Flood Resiliency: A Green Infrastructure VisionCouncil Bluffs, Iowa

The Missouri River is North America’s longest river and serves an important role to the community - both environmentally and economically. Back to the River (BttR), a multi-dimensional foundation focused on enhancing the ecological, recreational, and historical corridor along the Missouri River in Nebraska and Iowa, has a long-standing dream of the river becoming the heart of adjacent communities. That dream is being realized through the combined efforts of public and private sponsors, who recognize a balance between the Missouri’s historically-recognized value as a commercial waterway and as an important natural habitat.

Amidst, the positive change came the Flood of 2011 - bringing unprecedented flood levels and extensive damage. Submerging the River’s floodplain for nearly four months, the 2011 Flood changed the River’s landscape in completely unexpected ways. Compounding damages from the 2011 Flood, defunding of the Missouri River has occurred for the third consecutive year, both contributing to the heightened need of a coordinated Restoration | Recovery Plan along the river. In order for Council Bluffs to assess the damage and plan for the River’s future, a partnership developed, resulting in an integrated systems approach to community planning and urban design.

The multi-jurisdictional flood map captures both sides of a 64-mile stretch from Mondamin, Iowa and Herman, Nebraska to the mouth of the Platte River and informed discussions between UN-L College of Architecture and Back to the River in determining an appropriate vertical, interdisciplinary studio project site. Council Bluffs, IA was chosen as the project site from this discussion resulting in a partnership between UN-L College of Architecture, Back to the River, and the City of Council Bluffs, Iowa.

Community Engagement ProcessBuilding Community Capacity

The ProcessIn fall 2013, during my 5th year, I participated in a four phase vertical, interdisciplinary service-learning studio partnered with Council Bluffs, Iowa to assess and develop a strategy for Council Bluffs development post flood. During this fifteen-week interdisciplinary service-learning studio, a four-phase process engaged stakeholders and students in a reciprocal partnership where both are teachers and learners, thus building capacity in the community and studio. The four phases included establishing the partnership, gathering principle based inventory for analysis, developing a green infrastructure framework plan, and designing prototypical projects.

The PartnershipA relationship between Back to the River (BttR) Foundation and Sasaki led to this studio. BttR strives to preserve and improve wildlife habitat and provide economic development opportunities in a balanced, sustainable manner along the Missouri River. Stakeholders from all over came to the meeting to partake in a visioning session allowing the partners and students to define a process. Some of these partners included:

Back to the River Foundation, Council Bluffs Parks and Recreation, Council Bluffs Planning, Papio-Missouri River NRD, Council Bluffs Public Works, Council Bluffs Water Works, National Park Service, Omaha By Design, Iowa West Foundation, and Sasaki Associates.

Inventory | AnalysisInterdisciplinary teams were organized to collect data grounded in four lenses. These lenses included Culture, Ecology, Land Use, and Mobility leading to analysis of influential systems. The collection of community assets and deficiencies through stakeholder engagement, government agencies, site observation, businesses, and research led students to understand the existing community.

The systems analysis resulted in a detailed examination of the elements or structure of the community as a basis for interpretation and discussion with stakeholders and fellow colleagues.

Throughout this process, I led the Ecology team in the development of an ecological systems analysis. This analysis developed into an understanding of vegetation degradation repercussions from the 2011 flood, discontinuity in open space networks, as well as, soil suitability analysis of buildablity and vegetation systems. The Framework Plan was informed by this analysis through appropriate future development patterns, important linkages in open space networks, and influential areas of habitat restoration to name a few.

Goals, Objectives, and Framework PlanInput from community members and an expert panel helped students develop a consensus of goals and objectives that guided the creation of the framework plan. A framework plan is a tool used to create a comprehensive vision of future development. It outlines specific long range changes to an existing or new development and suggests how to accomplish these tasks.

Design ProjectsPriority design projects were drawn and rendered to show conceptual images of projects which would fulfill the objectives of the green infrastructure framework plan.

“The inputs for a Green Infrastructure system in Council Bluffs will be founded on the existing natural and ecological conditions in the project area. An inventory of topics such as climate, hydrology, landforms, land use, vegetation, and habitats will identify a framework for the living and non living elements of the environment which should be protected, restored, and integrated into a Green Infrastructure Plan.” This defining statement guided the systems based approach used to understand Council Bluffs’ ecological networks.

