AbstractThe Portland Ecological Aquatic Center (PEAC) is a public oriented research facility for aquatic habitat in the Pacific Northwest. The project brings together Portland’s Eastbank with the Willamette River and public interation with aquatic research. PEAC is pecifically focused on the synthesis of research and habitat restoration along the rivers edge intertwined in public education and interaction. Providing points of respite along the esplanade, carving an eddy to bolster salmon habitat, and managing the dischare of water into the river, PEAC demonstrates how to implement a place that enhances the natural and built environment in urban areas. The site is located between natural (Willamette river), built (the I-5 expressway) and artificial environments (proposed water management marsh and slow current eddy). The building, read in series, is composed of related objects connected in a row; each taking on a different aspect of an ecological aquatic center.

Critical IssuesInstitution for interactive and all encompassing learning.Harmony between traditionally separate elements: Portland Eastbank/River and Public/Research.A unique building for Portland’s waterfront.Controlling and containing water runoff on the site to not add to the Willamette’s downtown flooding.Providing space for migrating salmon to develop in a slow current area.

Urban/Site contextThe Marquam Crescent (located on Portland’s east bank between the Hawthorne Bridge and OMSI) is the waterfront edge of the southeast industrial area. This industrial area creates a gap between central city/downtown and residential neighborhoods. The site bridges this gap but is currently under utilized, mostly vacant and surface parking. This project adjacent to OMSI and in conjunction with proposed boat house, library, and schools creates an interactive learning district with the new Innovation Quadrant. The creation of the PDC Innovation Quadrant , great ac-cess to the water, OMSI / IMAX, and new Portland Milwuakie Light Rail bridge are turning this area from an under used, abandoned, urban area into a key attraction in Portland.

Proposed Concepts [site and building]PEAC highlights the Willamette River in Portland; a perfect confluence of river, urban infrastructure, post-industrial area, artificial shoreline, and pedestrian traffic. Mimicking the curving riverbank just as the city does, PEAC expresses the connection with the water in a project that proves a mutually beneficial environment between built and natural space. As part of Portland’s waterfront scene with; views of habitat: natural, restored, and artificial PEAC a prominent building and an ecological urban site with downtown as its backdrop.

Exhibitory and Participatory ExperimentationPEAC both highlights and ties together many pieces. Advocating a more critical approach to zoological experience by revealing the whole pro-cess for complete understanding. Presenting a variety of components of aquatic study: from field observation and laboratory research to experi-mentation and communicating findings.

DESIGN SUMMARY

Explanation of ProposalThe site is carved out to make spce for an eddy along the river. The protected shore and slow current area benfits migrating salmon. The built space here is weaved around and between the infrastrucure of the elevatated I-5 expressway. Access to PEAC is along the extension of both SE Clay St and SE Stephens St that become pedestrian paths ending in elevated platforms with views of downtown, the bridges, and new shoreline. The Eastbank Esplanade running through the site creates opportunities for traffic to stop and rest. A piece of the existing warehouse on site is converted into a picnic plaza with a cafe and water fountain for children to play in. Boardwalks branching off from the Esplanade take visitors through a remediation marsh and out to a platform on the peninsula that puts you on the water. The Marquam crescent is an example of how to merge the natural and built environments. From the parking lot storm water management to the Marquam Inlet, differing examples of recre-ated habitat, human access to the water, and wildlife only areas are expressed.PEAC is organized as a series of angular blocks (one for each major programmatic element) in sequence. To experience the collection as parts and a whole the entrance is located in the second block reached by walking underneath the first block and up an open-air stair that doubles as seating to watch the river. Numerous cut-outs in the floor and double height spaces allow for patrons to see activity on multiple levels. This diagonal visual connection is experienced immediately upon entry with the cafe balcony above and the sound of the life support systems from below. The blocks are in sequence based upon the level of openness and natural light required per the major program: Interpretive center, Event Lobby, Large Tank, Research labs, Behavioral Enclosure, and Terrace. An interstital space highlights the separation of each block. Each successive space is reach by passing through one block into a narrow atria: bathed in natural light, providing a view of the river, and offering relief from the activity within each block.

The project is essentially six individual buildings adjacent to each other, strengthing the discrete identity of each block. Large Vierendeel trusses span the edges framing each block. This allows for an open uninterrupted space and circulation within the building. Transitioning from one block to the next patrons must pass through a screen similar to the exterior facade and cross a grated catwalk before passing through the next screen into the next block. This interstital space acts as a relief from the activity happening with each element of the program and helps to reori-ent them with the river and downtown. The deep beam supporting the northern blocks allows for differing experiences along the esplanade: shady under the Marquam Bridge, covered refuge under PEAC, and great views between PEAC and the river.

The PEAC’s facade enforces the concept of different elements in a larger whole. The envelope is layered with a typical rainscreen (color coded to each program block) behind perforated copper screens. The copper panels are arranged in four sizes with a six inch gap horizontally and flush vertically. Corresponding to the activity inside each block, the grade sloping to the water farther north, and the transparency of the program in each block the average panel size decreases, therefore, increasing the number of gaps and the amount of daylight that enters the building. Separated by glass curtain wall interstitial spaces each block is simultaneously distinct and read as part of the series.

The major environmental focus is water management. PEAC (both building and site) work as a filter for water before getting to the river. Ninety percent of freshwater aquatic activity happens along the waters edge, the shoreline is also the last and major place vegetation traps and absorbs polluted runoff. The eddy and increased shoreline not only benefits salmon but enhances the water quality. The peninsula also protects the bank from boat traffic giving vegetation a better place to thrive. The surrounding parking lots have bioswale medians but that is not enough in the rainy season. The marsh east of the building can absorb any excess runoff during high precipitation periods. Not only saving surface storm water from the Big Pipe but also runoff from the expressway. Excess water from these sources flows under the glass transitional spaces of the building through filters before being released into the Willamette.

SITE SIZE approx. 3.9 ACRES

PEAC builds upon existing attractions (OMSI, Rose Garden, Lloyd Center) near the eastbank esplanade.

Traffic flows with & crosses the river but the river is not the destination.

PEAC is sited along both the downtown river walk and public transit.

SITE - Context / Neighborhood Profile

The south end of the central reach could bridge gaps between central city/down-town and residential/neighborhoods with a industrial district. The site between the Marquam Bridge and Ross Island Bridge could help spur development in much of the now vacant south waterfront land and would have great public access with the new Portland-Milwaukie light rail bridge. This location near OMSI and the Opera House also creates an interesting museum district with potential to revitalize under used, abandoned, or blighted urban areas. The crescent site adjacent to OMSI also benefits from the strong connection with the IMAX theater.

The Flint Riverquarium by Antoine Predock focuses on a Blue Hole ( a geological fea-ture of southern Georgia where the water stays a constant 68 degrees). The design can be described, “as if the Riverquarium had risen around an untamed condition” - Alemar. The building is off the water to stay clear of the 100 and 500 year flood plains that damaged much of the town with a 4 year stretch.

PRECEDENT Program - Quai du Chatelet, Orleans, FR

The river Loire which lost its status as a waterway due to navigability had turned into an abandoned urban purlieu with little relation to the city. UNESCO named the Lorie Valley as a natural and cultural world heritage and changed Orleans ideas about the river from turning its back on the water to embracing it. The Loire Green Grid proj-ect was founded to use natural and built potential of the valley to increase tourism and relationships with the river. The main implementation is a 25 meter wide prom-enade park.
