Abstract
Abstract The purpose of this research is to determine the best method to redevelop the public realm of the Central Addition to meet the changing desires and needs of the people of Boise. The Central Addition has recently been renamed the Boise LIV District to exemplify the city of Boise’s goal of creating a lasting, innovative, and vibrant community. To accomplish the city’s goal, along with several other stakeholders, relevant literature, case studies, and precedent studies were used to establish a strong understanding of successful public realm design. The main theoretical principles that guided this work were pedestrian-oriented design, the human perception of the urban environment, efficient design, historic preservation, and adaptive design. The selected literature discussed the importance of creating a comfortable, safe, and inviting downtown environment that meets the broadest range of human needs. The Boise LIV District public realm design uses an innovative design approach that looks beyond the landscape and presents a redevelopment plan that considers building use and layout, street layout, and the implementation of the design over the next 45 years. The American Society of Landscape Architects Code of Professional Ethics states that the discipline is dedicated to the “public health, safety, and welfare and recognition and protection of the land and its resources.” This project will demonstrate the role of landscape architecture in preserving and enhancing the resources of the Central Addition. The following design for the Boise LIV District public realm implements all of the stakeholders goals using an adaptive, efficient, and pedestrianoriented design approach. The design includes a mixed-use development with a major pedestrian corridor along Broad Street. The project would be built in three phases over the next 45 years. The Boise LIV District would include 856 new residential units, 1,260,329 square feet of commercial space, 468,074 square feet of office space, 280 hotel rooms, and 4,993 parking spaces. A pedestrian-oriented public realm with an array of green spaces and plazas will ensure a resilient and adaptive district that will meet the needs of Boiseans over time.

They subdivided part of the land to create the Davis Addition, which is where several homes west of 5th Street still stand today. Unlike the North End, the lots were much larger and reached full occupancy in 1912. The railroad, which originally skipped Boise, came in 1894 with a depot located along Front Street.

Since developers and construction corporations have focused on the economic viability of urban projects, many would suggest that they have inadvertently overlooked basic human values and experience. There are many theories for how a city should develop and function, but several authors including William Whyte, Jane Jacobs, and Kevin Lynch believe that the value of a city is truly found in the streets. The experience of the Central Addition’s public realm is the main focus of this project. The city of Boise recommended that this project focus on place-making, that is, creating spaces that promote community interaction, have common distinct attributes, a shared theme, and expresses the value of the neighborhood.

The scale of the street frontage is key in creating a successful district.
At the edge of a district, large park, or single use structure, there are usually set boundaries that create a perceived barrier. One solution is to blend the two uses together in a mixed-use transitional zone by pushing and pulling the building or park across existing boundaries. Effective tactics for city development include providing visual order while maintain a diversity of building uses. There must be a clear separation between public and private spaces and buildings must be oriented towards the street.
Sidewalks need to have people on them and they need to be on them
fairly often. Sidewalks and streets must also meet the needs and grab the attention of the city’s visitors. Stores, bars, and restaurants are very useful at getting people on the street. The more people, the safer the neighborhood, the more strangers are welcome. By providing commerce, a general liveliness, use and interest, community development and self-governance of a neighborhood street will be promoted.
Applying this to the Central Addition means that streets and
sidewalks need to be safe, promote community interaction, have a variety of building types and ages, have visual order, but a diversity of buildings and uses, effective public transportation, street frontage that is designed for the human scale, and promote community ownership to create a successful neighborhood, district, and city.
The Social Life of Small Urban Spaces, by William Whyte, is a
manual based on research conducted by the Street Life Project in 1971. In the book, Whyte talks about his observations of how people perceive and interactive with their urban environment in 16 plazas, three small parks, and other small spaces in New York City. Whyte uses specific observations to

Some of the observations that Whyte made include analyzing the
type of people using urban spaces. He noticed that tenants and/or workers of nearby buildings, not adjacent buildings, use plazas that were under study in New York. The most popular plazas are very social spaces with a high number of couples and groups. According to Whyte, the more women in a plaza, the better, because it demonstrates that the plaza is safe and comfortable. The typical daily schedule for an urban space has sporadic activity throughout the morning with construction workers taking an early lunch at 11am, followed by everyone else between 12-1pm. The number of people tapers off around 6:30pm when most activity ends for the day.

