Abstract:
Using data from Charlotte, NC, a New South city without a legacy of heavily contaminated properties, we find the distance from unremediated brownfields—typically former industrial properties believed to have modest contamination—to have no effect on residential sales values, but proposed cleanup and actual remediation have positive, substantial, and significant effects especially within 0.5 miles of the brownfield. Our results are consistent whether we examine all property values within a given distance, such as 0.5 miles, or examine discrete distances, such as 0.3–0.5 miles. An estimate of the benefits is on the order of $4 million.

http://tinyurl.com/jbqyqau the authors report that the median brownfield size ... is nearly 262,000 square feet.,,, Based on tables 2 and 3, a 10,000 square foot increase in the size of a brownfield results in a decrease in property value of about 3%. For an otherwise comparable house valued at the median of $95,000 (adjusted using a 1995 price index), the house near the brownfield loses almost $3,000 in value for each 10,000 square foot increase in the size of the brownfield.

If stage 2 is reached where a developer applies for constructive notice, as is the case for about 40% of the transactions in this sample, a house within 0.5 miles from the brownfield experiences an increase in value, with the size of the increase decreasing with the size of the brownfield. For the median size brownfield of 262,000 sq. ft., the net effect is on the order of 0.3 – 26.2*(0.005) = 0.17 or 17%. The $95,000 median house would now be worth $111,000 given the developer intentions, a gain of almost $16,000. For our data sample of approximately 500 houses within 0.5 miles of a given brownfield and based on median values, 200 homes (40% of 500) will gain the premium for an overall gain of around $3,230,000. We attribute these benefits to the market expectation that a developer applying to the brownfields program expects to remediate and eventually redevelop.

The benefits of the brownfields program increase further where there is actual remediation (and would increase again with redevelopment). Again choosing the 0.5 mile distance, the lift to property value is a little over 10% (bearing in mind that homeowners out to 2 miles will benefit, and homeowners within 0.3 miles are actually worse off). The house that had already appreciated by almost $16,000 would now add approximately $11,000 to $122,300. Approximately 15% of sales took place after remediation. For the sample of 500 houses within a 0.5 mile of the nearest brownfield, there is an additional $10,000 in benefits for the 75 homes that sell after remediation, or an additional $830,000, bringing the overall gain to $4.1 million.
