PIER 62/63 SCHEMATIC DESIGN

PIER 62/63 SCHEMATIC DESIGNThe existing 1.7-acre Pier 62/63, which is in need of structural retrofitting, will be demolished

to make way for a new 1.5-acre Pier 62/63. The new pier will be reshaped and will contribute

1.5 acres to the largest contiguous public open space within the Core project Area. Pier 62/63

will be surrounded by water on its southern, western, and northern sides. Neighboring sites

include the future promenade and Overlook Walk to the east, the Seattle Aquarium to its south,

the Waterfront Landing condominiums to its northeast, and Bell Harbor Marina to its north. A

gangway and floating dock is proposed to connect to the southern edge of Pier 62/63 which will

support direct boat access, as well as serve as moorage for a future pool barge (refer to the

Pool BargeSchematic Design Report, January 2014).

SITE PLANThe proposed Pier 62/63 site will be a wide open pier with a slightly smaller footprint than the

existing pier. The northern edge of the new pier aligns with the existing northern edge, while

the southern edge is re-configured to align with the future Overlook Walk. The alignment of the

southern edges of Pier 62/63 with the Overlook walk is to draw a site line out to this very open

part of the Central Waterfront. The features of Pier 62/63 include:

36,000 square feet of flexible open space adjacent to the promenade;

5,800 square feet of flexible open sapce on the western end of the pier;

Long stepped seating area along the pier’s southern and western edges; and

Canopy structure along the pier’s northern edge.

Gangway and Floating Dock

Details of the site grading, program, and architecture are discussed in the subsequent sections.

PIER GRADING & DRAINAGEThe surface deck of the proposed Pier 62/63 will tilt up gently from the promenade level (+16.3’)

at a grade of 1.7% (no more than a typical sidewalk cross slope), to a high point of +21’. Along

the southern edge of the pier the surface deck of a 15-foot wide walkway will gently tilt down

from the promenade level towards the water at 1.2% to a low point of 15.7’. The opposing tilts

creates a 5.3-foot differential at the western end of the pier allowing the introduction of south-

and west-facing seating steps built into the pier structure. At the western end of the pier these

grade changes result in a drop of 5.3 feet between the high point and low point, which will be

mediated by seating steps, built into the pier structure. The upper surface will drain to surface

runnels and the lower surface will sheet flow to Elliott Bay with means to capture and treat

water if needed.

(Note that the drawings in this schematic design report reflect this 5.3 feet height difference.

However the technical drawing set reflects a previous version wherein the difference between

the high point and low point was 7 feet. The technical drawings will be updated in the next

phase to reflect the desired 5.3’ height difference.)

Pier 62/63 is a “blank canvas” allowing maximum flexibility, accommodating maximum weight

loads, with the ability to introduce large footprint rotational elements programmed through

the year. The piers’ peninsula-like quality lends itself to temporary, partial or full fencing off

for events. Below is a summary of the areas and their programmatic potential:

Promenade The promenade, 16 feet wide in this location, will serve as the entryway for

pedestrians and any maintenance or event vehicles into the pier. Because it is one of the

narrowest parts of the waterfront promenade, the eastern edge of Pier 62/63 is kept free from

obstructions, to allow pedestrians to spill over into the pier.

Aquatic Habitat Interpretation The underwater area between the Aquarium and Pier 62/63

will be one of the aquatic habitat improvements areas being built as part of the Seawall Project.

Therefore the area between Pier 62/63 and Overlook Walk are envisioned as sites for education

and learning about the aquatic habitat beneath. Details of these elements are discussed in the

next section.

Central Flexible Floor The upper level of pier 62/63 will be kept relatively open and flat to

enable a wide variety of programs (i.e. roller skating, beer garden, movie screenings, concerts,

food trucks, etc.). See Appendix B for scale comparisons for various program types.

Get-Down/Grandstand A long edge of bleacher seating will flank the southern and western

edges of Pier 62/63, which will serve as a wonderful place to sit and watch the sunset, fireworks,

boats, etc. At the western end of the pier, which looks out onto the expansive Elliott Bay, a

larger space lends itself to small performances, fishing, informal play, etc.

Canopy A linear canopy structure is proposed for the north edge of the pier, which will have

several functions: 1) Covered ciculation & seating spine, 2) Flexible Covered space for “plug

and play” activities, utilities, lighting, storage, and program support, 3) Roof acts as viewing

platform to view the pier, pool barge, Elliott Bay, and the City. Further programmatic functions

of the canopy structure is discussed in the Architecture section.