Whyte observed that people tend to sit where there are places to
sit, no matter the conditions. Socially comfortable seating is key, that is, a variety of seating types and arrangements. Seating does not necessarily have to be a bench; it can be a ledge or step. People will sit on a variety of seating heights, no matter how short or how tall they are, but the depth of the seating matters. If access is provided on both sides of a seating area, it is important to make the seating deep enough to provide enough space for two people comfortably. According to Whyte, “While 30 inches will do it, 36” is better” (1980, 31). Benches are a type of seating that are not designed well or used well. The dimensions are typically 7.5 feet long by 19 inches deep, which is too small and, if stabilized with concrete, reduces flexibility, resulting in less

Many buildings in Boise, such as the structures that made up Chinatown, were destroyed in the last decade to make way for new buildings with no historical relevance at all.

CCDC and Preservation Idaho have recommended a variety of
methods to preserve the history of the Central Addition, but which method works best for the district? The original plat of Boise consisted of a grid network of streets with lot sizes that were much larger than many city lots of the time. Boise was laid out east to west to follow the topography of the Boise River shoreline. This was completed when the main form of transportation was the cart and buggy. The city’s urban form has kept fairly close to the original plat of the town. As a result, the Central Addition has a very static urban fabric that was eventually influenced by the railroad. A train depot located next to the intersection of Capitol Boulevard and Front Street changed the circulation and building type within the District. According to Scheer, the “original pattern of an urban tissue has a very long-lasting

The Adaptive Public Realm - Boise LIV District Public Realm Design different economic and cultural backgrounds� (2013, 18). The Central Addition has the potential to be very culturally diverse. The district is located just south of an affordable housing complex along Front Street and north of the Boise State University Campus, which is planning on expanding their campus and is in need of more residential units for students. A developer already has plans to construct a new $24 million apartment complex with parking and commercial space on the west side of 5th Street beginning October 2015. A well-designed public realm in the Central Addition will meet the needs of all users, no matter their culture, age, or income. Boise’s Downtown Walkability Analysis, which references case studies and references from the book Walkable City: How Downtown Can Save America, One Step at a Time, argues that Boise could be more walkable. The report concludes that Boise should have a network of small, interconnected blocks to make walking more convenient. Streets should be pedestrian-oriented and narrower to promote a safe, walkable downtown experience. The environment is also an important part of the downtown experience.
An ecologically respectful community preserves natural systems that
benefit their health, the community, and, of course, their environment. In Design for Ecological Democracy, Randy Hester explains the importance of reconnecting lost relationships with each other and our environment. Suburban developments separate people from their community, destroy the natural habitat, and fail to provide an enjoyable experience that we can call home. Democracy is the hallmark of U.S. culture, but since WWII, trends in zoning and development have seen a pattern of residential development that restrict our ability to choose where and how we live. Typically, a specific income level is targeted for a development and the tenants are provided with a specific type of lifestyle that they must fit into. Current theories of
i 16
Downtown Green Spaces planning are trying to reverse those patterns and encourage diversity of both the use and typologies. Hester believes that urban design must enable people to be in communities rather than zoning-segregated enclaves. A community should be an informed democracy with the opportunity to voice a thought or opinion. Cities that are ecologically resilient enhance community and provide a pleasurable living experience.
Hester’s new design principles are founded on three fundamental
ideas that integrate democracy and ecology: enabling form, resilient form, and impelling form. A simple bench, community gathering space, or park enables the community to interact. A well-preserved or reintroduced native habitat adds an ecological resilience that will support the community throughout generations. Urban landscapes provide spaces for stormwater infiltration, urban agriculture, native wildlife that is appropriate for urban environments, and fresh air. The architectural style and complimentary

Project Relevance
The city of Boise desires the Central Addition to be lasting,
innovative, and vibrant. The focus on creating a LIV District is to create a mixed-use development that serves the needs of the people and develops a robust, 24-hour, downtown presence. The city of Liverpool, England had that exact goal when they set out to redevelop their downtown. Liverpool One was a massive investment that was successful in creating a vibrant downtown experience. The success of the project is attributed to many things including a diversity of uses and architectural styles, a permeable urban fabric with a

of the U.K. economy with the help of its location on the River Mersey and the Irish Sea. As a large trading port, the city thrived until recently when the city fell into a depression. A recent economic and cultural revival has taken place, which has boosted the city’s economy and growth. Liverpool One is an example of a recent investment that has helped transform the city. Liverpool One is a mixed-use, revitalization project that is located close to the shoreline of this famous trading city. Multiple architects and landscape designers under BDP, an international, interdisciplinary firm based in the United Kingdom, designed the £1 billion project.

