Small scale urban green infrastructure projects can provide local ecological services that should be accounted for in project assessment. Benefits assessment can be expensive and time consuming; benefit transfer provides an economical alternative, but the quality of the analysis depends upon available data. A best-case scenario for many applications of benefit transfer is to utilize a conforming meta-analysis. In this paper, we use the meta-analysis of Bockarjova, et al. (2020) to predict ecological benefits of small scale urban green infrastructure investments in Hinesville, GA. In doing so, we implement a censoring procedure on the benefit transfer function to permit analysis of small-scale (less than one-hectare) projects. We find evidence of substantial net economic benefits, with estimates ranging from $738,312 to over $5.5 million; positive benefit-to-cost ratios are robust to substantial cost increases (4 times the estimated costs). We provide guidance for how to apply these methods to other contexts.
