Scoring:
Each component is assigned a score between 0 and 25 where: 0 is not suitable
and 25 is highly suitable. The component scores are a reflection of the current
interrelationships among the set of spatial characteristics; the relationships are
relative to local conditions, there are no external standards, thresholds or
benchmarks.

AHS:
A GIS model where variables are combined in four components to define the
degree in which a given area is suitable for the development and preservation
of affordable housing

Note:
In this example all the variables within the same component were equally weighted. Alternatively we could use a weighting tool to capture the preferences of the community.

Evaluating the Assisted Housing Inventory

Method:
• Each property in the Assisted Housing Inventory in Orange County was assigned a score based on the average of the AHS result in an area defined by a radius of 400 meters from the property location.

Transit Accessibility:
Estimated through three steps: • Where does the transit route go, especially in terms of employment opportunities (density and proximity). • Transit distance and time taking into account routes and frequencies. • Proximity and density of transit stops in relation to residential locations.

Program analysis 1: HUD properties tend to have higher scores, mainly because of high Transit and Neighborhood Accessibility and low Rental Costs.

Evaluating the Assisted Housing Inventory
19
Age analysis 2: Newest properties tend to have lower scores because of low Transit and Neighborhood Accessibility although they fare better in terms of social characteristics. However, properties built in the 2000’s show higher scores and better accessibility. Does this reflect current policy priorities and outcomes of the UAC?

Relationships of AHS scores with other variables
20
AHS scores and historical sitting: Properties “built” in the 1980s and 1990s: The trend towards the suburbanization of assisted housing properties intensifies, AHS scores for these two decades are lower.