The Adaptive Public Realm - Boise LIV District Public Realm Design city has a major port on this river, which connects Liverpool to the region and the world, making Liverpool a major world trading city. Birkenhead and Liverpool are connected by A59 trunk road, which is a highway that connects two major cities. The A59 is located just three-quarters of a mile to the North of Liverpool and, along with other major highways like A580, A5039, and A57, provides great circulation and connections to the rest of downtown Liverpool. Liverpool One is located within a half-mile of the Liverpool Lime Street Station, the city’s main train station, and one block up from several major docks and ferry terminals, enabling this site to have great circulation and connectivity. Multiple historic buildings as well as one of the oldest dry docks in human history surround the site. Designers had to create a contemporary development that not only connected regional and local Simple, Modern Materials transportation links, but also communicated the culture and history of the city at the pedestrian level. Genesis of project
When Liverpool was named the 2008 European Capital of Culture,
the city received 800£ million of economic benefit. This helped spur the regeneration of downtown Liverpool starting with Liverpool One, the largest city center regeneration project in Europe. It was projects like this one that would bring Liverpool out of an era of economic decline and underinvestment. The project took four year to construct and is considered by many to be the most important development in Liverpool in the last 60 years. In the 1980’s and 90’s, Liverpool went through a period of economic downturn that resulted in investors and major businesses leaving the city. It ranked thirteenth in the league of national retail destinations. The city was Liverpool One Nightlife

Special occasion shoppers are those who are not in a rush and shop based on choice, social shoppers consider shopping to be a pastime, and mission shoppers are in a rush and shop frequently at their favorite locations. To meet the needs of a variety of retailers and customer types, Liverpool One was designed as an open scheme shopping center that included five discrete zones, each with its own retail theme and unique character.

During the design process, and within a year of opening their doors,
interviews with retailers and consumers were set in motion. Most retailers were aware of the Liverpool One project, but were not convinced of its potential success since a detailed scheme had yet to be revealed. To solve these issues, an advertising campaign targeted the media, key retailers, and agents to understand the details and sell the project. Another important part of the Liverpool One research was a consumer analysis. In 2007, sixteen focus group meetings were conducted to collect data of the reason why people shopped at certain locations.

and the Pearl District. Boise also has several districts including 30th Street, Westside, Central, and River Myrtle – Old Boise districts. Boise’s City goals align almost perfectly with the goals Portland had for the Pearl District. The city desires a high-density urban neighborhood with great connectivity, open spaces, a mix of uses, and a clear connection to its history. The Pearl District will be used as the main case study for this project. During a field trip to the Pearl District, an analysis of landmarks, nodes, paths, and edges was completed to understand why the district is successful. The streetscape, building’s architectural style and uses, layout, and the vehicular and pedestrian network, were heavily scrutinized to understand the framework that is necessary to provide a similar product in Boise’s Central Addition.

The Pearl District has an excellent network of streets and pedestrian connections. Every block has north-south and eastwest connections and Portland’s Streetcar, which runs along NW 10th and NW 11th Ave, improves connectivity even more. Site Analysis
The Pearl District has different districts with unique themes. 13th
Street from Northwest Davis to Johnson Street is on the National Registrar
of Historic Places for having historic architecture and streets. The street even has the original loading docks and alleys. What was once loading docks are now sitting and eating areas that sprawl out of restaurants and shops. Three well-designed parks anchor the center and northern end of the Pearl District. The newest developments, which are mixed–use with tall residential towers, line the northern blocks. Construction is still booming in this area, filling in any leftover vacant land. Aside from 13th Street, the streetscape is very similar throughout the Pearl District. Typical streetscape includes one vehicle land in each direction, eight feet of on-street parking, and a bike lane, which varies in size and is sometimes integrated into the vehicle lane. The majority of sidewalks in the Pearl District have a four-foot buffer between the street and sidewalk. This area consists of pavers and street trees that are offset by 20-30 feet. Trees are typically 30 feet tall and are pruned to promote visibility at eye level. Portland’s streets are very simple, with street signs

Once a district of dilapidated warehouses, the Pearl District has
become one of the most renowned places to live in Portland, Oregon. It is a vibrant community with a great mix of uses and architectural styles, plenty of community spaces, and great connectivity. It has become an urban icon of urban living that is a great case study for urban renewal districts. Also known as “The Pearl” of Portland, this district was originally platted as part of Couch’s Addition in 1869 as a north-south, east-west grid. In 1896, the Union Station, which still stands today, was built. In 1905, the Lewis and Clark Exposition boosted Portland’s population and expansion near the north end of the district. A new rail line was built, which connected Portland to Seattle and Spokane. The rail system expanded during the early

