Last week, Cascade Policy Institute released a report investigating the disappearance of backyards throughout the Portland metropolitan region.
In 1995, the average lot size for a new home in Washington County was 15,000 square feet. Today, new residential housing projects in Washington County list 7,000 square foot lots as “executive housing,” an apparent luxury only for the rich. Has the American Dream disappeared in the Portland region?
The purpose of this research project was to see if the disappearance of backyards was real or an illusion. After examining the adopted land-use plans and accompanying zoning codes of the three metro counties and a cross-section of local cities, it became clear that private backyards in fact are being zoned out of existence, in order to comply with state and regional land-use mandates.
All new development projects on lands recently approved for urban growth boundary expansion in the Portland region have high-density overlays that prevent traditional backyards (roughly 4-5 units/acre), except for a small percentage of all units. In addition, many older neighborhoods with large lots are experiencing an epidemic of teardowns, due to the artificial shortage of buildable land. Homes with large yards are being purchased, demolished, and replaced with several homes or towering apartment complexes.
As a result of density mandates, homebuyers are increasingly paying more while getting less in the way of private open space.
According to report author John Glennon, “Local planners know that most people prefer lower-density neighborhoods; yet zoning codes have been written to take that option away.”
Cascade Policy Institute President and CEO John A. Charles, Jr. noted, “As Metro prepares for another round of possible growth boundary expansions, elected officials should think hard about the effects of land-use regulation on livability. In a state that is already 98% open space, there is no reason to create an artificial shortage of buildable land. The State Legislature should enact reforms this year to remove high-density mandates from local governments.”
