00:01Thanks. Hi. I'm Abby, and I'm presenting an overview of redfields, greendfields, Los Angeles…
00:05…the work my student team did for our final project in the Master of Landscape Architecture program…
00:10…at Cal Poly Pomona.
00:12Our team was Dakotah Bertsch, Mike Boucher, Eran James, and myself.
00:18We were approached by the Verde Coalition in Los Angeles to help create a case study on how to jump-start LA's economy…
00:24…by converting redfields to greenfields.
00:27In our project, we define redfields as vacant, foreclosed, or underutilized urban properties.
00:33And greenfields are any green space that benefits the community.
00:37The vision of R2G-LA is to transform the urban area of LA and improve its environmental, economic, and social health.
00:47This diagram shows the process we used to explore the parameters of R2G-LA.
00:51I'll be following it as an outline for the presentation.
00:55In order to understand the need and the potential benefit greenfields could have on Los Angeles, the city was studied as a whole.
01:01This map relates the city shape I'll be showing later on to the context.
01:05Note the city boundary.
01:08Our regional research focused on issues that fall into the three broad categories, social, economic, and environmental.
01:15The majority of Los Angeles residents are suffering from park inequality.
01:20There's a lack of healthy food options in low-income areas.
01:24Property values and transaction rates have plummeted and vacancies are high.
01:28Los Angeles' water supply and storm water system are unsustainable.
01:33The water quality is poor.
01:36Summer temperatures have been rising.
01:38Native plant communities are becoming endangered, and Los Angeles has the worst air quality in the nation.
01:47The goals and objectives of R2G-LA address these regional issues…
01:50…and would contribute vibrancy to the city's social, economic, and environmental health.
01:56To select neighborhoods, we narrowed our focus to an area of need that was both economically disadvantaged as well as park poor.
02:04The third map shows this area of need.
02:06Economically disadvantaged was defined as areas below 80 percent of the state's median income.
02:11Park poor areas have less than 10 acres of park per thousand people within walking distance.
02:18For further refinement and to choose neighborhoods with different characteristics…
02:21…typologies were created based on land use and density within the area of need.
02:26We simplified the land use and density maps, and three categories were created…
02:31…high-density residential, low-density multifamily, and residential on the industrial fringe.
02:37Finally, we chose three neighborhoods for further investigation.
02:41Westlake represents high-density residential.
02:44Lincoln Heights represents residential on the industrial fringe.
02:48And Florence represents low-density multifamily residential.
02:53The topography of each neighborhood varies.
02:56Each neighborhood is roughly the same size at two and one-half square miles.
03:00The next few slides show information clipped to a parcel map.
03:05The land use shows as institutions, commercial corridors, multifamily residential in all neighborhoods…
03:09…and industrial use surrounding Lincoln Heights.
03:14Though two of the neighborhoods have parks, they're still park poor because of the high density in Westlake…
03:19…and barriers to access in Lincoln Heights.
03:23Westlake has the highest population. It's also the most dense.
03:29For redfield inventory, we did a combination of mapping and ground truthing to verify data.
03:35We started with redfields from CoStar, a real estate data provider.
03:39However, during ground truthing, we found many more sites that we considered redfields.
03:44Overall, we found 138 redfields with a total of 67 acres. The average size was a half acre, median size was a quarter acre.
03:56Then we did redfield analysis.
03:59In this phase, we identified greenfield types, recorded redfield characteristics, and did two analyses.
04:05Greenfield types addressed the goals and objectives previously established.
04:09Using a combination of all four greenfield types will benefit all three systems.
04:17Urban agriculture addresses the need for local fresh produce.
04:22Recreation greenfields provide people with a space to exercise and mentally recharge.
04:26Community greenfields give community members an opportunity to socialize and exchange goods and services.
04:33Ecology greenfields provide natural functions like pollutant cleansing and habitat for native species.
04:39With these greenfield types in mind, we did further inventory of redfield characteristics.
04:46For a capability analysis, sites were capable of supporting each greenfield type if they met the listed criteria…
04:53…and we mapped these results in stack bar charts so you could see all the information at once.
04:58All sites were capable of at least one or more greenfield type.
05:03Next suitability analysis narrowed down which sites were most suitable according to refined criteria.
05:08We selected sites that cumulatively met both or one of these criteria and mapped the results in a stack bar again.
05:15You can see this is a narrower selection, and it provides a starting point for converting redfields to greenfields.
05:23We selected four of these most suitable sites for examples of how to design using the greenfield types.
05:31Each site underwent rigorous inventory and analysis to match designs to their context.
05:35A capability analysis fit program features to the site analysis, and designs reflect this analysis.
05:42Overall, each site is an opportunity to incorporate a variety of solutions that benefit the community.
05:47The greenfield types are best used in combination to provide as many benefits on the site as possible.
05:55I'm only going to go through one of the site designs because of limited time.
05:59This vacant lot is on Broadway and Lincoln Heights.
06:01Part of the site…Part of the site features very sloped terrain with full solar access.
06:07The other part of the site is a vacant, paved parking lot.
06:14Broadway is a large commercial boulevard running through the residential neighborhood, and the site is surrounded by schools.
06:21The design for Lincoln Heights logo brings this lot as alive as a community resource.
06:25The community garden has a place where students and community members can share knowledge.
06:29Gardening classes are held in the garden and in the community classroom.
06:33The orchard invites neighbors to pick oranges while taking in views of downtown Los Angeles.
06:38The former parking lot is transformed into a vibrant community plaza where a farmers' market is held.
06:43The market provides healthy food options for a neighborhood with little access to fresh produce.
06:48It also provides an economic venue that supports local agriculture.
06:52The design works well with the site's topography, location, and sun exposure.
06:57The site features all four greenfield types.
06:59The garden is a form of urban agriculture.
07:01The classroom, farmers' market, plaza, and juice stand are part of the community functions.
07:06The plaza and garden provides recreational opportunities…
07:09…and the oak tree, permeable paving, and bioswale provide ecological functions, finally, extrapolation.
07:11We estimate over 2,100 redfields having over a thousand acres within the disadvantaged area…
07:20…based on the numbers found in our neighborhoods.
07:24Greenfields will be scattered throughout the city.
07:26They may seem small, but if you look at the cumulative effect, R2G-LA would add more park acreage to Los Angeles…
07:34…than Golden Gate Park in San Francisco.
07:38Additionally, greenfields would be more accessible than a single large park in only one part of the city.
07:43This is Florence in South Los Angeles now, and with R2G, nearly every resident would have easy access to a park.
07:53Cumulatively, greenfields could help fulfill regional goals and objectives with decentralized small-scale infrastructure…
08:00…that in the long term enhances social, economic, and environmental systems throughout the city of LA.
08:06Thank you. Here's my contact information.
08:08We also have a book online. It's about 110 pages, and you can find it on issue.com if you search for the title…
08:15…Redfields to Greenfields Los Angeles. Thanks.