The Pearl District played a key role in Portland’s housing strategy and growth management goals. The highdensity urban neighborhood has helped relieve pressure on the expansion of the Urban Growth Boundary, which protects rural resource lands. Design, Development, and Decision Making Processes
In the early 1900’s, the Pearl District became known for furniture
manufacturing. Major manufacturing and brewing companies like Henry Weinhard, Sherman Clay and Co, Blumauer-Frank Drug Company, and other companies kept the area busy until the 1950’s when transportation patterns changed from water and rail to roads and highways. In 1990, the
The 1980’s also saw the creation of the River District Urban Renewal Plan, which provided tax increment funding for improvements within the district. The vision the Pearl District was expressed in the creation of the Pearl District Development Plan, a planning document with very specific goals and guidelines for the development of the district.
Today, the rail yard has been repurposed into the US Postal Office
processing plant along NW 9th Ave and many warehouses have either been torn down and replaced by mixed-use developments with large residential towers, or repurposed into centers for retail and restaurants. Warehouses were removed to make way for Jamison Park, Tanner Springs Park, and the Fields Neighborhood Park. Although most of the Pearl District has very modern architecture and new urbanism ideals, historic architecture and sidewalks are well preserved along 14th Street.

The Portland Streetcar has aided the use of public transportation and the reduction of personal vehicle use. According to the Portland Streetcar Development Oriented Transit Plan, the city of Portland has invested $3.5 billion into the two blocks that the Streetcar runs down, which in turn influenced the construction of 10,212 new housing units and 5.4 million square feet of office, institutional, retail and hotel. There is high transit use and very low reliance on automobiles. Pearl District residents, employers and visitors “travel half as much by car as the regional average” (Pearl District Access and Circulation Plan - Existing Conditions Report).

are approximately 110 blocks that make up the district. Thirty blocks (27%) are predominately residential, eight (7%) are open space, seven (6%) are retail, three (3%) are parking, and six (6%) are under construction. The other 56 blocks (51%) are almost equally mixed-use and have no predominant building use. User/use analysis
To get a taste of urban living in the Pearl District, a website called
Yelp, which uses crowd-sourced reviews of local business, was used. The common opinion of the Pearl District, according to residents, is that there is an excellent variety of residential, retail, and commercial spaces. The district is very walkable, there is great access to grocery stores, retail, and public transportation. Access for elderly or disabled people that use wheelchairs is still convenient. Parking on the other hand can be very tough for residents, but each residential tower has underground parking. Powell’s bookstore is a popular landmark for locals and for visitors and, according to the receptionist at the front desk, it is the largest used bookstore in the world.

Skyscrapers now dominate the landscape and their wealthy inhabitants dominate the streets. In the Downtown District of Portland, one can experience a spectrum of people on the streets. The people represent a variety of ethnic groups, ages, and incomes. The Pearl District on the other hand, has a very clear designation for their tenants and users. It is designed for high-end users, with little to no homeless in sight. The homeless, and potentially the original residents of the Pearl District, take refuge under the I-405 overpass.
Although getting around within the Pearl District is convenient,
there are several main barriers that limit circulation outside the district. Burnside Street is a major arterial that can be frustrating to cross when traveling downtown. Interstate 405 to the west creates a barrier even though

They are low-cost, easy to install, make the street more lively, and improve the aesthetics of the street. Curb bulbs, or curb extensions are a strategy that pushes the sidewalk out into the street at key locations. The extension can be used to calm traffic, shorten pedestrian crossings, and provide a space for public amenities like bike storage, stormwater infiltration gardens, and seating areas.

Seattle, Washington is at the heart of the evergreen state and hence,
a very green city. Located on the Puget Sound with steep topography, this beautiful city has many challenges, but also great potential to improve its streets. Gehl Architects set out to uncover specific examples of how Seattle could be more livable. Since both Boise and Seattle are challenged with creating a livable downtown, the lessons learned from this precedent study
Seattle’s Sidewalks will be useful in enhancing Boise’ public realm.
A successful public realm has a balance between road users, a strong
pedestrian network, multifunctional public spaces, a diversity of people, a variety of different places, and an increase in the amount of time people spend in the public realm. Seattle struggles with a disconnected waterfront, an office focused downtown, minimal open space, a fragile urban culture, and an unbalanced traffic system. To mitigate those problems, the city has developed and strengthened their public realm by investing in their public transportation, promoting densification and downtown living, implementing public amenities, and investing in a new park – the Olympic Sculpture Park. A clearly defined network of roads and walkways ensures great connectivity, mobility, a simple hierarchy of streets, safety, and creates a more enjoyable experience.

