About the Map
The Residential Growth Map is designed to show Single-Family Residential
(SFR) growth patterns relative to Maryland's Priority Funding Areas
and Protected Lands from 1986 to 2007.
Growth is measured by both the number of
parcels developed inside and outside of Priority Funding Areas and the acreage
used by those parcels.
The map tool is based on Google Maps, so if you have used
any of the popular online web-mapping tools from Google, Microsoft, Map Quest,
or Yahoo, you should be comfortable
with moving around the map.