Throughout this process of inventory and exploration, relationships between flooding and ecology emerged. The impacts of the 2011 flood highly damaged both the natural and built infrastructure, (trees and vegetated areas, parks, wildlife habitat, agriculture land, buildings, roads, other public infrastructure.) Through this study, it became important to understand how systems in place, both natural and built infrastructure, can proliferate, or mitigate damaging flood event outcomes.

An analysis of Council Bluffs’ open space network resulted in much discontinuity due to past infrastructure and development strategies. Conventional development over the last century focused on the protection of individual open spaces and natural/cultural resources. It is now understood ecological processes function more effectively when open spaces are connected. Using green infrastructure as a framework for development allows communities to protect important individual open spaces, as well as plan for an interconnected system.

The Bob Kerrey Pedestrian Bridge, a 3,000 foot long cable stay bridge allows pedestrians to cross the Missouri River between downtown Omaha, Nebraska and Council Bluffs, Iowa. The bridge is currently the only pedestrian access over the Missouri River, linking over 150 miles of trails between the two states. Over 8,000 people use this bridge every year, entering Council Bluffs, Iowa above a degraded floodplain and storm water outlet channel (769 Acre Sub-basin). This 157 acre inactivated aversion is juxtaposed to the newly complete Tom Hanafan River’s Edge Park (2012), a highly formal “Great Lawn” framing Omaha, Nebraska’s skyline.

This project aims to activate 157 acres of degraded riparian woodland at the nexus of downtown Omaha and Council Bluffs known as the chute, by developing a series of safe, flood resilient spaces, recreation, and education opportunities while accommodating habitat with native vegetation. The design strategy transitions the framed highly formal “Great Lawn” into a native floodplain forest. A series of native vegetation bands, inspired by the formal edge of the “Great Lawn” create a field condition transitioning between the two landscape typologies. The channel, situated in a newly defined band, becomes a storm water treatment channel, cleaning stormwater runoff before reaching the Missouri River. Multiple secondary paths meander perpendicular to the bands creating an experiential and educational landscape. The new space is both visually and experientially interesting from above as pedestrians enter on the pedestrian bridge and at grade as users cross bands of native vegetation.

Goals- Restore resiliency to the Missouri River floodplain and adjoining storm water inputs through green infrastructure implementation.- Repair Habitat by establishing a series of ecologically balanced zones informed by existing landform and vegetation, transitioning comfortably between thresholds.- Define space through developed zones containing programmable spaces and reinforcing habitat, while providing recreational and educational opportunities for the community.

Experiential Entrance from Bob Kerrey Pedestrian BridgeThe Bob Kerrey Pedestrian Bridge, the only pedestrian crossing of the Missouri River, serves as the entrance to Council Bluffs, Iowa Tom Hanafan River’s Edge Park. An experiential entrance is created as the user passes through the floodplain tree canopy into a clearing of vegetation bands creating another experiential field condition. Each band is planted with differing floodplain vegetation transforming the landscape into an educational, experiential amenity as users move above and across the bands. Use of appropriate floodplain vegetation and durable materials increases resiliency.

The stormwater outlet channel undergoes a transformation resulting in a system of weirs and vegetation strategies, This system cleans stormwater runoff from a community sub-basin by slowing conveyance, allowing for sedimentation, and utilizing physical and biological filtration. The channel naturalizes as it reaches the Missouri River to accommodate flood resiliency. The channel becomes another amenity to the experiential, educational, resilient floodplain landscape.

A Community Planning ProcessCrete, NebraskaWorked in Collaboration with: Dennis Krymusa (M.Arch) and Sarah Hansel (M.CRPL)

In fall 2012, during my 4th year, I participated in a two phase vertical, interdisciplinary service-learning studio partnered with Crete, Nebraska. Phase one’s objective as a studio was to create a master plan outlining goals, objectives, and detailed projects. Through an extensive inventory and analysis done by four teams: “History and People”, Environment”, “Infrastructure”, and “Land Use”, our studio worked with community officials and members to execute the master plan.

I was a member of the Environmental team along with two other colleagues. Along with understanding the environment Crete, Nebraska is situated in, we also developed a strategy to categorize the quality of the environment. Through researching climate, soils, land cover, eco-regions and the Big Blue River ecology and floodplain at multiple scales (State, County, and Community) we were able to identify important land cover and ecological patterns important in identifying appropriate areas of community expansion and environmental conservation, preservation, and restoration. Community parks were also studied by the environmental team and through an extensive analysis, the need of a park network system was identified.

Phase two transitioned into the development of project design solutions identified in phase one’s master plan. I investigated the development of Tuxedo Park identifying appropriate program to design environmentally intelligent solutions.