The city of Regina is located in Saskatchewan, Canada and has a
population that is similar to Boise. The city emerges as an oasis of trees, people, and builds among the flat, central plains of Canada. According to “Discover Regina’s History,” the area used to be buffalo hunting grounds for the people of the First Nation, or as Americans call them, Native Americans. It originally received the name Pile of Bones for the stacks of buffalo bones leftover. White explorers, fur trappers, and surveyors settled the town in the 1880’s and the name was changed to Regina, which is Latin for “queen”, in honor of the reigning English monarch, Queen Victoria.
Today, the city is a thriving metropolis with a vibrant culture and
a variety of memorable landmarks, great streetscapes, and parks. The city established eight major goals to achieve a more livable city. The city
Regina Downtown Elements desires to create a downtown that is defined and framed by residential neighborhoods, organize the city around a central park, plan for a welldefined urban forest, cultivate and support cycling as a viable means to move about downtown, invest in an exceptional public transit system, encourage friendly building facades, and create places for gathering to allow arts and culture to flourish (Regina Downtown Neighborhood Plan - Walk to Work).

Water from the street, sidewalks and building, is directed via curb cuts into twenty-seven infiltration basins and four rain gardens, which naturally filter the water before it is piped into eight underground cisterns. The water is reused to drip irrigate the entire site. The City Hall was emphasized using a raised plaza, which was constructed using 4x18� pavers that extend across the street to the future memorial park and Big Well Museum. The plaza not only provides great connectivity and a similar material scheme through the town, but also slows vehicular movement.

The Adaptive Public Realm - Boise LIV District Public Realm Design
Design Process
The design process for the Boise LIV District public realm took on a linear path in order to analyze all of the opportunities
and constraints as well as the goals of the stakeholders without ignoring any details. The main conclusions from the literature review and case studies stressed the importance of place-making and providing a friendly, pedestrian-oriented public realm. The final design must be aesthetically pleasing, functional, and create a unique sense of place that will invite people into the District. In order to accomplish this goal, the design process will include a thorough inventory of the site’s strengths and weaknesses. The goals established by the City of Boise and the U.S. Green Building Council compared with the analysis of the site inventory will produce a program, or a list of specific design elements, that are desired for the final design. Programming requires very specific sizing and performance standards that are based off of the literature reviews, case studies, and Boise’s Downtown Design Standards. The program will be illustrated in three concept designs that will attempt to achieve the goal of creating an adaptive, efficient, and pedestrian-oriented public realm using different layouts and styles. The three concepts will be compared to see how effective they are at achieving the goals and program. A final master plan will be created from the modified, selected concept design. Important details will be illustrated in four focus areas which will also have sections and perspectives. Supporting details

According to the Boise Architecture Project, a student-led project
Name: Beck House Architecture Style: Queen Anne Cottage Private Building
focused on architectural history and preservation in the Treasure Valley, there are currently ten historic structures in the Central Addition. They are the last remaining houses of the Central Addition when it was first developed in 1863. Within the last two years, two homes were burnt down, three homes along 5th Street were put up for sale, purchased, and then demolished to make way for a six story commercial building. There have been efforts to preserve and relocated some of the remaining homes. The following is a description of the remaining homes.

These homes, located along 4th, 5th, and Broad Street, are where
Boise’s elite used to live before the train depot was built along Front Street. The train brought low-income tenants into the area and the Central Addition fell into decline shortly after. According to the article “Still Hope for Historic Boise Homes in Central Addition,” the Wood and Fowler houses located along 5th Street have a high potential of being preserved and moved to a new location. Mike Brown, the co-founder of LocalConstruct, which is a private real estate investment and development company that was responsible for remodeling the famous Owyhee building in 2013, is considering dismantling the Beck house and reassembling it in Atlanta. There is interest in preserving the Jones house also, but the future of the houses are still unknown.
The Central Addition is planned to be a dense, mixed-use
development with a focus on downtown living. These structures no longer hold any functional value for the district and, as a result, only the materials of the homes will be preserved and re-purposed within the public realm.

CENTRAL ADDITION STREETSCAPE CHARACTER The images below show a vehicular-focused streetscape within the Central Addition. Narrow sidewalks, wide streets, and a lack of clear network of walkways make people feel unwelcome and uncomfortable while walking through the District. New developments like Trader Joe’s, as seen in the Front Street and Capitol Boulevard image, have widened the walkways and maintained a pedestrian-oriented scheme throughout the site. The Central Addition has street trees on every block, which adds to the aesthetics of the area and provides a habitat for local birds. The Boise LIV District public realm design will add to the vibrancy and livability of the area by establishing more residence, commercial space, and office space along with a welldefined network of pathways and streets.

