Quarantine and Immigration Depot built in 1879 on what was popularly called Fisherman’s Point. King Kalakaua, who personally initiated Japanese immigration in a visit to the Emperor, visited the station to greet the initial group of Japanese laborers arriving in 1886.

The United States government took over immigration matters after annexation and built a large new structure out over the mud flats which was opened July 4, 1905. The land was ceded to the United States by the Republic of Hawaii under the Joint Resolution of Annexation on July 7, 1898. Under provision of that Resolution and subsequent acts, the land must be returned to the State when it is declared surplus.

Designed by O.G. Traphagen, the first immigration building was light and airy – open to the roof and enclosed by walls of glass.

This building suffered extensive termite damage and was removed. The present U.S. Immigration Buildings were built on the site of the 1905 building and the site of the earlier immigrant arrivals over the channel wharf. In 1934, Herbert C. Cayton (as the designer of record under Charles W. Dickey) designed the five-building U.S. Immigration Complex consisting of the Administration Building, Garage and Waiting Pavilion, Lounging Shed, Detention Building, and a Gardener’s Cottage;

all in what is now considered Hawaiian Style architecture. Four of these buildings exist today. Three of them are owned by the Federal government and occupied by the ICE agency. The Gardener’s Cottage was demolished and the fourth building (originally the Detention Building) is on a separate land parcel which is owned by the State of Hawaii and operated by the Department of Health. That building is not part of this report.

595 Ala Moana Boulevard

Because the previous Traphagen-designed building suffered such extensive termite damage, the 1934 facilities were designed using only non-wood building materials: steel structures enclosed by terra cotta walls and roofing, with all metal doors and windows.

ICE operates three buildings of the original five-building complex: the most prominent- the Administration Building, the Lounging Shed directly to the rear of the Administration Building, and the Garage and Waiting Shed to the north. Each building has a characteristic high double-pitched tile roof. The remaining buildings each reflect their own individual function but relate to each other by scale, texture, and form. An interview with C.W. Dickey on July 27, 1934 in the Honolulu Star- Bulletin best describes the design intent of the complex in the architect’s own words:

“In designing the new immigration station buildings the main objective was a group of buildings expressing the spirit and environment of Hawaii and at the same time maintaining well balanced and well-proportioned masses, graceful lines, and a pleasing color effect.”

“This meant a wide departure from the more or less stereotyped stations of the mainland and it required no small amount of persuasion and diplomacy to get a design accepted…”

“In general the buildings consist of low lying masses of cream colored stucco walls surmounted by graceful sloping roofs of variegated green and russet tiles.”

“The administration building facing the Ala Moana has a long shallow court on its main front, with a lofty entrance portico treated with a touch of Chinese architecture in its detail, which is accented and enriched with polychrome terra cotta. This portico is the most important architectural feature of the group and is entirely of terra cotta with polychrome ceiling in acoustical terra cotta, a floor of varied shades of dark red and brown Roman Travertine and a striking aluminum grill across the inner wall. In the center of the floor is a large bronze many pointed star showing the directions to all the principal ports of the Pacific.”

During World War II, the Administration Building was used as a temporary detention facility manned by the United States Army and the Federal Bureau of Investigation (FBI). Detainees were 75 percent Japanese, but also included German, Italian, Hawaiian, Portuguese, and Chinese. According to sources, authored by internees based on their own experience, nearly 200 men were housed dormitory style with minimal sanitation facilities. They were guarded by armed military police and given little access to exercise or the outdoors while they were processed out to other long-term detention centers.

595 Ala Moana Boulevard

Documentation of Significance In 1973, the complex was listed on the National Register of Historic Places (NRHP), under the name “U.S. Immigration Office.” At the time, the complex consisted of four buildings because the Gardener’s Cottage was removed prior to the nomination. The complex was considered significant for its association with celebrated Hawaii architect C.W. Dickey, but it could be significant for its role in the overall immigration system in Hawaii.

In 2014, a special resource study and environmental assessment was issued by the National Park Service (NPS) which identified the Honouliuli Internment Camp and the U.S. Immigration Station as nationally significant for their central role as internment sites in Hawaii during World War II. Unlike Honouliuli, the Immigration Station was determined to not be feasible as an addition to the national park system because it is currently in active operation by the Department of Homeland Security and the State of Hawaii Department of Health.

Building Analysis Main Building; Building 1 (Former Administration) The former Administration Building is the most prominent facility on the site. It is an H-shaped building with hip roofs and a floor area of approximately 19,000 square feet. The center portion is a two-story space, and the side wings are single-story.

