This article reports the results of an experiment to estimate the value of
an urban greenway and to test the validity of contingent valuation (CV), an
d discusses the implications of the results for greenway planning. The expe
riment concerned people's willingness to pay (WTP) for greenway projects in
a publicly designated greenway in Indianapolis, Indiana, that is mostly in
private ownership. In the summer of 1997, a CV survey and an actual solici
tation for funds were mailed simultaneously to split samples of greenway pr
operty owners, greenway renters, and county residents. The survey and the s
olicitation asked about WTP for educational, cleanup, and other projects by
the White River Greenways Foundation related to management of the Crooked
Creek Greenway. The proportion of respondents willing to pay was much highe
r in response to the survey than the actual solicitation, and hypothetical
mean WTP was much greater than the actual contributions. The results sugges
t that people value greenways, but that greenways mainly in private ownersh
ip may have mainly local value. These results provide evidence that CV expe
riments can help identify sources of support and suggest strategies for pla
nning, but do not provide precise estimates of the value of public goods.
