Abstract:
This dataset contains polygons that represent the boundaries of assessment neighborhoods as defined by the DC Office of Tax and Revenue (OTR) Real Property Tax Administration (RPTA). For analysis purposes, RPTA delineates assessment neighborhoods to group properties that are affected by similar economic, political, governmental, and environmental factors.
Assessment neighborhoods are defined by the environment of a subject property that has a direct and immediate effect on its value. The assessment neighborhood is a geographic area (in which there are typically fewer than several thousand properties) defined for some useful purpose, such as to ensure for later multiple regression modeling that the properties are homogeneous and share important locational characteristics.
Assessment neighborhoods boundaries typically follow street centerlines, hydrological boundaries, and boundaries of major properties such as parks and monuments. The current feature class was created by selecting coincident features from the DC GIS snapbase. These included road centerlines, stream centerlines, water boundaries, rail lines, and DC political boundaries. After a new feature class was created, any additional lines required for polygon closure were snapped to existing features using a tolerance of .001 meters.
Purpose:
This dataset is used by the DC Real Property Tax Administration (RPTA) to facilitate analysis and statistical modeling on properties that are homogeneous and share important locational characteristics.
Supplemental_Information:
Assessment neighborhoods are not analogous to Neighborhood Cluster boundaries that are used for planning purposes and political analysis. They should not be confused with the cluster layer or considered to be interchangeable in any way.