The structure is steel frame with reinforced concrete floor and roof slabs. The roof is framed with structural steel clear-span trusses supporting a sloped concrete slab. Steel columns are typically located around the perimeter of the building and at the central corridor. They are encased with hollow-tile pilasters and exterior masonry. The exposed exterior rafters are formed concrete cantilevers extending from the concrete encased perimeter steel girders.

Roof and Roof Drainage The double-pitched hip roof is covered with terra cotta tiles. The gablets have vents constructed of the same barrel-shaped roof tile. The roof deck is formed concrete with the elements that appear as exposed rafter tails which are integral parts of the deck (Photo 4 & 15).

The building’s roof drainage system consists of copper gutters, collector boxes, and downspouts. Historically, the collector boxes were located only on the central, two-story section of the building, both front and rear facades. The leaders from the gutters on the rest of the building went directly into the wall with no collector boxes. Some of the collector boxes are extant, but the leaders going into them have been sealed so that the water in the gutter is directed to other downspouts which terminate at ground level. This was done because the internal drainage system clogged over the years and caused water damage within the building. Repair of the internal system was not viable without destruction of original wall material so re-routing the water to an exterior drainage system was preferred.

In a couple of locations, the historic round downspouts have been replaced with square downspouts. Some of these downspouts are not in the original configuration. This leaves unconnected collector boxes hanging on the walls with no downspouts. The leaders have been removed in most locations where they went directly into the building. The historic downspouts lead into the walls, but it is not known where the pipes go once out of the walls.

Photo 4: Front of Main Building (Former Administration Building) 2018

Exterior Walls The majority of the exterior walls are single-story, about 13 feet high, concrete, and 8” concrete block with a stucco finish. There are some larger cracks in the stucco on the back of the building at the lanai, where the detention cells are currently located.

Some hairline cracks are visible in other locations, mostly where the new downspouts are connected to the wall. The rear façade of the central two-story section is also finished with stucco and has a decorative band of terra cotta tiles, which aligns with the second-floor window sills.

The central, two-story section of the building is constructed of terra cotta blocks over a concrete and steel structure. At the entry elevation there are large openings created by terra cotta finished columns and decorative beams (Photo 6) with a large grille of terra cotta blocks in the wall space on each side of the opening (Photo 5). Bronze, Art Deco style letters say “Administration Building” on one side and “United States Immigrant Station” on the other. At the top of this same entry wall, the terra cotta blocks have a glazed decorative geometric pattern.

In August 2018, the potentially dangerous Hurricane Lane threatened Oahu. Out of caution to protect the historic buildings, all of the windows were boarded up with plywood resulting in an extensive amount of screw holes in the exterior walls which have since been patched and repainted.

Interior Walls The interior walls are primarily constructed of terra cotta tiles.

The Lobby and Corridor wall finish is glazed terra cotta blocks.

The wall finish in the administration spaces is smooth plaster.

The wall finish in the restrooms is also smooth plaster with a marble wainscot. All of these finishes are historic character-defining features.

The terra cotta tiles at the Lobby walls have the same texture as the exterior walls. The Lobby is a two-story space, so the walls extend the full two stories. These walls have tile grillwork at the second-floor level on either side, and columns with decorative metal grilles fill in the back wall of the Lobby at the second floor. The Ala Moana (east) side of the Lobby has the same decorative beams with terra cotta finish as the building exterior.

In the corridors, the terra cotta finish continues flush to the base with the bottom tile having a small cove transition to the ceramic tile floor. Open grilles, constructed of terra cotta blocks with the same finish as the solid walls, are at transom height along most of the corridors (Photo 10). Historically, the grilles had metal screens on the interior; however, many of them are covered with gypsum board, wood, plastic, or glass on the room side. All of the grilles are extant. Travertine arches in the main corridor divide the entry and office areas of the corridor. In some areas of the corridors, the terra cotta block walls have cracks at the joints due to building settlement.

The offices in the Ewa (north east) wing have decorative plaster crown molding painted a contrasting color. Two offices, Rooms 102 and 103, which were historically the District Director and Secretary offices, have geometric-patterned cornice moldings painted a coral color (Photo 7). These rooms are in the same configuration as indicated on the 1932 drawings, and the drawings call out for a cornice in each room. The third room with a decorative cornice is not in the same configuration as shown on the 1932 drawings, but it appears to be a portion of what was a larger room that has been divided into two rooms.