As the District redevelops, these power lines will be moved underground to improve aesthetics and make more space for future development. The city of Boise has standard light posts, pavers and other sidewalk materials, which will be utilized in the design of the public realm. Additional amenities that are typically found on Boise’s streets include concrete planters, benches, and trash receptacles. Although the Boise LIV District is meant to have a unique character, some of the standard street amenities seen in the images below will be used in the design to ensure that the entire city has a similar theme throughout.

PEDESTRIAN CROSSINGS
According to the city of Boise’s
Downtown Walkability Analysis, the city is currently more walkable than the typical mid-sized American city center (2013, Speck 4). A more walkable city means a better urban environment for urban dwellers, better connectivity, and more people on streets, which equals more business, safer streets, and more fun streets. Downtown has an abundance of one-way streets. The oneway system has been proven in several cities including Savannah, Georgia and Vancouver, Washington to have a

negative affect on businesses and the number of people on the street (2013, Speck 22-23). Furthermore, the report states that Front and Myrtle have too

JUMP Base Map - Not to Scale Jack’s Urban Meeting Place, or JUMP, is a not-for-profit, interactive creative center and community gathering place. The building and surrounding park and plaza is planned to be completed by Fall 2016. JUMP will be a major landmark, social space, and pedestrian-friendly area in downtown Boise adding to the vibrancy and unique character downtown. A clear pedestrian connection between JUMP and the Boise LIV District will encourage walkability downtown. Since the JUMP center will be a major landmark at the western end of downtown, a landmark must be established at the eastern end that has a similar scale and impact on the area.

BOISE URBAN ENVIRONMENT OBSERVATIONS GROVE PLAZA The following observations of the Grove Plaza looked at common trends seen in and around the plaza. The majority of people walking through the site were couples and larger groups of people. The site attracted a lot of skate boarders and long boarders because of the large amount of open space. Most people walked through the plaza without stopping to sit or look around. They took a direct route without wandering through the plaza. There are two main walkways that intersect at the Grove Plaza that results in people walking through the plaza to get somewhere instead of stopping and exploring the plaza. Movable outdoor seating and tables might be a good method of inviting people into the site. People were curious about what was behind the construction fencing, which means that keeping certain landscape elements out of view might raise people’s curiosity and invite people in.

ANNE FRANK MEMORIAL The Anne Frank Memorial is located along the Boise River just south of the Boise Public Library. One of the most common trends in this area was the amount of people that were interested in reading the plaques and viewing sculptures around the site. There were multiple cyclists that rode through the site, which shows the importance of having clear pedestrian corridors to invite people into a space. The memorial has plenty of seating that is used by people during lunchtime. There are separate spaces that are split off of the main pathways, allowing people to stop and explore the site or pass through the site without stopping. The memorial also works as a transitional space allowing people to go through the space to get to their destination. The area is well lit with natural light, but does not have the best lighting at night. Better lighting during the nighttime would increase the level of safety and security. There was a couple that stopped to eat lunch and sat facing each
other in the sun. Ann Frank Memorial has a clear line of sight that provides great visibility and keeps the site safe during all times of the day. Retention walls and shrubs isolate the site from 9th Street and Capitol Boulevard, which are very busy, loud streets. The area is well maintained with very little litter, which means that people appreciate the space.

8TH AND IDAHO INTERSECTION PUBLIC SPACE The intersection of 8th Street and Idaho Street is a very active, social space during the weekday and it is even more popular on the weekends. Both streets have a variety of restaurants and retail space. A common meeting place is at the corner of intersections because of the large curb bulbs that extend out into the street and provide a large gathering space. Every corner of the intersection has a light post, garbage receptacle, a no parking sign, a street tree, and an entrance to a major restaurant. A unique paver material is used to separate the different spaces along sidewalk uses. The sidewalk consists of a two-foot buffer off the street, an eight-foot designated eating area, a five-foot section down the middle of the sidewalk designated for
walking, and a four-foot section for street trees and amenities. The amenities consist of street trees, which were Honey Locust along Idaho Street, a bus shelter designed in a way that does not interrupt the pedestrian flow, garbage receptacle, light posts, and street signs.

