April is World Landscape Architecture Month, an international celebration of landscape architecture. WLAM introduces the profession to the public by highlighting landscape architect-designed spaces around the world. Today we visit Seoul, Korea to highlight the transformation of Cheonggyecheon River from concrete waterway to a revitalized urban park.

I like to visit urban parks while on vacation. Visiting parks allow me the opportunities to people watch and observe how different cultures use and interact within public open spaces, especially in dense cities where open space is often rare, but easily accessible by public transit.

I recently visited Cheonggyecheon, a 3.6-mile-long stream corridor located in downtown Seoul, South Korea that attracts over 60,000 visitors daily. For years, the Cheonggyecheon stream was paved over with concrete with an elevated highway built above it. But recently, the government removed the roadway and transformed the once concrete channel into a public open space. The stream was restored with vegetation, walkways, stages, crossings, water play, and seating areas, creating a multifunctional and sustainable public space for the citizens of Seoul.

The Cheonggyecheon River is supplemented by potable water pumped from the Han River, but the benefits to the surrounding community, biodiversity, and quality of life is still apparent. Depending upon the access point, visitors can experience a slowly changing landscape – from an urban experience with concrete walls and edges to a more natural stream experience. The redesign kept remnants of the highway that once covered the stream. Art, historical photos, and monuments of cultural significance related to the stream were integrated in the design.

The park never closes. I’ve visited the park during the day, but also during the late evening and early morning. No matter the hour, I’ve always felt safe walking through Cheonggyecheon. The urban park is heavily populated at all hours with people leisurely walking, exercising, and commuting to their destination without having to worry about cars. While walking the Cheonggyecheon’s length I thought of our own Los Angeles River, an urban waterway slowly undergoing a similar transformation from an inaccessible concrete channel to a thriving open space. My only interaction growing up with the Los Angeles River was through the backseat car window driving across the Broadway Street Bridge in Lincoln Heights. I can’t imagine how amazing it would be if Angelenos one day are able to access the entire river from start to end at the ocean, our very own version of Cheonggyecheon River linear park.

Welcome to our last in a series of Cal Poly Pomona Coastal Resiliency posts, featuring the observations of 4th year undergraduate students in the Landscape Architecture program.

With today’s post we mark the conclusion of our collaboration with the Cal Poly fourth-year undergraduate studio.  In the course of 11 weeks, the students explored both natural and manmade strategies for adaptations and mitigation for coastal resiliency in Long Beach. Almost as important, as practicing professionals we’ve noted we too learned so much from these “bravely curious” landscape architecture students instructed by Professor Barry Lehrman.

The students presented strategies in proposal of applications to their areas of focus in Long Beach during their final presentation at AHBE. We wanted to share with you some of their amazing strategic diagrams, inventory, and analysis these students have been working on during this quarter.

“Mapping out observed bird sightings in the City of Long Beach, a pattern was shown that not only does the rich ecology try to follow bodies of water, lakes and the ocean, but the areas with the highest density were places with the highest density of people.” – Estevan C. (more…)

I was first exposed to the seminal short film produced in 1977 by the iconic team of Charles and Ray Eames, Powers of Ten as a student of landscape architecture at Cal Poly Pomona. I remember the mind-blowing film even today, one that takes viewers on a visual journey that begins with an aerial shot of a man lounging in a park, gradually zooming upward at scales of 10 further and further away, until the perspective is taken to the edge of the universe. From there the viewer is zoomed back downward back into the hand of the man lounging the park, eventually transported inward into an individual atom within the man’s body.


Welcome to our ongoing series of Cal Poly Pomona Coastal Resiliency posts, featuring the observations of 4th year undergraduate students in the Landscape Architecture program.

The students finished their mid-term review last week, presenting their research, inventory, and site analysis for the city of Long Beach. After forming into five teams, each group explored both soft and hard infrastructure strategies, as well as adaptation and mitigation tactics towards coastal resiliency. It is predicted that in 20 years our sea level will rise by 1 foot. How do we prepare our coastal communities NOW to be resilient towards this climate change? We can no longer respond with familiar strategies and technologies, but we also need to explore new solutions that goes beyond our comfort zone by imagining what resilient urban infrastructure can be.

Students researched mitigation strategies such as the establishment of a living breakwater, a structure designed to shield the coastline and offshore breakwaters by slowing and lessening the impact of sea level rise. Techniques range from artificial reefs, oyster-culture, wetland restoration, and artificial tidal pools. Other strategies for adaptation considered by our student-collaborators included the creation of infrastructure to aid communities prepare and integrate rising sea level through natural system barriers such as wetlands; re-thinking our transportation infrastructure by creating canal-oriented communities was another explored possibility.

Alex W. writes:

As landscape architects, we may be able to implement strategies that do not negatively impact the culture of the coast while also mitigating storm surges and tidal incursions to the communities that live along the shore. The research we have gathered individually and as a class has prepared us to step up into the landscape architect’s number one responsibility: safety toward the user. The difficult challenge we face in attempting to meet this goal is facing nature at the height of its intensity. This will be no easy task.”

I grew up living in Los Angeles, but I hardly ever ventured into Downtown LA while growing up. I remember visiting the Central Public Library, being in awe by the architecture. I also remember taking the bus with my mom to the Fashion District to get fabric. So when our office moved into Downtown Los Angeles on 7th and Hope over 2 years ago, I was surprised by the walkability and energy that Downtown offered.

I decided to take my camera and walk straight down 7th Street as far as my one hour of lunch allowed to document my experience. I chose 7th Street because it takes you through various neighborhoods and districts within Downtown – from the jewelry, theatre, fashion districts, then finally to the Los Angeles Flower Market before turning back. There are some great finds and artifacts along the way that deserves a double take.