Throughout the building there are other interior character defining features such as original bulletin boards, recessed firehouse cabinets and the bronze compass recessed in the Lobby floor.

Metal Grille Work & Gates To provide an open feel along with security, the original design of the building included metal grillwork and gates in several locations in the building. Historically, the lobby was open at the front with the existing metal grillwork as the wall between the Lobby and Corridor and between the Lobby and the overlooking second floor (Photo 8). A metal gate provides access between the Lobby and the first floor Corridor. Since the original construction, the Lobby has been somewhat more enclosed and secured further with the addition of single-story metal gates along the front, in the plane just behind the columns (Photo 8).

Other areas of metal work within the building include: two pairs of gates within the travertine arches in the main corridor on either side of the lobby area and an exterior pair of metal gates over plate glass doors (Photo 9). The latter provide a private entrance to what was historically the District Director’s office.

Also, at the back of the building, non-historic panels of expanded metal mesh, which are painted to match the exterior wall color, have been inserted between columns to enclose the two lanai.

Photo 9: Aluminum Gates at Ewa Wing

Doors and Door Hardware Historic doors throughout the first floor include single-lite hollow metal doors with operable transoms (Photo 10). Both the glass in the door and the transom glass are commonly historic pyramidal glass. Security bars have been installed over the lite in a few of the doors. Historic second-floor doors, as well as utility and toilet room doors on the first floor, consist of flush, hollow metal doors; most of which remain.

One other pair of historic doors leads from Room 102 to the front lawn. These are large glass doors with decorative aluminum grille work over the glass (Photo 9).

Only a few alterations involving doors have occurred. One door was added on the Ewa (north east) side to provide an additional exit and accessible access to the building. A window was removed to install the door. Other alterations include modification of the historic sliding doors on the side walls of the lobby. The openings on the Waikiki side have been filled with an aluminum and glass storefront system. Also, at least one door leading from the corridor to an office has been replaced with an aluminum storefront door.

The historic door hardware consists of rectangular escutcheons with beveled edges and egg-shaped knobs all with an unpolished brass finish. Many doors also have a deadbolt in the escutcheon.

Historic doors also have ball-tipped hinges with an unpolished brass finish. Some door hardware has been replaced with more contemporary aluminum knobs and deadbolts. Security keypads and card readers have also been installed on several of the corridor doors.

Windows The majority of the windows throughout the building are historic aluminum-framed pairs of casements, some of which have an awning-style window above the casements and some have a hopper-style window below the casements (Photo 11). Most of the windows have metal trim around the jamb and head and terra cotta sills on the exterior. Reflective film has been added to the windows. The majority of the window hardware is original aluminum lever-style handles, along with casement operators and hinges.

Ceilings The majority of the ceilings throughout the corridor and office spaces have a smooth plaster finish. In some spaces, the smooth plaster has been covered or replaced with a textured finish. Two rooms (rooms 102 and 103) have slightly stepped ceilings with decorative plaster elements and crown moulding. The historic Lobby ceiling is a coved, decorative terra cotta tile ceiling in a geometric pattern (Photo 12). This ceiling tile is hung from a steel structure which can be accessed through a panel on the second floor.

Some office ceilings have been lowered by installing acoustical ceiling tiles. Some are lowered to below the head height of the windows. This was likely done to provide space to conceal electrical or mechanical systems. Acoustical ceiling tiles have also been applied directly to the plaster ceiling in some spaces.

595 Ala Moana Boulevard

Floors There are a few different historic floor finishes throughout the building. The most decorative historic floor is in the Lobby. The floor is covered with ceramic tile in a relatively simple geometric pattern with a travertine border. Also, in the center of the floor is an octagonal bronze compass plaque which denotes the distance to several locations surrounding Hawaii.

The first-floor corridor floors are also finished with ceramic tile, but in a simpler pattern (Photo 13). According to the 1932 drawings, the two rooms adjacent to the Lobby also had ceramic tile flooring; however, the floor is now covered with carpeting.

The second-floor corridor floors are colored concrete, scored in a geometric pattern including a border around the edges. The majority of the remaining floors are noted on the 1932 drawings as linoleum, but they are now covered with carpet. Utilitarian rooms, such as the electrical and janitors’ rooms, retain the historic scored-concrete floor in a natural concrete color. The 1932 drawings also call for terrazzo floor in the toilet rooms throughout the building, which has been covered with ceramic tile during a recent restroom renovation project.