Aquatic Habitat Concerts

The north, west, and southern edge of Pier 62/63 is an open water edge, flanked by a railing

along which visitors can lean and view the water and Elliott Bay beyond. Boat moorage along

the pier will likely occur on the southernside of the pier. The northern side of the pier faces Bell

Harbor Marina, is an unlikely location for boat moorage, as all existing boat traffic in and out of

the marina is already constrained by the 105-foot wide throat between Pier 62/63 & the marina

docks. The western edge of the pier is 138 feet long and could accommodate boats up to that

length, however it is the only unobstructed view across the Bay. Along the southern edge of the

pier, a boat launch - consisting of a gangway and floating dock held in place by mooring piles

- is proposed. The gangway and mooring piles would also service the proposed pool barge (a

separate project).The pool barge will be seasonal and would be brought to another location in

the off-season, allowing the southern side of the boat launch to be used for other uses (tall

ships, seafood sales, etc.).

HABITAT WALL & INTERPRETATIONThe underwater area between the Aquarium and Pier 62/63 will be one of the aquatic habitat

improvements areas being constructed as part of the Seawall Project. At low tide an aquatic

“bench” will be exposed, as well as the custom-made seawall texture, which clads the face

of the seawall, beneath the promenade. To celebrate these habitat enhancements features,

the railing immediately adjacent to the habitat area is proposed to be mounted with habitat

interpretation signage, as well as a seating area for gathering. Across the promenade, along

the retaining wall which follows the seam between Pine Street and the Overlook Walk, the

custom-made seawall texture will be mounted to the face of the retaining wall to make visible

what is happening beneath the promenade.

* Note the railing and interpretive signage is included in the Pier 62/63 project limit, but the

Retaining Wall w/ Tideline Habitat Wall is within the promenade project limit.

FISH CLEANING TABLE


PAVING & FURNISHINGSPAVING The upper and lower Pier 62/63 deck surfaces will be constructed of pre-cast concrete

panels, with a concrete topping layer into which the baseline patterns established as part of

the Main Corridor paving concept will be expressed. Concrete is a relatively low maintainence

non-slip surface. Maintenance of the pier surface will be especially important after large

events which may create excessive dirt and debris. A non-slip surface is important during

large storm events which can cause seawater spray, as well as “wet” off-pier uses such as

kayaking, swimming, and fishing.

FURNISHINGS The primary seating area will be the seating steps area along the southern

and western edges of Pier 62/63. The bleacher seating, as well as the free-standing benches,

will be made of wood, with detailing similar to that of the Promenade. A small cluster of

seating stools will line the interpretive habitat railing at the southeastern corner of the pier.

A fish cleaning table/sink is proposed for the northwestern corner of the pier, which will be

connected to potable water. Finally a railing similar to Union Street Pier will surround the pier.

PRECEDENT Ballard Library, Seattle PRECEDENT Flenderhaus, Vienna, Austria

PRECEDENT Quai Jacques Cartier, Montreal

OVERVIEW The architecture on Pier 62/63 has evolved from Concept Design, which proposed two

distinct and separate kiosk structures on the pier, to a single, continuous structure along the north

side of the pier, presented in this Schematic Design report. The canopy structure will comprise

three separate and distinct elements: (1) the structural frame, (2) a continuous viewing platform,

and (3) the program enclosures.

STRUCTURE The open steel frame allows for views though the structure, and is comprised of a

12-foot long by 12-foot wide by 12-foot high structural module repeated over the entire length of

the structure. Layering of structural members is expressive of post & beam construction. The

light masts are steel pipe columns integrated with the structural frame, and occurring every 24

feet for the length of the structure.

VIEWING PLATFORM The upper level viewing platform will be accessed from stairs at the east

and west ends of the canopy structure, or from a vertical platform lift near the east end. The

decking is composite wood, with the perimeter enclosed by a cable guardrail.

LIGHTINGThe lighting for the Pier 62/63 will provide a rich nighttime environment for waterfront visitors,

while providing design continuity with the adjoining promenade and Alaskan Way and adjacent

Overlook Walk. The lighting aims to provide: 1) wayfinding function, 2) accent lighting to

delineate grade changes, and area lighting for large events.

A continuous light along the underside of the perimeter railing will draw visitors in and around

the entire pier. Along the southern ramp towards the western edge of the pier are a scattering

of in-grade marker fixtures, increasing in frequency from the beginning of the pier ramp to the

east and reaching maximum frequency at the west end of the pier.

IN-GROUND LIGHTINGMAST LIGHTINGACCENT LIGHTING

Accent lighting is provided along the seating step risers, stairs, and long benches along the

southern and western pier edges. This lighting helps to provide clear definition of the grade

separation between the upper and lower portions of the pier at night.

Along the canopy structure will be a series of masts mounted with lighting which will provide

illumination for the large flexible event space at night.

The project will utilize LED technology wherever possible to ensure safety and security of

waterfront users, maximize energy conservation, and contribute to operational efficiency.
