Physical Dimension
Percent Home Ownership
– The percentage of all residential units that were owner-occupied in
2010.
2010 Census data on homeownership was collected for each block group (NSA). The number of
owner-occupied units were divided by the total occupied-units to get the percent of home
ownership for each NSA. A reverse Z score was used to prioritize NSAs with lower home
ownership percentages.

Percentage
of Single Family Dwellings Older than 50 Years
– The percentage of single family
dwellings older than 50 years.
By utilizing the tax parcel database, each tax record was assigned to an NSA using GIS. Each tax
record was analyzed for residential use and age. The records were summarized for each NSA by
single family units.
For each record, houses older than 50 years were identified. The total number of single family
dwellings older than 50 years was then divided by the total number of single family dwellings for
each NSA to get the percentage of single family dwelling older than 50 years.

Percent Code Enforcement
– A score based on the code enforcement violations for each NSA.
The violations recorded for 2012 were geocoded and assigned spatial attributes with GIS. The
data points were identified with NSA boundaries to get the total number of code enforcement
violations for each NSA. Each violation was ranked in severity based on a multiplier described
below:
•
Properties coded as demolitions were given a score of 5. These structures are 50% damaged or dilapidated.
•
Properties that are ordered to board up their windows and doors and secured were given a score of 3. These
structures are vacant and are considered unsafe.
•
Properties that are red tagged are given a score of 2. Virginia Natural Gas has determined an unsafe
condition exists.
•
Structures that have property maintenance violation are given a score of 2.
•
Properties that have weeds, debris, or graffiti are given a score of 1.
The scores for each NSA were summarized and divided by the total number of parcels in the
NSA. The values were classified into the following categories:
High – 0.22+
Medium – 0.10 – 0.22
Low – 0.0 – 0.10
