This research explores the notion of urban accessibility, defined as the spatial separation between dwelling units and 32 types of destinations including shopping, open space, and public services. Using data on the roughly five million residential land parcels in Southern California, we use network analyses and multilevel regression modeling to determine what it is about homes that make them more or less accessible to a wide variety of destination types. In most places across the region, older homes, smaller homes, and multifamily residences have a positive relationship to accessibility; however this varies widely across counties and cities.
We typically think of neighborhoods as fairly homogeneous areas within cities. Nonetheless, some neighborhoods are highly mixed and others are not based on things like income, racial composition, age, land use, and the type of housing they contain. We analyze mixing across these dimensions in Southern California, then ask what are the consequences of mixing for economic dynamism in neighborhoods.

The 2014 Southern California Regional Progress Report was prepared by researchers with the School of Social Ecology’s Metropolitan Futures Initiative, which aims to build a base of knowledge to guide policymakers in improving the overall quality of life in the Southland. It is the second installment in a biennial series of Regional Progress Reports.
The inaugural Southern California Regional Progress Report was prepared by researchers with the School of Social Ecology’s Metropolitan Futures Initiative, which aims to build a base of knowledge to guide policymakers in improving the overall quality of life in the Southland.

An important finding is that the negative relationship with racial/ethnic minorities has decreased substantially in recent decades.]
- Regional Leadership in Air Quality Program – Marlon Boarnet (Professor of Planning, Policy, and Design) and Lindell Marsh (attorney and lecturer in Planning, Policy, and Design) convened a series of meetings with leaders of key regional agencies and stakeholders in 2009 that produced a common understanding of the region’s land use – air quality – transportation – energy infrastructure challenges. This effort is supported by SCAG, leading planning firms, UC Irvine, and Cal State University San Bernardino.
- Community Scholars Program – Supports the capacity building and organizational development of non-profits through applied “place-based” research. Recent Community Scholar projects include the development of a “foreclosure counseling” program for the Neighborhood Housing Services of Orange County and the evaluation of a community building initiative by the Office of Orange County Human Relations (OCHR). The latter resulted in OCHR securing a $225,000 continuation grant from the St. Joseph Health System.
Professional Reports: A professional report is an analysis of a “real-world” planning problem or a detailed simulation of a planning project by students in UCI’s Master’s in Urban and Regional Planning Program. Students diagnose a planning problem, select appropriate analytical methods to assess the problem, and identify, evaluate, and recommend strategies to address the problem. Examples of past reports include:
“City and School Partnerships: Strengthening the Community of Moreno Valley with a Joint Use Agreement”
Client: Moreno Valley Unified School District
“Creating, Administering and Overseeing Owner-Occupied Affordable Housing in Orange County”
Client: Neighborhood Housing Services of Orange County