The Adaptive Public Realm - Boise LIV District Public Realm Design
Conceptual Design CONCEPT #1 Pros: • Street diet creates a pedestrianfocused streetscape throughout the entire Central Addition • Great pedestrian connectivity • The smaller building footprints in the Energy Zone’s commercial area evoke a more artsy, historic building style that works as a transition between BODO, the Basque Block, and the Historic Business District • Residential and retail mixed-use buildings south of Myrtle work well with the surrounding context - great connection to the park for residents and easily accessible retail • Great layout and spacing of public spaces Cons: • Park/plaza space next to Idaho Independent Bank and the UI Integrated Design Lab provides a public space for employees and students, but it’s along a busy, noisy road - Front Street • Needs more office use • Difficult pedestrian crossing at South Avenue A because there is no existing intersection • Potentially too many residential towers that will block views of the foothills

CONCEPT #2 Pros: • Large gateway park into downtown works as an excellent entrance and public space for residents and visitors • Park/plaza in the Energy Zone pulls people in by reaching across the pedestrian corridor and the street • The eastern end features a park with a water feature that relates to the Boise River and reflects views of the foothills • The building layout responds to the character and theme of each zone • The bridge across Myrtle provides great pedestrian and urban wildlife connectivity • Good spacing of public spaces along the pedestrian corridor Cons: • The bridge across Myrtle might bring unwanted wildlife into downtown • There is a potential for too much residential in the Residential Zone - mixed-use development is a better solution • The residential building next to the commercial Park Place building, south of Myrtle, might be too close. Provide more space or modify Park Place to connect better with residential buildings • Provide a better mix of uses

Centennial Plaza Perspective 1
Centennial Plaza is an inviting, multipurpose, and fun public space with a myriad of amenities. The pedestrian corridor runs directly through the plaza to bring people into the site. The space has plenty of seating, some of which is movable, an outdoor chess set that is open to the public, an interactive water feature that borders the plaza, and a shared street to increase the importance of the pedestrian. Trees like the Thornless Honeylocust (Gleditsia triacanthos inermis), Hornbeam (Carpinus caroliniana), or the Sawleaf Zelkova (Zelkova serrata) are the selected species for this space because they provide excellent dappled shade.

Civic Plaza Perspective 1
The Civic Plaza is at the intersection of two major pedestrian corridors. One runs along what is currently Broad Street and another that would run along South 2nd Street. The corridor connects the Ada County Courthouse to the Discovery Center. Because this space is located at a prominent crossroads in the Boise LIV District and is within the Neighborhood Core, the plaza contains amenities that are family-friendly and geared towards all ages. An interactive water feature and a natural rock play area, which are reminiscent of the Boise River and rocky foothills, allow children to interact with their environment in a fun and safe way. Large grass lawns and picnic tables provide spaces for families who want to relax and enjoy a meal. A multicolored spotlight, located at the center of the plaza, adds light and color to the space. Clear accessibility and visibility creates a safe and inviting atmosphere. A prominent water feature and reflecting pool adds a soothing sound for people enjoying a meal in the outdoor eating and seating areas bordering the Civic Plaza.

Albertson’s Plaza Perspective 1
Albertsons’s Plaza, named after the community grocery store, located within the Community Retail Zone, is geared towards the families and retailers located within the district. The multipurpose space features movable outdoor seating, a section for activities like Ping-Ping, a space for small community events, and a large area for the Farmer’s Market. Two grass lawns with shade trees soften up the hardscape surfaces. A pergola wraps around the space to provide shade and a separation of the outdoor eating spaces from the plaza where events will be held. A shared street takes the focus off of the automobile and brings emphasis to pedestrians. The buildings around Albertson’s Plaza will also contain retailers and community grocery stores.

Gateway Park Perspective 1
Gateway Park is the eastern terminus of the Boise LIV District as well as the gateway into downtown Boise for people crossing Broadway Bridge. The multipurpose park has a large grass lawn and a stage for a variety of events and concerts. Two bus stops located along South Broadway Avenue accommodate public transportations needs, reduce the dependence on the automobile, and decrease traffic levels during large events. A prominent sculpture inspired by Janet Echelman, a world-famous artist, stands at the end of the pedestrian corridor and is tall enough to be seen from the western end of the District. Two interactive reflection ponds reflect views of the Boise foothills, the sculpture, and allow people to cool off during hot summer days. Gateway Park acts as a major landmark for visitors as they enter downtown via Broadway Bridge.

The shade analysis ensures that buildings to the north have sufficient solar exposure, especially during winter months. This analysis was calculated at noon during the Summer Solstice, Equinox, and Winter Solstice. Sunlight during the Summer Solstice, seen below, radiates into every part of the Boise LIV District. Every plaza and space along the pedestrian corridor would receive sufficient sunlight during the day.

The solar radiation at noon during the Equinox would still be sufficient for buildings located to the north. The shade angles would be at 47 degrees, which would cast a 46- foot shadow for a four-story building. The buildings south of the pedestrian corridor are designed to let the maximum amount of sunlight into the corridor while maintaining a dense, tall development.