Tuxedo Park History

Tuxedo Park Fair GroundsCrete, NebraskaIndividual Design Project

Historic Tuxedo Park

In phase two, a continued collaboration with the community of Crete and members of Saline County to develop a design solution organizing program, identifying vehicular and pedestrian circulation hierarchy, and exploring appropriate areas of environmental restoration, conservation, and preservation. Through analysis of historic Tuxedo Park, we learned of the historic environmentally conscious design of the park. As a county fair grounds and a community park the to goal rearrange park program locating program of the county fair in an organized connected layout was established.

The floodplain of the Big Blue River impacted the design of Tuxedo Park as strategies of native vegetation restoration strategies were proposed for the hydrologic system through Tuxedo Park. To program the floodplain, the designing of a pedestrian walking trail connecting the Big Blue River to the county fair building program found importance. Reducing the vehicular circulation throughout Tuxedo Park was also an objective in creating a pedestrian oriented ecological park. Vehicular circulation becomes minimized with major event parking externalized from Tuxedo Park. With the reduced structural stability of the south vehicular bridge entrance to Tuxedo Park, redesignating the south entrance bridge as a pedestrian entrance allowed the bridge to stay while simultaneously reducing vehicular circulation through Tuxedo Park.

This Photoshop rendered perspective displays the drainage swale design solution. Understanding native vegetation strategies drove the restoration landscape through native grasses and wildflowers amending ecological degradation, soil erosion, and increased maintenance costs to the drainage swale system. The relocated walking bridge provides pedestrians with fairgrounds access avoiding vehicular circulation routes. Pedestrian trails interconnect a larger Tuxedo Park trail network to the Big Blue River though multiple routes, experiences, and distances.

At the current rate of structural breakdown, vehicular traffic will not be allowed to access Tuxedo Park from the south in the next five years. The design solution externalizes large event parking re-purposing this vehicular bridge into a pedestrian entrance. Parking is located to the south (bottom of image) allowing this bridge to escape abandonment. All vehicular traffic is routed to the northwest park entrance allowing south and east areas of Tuxedo Park to be parkland of changing

Environmental Integration Agriculturally Productive CampusWorked in Collaboration with: Joey Laughlin (Arch) and Sean O’brien (Arch)

In spring 2012, during my 3rd year, I participated in an interdisciplinary Landscape Architecture/Architecture studio grouped in teams of three. Our challenge was to site program blurring the threshold between architecture and landscape architecture elements. As a sustainable school design strategy, our design concept, to facilitate the intersection of two general field conditions (Agricultural/Ecological and Buildings), as a cohesive and educational environment lead us to the placement our site at an existing edge of two systems.

As a landscape strategy, the design embraces the hydrologic component of the site through a rainwater retention garden courtyard integrated within an edible agricultural landscape. The school structure mediates the educational threshold shifting between agricultural and ecological education systems.

The integration of sustainable parking was an additional design challenge of this interdisciplinary studio. Our strategy aligns parking program with the layout of our agriculture and building site orientation integrating it into to ecological forest system on site.

Page 36: Nathaniel M. Krohn | Undergraduate L.Arch Portfolio of Design (2014)

In fall 2011, during my 3rd year, I participated in a landscape architecture studio focused on site design with an emphasis on grading. The project site was located at Doane College in Crete, Nebraska, a community twenty miles southwest of Lincoln, Nebraska. Understanding the hydrologic, vegetation, and program systems of Doane College allowed me to make informed site decisions and be critical of existing circulation paths. Analyzing Doane’s vegetation system as a English Cottage style landscape informed my design decisions for both site design projects.

The Library Site at Doane College challenged our studio to take the large scale understanding of Doane’s vegetation, circulation, and program systems and refine them to a site scale. A general program requirement of locating two outdoor classrooms within the site was our design challenge. A further investigation of building program and landscape program assisted in the generation of additional program and site circulation. Understanding the vegetation strategy of Doane’s Campus, the fluctuation between a natural and maintained landscape, lead to the conclusion of a maintained landscape design strategy.

The design locates a small outdoor classroom/plaza at the face of the south library facade overlooking a tiered large outdoor classroom amphitheater. Circulation connects circulation from across Doane Lake to the existing circulation paths east and west of Doane Library. ADA circulation grading was a design challenge influencing design strategies. The final design strategy was to complete the recreational path around Doane Lake creating a closed recreational exercise loop.

This studio then lead into a construction documents adjunct course designed to take one of my studio design projects and complete a twenty page construction document set. The construction documentation course assisted me in site design refinement and allowed me the opportunity to further investigate the design details of my studio design project.