The historic walls throughout the building retain a concrete base as indicated on the historic drawings. Most of the historic bases were noted as colored concrete, and the majority of them have been painted to match the walls.

Stairs Large, original travertine steps lead from the front lawn up to the front lobby and up to the entrance at Room 102. There is a contemporary landing, accessible ramp, and stair on the Ewa (north east) side facing the employee parking lot. Exterior steps that lead to the rear courtyard are concrete with no handrails.

There is one set of stairs to the second floor in the inside of the building; the stairs are built of colored concrete. The handrails are round unpolished bronze with balls at each end. A chair lift has been added to this stairway.

595 Ala Moana Boulevard

Electrical/Lighting The historic light fixtures within the building include large glass and metal pendants hanging in the Lobby (Photo 14) and sconces. The latter, in the same style as the Lobby pendants, are on the wall in the corridor adjacent to the Lobby (Photo 14).

Many historic globes are being stored in the attic space.

Office spaces have non-historic fluorescent fixtures; these include ones hanging from or attached directly to the ceiling as well as ones set into a dropped acoustical ceiling. Other contemporary fixtures include rectangular surface-mounted fixtures on the exterior walls of the building. Throughout the office spaces, raceways and conduits have been surface mounted to the walls as electrical outlets have been added.

Restrooms Both the men’s and women’s restrooms have been recently renovated to include new fixtures, finishes, accessories, and partitions. The only original feature that remains in the restrooms is the 6’ marble wainscot (Photo 14).

Miscellaneous Within Room 103, which is labeled on the 1932 drawings as the District Director’s office, is a vault (Photo 14). The walls around the vault are shown as concrete with a plaster finish rather than the typical interior walls constructed of terra cotta blocks. The door to the vault is a large steel door with a combination lock in the center, two large two-knuckle hinges with decorative tips, and a lever handle.

Alteration History A few alterations have been made to the Administration Building (Building 1) since it was constructed, including:

A window on the north side of the building has been converted to a door with an exterior landing, ramp, and steps

The windows have been tinted Originally, the lobby was open to the rooms directly to the north and south; walls have been built between those rooms and the lobby

A metal security screen has been installed at the front lobby entry

A few walls have been added to divide large office spaces

Walls have been added in the main west room on the second floor

Many of the rooms have had carpet installed and have had a texture of some sort applied to the ceiling

Most of the interior general overhead light fixtures have been replaced

Terrazzo flooring in the restrooms has been replaced with ceramic tile

Split Air conditioning has been installed Most of the interior grillwork has been covered with plywood, plastic, or glass due to air conditioning

Annex; Building 2 (Former Garage & Waiting Pavilion)

Roof and Roof Drainage The double-pitched, hip roof is covered with terra cotta tiles.

The roof deck is board-formed concrete with the pattern of the boards used to form it visible at the underside of the exposed eave.

The roof drainage system consists of copper gutters and downspouts. The original building had no roof drainage system.

Exterior Walls The exterior walls are one-story with a stucco finish. The rear of the entire building has small concrete grilles in each bay (Photo 17). All of the grilles are visible from the exterior of the building; however, some have been covered on the interior of the building and are not visible. Some have been covered in glass or other air barriers on the interior. Some of these grilles have been cut and window air conditioners have been installed in them (Photo 21).

The historic open bays on the front side in the original garage portion of the building have been filled with recessed infill partitions and are finished in a similar manner to the historic stucco. A narrow, fenced area has also been added to the front of this portion of the building. At the taller section of the building, which was originally the Waiting Pavilion, there are three open bays at the front delineated by two columns and solid walled bays on the sides. Within the solid walls are large, decorative concrete grilles. At the Ewa (north east) end of this building, the original concrete grille remains in the front wall.

Photo 17: Annex, Former Garage

595 Ala Moana Boulevard

Interior Walls The restrooms, which retain their historic configuration, are located in the taller, Diamond Head section of the building. The only permanent, historic interior wall is the wall between the men’s and women’s restrooms which has a marble wainscot and smooth plaster finish on the upper wall (Photo 23). The marble toilet partitions align with the wainscot and are also character defining features of the building. The interior walls in the central portion of the building are primarily modular office partitions which are not fixed.

Doors Because this building was designed with mostly open bays in the garage and pavilion sections, it was built with few doors, and all of them were exterior doors. The existing doors which are likely historic are hollow metal, flush doors with a single-lite in all except those leading to the restrooms. The extant historic door hardware consists of rectangular escutcheons with beveled edges, plus handles with thumb latches (Photo 19). The doors in the infill walls are flush metal.