The solar radiation at noon during the Winter Solstice will reach the base of the buildings to the north, allowing sufficient sunlight into the bottom floor. There are several instances where the pedestrian corridor is more narrow and will only receive light into the second floor. To mitigate this problem, reflective building materials will be used along these sections of the pedestrian corridor to reflect light into the shaded areas.

Below is an example of a narrow section of the pedestrian corridor. Sunlight barely reaches the bottom floors of the northern buildings. To mitigate this problem, reflective building materials are used to allow sunlight to penetrate even the most shaded areas. Most buildings that are south of the pedestrian corridor are three stories tall, allowing the winter sunlight to penetrate the first floor completely.

The stormwater management plan provides a method of capturing and filtering stormwater runoff from impervious surfaces. The introduction of more buildings, walkways, and plazas add additional surface area for rainwater to accumulate and run off the site into a nearby body of water like the Boise River. This may cause flooding and erosion downstream. The 26,634 square feet of stormwater infiltration gardens collects the runoff, filters the pollutants, and infiltrates the water into the ground, recharging the aquifer below the surface.

BOISE LIV DISTRICT
Phasing is an important element of the Boise LIV District design. To ensure that this design meets the needs of the city of Boise while meeting the desires of developers and fits into the current state of the Central Addition, three build-out phases were established. In Phase One, dilapidated buildings will be demolished with an effort to preserve and reuse materials on site and will be redeveloped along with vacant lots. This phase will occur over the next ten years and will re-purpose a major section of Broad Street into the pedestrian corridor.

Phase Two will continue to redevelop buildings that are at the end of their life span. The life span of a grocery store or commercial building is typically around 40-50 years. The buildings south of Myrtle Street were developed in the early 90’s, so these buildings will be re-purposed or demolished and redevelopment by 2040. Properties that were recently built or have a longer life span due to recent redevelopment or remodel will be preserved. These buildings include WinCo, Whole Foods, Walgreens, CSHQA, Trader Joe’s, the University of Idaho Integrated Design Lab, Concordia University School of Law, Idaho Independent Bank, and Park Plaza.

The final phase will include a full redevelopment of the Central Addition. In 2060, Trader Joe’s, which was built in 2013, will be at the end of its life span and will be redeveloped. As the city transitions towards more mixeduse, dense developments, the Trader Joe’s block will not meet the needs of the people.

Conclusions
Axonometric
This project is set up with several major phases that help refine the goals, objectives and program
of the Boise LIV District. The research section of this project reveal that a well designed district consists of edges, landmarks, pathways, and nodes. A good network of paths and community space increase the
Tree Canopy
potential for human interaction and community development. Streets should be playful, inviting, and enjoyable for all age groups and income levels. An urban neighborhood should be dense, diverse, and designed to the human scale. Any public space should have plenty of seating and needs to be safe and
Green Roofs
secure. A walkable, pedestrian-oriented downtown adds to the vibrancy and livability of downtown. A district should have a mix of uses and a variety of housing types. Choosing literature from different time periods was an excellent way to compare and contrast human values over time. The focus of creating a pedestrian-oriented design was discussed in both older literature written by Lynch, Jacobs, and Whyte as
Vegetation
well as newer texts like the Urban Design Handbook.
All of the lessons learned from the research are supported by the case studies that confirm the
importance of planning for a mixture of residential, commercial, and office use. Providing an excellent
Bioswales & Water Features
network of pedestrian walkways, public spaces, and pedestrian-oriented streetscapes create an inviting, livable downtown atmosphere.
The goal of the Boise LIV District is to create an adaptive and lasting public realm, use an efficient
Buildings
and innovative design approach, and create a pedestrian-oriented public realm that meets the broadest range of needs while implementing the lessons learned from research, case studies, and precedent studies.
The final design for the Boise LIV District public realm establishes a strong mixed-use building
scheme with a clear network of pathways and vehicular circulation. The pedestrian corridor, that
Walkways
would replace what is now Broad Street, would enhance the livability and vibrancy of the District while providing a clear connection to Boise Downtown (BODO), the Basque District, and the Historic Business District. A large network of stormwater infiltration gardens would collect stormwater runoff from the impervious surfaces, putting less stress on the Boise River and downstream bodies of water. The gardens would add to the aesthetics and sustainability of the District. Gateway Park would act as an entrance to downtown as people cross over Broadway Bridge. It would also be the eastern terminus of the Boise LIV District. The introduction of green roofs in the District would provide a flexible space that would be used for urban agriculture or act as a private space for residents. The urban tree canopy would create a habitat for birds and provide shade for people on the streets and along the pedestrian corridor. This design achieved all the selected goals, objectives, and programming elements.