HDR, 2013 Summer InternshipUniversity of Nebraska - Omaha Hockey Arena; Omaha, NebraskaMy summer internship experience at HDR during the summer of 2013, reinforced many learning outcomes mastered during my education at the University of Nebraska - Lincoln. During this experience, I was able to work on many different projects in different phases of design. Conceptual design, schematic design, detailed design, and construction documentation were all project phases I was able to participate in as well as rendering presentation graphics. By working on multiple projects in different phases, I gained skills prioritization skills allowing me to prioritize tasks, moving between project scale, type, and phase, as well as meet deadlines with multiple projects types. Through this process, I gained much experience in understanding goals of project phases, learning the most in construction documentation. A clear understanding of correct content in each construction drawing fulfilled a learning outcome I set for my internship experience.

In the University of Nebraska - Omaha Hockey Arena project featured on the right, I assisted the HDR landscape architecture team in completing the schematic design package. A general understanding of design layout, material selection, and vegetation size, type, and count was the goal of this phase. AutoCAD drafting in all sheets related to the site became my primary task in this project.

Kapiolani Medical Center is located in Honolulu, Hawaii. To complete my internship experience at HDR, I was tasked to develop the planting strategy for the therapeutic garden. In addition to developing the planting plan for the site, it was confided in me to grade the site and prepared the layout plan, irrigation plan, grading plan, and details plan for the construction document deadline. Much research was used to develop the planting strategy as it used only native plant material to Hawaii. The planting plan was then submitted to a horticulturist from Honolulu for species

Ecuador, 2012 Study AbroadInternational Service-Learning Design Experience

Page 52: Nathaniel M. Krohn | Undergraduate L.Arch Portfolio of Design (2014)

In the summer 2012, following my third year, I participated in an interdisciplinary, vertical study abroad experience to the Galapagos Islands, Ecuador. This international educational experience gave me the opportunity to learn sustainable community-based development, cultural implications of working within communities, and extensive project planning, management, and evaluation. Partnering with the community of Puerto Ayora, we were able to work with three colleagues and an architect of Ecuador to plan, design, conduct, and evaluate short- and long-term goals and objectives for the Puerta Ayora public school.

My experience studying abroad in Ecuador was life changing. Mediating the discussion of design strategies for the Charles Binford street corridor adjacent to the public school was an educational experience. Embracing cultural dynamics of language barriers, work ethics, and living standards was an experience and education I was only able to gain by working with the community members of Puerto Ayora.

During my time in Puerto Ayora, I worked with my fellow colleagues for ten days developing a design solution integrating the adjacent food vendors into the school systems education system. In our design strategy, the food venders were allowed to stay in their location on municipal property with the sidewalk extending behind and between the venders to the school boundary. This design would allow for the continuation of the night culture of the street shown in the top image on the left while allowing for circulation to function on the site. The integration of a study program between the school and the food vendors, and new hotel design on the corner of Charles Binford and Av Baltra provides students with the opportunity to learn in realistic environments.

Ecuador, 2013 Study AbroadInternational Service-Learning Design Experience

Page 58: Nathaniel M. Krohn | Undergraduate L.Arch Portfolio of Design (2014)

During the summer of 2013, upon completing my fourth year in Landscape Architecture, I was able to return to Puerto Ayora, Galapagos Islands, Ecuador and participate in an interdisciplinary, vertical studio study abroad experience. This international educational opportunity allowed me to continue learning sustainable community-based development, cultural implications of working within communities, and project planning management, and evaluation learning outcomes.

Partnering with the neighborhood of Alborada, I participated in the development of the “Discover Alborada Park” Plan with intent to show a variety of possible design enhancements to the Park that will better serve the youth, adults, and community groups in the neighborhood.

Through principle based inventory analysis a series of studies informed realigning park program with a park zone strategy. This strategy sought to unify the park accommodating multiple uses for all demographics within the community.

Embracing cultural dynamics of language barriers, work ethics, living standards, and expectations of space was an experience and education I was only able to gain by working with the neighborhood members of Alborada.

5Form partnerships with the municipality for funding and support. Identify local arts groups who will take ownership of the spaces and who can move the Alborada Park Arts Program forward.

421 5Invest in alternative lighting over the courts. Reconfigure the size and position to be more aligned with the sun.

3 Remove debris and overgrown vegetation from the park. Relocate the play equipment to the new playground areas.

Emphasize the west and east entrances with banners, street paint, and vegetation.

Commission a local artist or hold a design competition for the south entrance to coincide with the construction of the new road.