Windows Historically, this building did not have windows. The windows installed in the garage bay infill walls are contemporary aluminum sliding windows.

Ceilings The ceiling in the restrooms and open garage area in the large side section is open to the concrete structure. The ceilings in the central section are either exposed structure or suspended acoustical ceiling.

Floors The bathroom terrazzo flooring is a character-defining historic feature of the building. As an open garage, the remainder of the building had a concrete floor historically.

Electrical/Lighting There are no remaining historic light fixtures in this building.

Contemporary rectangular surface-mounted fixtures have been added to the exterior walls of the building. Raceways and conduits have been surface mounted to the walls throughout the office spaces.

Plumbing Fixtures Most historic plumbing fixtures and toilet room accessories are extant. These include white, porcelain pedestal lavatories with a tapered square leg, standard flush valve toilets and urinals, and metal pedestal soap dishes mounted on the lavatories.

Alteration History The Former Garage and Waiting Shed (Building 2) has been altered since it was constructed. The alterations include:

The open garage bays that were in the center section of the building have been enclosed and are being used as office space A chain-link cage has been constructed on the parking lot side (Photo 20) Window air conditioners have been installed, damaging the historic grillwork (Photo 21)

Investigations; Building 3 (Former Lounging Shed)

Roof The double-pitched, hip roof is covered with terra cotta tiles.

The roof drainage system of the building consists of copper gutters and downspouts. This drainage system is a contemporary addition, since the original building did not have a drainage system.

Exterior Walls The exterior walls are one-story with a stucco finish. Some hairline cracks in the stucco are visible in various locations.

There are some larger cracks in locations where the downspouts are inside the walls. On the back side of the building is decorative grillwork (Photo 24). All of the grilles are visible from the exterior of the building; however, some have been covered on the interior of the building and are not visible. Others have been covered in glass on the interior. The historic open lounge area of the building has been enclosed with infill walls recessed from the columns so that the columns appear as pilasters. The recessed walls are finished in a similar manner to the historic stucco.

Interior Walls The interior walls of the building are primarily modular office partitions which are not fixed.

Doors Because this building was historically an open lounge, the only doors were to the restrooms, and both were exterior doors; now, due to the enclosure of the lounge area, the historic restroom doors are no longer exterior doors.

Windows Historically this building did not have windows. The contemporary windows in the infill walls are fixed aluminum.

Alteration History The Lounging Shed (Building 3) has been significantly altered since it was constructed. The alterations include:

The large lanai, which was the main space of the building, has been enclosed with solid walls finished with exterior insulation and finish system (EIFS) and large aluminum windows.

The columns are expressed on the exterior of the building.

595 Ala Moana Boulevard

Overall Site With the exception of the deep front lawn facing Ala Moana, and the courtyard behind the Administration Building, a great deal of the site is currently paved and used for parking. A carport and two temporary shade structures have been installed in the rear parking area. There is a fountain and decorative rock path in the rear near the Lounging Shed.

Recommended Treatment The following list of preservation maintenance, repair, upgrades, and modifications are listed to propose potential high, medium, and low priority and routine actions that will not require additional Section 106 consultation if these actions are itemized and agreed upon in a formal PA (See next section on Programmatic Compliance) and executed in accordance with the Secretary of the Interior’s Treatment of Historic Properties. Priorities are based on general maintenance typical of any facility as well as preservation of historic character defining features and original building fabric.

Routine priorities include actions that may be undertaken to maintain the facility in its existing state or to prevent further damage to the facility. Routine priorities are general maintenance and would not involve any physical disturbance to historic features of the building, and would include tasks such as cleaning, inspecting, repainting, in kind replacement of non-historic features. High priorities include actions that may be necessary to prevent damage to the facility over time, including repair or in-kind replacement of features of the building that may be historic without altering the physical appearance of the building. Examples of high priority actions may include replacing roof tiles in-kind, repairing cracks in stucco, maintaining historic features in good working order, and other actions intended to preserve and maintain the integrity of the building and historic features. Medium and low priority actions include actions that may be undertaken to meet future operation and facility needs. Medium and low priority actions include maintaining historic features, replacement in-kind of weather-stripping, caulking, etc.

Additional information regarding this type of compliance is discussed after the treatment tables below. The proposed upgrades and modifications are not required but may be implemented over time in accordance with the requirements described in the following table.

Additional information regarding this type of compliance is discussed after the treatment tables below. Until a formal PA is executed, all modifications to the property are subject to Section 106 consultation.
